Small cell lung cancer. State-of-the-art therapy 1994.
In the United States, small cell lung cancer (SCLC) accounts for about 20% of all cases of lung cancer. Without treatment, tumor progression in patients with SCLC is rapid, with a median survival of 2 to 4 months. Modern chemotherapy has yielded multifold increases in median survival, but only minimal improvements have occurred over the last decade. Combination chemotherapy with etoposide/cisplatin prolongs survival, especially in patients with limited disease. In patients at high risk of toxicity from standard combination chemotherapy, single-agent chemotherapy may have a viable role, but whether its efficacy is comparable to combination regimens must be established in clinical trials. Clearly, new, more effective drugs will be required for any major improvements in the treatment of SCLC. Combined-modality therapy employing chemotherapy and chest irradiation appears to produce excellent cytotoxic effects and is relatively well tolerated in patients with limited disease. A recent meta-analysis of 13 randomized trials showed a modest but significant 14% reduction in the relative mortality rate of patients receiving chemotherapy/chest irradiation vs those receiving chemotherapy alone. Surgery as sole treatment can produce cures in highly selected patients with limited disease and can reduce the rate of local recurrence. The use of surgery after definitive treatment remains experimental and should not be considered other than in controlled clinical trials.
