Oral mucosa cancer is a type of head and neck cancer that can affect any part of the oral cavity, including the lips, tongue, cheeks, and gums. It is a rare type of cancer, accounting for only about 3% of all cancer cases in the United States. However, if left untreated, it can be a severe and potentially life-threatening condition.
Diagnosis of oral mucosa cancer typically involves a physical examination, including a visual inspection of the mouth and throat, and a biopsy to confirm the presence of cancerous cells. Treatment options for oral mucosa cancer include chemotherapy, radiation therapy, surgery, or combination therapy.
The treatment of choice will depend on the stage and location of cancer and the patient’s overall health and preferences. Palliative care may also be an important aspect of managing oral mucosa cancer, especially in cases where cancer has spread or is advanced.
Epidemiology
Oral mucosa cancer is a rare type of cancer, accounting for only about 3% of all cancer cases in the United States. However, it is more common in specific populations, such as those who use tobacco and alcohol or are exposed to certain strains of the human papillomavirus (HPV). Men are also more likely to develop oral mucosa cancer than women, and the risk increases with age.
The incidence of oral mucosa cancer varies worldwide, with higher rates reported in certain regions, such as South and Southeast Asia, where betel quid chewing is common. In the United States, the incidence of oral mucosa cancer has remained stable in recent years, with about 53,000 new cases and 10,860 deaths reported in 2020.
Anatomy
Pathophysiology
Oral mucosa cancer develops when normal cells in the lining of the mouth or throat begin to grow and multiply uncontrollably, forming a mass or tumor. This can happen due to genetic mutations or changes in the DNA that control cell growth and division.
Risk factors, such as alcohol and tobacco use, exposure to certain strains of the human papillomavirus (HPV), poor oral hygiene, and chronic inflammation, can increase the likelihood of these genetic mutations. Once these mutations occur, the cancerous cells can invade nearby tissues and spread to other body parts, such as the lymph nodes or distant organs.
The pathophysiology of oral mucosa cancer can vary depending on the location and stage of cancer. Cancer can interfere with normal functions, such as swallowing and speaking, and may cause pain or discomfort in the affected area. Cancer can also cause weight loss, fatigue, and other systemic symptoms as it progresses.
Etiology
The exact cause of oral mucosa cancer is unknown, but various risk factors have been identified. Tobacco use, including smoking and smokeless tobacco products, is a major risk factor for oral mucosa cancer and accounts for a significant proportion of cases. Alcohol use is also a risk factor, particularly when combined with tobacco use.
Exposure to certain strains of the human papillomavirus (HPV) is another risk factor for oral mucosa cancer, particularly in the oropharynx. Other risk factors may include poor oral hygiene, chronic inflammation, and a weakened immune system. Some genetic factors may also play a role in developing oral mucosa cancer.
Not all individuals with these risk factors will develop oral mucosa cancer, and some individuals without any known risk factors may develop the disease. Early detection and treatment are crucial to improving outcomes in patients with oral mucosa cancer, regardless of the underlying cause.
Genetics
Prognostic Factors
Prognostic factors for oral mucosa cancer can help predict the likelihood of recurrence or survival after treatment. The cancer stage at diagnosis is the most important prognostic factor, with earlier stages associated with better outcomes.
Other factors that may affect prognosis include:
The location and size of the tumor.
The degree of invasion into nearby tissues.
The presence of lymph node involvement or distant metastases.
The patient’s age and overall health status.
Histologic grade, or the degree of differentiation of the cancer cells, can also provide important prognostic information.
Patients with smaller tumors, no lymph node involvement, and good overall health, are more likely to have better outcomes than those with larger or more advanced tumors. However, each patient’s prognosis can be affected by several factors.

Treatment Paradigm
The treatment paradigm for oral mucosa cancer depends on the stage and location of the cancer, and the patient’s overall health and preferences. According to the National Library of Medicine, treatment options for oral mucosa cancer may include:
Surgery: The surgical treatment paradigm for oral mucosa cancer typically involves the removal of the cancerous tissue, which the reconstruction of the affected area may follow. Surgery may be combined with radiation therapy or chemotherapy, depending on the extent of the cancer.
Chemoradiotherapy: Chemoradiotherapy is a treatment option for oral mucosa cancer involving chemotherapy and radiation therapy. This approach may be used in cases where surgery is not an option or to preserve organ function.
Monoclonal antibodies: Monoclonal antibody therapy is an emerging treatment approach for oral mucosa cancer that involves targeted antibodies to block specific proteins involved in cancer growth and survival. This treatment may be combined with chemotherapy or radiation therapy in certain cases.
Palliative care is an essential aspect of managing oral mucosa cancer, especially in cases where cancer has spread or is advanced. Palliative care focuses on relieving symptoms and improving the quality of life for the patient through pain management, symptom control, and supportive care.
