DEDICATION

This report is dedicated to the captain and crew of the M.V.Liktanur. For ten years the Liktanurs11and III have ser~red as home and workplace for much of each medical mission to the MarshallIslands. Throughout this time it has been the good fortune of the medicaI program to have theexcellent support of the ship’s crew. More impotzantly, that good fortune was extended to thepopulation served by the medical team: the emergency rigging of oxygen tanks to treat hypoxicpatients, lighting of a small airstrip at night to facilitate an emergency air evacuation. radio liaison.transportof patients between the atolls and to and from shore. and the emergency repair of medicaiequipment are just some of the non nautical activities that benefited the medical missions. Now. a newsupport vessel for work in the~arshall Islands has come under contract to the Department of Energy.Therefore, on the departure of the Liktanur, we would like to acknowledge our debt to Capt. KeithCoberly Monroe Wlghtman. engineen Jim Whitney and Jan Kocian, first mates Cisco Peru, cook LesNunes, boatswain; Tony Ned and Mathan Almen, seamen: and other crew members who, for shomerperiods, also contributed to the effectiveness of the missions. We thank them for a job well done.

IN MEMORIAM

Two former members of the Brookhaven medical team who participated in several surveys diedduring the past year. Colonel Austin Lowrey, Jr., died at the age of eighty-six. He was a well-knownophthalmologist with a long career in the army. He was a most kind and generous person andcontributed a great deal to the evaluation of possible radiation effects on eyes. Dr. Leo Meyer, who diedat age eighty-two, was a well-known hematologist and was Director of the Sickle Cell Anemia Programof the Veterans’ Administration. He made outstanding contributions to the program in evaluatinghematological radiation effects. Leo will be remembered for his joviality, for always having a joke ready[o cheer us. Both of these men were well liked by medical teams and the Marshallese people. and weshall truly miss them.

INTRODUCTION

This report updates. through 1987, the medi-cal findings on a population of .Marshalleseaccidentally exposed to radioactive fallout in1954. The Marshall Islands Medicai Program ofthe Medical Department, Brookhaven NationalLaboraco~, issues these summaries for distri-bution to institutions and individuals world-wide who are concerned about the adverse med-ical consequences of radiation exposure ingeneral or, in particular. the plight of theradiation-exposed Marshallese.

The exposed Marshallese population origi-nally comprised 64 persons on Rongelap Atollwho received an estimated 190 rads of whole-body external gamma radiation. 18 on AilingnaeAtoll who received 110 rads. and 159 on UtirikAtoll who received 11 rads. In addition. therewere 3 fetuses on Rongelap, 1 on Ailingnae. and8 on Utirik. each of which received equivalentwhole-body doses. Because of radioiodines inthe fallout, the thyroid gland received an addi-tional exposure that was much greater than thewhole-body dose, although its magnitude wss.in part, a function of age at the time of exposure(Lessard et al.. 1985).

The content of this repon is restricted to themore recent medical findings, some aspects ofwhich bear on late effects of radiation exposure.Those feat u res of the Marshall Islands MedicalProgram by which medical diagnosis and treat-ment are prowded are discussed. For detailedinformation on the nature of the 1954 falloutand the acute effects suffered by the population.the reader is referred to several earlier publica-tions [Bond, et al., 1955; Cronkite et al.. 1955:Cronkite et al.. 1956: Conard et al., 1957).Otherreports provide reviews of delayed effects of theexposure (Conard et al., 1980 Conard, 1984:Robbins and Adams, 1989).

EXPOSURE GROUPS

The medical program examines and treatsabout 800 persons annually. However, the popu-lations on which this report is based includeonly the exposed persons and a selected groupof unexposed individuals. In December i 987.the number of exposed persons was: Rongelap -50, Ailingnae - 12, and Utirik - 112. For mostpurposes in (his report the Rongelap and

.%lin gnae groups are combined and referred toas the Rongelap group, for those personsexposed on Ailingnae atoll were \’isiting fromnearby Rongelap at the time of the fallout. .Usoexammea was the Comparison group that datesfrom 1957 when 86 unexposed people fromRongelap were selected so that the Comparisongroup approximated. in age and sex distribu-tion.the exposed Rongelap group (Conard et al.,1958). Sixty persons remain in this group,against which the overall survival of the exposedpopulation is compared (Figure 1). However, alarger unexposed group is also followed. Cur-rently numbering 135, the age and sex distribu-tions of its members were statistically similar tothose of the Rongelap and Utirik groups in 1982(Adams et al,, 1983). Included among the 135are most of the remaining 60 individuals selectedin 1957. It is this expanded unexposed popula-tion that is used for statistical comparisons ofyear-to-year medical events: this provides thebaseline prevalence from which any unex-pected consequences of the radiation exposure .can be identified.

