Absence of human papillomavirus in oral cavity squamous cell carcinomas among Saudi patients.

This study aimed to examine the possible association of human papillomavirus (HPV) with oral cavity squamous cell carcinomas (OCSCCs) in Saudi Arabia. Forty-five paraffin-embedded tumor blocks that represent different subsets of OCSCCs between 2010 and 2014 were retrieved and histologically evaluated. The presence of high-risk HPV (16, 18, 31, and 33) was assessed by p16-immunohistochemistry followed by DNA detection using in situ hybridization technique.

Oral cancer prevention and early detection: knowledge and practice among Saudi Arabian healthcare practitioners.

Purpose: Despite the crucial role that healthcare practitioners (HCPs) have in preventing and detecting oral cancer (OC), studies suggest that dentists and physicians do not adequately detect early stage OC which is attributed to their attitude and knowledge. This Saudi Arabian study aims to assess HCP's knowledge and practice vis-à-vis OC's risk factors and patient evaluation.

Design/methodology/approach: A questionnaire was distributed to HCPs in six different Saudi Arabian settings.

Perceptions of healthcare practitioners in Saudi Arabia regarding their training in oral cancer prevention, and early detection.

Purpose: Healthcare practitioners (HCPs) have a major responsibility in the prevention and early detection of oral cancer (OC). Accordingly, adequate training in this area will positively enhance healthcare practitioners' accountability towards their patients. The present study was conducted in Saudi Arabia with the objective of assessing HCPs' opinion vis-a-vis OC prevention and early detection.
