Bladder cancer is the most common malignant tumor in the urinary system. The standard treatment of muscle-invasive bladder cancer (MIBC) is the radical cystectomy combined with pelvic lymphadenectomy. In recent years, radiotherapy has played an important role in the MIBC bladder-preserving treatment model. This article will review the advances in the application of radiotherapy for bladder preservation in MIBC, and introduce the application progress of radiotherapy in trimodality therapy of adjuvant radiotherapy and chemotherapy after transurethral resection of bladder tumors, radical radiotherapy, preoperative radiotherapy, radiotherapy combined with immunotherapy, the development and challenges of radiotherapy technology, and radiotherapy-related adverse reactions. The aim of this article is to provide a reference for further exploration of a more scientific and effective comprehensive treatment mode for bladder preservation.
Bladder cancer is one of the most common cancers of the urinary system. Baesd on the involvement of the blandder muscle or not, bladder cancer can be generally classified into muscule-invasive bladder cancer (MIBC) and non-MIBC. Cisplatin-based neoadjuvant chemotherapy followed by radical cystectomy is the standard treament recommended by current guidelines for MIBC. Based on the good efficacy of immunocheckpoint inhibitors in advanced bladder cancer. More and more studies have explored the safety and efficacy of immunotherapy in MIBC neoadjuvant therapy, and analyzed biomarkers to explore the benefit groups. This article reviews the latest progress of various neoadjuvant immunomonotherapy in MIBC, and prospect the future direction of development.
