Dr. Morrow’s Show Notes

What are cancers of the head and neck?

• • o Cancers that are known collectively as head and neck cancers 
    •  usually begin in the squamous cells that line the mucosal surfaces of the head and neck 
      • • (for example, those inside the mouth, throat, and voice box). 
    •  These cancers are referred to as squamous cell carcinomas of the head and neck. 
      • • Head and neck cancers can also begin in the salivary glands, sinuses, or muscles or nerves in the head and neck, 
        • o but these types of cancer are much less common than squamous cell carcinomas (1, 2).
  • o Cancers of the head and neck can form in the:
    •  Oral cavity: Includes the lips, the front two-thirds of the tongue, the gums, the lining inside the cheeks and lips, the floor (bottom) of the mouth under the tongue, the hard palate (bony top of the mouth), and the small area of the gum behind the wisdom teeth.

• • •  Throat (pharynx): The pharynx is a hollow tube about 5 inches long that starts behind the nose and leads to the esophagus. It has three parts: the nasopharynx (the upper part of the pharynx, behind the nose); the oropharynx (the middle part of the pharynx, including the soft palate [the back of the mouth], the base of the tongue, and the tonsils); the hypopharynx (the lower part of the pharynx).

• • •  Voice box (larynx): The voice box is a short passageway formed by cartilage just below the pharynx in the neck. The voice box contains the vocal cords. It also has a small piece of tissue, called the epiglottis, which moves to cover the voice box to prevent food from entering the air passages.

• • •  Paranasal sinuses and nasal cavity: The paranasal sinuses are small hollow spaces in the bones of the head surrounding the nose. The nasal cavity is the hollow space inside the nose.

• • •  Salivary glands: The major salivary glands are in the floor of the mouth and near the jawbone. The salivary glands produce saliva. Minor salivary glands are located throughout the mucous membranes of the mouth and throat.

• • • • If a squamous cell carcinoma of the head and neck is going to spread, 
  • o it almost always does so locally and/or to the lymph nodes in the neck. 
    •  Sometimes, cancerous squamous cells can be found in the lymph nodes of the upper neck when there is no evidence of cancer in other parts of the head and neck, possibly because the original primary tumor is too small. When this happens, the cancer is called metastatic squamous cell carcinoma with unknown (occult) primary. 

What causes cancers of the head and neck?

• • •  Alcohol and tobacco use
  • o (including secondhand smoke and smokeless tobacco, sometimes called “chewing tobacco” or “snuff”) are the two most important risk factors for head and neck cancers, especially cancers of the oral cavity, hypopharynx, and voice box (3–7). 
    •  People who use both tobacco and alcohol are at greater risk of developing these cancers than people who use either tobacco or alcohol alone (8, 9). 
    •  Most head and neck squamous cell carcinomas of the mouth and voice box are caused by tobacco and alcohol use (8).
    •  Infection with cancer-causing types of human papillomavirus (HPV), especially HPV type 16, 
  • o is a risk factor for oropharyngeal cancers that involve the tonsils or the base of the tongue. 
    •  In the United States, the incidence of oropharyngeal cancers caused by HPV infection is increasing, while the incidence of oropharyngeal cancers related to other causes is falling. 
      • • About three-quarters of all oropharyngeal cancers are caused by chronic HPV infection. 
      • • Although HPV can be detected in other head and neck cancers, it appears to be the cause of cancer formation only in the oropharynx. The reasons for this are poorly understood.
      •  Other known risk factors for specific cancers of the head and neck include the following:
  • o Paan (betel quid). The use of paan (betel quid) in the mouth, a common custom in Southeast Asia, is strongly associated with an increased risk of mouth cancers  

• • o Occupational exposure. Occupational exposure to wood dust is a risk factor for nasopharyngeal cancer (17, 18). Certain industrial exposures, including exposures to asbestos and synthetic fibers, have been associated with cancer of the voice box, but the increase in risk remains controversial (19). People working in certain jobs in the construction, metal, textile, ceramic, logging, and food industries may have an increased risk of cancer of the voice box (20). Industrial exposure to wood dust, nickel dust, or formaldehyde is a risk factor for cancers of the paranasal sinuses and nasal cavity 

• • o Radiation exposure. Radiation to the head and neck, for noncancerous conditions or cancer, is a risk factor for cancer of the salivary glands (24–26).

• • o Epstein-Barr virus infection. Infection with the Epstein-Barr virus is a risk factor for nasopharyngeal cancer (27) and cancer of the salivary glands (28, 29).

• • o Ancestry. Asian ancestry, particularly Chinese ancestry, is a risk factor for nasopharyngeal cancer (17, 18).

• • o Underlying genetic disorders. Some genetic disorders, such as Fanconi anemia, can increase the risk of developing precancerous lesions and cancers early in life (30).

What are head and neck cancer symptoms?

