THE CORRELATION OF MDR/P-gp PHENOTYPE AND DIFFERENTIATION OF OSTEOSARCOMA

Abstract

Recent experimental studies on osteosarcomas (OS) have postulated that similar to other malignancies, pglycoprotein (P-gp) positivity is directly correlated with differentiation. Therefore, it has been hypothesized that Pgp cannot be a marker of poor prognosis. In this study, the distribution of P-gp positivity in different areas of OSs with variable differentiation pathways is assessed and its relationship with differentiation is questioned. The cases, which have received the diagnosis of OS in our department between 1984-2000, were included in the study. A total of 337 sections were immunohistochemically stained for P-gp, which consisted of 81 primary surgical materials, 82 biopsies, 13 lung specimens, one axillary lymph node and one rib metastasis, and three local recurrence materials. The P-gp staining patterns were scored between 0 and 6 on a total of 544 areas with different differentiation pathways. Our results have shown that P-gp expression of OSs has no correlation with the matrix content and differentiation. Furthermore, the analysis of the histological subtypes did not present any differences in the staining patterns. İn conclusion, despite the previous reports demonstrating correlation of this protein with differentiation, İt appears that P-gp staining of OSs is an independent factor.
