[Surgical results for second primary lung cancer].
Of 897 patients who underwent operation for lung cancer between April 1996 and March 2010, 57 patients underwent pulmonary resection for 2nd primary lung cancer. There were 44 men and 13 women. The average age at the 2nd operation was 71. The initial pulmonary resection was lobectomy in 49 patients, segmentectomy in 4 and wedge resection in 4. The 2nd pulmonary resection was lobectomy in 10 patients, segmentectomy in 12 and wedge resection in 35. Preoperative stage of the 2nd primary lung cancer was IA in 43, IB in 13 and IIB in 1. Postoperative stage was IA in 38, IB in 10, IIA in 1, IIB in 3, IIIA in 2 and IIIB in 3. Surgical complications occurred in 4, but there were no perioperative deaths. The 5-year survival rate for 2nd primary lung cancers was 59.9%. The 5-year survival rate for patients treated with wedge resection was 71.1%. The 5-year survival rate of the patients with p-stage IA was 72.7%, and that for patients with p-stage IB or more advanced diseases was 32.9%. We conclude that an aggressive surgical approach for a 2nd primary lung cancer is effective and is linked with good outcome if the tumor is detected at stage IA, when the possible cure by performing wedge resection is promissing.
