Abstract 30P
Background
Oral squamous cell carcinoma (OSCC) represents one of the six most common cancers in the world. The identification of new prognostic markers could help clinicians explore the biological characteristics of OSCC and develop more personalized treatment plans for patients based on their risk factors. The discovery and study of new prognostic markers of OSCC may help improve treatment outcomes through more accurate and effective treatment strategies, ultimately leading to improved survival and quality of life in patients with OSCC. The aim of this study was to identify the prognostic value of CDKN2A and miRNAs, involved in its regulation as markers of OSCC.
Methods
In the present study we have results of the examination and treatment of 70 patients with stage II–IV OSCC. miR-10b and -155 and mRNA of CDKN2A in tumor samples of patients with OSCC was analyzed by real-time reverse transcription polymerase chain reaction. Detection of p16INK4a was performed by simultaneous immunohistochemical assessment in tumor cells.
Results
We found a strong correlation of studied miRNAs expression with lymph node metastasis (r=0.56 for miR-10b and 0.59 for miR-155). Also, there is no differences in miR-10b and -155 between p16INK4a+ and p16INK4a- samples. p16INK4a status does not affect the association of both miRNAs with lymph node metastases.
Conclusions
The results indicate the relation between miR-10b and -155 and the presence of lymph node metastases of patients with OSCC and thus they can be used as prognostic markers of the disease.
