Abstract: This review study was aimed to overview the rectal cancer or colorectal cancer in meanwhile we intended to emphasize the staging methods of rectal carcinoma according to different evidence, also aimed to review the radiation therapy for rectal cancer, and comparing the evidence in that manner. We conducted a detailed search through medical electronic databases’ Medline/PubMed and Embase, searching studies discussing rectal cancer staging, radiotherapy, and risk factors associated with rectal cancer, published up to May, 2017. English language restriction was applied to the search and we included those studies with human subjects only. Rectal cancer staging defines neighborhood as well as distant extent of disease. Postsurgical pathologic hosting offers info on prognosis and also could show the demand for additional treatment. Pretreatment staging establishes management. Exact analysis of neighborhood T, N, as well as M classifications is most importantly crucial for identifying the best stage-specific therapy. Present assessment methods consist of physical examination, plain radiographs, EUS, MRI, accurate for staging. The trials have repetitively revealed that RT, whether alone or with radiation treatment, ought to be provided prior to surgical treatment to have the best effectiveness as well as the very least toxicity. It is also a belief that systemic therapy, being the weakest part of the treatment, need to be given before and not after the surgery in order to have biggest efficacy. Development of the local primary ought to after that not happen throughout the systemic therapy, presently needing a duration of 5-6 mo. The discovery that the short-course schedule results in significant down-staging, is bearable as well as permits complete radiation treatment beginning soon after the RT.
