Background: The management of penile cancer patients has some grey zones, one of them being the timing of prophylactic pelvic lymph node dissection. Here, we review the impact of timing of prophylactic inguinal and pelvic lymph node dissection on patients’ outcome. Methods: Relevant databases were searched according to recommendations by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Before the systematic review we present a narrative review on the indications for lymph node dissection and the impact of pathological anatomical considerations on the timing of prophylactic lymph node dissection and patients’ outcome. The primary research questions were disease-free and overall survival rate in patients who underwent early or late lymph node dissection after penile cancer diagnosis. Results: Four clinical trials were included in the systematic review. Conclusions: The survival rate of patients with penile cancer is strictly associated with the timing of prophylactic pelvic lymph node dissection. Even though there are no randomized controlled trials we conclude that there is evidence for a strong recommendation that lymph node dissection should be performed as soon as possible after diagnosis with3 months as a realistic cut-off time between early and late. According to the present evidence base, lymph node dissection should be offered the sooner the better to all patients at high risk of lymph node metastasis.
