通过手术验证120例病理证实的肝细胞癌(其中≤5厘米小肝癌共46例)几种定位诊断方法的价值,发现选择性肝动脉造影、实时B型超声显象和核素肝扫描在>5厘米肝癌的阳性率分别达92.3％、96.3％和86.5％,而≤5厘米小肝癌则分别为86.4％、56.5％和34.8％,对≤3厘米者差别更大,分别为85.7％、37.5％和10.0％;三者所显示肿瘤大小分别为手术所见实际大小的93.0％、66.7％和60.0％;三者能显示肿瘤的低限分别为1.2厘米、2厘米和3厘米。提示有经验的、细致的B型超声可作为非侵入性检测方法用于早期肝癌定位的初筛和复查,造影可在超声与扫描未能达到要求时选用,扫描仅对较大肝癌有价值。
The value of several localization diagnostic methods for 120 cases of pathologically confirmed hepatocellular carcinoma (≤5 cm small hepatocellular carcinoma in 46 cases) was verified by surgery, and selective hepatic arteriography, real-time B-mode ultrasonography, and radionuclide liver scan were found. The positive rate of 5 cm hepatocellular carcinoma was 92.3%, 96.3%, and 86.5%, respectively, while the small hepatic carcinomas ≤ 5 cm were 86.4%, 56.5%, and 34.8%, respectively, and the differences were greater for ≤ 3 cm, 85.7%, 37.5, respectively. % and 10.0%; the tumor sizes shown by the three were 93.0%, 66.7%, and 60.0% of the actual size seen by the surgery, respectively; the lower limits of the three tumors were 1.2 cm, 2 cm, and 3 cm, respectively. It is suggested that experienced and meticulous B-mode ultrasound can be used as a non-invasive detection method for the initial screening and review of early liver cancer localization. The contrast can be selected when ultrasound and scanning fail to meet the requirements. Scanning is only valuable for larger liver cancer.
