Primary tumors of the small intestine are rare, and metastatic ones are even rarer. It is exceptional for small bowel metastases to manifest before the primary tumor. The clinical presentation may require surgical resection motivated by intestinal perforation, hemorrhage or intestinal obstruction-subocclusion. Survival is scarce and generally does not exceed 20 weeks, regardless of the treatment performed.
小肠原发性肿瘤罕见，转移性肿瘤更是罕见。小肠转移瘤在原发性肿瘤之前出现实属例外。临床表现可能需要因肠穿孔、出血或肠梗阻 - 不全梗阻而进行手术切除。无论采取何种治疗，生存率都很低，一般不超过20周。
