These tumours are highly aggressive as distant metastases occur even when the primary tumour is limited to the submucosa or mucosa. Despite the mean survival being around 6 months, long-term survival may be achieved in patients with localized disease treated with curative resection and adjuvant therapy. We report on a patient with Dukes' C small cell carcinoma (SCC) of the rectum who underwent surgery followed by pelvic irradiation and chemotherapy and achieved long-term survival.eninfo:eu-repo/semantics/closedAccessCombined Modality Therapy; Rectal Cancer; Small Cell Neuroendocrine CarcinomaChromogranin; Cisplatin; Cytokeratin; Etoposide; Neuron Specific Enolase; Synaptophysin; Adult; Article; Cancer Combination Chemotherapy; Cancer Incidence; Cancer Localization; Cancer Radiotherapy; Cancer Staging; Cancer Surgery; Cancer Survival; Case Report; Colon Carcinoma; Colorectal Cancer; Computer Assisted Tomography; Constipation; Female; Gastrointestinal Mucosa; Human; Immunohistochemistry; Irradiation; Long Term Care; Metastasis; Pain; Pelvis; Postoperative Care; Radiation Dose Fractionation; Rectum Carcinoma; Rectum Hemorrhage; Small Cell Carcinoma; Submucosa; Undifferentiated CarcinomaArticle7175772-s2.0-0036232978Q3
