Vitronectin significantly influences prognosis in osteosarcoma.

Area of Science:

• Oncology
• Biochemistry
• Pathology

Background:

• Vitronectin (VN) is a multifunctional adhesive protein implicated in tumor progression, angiogenesis, and metastasis.
• Its prognostic value in osteosarcoma, a primary bone cancer, has not been previously investigated.

Purpose of the Study:

• To investigate the prognostic significance of Vitronectin (VN) expression in osteosarcoma.
• To determine if VN expression correlates with patient survival outcomes.

Main Methods:

• Immunohistochemistry was used to assess VN expression in tumor tissues from 67 osteosarcoma patients and 20 osteochondroma patients.
• Kaplan-Meier curves and COX regression models were employed to analyze the association between VN expression and progression-free survival (PFS) and overall survival (OS).

Main Results:

• Osteosarcoma tissues exhibited increased VN expression compared to benign osteochondroma tissues.
• High VN expression was significantly correlated with shorter PFS and OS in univariate and multivariate analyses.
• VN expression showed no association with patient gender, age, tumor size, histologic subtype, or tumor location.

Conclusions:

• Elevated Vitronectin (VN) expression in osteosarcoma tumor cells serves as an independent indicator of poor clinical prognosis.
• VN may represent a potential therapeutic target for improving outcomes in osteosarcoma patients.
