Quantitative morphology of primary and metastatic tumors: comparative studies on tissue sections.
Feulgen-stained tissue sections of 84 invasive ductal carcinomas of the breast (IDC), 30 colorectal adenocarcinomas (ACC), 30 gastric adenocarcinomas (ACG), 10 lymph node metastases of squamous cell carcinomas (SCC) and 11 lymph node metastases of malignant melanomas (MM) were investigated by image cytometry at a spatial resolution of 0.25 micron. At least 150 tumor cell nuclei were measured in each case. By means of multivariate statistical analysis the specificity of the nuclear image for different histological tumor types could be demonstrated in lymph node metastases of SCC and MM. Nuclear image analysis therefore may be a useful tool for pathologists in making the differential diagnosis on metastases of unknown primary tumors. For IDC, ACG and ACC the metastatic phenotype could be identified by nuclear image analysis of the primary tumors. The prognostic significance of the nuclear image has been proved in adenocarcinomas of the stomach. Features of chromatin structure played an important role in both the diagnosis of doubtful histological tumor types and the prediction of lymph node involvement or prognostic outcome.
