【摘要】 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。更多还原

【Abstract】 One hundred and twenty cases of HCC (pathologically proven) verified by operation with measurement of liver scintisoan were collected during the period form January 1978 to August 1981. Of these 120 cases, real time B-scan ultrasonography had been carried out in 50 cases, and selective hepatoarteriography had been performed in 35 cases. The positive rates of angiography, B-scan and liver scan were 92.3%, 96.3% and 86.5% in HCC with diameter >5cm; 86.4%, 56.5% and 34.8% in HCC ≤5cm; 85.7%, 37.5% and 10.0% in HOC ≤3cm respectively. Moreover, only 93.0%, 66.7% and 60.0% of the actual size of tumor could be demonstrated respectively by using these methods. Data showed that the lowest limit of the size of HCC for differentiation was 1.2cm in angiography, 2cm in B-scan and 3cm in liver scan. Results indicated that meticulous B-scan detection by good hand was of proved merit to be a noninvasive initial screening and follow-up monitoring for early stage HCC. Angiography, however, might be used selectively in case when B-scan and liver scan had failed in the localization. While liver scan was promising only in large tumor.更多还原
