Elevation of preciseness of diagnostics by the analysis of mathematic connections between estrogen and progesteron receptors in breast tumours with respect to the complicating factors

Abstract

Whole-group dependences of estrogen and progesterone receptors (ER and PR) on different factors or mutual dependence (ER/PR) can serve as diagnostic, therapeutic, or prognostic indicators or to the correction of e.g. incorrect stage of menstruation cycle on ER or PR or serve for the interlaboratory control