THE MARSHALL ISLANDSMEDICAL PROGRAM

Policies:The Marshall Islands Medical Program pro-

vides medical care twice yearly to the exposedpopulation by visiting the islands where mostnow reside, namely Rongelap (and, temporarily,Mejato ), Utirik. Ebeye, and Majuro. In addition,the medical team provides health care to a con-

siderable number of unexposed persons. AHtheinhabitants of Rongelap. Me.jato. and Utirik areeligible for medical attention at the time of theteam \isits to those islands. Team physiciansneed not be aware of the status of radiationexposure of the individual patient becausehealth care delivery is the same for everyone.The only difference allotted to the exposed pop-ulation ISa U.S. Department of Energy-sponsoredreferral system to the Marshallese health caresystem or to tertiary care facilities m the UnitedStates for diseases that can reasonably be con-sidered to be radiation-related or for diagnosisof such diseases. Unexposed persons aredirected into the referral channels of the HealthSenlces of the Republic of the Marshall Islandswhereby referrais are assigned on the basis ofpriorities set by a medical committee in Majuro.

.Any exposed person who has, or who mu?hthave. a malignant neoplasm. IS referred tosecondary or tertiary medical facdities for adefinitive evaluation and for therapy if a lesion Efound. The usual hospitals to which patients arereferred are in Honolulu and Cleveiand. the lat-ter because of the presence there of a preemi-nent thyroid surgeon who has long beeninvolved with the exposed and Comparisongroups of Marshallese.

The medical program also dispenses prima~medical care and preventive medical services,such as immunizations, during \mits to theexposed population. In bringing modern facili-ties for diagnosis and treatment of disease to theexposed Marshallese, the physicians of the med-icai program come into contact wxh childrenand other family members of the exposed. aswell as other inhabitants of the Aands. It hasbeen the policy of the Department of Ener~ tosupport the medical program in its efforts toprovide primary medical care to these individu-als on the basis of humanitarian need and asresources permit.

The medical direction of the Marshall IslandsMedical Program and the orgatuzation of themedical missions to the Marshall Islands arecentered at Brookhaven National Laboratory.The staff of the program includes a physician-director. an administrator. and a technical spe-cialist at the Laboratory, and a .Marshalleselaboratory technician on Ebeye. .+t the time ofthe missions a variety of physicians are chosenfor the medical team. They are skilled volun-

teers. primarily faculty from medical schools,often \vith past exp,.rience with the program.Logistical support is provided by the Depart-ment of Energy, capably facilitated by Holmesand Xarver. Inc.. Honolulu. HI. The MarshallIslands government. as requested. temporarilyassigns nurses. transistors. and other healthcare workers to each mission.

Although there are two medical missions eachyear. in the interim the exposed population hasaccess to the MarshaUese health care system. Toexpedite exchange of medical information,copies of all examination and laboratory datafrom the Marshall Islands Medical Program areforwarded to the Marshall Islands Health Ser-vice hospitals on Ebeye and Majuro and to thespecial programs set up for persons from theradiation-affected atolls, currently the 177Health Care Plan \vith administrative offices atthe Majuro hospital. In addition. copies of theexaminations and laboratory data are given tothe examinees.

A computer program with data base wasdeveloped for portable (lap-cop) computers.Computerization of the clinical data permitsrapid access while in the field to all findingsobtained during the preceding five years ofexaminations and to selected data collectedover more than thirty years. Itis hoped that inthe near future the development of compatibleprograms by the Marshallese 177 Health CarePlan wdl permit sharing of up-to-date problemlists and other medical record items that areimportant to effective continuity of care.

The Marshall Islands Medical Program. as asateilite clinic of the Clinical Research Center,Brookhaven National Laborato~, is accreditedby the Joint Commission on Accreditation ofHealthcare Organizations. a nationwide organi-

zation that sets standards of performance forinstitutions dispensing medical care and moni-tors compliance with those standards, By volun-tary participation in the accreditation process,the Marshall Islands Medical Program receives avaluable and impanial external review of itspolicies and procedures, ss well as an assess-ment of the adequacy of the services it provides.Laboratory and radiological services, medicalrecords, patient satisfaction. pharmaceuticalset-vices, and clinical competence of physiciansare among the many items reviewed by the JointCommission,

Much medical data unreiated to radiationexposure is acquired during each medical mls-+ion. Some of this information. from exposedand unexposed indi~tiduals. is relevant to healthcare throughout the Marshall Islands. Conse-quently, public health reports. based on medicalteam observations unrelated to radiation. havebeen submitted periodically to the Health Servi-ces of the Republic of the .Marshall Islands. Thetopics during this reporting period have includedthe following

1) Serum lipids in Marshallese2} Pediatric growth and development (ananalysis prompted by observations of med-ical team physicians that Rongelap child-ren, following their transfer to Mejato,were not maintaining their positions oncharted growth curves )3) Pediatric audiometry4) DentaI conditions on Rongelap andUtirik5) Chlamydia infections in Marshallesewomen6) Large optic disks (a relatively frequentfinding by medical team ophthalmologists)

