Clinically significant symptoms due to gastrointestinal metastases from primary lung cancers is rare. A case of life-threatening lower gastrointestinal haemorrhage secondary to metastatic squamous cell carcinoma of the lung is reported. Previous reports of such metastases are reviewed, with reference to management and prognosis. After resection of colonic metastases from squamous cell lung cancer, survival is similar to that for primary disease. It is suggested that patients with known or suspected squamous cell lung cancer presenting with lower gastrointestinal symptoms be managed as aggressively as those with no previous history of disease.
原发性肺癌发生胃肠道转移引起具有临床意义的症状较为罕见。本文报告一例因肺转移性鳞状细胞癌导致危及生命的下消化道出血病例。并参考治疗和预后情况，对既往此类转移的报告进行了综述。切除肺鳞状细胞癌的结肠转移灶后，生存率与原发性疾病相似。建议对出现下消化道症状的已知或疑似肺鳞状细胞癌患者，应像既往无疾病史的患者一样积极治疗。
