Effectiveness and Safety of Extended Lymph Node Dissection during Radical Surgery in Patients with Bladder Cancer: A

Objective:
Bladder cancer (BC) is the most common malignant tumour of the urinary system, and radical cystectomy combined with pelvic lymph node dissection (LND) is the standard treatment for BC. We conducted this meta-analysis to explore the efficacy and safety of extended lymph node dissection in radical cystectomy for BC.
Methods:
PubMed, Embase, ProQuest PsycINFO, CINAHL, Web of Science and The Cochrane Library databases were searched for studies on extended lymph node dissection during radical BC surgery. The search time limit was from the establishment of the database to December 2023. Screening and quality assessment of literature were conducted. This meta-analysis was conducted to evaluate the influence of different lymph node dissection methods on recurrence-free survival (RFS), overall survival (OS), operation time, 90-day readmission rate and postoperative complication rate.
Results:
A total of 15 studies were included, including 4854 patients. All studies were of high quality. This meta-analysis showed no statistically significant difference in the operation time, postoperative complications and 90-day hospitalisation rate between the two groups of patients. The harvested volume of lymph nodes, RFS and OS rate were not statistically different.
Conclusions:
Among patients with BC undergoing radical cystectomy, extended lymph node dissection did not have a significant effect on operative time, 90-day readmission rates or postoperative complication rates. Thus, extended lymph node dissection is a safe treatment that does not increase the patient's surgical risk.
