Background:
Oral squamous cell carcinoma (OSCC) is an aggressive epithelial malignancy. Diagnosis at an early stage is a key for successful cancer therapy. Development of sensitive, specific, and non-invasive tumor markers, especially, in serum, is needed. Midkine (MK) is a plasma-secreted multifunctional peptide which is a heparin-binding growth factor.
Materials And Methods:
Blood samples were collected from 20 patients with OSCC, 20 patients with oral premalignancy and 10 healthy controls. Only histologically proven oral cancer and precancerous patients were taken as test subjects. Healthy individuals without predisposing habits were selected. The Human Midkine ELISA kit (Biovendor,Czech Republic) was stored at 2-80C.
Statistical Analysis:
One way ANOVA was applied using SPSS software.
Results:
Midkine Concentration in Poorly differentiated was significantly higher than Well differentiated OSCC. Midkine Concentration in stage II was significantly higher than stage I. There was a very strong positive and significant correlation between severity of disease and Midkine concentration. Also there was a strong positive and significant correlation between histological grades of oral squamous cell carcinoma and Midkine concentration.
Interpretation And Conclusion:
MK is a soluble, secreted cytokine and can be quantitated in blood. This is a merit of any biomarker compared to biopsy, as sampling of blood is minimally invasive, convenient, inexpensive and can be performed frequently for detecting, monitoring and managing illness. Increased MK expression in tissues, blood and urine has a strong relationship with higher malignant potential. Serum MK concentration may serve for cancer screening and monitoring the prognosis of the disease.
