Clinical Trial of Trametes Versicolor in Women With Breast Cancer

2014-08-26 22:30:31 | BioPortfolio


RATIONALE: Coriolus versicolor mushroom extract may slow the growth of cancer cells and may be an effective treatment for breast cancer.

PURPOSE: This phase I trial is studying the side effects and best dose of coriolus versicolor extract in treating women with stage I, stage II, or stage III breast cancer who have finished radiation therapy.




- To determine the maximum tolerated dose of oral coriolus versicolor extract in women with stage I-III, estrogen receptor- and/or progesterone receptor-negative or positive (as of 1/26/2009), infiltrating ductal adenocarcinoma of the breast who have recently completed standard post-surgery radiotherapy.


- To determine the feasibility of measuring changes in fatigue and quality of life of patients treated with this drug.

- To characterize the toxicity of this drug in these patients.

- To gather preliminary data that compare baseline and post-treatment immunologic measures, including differential blood counts (i.e., WBC), natural killer cell activity, phagocytic index, regulatory cell assay, T/B/NK cell population subset assays, peripheral blood mononuclear cell production of levels of interferon gamma, and tumor necrosis factor-alpha in these patients.

OUTLINE: Patients receive oral coriolus versicolor extract twice daily for 6 weeks.

Patients undergo quality of life and fatigue assessment at baseline, weekly during study, and at the 3-week follow-up visit.

Blood samples are collected periodically for immunological marker studies. Samples are analyzed for T-regulatory cell, T-and B-lymphocyte, and NK cell activity in peripheral blood mononuclear cells (PBMC), phagocytic index in monocytes and granulocytes, and cytokine secretion and upregulation by flow cytometry, cytotoxicity assays, cytolysis assays, T-regulatory cell assay, or T/B/NK cell population subset assays. Changes in the production of tumor necrosis factor-alpha and interferon-gamma in serum and in supernatants of PBMCs are analyzed via standard enzyme-linked immunosorbent assay.

After completion of study treatment, patients are followed at 3 weeks.

Medical and Biotech [MESH] Definitions

Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.

A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)

Carbohydrate antigen elevated in patients with tumors of the breast, ovary, lung, and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows particularly increased expression in the breast at lactation and in malignancy. It is thus an established serum marker for breast cancer.

Tumors or cancer of the human BREAST.

The phosphoprotein encoded by the BRCA1 gene (GENE, BRCA1). In normal cells the BRCA1 protein is localized in the nucleus, whereas in the majority of breast cancer cell lines and in malignant pleural effusions from breast cancer patients, it is localized mainly in the cytoplasm. (Science 1995;270(5237):713,789-91)
