Clinical value of ezrin expression in primary osteosarcoma

Area of Science:

• Oncology
• Molecular Biology
• Biochemistry

Background:

• Ezrin is a key membrane cytoskeletal linker protein.
• Ezrin is implicated in the metastasis of primary osteosarcoma.

Purpose of the Study:

• To investigate the relationship between ezrin expression and clinical parameters in osteosarcoma.
• To determine the prognostic value of ezrin expression in osteosarcoma patients.

Main Methods:

• Seventy patients with histologically confirmed, metastasis-free osteosarcoma were analyzed.
• Immunohistochemical staining (IHC) was used to assess ezrin expression in tumor specimens.
• Clinical parameters were retrospectively reviewed.

Main Results:

• Ezrin expression was observed in 55.7% of patients.
• Ezrin-positive patients showed higher rates of osteoblastic histology and elevated alkaline phosphatase (ALP) levels.
• Ezrin expression correlated with poorer response to neoadjuvant chemotherapy, increased recurrence rates, and significantly worse 5-year event-free survival (EFS) and overall survival (OS).

Conclusions:

• Ezrin expression, detected by IHC, is a negative prognostic factor for osteosarcoma survival.
• Identifying ezrin expression provides valuable prognostic information for managing primary osteosarcoma.
• Combined assessment of ezrin status and chemoresponsiveness offers refined prognostic insights.
