Brian Butler %A Vivek Verma %A Waqar Haque %J SCIE-indexed Journal %D 2018 %X Combined chemoradiotherapy (CRT) for anal cancer (AC) is an efficacious measure which provides high rates of disease control and survival; it is thus the consensus paradigm to treat most cases of AC (1). However, concurrent CRT can also incur high rates of treatment-related toxicities, including perianal symptoms, which can be severely debilitating and substantially impair tolerance of full-dose CRT as well as quality of life. To this extent, radiation therapy (RT) has markedly advanced from the historical use of two- or three-dimensional conformal RT (2D/3DCRT) to inverse-planned intensity-modulated RT (IMRT), which creates highly conformal dose distributions and minimizes toxicities to several organs-at-risk (OARs) %U http://jgo.amegroups.com/article/view/20098/html
