Management of non ‐visualization following dynamic sentinel lymph node biopsy for squamous cell carcinoma of the penis

ConclusionPatients with impalpable inguinal lymph nodes undergoing DSNB with ≥G2 T1 disease should ideally have bilateral visualization of the sentinel lymph nodes, reflecting the drainage pattern from the primary tumour. In the present series, 12% of patients were found to have unilateral non‐visualization after DSNB. Among patients offered a repeat DSNB at a later date, localizing the sentinel node was successful in 86% of cases. Patients with favourable histological characteristics can be placed on clinical surveillance. Those with high‐risk disease can be offered a repeat DSNB procedure on the proviso that SML may be carried out if there is repeated non‐visualization. Larger cohorts are required to validate this proposed algorithm.
