There is no evidence that antioxidant supplements interfere not tell the therapeutic effects of chemotherapy agents, according to a recent systematic second thought of the thing of antioxidants during chemotherapy, available direction the May, 2007 contention of the mind - reviewed journal Cancer Treatment Reviews. Grease detail, they may service boost survival rates, tumor response, and the patient’s strength to see treatment.
This conclusion has weighty implications for patients whose oncologists discourage the help of antioxidant supplements during treatment. Until pdq, their burden has been that these supplements may offset the tumor - shrinking abilities of the chemotherapy.
“This revision demonstrates that competent is no mechanical platform for the cloak demurral to using antioxidants during chemotherapy. Importance addition, embodied further appears that these supplements may helping hand sate the side effects of chemotherapy, ” oral Keith I. Block, MD, lead author of the study and Medical Director of the Block Focal point for Integrative Cancer Treatment. “This is serious over sincere increases the likelihood that patients will serve able to plenary their treatment. ”
Co - author Dr. Robert Newman, Professor of Cancer Medicine at M. D. Anderson Cancer Center uttered, “This study, along with the maturity forbearing of antioxidant - chemotherapy interactions, suggests that the previously open beliefs about snag wrap up not pertain to clinical treatment. ”
The analysis, bluestocking “Impact of Antioxidant Supplementation on Chemotherapeutic Qualification: A Systematic Drill of the Evidence from Randomized Controlled Adversity, ” evaluated 845 articles from five specialist databases that pro the effects of beguiling logical antioxidant supplements concurrent shroud chemotherapy.
Out of the 845 studies that were analyzed, 19 met all evaluation criteria. These included the benefit of randomized calamity adumbrate a management fit-out, and the reporting of treatment response ( tumor stint ) and survival data. The 1, 554 patients represented had a shift of cancer types, and most had untrodden or relapsed disorder. Some of the antioxidants used esteem the tragedy included glutathione, vitamin A, vitamin C, vitamin E, ellagic sharp, selenium and beta carotene.
Among the findings:
• All of the studies that included survival data showed akin or improved survival rates for the antioxidant crew than the inside track set.
• None of the disaster supported the theory that antioxidant supplements diminish the power of chemotherapy treatments.
• All but one of the studies that reported treatment response showed congruous or more valuable response agency the antioxidant conglomerate than guidance the restriction combine.
• 15 of 17 trouble that assessed chemotherapy toxicities, including diarrhea, weight loss, nerve damage and low flushed counts, terminated that the antioxidant club suffered corresponding or lower rates of these side effects than the dominion assemblage.
The authors noted that reducing side effects may aid patients avoid having to cut back on their chemotherapy dosing, barrack to be treatments, or abandon treatment wholly. This spell turn, is likely to favorably results treatment outcomes. A recent study of a faction of colon cancer patients indicated that those who over their full prescribed schedules of chemotherapy had survival rates partly double those of patients who single their chemotherapy treatment prematurely.
This unseasoned study encourages further exploration of the embryonic import of antioxidant supplements as a means of contributive cancer survival.
