肝胰肿瘤264例细针吸取细胞学诊断

目的 对比分析细针吸取细胞学和组织学检查对肝细胞癌及胰腺癌的诊断价值。方法 在B超引导下进行定位穿刺，应用细胞学和组织学方法观察了264例临床怀疑肝、胰占位性病变患者的针吸标本。结果 本组恶性肿瘤114例，良性病变150例。肝、胰恶性肿瘤细针吸取细胞学检查阳性率为89．5％(102／114)，其中肝恶性肿瘤诊断正确率为90．1％(82／91)；胰恶性肿瘤诊断正确率为86．7％(13／15)。结论 肝、胰恶性肿瘤的细胞学和组织学联合检查对提高诊断的阳性率及肿瘤准确分型有重要意义。

Cytological and histological diagnosis of hepatic and pancreatic tumor by fine needle aspiration biopsy

Objective To confirm the value of combined cytological and histological diagnoses of hepatocellular carcinoma and pancreatic carcinoma. Methods Total 264 cases of B-ultrasound guided fine needle aspiration biopsies were used in this study. Clinically, all the cases suspected as hepatic or pancrenatic tumors,were studied cytopathologically and histepathologically. Results 114 cases were diagnosed as malignant tumor, and 150 cases as benign tumor by histology. The positive rate of hepatic and malignant pancreatic tumor by FNA reached 89.5%(102/114), among which the correct rate of malignant hepatic tumor was 90.1%(82/91), and the correct rate of malignant pancreatic tumors was 86.7%(13/15). Conclusions Cytological diagnosis of hepatic and pancreatic carcinoma is one of very important methods with improved positive rate of the malignant tumor and is helpful for the differentiation between carcinoma, regeneration and metastatic malignacies.
