胃原发恶性淋巴瘤在临床表现、内镜、X线检查及活检上很难与胃癌区别,术前诊断符合率仅占10%。其临床特点是:①发病年龄轻,较胃癌提前10年;②女性病人较胃癌多;③腹部包块及消化道出血较胃癌出现率高;④体征明显,自觉症状不重。X线特点:胃体、大弯侧病变居多,常出现胃内多发病变,但不引起;胃腔狭窄。内镜下具有多灶性、多形性、弥漫性改变,如糜烂、溃疡、结节、巨大皱襞混合存在。在病理上易与未分化癌相混淆。治疗上采取以手术为主的综合疗法。预后较胃癌好。
The primary gastric malignant lymphoma is difficult to distinguish from the gastric cancer in clinical manifestations, endoscopy, X-ray examination, and biopsy. The preoperative diagnosis coincidence rate is only 10%. Its clinical features are: 1 the age of onset is lighter than that of gastric cancer 10 years in advance; 2 female patients are more than gastric cancer; 3 abdominal mass and gastrointestinal bleeding have higher incidence than gastric cancer; 4 signs are obvious, and the symptoms are not heavy. X-ray features: The majority of gastric body, large curvature side lesions, often appear multiple lesions in the stomach, but does not cause; stomach cavity narrow. Endoscopic multifocal, polymorphous, diffuse changes, such as erosion, ulcers, nodules, huge folds exist. Pathologically confused with undifferentiated carcinoma. The treatment is based on a combination of surgery-based therapies. The prognosis is better than gastric cancer.
