Hypofractionated stereotactic radiotherapy with the hypoxic sensitizer AK-2123 (sanazole) for reirradiation of brain metastases: a preliminary feasibility report.
Reirradiation is a challenging field in the treatment of recurrent brain metastases. Because of the elevated risk of radiation toxicity due to previous irradiation, only a limited dose is prescribed. To enhance radiosensitivity, in the present analysis six patients received hypofractionated stereotactic radiotherapy (hSRT) with daily oral administration of the hypoxic sensitizer AK-2123 (sanazo...

-5-Phenoxysulphonyl-l-methyl-4-nitroimidazole (NSC 38087) can act as a sensitizer of hypoxic mammalian cells to radiation in vitro. The degree of sensitization achieved is greater than would be predicted from the drug's electron affinity. Cytotoxicity studies have shown that 5pM NSC 38087 can reduce the surviving fraction of log-phase V79 cells in air at 37°C to 10-2 after 2 h exposure. This to...
متن کاملSafety of Systemic Acridine Orange Administration with Low-dose Radiation in Mice
Acridine orange (AO) is a known radiation sensitizer, and concomitant local administration of AO and irradiation (5 Gy) after cytoreductive surgery results in good local control of musculoskeletal sarcomas in humans. Local administration of AO solution into the surgical field can act directly on residual tumor cells, and it is thought that systemic administration of AO may affect tumor cells in...
متن کاملLow Power He:Ne Laser Radiation in Killing Photosensitized Helicobacter pylori in Vitro
Four photosensitizers were used to test inhibitory effect of Helicobacter pylori bacteria using low power helium: neon red laser radiation. Biopsies were collected from 176 patients and H. pylori were isolated, identified and bacterial suspension was prepared. Samples of this suspension were mixed with various low concentrations of the test sensitizer. The mixture samples were exposed to differ...
متن کاملEarly toxicity of moderate hypofractionated volumetric modulated Arc radiotherapy for localized prostate cancer
Background: Based on the radiation biology model of prostate cancer, hypofractionated radiotherapy can improve the treatment outcomes without increasing toxicity. Although hypofractionated radiotherapy is implemented over a short period of time, it is more convenient and cheaper compared with conventional fractionated treatment. The aim of this study was to investigate the early toxicity of mod...
