TUMOR DIAGNOSIS BY RAPID DNA PLOIDY PATTERN ANALYSIS

细胞学和组织学样本中细胞核的DNA倍体模式

DNA ploidy patterns in cell nuclei from cytologic and histologic samples will be used to provide tumor diagnostic and prognostic information. Our rapid, computer-controlled, video-based microphotometer system allows the recording of DNA-ploidy patterns within minutes, with statistically valid sample sizes, thus making this valuable method practical as a routine clinical laboratory test. It is intended to standardize the methodology for this purpose, to assemble and examine a clinical database to correlate ploidy patterns with clinical implications, to establish objective measures for ploidy pattern evaluation, and to establish the sensitivity for the detection of aneuploidy. An inexpensive, microprocessor-based microscope attachment and graphic display has been designed as a prototype for a practical pathology laboratory instrument. (3)
