Dynamic Sentinel Lymph Node Biopsy in Penile Carcinoma

Abstract

The term sentinel lymph node refers to the first lymph node or packet of lymph nodes to which tumor cells metastasize from a primary tumor. It is assumed that the process of micro-metastasis is embolic and that tumor cells are not present in continuity in the lymphatic channels between the primary site and sentinel lymph node. It is also therefore assumed that if the sentinel lymph node does not have tumor within it, the remaining nodes in the lymphatic basin are free of tumor.
