NCT00310180 · STUDY IN CONTEXT

Hormone Therapy With or Without Combination Chemotherapy in Treating Women Who Have Undergone Surgery for Node-Negative Breast Cancer (The TAILORx Trial)

Draft scope assessment: narrower. Linked by condition-string match at the cancer-entity level. The study's eligibility - stage, biomarker, treatment line and prior therapy - has not been reconciled against this page's definition, so its population is narrower than this page in ways not yet recorded. The condition was transformed or resolved through the terminology hierarchy to reach this cancer type, so the link itself is a candidate a reviewer must confirm. 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 (DFS) is defined to be time from randomization to first event, where the first event is any of ipsilateral breast tumor recurrence, local recurrence, regional recurrence, distant recurrence, contralateral second primary invasive cancer, second primary non-breast invasive cancer (excluding non-melanoma skin cancers), or death without evidence of recurrence. The distribution of DFS (eg, 5-year DFS rate) is estimated using Kaplan-Meier method, and compared between the two randomized arms (arm B vs. arm C) using stratified log rank test and stratified Cox proportional hazard model.

All eligible patients who had on-study data and follow-up data were included in the analysis

→

secondary · POSTED

Distant recurrence-free interval (DRFI) is defined as time from date of randomization or registration to the date of distant recurrence of breast cancer, or of death with distant recurrence, if death is the first manifestation of distant recurrence. The distribution of DRFI (eg, 5-year DRFI rate) is estimated using Kaplan-Meier method.

secondary · POSTED

Recurrence-free interval (RFS) is defined as time from date of randomization or registration to the date of first recurrence of breast cancer (ipsilateral breast tumor recurrence, local/regional recurrence, distant recurrence) or to the date of death with recurrence, if death is the first manifestation of recurrence. The distribution of RFS (eg, 5-year RFS rate) is estimated using Kaplan-Meier method.

secondary · POSTED

Overall survival (OS) is defined as time from date of randomization or registration to date of death from any cause. The distribution of OS (eg, 5-year OS rate) is estimated using Kaplan-Meier method.

secondary · POSTED

Disease-free survival (DFS) is defined to be time from randomization to first event, where the first event is any of ipsilateral breast tumor recurrence, local recurrence, regional recurrence, distant recurrence, contralateral second primary invasive cancer, second primary non-breast invasive cancer (excluding non-melanoma skin cancers), or death without evidence of recurrence. DFS is evaluated by recurrence score (0-10 vs. 11-15 vs. 16-20 vs. 21-25 vs. \>25) and age groups (\<=50 vs. 51-65 vs. 65-75). The distribution of DFS (eg, 5-year DFS rate) is estimated using Kaplan-Meier method.
