Oral and oropharyngeal squamous cell carcinomas (OSCC and OPSCC) represent the majority of head and neck squamous cell carcinomas (HNSCC). Human papillomavirus (HPV

Human papillomavirus (HPV

AmpFire is an isothermal amplification real-time fluorescent HPV detection assay, developed in the USA (Atila BioSystems, Inc., Mountain View, CA), which detects HPV directly from clinical samples. No DNA extraction step is required [8] (https://atilabiosystems.com/multiplex-high-risk-hpv-by-fluorescent-detection/).

) is an important etiologic factor together with Epstein-Barr virus

Epstein-Barr virus

The Epstein–Barr virus (EBV), formally called Human gammaherpesvirus 4, is one of the nine known human herpesvirus types in the herpes family, and is one of the most common viruses in humans. EBV is a double-stranded DNA virus. It is best known as the cause of infectious mononucleosis ("mono" or "glandular fever").

(EBV).

Is squamous cell carcinoma caused by a virus?

Squamous cell carcinomas (SCC) of the larynx and hypopharynx are strongly associated with smoking and drinking habits while nasopharyngeal SCC as well as some oropharyngeal SCC are caused by a viral infection involving Epstein - Barr virus (EBV) and Human Papillomavirus (HPV), respectively.

Is squamous cell cancer HPV?

There are many types of HPV. HPV can cause cancer, warts or have no effect. HPV is very common in the U.S. Over 20 million Americans have some type of genital or oral HPV infection. In some people, oral HPV infection leads to HPV-OSCC (HPV-positive oropharyngeal squamous cell cancer) after many years.

What is squamous cell cancer caused by?

Most squamous cell carcinomas of the skin result from prolonged exposure to ultraviolet (UV) radiation, either from sunlight or from tanning beds or lamps. Avoiding UV light helps reduce your risk of squamous cell carcinoma of the skin and other forms of skin cancer.

Which squamous cell carcinoma is HPV related?

Abstract. Human papillomavirus (HPV) can infect the tonsillar tissues of the oropharynx and is associated with oropharyngeal squamous cell carcinoma. This article provides an overview to guide primary care providers in screening patients for oropharyngeal cancer and making appropriate referrals.

What is Squamous Cell Cancer? - Squamous Cell Cancer Explained [2019] [Dermatology]

Does HPV 16 cause squamous cell carcinoma?

High-risk human papillomavirus (HR-HPV) is a causative agent for an increasing subset of oropharyngeal squamous cell carcinoma. HPV 16 accounts for 90% of cases.

How do you get HPV squamous cell carcinoma?

Risk Factors

Oropharyngeal cancers associated with HPV have risk factors such as more number of sexual partners, oral-genital sex, and oral-anal sex. Marijuana use is an independent risk factor for HPV-positive HNSCC, and the risk increases with the intensity, duration, and cumulative years of marijuana smoking.

Who is most susceptible to squamous cell carcinoma?

People assigned male at birth (AMAB) are about two times more likely to develop squamous cell carcinoma. People over the age of 50 are most likely to get SCCs, but the incidence has been rising in people younger than 50.

Can stress cause squamous cell carcinoma?

Previous studies using the same tumor model described here, had shown that chronic stress increases susceptibility to squamous cell carcinoma (SCC) by suppressing protective immunity and increasing regulatory/suppressor T cells within the tumor microenvironment [25].

What are the warning signs of squamous cell carcinoma?

Can a virus cause skin cancer?

Three pathogenic human viruses associated with skin neoplasms are described: human papilloma virus (HPV), Kaposi's sarcoma (KS)-associated herpesvirus and human T-cell leukemia virus type 1. HPV was linked to squamous cell carcinoma (SCC) of the skin after its role in SCC of the cervix has been discovered.

Which HPV causes skin cancer?

Two types of HPV—HPV 16 ³⁰ and HPV 38 ³¹ —have been associated with melanoma in recent clinical cases.

Is skin cancer a virus or bacteria?

Merkel cell carcinoma (MCC) is a rare and very dangerous type of skin cancer. About 80 percent of the 3,000 cases of MCC diagnosed in the U.S. each year are caused by a polyomavirus. This common virus lives in the skin of most people, without signs and symptoms, and without ever developing into MCC.

What chemicals can cause squamous cell carcinoma?

Environmental toxins – Chemical burns and exposure to certain pollutants, such as tobacco smoke, motor vehicle exhaust and arsenic (which may be found in soil, water and air) can cause skin damage that leads to squamous cell carcinoma.

What virus is most responsible for oral tongue squamous cell carcinoma?

Of these, HPV and herpes have been the most thoroughly studied and are now considered to be the most likely “synergistic viruses” involved in human oral cancer. The herpes viruses most often linked to oral cancer are the Epstein-Barr virus (EBV), human herpes virus- (HHV-) 8, and cytomegalovirus (CMV) [9].

Which viral type is most responsible for oral tongue squamous cell carcinoma?

HPV 16 and 18 seem to be the most important viruses responsible for tumourigenesis and can be found in pre-malignant and malignant lesions of the oral cavity in up to 80% of cases (64). HPV is a risk factor for head and neck cancer, of which approximately 25% are infected with HPV (65).

How quickly does squamous cell carcinoma spread?

Squamous cell carcinoma rarely metastasizes (spreads to other areas of the body), and when spreading does occur, it typically happens slowly. Indeed, most squamous cell carcinoma cases are diagnosed before the cancer has progressed beyond the upper layer of skin.

Can squamous cell carcinoma cause other cancers?

Epidemiological studies suggest that individuals with basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) of the skin are more likely to develop other malignancies; however, the factors responsible for this are unknown.

What are five of the risk factors for basal and squamous cell carcinoma?

Does squamous cell carcinoma run in families?

Inheritance. HNSCC is generally not inherited; it typically arises from mutations in the body's cells that occur during an individual's lifetime. This type of alteration is called a somatic mutation. Rarely, HNSCC is found in several members of a family.

How do you prevent squamous cell carcinoma from coming back?

What organs does squamous cell carcinoma affect?

Squamous cell carcinoma (SCC) is the second most common form of skin cancer. It's usually found on areas of the body damaged by UV rays from the sun or tanning beds. Sun-exposed skin includes the head, neck, chest, upper back, ears, lips, arms, legs, and hands. SCC is a fairly slow-growing skin cancer.

Can a man give a woman HPV?

The virus can be passed on between sexual partners of any gender. However, the virus will be less widespread among younger women who have benefited from the school vaccination programme. Because fewer men and boys have been vaccinated, men who have sex with other men may generally be more at risk of HPV transmission.

Which HPV causes head and neck cancers?

[3], HPV DNA has been detected by polymerase chain reaction (PCR) in head and neck squamous cell carcinoma arising from various anatomic sites. HPV16 is the predominant HPV type, accounting for 90% of HPV DNA-positive HNSCCs.

What are the symptoms of HPV in females?
