摘要
目的探讨胃间质瘤超声内镜图像特征与术后病理危险度分级的相关性。方法对2017年5月至2022年6月65例在桂林市人民医院经超声内镜检查并行手术治疗,术后病理及免疫组化确诊为胃间质瘤患者的临床资料进行回顾性分析。依据肿瘤大小、核分裂象计数对患者进行危险度分级。比较不同危险度分级胃间质瘤患者的一般资料、超声内镜图像特征;分析超声内镜图像特征与不同危险度分级胃间质瘤患者的相关性。结果超声内镜图像显示,65例患者中以胃固有肌层起源最常见,病灶多呈低回声改变、回声均匀、边界规则,少部分存在溃疡及囊性变。根据术后病理危险度分级,其中极低危组36例(55.38%)、低危组19例(29.23%)、中危组7例(10.77%)及高危组3例(4.62%)。不同危险度分级胃间质瘤患者的性别、年龄、肿瘤部位、起源层次、回声强度无显著差异(P>0.05);肿瘤大小、边界、回声均匀性、溃疡、囊性变存在显著差异(P<0.05)。多因素Logistic回归分析结果显示,超声内镜下肿瘤大小、回声均匀性、囊性变与胃间质瘤危险度分级密切相关(P<0.05)。结论在不同危险度分级的胃间质瘤患者中,超声内镜图像特征具有一定的差异性,肿瘤大小、回声均匀性、是否存在囊性变是评估胃间质瘤危险度分级的重要指标。
Objective To investigate the correlation between endoscopic ultrasound image features and postoperative pathological risk classification of gastric stromal tumors.Methods The clinical data of 65 patients with gastric stromal tumors diagnosed by pathology and immunohistochemistry after endoscopic ultrasound and surgical treatment in Guilin People's Hospital from May 2017 to June 2022 were retrospectively analyzed.The patients were graded according to tumor size and mitotic count.The general data and endoscopic ultrasound image features of patients with gastric stromal tumors of different risk grades were compared.The correlation between endoscopic ultrasound image features and patients with different risk grades of gastric stromal tumors was analyzed.Results Endoscopic ultrasound image showed that the origin of gastric muscularis propria was the most common in 65 patients.Most of the lesions showed low echo changes,uniform echo,regular boundary,and a small number of ulcers and cystic change.According to the postoperative pathological risk classification,there were 36 cases(55.38%)in the very low risk group,19 cases(29.23%)in the low risk group,7 cases(10.77%)in the middle risk group and 3 cases(4.62%)in the high risk group.There were no significant differences in gender,age,tumor location,origin level and echo intensity among patients with different risk grades of gastric stromal tumors(P>0.05);there were significant differences in tumor size,boundary,echo uniformity,ulcer and cystic degeneration(P<0.05).Multivariate Logistic regression analysis results showed that the tumor size,echo uniformity and cystic change were closely related to the risk classification of gastric stromal tumors(P<0.05).Conclusion In patients with different risk classification of gastric stromal tumors,the endoscopic ultrasound images features have certain differences.Tumor size,echo uniformity,and the presence of cystic change are important indicators for evaluating the risk classification of gastric stromal tumors.
