摘　　要：目的探讨表观扩散系数(apparent diffusion coefficient,ADC)值与肝细胞癌(hepatocellular carcinoma,HCC)组织学分级的相关性以及不同直径肿瘤的ADC值与HCC的相关性。方法回顾性分析2017年—2020年180例病理证实为HCC的病例资料,按肿瘤直径大小分为<2 cm、≥2 cm且<3 cm、≥3 cm且<5 cm、≥5 cm 4组,标为Ⅰ、Ⅱ、Ⅲ、Ⅳ组。分析ADC值与HCC组织学分级的相关性,并分析在不同直径肿瘤ADC值与HCC的相关性。结果高、中和低分化HCC的ADC值分别为(1.159±0.302)×10^(-3)、(0.951±0.213)×10^(-3)和(0.811±0.239)×10^(-3)mm^(2)/s,逐级降低(P<0.05)。ADC值与总体HCC的组织学分级呈负相关(r=-0.474),与Ⅰ~Ⅲ组HCC的组织学分级均呈负相关(r值分别为-0.663、-0.527、-0.364),而与Ⅳ组HCC的组织学分级无相关性。结论ADC值可以作为非侵入性预测HCC组织学分级的指标,预测结果受肿瘤大小影响,更适用于小肝细胞癌。Objective To investigate the correlation between apparent diffusion coefficient(ADC)value and hepatocellular carcinoma(HCC)grade and the correlation between ADC value and HCC in different tumor diameters.Methods A retrospective analysis of 180 cases with pathologically confirmed HCC from 2017 to 2020 were divided into four groups according to size:<2 cm,≥2 cm and<3 cm,≥3 cm and<5 cm,≥5 cm,labeled as group Ⅰ,Ⅱ,Ⅲ,and Ⅳ,respectively.Analyze the correlation between ADC value and HCC histological grade,and analyze the difference between theADC value and HCC in different tumor diameters.Results The ADC values of well,moderatlye and poorly differentiated HCC were(1.159±0.302)×10^(-3),(0.951±0.213)×10^(-3)and(0.811±0.239)×10^(-3)mm^(2)/s respectively(P<0.05).The ADC value was negatively correlated with the histological grade of HCC in general(r=-0.474),and negatively correlated with the histological grade of HCC in groups Ⅰ-Ⅲ,respectively(r=-0.663,-0.527,-0.364).There was no significant correlation between HCC grade and histological grade in Group Ⅳ.Conclusions ADC value may be a useful tool for non-invasively predicting HCC histological grade.The predictive value is affected by tumor size.It may be more suitable for small HCC.
