Beta-1,4-galactosyltransferase II is found to be associated with the alterations of tumor-related glycosylation. However, the clinical significance of beta-1,4-galactosyltransferase II in non-metastatic clear-cell renal cell carcinoma has not been reported up to now. Herein, our researches suggested that the expression level of beta-1,4-galactosyltransferase II was first found to be positively associated with tumor size, Fuhrman grade, lymphovascular invasion, rhabdoid differentiation, tumor necrosis and poor overall survival and recurrence-free survival of patients with non-metastatic clear-cell renal cell carcinoma, both in training set and validation set. Moreover, beta-1,4-galactosyltransferase II expression was identified as an independent adverse prognosticator for overall survival and recurrence-free survival of patients with non-metastatic clear-cell renal cell carcinoma. Ultimately, prognostic accuracy of the nomogram integrating beta-1,4-galactosyltransferase II with other independent prognostic parameters was dramatically improved for overall survival and recurrence-free survival of patients with non-metastatic clear-cell renal cell carcinoma. Taken together, beta-1,4-galactosyltransferase II is a potential independent adverse prognostic factor for postoperative recurrence and survival, which could be developed as a useful biomarker for non-metastatic clear-cell renal cell carcinoma by a series of further independent and retrospective studies, so as to help the postsurgical management of clear-cell renal cell carcinoma patients.
