目的：分析胃肠道间质瘤(gastrointestinal stromal tumors，GISTs)的临床病理特点，探讨GISTs的临床病理因素与危险度分级的相关性。方法：回顾性分析77例手术切除的原发性GISTs患者的临床病理资料，检测GISTs的临床病理因素与危险度分级的相关性。结果：肿瘤是否囊性变、有无坏死、是否合并其他肿瘤是对GISTs危险度分级有显著影响的变量(P<0.05)。结论：肿瘤是否囊性变及有无坏死可以作为判断GISTs危险度分级的重要参考指标。
Clinicopathological features of gastrointestinal stromal tumors and influence factors of risk stratification
Objective: To analyze the clinicopathological features of gastrointestinal stromal tumors (GISTs), and to explore the correlation between clinical pathologic factors and risk stratification of GISTs. Methods: The clinicopathological data of 77 cases of primary GISTs were analyzed retrospectively. The correlation between clinical pathologic factors and risk stratification of GISTs were detected by statistical method. Results: Whether the tumor is cystic degeneration, with or without necrosis, whether the merger of other tumors was GISTs risk stratification significantly affected variables (P<0.05). Conclusion: Whether cystic degeneration and necrosis can be used as an important reference index to judge the risk stratification of GISTs.
