[Estimation of preoperative induction chemoradiotherapy effectiveness for non small-cell lung cancer].

We have performed the clinical evaluations of preoperative induction chemoradiotherapy (CRTx) for 25 patients with non small-cell lung cancer (male: 19, female: 6, mean age: 66.4-year-old). The clinical stages of these patients were IIA: 1, IIB: 7, IIIA: 14, and IIIB: 3, respectively.
