研究概要

本分析表明,CD3 阳性 TIL(肿瘤浸润淋巴细胞)与 ADC mean 及 ADC max 呈负相关。扩散受限与 HCC 微血管密度增加相关。ADC 值有助于以非侵入性方式更好地表征 HCC 的肿瘤微环境。

研究思路结论见上方概要

影像学检查方式能够预测肿瘤的组织病理学特征,如细胞密度和增殖潜能,这在肝细胞癌(HCC)中也有所示。扩散加权成像可以反映肿瘤的细胞密度,并提供表观扩散系数(ADC)值作为定量成像标志物。本分析旨在阐明ADC值与HCC若干免疫组化特征之间可能存在的关联。

25例患者(4例女性;16%)符合本分析的纳入标准,平均年龄为63±8.9岁。主要纳入标准为术前9个月内可获得MRI检查以及可获得组织病理学分析。免疫组化特征包括programmed cell death-ligand 1(PD-L1)评分(免疫细胞评分[ICS]、肿瘤比例评分[TPS]和联合阳性评分[CPS])、glypican-3、TIL(肿瘤浸润淋巴细胞)、间质浸润淋巴细胞(SIL)、CD68阳性细胞和微血管密度(MVD)。ADC值测量为ADC max、ADC mean和ADC min。

CD3+ TIL与ADC max呈中度负相关(r = -0.50,p = 0.01),与ADC mean呈中度负相关(r = -0.52,p = 0.008)。CD34+ MVD在显示扩散受限的组中表达更高(均值40 10.8 vs. 54 5.5,p = 0.0046)。ADC值与CD68+阳性细胞、PDL-1、glypican-3表达或CD3+ SIL之间无相关性。

CD3+ TIL showed a moderate inverse correlation with ADC max ( r = -0.50, p = 0.01), ADC mean ( r = -0.52, p = 0.008). CD34+ MVD showed higher expression in the group that showed diffusion restriction (mean 40 10.8 vs. 54 5.5, p = 0.0046). There was no correlation between ADC values and CD68+ positive cells, PDL-1, glypican-3 expression, or CD3+ SIL.

The present analysis demonstrated an inverse correlation between CD3-positive tumor-infiltrating lymphocytes and ADC mean and ADC max . Diffusion restriction is correlated with increased microvessel density in HCC. ADC values could help to better characterize the tumor microenvironment of HCC in a non-invasive manner.
