Abstract
Purpose
Adjuvant vinorelbine and cisplatin chemotherapy is recognized as a standard regimen for patients with completely resected stage II and III non-small cell lung cancer (NSCLC). However, efficacy of adjuvant chemotherapy in Japanese phase III trials with cisplatin-containing regimen has been controversial, and data are limited on the long-term outcome of adjuvant vinorelbine and cisplatin chemotherapy for NSCLC patients.
Methods
This was a single-arm phase II study in patients with completely resected pathological stage II or III NSCLC, who had not received prior chemotherapy or radiotherapy. Patients received 4 cycles of vinorelbine [25 mg/m2 of body surface area (BSA)] and cisplatin (40 mg/m2 of BSA) on days 1 and 8, every 4 weeks. Primary end point was the 3-year relapse-free survival; secondary end points were overall survival and safety.
Results
Between December 2006 and January 2011, 60 patients (40 men and 20 women, median age 64 years) were enrolled; all patients were evaluable for survival and safety. Three-year relapse-free survival rate was 55.0 % (95 % confidence interval 42.4–67.6 %). Three- and five-year overall survival rates were 83.3 and 77.8 %, respectively. There were no chemotherapy-related deaths, and adverse effects were acceptable.
Conclusions
Adjuvant vinorelbine and cisplatin chemotherapy was safe and showed a valid relapse-free survival rate. This regimen could be used as a standard regimen and deserves to be a control arm of trials on adjuvant chemotherapy in the Japanese NSCLC patient population.
