title: [Study of small hepatocellular carcinomas].
abstract: In order to evaluate the factors affecting patient survival, 32 patients with a solitary hepatocellular carcinoma (HCC) smaller than 5 cm have been studied. Most patients were diagnosed as having a HCC during the periodic follow-up examinations for their underlying liver disease. For HCCs smaller than 2 cm, ultrasonography demonstrated the highest detection rate compared with CT and angiography. In patients with tumors larger than 2 cm, a portal vein thrombus and/or satellite tumors were frequently recognized, resulting in a lower patient survival rate when compared to those with a smaller HCC. Results have indicated that early detection of such tumors without a portal vein thrombus and/or a satellite tumor, and an adequate hepatic resection, such as segmentectomy or subsegmentectomy, are most important factors HCC patient survival.
