Diffuse intrinsic brainstem gliomas have a bad prognosis, and short-term survival time. Radiotherapy has been the principal treatment, and chemotherapy has not improved outcome. The anti –EGFR monoclonal antibody Nimotuzumab combined with Radiotherapy was tested in a series of 41 children and adolescents with diffuse intrinsic pontine gliomas (DIPG) included between January 2008 and December 2015 and a follow-up till January 2021.They were irradiated in the Instituto Nacional de Oncologia y Radiobiologia, Havana, Cuba with a median dose of 54 Gy. Nimotuzumab was applied at a dose of 150 mg/m2, weekly during the period of irradiation, then every 2 weeks by 8 doses, and them monthly for 1,2 or more years. A response was observed in 87.8% of patients. Prolonged use of Nimotuzumab was feasible and well tolerated. Median age at diagnosis was 7 years old, median survival was 18.8 months. There were minor toxicities, only Grade I or II. Survival rate at 5 years was 34.1%, stablished till years or more. Two relapsing patients were re-irradiated. The combination of irradiation and Nimotuzumab is an option to increase survival in DIPG. |
