摘　　要：目的:探讨肺癌组织中半乳糖凝集素1(Gal-1)表达水平,分析其与临床病理特征的关系及对预后的评估价值。方法:选取我院2018年1月至2020年1月收治的130例肺癌患者,采用免疫组化法检测癌组织、癌旁组织中Gal-1表达情况。收集患者的临床病理资料,分析Gal-1表达与病理特征的关系。利用Cox多元回归模型分析肺癌预后的危险因素。以术后第1天为起始日、术后随访满12个月为截止时间,记录患者的总生存率。结果:肺癌组织中Gal-1阳性表达率为48.46%,高于癌旁组织的15.38%,且Gal-1阳性组临床分期Ⅲ期、淋巴结转移、脉管侵犯占比分别为50.79%、57.14%、38.10%,高于Gal-1阴性组的22.39%、19.40%、16.42%(P<0.05)。Cox多因素分析提示年龄≥60岁、临床分期Ⅲ期、淋巴结转移、胸膜浸润、脉管侵犯、Gal-1阳性表达是影响患者总生存期、无瘤生存期的危险因素(P<0.05)。Gal-1阳性组术后12个月的总生存率、无瘤生存率分别为66.67%、63.49%,低于Gal-1阴性组的88.06%、83.58%(P<0.05)。结论:肺癌患者癌组织中Gal-1阳性表达率较高,其表达可能与临床分期、淋巴结转移、脉管侵犯有关,有望成为评估预后的重要指标。Objective:To explore the expression level of galectin-1(Gal-1)in lung cancer tissues,analyze its relationship with clinical characteristics and its prognostic value.Methods:A total of 130 lung cancer patients admitted to our hospital from January 2018 to January 2020 were selected for research.Immunohistochemistry was used to detect the expression of Gal-1 in cancer tissues and adjacent tissues.The clinicopathological data of patients were collected to analyze the relationship between Gal-1 expression and pathological features.Cox multiple regression model was used to analyze the factors affecting the prognosis of lung cancer patients.From the 1st day after the operation as the starting day to the 12-month follow-up as the cut-off time,the overall survival rate of the patients was recorded.Results:The positive expression rate of Gal-1 in lung cancer tissues was 48.46%,which was higher than 15.38%in the adjacent tissues.In the Gal-1 positive group,the proportions of clinical stageⅢ,lymph node metastasis,and vascular invasion were 50.79%,57.14%,and 38.10,respectively,whitch were higher than 22.39%,19.40%,16.42%of Gal-1 negative group(P<0.05).COX multivariate analysis indicated that age≥60 years,clinical stageⅢ,lymph node metastasis,pleural invasion,vascular invasion,and positive expression of Gal-1 were risk factors affecting the overall survival and tumor-free survival of patients(P<0.05).The overall survival rate and tumor-free survival rate of the Gal-1 positive group were 66.67%and 63.49%,respectively,which were lower than 88.06%and 83.58%of the Gal-1 negative group(P<0.05).Conclusion:The positive expression rate of Gal-1 in cancer tissues of patients with lung cancer is relatively high,and its expression may be related to clinical staging,lymph node metastasis,and vascular invasion.It is expected to become an important indicator of prognosis.
