Overview

Retrospective cohort study examines postoperative complications in Danish penile cancer patients, indicating risks associated with surgical procedures.

Key Points

  • This study aims to explore the risk factors and extent of postoperative complications following inguinal lymph node surgery in penile cancer.
  • Retrospective cohort study of penile cancer patients in Denmark diagnosed from 2013–2025.
  • Extraction of surgical, pathological outcomes, and complications from medical records.
  • Univariable and multivariable logistic regression with multiple imputation to assess predictors of complications.
  • Among 745 patients, complications occurred in 9% of sentinel node biopsy (SNB) and 31% of inguinal lymph node dissection (ILND) procedures.
  • Lymphoedema occurred in 47% of ILND patients versus 9% of SNB patients.
  • Higher lymph node yield predicted overall complications, with ILND having five- to nine-fold higher odds for lymphoedema compared to SNB.
