Expression of hormonal receptors in osteosarcomas of the jaw bones: clinico-pathological analysis of 21 cases

Background: Sexual hormones have an important role in many hormone-dependant tumors like breast and prostate carcinomas, and also a relationship has been found with bone metabolism and bone tumors. Some studies have demonstrated that the expression of hormonal receptors (HR) in osteosarcomas (OS) of long bones is associated with gender, histological grade, histological type, and possibly may be connection with pathogenesis and evolution. However, to our knowledge there are no studies of HR in osteosarcomas of craniofacial bones (OS-CF). Objectives: To assess the expression of hormonal receptors in OS-CF. Material and Methods: Twenty one cases of OS-CF were included in this study. Clinical o…
