Abstract

AIM: To investigate the development of a safer chemotherapeutic regimen with better compliance, a total of 67 patients were enrolled as a single arm in a two-stage multi-center phase II study.

METHODS: The patients received chemotherapy with carboplatin (CBDCA) with an area under the curve (AUC) of 5, and docetaxel (DTX) at 60 mg/m2 tri-weekly for three cycles after surgery. The primary endpoint of this study was compliance, while the secondary endpoints were the adverse events (AE) and recurrence-free survival (RFS).

RESULTS: Sixty-one patients were treated in this study arm. The patients were 43 males and 18 females, with a median age of 64.6 years. Fifty-one patients (83.6%) completed all three cycles of therapy. The presence of Grade 3 and 4 neutropenia was noted in 25% and 66% of the patients, respectively. The non-hematological AE were less frequently reported, and no treatment-related death was registered. The two-year RFS and OS rates of the 61 patients were 69.8% and 88.3%, respectively.

CONCLUSION: A tri-weekly schedule of CBDCA and DTX as adjuvant chemotherapy showed a favorable feasibility.

Core tip: Adjuvant chemotherapy with a tri-weekly schedule of carboplatin and docetaxel was feasible in Japanese non-small cell lung cancer patients. In clinical practice, this regimen represents a potential treatment option that may be superior to other regimens. The main limitation associated with this study is the small number of patients enrolled. Therefore, it is important to employ a reference arm for any future randomized clinical trials evaluating this treatment regimen.
