Registered outcomes7

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryRelapse Free Survival (RFS) 4 vs. 6 Cyclesfrom baseline up to 4 years
To determine if longer therapy, 12 weeks, is superior to shorter therapy, 8 weeks, of either CA or paclitaxel for relapse-free survival for women with primary breast cancer with 0-3 positive axillary lymph nodes. An assessment of the superiority of 6 cycles over 4 cycles will be conducted. This analysis combines Arm I and Arm III together, and Arm II and Arm IV together.
PrimaryDuration of Disease Free Survival (RFS)from baseline up to 6.4 years
To determine the equivalence of paclitaxel to CA as adjuvant therapy for women with 0-3 positive axillary lymph nodes, for disease-free survival. Objective progression is defined as the appearance of local (chest wall, axillary, supraclavicular nodes) or distant metastases. The trial is designed to show the equivalence of the experimental agent T with the standard agent combination CA, thus the 4 and 6 course arms of each drug will be combined to conduct this analysis.
SecondaryOverall Survival (OS)from baseline up to 5 years
To determine the equivalence of paclitaxel to CA as adjuvant therapy for women with 0-3 positive axillary lymph nodes, for overall survival. OS will be measured from study entry until death due to any cause. Survivors will be censored at the date of last follow-up.. The trial is designed to show the equivalence of the experimental agent T with the standard agent combination CA, thus the 4 and 6 course arms of each drug will be combined to conduct this analysis.
SecondaryAdverse Eventsfrom baseline up to 6 weeks post-treatment
To compare toxicities of short course CA and paclitaxel with long course CA and paclitaxel as adjuvant therapy for women with 0-3 positive axillary lymph node breast cancer. The percentage of patients that received a grade 3 or higher hematologic event will be reported here. We will be combining arm I with arm III, as well as arm II with arm IV. For a complete list of adverse events, please refer to the adverse events section.
SecondaryTime to Distant Metastasesfrom baseline up to 15 yearsLocal control and distant metastasis will be calculated as the cumulative incidence of first local relapse and first distant metastasis, respectively.
SecondaryLocal Controlfrom baseline up to 15 yearsLocal control will be calculated as the cumulative incidence of first local relapse.
SecondaryOverall Survival (OS) for 4 vs. 6 Cyclesfrom baseline up to 4 years
To determine if longer therapy, 12 weeks, is superior to shorter therapy, 8 weeks, of either CA or paclitaxel for overall survival for women with primary breast cancer with 0-3 positive axillary lymph nodes. An assessment of the superiority of 6 cycles over 4 cycles will be conducted. This analysis combines Arm I and Arm III together, and Arm II and Arm IV together.
