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.
Oncology • Bladder Cancer • MIBC
To kill cancer cells, radiation therapy uses carefully targeted high-energy beams. It is possible to utilise a higher-than-usual dose of radiation since this treatment happens during surgery and can be supplied to a carefully specified location. While radiation is given, normal tissue, particularly the colon, can be temporarily relocated away from the treatment region or shielded with shielding devices. Many of the patients were confirmed by cancer researchers. The overall and cancer-specific survival rates were both high after a few years [1]. The majority of the survivors have a disease-free and functioning bladder. After surgery that does not remove the entire bladder, radiation therapy can be utilised as part of the treatment for some early-stage bladder malignancies. When surgery or chemotherapy is not an option for persons with early-stage malignancies, this is the treatment of choice [2]. Radiation therapy can help manage bladder cancer on its own. In this scenario, you may have a single session or up to some sessions spread out over four weeks, Monday through Friday. If you are too sick for previous therapies or if your cancer has spread to other parts of your body, this technique may be advised. Transurethral resection is frequently performed first to determine the extent of the cancer's spread into the bladder wall. The conventional treatment is chemotherapy followed by radical cystectomy (removal of the bladder and adjacent lymph nodes). Intra-operative radiation therapy is a treatment used during bladder cancer surgery to lower the chances of the tumour returning. This method uses small tubes called catheters that are implanted directly on the tissue to deliver strong radiation. This has the potential to kill cancer cells that linger after the tumour has been removed. Bladder cancer that has spread to the muscles is known as muscle invasive bladder cancer, MIBC occurs when the cancer has spread throughout the bladder wall (Stages T2 and beyond) [3]. The overall prognosis (how the disease will progress) for MIBC patients is determined by stage and treatment. Changes in bowel or bladder function may occur as a result of radiation to the bladder. Changes in the vaginal area erection issues (erectile dysfunction). Bladder cancer is normally treatable if diagnosed early, but it can be more difficult to cure if discovered later. Even with earlystage malignancies, recurrence is a possibility, thus constant monitoring is necessary after treatment or surgery. Bladder cancer does not normally produce significant pain when it is in its early stages. Some people have no pain when they urinate, whereas others suffer pain or burning when they do. The presence of blood in the urine, whether microscopic or apparent to the human eye, is a common symptom of bladder cancer. If bladder cancer is suspected, the following tests may be used to confirm the diagnosis: Examination of the body [4]. Blood tests are performed to determine the amount of chemicals produced into the bloodstream by organs and tissues in the body. The original tumour has commonly enlarged and pushed through the bladder wall by the time bladder cancer reaches stages. Cancer cells may have moved to nearby organs or further away organs such as the liver or lungs.
Recent advancements in radiation treatment planning, verification, and delivery procedures have made it possible to overcome hurdles that have previously hampered bladder RT. Current HT, VMAT, and ART approaches allow for a higher dose-escalation to the therapy targets with lower doses to the normal surrounding tissues and, as a result, reduced treatment-related toxicity. Because the volume of normal tissue irradiated is reduced, doctors will be able to improve the effectiveness of RT by increasing radiation dose, experimenting with extensive fractionation, and combining RT with systemic therapy.
