Clinicopathological study of primary malignant tumors of the lung: an analysis of 993 tumors resected at the Kanazawa University Hospital between 1979-1993.

摘要: A retrospective study was conducted of 993 malignant tumors the lung in 977 patients. The male-female sex ratio 2.6:1. age distribution males did not differ from that females and overall mean 64.3 +/- 9.5 years (range, 13-85 years). Forty-three percent patients were their seventh decade. location peripheral 81% central 19%. Of tumors, 85% squamous cell (epidermoid) carcinoma (SCC), while 58% adenocarcinoma (ADENO). In males, 49% all SCC 36% ADENO, 76% ADENO. incidence positive lymph node metastasis increased parallel with pT status both carcinomas. However, it noted that, carcinomas, no a diameter 15 mm or less had metastasis, whereas 18.9% ADENO this size for metastasis. These results indicate can occur even small-sized than mm. Thus, early detection surgery together mediastinal dissection are necessary to improve prognosis lung.
