title: Cytologic uniformity of breast cancer from different localizations: a pattern analysis study.
abstract: Using cytologic pattern analysis it is shown that regions of different histologic structure in one breast cancer are of cytologic homogeneity. The so-called PFORM -- the quotient of the total outline length of DNA-particles to the nuclear area -- gives an objective cytologic parameter which is independent of DNA content of cancer cells. This objective parameter together with the subjective cytologic parameters described earlier may be a better basis for describing the biologic behavior of breast cancer than histologic structure which is inhomogeneous very often in a lump.
