Hypofractionation dose of brachytherapy skin cancer stage I-II
By the linear-quadratic model, we developed a method of brachytherapy mode hypofractionation dose of skin cancer stage I-II. A single focal dose is 5.2 Gy, the total focal dose of basal cell carcinoma is 36.4 Gy, summing up to 7 fractions (α/β=10), squamous - 41.6 Gr in 8 fractions (α/β=6), biologically effective dose respectively is 55.3 Gr and 77.2 Gy. The method is characterized by low toxicity, high efficiency, provides a favorable cosmetic effect, significantly reduce the duration of treatment and reduce the total dose.
