In vivo and in vitro measurements of P32-uptake in the ocular tissue in cases of malignant melanoma.

In vivo and in vitro measurements of radioactive phosphorus uptake after intravenous injection of P32 in 26 cases of malignant melanoma of the choroid is reported. The specific radioactivity of dissected ocular tissue after enucleation is described. No statistically significant relationship between the radioactive phosphorus uptake and the histologically differentiated cell type was found. It was possible to demonstrate the P32 uptake as a function of the mass of the tumor.
