The Possible Role of Human Papillomavirus Infection in the prognosis of Oral Squamous Cell Carcinoma in a Northern Israel Population

Summary

Background:

Several types of human papillomavirus (HPV) have been found to be associated with oral squamous cell carcinoma (OSCC). Still, the significance of HPV infection and its relationship to patient prognosis remains an important matter of debate.

Objectives:

To investigate the incidence of HPV infection in OSCC patients in northern Israel populations to determine its role in the etiology and prognosis of OSCC.

Methods:

OSCC tissues were gathered from the pathology departments at Rambam and Padeh medical centers in northern Israel. HPV DNA typing and immunohistochemistry for p16INK4A antibodies were conducted to evaluate their incidence in OSCC tissues. Statistical analysis regarding its expression in the different sub-populations (Jews, Arabs, Druze) was conducted using chi-square and Fisher’s exact tests.

Results:

The study included 82 patients: 53 men and 29 woman; median age 62.1 years; 54 Jews, 25 Arabs, and 3 Druze. The overall incidence of HPV expression was 45% (n=37). The median age of HPV-positive patients was 53 years vs. 65.8 in the negative group (P < 0.001). The 5 year overall survival of HPV-positive patients was not significantly higher than HPV-negative patients. A significant association was found between P16 expression and overall survival (log-rank P = 0.001).

Conclusions:

HPV infection in OSCC was not found to be significant in this study; however, P16 expression in the tumor tissue was found to be a positive prognostic factor for better survival.
