Using a logistic regression analysis, HER2 positivity was significantly associated with higher CBR (HR = 0.38, p = 0.02); the presence of serous metastases was of borderline significance (HR = 0.55, p = 0.052), while a TN status and the presence of lung metastases were significantly associated with lower CBR rates (HR = 2.04, p = 0.044 and HR = 2.16 and p = 0.006, respectively).
