Registered 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. The full summary is on the listing.

Registered summary

Despite enormous advances in thoracic surgery and oncology, two critical issues concern patients undergoing curative-intent surgery for lung, gastric and esophageal cancer: first, a majority (\~60%) of patients experience minor and major adverse events occurring during and in the days following surgery; second, patients worry about the significant risk of cancer recurrence and mortality months to years after surgery. These issues, combined with side effects of chemotherapy and radiation, have detrimental effects on health-related quality of life (HRQoL). The full summary is on the listing.
