Abstract
The presence of hypoxic cells in solid tumours and the potential significance of this for the long term efficacy of the radiotherapy of solid tumours has been recognised for over 30 years1. However, progress in the development of methods capable of giving visual evidence of the presence of hypoxic cells and the location of these cells within the tumour, together with a quantitative estimation of the extent of hypoxia, have been made only in the last decade. Of particular importance in this connection are experimental results which have shown that at least part of the molecule of the 2-nitroimidazole radiosensitizer, misonidazole (MISO) (1) is bound into hypoxic cells by metabolic processes and/or upon irradiation2; that certain 2-nitrofuran derivatives suffer a similar fate upon metabolism in hypoxic cells3; and that the kinetics of incorporation and patterns of distribution of the 2-C atom and the 2’-H atom of misonidazole in hypoxic cells are identical4.
