Overview

In vitro study reveals sustained suppression of invasion in glioma spheroids via sequential photo-sonodynamic therapy, suggesting a promising strategy to prevent postoperative recurrence.

Key Points

To evaluate whether sequential 5-aminolevulinic acid-mediated photodynamic therapy followed by repetitive sonodynamic therapy prevents glioma cell invasion in a 3D culture model.
Embedded F98 glioma spheroids in a three-dimensional Matrigel migration assay and incubated them with 5-aminolevulinic acid.
Administered single-modality photodynamic therapy (PDT) or sonodynamic therapy (SDT), alongside a sequential protocol combining one PDT session followed by two repetitive SDT sessions 24 hours apart.
Measured cell migration distance from the spheroid edge into the surrounding matrix at 4 and 7 days post-implantation under 1% and 5% fetal bovine serum conditions.
Both photodynamic therapy and sonodynamic therapy independently produced dose-dependent reductions in cell invasion, but single-agent photodynamic therapy failed to maintain long-term inhibition of invasive recurrence.
Sequential photodynamic therapy followed by repetitive sonodynamic therapy achieved sustained and significant inhibition of glioma cell invasion compared to either modality alone, without causing prolonged spheroid cytotoxicity.
