ABSTRACT

Introduction: The dynamic sentinel lymph node biopsy is an effective technique in the identification of nodal metastases in patients with diagnosis of penile cancer during the early stages of the disease.
Objective: To assess the validity of the radioguided sentinel node biopsy´s technique in penile cancer.
Methods: A retrospective, cross-sectional, descriptive and observational study was conducted between January 2017 and August 2019 at the National Institute of Oncology and Radiobiology of Havana, where there were studied six patients through a lymphatic mapping with sentinel node biopsy.
Results: In all the patients sentinel lymph nodes were located in the preoperative and transoperative lymphography with the gamma probe. The transoperative histopathological report of sentinel lymph nodes was the same as in the final report. Only one patient presented positive sentinel node of tumor cells, representing 17 % of the sample. In the follow-up period no patient had a relapse. It was obtained a 100 % of sensitivity, specificity, and positive and negative predictive value of the sample.
Conclusions: The lymphatic mapping with sentinel lymph node biopsy is a prognostic and staging tool which is useful for patients with penile cancer without palpable lymph nodes during the physical and radiological examination. It avoids subjecting them to a conventional lymph node dissection and its complications.
