KEYTRUDA for head and neck cancer 


About head and neck cancer

If you have been diagnosed with head or neck cancer, or you know somebody who has, you’re probably looking for reliable information about the disease and its treatments. This section will help to answer many of your questions.

Types of head and neck cancer

How head and neck cancers are named depends on where the cancer first starts. Cancer can also start in the brain, eye, oesophagus, thyroid gland, skin, scalp or the bones or muscles of the head and neck, however these cancers are not known as head and neck cancers. The following are types of head and neck cancers.

  • Oral cancer describes cancer that affects your lips, gums, cheek lining, floor of your mouth, roof of the mouth (hard palate), your tongue or the muscles on the base of your tongue that extend down into your throat.
  • Nasopharyngeal cancer refers to cancer in the upper region of the throat behind the nose, but before your mouth joins the throat.
  • Oropharyngeal cancer is cancer that begins in the middle region of the throat, roughly behind your mouth.
  • Hypopharyngeal cancer describes cancer in the lower region of your throat, behind your voice box (larynx).
  • Laryngeal cancer means cancer that affects your voice box (larynx).
  • Salivary gland cancer affects any or all of your salivary glands – there are three large salivary glands and hundreds of smaller ones.
  • Nasal cancer begins in any of the cells lining the large, hollow space (nasal cavity) inside the nose that warms, moistens and filters the air you breathe.
  • Paranasal sinus cancer affects any or all of the small, air-filled spaces (paranasal sinuses) that surround the nasal cavity.
  • Metastatic head and neck cancer refers to cancer that has spread from where it started to another part of your body.
  • Recurrent head and neck cancer means cancer that has come back after previous treatment.

Incidence of head and neck cancer

Head and neck cancer represents the sixth leading cancer by incidence worldwide. Nearly all the cases of head and neck malignancies (95%) are represented by squamous cell carcinoma arising in the oral cavity and pharynx.

What are the symptoms?

  • Pain in the area
  • Swelling in the area
  • A hoarse voice
  • Difficulty swallowing
  • Bad breath

How is it diagnosed?

If your doctor suspects head or neck cancer, these tests may be required:

  • Physical examination
    Diagnosis usually begins with an examination of your mouth, throat, nose, neck, ears and eyes.
  • Nasendoscopy
    A nasendoscope is an examination device that allows closer inspection of the nose and throat area. It involves a thin flexible tube with a light and camera on the end that is passed through your nostril.
  • Biopsy
    The nasendoscope can be used to take a tissue sample (biopsy) of unusual looking areas.
  • Laryngoscopy
    A laryngoscope is a device that allows your doctor to look at your larynx and pharynx, then take a biopsy if necessary. In this procedure, a tube with a light and camera on it is inserted into your mouth and throat.
  • Imaging tests
    An X-ray scan, CT scan, MRI scan, PET scan or ultrasound may be required as part of the diagnostic process.

Treatment for head and neck cancer

  • Tumour surgery
    Surgery aims to remove cancerous tissue in a way that preserves the functions of your head and neck, such as breathing, swallowing and talking. Surgical procedures and recovery times will differ depending on the location and extent of your cancer.
  • Lymph node removal
    Depending on the extent of your cancer, your surgeon may remove some lymph nodes. This operation is called a lymphadenectomy. There is a possibility it will affect the movement and appearance of your neck or shoulder.
  • Radiotherapy
    Also known as radiation therapy, radiotherapy is used to kill or harm cancer cells. It is carefully targeted to do as little harm as possible to healthy tissue.
  • Chemotherapy
    Chemotherapy involves the use of drugs to kill or slow the growth of cancer cells in the body. It is usually given by injection into a vein (intravenously) at treatment sessions over several weeks. Chemotherapy affects all rapidly dividing cells, so there can be uncomfortable side effects.
  • Targeted therapies
    Targeted therapies are newer treatments that attack specific molecules within cells to help prevent cell growth. Compared to chemotherapy, they have fewer side effects.
  • Immuno-oncology treatment
    KEYTRUDA is an immuno-oncology treatment for advanced and reoccurring head and neck cancer. It may be used when platinum and cetuximab-based* therapies didn’t work, or are no longer working.

*Cetuximab is not funded in New Zealand
