HPV-positive oropharyngeal cancer

HPV-positive oropharyngeal cancer is a subtype of oropharyngeal cancer that is associated with the Human papillomavirus (HPV). This type of cancer occurs in the oropharynx, which includes the back third of the tongue, the back of the throat, the tonsils, and the walls of the pharynx.

Etiology

HPV-positive oropharyngeal cancer is caused by an infection with HPV, specifically the HPV 16 subtype. The virus is transmitted through sexual contact, including oral sex. The risk of developing HPV-positive oropharyngeal cancer is higher in individuals who have had multiple sexual partners, have a history of oral HPV infection, or have a weakened immune system.

Clinical Presentation

Patients with HPV-positive oropharyngeal cancer may present with a sore throat, difficulty swallowing, hoarseness, unexplained weight loss, ear pain, or a lump in the neck. These symptoms may be similar to other conditions, so it is important to seek medical attention for a proper diagnosis.

Diagnosis

Diagnosis of HPV-positive oropharyngeal cancer involves a physical examination, review of the patient's medical history, and diagnostic tests. These tests may include a biopsy, imaging tests such as a CT scan or MRI, and a PET scan. In addition, a test for HPV may be performed on the biopsy sample to determine if HPV is the cause of the cancer.

Treatment

Treatment for HPV-positive oropharyngeal cancer depends on the stage of the cancer and the patient's overall health. Treatment options may include surgery, radiation therapy, chemotherapy, or a combination of these treatments. In some cases, targeted therapy or immunotherapy may be used.

Prognosis

The prognosis for HPV-positive oropharyngeal cancer is generally better than for other types of oropharyngeal cancer. This is because HPV-positive cancers are often more responsive to treatment and less likely to spread to other parts of the body.

Prevention

Prevention of HPV-positive oropharyngeal cancer involves reducing the risk of HPV infection. This can be achieved through vaccination against HPV, practicing safe sex, and regular screening for HPV.
