AI Article Synopsis
- This study explores the use of 3D-printed brachytherapy applicators for precise skin cancer treatment, focusing on applicator placement accuracy and reducing air gaps.
- A cohort of 20 skin cancer patients received high dose rate (HDR) brachytherapy using custom-made applicators based on CT scans, showcasing a placement error of less than 1.0 mm on average.
- The findings confirm that personalized 3D-printed applicators enhance treatment precision, potentially improving patient outcomes by minimizing radiation exposure to healthy tissue.
Article Abstract
Background And Purpose: This study aimed to investigate the reproducibility of a novel approach using 3D printed brachytherapy applicators for the treatment of skin cancer. Specifically, we aimed to assess the accuracy of applicator placement and to minimize the existence of air gap pockets between the applicator and the patient's skin.
Materials And Methods: A total of 20 patients plans diagnosed with skin cancer were enrolled in this study. All patients underwent high dose rate (HDR) brachytherapy. To ensure precise applicator placement, patient-specific 3D printed applicators were designed based on individual body and tumor topography, utilizing data obtained from computer tomography (CT) scans. All applicators were fabricated using fused deposition modeling technology.
Results: The error in applicator placement was measured and found to be less than 1.0 mm on average, with a standard deviation of 0.9 mm. Additionally, the average error in air gap pockets between the applicator and the patient's skin was 0.4 mm (standard deviation was 0.5 mm). The study demonstrated that the personalized approach of 3D printed brachytherapy applicator placement in skin cancer treatment yielded highly accurate results. The average error of less than 1.0 mm in applicator positioning and the minimal air gap pockets demonstrated the reproducibility and precision of this technique.
Conclusion: Our study establishes the reproducibility and accuracy of 3D-printed brachytherapy applicator placement in the treatment of skin cancer. This personalized treatment approach offers a highly precise method for delivering radiation therapy, minimizing the risk to adjacent healthy tissues, and enhancing overall patient outcomes.

Background: Brachytherapy (BT) is routinely used in the treatment of various cancers. Current BT relies on the placement of large sources of radioactivity at the tumor site, requiring applicators that may cause local traumas and lesions. Further, they suffer from inflexibility in where they can be placed and some sources reside permanently in the body, causing potential long-term discomfort.

Background: Vaginal pessaries are a common method of managing pelvic organ prolapse (POP), as well as different types of urinary incontinence, allowing patients to successfully improve overall quality of life. Yet despite their positive attributes, there are several reasons why patients may choose to discontinue using pessaries and proceed with surgery to treat their condition instead. This study aimed to explore patients' experiences of pessary use in treating POP.

Purpose: Brachytherapy is associated with improved overall survival in cervical cancer patients, but the utilization seems hindered by high costs and relatively low reimbursement, particularly in the US. A one-room brachytherapy suite with CT (ORBT) could optimize the treatment workflow. By eliminating transport and waiting times, limiting applicator movement, and providing real-time applicator placement feedback, treatment time and costs could potentially be reduced.
