Abstract:
Objective To investigate the expression of mutant BRCA2 gene in human breast cancer tissue and its clinic-healing significance.Methods The expression of mutant BRCA2 gene in breast cancer tissues and adjacent non-cancerous tissues of 66 patients' samples was detected using immunofluorostainning(IFS)and the correlation between the expression of mutant BRCA2 and patient's clinic-pathological characteristic was analyzed.Results Among 66 patients' samples,87.8%(58/66)were up-regulated expression of mutant BRCA2 protein in breast cancer tissues and 12.2%(8/66)was no significant difference of the mutant BRCA2 expression between the cancer tissue and its corresponding adjacent noncancerous tissues.The label index(LI)of mutant BRCA2 gene was higher in the cases of breast carcinoma's later clinical stage,poor tumor differentiation grade,breast scirrhus carcinomas,infiltrative breast carcinomas and metastasis.Conclusion The overexpression of mutant BRCA2 gene in human breast cancer tissue is positively related to the breast carcinoma's clinical stage,tumor differentiation grade,the tumor pathological type and metastasis,and it may influence the healing therapy of the breast cancer patients.
