[Studies on recurrent breast cancer--clinicopathological factors and p53, p21Cip1/Waf1 and cyclin D1 protein expression].
Of patients radically operated on for breast cancer in our department, 46 patients who had recurrent breast cancer were clinicopathologically evaluated to clarify the prognostic factors of recurrent breast cancer. Furthermore, p53, p21 and cyclin D1 protein expression were studied immunohistochemically and their prognostic value was evaluated. The relapse-free interval was highly related to the survival rate after the recurrence. p53 overexpression was correlated with the progression of clinical stage and lymph node metastasis and negatively correlated with the expression of estrogen receptor. The p21 positive and p53 negative cases had a significantly better prognosis than the p21 negative and p53 positive cases. The combination of p53 and p21 protein expression seemed to have prognostic value in recurrent breast cancer.
