Docetaxel With a Phytochemical in Treating Patients With Hormone Independent Metastatic Prostate Cancer (PROTAXY)

April 9, 2013 updated by: Philippe Chollet, Centre Jean Perrin

Pilot Phase II Study of Docetaxel in Combination With a Dietary Phytonutrient in First Line Treatment of Hormone Independent Metastatic Prostate Cancer

RATIONALE : Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Dietary supplements, such as phytochemicals, may stop or delay the development of prostate cancer.
