    Abstract:
    BACKGROUND: To assess whether the addition of cisplatin (100 mg/m(2) administered intravenously on Day 1) to CDE (cyclophosphamide [1000 mg/m(2) on Day 1], doxorubicin [45 mg/m(2) on Day 1], and etoposide [150 mg/m(2) on Days 1 and 2] combination is useful in the treatment of patients with small cell lung carcinoma (SCLC). METHODS: In a multicenter clinical trial, 457 patients were randomized from May 1988 to March 1993 to receive either CDE (n = 228) or cisplatin-CDE (PCDE, n = 229) chemotherapy every 4 weeks for 6 cycles. As patients with limited SCLC were included in a concomitant trial assessing thoracic radiotherapy, the current study mainly included patients with extensive stage (79%) or limited stage disease and a contraindication for thoracic radiotherapy. RESULTS: The objective response rate was higher in the cisplatin-CDE group (72%) than in the CDE group (53%) (P = 0.0001). The median overall survival was similar for the groups that received CDE (266 days) and PCDE (271 days) (P = 0.93, log rank test). A higher fatal neutropenia rate was observed in the PCDE group (n = 23) than in the CDE group (n = 4) (P < 0.001, log rank test), mainly for patients with extensive disease (n = 26; P = 0.015, log rank test). CONCLUSIONS: The addition of cisplatin to a CDE regimen is toxic to patients with extensive SCLC and does not improve overall survival. The PCDE combination must be avoided for patients with extensive SCLC; CDE or cisplatin-etoposide combinations remain standard chemotherapy for these patients. The PCDE combination associated with granulocyte-colony stimulating factors could only be assessed in patients with good prognoses.
