Split-course radiotherapy for urinary bladder cancer.

Area of Science:

• Oncology
• Radiotherapy
• Urogynecology

Background:

• Bladder cancer (carcinoma of the urinary bladder) is a significant health concern.
• Radiotherapy is a common treatment modality for bladder cancer.
• Optimizing radiotherapy schedules, such as split-course regimens, is crucial for patient outcomes.

Purpose of the Study:

• To evaluate the efficacy and outcomes of split-course radiotherapy in patients with T1-T4 bladder cancer.
• To compare survival rates based on tumor control achieved through different treatment combinations.
• To assess the feasibility and tolerability of the split-course regimen.

Main Methods:

• Retrospective analysis of 119 patients diagnosed with T1-T4 bladder cancer.
• Treatment involved a split-course radiotherapy regimen with a 3-week rest period.
• Radiation dose was increased by 10% to 6600 cGy to compensate for the break.
• Patient data on treatment completion, local tumor control, and survival were analyzed.

Main Results:

• 86% of patients completed the planned split-course radiotherapy.
• The actuarial 5-year survival rate for the entire cohort was 20%.
• Patients achieving local tumor control (via surgery and radiotherapy or radiotherapy alone) had significantly better 3- and 5-year survival rates compared to those with recurrent tumors.
• The split-course regimen yielded results comparable to continuous radiotherapy.

Conclusions:

• Split-course radiotherapy is a feasible treatment option for bladder cancer, with a high completion rate.
• Achieving local tumor control is a critical factor for improved survival in bladder cancer patients treated with radiotherapy.
• The split-course regimen demonstrates comparable efficacy to continuous radiotherapy for urinary bladder cancer.
