Nimotuzumab y radioterapia en el tratamiento de tumores del tallo cerebral en niños y adolescentes
Texto completo:
HTMLResumen
Objetivos: Estimar el efecto de la asociación del tratamiento radiante con el anticuerpo monoclonal Nimotuzumab en la supervivencia de niños y adolescentes con tumores del tallo cerebral
Método: Estudio clÃnico no aleatorizado, analÃtico, longitudinal y prospectivo en una serie de 46 pacientes entre 2 y 18 años de edad que padecÃan de tumores del tallo cerebral, infiltrantes y difusos, desde enero de 2008 y en seguimiento hasta marzo de 2018. Todos se trataron con radioterapia, con dosis entre 5400 y 5980 cGrey, dosis diaria de 18 cGrey,y e irradiados de lunes a viernes. Mientras duró el tratamiento radiante recibieron Nimotuzumab, en la dosis de 150 mg/m2 de superficie corporal, luego semanal con 8 dosis, y finalmente mensual durante uno o dos años.
Resultados: Se alcanzó en la serie una supervivencia media de 18,4 meses, y una esperada de 42,9 % a 2 años y 35,5 % a 5 años, estabilizada hasta los 10 años.
Conclusiones: La combinación de la radioterapia y el anticuerpo monoclonal Nimotuzumab incrementa la supervivencia en los tumores cerebrales del tallo cerebral en niños y adolescentes y es bien tolerada, aun en periodos prolongados, e incluso en casos de recidiva.
