hi, welcome to HCM i am Dr Das
first of all, to tell whether hormone therapy
will be effective or not, the condition.ER/.PR, HER2NEU status is needed. which you did not mentioned. if it was positive then prognosis is very good, but if not then prognosis is bad. more over you did not mentioned the histopathological report which is also important.
for metastasis, go for regular therapy.
