Adjuvant chemotherapy for completely resected stage III non-small-cell lung cancer. Results of a randomized prospective study. The Japan Clinical Oncology Group.

Two hundred nine patients with completely resected stage III non-small-cell lung cancer were randomized to receive postoperative cisplatin and vindesine chemotherapy or no further treatment. Before randomization, patients were stratified by the histologic characteristics of their tumors (squamous versus nonsquamous cell carcinoma). Prognostic variables such as histology, performance status, extent of operation, and tumor and nodal status of the eligible patients in chemotherapy (n = 90) and control groups (n = 91) were equally distributed. There was no statistically significant difference in disease-free and overall survival between the two groups. The 3-year disease-free survivals of the chemotherapy and control groups were 37% and 42%, respectively. The median survival times (5-year survival) were 31 months (35%) in the chemotherapy group and 37 months (41%) in the control group. These was no different pattern in the first site of recurrence (local versus systemic) between the two groups. This study failed to demonstrate the therapeutic benefits of postoperative cisplatin and vindesine chemotherapy.
