Anti-CD10 (56C6) expression in soft tissue sarcomas

Abstract

CD10 is known to be expressed in certain types of leukemia, in lymphomas and also in various types of carcinoma. However, data regarding CD10 expression in soft tissue sarcomas is scarce. Two hundred and two retrospective soft tissue sarcoma specimens were evaluated for CD10 expression immunohistochemically. The clinical records of these patients were reviewed, and clinical data was obtained for all patients. Our results showed that 90 of the 202 cases were found to express CD10. 72% of malignant fibrous histiocytomas, 45% of fibrosarcomas, 34% of rhabdomyosarcomas, 50% of leiomyosarcomas, 22% of liposarcomas, 72% of malignant peripheral nerve sheath tumors, and 0% of the primitive neuroectodermal tumors were positive for CD10. Nearly half of the soft tissue sarcomas were found to express CD10. Stronger CD10 expression was found in high grade sarcomas. (C) 2012 Elsevier GmbH. All rights reserved.
