Objective. The effectiveness of surgical resection of adenosquamous carcinoma of the lung remains poorly defined because of the histology' s relatively low frequency, the failure in most published series to separate adenosquamous carcinoma from the other variants of non-small cell lung carcinoma. To define the effectiveness of surgical treatment of adenosquamous carcinoma, we have retrospectively reviewed our hospital experience over a 12-year period. Methods. Retrospectively reviewed 22 cases of adenosquamous carcinoma who were surgically treated, except one patient,in the PUMCH from Jan. 1985 to Aug. 1997.This series constitutes the 1.9% of a total of 1 245 patients with all types of surgical treatment for the primary lung cancer during the same time. Results. The adenosquanous carcinoma was mostly presented in the old patients with a mean age of 60 years and mostly located in the peripheral of lung(n= 20).The overall 5-year survival was 23%.Those with stage Ⅰ tumors survival was only 18%(n= 13), stage Ⅱ 5%. The survival in stage Ⅲ tumors was not longer than 25 months and in stage Ⅳ survival was not longer than 12 months.Conclusion. Our results suggest that adenosquamous carcinoma of lung was a virulent tumor, which exhibited highly aggressive biological behavior with early lymph nodes metastasis(46% ) and its prognosis was worse than that of both squamous cell carcinoma and adenocarcinoma.
