The aim of this study was to compare the percentage of hypoxic cells obtained with two methods: an in vitro colony assay and a new method based on immunodetection of a marker for hypoxic cells (NITP) which could be used in patients. These studies have been carried out using one rodent tumour EMT6 (a mammary carcinoma) and one human tumour HRT18 (a rectal adenocarcinoma). The hypoxic cell fraction...
Background and purpose: Solid tumours contain hypoxic cells which are resistant to radiotherapy. This study compares the efficacy of several strategies to counteract diffusion-limited hypoxia, or intermittent hypoxia in a fractionated regimen of 1 to 6 2 Gy.Materials and methods: Nicotinamide (250 mg/kg), perflubron emulsion (Oxygent TM ) (4 ml/kg), tirapazamine (SR4233) (0.10 mmol/kg)...
