Human papillomavirus (HPV) is one of the most common sexually transmitted infections worldwide. Exposure to HPV is very common, and an estimated 65%-100% of sexually active adults are exposed to HPV in their lifetime. The majority of HPV infections are asymptomatic, but there is a 10% chance that individuals will develop a persistent infection and have an increased risk of developing a carcinoma. The International Agency for Research on Cancer has found that the following cancer sites have a strong causal relationship with HPV: cervix uteri, penis, vulva, vagina, anus and oropharynx, including the base of the tongue and the tonsils. However, studies of the aetiological role of HPV in colorectal and esophageal malignancies have conflicting results. The aim of this review was to organize recent evidence and issues about the association between HPV infection and gastrointestinal tumours with a focus on esophageal, colorectal and anal cancers. The ultimate goal was to highlight possible implications for prognosis and prevention.

Viral infection plays a significant role in the development and progression of many cancers. Certain viruses, such as Human Papillomavirus (HPV), Epstein-Barr Virus (EBV), and Hepatitis B and C viruses (HBV, HCV), are well-known for their oncogenic potential. These viruses can dysregulate specific molecular and cellular processes through complex interactions with host cellular mechanisms.

Background: In the context of the World Health Organization's (WHO) 90-70-90 targets for accelerating cervical cancer elimination, we aimed to assess the impact of achieving these targets and altering intervention factors on cervical cancer elimination in China and their potential benefits from preventing other human papillomavirus (HPV)-related cancers.
Methods: We developed a sexual contact network-Markov model to simulate HPV transmission and the progression of HPV-related cancers (cervical, vaginal, vulvar, penile, anal, and oropharyngeal cancers). We projected the population impact of achieving 90-70-90 targets by 2030 on the overall HPV-related cancer burden in China during 2024-2100.

Penile cancer (PeCa) ranks as the 30th most prevalent cancer globally, predominantly affecting populations in developing countries. Phimosis and Human Papillomavirus (HPV) infection are recognized as the primary risk factors. Early-stage diagnosis typically warrants limited excision or non-invasive therapies.

Human papillomavirus (HPV)-negative head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer type in the world and is associated with an overall poor prognosis. The protein methyltransferase SET and MYND domain-containing 3 (SMYD3), which trimethylates H3K4, activates gene transcription and enhances several oncogenic pathways, including epithelial-mesenchymal transition and cell cycle related pathways, in various cancer types. It was also recently shown that SMYD3 is overexpressed in HPV-negative HNSCC, and represses the expression of type I IFN response genes, contributing to resistance to anti-PD-1 checkpoint blockade in this disease.

Despite the emergence of the first human papillomavirus vaccine, the incidence of cervical cancer is still responsible for more than 350,000 deaths yearly. Over the past decade, ecto-5'-nucleotidase (CD73/5'-NT) and extracellular adenosine (ADO) signalling has been the subject of many investigations to target cancer progression. In general, the adenosinergic axis has been linked to tumourigenic effects.
