摘要: 目的 探讨在鼻咽癌组织中NFAT5和IGF1R的表达,分析其表达水平及其与临床特征和预后的相关性。 方法 收集2019年1月1日-2019年12月31日由云南省肿瘤医院收治的鼻咽癌组织及癌旁组织标本69例,采用免疫组织化学检测鼻咽癌组织中NFAT5、IGF1R的表达情况,Kaplan-Meier法预测生存时长,Log-Rank法对临床病理学特征展开预后评估。 结果 鼻咽癌组织中NFAT5和IGF1R的阳性表达比例分别为87%和84.5%,相较于癌旁的正常组织,它们在鼻咽癌中的表达显著增高(P<0.05),且二者的表达呈正相关(P<0.05),与T分期、N分期、颅底侵犯及颅神经麻痹相关(P<0.05);NFAT5、IGF1R过表达显著影响鼻咽癌患者的生存率,与预后呈负相关(P<0.05)。 结论 鼻咽癌组织中NFAT5和IGF1R两者过表达,表达水平呈正相关,与临床特征和预后显著相关,可成为判断鼻咽癌预后的肿瘤生物标志物。

Abstract: Objective To investigate the expression of NFAT5 and IGF1R in nasopharyngeal carcinoma tissues and analyze their expression levels in relation to clinical features and prognosis. Methods From January 1, 2019, to December 31, 2019, 69 cases of nasopharyngeal carcinoma tissues and adjacent non-cancerous tissues were collected from patients treated at Yunnan Cancer Hospital. Immunohistochemistry was employed to detect the expression of NFAT5 and IGF1R in nasopharyngeal carcinoma tissues. The Kaplan-Meier method was used to predict survival time, and the clinicopathological features were evaluated using the log-Rank test. Results The positive expression rates of NFAT5 and IGF1R in nasopharyngeal carcinoma tissues were 87.0% and 84.5%, respectively. Compared to adjacent normal tissues, the expression levels of NFAT5 and IGF1R in nasopharyngeal carcinoma tissues were significantly increased (P < 0.05). Furthermore, the expression of NFAT5 and IGF1R was positively correlated with T stage, N stage, skull base invasion, and cranial nerve palsy (P < 0.05). The overexpression of NFAT5 and IGF1R significantly affected the survival rate of patients with nasopharyngeal carcinoma and was negatively correlated with prognosis (P < 0.05). Conclusion In nasopharyngeal carcinoma tissues, overexpression of NFAT5 and IGF1R is observed, which is closely linked to clinical features and patient outcomes. These markers may serve as valuable indicators for predicting the prognosis of nasopharyngeal carcinoma. -
