What is Salivary Gland Cancer ?

Salivary gland cancer is an uncommon cancer originating in the salivary glands of the mouth, which produce saliva. Saliva plays an important role in digestion, lubrication of food, maintenance of oral health, and protection of the mouth and teeth from infection.

There are three major sets of salivary glands, and there are hundreds of smaller salivary glands located throughout the mouth and throat. Among the main salivary glands are the parotid glands, which are located at the front of the ears, the submandibular glands, which are located at the bottom of the jaw, and the sublingual glands, which are located at the bottom of the tongue. The parotid glands are the most common site for cancer development, yet cancer can arise from any gland.

Salivary gland tumors may either be benign (noncancerous) or malignant (cancerous). Malignant tumors need immediate diagnosis and specific medical care because they have the ability to spread to nearby areas and other body regions, even though benign tumors occur more frequently.

Salivary gland cancer is a form of head and neck cancer that can affect anyone of any age, but it is common in adults. The chances of treating the disease successfully lie in early diagnosis and subsequent treatment.

The treatment options for salivary gland cancer are determined by multiple factors that include the tumor type, its location and size, and whether it has metastasized. The main treatment approach consists of surgical procedures combined with radiation treatment and, in some cases, chemotherapy or targeted therapy.

Patients will achieve better treatment outcomes when they understand the symptoms and causes, diagnostic procedures, and treatment methods, as this knowledge enables them to seek timely medical care.

What are the Symptoms & Causes of Salivary Gland Cancer ?

Symptoms of Salivary Gland Cancer

The symptoms of salivary gland cancer generally vary depending on the gland involved and the size of the tumor, and the initial noticeable symptom is a painless lump that appears near the jaw, ear, or mouth.

Common symptoms may include:

• A lump or swelling near the jaw or ear area: Medical professionals consider a lump near the ear and jawline, cheek, and neck to be one of the most common signs of salivary gland cancer. The lump may develop slowly over time, and people may experience pain or not.
• Facial weakness or numbness: The tumor can affect nearby nerves, including the facial nerve, resulting in three effects: facial muscle weakness leading to difficulty with facial movements, and numbness and tingling in the face.
• Pain in the face or mouth: The affected area produces ongoing pain for some patients because the tumor presses on nearby tissues and nerve pathways.
• Difficulty swallowing: A tumor in the mouth or throat region usually causes difficulty swallowing food or a sensation of something stuck in the throat.
• Difficulty opening the mouth: Some tumors can limit jaw movement, preventing people from fully opening their mouths.

Other possible symptoms

Additional symptoms may include:

• Changes in speech
• Persistent swelling in the neck
• Ear pain without infection
• Fluid drainage from the ear
• Unexplained weight loss

The symptoms can also appear with other noncancerous health issues. A medical evaluation is necessary when symptoms persist for an extended period.

Causes of the Salivary Glands

Genetic changes in the DNA of salivary gland cells lead to cancer by causing them to grow and multiply rapidly. These abnormal cells develop into masses of tissue known as tumors.

Healthy cells follow a systematized pattern of growth and division. When genetic alterations disrupt this process, cells begin to multiply abnormally, leading to the formation of cancerous growths.

The precise reasons behind the genetic mutations remain unidentified in most cases.

What are the Risk Factors for Salivary Gland Cancer ?

The reasons why people develop salivary gland cancer remain unknown, yet multiple risk factors exist that elevate the likelihood of developing this condition.

• Older age: Salivary gland cancer occurs more frequently in older adults, yet it can develop at any age.
• Radiation exposure: People who received radiation therapy in the head and neck region face an increased chance of developing salivary gland cancer in their later years.
• Occupational exposure: Workers in rubber manufacturing, plumbing, and mining face higher cancer risks because they handle dangerous substances.
• Tobacco use: Smoking and tobacco use are associated with several head and neck cancers and may contribute to the development of salivary gland tumors.
• Family history: A family history of specific cancers can lead to increased cancer vulnerability, although this situation occurs only in rare instances.

Salivary gland cancer has different types, which originate from multiple malignant tumors. The different types of cancer exhibit distinct growth patterns and levels of aggressiveness, which require different treatment methods. The most frequently occurring types include:

• Adenoid cystic carcinoma: The cancer demonstrates slow growth patterns yet shows potential for nerve invasion and post-treatment recurrence.
• Acinic cell carcinoma: The parotid gland serves as the primary site for this type of cancer, which typically progresses at a gradual pace.
• Adenocarcinoma: Adenocarcinoma arises from glandular cells that can occur in various salivary glands.
• Salivary duct carcinoma: This salivary gland cancer form exhibits higher aggression than other types and demands extensive medical care.
• Mucoepidermoid carcinoma: The most commonly prevailing salivary gland cancer is this specific cancer type. The disease presents as low-grade tumors that develop slowly or high-grade tumors that grow more rapidly.

