HPV+OPC presents in one of four ways: as an asymptomatic abnormality in the mouth found by the patient or a health professional such as a dentist; with local symptoms such as pain or infection at the site of the tumor; with difficulties of speech, swallowing, and/or breathing; or as a swelling in the neck (if the cancer has spread to lymph nodes).
Oropharyngeal cancer, [1] [2] [3] also known as oropharyngeal squamous cell carcinoma and tonsil cancer, [1] is a disease in which abnormal cells with the potential to both grow locally and spread to other parts of the body are found in the oral cavity, in the tissue of the part of the throat that includes the base of the tongue, the tonsils, the soft palate, and the walls of the pharynx.
HPV-positive oropharyngeal cancer generally has a better outcome than HPV-negative disease, with a 54% better survival rate, [18] but this advantage for HPV-associated cancer applies only to oropharyngeal cancers. [19] People with oropharyngeal carcinomas are at high risk of developing a second primary head and neck cancer. [20]
Esophageal cancer may be due to either esophageal squamous-cell carcinoma (ESCC) or adenocarcinoma (EAC). SCCs tend to occur closer to the mouth, while adenocarcinomas occur closer to the stomach. Dysphagia (difficulty swallowing, solids worse than liquids) and painful swallowing are common initial symptoms.
Esophageal cancer (lower part) as a result of Barrettʼs esophagus. Male predominance is particularly strong in this type of esophageal cancer, which occurs about 7 to 10 times more frequently in men. [25] This imbalance may be related to the characteristics and interactions of other known risk factors, including acid reflux and obesity. [25]
The stages of oropharyngeal cancer are as follows: [23] • Stage 0 (carcinoma in situ): This stage indicates a good prognosis as most patients with stage 0 survive for a long period without the requirement of an intensive treatment. Although, the patient must cease smoking as it can increase the risk of developing a new cancer.
Smoking cigarettes had the largest impact on cancer rates, accounting for nearly 20% of cancers in 2019, meaning that as many as 206,550 cases and 103,000 deaths could have been prevented if all ...
Oral cancer has an overall 5 year survival rate of 65% in the United States as of 2015. [4] This varies from 84% if diagnosed when localized, compared to 66% if it has spread to the lymph nodes in the neck, and 39% if it has spread to distant parts of the body. [4] Survival rates also are dependent on the location of the disease in the mouth. [16]
