objectives: To evaluate the expression of PBK/TOPK (PDZ-binding kinase/T-LAK cell-originated protein kinase) and its clinical significance in cervical cancer and cervical intraepithelial neoplasia.
PBK/TOPK expression was detected in 28 cases of low-grade cervical intraepithelial neoplasia (CINI), 62 cases of high-grade intraepithelial neoplasia and 80 cases of cervical cancer by immunohistochemistry (IHC). Then, the correlation between PBK/TOPK expression and clinicopathological features was quantitatively analyzed by measuring the positive unit (PU).
PBK/TOPK expression was significantly greater in cervical cancer than that in high-grade intraepithelial neoplasia and CINI (P < 0.05). Meanwhile, PBK/TOPK expression in high-grade intraepithelial neoplasia was significantly higher compared with that in CINI (P < 0.05). In addition, PBK/TOPK expression in cervical cancer significantly correlated with histological type, differentiation, lymph node metastasis, vaginal and cervical invasion, TNM stage and tumor size (P < 0.05).
PBK/TOPK expression is closely associated with cervical cancer and cervical intraepithelial neoplasia, which may be served as a useful target for tumor diagnosis and immunotherapy.
目的:评估PBK/TOPK(PDZ结合激酶/T-LAK细胞起源蛋白激酶)在宫颈癌和宫颈上皮内瘤变中的表达及其临床意义。
采用免疫组织化学(IHC)检测28例低级别宫颈上皮内瘤变(CINI)、62例高级别上皮内瘤变和80例宫颈癌中PBK/TOPK的表达。然后,通过测量阳性单位(PU)对PBK/TOPK表达与临床病理特征之间的相关性进行定量分析。
PBK/TOPK在宫颈癌中的表达明显高于高级别上皮内瘤变和CINI(P<0.05)。同时,高级别上皮内瘤变中PBK/TOPK的表达明显高于CINI(P<0.05)。此外,宫颈癌中PBK/TOPK的表达与组织学类型、分化程度、淋巴结转移、阴道和宫颈浸润、TNM分期及肿瘤大小显著相关(P<0.05)。
PBK/TOPK表达与宫颈癌和宫颈上皮内瘤变密切相关,可能作为肿瘤诊断和免疫治疗的有用靶点。
