[Anal canal cancer : epidemiology, work-up, treatment and perspective].

Abstract

Although rare, around 2 % of digestive tumours, anal canal tumours remain a pathology that should not be neglected. These are frequently underdiagnosed due to the affected region and the symptoms that can be confused with more common and benign pathologies such as haemorrhoids or anal fissures. The treatment of these tumours is mainly based on radio-chemotherapy to avoid heavy surgical treatment which remains the salvage option. This article aims to review the epidemiology, diagnosis, management, monitoring and future developments for these cancers.
