目的 :对重复癌的发病情况进行回顾性调查。方法 :对 1 990～ 2 0 0 0年 1 0年间治疗的重复癌患者1 5例进行回顾性分析研究。结果 :1 5例中同时性重复癌 1例 ,异时性重复癌 1 4例。第 1原发癌为喉癌 ,第 2原发癌以肺癌最多。第 1原发癌为下咽癌 ,第 2原发癌多为上消化道癌。结论 :喉癌、下咽癌的重复癌发病率有增高趋势 ,其重复癌多发生于肺及上消化道 ,喉癌、下咽癌患者应重点检查肺部和上消化道 ,必要时行气管镜、食道镜、胃内窥镜检查以免漏诊。
Purpose : To retrospectively investigate the incidence of repeated cancers. Methods: A retrospective analysis was performed on 15 patients with repeated cancers treated from 1990 to 2000. RESULTS: In 1 of 5 cases, there were 1 case of simultaneous repetitive cancer and 1 case of heterotopic recurrent cancer. The first primary cancer was laryngeal cancer, and the second primary cancer was lung cancer. The first primary cancer was hypopharyngeal cancer, and the second primary cancer was mostly upper gastrointestinal cancer. Conclusion: The incidence of repetitive cancer in laryngeal cancer and hypopharyngeal cancer has an increasing trend. Repeated cancers mostly occur in the lungs and upper gastrointestinal tract. Patients with laryngeal and hypopharyngeal cancers should focus on the examination of the lungs and upper digestive tract. Mirror, esophagoscope, and gastroscopy to avoid missed diagnosis.
