Background: Oral squamous cell carcinoma (OSCC) is a multifactorial malignancy influenced by various genetic and environmental factors. Tobacco habits, human papilloma virus (HPV) infection, and p53 polymorphisms or mutations have been implicated in its etiology. Understanding their interplay can provide insights into OSCC risk assessment.
Materials And Methods: A case-control study was conducted among 300 OSCC patients and 300 age- and sex-matched controls. Data on tobacco use (smoking and smokeless), HPV infection status (detected via PCR), and p53 polymorphism/mutation (analyzed by sequencing) were collected. Statistical analysis included logistic regression to assess the associations and interactions among these variables.
Results: Among OSCC cases, 75% were tobacco users compared to 35% in controls. HPV prevalence was significantly higher in OSCC cases (30%) than controls (5%). P53 mutations were identified in 40% of OSCC cases compared to 10% in controls. Logistic regression revealed synergistic effects between tobacco use and HPV infection (OR 5.2, 95% CI 3.0-9.0) and additive effects with p53 mutations (OR 3.5, 95% CI 2.0-6.0).
Conclusion: Tobacco habits, HPV infection, and p53 polymorphisms/mutations independently and synergistically contribute to the risk of OSCC. Strategies focusing on tobacco cessation, HPV vaccination, and genetic screening may help mitigate OSCC risk in susceptible populations.

Defining physiology and methods to measure biological mechanisms is essential. Extensive datasets such as RNA sequencing are used with little analysis of the knowledge gained from the various methodologies. Within this work, we have processed publicly available NCBI RNAseq datasets using a combination of bioinformatics tools for the largest physiological organ, the skin.

Importance: Cervical screening guidelines in the US recommend that most females can exit routine screening at age 65 years following 2 recent consecutive negative cotest results (concurrent human papillomavirus and cytology tests). However, empirical data on the subsequent risks of cancer and cancer death in this subgroup of females are limited.
Objective: To estimate the risks of cervical cancer and cervical cancer death among females who meet the cotesting criteria to exit screening.

Human papillomavirus type 16 (HPV-16) is a key driver in the development of cervical carcinoma, with the integration of its genome into the host DNA marking a critical step in disease progression. Monitoring the physical state of HPV-16, particularly the transition from episomal to integrated forms, is essential for evaluating the risk of malignancy development in cervix. This study presents the development of a duplex electrochemical biosensor for the simultaneous detection of the E2 and E6 genes of HPV-16.

An interesting article in this issue of Läkartidningen argues for the benefit of a broad HPV vaccination with catch-up vaccination also for men, and sheds more light on HPV-related cancer in men. There has been an increase of HPV-related anal and oropharyngeal cancer in recent years, but no screening methods for these cancers have been implemented. A gender neutral catch-up vaccination would help to decrease the burden of oncogenic HPV in society, and would also be beneficial for females.
