Long-term Follow-up of Detaenial Sigmoid Neobladder Reconstruction for Paediatric Patients with Bladder and Prostate Rhabdomyosarcoma: Technique and Results from a Single High-volume Centre
European Urology(2022)
Abstract
Background: Rhabdomyosarcoma (RMS) is the most common paediatric soft-tissue sarcoma. Approximately 15-20% of RMS cases arise from the bladder and prostate (B/P). The optimal treatment strategy for B/P RMS remains unclear. Objective: To retrospectively evaluate the applicability of our procedure performed to treat paediatric patients with B/P RMS. Design, setting, and participants: This is a retrospective analysis from a single tertiary referral hospital. From August 2003 to March 2021, 62 children pathologically diagnosed with B/P RMS underwent radical cystectomy and orthotopic detaenial sigmoid neobladder reconstruction in our centre. Surgical procedure: Surgical procedures included laparoscopic radical cystectomy and detaenial sigmoid neobladder reconstruction, which is demonstrated in the accompanying video. Measurements: Demographic, clinical, and follow-up data were collected. Perioperative and long-term oncological and functional outcomes were reported. A logistic regression analysis was also performed. Results and limitations: All surgeries, including three intracorporeal laparoscopic surgeries, were completed successfully. Of the 62 patients, 54 were alive without evidence of disease recurrence or metastasis at the last follow-up. Five of the 14 >12-yr-old boys reported that they experienced erections. Two female patients >12 yr old reported that they menstruated. However, this was a retrospective study conducted at a single centre with limited surgeon experience. Conclusions: Our results confirmed the safety and feasibility of primary orthotopic sigmoid neobladder reconstruction after radical cystectomy for paediatric patients with B/P RMS. Good outcomes in terms of oncological control and functional recovery were achieved. The high histocompatibility and tissue adaptability of children are inspiring. Patient summary: We describe our stepwise technique of radical cystectomy and detaenial sigmoid neobladder reconstruction for paediatric patients with bladder and prostate rhabdomyosarcoma. With this technique, we were able to achieve good functional recovery without compromising cancer control and significantly increasing complications.
