The four main histologic categories of malignant small intestine tumors are (1) adenocarcinoma, (2) sarcoma, (3) carcinoid, and (4) lymphoma. Signs and symptoms may be chronic or acute and include bleeding, obstruction, pain, and weight loss. When chronic, the symptoms are so vague that early diagnosis is difficult. Often the diagnosis is made only at the time of surgery. Treatment is segmental resection of intestine with adequate margin of the tumor and resection of the regional lymph nodes. Prognosis is evaluated by tumor extension through the bowel wall and lymph node metastasis. The 5-year survival rates are low except for carcinoid and lymphomatous lesions.
（1）腺癌；（2）肉瘤；（3）类癌；（4）淋巴瘤。体征和症状可能是慢性的或急性的，包括出血、梗阻、疼痛和体重减轻。当症状为慢性时，症状非常模糊，难以早期诊断。通常仅在手术时才做出诊断。治疗方法是对肠段进行肿瘤边缘足够的切除，并切除区域淋巴结。通过肿瘤穿透肠壁和淋巴结转移来评估预后。除类癌和淋巴瘤性病变外，5年生存率较低。
