Misonidazole

08/01/1984 - "This implies that high LET killing is considerably more effective in this tumor system (hypoxic fraction of about 35%) than the hypoxic cell sensitization caused by misonidazole. "
09/01/1988 - "The major results were as follows: (1) patients who were old (70 to 80 years) fared as well as younger patients (P = 0.9198); (2) tumor site did not influence therapeutic outcome (P = 0.1100); (3) there was an insignificant difference in survival between patients with M0 and M1 disease (P = 0.7130); (4) radical surgery gave better survival; (5) misonidazole administered preoperatively was associated with worse survival (P = 0.0147); and (6) the histopathologic malignancy grading score system was very useful for prognostication--the tumor-host score in the operative specimen was the strongest of all analyzed predictive parameters. "
01/01/1987 - "Hydrogen-3-fluoromisonidazole diffused into tumors at a slower rate than misonidazole but it also cleared from normal tissues so that after 2 hr tumor-to-blood ratios favorable for imaging were achieved. "
10/01/1984 - "It was shown from this model that misonidazole should be effective for cancer which had a hypoxic fraction of more than 10%, and in which reoxygenation did hardly occur, and that the effect of misonidazole was not dependent on the size of dose per fraction for radioresistant cancer."
03/01/1984 - "These data suggest that misonidazole is effective in sensitizing hypoxic cells in the clinical dose range, and that it is directly cytotoxic to hypoxic tumor cells."

12/01/1983 - "It is already known that Misonidazole as a radiosensitizer is not so effective with the small doses of radiation that we generally use to treat human uterine cervical carcinoma by fractionated irradiation. "
11/01/1986 - "Regarding several positive phase II studies with misonidazole, some hopes had been placed in this study because at present the therapeutic situation in oesophagus carcinoma is extremely unsatisfactory. "
11/01/1986 - "[Esophageal carcinoma: the final results of a multicenter and controlled German study with misonidazole and radiation]."
10/01/1985 - "Between February 1979 and January 1982, a Phase II study of misonidazole as a radiosensitizer was performed in 34 patients with advanced carcinoma of the uterine cervix. "
10/01/1985 - "Radical irradiation and misonidazole in the treatment of advanced cervical carcinoma: results of a phase II trial."

03/17/1992 - "In direct comparison with misonidazole, DMM, at equimolar concentrations, showed dramatically reduced binding to cellular macromolecules under bioreductive conditions, both in vivo, using a liver perfusion system, and in vitro, using tissue culture cells incubated under extreme hypoxia. "
07/01/1991 - "Direct comparison of IVM versus F-MISO (2) another misonidazole type hypoxic cell marker, in several in vitro cell culture studies, indicates that IVM behaves in analogous fashion to F-MISO and has promise as a hypoxia imaging agent for SPECT."
01/01/2015 - "Preparation and Biodistribution of Technetium-99m-Labeled Bis- Misonidazole (MISO) as an Imaging Agent for Tumour Hypoxia."
01/21/2003 - "An example case of a base-of-tongue tumour which was imaged with the hypoxia tracer fluoro-misonidazole is presented, showing the excellent capability of IMRT to produce dose distributions that conform to spatially variable dose prescriptions."
01/15/2001 - "18F misonidazole scans detected hypoxia in 14 of 15 patients at baseline, with only one patient having detectable hypoxia at the end of treatment. "

01/01/2003 - "There is no indication of a treatment benefit with the addition of either hyperthermia or misonidazole. "
01/01/1995 - "Modification of radiation-induced chromosome damage and micronucleus induction in mouse bone marrow by misonidazole and hyperthermia."
05/01/1991 - "The addition of both hyperthermia and misonidazole to radiation more than overcame the relative resistance of the dim subpopulation to 10 Gy. These results indicate that misonidazole is a reasonable drug for use with hyperthermia and radiation to increase killing of hypoxic cells, but the decrease in cytotoxicity and radiosensitizing abilities of this agent observed under acidotic conditions could reduce the effectiveness of this treatment."
05/01/1991 - "Unexpectedly, exposure to misonidazole at 42 degrees C or 43 degrees C and pH 6.45 caused no significant increase in cytotoxicity over that attributable to hyperthermia alone. "
07/01/1987 - "Enhancement of misonidazole chemopotentiation by mild hyperthermia (41 degrees C) in vitro and selective enhancement in vivo."

04/01/1987 - "We tested the efficacy of the hypoxic cell sensitizer misonidazole in conjunction with intraoperative electron beam radiation therapy (IORT) and external beam irradiation in patients with locally advanced, nonmetastatic adenocarcinoma of the pancreas. "
07/15/1989 - "Modulation of prostaglandin biosynthesis in hypoxic murine mammary adenocarcinoma cells by misonidazole."
01/01/1989 - "Misonidazole, a clinically-effective 2-nitroimidazole hypoxic cell radiation sensitizer, and 12 4-nitro-5-sulfonatoimidazoles were tested in cultured human SW1116 colorectal adenocarcinoma cells for radiosensitizing efficiency. "
04/01/1981 - "The "chemosensitizing" properties of the radiosensitizer misonidazole (MISO) were examined in 2 tumour systems, murine Lewis lung carcinoma and human pancreatic adenocarcinoma xenografted into immune-suppressed mice, using a soft-agar colony assay to measure tumour-cell survival. "
07/15/1989 - "We have investigated the effects of misonidazole on the biosynthesis of prostaglandins (PGs) in a murine mammary adenocarcinoma cell line (No. 4526) under aerobic and hypoxic conditions in attempts to exploit modulation of PG levels under hypoxia as a means of improving therapeutic approaches for the treatment of solid tumors.