• •  Head and neck cancer symptoms may include a lump in the neck or a sore in the mouth
  • o or the throat that does not heal and may be painful, a sore throat that does not go away, difficulty in swallowing, and a change or hoarseness in the voice. These symptoms may also be caused by other, less serious conditions. It is important to check with a doctor or dentist about any of these symptoms.
  •  Symptoms of cancers in specific areas of the head and neck include:
  • o Oral cavity. A white or red patch on the gums, the tongue, or the lining of the mouth; a growth or swelling of the jaw that causes dentures to fit poorly or become uncomfortable; and unusual bleeding or pain in the mouth.

• • o Throat (pharynx). Pain when swallowing; pain in the neck or the throat that does not go away; pain or ringing in the ears; or trouble hearing.

• • o Voice box (larynx). Trouble breathing or speaking, pain when swallowing or ear pain.

• • o Paranasal sinuses and nasal cavity. Sinuses that are blocked and do not clear; chronic sinus infections that do not respond to treatment with antibiotics; bleeding through the nose; frequent headaches, swelling or other trouble with the eyes; pain in the upper teeth; or problems with dentures.

• • o Salivary glands. Swelling under the chin or around the jawbone, numbness or paralysis of the muscles in the face, or pain in the face, the chin, or the neck that does not go away.

How common are head and neck cancers?

• •  Head and neck cancers account for nearly 4% of all cancers in the United States (31).
  • o These cancers are more than twice as common among men as they are among women (31). 
    •  Head and neck cancers are also diagnosed more often among people over age 50 than they are among younger people.
    •  Researchers estimated that more than 68,000 men and women in the United States would be diagnosed with head and neck cancers in 2021. 
  • o Most will be diagnosed with mouth, throat, or voice box cancer. 
  • o Paranasal sinus and nasal cavity cancer and salivary gland cancer are much less common.

How can I reduce my risk of developing head and neck cancers?

• •  People who are at risk of head and neck cancers―particularly those who use tobacco―should talk with their doctor about ways to stop using tobacco to reduce their risk.
  •  Avoiding oral HPV infection can reduce the risk of HPV-associated head and neck cancers. In June 2020, the Food and Drug Administration granted accelerated approval of the HPV vaccine Gardasil 9 for the prevention of oropharyngeal and other head and neck cancers caused by HPV types 16, 18, 31, 33, 45, 52, and 58 in persons aged 9 through 45 years. 
  •  Although there is no standard or routine screening test for head and neck cancers, dentists may check the oral cavity for signs of cancer during a routine checkup.

How are head and neck cancers treated?

• •  Head and neck cancer treatment can include 
  • o surgery,
  • o radiation therapy, chemotherapy, 
  • o targeted therapy, 
  • o immunotherapy, 
  • o or a combination of treatments. 
  • o The treatment plan for an individual patient depends on a number of factors, including the location of the tumor, the stage of the cancer, and the person’s age and general health.

• •  Research has shown that patients with HPV-positive oropharyngeal tumors have a much better prognosis and higher chance of complete cure than those with HPV-negative tumors following the same treatment (32). 
  • o Because of this, ongoing clinical trials are investigating whether patients with HPV-positive cancers can be treated with less intensive regimens, such as less intensive radiation or immunotherapy.

What are the side effects of head and neck cancer treatment?

• •  Surgery for head and neck cancers may affect the patient’s ability to chew, swallow, or talk. 
  • o The patient may look different after surgery, and the face and neck may be swollen. 
  • o The swelling usually improves with time. However, if lymph nodes are removed, the flow of lymph in the area where they were removed may be slower and lymph could collect in the tissues (a condition called lymphedema), causing additional swelling that may last for a long time.
  •  Head and neck lymphedema may be visible or internal. 
  • o In most cases, it can be reversed, improved, or reduced if treated promptly. 
  • o Patients with untreated lymphedema may be more at risk of complications such as cellulitis, or an infection of the tissues. Untreated cellulitis, if severe, can be dangerous and could lead to further swallowing or breathing difficulties.
  •  After a laryngectomy (surgery to remove the voice box) or other surgery in the neck, 
  • o parts of the neck and throat may feel numb because nerves have been cut. If lymph nodes in the neck were removed, the shoulder and neck may become weak and stiff.
  •  Patients who receive radiation to the head and neck may experience side effects during and for a short while after treatment, including redness, irritation, and sores in the mouth; 
  • o a dry mouth or thickened saliva; 
  • o difficulty in swallowing; 
  • o changes in taste; 
  • o or nausea. 
  • o Radiation may also cause loss of taste, which may decrease appetite and affect nutrition, and earaches (caused by the hardening of ear wax). Patients may also notice some swelling or drooping of the skin under the chin and changes in the texture of the skin. The jaw may feel stiff, and patients may not be able to open their mouth as wide as before treatment.
  •  Although side effects will improve slowly over time in many patients, others will experience long-term side effects of surgery or radiation therapy, including difficulty swallowing, speech impairment, and skin changes (33).
  •  Patients should report any side effects to their doctor or nurse and discuss how to deal with them.
