The highest-risk types are HPV 16 and 18; these are responsible for the vast majority of HPV-related cancers, including cancers of the cervix, vagina, vulva, penis, anus, and head and neck.
Another test is specific for DNA from HPV types 16 and 18, the two types that cause most HPV-associated cancers. A third test can detect DNA from several high-risk HPV types and can indicate whether HPV-16 or HPV-18 is present. A fourth test detects RNA from the most common high-risk HPV types.
An increased risk of HPV+OPC is observed more than 15 years after HPV exposure, [8] pointing to a slow development of the disease, similar to that seen in cervical cancer. Relative to HPV-OPC, the oncogenic molecular progression of HPV+OPC is poorly understood. [28] The two main viral oncoproteins of the high risk
The preferred screening for women aged 30–65 is "co-testing", which includes a combination of cervical cytology screening and HPV testing, every 5 years. [11] However, it is acceptable to screen this age group with a Pap smear alone every 3 years or with an FDA-approved primary high risk HPV test every 5 years. [11]
HPV testing can identify most of the high-risk HPV types responsible for CIN. HPV screening happens either as a co-test with the Pap smear or can be done after a Pap smear showing abnormal cells, called reflex testing. Frequency of screening changes based on guidelines from the Society of Lower Genital Tract Disorders (ASCCP).
Estimates place the worldwide risk of cancers from infectious causes at 16.1%. [1] Viral infections are risk factors for cervical cancer, 80% of liver cancers, and 15–20% of the other cancers. [2] This proportion varies in different regions of the world from a high of 32.7% in Sub-Saharan Africa to 3.3% in Australia and New Zealand. [1]
