Mesothelioma

Name of disease:

Mesothelioma

ICD-10 diagnosis code:

C45

Causes:

  • Mesothelioma is almost always caused by exposure to asbestos. The tiny fibres of asbestos can easily get into the lungs where they get stuck damaging the lungs over time.
  • It usually takes a while for this to cause any obvious problems with mesothelioma typically developing more than 20 years after exposure to asbestos.
  • The import, transhipment, supply and use of all forms of asbestos and materials containing asbestos has been banned in Hong Kong since 2014.

Mode of inheritance:

Mesothelioma is not hereditary. Nonetheless, research suggests genetic risk factors such as a mutated BAP1 gene increase the likelihood an individual will develop mesothelioma as a result of asbestos exposure.

Prevalence:

According to the Hospital Authority of Hong Kong, there were 455 new cases of mesothelioma and 349 deaths from this disease between 2001 and 2020.

Diagnosis:

A number of different tests may need to be carried out, including:
  • An X-ray of chest or abdomen
  • A CT scan
  • Fluid drainage
  • A thoracoscopy or laparoscopy

Age of onset:

40 - 70 years old

Common signs and symptoms:

  • Symptoms of mesothelioma in the lining of the lungs include:
    • Chest pain
    • Shortness of breath
    • Fatigue
    • A high temperature and sweating particularly at night
    • A persistent cough
    • Loss of appetite and unexplained weight loss
    • Clubbed fingertips
  • Symptoms of mesothelioma in the lining of the stomach include:
    • Stomach pain or swelling
    • Feeling or being sick
    • Loss of appetite and unexplained weight loss
    • Diarrhoea or constipation

Available treatment (medicinal and non-medicinal):

  • Chemotherapy – using medicine to help shrink the cancer
  • Radiotherapy – using high-energy radiation to kill cancer cells or slow the cancer down and keep it under control
  • Surgery – removing the cancerous area if the mesothelioma is detected at a very early stage
  • Immunotherapy – using a combination of two medicines to help stimulate the immune system to attack cancer cells. Immunotherapy cannot cure mesothelioma but it can slow the spread of the disease and prolong the lifespan.
  • Tumour treating fields (TTFields) – administered by a portable electronic device. This passes gentle electric fields through the patient’s skin to slow cancer cell growth and help prolong patient survival.

Disease management tips:

Research shows that self-care is often helpful for managing life after a cancer diagnosis like mesothelioma. For a mesothelioma patient or survivor, self-care can help relieve negative emotions they may feel. It may also support mental health and improve quality of life.
  • Call a friend or loved one to catch up: Conversations can help you stay connected to the people you care about
  • Express your creativity such as in painting, drawing, writing, or anything else that sounds fun
  • Have a cup of tea with a favourite snack
  • Listen to supportive podcasts
  • Practice mindful activities such as gentle yoga, breathwork, or meditation
