Mesothelioma Cancer Treatment

Mesothelioma Cancer Treatment

Conventionally, the more advanced stages of mesothelioma cancer are treated with either radiation therapy or chemotherapy. Radiation therapy utilizes high-energy x-rays to destroy cancerous cells and shrink tumours Chemotherapy, on the other hand, uses drugs to destroy cancer cells. The aim of these mesothelioma cancer treatments is to prolong the patient’s life as the disease cannot be cured in the more advanced stages.

In addition to these conventional mesothelioma cancer treatments, there are also various experimental treatments currently under investigation which offer new hope.

Immunotherapy: This form of biological therapy for mesothelioma cancer treatment uses the patient’s own immune system to attack the cancerous cells. Clinical studies have shown that the immune system is able to distinguish healthy cells from cancer cells, and can therefore be used to destroy those cancerous cells.

Gene Therapy: This form of mesothelioma cancer treatment is very much still in the developmental stages. The process involves injecting a specific gene straight into the tumour. This gene renders the cancer cells sensitive to the antiviral drug glanciclovir which under normal circumstances is not effective against these cells. The glanciclovir is then able to destroy all the cancer cells without harming the healthy tissue cells.

Drug Therapy: The drug Alimta is the only chemotherapy drug to be approved by the Food and Drug Administration (FDA)for the treatment of patients with malignant mesothelioma lung cancer . This new and exciting drug has been demonstrated in clinical trials to reduce symptoms and increase the life expectancy of patients.

Photodynamic Therapy: Photodynamic therapy involves the use of light to destroy cancer cells. The patient first is first administered a photosensitizing drug that only collects in cancerous cells. Fibre-optic cables are then inserted in the body in order to focus light of a certain frequency on the tumour. The light stimulates the photosensitizing drug to produce toxic oxygen molecules that destroy the cancerous cells.

These experimental mesothelioma cancer treatments, although still in the developmental stages, offer cancer victims the prospect of a better and longer life. With the likelihood of an increase in the number of people diagnosed with asbestos cancer, further research into other forms of mesothelioma cancer treatment is vital.
