Objective To evaluate the prognostic signifi cance of p16, Ki-67, p63, and cytokeratin (CK) 17 expression determined by immunohistochemical staining in cervical intraepithelial neoplasia (CIN) 1. Methods Biopsy tissue samples from 33 patients diagnosed with CIN 1 were stained immunohistochemically for p16, Ki-67, p63, and CK17. The staining results were correlated with the clinical course of the disease. Results Seventeen of 18 (94.4%) p16-negative patients experienced regression, and only 1 patient (5.6%) developed persistent disease. Fifteen of the 16 (93.8%) Ki-67-negative patients experienced regression, and 1 patient (6.3%) developed persistent disease. Negative p16 and Ki-67 expression correlated signifi cantly with disease regression (P =0.004 and P =0.017, respectively). Fourteen of 15 (93.3%) patients negative for both p16 and Ki-67 experienced regression, and 1 patient negative for both p16 and Ki-67 (6.7%)developed persistent disease. The expression levels of p63 and CK17 were not signifi cantly associated with disease regression or persistence (P =0.149 and P =0.642, respectively). Ten of the 13 (76.9%) p16-positive patients had a high-risk HPV infection. Highrisk HPV infection was signifi cantly associated with p16 expression (P =0.049). Conclusion CIN 1 with p16- or Ki-67-negative immunohistochemical staining was associated with spontaneous disease regression. The p63and CK17 expression patterns were not related to the behavior of CIN 1.
