Microinvasive and early invasive cervical cancer

IEO 2014
Standard treatment for invasive cervical
cancer traditionally includes radical
hysterectomy and pelvic limphoadenectomy.
The rationale of the treatment is the
extirpation of the tumour, with clear
margins, and of the lumphatic vessels.
![Page 3: 4 dr mario sideri m k](https://reader033.vdocuments.mx/reader033/viewer/2022052600/557d1a78d8b42a6e4f8b4b3d/html5/thumbnails/3.jpg)
IEO 2014
There are early tumours with a small
volume in wihich the removal of the
parametrium can be omitted;
in addition in some instances the tumour
volume can be so small that the risk of
lymphnode metastasis is limited, and
pelvic lymphadenectomy can also be
omitted
![Page 4: 4 dr mario sideri m k](https://reader033.vdocuments.mx/reader033/viewer/2022052600/557d1a78d8b42a6e4f8b4b3d/html5/thumbnails/4.jpg)
IEO 2014
Volume is expressed as lenght and
depth of infiltration of the neoplasia
Categories where conservative approach
is feasible:
IA1 3 mm in depth, 7 mm in lenght, no LVSI
IA2 5 mm in depth, 7 mm in lenght, neg. nodes
IB1< 2 cm in largest diameter neg. nodes
IB1 >2<3 cm in largest diameter, neg. nodes

IEO 2014
Volume is expressed as lenght and
depth of infiltration of the neoplasia
The measures that define “micoinvasive”
cervical cancer can only be obtained from a
surgical specimen containing the whole lesion.
Colposcopy is critical to help excise all the
lesion in order to define the diagnosis
![Page 6: 4 dr mario sideri m k](https://reader033.vdocuments.mx/reader033/viewer/2022052600/557d1a78d8b42a6e4f8b4b3d/html5/thumbnails/6.jpg)
IEO 2014
Main reasons for cervical cancer
declining mortality:
• Cervical cancer screening programs
• Intraepithelial lesions (CIN) detection
• CIN therapy

Conservative therapy
Accurate pre-surgical
evaluation of the lesion

Key role in:
• Grading
• Size definition of the lesion
• Identification of early invasive
disease

Failure after excisional CIN
treatment
Incorrect assessment of the lesion

IEO 2014
END POINT
To verify the predictive value of
multiple tests in CIN pre-surgical
assessment
• avoid under/over treatment
• schedule proper follow-up
• prevent risk for disease persistence

Conclusions 1No Gold Standard in diagnosis !!!
• LG SIL on Pap smear or punch biopsy
may hide a HG SIL or Cancer
• Punch biopsy may be an inadequate end
point by which to judge the severity of the
lesion
