title: The role of carboplatin in the treatment of small-cell lung cancer.
abstract: Lung cancer is the leading cause of death due to cancer in the United States, and approximately 178,100 new cases were estimated to occur last year. Small-cell lung cancer (SCLC) accounts for approximately 17% to 25% of all lung cancers. Due to its aggressive nature and rapid proliferation rate, small-cell lung cancer is usually widespread at diagnosis. Therefore, chemotherapy is the cornerstone of therapy for this disease. Cisplatin (Platinol) is an active chemotherapeutic agent used to treat small-cell lung cancer, but its toxicity, including nausea and vomiting, nephrotoxicity, neurotoxicity, and ototoxicity, has led to the investigation of combination regimens with different toxicity profiles. Carboplatin (Paraplatin), a derivative of cisplatin, has far less nonhematologic toxicity, although myelosuppression may be slightly greater than that observed with cisplatin. The reduced toxicity and equivalent efficacy of carboplatin have resulted in the increased use of carboplatin-based regimens to treat small-cell lung cancer. Phase I and II trials of carboplatin as single-agent treatment for small-cell lung cancer resulted in overall response rates of approximately 60% for previously untreated patients and 17% for those who had received prior therapy. New combination chemotherapy regimens that include carboplatin may improve survival in patients with small-cell lung cancer and potentially cure those patients with limited disease. Further investigation of carboplatin and other new agents is warranted.
