Abstract

Objective: The management of lymph node metastases is crucial in penile cancer surgery. Sentinel lymph node biopsy (SLNB) is a minimally invasive procedure used to assess the presence of lymph node metastasis. The objective is to evaluate the efficiency of SLNB in the treatment of penile cancer.

Methods: This retrospective observational study included 31 patients diagnosed with penile cancer who underwent surgery and SLNB at the National Hospital of Dermatology between January 2018 and May 2021.

Results: The average age of patients was 58.4 ± 12.3 years old. The majority of patients had a history of phimosis (87.1%) and a treatment delay of over 1 year (67.7%). All 31 patients with penile cancer had squamous cell carcinoma (SCC) as the histological type, with the majority undergoing partial penectomy (87.1%). Out of 61 inguinal regions examined in 31 patients, lymph node metastasis was detected in one region (3.2%). The average follow-up time was 45.2 ± 12.1 months. One SLNB-negative patient was found to have inguinal lymph node metastasis after 12 months, resulting in a false-negative rate of 50%. The complication rate was 8.2%.

Conclusion: SLNB utilizing a radioisotope tracer can significantly reduce the incidence and severity of complications associated with inguinal lymph node dissection in patients with penile cancer.
