Summary
- Opened in June 1996
- Completed accrual in March 2005 with ~15,250 randomized
- Follow-up to continue until at least 2010 to gather information on recurrence, second primary cancers, hospitalization and cause of death
Objective
- To assess reliably the balance of risks of prolonging adjuvant tamoxifen by at least 5 years among women who have already had about 5 years of tamoxifen and for whom there is uncertainty about whether they should stop now, or continue for a few years longer. There were no restrictions in this trial on hormonal status, age or nodal status at the time of diagnosis with the primary eligibility criterion being substantial uncertainty about whether to stop or continue tamoxifen (see above).
Scheme
Update
- 15,252 patients entered to date (March 2005): recruitment closed. Primary endpoint – all-cause mortality supplemented by analyses of recurrence-free survival, second primary cancers and non-fatal events leading to hospitalization.
