The incidence of oropharyngeal squamous cell carcinomas (SCCs) is increasing and is believed to reflect changing sexual practices in recent decades. For this case-case comparative study, we collected medical and life-style information and data on sexual behavior from 478 patients treated at the head and neck clinic of a tertiary hospital in Brisbane, Australia. Patients were grouped as (i) oropharyngeal SCC (n = 96), (ii) oral cavity, larynx and hypopharynx SCC ("other HNSCCs," n = 96), (iii) other SCCs (n = 141), and (iv) other diagnoses (n = 145). We fitted multivariable logistic regression models to estimate odds ratios (ORs) and 95% confidence intervals (CIs) associated with lifestyle factors and sexual behaviors. Compared to the other three patient groups, the oropharyngeal SCC patients had overall more sexual lifetime partners (kissing, oral sex and sexual intercourse). Oropharyngeal SCC patients were significantly more likely to have ever given oral sex compared to the other three patient groups-93% of oropharyngeal SCC patients, 64% of other HNSCC patients, and 58% of patients with other SCC or other diagnoses. Oropharyngeal SCC patients were significantly more likely to have given oral sex to four or more partners when compared to patients with other HNSCC (odds ratio [OR] 11.9; 95% CI 3.5-40.1), other SCC (OR 16.6; 95% CI 5.3-52.0) or patients with other diagnoses (OR 25.2; 95% CI 7.8-81.7). The very strong associations reported here between oral sex practices and risks of oropharyngeal SCC support the hypothesis that sexually transmitted HPV infections cause some of these cancers.

Background: Squamous cell carcinoma (SCC) is the most common histological type in the oropharynx with high incidence and mortality. The Pi3K-AKT signaling pathway is important for understanding prognostic factors such as metastasis, which is involved in the aetiopathogenesis of cancer and is associated with angiogenesis, progression, and cell survival. The aim of this study was to evaluate the correlation of the Pi3K/AKT pathway with prognostic factors associated with oropharyngeal SCC, including overall survival.

Background: REV7 is a multifunctional protein involved in various biological processes, including DNA damage response. REV7 expression in human cancer cells influences sensitivity to DNA-damaging agents, and its high expression level is reportedly associated with a poor prognosis in many carcinomas. However, the significance of REV7 expression in human papillomavirus 16-negative oropharyngeal squamous cell carcinoma (OPSCC) remains unclear.
