本文报告1980～1990年在我科住院的12例多发性原发性肺癌,占同期住院肺癌病人总数1815例的0.7％。其中有8例系同期性患者,4例为后期性患者。9例为单侧性病变,3例为双侧病变。在8例同期性患者中,有4例在术前通过X线,后经纤支镜检得到确诊;在4例后期性患者中,2例术前得到确诊,第二个原发癌在第一次手术后通过X线片定期随访发现,另外2例经开胸后被确诊。

12 cases of multiple primary lung cancers admitted in our department from 1980 to 1990 were reported. The incidence of multiple primary lung cancers among 1815 cases of primary lung cancers in our department admitted in the same period was 0.7 percent.There were eight synchronous cases and four metachronous cases. Nine cases were unilateral. three cases were bilateral. Among the eight synchronous cases, four eases of multiple primary lung cancers were definitely diagnosed before surgery by chest X-ray films or fiberoptic bronchoscopy. Among the four metachronous cases: two cases were definitely diagnosed before surgery as the second primary lesion by chest X-ray films takenduring periodic follow-up after the initial resection, while other two cases were proven by thoracotomy. Histologically, adenocarcinoma was relatively scarce, but epidermoid carcinoma was predominant.
