Post-operative adjuvant chemotherapy(POAC)combining cisplatin(CDDP)and vinorelbine(VNR)for non-small cell lung cancer(NSCLC)patients is considered as a standard regimen. However, some Japanese investigators point out the toxic profile of this regimen in the practice settings. Thus, five consecutive patients with mean age of 61.6 years old were treated to evaluate the feasibility of this regimen among Japanese patients. Three male and 2 female patients were enrolled, with post-operative stage of IIB/IIIA/IIIB in 1/2/2 patients, respectively. CDDP was administered on day 1 at 80 mg/m(2), and VNR on days 1 and 8 at 25 mg/m(2) intravenously, every 21 days. The regimen was aimed to complete 4 cycles, and 4 patients have completed the treatment without reducing the doses. Average treatment interval was 23 days. Four patients experienced grade(Gr)4 neutropenia, and 1 patient had Gr 3 liver damage. Other mild toxicities included Gr 1 nausea/vomiting in all patients, and Gr 1 GFR reduction in 3 patients. Combination of CDDP and VNR seems to be tolerable in terms of POAC, with relatively mild toxicity profile similar to the previous reports.
