CCN3 Proteins as a diagnostic marker in osteosarcoma patients: A case control study

Area of Science:

• Oncology
• Biochemistry
• Molecular Diagnostics

Background:

• Osteosarcoma is the most common primary bone cancer, particularly in children and adolescents.
• Early diagnosis remains a critical unmet need despite advancements in treatment.
• This study investigates CCN3 protein as a potential diagnostic marker for osteosarcoma.

Purpose of the Study:

• To analyze CCN3 protein expression in osteosarcoma patients.
• To correlate CCN3 expression levels with the clinical severity and grade of osteosarcoma.
• To evaluate CCN3 as a potential diagnostic biomarker for early osteosarcoma detection.

Main Methods:

• A case-control study involving 35 osteosarcoma patients and 10 healthy controls.
• Tissue samples analyzed for CCN3 protein expression using western blotting.
• Clinic-radiological examinations and AJCC grading were performed on patient samples.

Main Results:

• CCN3 protein expression was significantly upregulated in osteosarcoma tissues compared to controls (p<0.0001).
• No significant correlation was found between CCN3 protein expression levels and the different grades of osteosarcoma.
• Demographic parameters showed no significant differences between groups.

Conclusions:

• Upregulated CCN3 protein expression in osteosarcoma suggests its potential as a diagnostic biomarker.
• Further multi-centric studies are recommended to validate these findings and improve generalizability.
• CCN3's differential manifestation warrants further investigation for diagnostic utility in osteosarcoma.
