Anal cancer is an abnormal growth of cells in or around the anus or anal canal, the short passage through which bowel movements pass. The most common type of cancer found in this location is believed to be related to a type of viral infection linked to causing other types of cancers as well. Anal cancers are usually treated with radiation and chemotherapy, but surgery alone may be useful for very small or early anal cancers or when other therapy is not an option or unsuccessful in treating the anal cancer. Assessment for cancer spread and close follow up are necessary when treating anal cancer. This summary is intended for anyone wishing to learn more about anal cancer.
Age can affect the delicate physiologic balance of the internal anal sphincter diameters and pressure governed by Laplace's law. This study compares the effect of aging on the internal anal sphincter thickness and diameter in younger and older nulliparous females without symptoms of fecal incontinence undisturbed by an endoanal probe. All patients were scanned without endoanal coils to allow undistorted measurement of the internal anal sphincter diameters.
Treating anal high-grade dysplasia with infrared coagulation significantly increases the likelihood of complete clearance in individuals infected with HIV, according to a study recently published in Clinical Infectious Diseases. This randomized, open-label, multisite clinical trial included individuals living with HIV who were at least 27 years old. The participants were randomized to receive treatment via infrared coagulation or active monitoring.
