Summary
This phase II trial tests how well turkey tail mushroom (TTM) works in treating post-menopausal women with HER2-negative, estrogen receptor (ER)-positive breast cancer undergoing surgery. TTM is a common mushroom. In traditional Chinese medicine, it is used for enhancing function and removing toxins, as well as for cancer, hepatitis, and infections. There is previous evidence of significant tumor shrinkage occurring in the 2-month window between diagnosis and surgery in women who have taken TTM. Giving TTM may be effective in treating post-menopausal women with HER2-negative, ER-positive breast cancer undergoing surgery.
Detailed description
PRIMARY OBJECTIVE: I. To determine changes in proliferation (Ki-67) in ER+HER2- breast cancers that receive turkey tail administration. SECONDARY OBJECTIVES: I. To assess associated adverse effects of coriolus versicolor extract (TTM). II. To determine if quality of life (QOL), mood and energy levels change while taking TTM. OUTLINE: Patients receive TTM orally (PO) twice daily (BID) starting at the time of study registration and continuing up to the day prior to standard of care (SOC) surgery (up to 20-42 days) in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up 7-30 days after last dose.