Some signifkant observations in these andearlier public health reports were published inmedical journals. Moderately elevated serumuric acid levels were noted in many Marshalleseand the frequency of this finding and that ofgout were analyzed (Adams et al.. 1984).Toxo-plasmosis was identified as a serious healthhazard in the Marshall Islands. with an esti-mated 200 persons being visuaily impaired andan inc]dence of chorioretmitis of 273 caseslyearl 100,000 seropositive persons (.Adams etal., 1987). Hepatitis B, the subject of a serologicalsurvey described in a previous BrookhavenNational Laboratory report (Adams et al.,1985), constituted another serious public healthproblem (Adams et al-, 1986). The prevalence ofanemia in children was described. and normalranges for hemoglobin level and erythrocfiemean corpuscular volume for ,Marshallesechildren were derived (Duntzy et al.. 1987). Thelatter were found to be identical to those ofchildren in the United States. Because of thedevastating effects of diabetes mellitus amongthe Marshallese, an effort was made to deter-mine if a dietary deficiency of chromium, a traceelement that is relevant to glucose tolerance.contributed to the problem. The analytic proce-

dure used was too insensitive to quantitateblood levels of chromium, but during the analv-sis it Ivas found that bromine levels were higherthan those reported for any other population(Wielopoiski et al.. 1986). The reason for this isunknown: further, the levels of bromine thatwere detected fall far short of its known toxiclevels. The observation by team ophthalmolo-gists of large optic disks in many personsprompted another report to the MarshaUeseHealth Services because the associated increasein disk cupping could be misconstrued by physi-cians as representing glaucoma. The high pre-valence of the condition indicates Marshalleseare unique among all populations in whom suchmeasurements have been obtained (Maisel et al.,1989).

Procedures:The exposed population. which now numbers

163, must be considered at increased risk formalignant disease as a late complication ofradiation injury. Therefore. the medical pro-gram has in place a cancer-oriented annualhealth evaluation. The examination follows the‘guidelines of the Anerican Cancer Society andincludes a medical history, complete physicalexamination, advice on decreasing risk factorsfor cancer, advice on self-detection of lesions,annual pelvic examinations and Papanicolaousmears, stool testing for blood, blood count, andurinalysis. Several new diagnostic procedureswere incorporated into the medical missions inthe past three years. Because of the develop-ment of x-ray fdms and cassettes that signX]-cantly decrease radiation exposure, annualmammography is offered to all exposed womenand to alI unexposed women forty years of ageor older. For persons over the age of ffiy years,flexible sigmoidoscopy is offered every threeyears or whenever clinically indicated. An tdtra-sound machine has been acquired that greatlyincreases the diagnostic capabilities of the med-ical team, especially in managing acute prob-lems seen at the time of team visits. For thyroiddiagnosis, needIe biopsy of selected thyroidnodules has been instituted in an effort to avoidsurgery and the subsequent loss of normal thy-roid tissue in patients with benign nodularlesions. Because of earlier medical programobservations it is known that the exposed are atgreater risk for certain endocrine problems andfor this reason they receive annual thyroid-

func[lon blooa tests and thyroid examinationsby a specialist in endocrinology or thyro]dsun?ery. Other tests are performed on a regularhas~ m an attempt at early detection of malig-nant nonthyToldal les]ons. There is also ongoingmonitoring for clinical evidence of immunecompetence. for exposed persons may be atincreased risk for unusual manifestations ofinfecuous diseases.

Nedical examinations and services performedduring this three-year reporting period wereconducted primarily aboard the Liktanur 11andthe Liktanur 111, vessels chartered from U.S.Oceanography Exceptions, as in the past.included the use of Brookhaven National Labor-atory facilities on Ebeye and, when necessary,.Marshallese medical dispensaries on Rongelap,Llink. and Mejato. Laboratory support duringthe medical missions is provided by severaltechnicians. Routine blood counts are performedon a J.T. Baker 5000 electronic particle counterand sizer. Leukocyte differentials and phasecontrast platelet counts are part of each hemo-gram. A variety of nonhematological testing ser-\Ices is provided. including bacteriology, stoolexamination. and urine testing. In the past abattery of manual clinicai chemistry tests wasearned out using commercial spectrophoto-metric kits. Recently, however, Eastman-KodaksDT-60 and D’13C analyzers were added toincrease the ~ariety of chemistry tests availablein the field and to improve the turn-around timefor results: this has significantly improvedlaboratory operation. Fortunately, there havebeen few problems associated with transpon.operation, and handling of the new” equipmenton board ship, even during bad weather. ABeckman Electrolyte 2 analyzer is used to mea-sure sodium and potassium in serum and urine.Roentgenographic services are performed witha Bennett standard x-ray unit and mammo-graphy unit. both of which are contained in aseparate module on the deck of the ship. Serumis usually collected from most exarninees andfrozen for subsequent testing. Referral laborato-ries have included Bio-Science Laboratories andAccupath in Honolulu for special chemistriesand serologies: Pathologists’ Laboratories, Inc..Honolulu, for Papanicolaou smears and othercytology; Brookhaven National Laborato@clinical laboratory for general chemistv andalpha fetoprotein analysis: Hazelton Biotech-

Saenger Radio-isotope Laboratory, University of Cincinnati. forantimicrosomal and antithyroglobuiin antibodytesting (Dr. Harry Maxon).

