目的观察胃间质瘤的临床及病理特点,分析其特征。方法回顾性研究我院确诊的78例胃间质瘤的患者,观察其临床及病理特征。结果本组患者中良性30例、交界性15例、恶性33例,不同性质肿瘤的直径差异有统计学意义,恶性肿瘤的生存期明显缩短。肿瘤的免疫表型以CD117和CD34表达为主要诊断依据。结论胃间质瘤临床常见,肿瘤直径、病理性核分裂像及免疫组化对判断间质瘤的性质及预后有重要价值。
Objective To observe the clinical and pathological features of gastric stromal tumors and analyze their characteristics. Methods A retrospective study of 78 patients with gastric stromal tumors in our hospital was performed to observe the clinical and pathological features. Results In this group of patients, 30 cases were benign, 15 cases were borderline and 33 cases were malignant. There was significant difference in the diameters of different kinds of tumors, and the survival time of malignant tumors was significantly shortened. The immunophenotype of the tumor is mainly based on the expression of CD117 and CD34. Conclusion The common clinical features of gastric stromal tumors, tumor diameter, pathological mitosis and immunohistochemistry to determine the nature and prognosis of stromal tumors of great value.
