Fractionated dose of cisplatin (CDDP) and vinorelbine (VNB) chemotherapy for elderly patients with advanced non-small cell lung cancer: phase II trial.

BACKGROUND

The incidence of non-small cell lung cancer (NSCLC) is increasing among the elderly representing about 30% of NSCLC patients over 70 years old. The aim of this study was to evaluate the response, survival and tolerability of a modified schedule with cisplatin-vinorelbine in elderly patients with advanced NSCLC.

METHODS

Between November 2001 and March 2003, 30 patients were included into the study. Median age was 73 (range 70-77). Male/female 27/3 (90%/10%); 60% of patients were stage IV at diagnosis and only one patient presented with brain metastasis. Treatment consisted of cisplatin 30 mg/m(2) on days 1 and 8, and vinorelbine 25 mg/m(2) on days 1 and 8 every 21 days.

RESULTS

A total of 120 cycles were administered with a median of four cycles per patient. The most relevant WHO toxicities were: neutropenia grade 3 in 6 (20%) patients and grade 4 in 13 (43%) patients. There were three (10%) treatment-related deaths: two caused by neutropenic fever and one due to acute pulmonary oedema. No other relevant hematological and non-hematological toxicities occurred. By intention-to-treat analysis, 10 patients (33%) showed stable disease and 10 patients (33%) showed a partial response while 10 patients (33%) showed treatment failure. Median survival time was 7.4 months; 1-year survival was 36.6% and median time to progression was 5.14 months.

CONCLUSION

At this dose and schedule, the combination of vinorelbine and cisplatin obtained a response rate and survival comparable to the most active regimens. Non-hematologic toxicity was mild while neutropenia was the most relevant toxicity.