The .Marshall Islands Medical Program isdeepiy indebted to the many outstanding physi-cians who, despite the inevitable personalinconvenience. participated in the medical team\isits of 1985-1987. It is fair to say that they arethe heart of the program. Drawn from excellentmedical centers throughout the United Statesand from private practices, these physiciansprovide the program with a wide range of up-to-date clinical experience and perspective thatcontribute to better patient,care. The physiciansinvolved in the 1985-1987 missions are listed inAppendix A, and represent the following medi-cal specialties:

Internal MedicinePediatricsInfectious DiseaseCardiologyObstetrics/ GynecologyOphthalmologyEndocrinologySurgeryGastroenterologyFamdy PracticeGeriatricsAllergy/immunologyDermatologyNeurologyPediatric Dentistry

The participation of many excellent medicalspecialists undoubtedly has been a major factorin the acceptance of the Marshall Isiands Medi-cal Program by the population it serves. Thepercent of persons in the exposed and Compari-son groups who appear for the voiuntary exam-inations remains high. For the current reportingperiod the annual acceptance rates were:

MEDICAL FINDINGS

Overall Survival:After thirty-three years there continues to be

no significant difference in the sunival curves ofthe high-exposure Rongelap group, the low-exposure Lkirik group, and the unexposed Ron-gelap population followed for the purpose ofcomparison (Fig. 1). Estimates of the sum’ivaldistribution by the actuarial life table method\vere analyzed by Mantel-Cox and Breslow sta-tistics for testing the equality of the survivalcurves. The “p” values were 0.68 by both tech-niques. In the Brookhaven National Laboratoryreport covering January 1983 through Decem-ber 1984, it was noted that Okajimaet al. (1985)suggested that medical programs providinghealth screening might lead to an underestima-tion of the effect of radiation on mortality. Inparticular, it was postulated that this couidexpiain the iower agespecflc death rates fromail causes among Nag=aki A-bomb survivors,compared to a controi population. The effect ofmedicai examinations on the survivai of theexposed Marshaliese is unknown. On the onehand about 15 percent of the Comparison groupseiected in 1957 is no ionger seen because thoseindividuals have voluntarily foregone examina-tion. In addition, BNL referrais for the Compari-son group are channeied into the MarshaiieseHeaith Services system. whereas seiected medi-cal probiems in the exposed groups can bereferred directiy to tertiary care facilities in theUnited States. On the other hand. the exposedpopulations of Rongeiap and Utirik have received

equivalent medical attention Irom the BNL pro-gram since 1972. and yet. despite the far higherradiation dose received by the Rongeiap group,the su nivai tunes are similar.

.Inother factor that contributes to the diffi-culty in interpreting differences in the groupsurvivais in Fig. 1 is that the population used toconstruct the “’Rongelap unexposed” curve wasseiected in 1957. and it is in that year that theirsuntivai is graphed as one-hundred percetm i.e..data from three years of observation, duringwhich some deaths occurred. had aiready beenacquired from the two exposed populations.

Causes of Recent MortalitwThe number of deaths occurring in the iast

three years are as foiiows: Rongeiap exposed - 2;Cltirik exposed -9: Comparison group -10. Thespecific ciinicai situations are described beiow.

the death certificate of this” 8 I-year-oid womanin June 1985 were ““Inanition” and “Senility.”When seen in March 1985. she had a normalbiood pressure and cardiac examination reveal-ed “premature beats.” In 1984 she was noted tohave cataracts, atriai fibrillation. and complaintsof urinary incontinence, some cough, constipa-tion, and joint pains. Her hemoglobin was 12.7g(di. the mean corpuscular voiume was 92 fl,and the white biood ceii count was 6,600 per U1with a normai differenciai.

Subject No. 11. This 81-year-oid man died in1987 of unknown cause. Diagnoses made duringthe preceding four years inciuded severe osteo-arthritis, chronic obstructive pulmonary dis-ease with builous emphysema. macrocWic ane-mia that was being t mated with vitamin B12injections, cataracts, and ‘organic brain syn-drome.” He had declined a medicai examinationwhen visited at his home in September 1986. butdid not appear acuteiy iii at that time.

Laboratory Findings:

A review of average blood cell counts of thedifferent exposure groups during the three-yearreporting period does not reveai any systematicdifferences among groups. Figure 2 is a contin-uation graph in which the exposed groups areportrayed in relation to the Comparison group.Table 1 gives the actual mean counts of formedblood elements of the different groups and iden-tifies counts which differed significantly fromthose of the Comparison group.

Biochemical test results are iisted by individ-ual identification number in Appendix B.

Neopiasms:

Thyroid nodulesSurgery for palpable th~oid nodules was per-

formed on five persons in 1985 and one personin 1986. No new iesions were detected in 1987.The specific diagnoses, determined by an expert “panel of pathologists, are listed -in Table Z, andTable 3 gives a summary of all nodules diag-nosed throughout the medical program. Thebenign thyroid nodules include adenomak. ade-nomatous nodules, and occult papillary carci-nomas. The adenomatous nodules are includedin the tabulation even though it is highly debat-able that they are true neopiasms. The occultpapillary carcinomas are. \vith rare exceptions,“harmless tumors” (Sampson. 1976). A recentlyreported autopsy series from the FederalRepublic of Germany found occult papihrycarcinomas in 6.2% of 10’20 thyroid glands.Almost half of the tumors were multicentric and14’,%had regional lymph node metastasis (Langet al., 1988). Since there was no predilection forage it was concluded, as in earlier studies, thatoccult papillary carcinomas have no propensityto cause clinically apparent thyroid ,disease.However. controversy continues on how the clin-ical diagnosis of occult papillary carcinoma is tobe made (Schneider et al.. 1980), and someauthorities would accept that diagnosis only ifthe tumor were an incidental finding at surgery.Since some of the purported occult papihrycarcinomas removed from the Marshallese

Fig. 3: The amrual of cases w?h thyroid nodules and

It appears that there is an reverse correlation

between the radiation dose absorbed by the thy-

roid and the time after exposure for develop-ment of the benign adenomatous nodules (Fig.-1). However. since the thyro]d-absorbed radia-tion dose w-as determined primarily by ageatexposure I children receiving greater doses than

adults I. another interpretation of Fig. 4 is thatthe time for development of adenomatousnodules following radiation exposure variesdirectly wmh age at exposure.

