Abstract
Urothelial carcinomas (UC) are the fourth most common tumours. Approximately, 50% of patients with invasive bladder cancer relapse after radical cistectomy (RC). In this report, we present the case of peritoneal carcinomatosis from bladder UC treated with cytoreductive surgery plus the administration of hyperthermic intraperitoneal chemotherapy (CRS + HIPEC). A 34-year-old woman diagnosed with high-grade bladder cancer with peritoneal recurrence in 2017. She underwent cytoreductive surgery followed by HIPEC with mitomycin C. Histopathological results showed metastases from UC in the left ovary and right diaphragmatic peritoneum. In 2021, the patient underwent surgery after treatment with atezolizumab for abdominal wall recurrence. Today, the patient is alive and free of tumor recurrence 12months after the last surgery. Despite advances in surgical technique and patient selection, the risk of relapse remains high among patients with muscle-invasive bladder cancer. We face the case of a young female patient with local, peritoneal, and lymphatic recurrence of bladder cancer after RC who had a partial response to chemotherapy. The possibility of CRS + HIPEC is offered by the surgical oncology unit, referent in the management of peritoneal carcinomatosis. Surgery is capable of resecting residual tumor in patients with a partial response or who have been erroneously underdiagnosed. CRS + HIPEC might be a valid option to be considered in well-selected patients and to be performed in reference units. There is a need for more collaborative clinical trials and prospective studies addressing the role of surgery in patients with metastatic bladder cancer.
