Summary

This trial is for women over 50 with hormone receptor positive, HER2 negative, node negative breast cancer. The study is testing whether reducing adjuvant endocrine therapy from 5 to 2 years is safe and does not reduce the expected excellent breast cancer specific outcomes for this population.

Who is the study for?

This trial is for women over 50 with a specific type of low risk, hormone receptor positive, HER2 negative breast cancer that hasn't spread. They must not have started endocrine therapy or had certain cancers in the last 5 years and should be expected to live at least another 5 years.

What is being tested?

The trial tests if taking Tamoxifen Citrate for just two years instead of five is safe and effective for older women with low risk breast cancer as determined by histopathologic criteria and Prosigna® score.

What are the potential side effects?

Tamoxifen Citrate can cause hot flashes, vaginal symptoms, leg cramps, blood clots, cataracts, changes in mood or libido among other side effects. The severity varies from person to person.

Trial Design

1Treatment groups

Experimental Treatment

Group I: standard of care endocrine therapy for two yearsExperimental Treatment1 Intervention

Standard of care adjuvant endocrine therapy for two years. for postmenopausal women, initial therapy will be aromatase inhibitor unless contraindicated, in which case tamoxifen may be used. For premenopausal and perimenopausal women, initial therapy will be tamoxifen unless contraindicated, in which case an lutenizing hormone releasing hormone (LHRH) agonist with / without aromatase inhibitor may be used.
