Abstract

Nuclear deoxyribonucleic acid (DNA) ploidy studies with use of paraffin-embedded specimens were performed by flow cytometry on 52 adrenocortical carcinomas. Specimens were prepared by the combined techniques of Hedley and Vindeløv. Clinical course was obtained by chart review and follow-up examination. Nine (17%) tumors had a normal (diploid) DNA pattern, 13 (25%) were DNA tetraploid, and 30 (58%) were DNA aneuploid. The DNA aneuploid group was subdivided: 18 tumors with one stemline and 12 tumors with two stemlines of abnormal DNA cells. For tumors that were resected for cure, the 5-year Kaplan-Meier disease-free survival rates of the five patients with DNA diploid tumors and of the six patients with DNA tetraploid tumors were 80% and 33%, respectively. For 21 patients of whom 12 had one-stemline and nine had two-stemline DNA aneuploid tumors, the survival was 67% and 0%, respectively. Following palliative resection, the 4-year survival rates of the four patients with DNA diploid, seven with DNA tetraploid, five (omitting one with short follow-up) with one-stemline DNA aneuploid, and three with two-stemline DNA aneuploid tumors were 0%, 0%, 0%, and 33%, respectively. Although adrenocortical carcinoma is in general markedly aggressive, the addition of nuclear DNA ploidy studies may help to identify certain groups of patients who have a relatively favorable prognosis.
