Primary lung cancer is the leading cause of cancer-related deaths globally, and approximately 50% had metastatic disease at the time of diagnosis. A rectal mass and unintended weight loss are common manifestations of rectal cancer. Our case presented with a rectal mass, but workup revealed a metastatic lesion from lung cancer. Lung cancer metastases to the lower gastrointestinal tract imply reduced survival compared with the already poor mean survival of stage IV lung cancer. Despite relevant therapy, the patient died 5 months after referral.
原发性肺癌是全球癌症相关死亡的主要原因，约50%的患者在诊断时已发生转移性疾病。直肠肿块和意外体重减轻是直肠癌的常见表现。我们的病例表现为直肠肿块，但检查发现是肺癌转移灶。肺癌转移至下消化道意味着与IV期肺癌本就不佳的平均生存期相比，患者生存期会缩短。尽管进行了相关治疗，患者在转诊后5个月死亡。
