High-LET radiation combined with oxaliplatin induce autophagy in U-87 glioblastoma cells.

Modern protocols of concomitant chemo/radiotherapy provide a very effective strategy to treat certain types of tumors. High-linear energy transfer (LET) radiations, on the other hand, have an increased efficacy against cancer with low radiosensibility and critical localization. We previously reported that oxaliplatin, a third generation platinum drug, was able to reinforce the cytotoxicity of an irradiation by fast neutrons towards human glioblastoma U-87 cells in culture.