How is Salivary Gland Cancer Diagnosed & Tested ?

Early detection of salivary gland cancer is crucial for achieving effective treatment.

The physician starts the diagnostic process by conducting a medical history assessment and performing a physical examination to detect any irregularities.

• Physical Examination: The physician conducts an exhaustive physical examination of the face, jaws, neck, and mouth to assess for swellings and facial paralysis, which may suggest a nerve problem.
• Imaging tests: Imaging tests enable medical professionals to identify the tumor's dimensions and position, as well as its potential to spread to other parts of the body.
• Ultrasound: Neck and salivary gland lumps are evaluated by ultrasound, which determines whether the mass is solid or fluid-filled.
• Magnetic Resonance Imaging (MRI): The MRI system produces detailed soft-tissue images that doctors use to assess whether tumors have invaded adjacent nerves or structures.
• Computed Tomography (CT) scan: The CT scan produces detailed images which assist physicians in determining tumor dimensions and identifying its extension to adjacent body parts and lymphatic nodes.
• PET scan: A PET scan determines whether cancer has spread to distant regions of the body.
• Biopsy: The medical diagnosis of salivary gland cancer requires a biopsy test to establish the diagnosis.

The biopsy process involves removing a small tissue specimen from the tumor area for microscopic analysis. The biopsy procedure identifies the cancer type while assessing its level of aggressiveness.

Fine-needle aspiration biopsy is the primary diagnostic method for salivary gland tumors.

Additional tests

The medical team conducts additional tests to assess the current stage of the patient's cancer.

The process consists of these tests:

• Blood tests
• Lymph node imaging
• Chest imaging to check for spread to the lungs

The medical team uses staging to develop treatment plans that identify the most effective management methods.

What Treatment options exist to treat Salivary Gland Cancer ?

The medical team selects treatment methods for salivary gland cancer based on various factors, which include cancer type and location, disease stage, and patient health status.

The healthcare team provides comprehensive medical services through a multidisciplinary approach.

Surgery

Surgery represents the primary treatment method for patients with salivary gland cancer.

The surgical procedure aims to excise the tumor together with surrounding healthy tissue to decrease the probability of cancer recurrence.

Surgical procedures may include:

• The surgical procedure involves removing the affected salivary gland.
• The surgical procedure involves removing the surrounding tissues when the tumor has spread.
• The surgical procedure contemplates the selective removal of neck lymph nodes, as needed.

Surgical reconstruction serves as a necessary solution in specific instances to restore both functional abilities and physical appearance.

Radiation therapy

Radiation therapy employs high-energy radiation to eliminate cancerous tumor cells.

The procedure receives post-surgical recommendations to remove remnants of cancer cells and lessen the possibilities of cancer recurrence.

Radiation therapy serves as an alternative treatment option when surgical interventions remain unfeasible.

Chemotherapy

Chemotherapy treatment utilizes anti-cancer medications to destroy cancerous cells or prevent their reproductive process.

Chemotherapy becomes necessary for advanced cases of salivary gland cancer, which have spread to other areas of the body.

Targeted therapy

Targeted therapy focuses on specific molecular alterations in cancer cells. The treatment methods prevent tumor growth while focusing on protecting healthy cells from harm.

Certain cases of advanced or recurrent salivary gland cancer may require follow-up targeted treatments.

Supportive care

Patients who receive treatment face various side effects, which include tiredness, pain, and problems with their ability to consume food.

Supportive care includes the following treatment options:

• Pain management
• Nutritional support
• Speech and swallowing therapy
• Psychological support

The treatment program implements these services to enhance the patient's treatment experience.

What factors influence the prognosis and survival rates for Salivary Gland Cancer?

The prognosis for salivary gland cancer is based on many factors, such as tumor type, tumor stage, and how patients respond to treatment. Early-stage tumors detected and treated early are likely to yield better outcomes. The factors that influence prognosis evaluation include:

• The size and position of the tumor
• The tumor is moderately severe.
• The cancer has progressed to nearby lymph nodes or distant body parts.
• The patient's complete medical condition assessment

The combination of improved surgical methods and current cancer treatment options enables most salivary gland cancer patients to achieve successful treatment results.

Follow-up care

In this phase, patients must continue their follow-up treatment schedule. Through these follow-ups, physicians can monitor recovery progress, detect relapses, and address the residual effects of treatment. During these checkups, physicians examine their patients physically and run tests.