Nonthyroidal tumors

During the period 1985 through 1987, deathsattributable to cancer occurred in three exposedpersons. all from Utirik. The types of tumorswere: lung cancer, hepatoma. and meningiomaDuring the same period there were three cancer-related deaths in the unexposed population, thetumor t}~es being: colon carcinoma. hepatom~and myeiodysplastic syndrome.

Additional tumor diagnoses resulted fromclinical investigation initiated at the time ofmedical team \lsits. These included a case ofbreast carcinoma (detected by mammography)and a cas-e of colon carcinoma. both diagnosedin exposed LTtirikwomen. Both lesions weresur-gicallyresectedand have a high probability ofbeing cured. In addition, an epithelioma wasremoved from the skin of an exposed Rongelapwoman. the site of the lesion being in theapproximate area of a beta burn that developedsoon after the 1954 exposure. This type of lesion,

also termed basal cell carcinoma. is very com-mon in the United States and is not included inthe detailed cancer statistics published by theAmerican Cancer Society (Silverberg and Lub-era. 19871. However. its frequency in ,Makshal-lese is unknown.

The development of two cases of hepatomaamong the population served by the medicalteam requires comment. Two persons. one eachfrom the Utirik and the Comparison groups,died from this tumor during the period coveredby this report.To this number should be addedthe death of another Utirik man who died in1984 from complications of cirrhosis (Adams etal., 1985), for he, like one of the hepatomapatients. had hepatitis B surface antigendetected in his serum. Studies have demon-strated an association between hepatitis B sur-face antigenemia and hepatoma, cirrhosis, andchronic active hepatitis (Beasley et al., 1981).Early BNL observations revealed that infectionwith hepatitis B virus is nearly universal amongMarshallese, as it is among many tropical popu-lations, and that serological evidence of theinfection is common in childhood.

Autoimrnune thyroid iqjuw

Radiation-induced thyro]a hypofunction.

diagnosed in four[een exposed Rongelap indi-\lduais. was not found to be increased among

.Japanese .4-bomb survivors-. This difference

reflects the larger dose absorbed by thyroids of

the Marshallese. a consequence of ingestion of

radioiodines. The question arises as to whether

thyroid hypofunction in the exposed Marshal-]ese is a consequence not only of direct radiationinjury, but also of immunologic damage. Immu-

nologic studies by the Radiat]on Effects ResearchFoundation found that Japanese A-bomb survi-vors greater than fifteen years of age at expo-sure had a significant decreme in mixed lyre-phoc}le culture response that was inverselyrelated to radiation dose (Akiyama et al.. 19871,and lymphocyte responses to phytohemagglu-tinin decreased more rapldlv with age m per-sons who received more than 200 rad. However.the immunological responses of aging JapaneseA-bomb survivors do not appear to have beenaffected by radiation exposure (Bloom et al.,1988), nor does there appear to be an increase indiseases associated with autoimmunity in theexposed Japanese population.

Immunologic damage to the thyroid ismediated, in part, by circulating autoantibodiesthat are apparently cytotoxic. Antimicrosornalantibodies are important in the diagnosis ofautoimmune thyroid itis. a disease processcommonly progressing to hmothyroidism (Frey,19871. Antithyroglobulin anubodies are far lessspecific an indicaLor of thy~old autolmmune

disease. but are useful as a screening test. Hypo-thyroidism ISoften quite subtle and difficult todiagnose. and any marker that might identi~ apopulation at risk for subsequent hypothyroi-dism would be clinically useful. Therefore 231Marsh allese sera collected in March 1987 were

tested for the presence of antithyroglobulin andant]microsomal antibodies in the laboratory ofDr. Harry Maxon. Fifty-five sera were from theRongelap-exposed. 94 were from Utirik-,exposed,and 82 were from the Comparison group. Two

persons had data consistent with the diagnosis

of autoimmune thyroid disease (Table 4), and

both were in the Comparison group. One was a38-year-old woman who had Grave’s diseasewith hyperthyroidism diagnosed in 1980 thatwas treated with 131 I. Her serum containedboth types of antibodies in 1980 as well as in1987.The other person. a 32-year-old woman,had an antithyroglobulin antibody level of 35U/l. She has Sheehan’s syndrome, present since1975 following postpartum hemorrhage. In .addition, six persons had nondiagnostic butslightly elevated levels of a“ntithyroglobulinantibodies, two from Rongelap and four fromLTtirik. None have clinical evidence of aut~im.

mune thyroid disease, although three have hadthyroid lobectomies for benign nodules. The lackof evidence for an increase in autoimmune thy-roid disease among the exposed Marshallese isconsistent with the findings of Radiation EffectsResearch Foundation studies. In a 30-year fol-10WUPof persons less than 20 years of age at thetime of exposure to the atomic bomings inJapan, no difference was detected in the preval-

The prevalence of antimicrosomal anti-bodies also increases with age: two-thirds ofelderly persons with evidence of thyroid hypo-function had sign~]cant levels of antimicrosomalantibodies (Sawin et al.. 1985b).

