摘要
目的探讨小肝癌(SHCC)螺旋CT血供分型与癌细胞分化程度、组织学类型的相关性。方法分析42例经手术病理证实的SHCC的螺旋CT征象及病理表现。将SHCC血供分为4型,分析SHCC血供类型与癌细胞分化程度和组织学类型的相关性。结果 42例SHCC中,肝动脉供血型共29例,占69%;肝动脉和门静脉双重供血型及少血供型,各5例,占11.9%;门静脉供血型3例,占7.2%。SHCC血供类型与癌细胞分化程度有显著性差异(P<0.05),分化程度较差组主要有肝动脉供血,而分化程度较好组除肝动脉供血外,门静脉亦参与供血。SHCC血供类型与病理组织学类型有显著性差异(P<0.05),大部分梁状型及实体型由肝动脉供血,纤维硬化型为乏血供。结论螺旋CT双期扫描能够反映SHCC血供分型,在一定程度上反映了癌细胞分化程度和组织学类型,有利于治疗方案的选择及预后评估。
Objective To study the correlation between supply types on spiral CT and the pathological changes in small hepatocellular carcinoma. Methods Dynamic spiral CT characteristics and pathological findings in 42 patients with pathologically-proved SHCC were analyzed and compared. The patterns of SHCC were divided into 4 types： arterial blood supply, portal blood supply, arterial combine with portal blood supply, and poorly blood supply. The correlated of CT features of tumor blood supplies with pathologic changes were analyzed. Results 29 （69%） cases were supplied by hepatic arterial blood, 5 （11.9%） by arterial combine with portal blood suppling and poorly blood suppling respectively, 3 （7.2%） portal blood suppling. The patterns of tumor blood supplies in SHCC correlated with tumor ceils differentiation （P〈 0.05 ） . SHCC with better tumor cells differentiation was more associated with poffal blood supplies. The patterns of tumor blood supplies in SHCC correlated with histological types of tumor cells （P 〈 0.05） . The entire compact and most of the trabecular SHCC were supplied by arterial blood, all of the scirrhous SHCC were lack of blood supplies. Conclusion The blood supply type of SHCC that reflects the cancer cell differentiation degree and the histological grades can be judged to some extent using spiral CT during dual-phase scanning.
