Intensity-Modulated Radiation Therapy for Anal Cancer: Toxicity versus Outcomes

August 15, 2010

The treatment of cancer of the anal canal has changed significantly over the past several decades. Although the abdominoperineal resection (APR) was the historical standard of care, a therapeutic paradigm shift occurred with the seminal work of Nigro, who reported that anal canal cancer could be treated with definitive chemoradiation, with APR reserved for salvage therapy only. This remains an attractive approach for patients and physicians alike and the standard of care in this disease. Now, nearly four decades later, a similar approach continues to be utilized, albeit with higher radiation doses; however, this strategy remains fraught with considerable treatment-related morbidities. With the advent of intensity-modulated radiation therapy (IMRT), many oncologists are beginning to utilize this technology in the treatment of anal cancer in order to decrease these toxicities while maintaining similar treatment efficacy. This article reviews the relevant literature leading up to the modern treatment of anal canal cancer, and discusses IMRT-related toxicity and disease-related outcomes in the context of outcomes of conventionally treated anal cancer.
