Note: based on a RGCC chemosensitivity analysis I have seen at a German clinic, Hydroxychloroquine has been effective in killing the cancer cells of 5 out 7 patients that were tested. It is one of very few available drugs that inhibits autophagy, a mechanism associated with its anticancer properties. Aralen contraindicaciones Hydroxychloroquine 200 mg dosage Fundus autofluorescence in hydroxychloroquine toxicity Cancer is a disease in which cells in the body grow out of control. When cancer starts in the lungs, it is called lung cancer. Lung cancer begins in the lungs and may spread to lymph nodes or other organs in the body, such as the brain. Cancer from other organs also may spread to the lungs. Cures Within Reach funded lab research that suggested that chloroquine could improve the effectiveness of the cancer medication Tarceva erlotinib. The combination is now being studied in a phase II clinical trial at Massachusetts General Hospital in patients with stage IIIB and IV non–small cell lung cancer. Non-small cell lung cancer NSCLC is a type of malignant cancer, and 85% of metastatic NSCLC patients have a poor prognosis. C2-ceramide induces G2/M phase arrest and cytotoxicity in NSCLC cells. In this study, the autophagy-inducing effect of C2-ceramide was demonstrated, and cotreatment with the autophagy inhibitor chloroquine CQ was investigated in NSCLC H460 and H1299 cells. The results. In cancer, authophagy is the process used by cancer cells to “self-eat” in order to survive. Specifically, if authophagy is prolonged this will become a lethal process to cancer. duing chemotheraphy, radiotheraphy, etc.) authophagy is used by cancer cells to survive. However, note that Chloroquine has other properties as well that may be very well related to anti cancer mechanism, such as zinc ionophore, and others (see below the section on mechanisms).

A large body of evidence suggests that the relationship between autophagy and cancer is complex.42, 43 On the one hand, autophagy appears to inhibit malignant transformation, reflecting its capability to limit the accumulation of potentially oncogenic entities like depolarized mitochondria which overproduce potentially genotoxic reactive oxygen species, ROS. Chloroquine and hydroxychloroquine for cancer therapy. Cancers Free Full-Text Combination Therapy of Chloroquine.. Repurposing Drugs 101 - Chloroquine & Lung Cancer. Chloroquine as an Anti-autophagic Radiosensitizing Drug in Stage I-III Small Cell Lung Cancer Chloroquine The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Apr 14, 2014 Chloroquine diphosphate CQ, an anti-malarial drug, shows potential anti-cancer effects, such as the inhibition of cell growth in human lung cancer A549 cells, human breast cancer cells, and. Chloroquine's potential chemosensitizing and radiosensitizing activities in cancer may be related to its inhibition of autophagy, a cellular mechanism involving lysosomal degradation that minimizes the production of reactive oxygen species ROS related to tumor reoxygenation and tumor exposure to chemotherapeutic agents and radiation.
