Galectin-3 was shown to be involved in various biological events, including cell growth, adhesion, differentiation, angiogenesis, apoptosis, tumorigenesis, and metastasis. The prognostic significance of galectin-3 expression has already been evaluated in several cancers. However, its prognostic role has not been investigated in nasopharyngeal carcinoma. The loss of cell cycle control is one of the critical steps in the development of nasopharyngeal carcinoma. Cyclin D1 is one of the key proteins involved in cell cycle control and is essential for G1/S phase transition. Overexpression of cyclin D1 has been observed in several human cancers. In the present study, the expression of galectin-3 and cyclin D1 was evaluated with immunohistochemical analysis in 45 patients diagnosed as undifferentiated nasopharyngeal carcinoma and expression of these proteins was correlated with clinicopathological parameters and prognosis. Multivariate analysis showed that older age (>50 vs. ≤50) (
P
 = 0.028), distant metastasis at presentation (M
1
vs. M
0
) (
P
 = 0.001), and increased galectin-3 expression (>5% vs. ≤5%) (
P
 = 0.025) were independently correlated with poor overall survival. We found no statistically significant correlation between cyclin D1 immunoexpression and disease outcome. The Spearman’s correlation coefficient revealed a significant correlation between galectin-3 and cyclin D1 expression (
r
 = 0.425;
P
 = 0.004). Our findings suggested that the immunohistochemical analysis of galectin-3 might be useful in predicting prognosis in nasopharyngeal carcinoma.