MARSHALLESE

Thelatesomaticeffectsofexposureto ioniz-ing radiation have been equated with cancerinduction, the ultimate measure of those effectsbeing expressed in mortality. Since cancer mor-

tality from radiation exposure is low whencompared to naturally occurring cancer mortal-lty it is not surprising that there is no observedincrease in mortality among the radiation-exposed Marshallese. Nevertheless. much at-tention has been addressed to their cancer riskOn the other hand, limited attention has been “given to morbidity from nonmalignant disease,principally of the thyroid. as a late consequenceof radiation exposure, and yet these lesionshave been of great clinical importance (Table 5).

.& Thyroid surgeryTwenty-six (30 %) of the Rongelap group and

eighteen ( 1l%) of the Utirik group have hadsurgery for thyroid nodules that were ultimatelyfound to be benign. The types of thyroid nodulesfound in the exposed population since 1963 canbe grouped into cancers, adenomas. and ade-nomatous nodules. Cancers and adenomas areneoplasms. Adenomatous nodules, which, likeadenomas, are benign, are not propedy catego-rized as neoplasms. HistologicaUy, they’ arehyperplastic lesions. In the exposed populationboth benign nodules and thyroid hypofunctiondisplay a similar correlation with radiation doset Fig. 5), and, in contrast to thyroid cancer, ade-nomatous nodules have been very common (seeTable 3). Adenomatous nodules are rarely ofclinical significance, because they do not evolveinto carcinoma. Surgery is necessan only to

exclude that diagnosis. Nevertheless. the clinicalevaluation required to establish a diagnosis isassociated with its own morbidity. Prominent inthis morbidity is thyroid surgery itself, a proce-dure that requmes general anesthesia andresults in a cosmetic defect and the unavoidableremoval of some normal thyroid tissue.

B. Thyroid hypofunction, radiation-induced:Overt hypothyroidism was diagnosed in two

Rongelap boys who were infants at the time ofexposure (Sutow et al., 1965). In addition. sub-clinical hypothyroidism unrelated to thyroidsurgery was confirmed in twelve other Rongelappersons [Larsen et al., 1982). In 1987 a Utirikman was diagnosed as biochemically hypothy-roid. He was two years of age at the time ofexposure. and he is the first exposed personfrom Utirik to have this diagnosis.

C, Hypothyroidism, postsurgical:In 1972 to 1974 it was noted that 11 of 20

exposed persons from Rongelap who under-tvent surgenfor removal of thyroid nodules hadelevated levels of thyroid-stimulating hormonetTSH). Because this evidence of postsurgicalhypofunction was more frequent than expectedit was surmised that thyroid insufficiency mightbe developing in the exposed Rongelap popula-tion as a whole, rather than being limited to thetwo hypothyroid children diagnosed some tenyears earlier (Sutow et al., 1965). Such an eventwas likely to be clinically inapparent because allof that group had been placed on suppressivedoses of thyroxin since 1965 to prevent thyroidneoplasia. Therefore, after temporarily discon-tinuing thyroxin. a survey of thyroid functionwas undertaken. and twelve persons were found

(,]ency. Retrospectwe testing of six persons \vho

had th\Toid h}~ofunction a&er th}Toid surgeryreveaied the h>_pofunctlon had been presentearlier fLarsen et al., 1982).

The development of thyroid hypofunction m[he exposed indi~lduals continues to be a causefor concern. R’bile the routine use of suppressivedoses of thyroxm should render [his concernmoot. it was noted that. based on medical his-to~ or results of annual TSH testing, somewhatmore than forty percent of exposed personswho are supposed to be taking thyroxin haveevidence of irregular or noncompliance withthe prescribed medication regimen (Adams etal., 1983). It is desirable to minimtze 10SSof thy-roid tissue at surgery insofar as It is deemedclinically safe to do so: in fact. this has been thepractice of the thwoid surgery consultant to the\larshall Islands Medical Program for almost[wentv years.

Desp]te efforts to mitigate loss of thyroidtissue. however. there continues to be evidenceof an inordinantly high frequency of postsurgi-cal thyroid hypofunction among the exposedpopulation. Table 6 shows data obtained through1987 illustrating this point. An increase in fre-quency of postsurgical thyToid hypofunctionw]th increase in the 1954 thyroid radiation doseis apparent, even though all thyroid surgerypatients were advised to take thyroxin. How-ever. the data in Table 6 must represent a min-imum estimate of the prevalence of postsurgicalthyroid h-ypofunction. In contrast to the studyby Larsen et al. ( 19821, thyroxm was not pur-

poseiy discontinued before testing. Therefore.except for those relatively few instances in;vhich seiected individuals were asked not totake thyroxin for four to six weeks prior to thy-roglobulin testing or thyroid scanning, eievated

TSH levels were apparent only because of non-compliance. Some persons may have had nor-mal TSH Ieveis after surgery oniy because theyare adhering satisfactorily to the prescribed[hyroxin regimen.

