CD44 is a cell-surface transmembrane glycoprotein that participates in the regulation of many cellular processes, including cell division, adhesion, migration and stem-like characteristics. CD63 is involved in the exocytosis process.
To evaluate the relationship between CD44 and CD63 expression and clinicopathological features, including tumor-infiltrating lymphocytes (TILs), phosphoinositide 3-kinase (PIK3CA) mutation and survival.
CD44 and CD63 were stained in samples from 101 breast cancer cases from Peruvian women.
Median age was 52 years, most were most were grade-3 (68%), estrogen receptor (ER)+ (64%) and stage II-III (92%). Median ki67 was 30%, median stromal TIL was 30% and mutation was found in 49%. Longer survival was associated with earlier stages ( = 0.016), lower ki67 ( = 0.023), ER+ ( = 0.034), luminal phenotype ( = 0.029) and recurrence ( < 0.001). CD44 was classified as high cell density staining in 57% and high intensity in 55%. High CD44 density was associated with younger age ( = 0.043), triple-negative phenotype ( = 0.035) and shorter survival ( = 0.005). High CD44 expression was associated with short survival ( = 0.005). High CD63 cell density was found in 56% of cases and was associated with ER-positive ( = 0.045), low TIL levels ( = 0.007), Luminal-A ( = 0.015) and low CD44 intensity ( = 0.032).
CD44 expression was associated with aggressive features and low CD63 density staining.
CD44是一种细胞表面跨膜糖蛋白,参与多种细胞过程的调节,包括细胞分裂、黏附、迁移和干细胞样特性。CD63参与胞吐过程。
评估CD44和CD63表达与临床病理特征之间的关系,包括肿瘤浸润淋巴细胞(TILs)、磷酸肌醇3激酶(PIK3CA)突变和生存率。
对101例秘鲁女性乳腺癌病例的样本进行CD44和CD63染色。
中位年龄为52岁,大多数为3级(68%)、雌激素受体(ER)阳性(64%)和II-III期(92%)。中位Ki67为30%,中位基质TIL为30%,49%发现有突变。生存期较长与早期阶段(P = 0.016)、较低的Ki67(P = 0.023)、ER阳性(P = 0.034)、管腔表型(P = 0.029)和无复发(P < 0.001)相关。57%的CD44被分类为高细胞密度染色,55%为高强度。高CD44密度与较年轻的年龄(P = 0.043)、三阴性表型(P = 0.035)和较短的生存期(P = 0.005)相关。高CD44表达与较短的生存期(P = 0.005)相关。56%的病例发现高CD63细胞密度,且与ER阳性(P = 0.045)、低TIL水平(P = 0.007)、管腔A型(P = 0.015)和低CD44强度(P = 0.032)相关。
CD44表达与侵袭性特征和低CD63密度染色相关。
