Proliferating cell nuclear antigen (PCNA) in high‐grade malignant fibrous histiocytoma : Prognostic value in 48 patients
Grading based on histopathologic features is used to predict survival in soft‐tissue sarcoma. However, variations in clinical behavior between tumors of the same grade motivate a search for additional factors that correlate with prognosis. Proliferating cell nuclear antigen (PCNA) is expressed in proliferating cells during the G 1 S and G 2 ‐phases. To evaluate a prognostic implication of PCNA, t
