Shown is a summary of clinical efficacy data from the randomised phase III trials of toremifene (40–60 mg/day) versus tamoxifen (20–40 mg/day) as first-line endocrine treatment of advanced breast cancer in postmenopausal women (oestrogen receptor status positive or unknown). aThe meta-analysis [32] was published in 1999 and included data from the first four trials [27-30], together with an unpublished small German study, but it did not include the Spanish study [31], which was published in 2001. ORR, objective response rate, including complete response and partial response; TTP, median time to disease progression.
