Recent advances in radiotherapy and its associated side effects in cancer—a review

摘要

Abstract BackgroundRadiotherapy (RT) is the chief nonsurgical method to control malignant tumors. RT has advanced in both methodological and biological aspects over the past few decades. Though RT is a momentous adjuvant non-invasive technique, it leaves behind some unsympathetic effects. Research is going on to surmount these pessimistic sides of RT.MethodsWe made a mini review of recent articles from the period of 2000 to 2017 regarding radiotherapy and its side effects in various types of cancers. The literature review was done by searching in PUBMED, MEDLINE, and SCOPUS.ResultsHere, we spotlight the physiological and genetic risks associated with the cancer patients undergoing RT. We illustrated the course of RT in most prevalent cancers tailored with dosage distribution. Radiation-induced mutation in the patients undergoing RT has been shown with evidence. Further, the major drawbacks like the development of radiation resistance in cancerous cells and secondary malignancies have been discussed. The problems associated with radiation dosage in terms of infertility and rejuvenation of reproductive cells has also been discussed. Finally, we discussed the latest treatment stratagem of RT in cancer.ConclusionCancer treatment will not be accomplished devoid of radiotherapy. But we can brace RT using radiosensitizers and ayurvedic radioprotectors.
