This study investigated a technique of eliminating proton spots (SpotDelete) in the 0.5 cm skin rind when using PBS PT for breast cancer. In the SpotDelete group (n = 27), the incidence rate of grade 1 and 2 acute radiation dermatitis was 67% and 37%, respectively. There were 0 instances of grade 3 dermatitis observed. In the cohort (n = 28) that didn’t use the SpotDelete technique, grade 1, 2, and 3 dermatitis accounted for 57%, 36%, and 7% of the cases, respectively. The authors suggested the SportDelete reduced the severity and onset of radiation dermatitis.
