✦ Synopsis

In a randomized study 145 patients with extensive small cell carcinoma of the lung were treated with chemotherapy alone (Cytoxan, CCNU, methotrexate) or with the same drug regimen and with radiation therapy to the brain, chest, and abdomen. One hundred eighteen of these patients were evaluable. Those patients receiving radiation had a better response rate (55% vs 31 %, P = .016) but significantly greater toxicity. There was no signficant difference in rates of complete response (7% vs 8%) or in survival (median 18.4 vs 15.3 weeks) between the two groups overall. The median survival of those patients with a partial resonse to therapy was 18 weeks; for those achieving a complete response it was 46 weeks. However, a clear difference in survival comparing responders with nonresponders was evident only for patients who were assigned to chemotherapy alone. Partial regressions have little, if any, correlation with improvement in survival. Therapy in this disease must be oriented toward inducing complete response.
