Sentinel Lymph Node Procedure in Patients With Epidermoid Carcinoma of the Anal Canal

Abstract

The standardized technique was safe and highly effective in sampling inguinal sentinel lymph nodes in carcinoma of the anal canal. It also proved to be useful as an instrument to detect micrometastatic deposits in clinically normal nodes. Our early results suggest the sentinel lymph node procedure may have a role in guiding a more selective approach for patients with anal cancer. Additional studies in a larger patient population to determine the sensitivity and specificity of this method are warranted.
