[Double primary cancer in the larynx and lung--report of 12 cases].
12 patients with double primary cancers in the larynx and lung were treated from 1958 to 1984. The incidence is 1.2% (12/943) of laryngeal carcinomas, 1.3% (12/904) of multiple primary cancers, 1.4% (12/873) of double primary cancers and 39% (12/31) of double primary cancers related to laryngeal cancers. There were 9 male and 3 female. 11 of the first primary cancers occurred in the larynx and only one in the lung. All were proved to be squamous cell carcinoma. In the 11 patients whose second primaries occurred in the lung, 4 were proved to be squamous cell carcinoma, one adenocarcinoma, one oat cell carcinoma, one poorly differentiated carcinoma and one cancer unclassified. Of 10 patients in whom both the first and the second primary cancer were treated, 6 survived for more than 2 years, 4 for 3 years and one for 5 years after the second treatment. It seems that double primary cancers of the larynx and lung could yield favorable results.
