PGR and breast carcinoma: As shown in Table 3, univariate analyses for breast cancer‐specific survival revealed Ki‐67, chemotherapy, histological grade, PR status, pT, adjuvant endocrine therapy, ER status, lymph node metastasis, and TACC2 status as significant prognostic variables in these cases, and subsequent multivariate analysis turned out that only PR status (P = 0.016) and TACC2 status (P = 0.040) were independent parameters of these cases in this study.
