[Lung cancer in Japan: analysis of lung cancer registry cases resected in 2004].

The Japan Lung Cancer Society, Japanese Association for Chest Surgery, and Japanese Respiratory Society jointly established the Japanese Joint Committee for Lung Cancer Registration. In 2010, analyses of 11,663 cases of lung cancer that underwent surgical resection in 2004 were performed, then the findings were registered and collected for analysis by the committee. The survival rate for all cases was 69.6%, while the 5-year survival rate in males (n = 7.369) was 63.0% and 80.9% in females (n = 4,294). The 5-year survival rates by c-stage (UICC Ver. 6 and Ver. 7) were as follow: IA (n = 6,295, 6,295), 82.0% and 82.0%; IB (n = 2,788, 2,339), 63.4% and 66.1%, IIA (n = 203, 819), 55.4% and 54.5%; IIB (n = 899, 648), 48.6% and 46.4%: IIIA (n = 940, 1,216), 43.3% and 42.8%; IIIB (n = 407, 90), 41.6% and 40.3% and IV (n = 131, 256), 29.1% and 31.4%, respectively. The 5-year survival rates by p-stage (UICC Ver. 6 and Ver. 7) were as follow: IA (n = 5,611, 4,978), 85.9% and 86.8%; IB (n = 2,398, 2,552), 69.3% and 73.9%; IIA (n = 336, 941), 60.9% and 61.6%; IIB (n = 977, 848), 51.1% and 49.8%; IIIA (n = 1354, 1804), 41.0% and 40.9%; IIIB (n = 799, 106), 36.7% and 27.8%, and IV (n = 188, 434), 27.8% and 27.9%, respectively. The 5-year survival rates by histological type were as follow: adenocarcinoma, 74.9% squamous cell carcinoma, 59.1%; large cell carcinoma, 53.3% small cell carcinoma, 52.6%; and adenosquamous cell carcinoma, 50.8%. Operative death occurred in 48 cases (0.4%) and hospital death in 46 (0.4%).
