The relationships between the expression of ID2, EBV-LMP1 and P16(INK4A) in Chinese classical Hodgkin lymphoma are unknown and need exploring.
Samples of classical Hodgkin lymphoma from 60 Chinese patients were analyzed for the expression of ID2, EBV-LMP1 and p16(INK4A) proteins by immunohistochemistry.
ID2 protein was expressed in 83.3% of this group of classical Hodgkin lymphoma, staining strongly in both cytoplasm and nucleus of the Hodgkin and Reed-Sternberg (HRS) cells. EBV-LMP1 and P16(INK4A) were overexpressed in 85.0% and 71.7% of Hodgkin lymphoma, respectively. EBV-LMP1 was noted in the cytoplasm, membrane and nucleus of HRS cells; P16(INK4A) was in the nucleus and cytoplasm. Microscopically, ID2, EBV-LMP1 and P16(INK4A) staining distinguished the HRS cells from the complex background of lymphocytes. ID2 was positively correlated with EBV-LMP1(P < 0.01), but P16(INK4A) was inversely related to EBV-LMP1 (P < 0.05).
It is suggested that ID2, EBV-LMP1 and P16(INK4A) could play an important role in the evolution of classical Hodgkin lymphoma, and be considered as potential adjunct markers to identify HRS cells in diagnosis.
中国经典型霍奇金淋巴瘤中ID2、EBV-LMP1和P16(INK4A)的表达之间的关系尚不清楚,需要进行探索。
采用免疫组织化学方法分析60例中国经典型霍奇金淋巴瘤患者样本中ID2、EBV-LMP1和p16(INK4A)蛋白的表达情况。
该组经典型霍奇金淋巴瘤中83.3%表达ID2蛋白,在霍奇金和里德-斯腾伯格(HRS)细胞的细胞质和细胞核中均呈强染色。EBV-LMP1和P16(INK4A)在霍奇金淋巴瘤中的过表达率分别为85.0%和71.7%。EBV-LMP1在HRS细胞的细胞质、细胞膜和细胞核中均有表达;P16(INK4A)在细胞核和细胞质中表达。显微镜下,ID2、EBV-LMP1和P16(INK4A)染色可将HRS细胞与复杂的淋巴细胞背景区分开来。ID2与EBV-LMP1呈正相关(P < 0.01),而P16(INK4A)与EBV-LMP1呈负相关(P < 0.05)。
提示ID2、EBV-LMP1和P16(INK4A)可能在经典型霍奇金淋巴瘤的发生发展中起重要作用,可作为诊断中识别HRS细胞的潜在辅助标志物。
