All grade 3 - 4 adverse events (AE) with treatment attribution of possibly, probably or definite based on CTCAEv4 as reported on case report forms were counted. Incidence is the number of patients experiencing at least one treatment-related grade \>=3 AE of any type during the time of observation. For those who were premenopausal pre-chemotherapy, at each follow-up visit (every six months) in order to assess for duration of amenorrhea and also premature ovarian failure.
