Background: About 30% of patients with non-small cell lung cancer (NSCLC) have locally advanced cancer (stage IIIA or IIIB) at the time of presentation. Many institutions have reported treatment with preoperative chemoradiotherapy (PCRT) followed by curative resection in patients with stage III NSCLC, but the optimal therapeutic protocol for this group has not been established. Patients and Methods: Nineteen patients with stage III NSCLC were treated with PCRT, followed by surgery at the Hamanomachi Hospital, Fukuoka, Japan from May 2000 to November 2011. We evaluated the effectiveness of PCRT for inducing downstaging using mainly three chemoradiotherapy regimens; cisplatin plus Tegafur-Gimeracil-Oteracil Potassium (S-1), cisplatin plus Tegafur-Uracil (UFT), or 1,1'cyclobutanedicarboxylate (Carboplatin, CBDCA) plus paclitaxel, with concurrent radiation therapy in 19 patients with stage III NSCLC. Results: The overall 5-year survival rate was 57.1%, which is higher than the average survival rate for patients with stage III NSCLC in Japan. Among the regimens used, only cisplatin plus S-1 with concurrent radiation therapy significantly induced downstaging. There was a significant difference in survival time between the downstaged and non-downstaged groups. However, there was no significant difference in survival time between the S-1 plus cisplatin group and the other groups combined, because of the short observation period for the S-1 plus cisplatin group. Conclusion: PCRT using cisplatin plus S-1 with concurrent radiation therapy is useful for inducing downstaging in patients with locally advanced stage III NSCLC.
