Abstract
We report a 42-year-old male case with lung cancer effectively treated by chemother-apy and the subsequent curative operation. He was diagnosed as epidermoid carcinoma of riht upper bronchus of clinical stage IQ A (cT3N2MO). After 3 courses of CMV chom-otherapy, the tumor disappeared on chest roentgenography and chest CT findings, and the right upper lobectomy with bronchoplasty was done. Pathological stage was I (pT1NOMO) and T factor was within the category of hilar early lung cancer. The efficacy rates of CMV chemotherapy against non-small cell lung cancer are reported over 40%, higher curative operation rates will be expected for stage IIIA non-small cell lung cancer with neo-adjuvant chemotherapy.
