title: Combined modality treatment of short duration in small cell lung cancer.
abstract: Fifty-seven patients with small cell lung cancer (SCLC) (limited disease = LD in 23, extensive disease = ED in 34) received the combination of CCNU, cyclophosphamide, vincristine and methotrexate (CCOM). A mean number of only 6 (range 1-17) courses of chemotherapy were given. All LD patients received consolidation locoregional radiation (30 Gy) after two courses of chemotherapy. A complete response (CR) was obtained in 61% of LD and 12% of ED patients, and a partial response in 22 and 35% respectively. Median survival was 54 and 34 weeks for LD and ED respectively. Five LD patients survived more than 2 yr, three of them remaining disease-free 4 yr after the cessation of treatment. A subset of 12 LD patients achieving a CR after two courses of chemotherapy was randomized to receive maintenance chemotherapy or observation only after the consolidation radiotherapy. In this small-sized randomized trial maintenance treatment showed a significant decrease of the patients' quality of survival compared to no maintenance treatment. We conclude that combined modality treatment of short duration proved effective in SCLC. Future randomized studies are necessary to show whether prolonged chemotherapy has a meaningful impact on survival, or otherwise the resulting morbidity will plead against it.
