OBJECTIVE: The purpose of this study was to investigate the prognostic impact of p53 and p16 expression in curettage material from patients with endometrial carcinoma. STUDY DESIGN: Preoperative curettage material from a population-based series of 236 endometrial carcinomas from Norway with long and complete follow-up was studied immunohistochemically for p53 and p16 expression. RESULTS: Pathologic expression of p53 and p16 was seen in 24% and 25%, respectively, and was significantly correlated with high International Federation of Gynecology and Obstetrics (FIGO) stage and serous/clear cell histologic subtypes. Pathologic p53 expression showed significant correlation with postmenopausal status, high grade, high tumor cell proliferation, and aneuploidy. Patients with normal expression had 85% 5-year survival compared with 51% and 50% when pathologic expression of p53 and p16, respectively. Five-year survival for patients with 2 pathologic markers was 13%, compared with 67% and 91% for 1 or no pathologic markers, respectively. CONCLUSION: Pathologic expression of p53 and p16 in curettage material identifies high-risk endometrial carcinoma patients with poor prognosis.
