Expression and prognostic value of Galectin-1 protein in clear cell renal cell carcinoma
Objective:To examine alterations in the expression of Galectin-1 protein in clear cell renal cell car-cinoma(ccRCC)and assess its potential significance for predicting patient prognosis.Methods:The Galectin-1 protein expression was assessed using tissue microarrays and immunohistochemistry in surgically-resected tumor tissues and adjacent normal cells obtained from 173 patients with ccRCC.Follow-up data on the patients were gathered,and the analysis involved examining the correlation between Galectin-1 expression levels and clinicopath-ological parameters,as well as assessing its association with patient prognosis.Results:Immunohistochemical staining results showed that Galectin-1 protein was highly expressed in 28.9%(50/173)of ccRCC,while there was no expression in the adjacent normal tissues.There was a significant difference between the two groups(P<0.01).The statistical analysis results indicate that the protein expression level of Galectin-1 in ccRCC is signifi-cantly positively correlated with T stage,N stage,M stage,presence of necrotic areas,invasion of the renal pel-vis,sarcomatoid differentiation,and clinical stage(P<0.05).Simultaneously,the protein expression level of Ga-lectin-1 is closely associated with the prognosis of patients with ccRCC.Kaplan-Meier survival curves indicate that the survival time of patients with high expression is significantly shorter than that of patients with low expression(P<0.05).Further validation through multifactorial Cox regression analysis confirms that the high expression of Galectin-1 is identified as an independent predictor of adverse prognosis in patients with ccRCC.Conclusion:The expression of Galectin-1 protein elevated in ccRCC,suggesting its potential role as a molecular marker for anticipa-ting an unfavorable prognosis in patients with ccRCC.
