Combination Chemotherapy With or Without Trastuzumab in Treating Women With Breast Cancer

Draft scope assessment: unclear. Attached because the study's own record names HER2. The study was not selected for this indication by its sponsor, and its eligibility has not been reconciled against this page in full. Found because this study's registry identifier is printed in an FDA approval notice, an FDA product label or an NCI summary held by this site. The citing document and the exact position of the identifier inside it are recorded. Being cited is not a statement that the study supports this treatment.

primary · POSTED

Disease Free Survival was defined as the interval from the date of randomization to the date of local, regional or metastatic relapse or the date of second primary cancer (with the exception of curatively treated non-melanoma skin cancer or in situ carcinoma of the cervix) or death from any cause whichever occured first. Disease free survival was estimated using the Kaplan-Meier method.
