abstract...
Seventy-one previously untreated patients with small cell lung
cancer (SCLC) received a combination of VP-16, vincristine,
doxorubicin (Adriamycin), and cyclophosphamide (EVAC) repeated
every three weeks. Limited-disease (LD) patients and
extensive-disease (ED) patients achieving a complete response
(CR) or partial response (PR) after four to six cycles of EVAC
received 4,000 rads over four weeks whole-brain radiotherapy
(RT) and 5,000 rads over five weeks RT to the original
pulmonary primary and mediastinum. ED patients with persisting
disease outside the chest after six cycles of EVAC continued
chemotherapy and did not receive RT. After RT was completed,
EVAC was continued for a total treatment duration of 24
months. Of 65 patients evaluable for response 76% (25 of 33)
of LD patients and 34% (11 of 32) of ED patients achieved a CR
prior to RT; two additional ED patients achieved a CR after
RT. Median survival for all 71 patients was 48 weeks (range,
one to 207 weeks); median survival for 33 LD patients was 92
weeks and for 38 ED patients it was 36 weeks. Nine of 25 LD
patients and 10 of 13 ED patients have relapsed from CR. The
EVAC-RT protocol is promising in view of the high CR rate and
long remission duration achieved, especially among patients
with LD.
