- The treatment-related cumulative cutaneous side effects were graded according to CTC 3.0 and documented for both radiation courses. Since the first radiation treatment was performed before the definition of CTC criteria, all data from medical charts were reviewed and converted into CTC 3.0 criteria to compare maximal occurred cumulative toxicity at first and second radiation courses. Maximal cumulated late toxicity of the first radiation course was assessed at last follow-up before treatment or at baseline examination before re-treatment.
