title: Growth fraction of tumors estimated by continuous labeling.
abstract: The labeling index of tumors, when labeled continuously, was analysed kinetically and theoretically with regard to the growth fraction. The increase in the labeling index was composed of three slopes and was affected largely by the growth fraction. A method to estimate the growth fraction from the labeling index was presented.
