超声内镜对胃肌原性肿瘤良恶性的量化鉴别

目的 :对胃肌原性肿瘤 ( gastruc myogenic tumor,GMT) ,以量化积分法鉴别其良、恶性。方法 :应用超声内镜 ( endoscopic ultrasonography,EUS)对 48例胃肌原性肿瘤患者作检查 ,根据肿瘤的大小、边缘、内部回声及有无液化计算积分 ,判断其良、恶性 ,最后与病理对照 ,验证其准确性。结果 :43例与病理结果相符( 89.6 %) ;5例不符 ( 10 .4%)。积分范围在 2 .0～ 3.0之间时 ,超声内镜与病理结果相差最大。结论 :积分 <1.0的肿瘤可定期随访 ;积分 1.0～ 2 .0的肿瘤应密切随访 ;积分 2 .0～ 3.0的肿瘤可结合活检 ,明确诊断 ;对于积分>3.0的肿瘤应采取积极有效的治疗方法。

Quantitative Differentiation of Gastric Myogenic Tumor by Endoscopic Ultrasonography

Objective:Quantitative differentiation of the benign and malignant gastric myogenic tumors,such as leiomyoma and leiomyosarcoma.Methods:Endoscopic ultrasonography was performed on 48 cases with gastric myogenic tumor.According to the size,margins, internal echo pattern,liquefaction of tumor, the scores of tumor were counted to defferentiate benign or malignant tumor and compare to patholotgy.Results:Forty-three cases were accordant with phathology(89.6%);5 cases were out of accordance with phathology(10.4%).There was a great deal of differences between endoscopic ultrasonography and phathology when the score range was 2.0 to 3.0.Conclusions:The score of tumors less than 1.0 should be followed up.The score range 1.0 to 2.0 should be followed up at regular intervals.Biopsy should be taken when the score of tumor was 2.0 to 3.0.When the score of tumors more than 3.0,effective treatment must be accepted.
