Abstract Thymomas are the most common anterior mediastinal masses. Malignant potential and prognosis are unrelated to histologic appearance. Deoxyribonucleic acid (DNA) flow cytometry is of prognostic significance in a variety of tumors. We reviewed the records of 35 patients who on pathologic examination had a thymoma or thymic carcinoma. Flow cytometric studies, including DNA indices (ploidy) and S phase fraction, were done on paraffin block specimens from 31 patients. We believe this is the first report of DNA flow cytometric studies in thymic pathology. Mean survival was 63.5 ± 13.3 months for patients with benign thymomas, 10.5 ± 4.6 months for patients with malignant thymomas, and 19.3 ± 4.1 months for patients with thymic carcinomas. Patients with benign thymomas lived significantly longer than those with malignant thymomas (P = .001) and thymic carcinomas (P = .03). DNA flow cytometry demonstrated four aneuploid tumors (two benign thymomas and two malignant thymomas). All thymic carcinomas were diploid. There was no statistically significant difference among the groups. The mean S phase fraction was 15.22% for benign thymomas, 11.15% for malignant thymomas, and 14.31% for thymic carcinomas. No statistically significant difference was found among the groups. We conclude that flow cytometry is not a useful guide to malignant potential or prognosis in thymomas and thymic carcinomas.
