Purpose
This study evaluates the addition melatonin and metformin to toremifene in the treatment of
locally advanced breast cancer. Third of patients will receive toremifene, other third will
receive combination of melatonin and toremifene and other patients will receive combination
of metformin and toremifene.
Detailed Description
The management of locally advanced breast cancer is complicated issue. Neoadjuvant treatment
is often needed to downstage locally advanced ER positive BC tumors prior to surgery.
However, many patients do not achieved objective response on treatment. The ability of
melatonin and metformin to decrease side effects of chemotherapy had been investigated,
moreover, several studies confirm, that this drugs in combination with conventional anti -
estrogen treatment may increase objective response. But, this data is still controversial. We
hypothesizes that the combinations of melatonin and metformin with conventional anti -
estrogen such as toremifene could be more effective than toremifene alone in terms of
response rate.
