Prognostic role of ultrasonography staging in patients with anal cancer.

Background: Carcinomas of the anal canal are staged according to the size and extent of the disease; however, we propose including a novel ultrasound (US) staging system, based on depth of tumor invasion. In this study the clinical American Joint Committee on Cancer (AJCC) staging guidelines and the US classificationss in patients with anal cancer were compared.

Aim: To evaluate the prognostic role of the US staging system in patients with anal cancer.
