肺癌与多原发癌

目的：探讨原发性肺癌合并多原发恶性肿瘤的发生率以及原发性肺癌与多原发癌之间的关系。方法：回顾性分析1964年至1992年间因原发性肺癌接受外科手术治疗的病例。结果：全组共1019例原发性肺癌，21例（2．1％），合并多原发性恶性肿瘤，其中71．4％，多发性肿瘤位于消化道，28．6％位于消化道以外的其它脏器。5例第一原发癌与第二原发癌为同时发生，16例异时发生。结论：原发性肺癌患者容易患者其它脏器恶性肿瘤，术后除监测肺癌复发外，应定期监测多原发癌。

Carcinoma of the lung and multiple primary malignant tumors

Objective To evaluate the incidence of multiple primary malignancies combined with lung and other organs and their relationship. Methods All patients who consecutively treated for lung cancer from December 1964 to December 1992, were retrospectively analyzed regarding the recurrence of a synchronous primary tumor elsewhere in the body. Results Of total 1?019 patients reviewed, 21 (2.1%) had associated carcinoma of other organs. In these 21 patients, the incidence of associated aerodigestive tract cancer was 71.4% (15/21) and that of other organs was 28.6% (6/21). Five patients had simultaneous cancer with the lung cancer and 16 had metachronous cancer. Conclusion Multiple primary tumors in patients with carcinoma of the lungs is not a rare phenomenon. Surveillance programs for detection of second primary tumors should focus on these patients.
