Background: Squamous cell carcinoma (SCC) of the head and neck ranks 7th among all malignancies in the world with a high mortality rate. Squamous cell carcinoma (SCC) of the head and neck arises from epithelial cells that occur in the oral cavity, pharynx and larynx. P16INK4a is a major member protein compound of the Ink4 family of CDK inhibitors. P16 overexpression correlates well with distant metastasis free survival (DMFS) in head and neck squamous cell carcinoma
Objective: To determine the relationship between P16INK4A expression and distant metastasis in head and neck squamous carcinoma patients.
Method: The research was carried out at Dr. Sardjito Hospital on head and neck squamous cell carcinoma patients in the period January 2014 to December 2020 until the minimum sample size was met. Data were processed using bivariate analysis to determine the relationship between P16INK4a expression and distant metastasiss. Next, analysis is carried out Cox regression to find out whether variabels were found that had an influence on distant metastasis free survival (DMFS).
Results: In this study, 32 samples were obtained, 6 samples (18.8%) had distant metastasiss (18.8%) and 26 samples (81.3%) had no distant metastasiss. The distribution of P16INK4a expression obtained positive results in 12 samples (37.5%) and negative results in 20 samples (62.5%). The results of bivariate analysis in this study showed that there was no significant relationship (P>0.05, RR <1 p=0,29)> 0.05.
Conclusion: P16INK4a expression did not have a significant relationship with the incidence of distant metastasiss. P16INK4a expression had no effect on distant metastasis free survival (DMFS). No single variabel was found that influenced the distant metastasis free survival (DMFS).
