胃良性和恶性病变组织中β-半乳糖凝集素3和接骨木凝集素的表达及其临床病理意义

Objective To study the expressive levels of galectin-3(gal-3) and sambucus nigra agglutinin (SNA) and their clinicopathological significance in the benign and malignant lesions of stomach. Methods EnVisonTM immunohistochemistry for assaying gal-3 expressive level and ABC cytochemistry for determining SNA expressive level were used in conventional paraffin-embedded sections from specimens of gastric cancer(n=49), peritumoral tissues(n=20), metastastic foci of lymph nodes(n=36), and different types of benign lesions(n=80). Results The positive rates of gal-3 and SNA were significantly higher in gastric cancer tissues than those in peritumoral tissues and different types of benign lesions (P<0.05, P<0.01). The positive cases of gal-3 and/or SNA in peritumoral tissues and benign lesions showed mild- to severe-atypical hyperplasia of mucous epithelial cells. No difference was found between the primary foci and metastatic foci in gal-3 and SNA expressions (P>0.05). The positive rates of gal-3 and SNA were significantly lower in histologic grade Ⅱ, infitrating depth T1,T2 and no-metastasis of regional lymph node than those in histologic grade Ⅲ, Ⅳ, infitrating depth T3,T4 and metastasis of lymph node in gastric cancer(P<0.05). The positive rates of gal-3 and SNA were higher in lymphnede metastatic site N1 and no-metastasis of distant organs than those in lymphnede metastatic site N2, N3 and metastasis of distant organs, but no significant difference was found (P>0.05). The consistence was found between the expression of gal-3 and SNA in gastric cancer tissues (χ2=6.59,P<0.05). Conclusions The expressive levels of gal-3 and SNA may be important molecular markers of lectins for reflecting the carcinogenesis, progression and biological behaviors in gastric cancer.
