胸腔以外的同时或以后出现肺内孤立阴影者在临床上不少见。过去把这种肺内阴影视为转移,并认为其他部位将有更多转移,因而对肺内病变放弃积极治疗。本文介绍21年间(49～70年)结肠癌患者有肺内阴影者54例的情况。其中25例为肺转移癌,29例为肺原发癌。42%无症状,其肺内阴影皆为常规胸部X射线检查所发现。85%(46/54,肺转移及原发肺癌各23例)在结肠癌治疗后数月到17年出现肺内阴影。8例为同时出现肺内阴影(2例为肺转移,6例为原发性肺癌)。
It is clinically not uncommon for individuals with isolated orphaned lungs to appear at or near the chest. In the past, this intrapulmonary shadow was considered to be a metastasis, and it was thought that there would be more metastases in other parts, and thus abandoning aggressive treatment of lung lesions. This article describes the case of 54 patients with colorectal cancer with pulmonary shadow in 21 years (49 to 70 years). Of these, 25 were metastatic carcinomas of the lung and 29 were primary lung cancers. Forty-two percent of patients were asymptomatic and their lung shadows were found on conventional chest X-rays. Eighty-five percent (46/54, lung metastasis and 23 cases of primary lung cancer, respectively) developed intrapulmonary shadowing several months to 17 years after colon cancer treatment. Eight patients had simultaneous pulmonary shadowing (2 lung metastases and 6 primary lung cancers).
