Recent data suggests the presence of cytotoxic (TIA-1 and granzyme B+) and regulatory T-cells (FOXP3+) in classical Hodgkin lymphoma (cHL) tissues has been shown to correlate with poor overall survival in mainly diagnostic biopsies. By tissue microarray analyses, we extend this observation to a cohort of relapsed/refractory cHL tissue biopsies and analyze immunohistochemical expression of FOXP3, TIA-1, and granzyme B in the inflammatory background and the tumor microenvironment. High expression of TIA-1 (>50%) correlated with poor overall survival (P<0.0001), low expression of FOXP3 (<25%) correlated with poor overall survival (P<0.01), and combined high TIA-1 (>50%) and low FOXP3 (<25%) correlated with poor overall survival (P<0.0001). Expression of cytotoxic and regulatory T-cells shows prognostic significance in the relapsed/refractory clinical setting of cHL.
近期数据表明,在经典型霍奇金淋巴瘤(cHL)组织中,细胞毒性T细胞(TIA-1和颗粒酶B阳性)和调节性T细胞(FOXP3阳性)的存在已被证明与主要诊断活检中的总体生存率较差相关。通过组织微阵列分析,我们将这一观察结果扩展至一组复发/难治性cHL组织活检,并分析了炎症背景和肿瘤微环境中FOXP3、TIA-1和颗粒酶B的免疫组化表达。TIA-1高表达(>50%)与总体生存率较差相关(P<0.0001),FOXP3低表达(<25%)与总体生存率较差相关(P<0.01),而TIA-1高表达(>50%)和FOXP3低表达(<25%)共同出现则与总体生存率较差相关(P<0.0001)。细胞毒性T细胞和调节性T细胞的表达在cHL的复发/难治性临床环境中具有预后意义。
