Penile squamous cell carcinoma (SCC) is an uncommon condition in Western countries. Inguinal lymph nodes dissection can be curative in 20%-60% of node positive patients. However, there is a high complication rates from the dissection, thus accurate diagnosis of inguinal lymph nodes metastasis is required. Current non invasive methods to detect lymph nodes metastasis are unreliable. Dynamic Sentinel Node Biopsy (DNSB), ultrasonography (US), and fine needle aspiration (FNA) cytology were proposed to in an attempt to detect sentinel lymph node (SLN). Despite the initial high rate of false negative results, recent DSNB showed improved survival compared to wait and see policy as well as reduced mortality compared to prophylactic inguinal lymphadenectomy. In addition, the US guided FNA shown 100% of specificity in detecting clinically occult lymph nodes metastasis. We proposed an algorithm for management of lymph nodes in penile cancer and suggest that FNA with US guidance should be performed in all high risk patients and that therapeutic dissection should be performed if findings are positive. |
