Abstract
Background: Children with high-grade glioma still have a poor prognosis despite the use of multimodal therapy including surgery, radiotherapy, and chemotherapy. New therapeutic strategies and methods evaluating such therapies are needed. Observation: Here we describe a child with anaplastic oligodendroglioma of the spinal cord who was unable to tolerate standard chemoradiotherapy and who had still-vital residual tumour during therapy. A good response was obtained with low-dose metronomic treatment containing vinblastine. The treatment was guided according to gradual response assessed using various positron-emission tomography tracers. Conclusions: Metronomic treatment guided by positron-emission tomography could be a reasonable option in some high-risk pediatric tumours.