It is unlikely that the differences in prevalenceof postsurgical thyroid hypofunction among thegroups resuit from different degrees of com-pliance in taking thyroxin after surgery, Furth-ermore, it is iikeiy that. on the average, theextent of resecIion of thyroid tissue was greater]n the unexposed persons undergoing thyroidsurgery than in exposed individuals because ofconcern that the iatter were more iikeiy to haveImpaired thyroid reserve. As Table 6 shows, thisconcern was weii-founded. “Mthough presentdata are without doubt quantitatively inaccu-rate, they are iikeiy to be qualitatively adequate.

The distinction between these data and thoseof Larsen et ai. ( 1982) is that. whereas thyroidhypofunction was found by the latter group toantedate thyroid surgery (as documented byretrospective analysis of stored sera collectedbefore institution of thyroxin suppression in theexposed Rongeiap group), the present datareveai an inordinantly high frequency of post-surgicai thyroid hypofunction in exposed per-sons with previously normal TSH Ieveis. TheImportance of this finding is that there appears

TObe slgnlficantlv dimmlshea th}’roid reser~’e mmany exposed persons. and. although this dim-inution ]s not apparent from routine TSH test-ing, it frequently may be made clinically signifi-

cant by thyroid surgery. The extent of theproblem cannot be accurately assessed with thedata at hand because ot’ the variability in com-pliance with the taking of the prescribed thy-roxin suppression, and because no clinicalbene!it would accrue to the exposed populationfrom discontinuing thyroxm for the purpose ofproving the point. Nevertheless. a 61!7, preval-ence of postsurgical thyroid hypofunction isreason for great concern in tiew of the highfrequency of benign thyroid nodules in theexposed population.D. Postsurgical hypopsrathyroidism:

In two thyroid surgery patients transientpostsu rgical hypocaicemia was observed. How-ever. two other Rongelap women developedchronic hypoparath.moidism requiring replace-ment therapy since undergoing thyroid surgery.In one the deficiency was diagnosed postopera-tively and has not resolved. In the other thediagnosis was first made. twenty years followingsurgexy. Both surgeries were performed onGuam during the early years of the medical pro-gram. Postsurgical hypoparathyroldism is notan unusual complication of extensive thyroidsurgery, occurring in up to 20Xof patients. How-ever, in experienced hands the frequency ofpostsurglcal hypoparath.yroidism is much lower.

E. Laryngeal neme iqjuwOne Rongelap man has a mild but definite

impairment in speech resulting from recurrentlaryngeal nerve injury, a well-known complica-tion of thyroid surgety. This is not a commoncomplication, occurring in perhaps l!% ofpatients. i% with postsurgical hypoparathyroi-dism, its frequency depends greatly on the expe-rience of the surgeon and the extent of thesurgery.F. Pituit.my tumor formation:

Two women exposed as young children, onefrom Rongelap and one from Utirik. have deve-loped pituitary tumors. These tumors are usu-ally benign, causing disease. in part, because oftheir expansion inside a rigid structure. There isno known direct association between radiationexposure and development of pituitary tumor,but there are reasons to suspect that pituitawtumor formation may be a consequence of thy-roid injury (Adams et al.. 1984).

In summary. hypothyroidism and subclinicalthyroid hypothnction. benign thyroid noduleformation. thWoid surgew with its attendantrisks and complications. an excessive preva-lence of thyroid hypofunction after thyroidsurgery, and possibly pituitary tumors can beconsidered adverse delayed consequences ofradiation inju~ in the exposed Marshallese. Thetally comes to 85 morbid events in 253 persons.In contrast. the only evidence for a “stochastic”effect of radiation exposure has been anincrease in thyroid cancers in the Rongelappopulation, none of whom yet have evidence ofresidual disease. While several nonthyroidalcancers known to be inducible in humans “byexternal ionizing radiation have been docu-mented in the exposed population, similarcancers have occurred in the unexposed Com-parison population of Marshallese. Therefore,one may conclude that in the Marsh allese expe-rience the delayed expression of nonmalignantmorbidity due to irradiation has indeed beengreat and far exceeds that of malignant disease.

REVIEW OF CANCER IN THECOMPARISON POPULATIONIn earlier BNL publications neoplasms of the

exposed population were compared to those ofan unexposed “Comparison” population with asimilar age and sex distribution. However, since,the last report. which brought the period ofmedical coverageup to December 3 lst, 1984,concerns have been voiced about present-daysafety of habitation on Rongelap island. Ananalysis of the current radiation risk of Ron-gelap habitation is not a function of the MarshallIslands Medical Program. which is a clinical pro-gram devoted to aspects of health care for per-sons acutely exposed to radioactive fallout in1954. Nevertheless, medical information col-lected over many years concerning the unex-posed Rongelap people has been requested bydifferent groups who are involved in assessingthat risk. To assist them and others who maywish to review the medical experience of theComparison population, a summary of diag-noses of neoplastic disease is presented here. Itis essential to realize that whatever radiationrisk exists today on Rongelap is quite distinctfrom that incurred by 86 Rongelap inhabitantsand 167 Utirik inhabitants during the two-dayexposure to Bravo fallout in 1954. The reasonsfor this statement are given below.

