Jaw Cancer: A Rare but Serious Type of Head and Neck Cancer

Jaw cancer, also known as oral cavity cancer, is a rare type of head and neck cancer that affects the jawbone or surrounding tissues in the mouth. It is one of many types of oral cancers, which make up about 4% of all cancers in the United States [3].

Causes and Risk Factors

The exact cause of jaw cancer is unknown, but several risk factors have been identified:

• Age: People over 55 are more likely to develop jaw cancer.
• Sex: Men and people assigned male at birth have a higher risk.
• Tobacco use: Tobacco use is the biggest risk factor for jaw cancer [1].
• Heavy alcohol use: Associated with squamous cell jaw cancer.
• Betel nut use: Oral cancer linked to chewing the nut from the Areca palm tree.
• Obesity: Raises the risk for all head and neck cancers.
• Poor oral care: May be a contributing factor for oral cancer.
• Poor nutrition: Lack of fruits and vegetables associated with head and neck cancer.

Symptoms

The primary symptom of jaw cancer is swelling in the face, palate, or area of your jaw that supports your teeth [6]. Other symptoms may include:

• Swelling
• Pain
• Tenderness
• Unexplained tooth mobility
• A lip or mouth sore that doesn't heal
• A white or reddish patch on the gums or tongue

Treatment Options

Treatment options for jaw tumors and cysts vary, depending on the type of growth or lesion you have, the stage of growth, and your symptoms. Mouth, jaw, and face (oral and maxillofacial) surgeons can treat your jaw tumor or cyst usually by surgery, or in some cases, by medical therapy or a combination of surgery and medical therapy [10].

Other Possible Causes

Other possible causes of cancer in the jaw include:

• HPV: If your jaw cancer originated in the area of the throat behind the mouth, there’s a good chance that human papillomavirus is at work.
• Changes in cell growth: Cancer cells can keep living when healthy cells would die, causing too many cells to form a mass called a tumor [13].

Oral Cavity Cancer

Jaw cancer (cancer of the mandible and maxilla) is also known as oral cavity cancer. It can begin in the teeth or bones, including the mandible (lower jawbone) or maxilla (upper jawbone), or in the soft tissues of the mouth, such as the gums, tongue, or throat [12].

Common Signs and Symptoms of Jaw Cancer

Jaw cancer, also known as oral cavity cancer, can cause a variety of symptoms depending on the stage and location of the tumor. Here are some common signs and symptoms to look out for:

• Swelling in the face or jaw area: This is one of the most significant symptoms of jaw cancer, which can be seen on the side of the face [6][7].
• Pain or difficulty swallowing: Painful mouth sores or ulcers that don’t heal are also common symptoms of oral cancer [1][2].
• Lump or swelling in the jaw: A lump or swelling in the jaw, which may or may not be painless, is a sign of jaw cancer [10].
• White or reddish patch on the inside of the mouth: A white or reddish patch on the gums, tongue, tonsil, or lining of the mouth can also indicate oral cancer [13][14].

It's essential to note that these symptoms may not always be noticeable in the early stages of jaw cancer. However, as the tumor grows, changes become more apparent.

Other Possible Symptoms

• Fever: Fever is another possible symptom of jaw bone cancer [8].
• Oral discharge: Oral discharge can also indicate jaw bone cancer [8].

If you experience any of these symptoms, it's crucial to consult a doctor or dentist for proper evaluation and diagnosis. Early detection and treatment can significantly improve the chances of recovery.

Diagnostic Tests for Jaw Cancer

Jaw cancer, also known as oral cavity cancer, can be diagnosed using various tests and procedures. Here are some of the diagnostic tests used to diagnose jaw cancer:

• Physical Exam: A physical exam is usually the first step in diagnosing jaw cancer. Your healthcare provider will examine your gums, tongue, and neck, discuss your health history, and ask about risk factors such as smoking and tobacco use [10].
• Biopsy: A biopsy involves removing tissue samples to examine under a microscope for abnormal cells. This procedure is usually performed by an oral surgeon or a prosthodontist [1].
• Imaging Tests: Imaging tests such as CT scans, MRIs, or Panorex (a type of x-ray that shows the full upper and lower jaw) may be used to provide more details about the tissue and determine how far the cancer has spread [12, 13].

