Both Ro 03-8799 and misonidazole were administered to six patients before tumour sampling. Using similar doses, tumour concentrations of Ro 03-8799 were approximately double those of misonidazole. Examination of the data with regard to the relative sensitising efficiencies of these two compounds gives us, as a conservative estimate, a factor of 1.6 in favour of Ro 03-8799. From these observations it is predicted that, when given with radiotherapy in a 25-fraction course Ro 03-8799, is likely to be at least five times more effective as a hypoxic cell sensitiser than misonidazole.

D008297 Male Males
D008545 Melanoma A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world.

D008920 Misonidazole A nitroimidazole that sensitizes normally radio-resistant hypoxic cells to radiation. It may also be directly cytotoxic to hypoxic cells and has been proposed as an antineoplastic.
