作者对1961～1985年间832例头颈鳞癌死亡病例的尸检结果进行了回顾性分析,目的是探明头颈部癌病人多原发癌(MPC)的发病率和发生部位、死于MPC的百分率以及尸检时MPC的发生率。甲状腺、涎腺、唇、头颈皮肤等部位的原发癌不在本文统计之内,对MPC的部位的分析也仅限于头颈、肺、食管。本资料表明832例头颈癌中150例(18％)为MPC,其中男130例,女20例,男女之比6.5:1。头颈各部位癌的MPC的发生率为:口咽21.4％(55/257);下咽21.3％(23/108);口腔18.6％(49/264);喉14.4％(21/146);鼻窦4.2
The authors retrospectively analyzed the autopsy results of 832 cases of head and neck squamous cell carcinoma deaths from 1961 to 1985 in order to determine the prevalence and incidence of multiple primary cancers (MPC) in head and neck cancer patients and the percentage of patients who died of MPC. And the incidence of MPC at autopsy. The primary cancers of the thyroid gland, parotid glands, lips, head and neck skin are not included in this article, and the analysis of the sites of MPC is limited to head and neck, lung, and esophagus. This data shows that 832 cases of head and neck cancer in 150 cases (18%) for the MPC, including 130 males and 20 females, male to female ratio of 6.5:1. The incidence of MPC in head and neck cancers was 21.4% (55/257) in oropharynx; 21.3% (23/108) in hypopharynx; 18.6% (49/264) in oral cavity; 14.4% (21/146) in larynx; 4.2
