Laser Therapy Effect as Preventive Measure for Oral Mucositis in Children With Hematological Malignancies

This study is a randomized, prospective, double-blinded trial ( patient \& outcome assessor) that will include acute Myeloid leukemia patients admitted to receive chemotherapy cycle between the age of 3 and 18years. These patients will be randomized by the Clinical Epidemiology unit using a computer-based method into two groups. Group I: will receive Low Level Laser Therapy by Diode laser (Sirrolaser Blue ™, USA) at 44 different points in the oral cavity for 5 consequent days from Day 1 to Day 5 of chemotherapy cycle along with the standard preventive protocol in the hospital. Group II: will receive a mock treatment which is the exact repetition of the treatment modality but without any laser emission beside the standard preventive protocol applied in the hospital. All patients will be assessed for oral mucositis grade using NCI-CTCAE scale V4 and WHO score on days 1,5,12,19 and 30 .
