Abstract

This randomized study of previously untreated patients with extensive disease small cell lung cancer was designed (a) to compare the survival of patients treated with either effective standard chemotherapy or an investigational anti-cancer drug as initial therapy and (b) to evaluate response rates and toxic effects of such therapies. One hundred and thirty-five patients were randomly assigned to receive as initial therapy, either the standard CAV regimen - cyclophosphamide (1000 mg/m2), doxorubicin (50 mg/m2) and vincristine (1.4 mg/m2) every 3 weeks - or the phase II drugs ifosfamide (1.5 gm/m2/days 1-5) with mesna (300 mg/m2) dose at 0, 4 and 8 h after IV daily ifosfamide every 3 weeks or teniposide (60 mg/m2/days 1-5) every 3 weeks. Nonresponders received salvage chemotherapy-etoposide (120 mg/m2 on days 1, 2 and 3) and cisplatin (60 mg/m2 on day 1), repeated every 3 weeks. Among the 46 patients on CAV, there were two complete and 24 partial responses (56%). Among the 43 patients on ifosfamide, there were three complete and 18 partial responses (49%), while among the 46 patients on teniposide, there were two complete and 18 partial responses (43%). Eighty-three of the patients proceeded onto salvage regimen, of which 81 were analyzable for response and toxicity. Among the 81 patients who continued on salvage therapy and were evaluable for response, the overall best response rate was 61% for CAV+salvage, 54% for ifosfamide+salvage, and 53% for teniposide+salvage. These rates were not significantly different (P=0.962). Of the 135 analyzable patients, 130 (96%) have died. The estimated median survival time was 42 weeks for CAV patients, 43 weeks for ifosfamide, and 38 weeks for teniposide. Seven patients survived longer than 2 years (four on CAV, one on ifosfamide and two on teniposide). There were 29 life-threatening complications to the induction regimen (22 (48%) on CAV, four (9%) on ifosfamide and three (7%) on teniposide) and seven lethal complications (two on CAV, four on ifosfamide and one on teniposide). The treatments were significantly different with respect to the overall degree of toxicity (P<0.0001) with CAV being more toxic. The data of this study, like the previous ECOG study suggests that the administration of a new agent followed by effective salvage chemotherapy in the treatment of extensive disease small cell lung cancer may have no adverse effect on survival.
