Chemical-Drug-Free, Ionizing-radiation-Free, and
Metabolic-Interference-Free Glioblastoma Multiforme Therapy
Abstract
Although there have been numerous recent advancements in medicine, the
prognosis for glioblastoma multiforme (GBM), is still poor. The
blood-brain barrier (BBB) places restrictions on GBM treatment. To
enhance therapeutic effects, medicines must aggregate at the tumor site.
In this review, peptide-modified nanoplatforms were discussed as not
only do they cross the BBB but some like RVG29 could also accumulate
specifically in cerebral glioma tissue. The use of magnetic
nanoparticles in magnetic hyperthermia which heats the tumor tissues
under alternating magnetic fields was discussed. Its use alone and in
combination with other adjuvant therapies was analyzed. Using modified
Iron oxide nanoparticles, magnetic hyperthermia can also be used with T
1/T 2 MRI. Additionally, the use of
sonodynamic therapy as a novel and efficient non-invasive way of
treating cancer cells was examined. Moreover, research on photo
penetration via the brain’s tissues was discussed. In humans’ head
(scalp plus skull), the red/NIR (630-810 nm) light penetration ranged
from 0.2-10%. In addition, the superadditive treatment efficacy of
using Fe 3O 4 when combined with
photodynamic and photothermal therapy was discussed, it demonstrated
superior efficacy in eliminating glioma as compared to employing each
treatment modality alone or in combination. Finally, according to the
superadditive (i.e. ”1+1>2”) effect, and the studies
reviewed. It is believed combining rather safe therapies, such as MHCT,
PTT, and PDT with appropriate nanoplatforms that are coated with BBB and
GBM cells targeting ligands, Could result in enhanced GBM therapy and
MRI monitoring.
