71 was 7 months. Four out of l0 partial respon- ders failed in the C.N.S. and 6/10 includ+ ing 3 patients from C.R. failed in the chest in group I. Separately in groups II (23/33) and III (23/32) 70% failed in the chest and 25/65 failed in the C.N.S. in both groups. Four out of 17 in group II failed in bone as against 15/32 in group III. Analysis of data revealed that 75% of failures occurred within 12 months irrespective of the site of failures and the median survival following the occurran- ce of metastasis was 12 weeks and was in- dependent of the site of failure.

The Long Survival in Unresectable Small Cell Lung Cancer. Soresi, E., Borghini, U., Harari, S., DiNoia, C., LoCicero, S., Scoccia, S. Department of Pneumonology, E.O. Niguarda, Milan, Italy

1436 patients (pts) with unresectable lung cancer were registered in the ambu- latory of Pneumology Department of E.O.

Niguarda, from 1977 to 1981. Small cell lung cancer (SCLC) was observed

in 201 (14%) of these pts: 114 pts (56.7%) showed extensive dieease (ED) and 87 pts (43.3%) showed limited disease (LD). All LD pts and 47 (41%) only of ED pts underwent at least two periods of ¢hemotherapy (CT).

At first, only MACC trial was administe- red during the first three years, successively, in agreement with a trial of Oncological Divi- sion of S. Carlo Hospital of Milan, CAV alter- nate with CMC plus radiotherapy was carried out.

Conclusions: With the first trial the me- dian survival rate for LD pts was 11,2 months and 6,8 months for ED pts while with the second trial it was 11,4 and 7,9 moths for LD and ED pts respectively.

8 long survival (LS > 30 months) were ob- tained in the follow up of 87 LD pts with SCLC.

No significant-difference was noted eva- luating the results of the two CT trends.

At present 31,40,44,52 and 54 are respec- tively the months of survival in the 5 LS pts alive and in free disease.
