RANGEL, Marcelo Fernandes et al. Malignant tumors of the small intestine. Rev. Col. Bras. Cir. [online]. 2000, vol.27, n.6, pp.385-388. ISSN 0100-6991.

Small bowel tumors are rare, and the majority of symptomatic lesions are malign. Benign tumors are a more frequent. Both benig and maligmant mors are associated with difficult diagnosis, because of atipic abdominal complaints, common to a large variety of digestives affections. Endoscopic and imaging examination may have diagnostic, but frequently are inconclusives. For primary tumors, the surgical resection is the treatment of choice, but for metastatic, tumors surgical resection has to be reserved for the cases complicated by obstruction, bleeding or perforation. This study has aim to analyse retrospectively 13 cases of small bowel maligns tumors in a period of 28 years. A higher incidence of primary tumors (69,2%), and linfomas (30,7%) were observed. Among metastatic tumors, the adenocarcinoma was the most frequent (15,4%). Segmental enterectomy was the most common surgical procedure (84,6%), and hospital mortality was 15,4%. Survival rate within five years was zero for metastatic tumors, while for primary lesions was 44,4%, suggesting a better prognostis for primary lesions, independently from the histologic type of neoplasms.
