As the RTOG scale is comparable to the CTCAE 4.03 system, this finding highlights the fact that maintaining the integrity of the irradiated skin with either mechanical protection or pharmacological properties of an extract, such as CSNF, may prevent damage of the basal skin layer [16].
CTCAE has graded thrombocytopenia into 4 levels [15]: grade 1 (75000 to 150,000 cells/mm3) grade 2 (50000-75000 cells/mm3), grade 3 (25000-50000 cells/mm3), and grade 4 (less than 25000/mm3).
