Changes in blood-brain barrier permeability induced by radiotherapy: Implications for timing of chemotherapy? (Review)

van Vulpen, Marco, Kal, Henk, Taphoorn, Martin, El Sharouni, Sherif·2002·Oncology Reports

Abstract

The brain requires a stable internal environment, which is established by the integrity of the blood-brain barrier (BBB). The efficacy of chemotherapeutics in the treatment of brain malignancies is often hampered by the presence of the BBB. BBB disruption can be performed either by osmotic disruption, bradykinin or irradiation. Radiotherapy with doses of 20 to 30 Gy with fraction size of 2 Gy may be used to increase the permeability of the BBB. These radiation doses by themselves will not give rise to serious side effects or long-term complications. Disruption of the BBB by radiotherapy might have implications in the treatment of primary brain tumors, cerebral metastases, and prophylactic cranial irradiation in small cell lung cancer since irradiation will cause cell kill and may enhance the effect of chemotherapy. We present a review on the effects of irradiation on the BBB and subsequently discuss the potential value for therapeutic applications.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
