OBJECTIVE: To detect the expression of galectin-3 (gal-3) and Sambucus nigra agglutinin (SNA) and determine their clinicopathological significance in breast cancers and benign breast lesions.
METHODS: Envison immunohistochemistry for staining gal-3 expression, and ABC affinity-cytochemistry to detect SNA expression were used in paraffin-embedded slides from specimens of breast cancers (n=60) and benign lesions (n=30).
RESULTS: The positive rates and scoring means of gal-3 and SNA were significantly higher in breast cancer (48.3%, 2.07 +/- 2.25, 2.12 +/- 2.26) than those in benign lesions (26.7%, 1.03 +/- 1.63, 1.07 +/- 1.59, P < 0.05). The scoring means of gal-3 and SNA expression were significantly lower in the positive cases of estrogen receptor (ER) and the negative ones of CA15-3 than those in the negative cases and the positive ones (P < 0.05).The survival analysis of Kaplan-Meier showed the 5-year survival rate and mean survival period were significantly lower in the gal-3 or SNA expression positive cases than those in the negative cases of breast cancer (P<0.01).
CONCLUSION: The expressive level of gal-3 and SNA lectins might have important effect on the carcinogenesis, progression and biologic behaviors of breast cancer. The positive cases of gal-3 and /or SNA expression might have poor prognosis.
