Quantitative dosimetric analysis with independent software solutions and comprehensive treatment plan parameter evaluation in skin brachytherapy

: This study aimed to investigate quantitative dosimetric analysis with independent software solutions and comprehensive treatment plan parameter evaluation for the treatment of skin cancer. Specifically, we aimed to conduct a dosimetric analysis of the treatment plan and we presented the clinical parameters used in our institution of clinically used treatment plans. : This study compares dose calculations between BrachyVision v16.1 and RadCalc v7.2 for brachytherapy applications. It evaluates key treatment plan parameters, including V , V , V , D , CI, DNR, mean treatment depth, treatment time, and various Gamma values. Dose calculations utilized the 192-Ir GammaMed HDR Plus source. RadCalc employed a referenced model. Applicators were 3D printed using PLA as the printing filament. : The study assessed compliance for 20 patient plans, finding a mean dose difference of 0.05% with a standard deviation of 0.26%. V , V , and V showed high compliance, with V having a minimal mean difference of 0.01%, a standard deviation of 0.02% and V exhibiting the lowest compliance 0.52%, a standard deviation of 1.72%. D values displayed high compliance with a mean difference of 0.35%, and a standard deviation of 1.85%. The coverage index parameter was strongly supported (R²: 0.984). DNR values indicated close agreement with a mean difference of 0.01%, a standard deviation: of 0.10%. The average Gamma value was 99.91% with a standard deviation of 0.11%. : The agreement between treatment planning system and independent software solutions results validates treatment planning accuracy. This supports the method’s suitability for patient care and encourages wider adoption, ensuring quality assurance in clinical settings.