Other diagnostic tests that may be used include:

• Barium Swallow: A barium swallow test may show irregularities in the larynx, pharynx, mouth, and surrounding areas, and may often detect small, early oral tumors [4].
• Endoscopy: Endoscopy is a procedure that uses a flexible tube with a camera to visualize the inside of your mouth and throat [5].

It's worth noting that no blood test can diagnose jaw cancer, but routine blood tests may be ordered to get an idea of your overall health before treatment [1].

Treatment Options for Jaw Cancer

Jaw cancer, also known as oral cavity or oropharyngeal cancer, can be treated with various drug therapies. These treatments aim to destroy cancer cells or slow their growth.

• Targeted Therapy: Targeted drugs are designed to target specific aspects of cancer cells that fuel their growth. They can be used alone or in combination with chemotherapy or radiation therapy [1]. For example, targeted cancer drugs like cetuximab and erbitux (cetuximab) have been approved for the treatment of squamous cell mouth and oropharyngeal cancer [5].
• Chemotherapy: Chemotherapy uses anti-cancer drugs that are injected into a vein or taken by mouth to enter the bloodstream and reach most parts of the body. Chemo might be used at different times in the treatment process, such as before surgery or after radiation therapy [3]. Common chemotherapy drugs for mouth and oropharyngeal cancer include cisplatin and fluorouracil (5FU) [11].
• Palliative Care: Palliative care helps manage symptoms and side effects of cancer treatments. It can be beneficial for people with a good prognosis or those receiving hospice care [9].

Other Treatment Options

In addition to these drug therapies, other treatment options may include:

• Surgery: Surgery might be necessary to remove part of the jaw or surrounding tissue.
• Radiation Therapy: Radiation therapy uses high-energy rays to kill cancer cells. It can be used alone or in combination with chemotherapy [3].
• Immunotherapy: Immunotherapy is a rapidly developing type of cancer treatment that uses the body's immune system to fight cancer. Two immunotherapy drugs, pembrolizumab and nivolumab, have been approved for oral cancer treatment [13].

Important Considerations

When considering drug treatment for jaw cancer, it's essential to discuss the following with your doctor:

• Type of Cancer: The type of mouth or oropharyngeal cancer you have.
• Stage of Cancer: How far the cancer has grown (the stage).
• Treatment History: Any previous treatments you've had.
• Proteins in Cancer Cells: Whether your cancer has certain proteins that can be targeted by specific drugs.

Remember to ask questions and bring a recorder or friend to help with treatment decisions [1].

Differential Diagnosis of Jaw Cancer

Jaw cancer, also known as oral cancer, can be challenging to diagnose due to its similarity in symptoms with other conditions. A differential diagnosis is a process of ruling out other possible causes of the disease before confirming the actual cause.

Possible Causes of Jaw Cancer:

• Tobacco use: The most common cause of oral cancer, accounting for 70-80% of all cases [12].
• Heavy alcohol use: Associated with squamous cell jaw cancer [12].
• Betel nut use: Oral cancer linked to chewing the nut from the Areca palm tree [12].
• Obesity: Raises the risk for all head and neck cancers, including oral cancer [12].
• Poor oral care: May be a contributing factor for oral cancer [12].
• Poor nutrition: Lack of fruits and vegetables associated with head and neck cancer [12].

Other Conditions to Consider:

• Actinic Keratosis: A precancerous condition that can develop on the vermillion border of the lip [4].
• Erythroplasia: A brightly colored lesion that can be a sign of oral cancer [4].
• Melanoma: A type of skin cancer that can occur in the mouth or jaw [5].
• Sarcoma: A rare type of cancer that can develop in the soft tissues of the jaw [5].
• Lymphoma: A type of blood cancer that can affect the lymph nodes in the neck and jaw [5].

Imaging Studies:

• Radiography: Typically used to diagnose jaw lesions, including tumors and cysts [2].
• Computed Tomography (CT) scans: Can help identify the extent of the disease and guide treatment decisions [13].
• Magnetic Resonance Imaging (MRI): May be used to further evaluate the extent of the disease and plan treatment [13].

Conclusion:

A differential diagnosis of jaw cancer requires a thorough evaluation of the patient's medical history, physical examination, and imaging studies. It is essential to consider other possible causes of the disease before confirming the actual cause. Early detection and treatment can significantly improve outcomes for patients with jaw cancer.
