A disintegrin and metalloprotease 8 (ADAM8) is a trans-membrane protein, which is involved in cell adhesion, signaling and migration as well as the proteolytic cleavage of various substrates.
Endostatin is a potent inhibitor of angiogenesis.
ADAM8 and Endostatin have been associated with multiple malignancies.
However, their role in osteosarcoma is not fully elucidated.
Aim: To determine the expression of ADAM8 and endostatin in osteosarcoma and to study their correlation with different clinicopathological parameters and patients’ outcomes.
Material and methods: ADAM8 and endostatin expression were immunohistochemically evaluated in 61 primary osteosarcomas and 11 pulmonary metastatic osteosarcoma lesions.
Results: Among 61 primary osteosarcomas, ADAM8 was detected in 52 tumors (85.2%) and highly expressed in 33 cases (54.1%).
Positive endostatin expression was found in 28 tumors (45.9%).
Higher ADAM8 and decreased endostatin expression rates in metastatic lesions compared to primary osteosarcoma were found but these differences were not statistically significant (p= 0.086 & 0.558 respectively).
High ADAM8 expression score and positive endostatin expression were significantly correlated with tumor size, stage and distant metastasis (p< 0.05).
Survival analysis showed that high ADAM8 expression was associated with poor overall survival (OS) (p= 0.0002).
Multivariate analysis revealed that ADAM8 expression level was an independent prognostic parameter for the OS (p= 0.017).
