Overview of docetaxel (Taxotere)/cisplatin combination in non-small cell lung cancer

Cisplatin-based chemotherapy is effective in non-small cell lung cancer (NSCLC), although it prolongs survival only modestly. Single-agent docetaxel (Taxotere; Rhône-Poulenc Rorer, Antony, France) is highly active against NSCLC. The activity and tolerability of two docetaxel/ cisplatin regimens were therefore investigated in two multicenter phase II studies, one in Australia and one in France. Chemotherapy-naive patients with inoperable NSCLC received either docetaxel 75 mg/m2 on day 1 plus cisplatin 75 mg/m2 3 weekly (n = 47; Australian study) or docetaxel 75 mg/m2 on day 1 plus cisplatin 100 mg/m2 every 3 weeks for three cycles then every 6 weeks (n = 51; French study). The majority of the population (74%) had metastatic disease. Seventy-eight patients were evaluable for efficacy. Overall response rates were 36% (95% confidence interval, 25 to 47) in all evaluable patients and 34% in patients with metastases. Median duration of response was 6 months, with a 4-month median time to progression. Median survival time was 9 months, with a 1-year survival rate of 34%. A median of four (range, one to nine) treatment cycles were administered. Febrile neutropenia occurred in 14% of patients. Severe infection, which occurred in less than 7% of patients, led to two toxic deaths. Other severe toxicities were rare, with severe stomatitis and severe neurosensory side effects reported in 2% and 1%, respectively, of treated patients. No severe fluid retention occurred. Docetaxel/cisplatin, administered as two different schedules, is well tolerated and exhibits efficacy in the range of the most established combinations in the treatment of advanced NSCLC.
