MICROBEAM RADIATION THERAPY BOOST FOR THE TREATMENT OF GLIOBLASTOMA
To improve the treatment of high-grade glioma such as glioblastoma, the deadliest cancer of the central nervous system, the potential effect of Microbeam Radiation Therapy (MRT) in combination with conventional radiotherapy has been investigated. A significant improvement in tumour control and survival in rats bearing high-grade glioma was seen after using MRT as a boost after conventional radiation therapy.

order with the dynamics, a correlation between
the increase in local order and the slowing down
of the sample is found over a wide q range
(Figure 52b), matching recent predictions from
simulations . Dynamics slow down first at
the next-neighbour distance, while a higher
particle concentration, and thus higher degree of
local order, are needed at the medium range of
about 500 nm. Furthermore,
In conclusion, the XCCA method offers increased sensitivity to structural changes compared to conventional scattering methods and allows the verification of predictions from state- of-the-art simulation and theory. Moreover, with the advent of the next-generation X-ray sources, XCCA and XPCS studies can be applied over increased time- and length scales and can be extended to many different liquids.
Glioblastoma (GBM) is both the most common and most aggressive malignant tumour originating in the brain. Despite advances in healthcare and technology, patients with GBM have a grim prognosis. The current standard treatment includes surgery with maximum-safe resection, followed by adjuvant chemo- and
radiotherapy. The radiation protocol consists of 30 to 35 fractions of 1.8-2 Gy (58-60 Gy total dose) given over 6-7 weeks . Despite this heavy therapeutic treatment, the mean survival time remains as low as 15 months after diagnosis.
