Overall, TTF was 5.48 months. In patients without prior chemotherapy (n = 59), OS was significantly longer (p = 0.0131) than in patients with prior chemotherapy (n = 135). There was no strong correlation between TTF with fulvestrant and other endocrine therapies, total duration of endocrine therapy and maximum duration of endocrine therapy. TTF was significantly longer in patients with less than two prior chemotherapy regimens (p = 0.0093), \u003ci\u003ede novo\u003c/i\u003e metastatic disease (p = 0.0124) and without liver metastasis (p = 0.0024).
