Anal canal cancer clinical practice guidelines in oncology
An estimated 3,990 new cases of anal cancer will occur in 2005, accounting for approximately 1.6% of digestive system cancers in the United States. Prognosis directly depends on the size of the primary tumor and the likelihood of lymphatic spread, with tumors 2 cm or smaller cured in 80% of cases. The NCCN guidelines recommend a thorough evaluation for any patient with a suspicious lesion in the anal canal and include additional recommendations for diagnosis, treatment, and follow up for anal canal cancer. © Journal of the National Comprehensive Cancer Network.
