虽然约50%的肺癌在最初诊断时有远处转移，但结肠转移极为罕见。本文报告一例罕见的原发性肺鳞状细胞癌发生结肠转移的病例。一位60岁女性因厌食症和疲劳被转介到我院肺外科。患者被诊断为原发性肺鳞状细胞癌，T2b N3 M1b IV期，并开始放化疗。这种治疗导致了良好的部分反应，原发肺病变没有任何新的转移性病变。患者6个月后因乙状结肠肿瘤出现左腹痛，术前诊断为原发性结肠癌。患者行结肠切除术，病理标本显示为低分化鳞状细胞癌，怀疑为原发肺癌结肠转移灶。术后过程很顺利，她出院了。肺癌的化疗安排在肺外科。本文报告一例罕见的肺癌结肠转移病例。当晚期原发性肺癌患者主诉出现腹部症状时，应考虑肺癌的胃肠道转移。
Although about 50% of lung cancers have distant metastasis at the time of initial diagnosis, colonic metastases are extremely rare. This report presents a rare clinical case of colonic metastasis from primary squamous cell carcinoma of the lung. A 60-year-old female with anorexia and fatigue was referred to the department of pulmonary surgery in our hospital. The patient was diagnosed with primary squamous cell carcinoma of the lung, T2b N3 M1b Stage IV, and chemoradiotherapy was initiated. This treatment led to a good partial response in the primary lung lesion without any new metastatic lesions. The patient developed left abdominal pain due to a bulky sigmoid colon tumor 6 months later, and was preoperatively diagnosed with primary colon cancer. She underwent colonic resection, and the pathology specimen demonstrated poorly differentiated squamous cell carcinoma that was suspected to be colonic metastasis from the primary lung cancer. The postoperative course was uneventful, and she was discharged. Chemotherapy for the lung cancer was scheduled in the department of pulmonary surgery. This report presented a rare case of colonic metastasis from lung cancer. When patients with advanced primary lung cancer complain of abdominal symptoms, we should consider gastrointestinal tract metastasis from lung cancer.
