Radiation Oncology among Patients with Bladder Cancer

Abstract

Vasili Sentzoua

For some individuals with invasive bladder cancer, radical radiotherapy is a viable option to cystectomy, and postoperative radiotherapy may be justified in patients with a high risk of local recurrence. In this paper, we describe preoperative and postoperative radiation oncology consultations among bladder cancer patients in Ontario. Over the last few decades, the role of radiation (RT) in the treatment of urinary bladder cancer has changed significantly. Many protocols supporting the use of multi-modality therapy have recently been created, and the concept of organ preservation has begun to be revisited. Improvements in radiotherapy planning, verification, and delivery have provided a mechanism for optimising bladder cancer radiotherapy and overcoming challenges that have traditionally hampered the treatment's efficacy. They can improve the therapeutic ratio by minimising the amount of normal tissue irradiated, increasing the radiation dose, or using more extensive fractionation and synchronous chemotherapy regimens. These strategies show a lot of promise for improving bladder cancer treatment outcomes.
