Abstract:
Objective To study the relationships between microscopic marginal extensions and tumor types ,and ultrasonic characteristics of malignant liver tumors . Methods Two‐dimensional ultrasonography , contrast‐enhanced ultrasonography and ultrasound‐guided biopsy of hepatic tumors and surrounding hepatic tissues were performed in 78 patients with malignant liver tumor . Pathological microscopic extensions were observed after hematoxylin‐eosin staining of biopsy specimens . Results T he microscopic marginal extension rates of hepatocellular carcinoma ( HCC) ,intrahepatic cholangiocarcinoma ( ICC) and metastatic liver cancer ( M LC) were 62 .5% ( 30/48 ) ,87 .5% ( 7/8 ) ,and 91 .0% ( 20/22 ) ,respectively . For tumors with well‐defined and poorly‐defined two‐dimensional ultrasound boundary ,microscopic marginal extension rates were 50% ( 14/28) ,and 86% ( 43/50) . T umor type and two‐dimensional ultrasound boundary were independent predictors for microscopic extension rate ( P < 0 .05 ) . T he median microscopic extension distances of HCC ,ICC and M LC were 1 .0 ( 0 ,3 .0 ) mm ,4 .0 ( 2 .3 ,4 .0 ) mm ,and 2 .0 ( 1 .8 ,4 .0 ) mm ,respectively . T he distance of microscopic extension increased with tumor size . T umor type and tumor size were independent predictors for the distance of microscopic extension ( P <0 .05) . Conclusions ICC ,MLC ,and tumors with larger diameter or poorly‐defined two‐dimensional ultrasound boundary have a larger distance of microscopic extension .
