The normal mucosa adjacent to colonic adenocarcinoma (marginal or transitional mucosa) has been shown to have subtle alterations of architecture, surface glycoproteins and proliferative activity. To evaluate possible changes in nuclear configurations in this marginal mucosa, a large set of cytometric features was evaluated using a computer-assisted video analysis system. Preliminary statistical analysis of the measurements identified six nuclear features useful for discriminating marginal mucosa nuclei from normal (control) mucosa nuclei: total optical density (OD), nuclear area, chromatin texture (from gray value cooccurrence matrix), chromatin coarseness, average OD of nuclear staining and peripheral tendency of the chromatin in the nucleus. An analysis of variance revealed that both patient-to-patient and gland-to-gland variation would limit the usefulness of any one feature as a screening tool. As a group, however, these six features should be investigated further as markers of preneoplastic changes in histologically normal-appearing mucosa.
