Abstract:
For locally advanced squamous cell carcinoma of the anal canal, efforts to discover effective treatments that would protect sphincter preservation led to the development of combined chemoradiotherapy, which, when administered appropriately, is curative. While the standard of combined modality chemoradiotherapy has minimally changed over the past 30 years, various chemotherapeutic and biologic agents, as well as novel methods for delivering radiation, have enhanced the treatment of anal carcinoma and are continuously being explored. This review examines the risk factors associated with anal carcinoma, and subsequently discusses the current standard of care from diagnosis through surveillance, paying attention to the pivotal trials that have shaped modern treatment paradigms.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
