【 摘 要 】

Large cell neuoendocrine carcinoma forms an extremely aggressive and poor prognostic subset of neuroendocrine tumors with a tendency to early metastasis. However palliative chemotherapy in patients with metastatic disease may provide longer progression-free survival but the important issue is to detect and surgically treat the disease at an early stage. In this article, we  present a case of  large cell neuroendocrine carcinoma of the rectum which was admitted to our hospital with a complaint of rectal bleeding for about a month and multiple dsitant metastases at the time of diagnosis. The patient received palliative chemotherapy with cisplatin plus etoposide and zoledronic acid and an overall 6 month survival time was achieved. Generalizing the screening programs for colorectal cancers and facilitating access to colonoscopy are essential for early diagnosis and therapy of rectal neuroendocrine tumors.
