Factor associated with postoperative complications of inguinal lymph node dissection for penile cancer Test

Abstract

Background: Inguinal lymph node dissection (ILND) is the standard of care for palpable, biopsy-proven lymph node metastases or high-risk groups for nonpalpable lymph nodes in the treatment of penile cancer. ILND is associated with a significant incidence of complications and adverse events, specifically wound complications. Few studies have identified risk factors related to postoperative ILND complications. Objective: The objective of this study was to assess the prevalence of 30-day postoperative complications and to identify risk factors associated with postoperative complications of ILND for penile cancer. Materials and Methods: This was a retrospective review of medical records for all patients who had ILND for penile cancer between January 2012 and December 2022. According to the modified Clavien–Dindo classification, the 30-day postoperative complications were collected. Using an ordinal univariate logistic regression model and multivariate analysis, potential risk variables for complications were determined. Results: A total of 60 patients were performed ILND. Sixty percent of the patients had a postoperative complication including wound infection 50%, wound dehiscence 36.7%, skin necrosis 26.6%, lymphocele 33.3%, leg edema 46.7%, and scrotal edema 16.7%. Higher grade of modified Clavien–Dindo classification was associated with body mass index (BMI) (odds ratio [OR] = 1.15; P = 0.03), diabetes mellitus (OR = 3.13; P = 0.04), American Society of Anesthesiologist classification ≥3 (OR = 1.14; P = 0.03), radical ILND (OR = 1.57; P = 0.01), and bilateral ILND (OR = 1.60; P = 0.02). In multivariate analysis, a higher grade of modified Clavien–Dindo classification was correlated with BMI (OR = 1.48; P = 0.01) and bilateral ILND (OR = 4.56; P = 0.01). Conclusion: ILND is associated with high rates of complication. The severity of the modified Clavien–Dindo classification was associated with BMI and bilateral ILND.
