TRUS staging and follow-up in patients with anal canal cancer.

Purpose: The aim of our study was to define the role of grey-scale transrectal ultrasound in the evaluation, staging and follow-up of patients with histologically diagnosed anal canal cancer.

Materials And Methods: Seventy-six patients underwent digital rectal examination, anoscopy, abdomino-pelvic CT, inguinal and transrectal ultrasound; Fifty-five received combined chemoradiotherapy, whereas 21 received only radiotherapy due to clinical contraindications to chemotherapy. Before and after treatment TNM and UT staging were compared.
