Retrospective Review of Chemotherapy for Small Cell Lung Cancer in the Elderly: Does the End Justify the Means?

Between 1978 and 1983, 72 patients aged 70 years or older (median 72, range 70-80) were treated for biopsy-proven, small cell lung cancer (SCLC). Intercurrent disorders were common, including ischaemic heart disease, peripheral vascular disease, chronic airflow limitation and second malignancies. 26 patients (36%) had limited extent of disease, and 46 (64%) had extensive disease. "Intensive" chemotherapy incorporating vincristine, cyclophosphamide and doxorubicin (OCA regimen) was administered to 32 patients [complete response (CR) + partial response (PR) = 84%]; less rigorous regimens (e.g. single agent chemotherapy, planned dose reductions, radiotherapy only) were used in 34 cases (CR + PR = 52%); and 6 received no active treatment. In the intensively treated group, there were 3 treatment-related deaths and 26 episodes of WHO grade 3-4 toxicity. In the less intensively treated group, there were no treatment-induced deaths and only 1 episode of severe toxicity. The overall median survival was 25 weeks (36 weeks for intensive treatment, 16 weeks with less intense treatment). For patients with limited disease only, the median survival in each group was 43 and 26 weeks, respectively. Intensive treatment for elderly patients with small cell lung cancer is associated with substantially increased toxicity and higher response rates than for gentle treatment, but without a major survival benefit.