5004111 17

The selection of the Comparison woup beganin1957at Majuro when the group was initiated~rlth .96 individuals matched approximately forsex and age with the exposed group of 86 indl-\~duals, }Iembers of the Comparison group wereexammed periodically thereafter at Rongelap orelsewhere along with members of the exposedRongeiap population. During 1958-59, after thereturn to Rongelap island. the number of per-sons actively enrolled in the Comparison groupwas increased to about 150. During the followingyears up to 1974, another 31 persons wereadded. In 1974-76, to make up for more personslost to followup or deceased. another 32 personswere added. No additions to the roster havebeen made since that time. When all enrolleesare tallied, including those who have discon-

tinued their participation in the annuai medicalexammations, 227 persons have been exammed

at one time or another as part of the Compari-

son group. Although some of the group were lost

to followup, there were 63 deaths recorded

through 1987. Some deaths may have occurred

In those lost to followup that were not brought

to the attention of the Marshall Islands Medical

Program. Furthermore, the death rate in subse-quently added subgroups may not be the sameas that for persons in 1957. There IS no way todetermine if there is any bias introduced intomonality statistics as a consequence of theseevents which were beyond the control of theprogram. However. two points can be made.First. since it is cancer mortality which is specif-ically in question. cancer deaths can be expres-sed in terms of total known deaths. thereby con-trolling to some extent for uncertainties in thedetermination of total deaths. Therefore, on thebasis of information made available to the Mar-shall Islands Medical Program. 8 of the 63known deaths ( 13!7,) may have been due tomalignant disease. In the United States cancermortality accounts for 22’% of total mortality(Silverberg and Lubera, 1987), and in theexposed Rongeiap group it accounts for 19X,oftotal mortality (5 of 26 deaths). Second, cancerdeaths can be expressed in personl years ofobsenation, thereby controlling somewhat forpersons lost to followup. When this is done thecancer death rate for the 33-year observationperiod is 171/100,000(8 possible cancer deathsin 4669 person lyears) for the Comparisongroup overali and 187/ 100,000 (4 possiblecancer deaths in 2136 personl years) for the 86

persons in the original 1957 Comparison group.The slmilarityof these numbers does not suggestthe introduction of bias in death rates in subse-quent additions in the Comparison population.For the Rongelap exposed population. \vhichwas statistically similar in age and sex distribu-tion to the Comparison group when evaluated in1982 (Adams et al.. 1983), this number is234/ 100.000 ( 5 possible cancer deaths in 2139personi years). The confirmed or presumptivecancer diagnoses in the Comparison group aregiven in Table 7, along with cancer deaths in theexposed Rongelap population.

Table 8 contrasts the distribution of possiblecancer deaths in the Comparison group accord-ing to years of residence on Rongelap with thatoft he exposed population. One of the eight per-sons dying of possible cancer in the Comparison

grouP WaS never known to be present on theisland. Furthermore, six of the eight spent only ashort time on Rongelap. However. for those sixthat short time lay between 1958 and 1961, aperiod when residual radioactivity would havebeen higher than in subsequent years. Onehundred fifty-one persons in the Comparisonpopulation were known to be on Rongelap atsome time between 1958 and 1961. Of the sixthat ultimately died of possible cancer, fourwere among forty-two who were not on Ron-gelap after 1961, whereas two were among theone hundred-and-nine that were seen on Ron-geiap at a later date (Table 9). It is a statisticaloddity that even the latter two individuals werefound on Rongelap only once after 1961.

There are several points that are relevant forthose who would apply an epidem]olog]c analy-sis to these data

1. Since the Marshall Islands Medical Programhas not maintained a year-round medical pres-ence on the different atoUs where examineesmay be found. causes of death were obtained inmany instances from records and verbalaccounts of health aides and family membersliving on those atolls and from records anddeath certflcates at the Ebeye and Majuro hos-pitals. Autopsies are rarely performed in theMarshall Islands.

2. Of the eight deaths that clinically may havebeen cancer-related. confirmation by tissuediagnosis is available in only four. In the exposedRongelap population only three of the fivedeaths attributed to cancer were confirmed.

Table 7 presents Iimlted information relevant to

[he diagnosis of the cancers m the Compatuson

group+ but all 8 cases have been desmbed in:reater detali in this or earlier B!NLreports.

3. The mosr frequent lethal cancers m the Uni-ted States are lung, breast. colon and leukemia. -Iymphoma.

4. Areas where health care is limited often haveincreased mortality from noncancerous disease.and an increase in cancer incidence has been\tiewed as e]~dence of improved overall health ofsome populations because it reflects improve-ments in longevity.

5. Table 7 lists only cieaths that might have beenrelated to cancer. There have been two cases ofthyroid cancer that have been diagnosed. Thethyroid cancers, discussed elsewhere In thisreport, have not been a cause of death. and at

[he present time there is noevidenceof residuaidisease in either of the thyroid cancer patients.

6. In attempting to determine whether therehas been an increase in cancer deaths in eitherthe exposed or Comparison poptdation oneshould note a Radiation Effects Research Foun-dation report on the Japanese exposed to atom]cbombing. From 1950 to 1985. there had been.5936 cancer deaths among 75991 persons in theLSS (Life Span Study) cohort. Three hundredand forty of the cancer deaths ( 6’Lof the totalcancer deaths) are thought to be attributable tothe 1945 radiation exposure (Preston andPierce. 1988). The small size of the exposed andComparison Marshallese groups, the smallernumber of cancer deaths, and naturally occur-ring fluctuations in disease incidence will makestatistical detection of any excess cancer mor-tality Impossible in these populations.
