Résumé
Large cell neuroendocrine carcinoma of the colon is rare, and its prognosis is very poor especially when diagnosed at a metastatic stage. Early diagnosis can allow early curative surgery that can increase the survival for more than 5 years. We report a 62-year-old man who presented for neurologic signs and symptoms followed by constipation. He was diagnosed with large cell neuroendocrine carcinoma of the colon with brain metastasis. Patient was treated with right hemi colectomy due to obstructive gastro-intestinal symptoms, followed by chemotherapy (cisplatin and etoposide). Because of its rarity, effective treatment of large cell neuroendocrine carcinoma of the colon has not been established. If local large cell neuroendocrine carcinoma is completely resected, the prognosis can be largely influenced, and patients can benefit from a 5-year survival rate of 61% compared to 0% in patients without curative surgery. However, most patients are metastatic and not candidates for curative resection. The efficacy of systemic chemotherapy is highest in patients with poorly differentiated neuroendocrine tumors with a combination of cisplatin and etoposide. Patient with metastatic large cell neuroendocrine tumor have very poor prognosis with a 1 year survival rate of 10% without curative surgery. Increasing awareness of these types of cancer and their prognosis, may allow better comprehension of the importance of screening to allow early diagnosis and better outcomes. In case of late presentation, palliative surgery is always a must in patients with obstruction, bleeding or perforation.

BACKGROUND
BACKGROUND
Large cell neuroendocrine carcinoma of the colon is rare, and its prognosis is very poor especially when diagnosed at a metastatic stage. Early diagnosis can allow early curative surgery that can increase the survival for more than 5 years.
CASE REPORT
METHODS
We report a 62-year-old man who presented for neurologic signs and symptoms followed by constipation. He was diagnosed with large cell neuroendocrine carcinoma of the colon with brain metastasis. Patient was treated with right hemi colectomy due to obstructive gastro-intestinal symptoms, followed by chemotherapy (cisplatin and etoposide).
DISCUSSION
CONCLUSIONS
Because of its rarity, effective treatment of large cell neuroendocrine carcinoma of the colon has not been established. If local large cell neuroendocrine carcinoma is completely resected, the prognosis can be largely influenced, and patients can benefit from a 5-year survival rate of 61% compared to 0% in patients without curative surgery. However, most patients are metastatic and not candidates for curative resection. The efficacy of systemic chemotherapy is highest in patients with poorly differentiated neuroendocrine tumors with a combination of cisplatin and etoposide.
CONCLUSION
CONCLUSIONS
Patient with metastatic large cell neuroendocrine tumor have very poor prognosis with a 1 year survival rate of 10% without curative surgery. Increasing awareness of these types of cancer and their prognosis, may allow better comprehension of the importance of screening to allow early diagnosis and better outcomes. In case of late presentation, palliative surgery is always a must in patients with obstruction, bleeding or perforation.
