Purpose/Objective(s):
Brachytherapy is known to improve the overall survival rate in cervical cancer patients. However, its application is often hindered by long procedure times and complex workflows, particularly in the era of three-dimensional image-guided therapy. This study aims to assess the value of an optimized CT-guided brachytherapy workflow for cervical cancer.Materials/Methods:
We developed an optimized CT-guided brachytherapy workflow for cervical cancer and compared it with two conventional approaches: the multi-room brachytherapy workflow (MBRT) and one-room CT-guided brachytherapy (ORBT), taking into account staff utilization and equipment costs. We simulated both MBRT and ORBT scenarios and compared the treatment data, focusing on process time for each approach. Meanwhile, we verified errors before and after treatment with the applicator.Results:
Compared with MBRT, the optimized workflow reduced the overall treatment duration by an average of 28.4% (2412 ± 74s vs 3367 ± 78s), and the average time per patient was reduced by 70.4% (901 ± 21s vs 3427 ± 78s). Compared with ORBT, the average treatment time for doctors was reduced by 63.6% (901 ± 21s vs 2472 ± 70s), while maintaining treatment precision.Conclusion:
The current optimized workflow allows multiple patients to undergo brachytherapy simultaneously, with different treatment stages interspersed, enhancing work efficiency per unit time and avoiding waiting time for sequential treatment. Not only can it reduce the overall time of brachytherapy for each patient, it also improves the treatment efficiency for medical staff.
