Routine sentinel lymph node biopsy (SLNB) may help predict prognosis in patients with extramammary Paget disease (EMPD) of the genital area without clinical lymph node enlargement, according to study results published in the Journal of Dermatology.
Researchers sought to determine whether clinical characteristics and biomarkers before primary tumor resection could predict the invasion level of primary tumors and sentinel lymph node (SLN) metastasis in patients with EMPD. They retrospectively reviewed the data of patients who had primary tumor resection and SLNB for EMPD in the genital region from August 2002 to December 2024 at a single center.
