Clinical applications for an inexpensive, microcomputer-based DNA-cytometry system

Some of the clinical capabilities of an inexpensive, microcomputer-based DNA-cytometry system are described. A variety of applications is illustrated: ploidy assessment, which provides significant information for the management of patients with tumors from almost any organ site; quality control of cytologic and histologic diagnoses; determination of tumor heterogeneity; monitoring of cell profile changes during therapy; and quantitation of immunocytochemical staining.
