Based on their findings, first study author Ciska Verbaanderd, from the University of Leuven in Belgium, and her colleagues say that the drugs “deserve further clinical investigations in several cancer types.”The review was recently published in the journal . While the United States has seen a fall in cancer death rates in recent years, the disease remains a significant burden on public health. Given that cancer is increasingly becoming resistant to existing therapies, there is a desperate need to uncover new ways to fight the disease. Plaquenil treat lupus Can you drink alcohol while on hydroxychloroquine Hydroxychloroquine is a substance that decreases immune responses in the body. Palbociclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Estrogen can cause the growth of breast cancer cells. Drugs, such as letrozole, may lessen the amount of estrogen made by the body. Hydroxychloroquine is a quinoline medicine used to treat or prevent malaria, a disease caused by parasites that enter the body through the bite of a mosquito. Malaria is common in areas such as Africa, South America, and Southern Asia. This medicine is not effective against all strains of malaria. This phase II trial studies how well hydroxychloroquine works in treating patients with previously treated prostate cancer. Autophagy destroys proteins and other substances in cells and may be used by prostate cancer cells to survive. Hydroxychloroquine, which blocks autophagy, may slow the growth of and possibly kill prostate cancer cells. CQ and HCQ are medications used to prevent and treat malaria. Last year, there were more than 1.6 million new cancer cases diagnosed in the U. Verbaanderd and colleagues believe that the drugs CQ and HCQ could help in this fight.

Maycotte P1, Aryal S, Cummings CT, Thorburn J, Morgan MJ, Thorburn A. Chloroquine CQ is a 4-aminoquinoline drug used for the treatment of diverse diseases. The Chloroquine Story in Cancer Continues In the Pipeline. Hydroxychloroquine in Treating Patients With Rising PSA.. Clinical Trials Using Hydroxychloroquine - National Cancer Institute. New studies have shown the crucial role of chloroquine in cancer treatment and is been extensively used as a monotherapy or adjunct therapy in various types of cancer. Since chloroquine is an 'old' drug, repurposing it to help breast cancer patients should also be very cost effective." Hydroxychloroquine inhibits autophagy, a prosurvival process that breast cancer cells induce and that antiestrogens can stimulate. Whether interfering with this process can enhance breast cancer therapy remains unknown. Chloroquine has been used for many years to treat patients with malaria, lupus, and rheumatoid arthritis, but more recently, hydroxychloroquine has been evaluated as a treatment for pancreatic cancer, with encouraging preliminary results.
