Encouraging improvements in Treating Lung Cancer

Lung cancer is the biggest killer
in Hong Kong. More than 80 percent of
cases are caused by what is known as
non-small cell carcinoma (NSCLC). But
encouraging advances have been made in
recent years in the treatment of NSCLC.

The current standard way of dealing
with early-stage NSCLC is to resects completely
the part of the organ affected by it. However,
the 5 year survival rate is still less than
satisfactory.

In the past decade, cisplatin-based
chemotherapy had been used on patients
following resection. Their survival rate
is more favorable, and the side effects
from this king of chemotherapy were more
tolerable.

Adjuvant chemotherapy, or additional
chemotherapy, can be considered as part of
standard treatment for younger patients in
early disease stage who have responded well
to resection.

The standard first-line treatment for recurring
or advanced lung cancer is a treatment that uses
a combination of chemotherapy and radiotherapy
for patients in relatively better conditions,
using a combination of platinum and a newer
chemotherapy agent (e.g paclitaxel, docetaxel
or gemcitabine) can further improve their
survival rate.

The treatment of the future for lung cancer
will probably involve the development of novel
molecularly targeted therapies and their
application together with chemotherapy.

Using Bevacizumab, a drug which targets
the angiogenesis in tumors, in conjunction
with chemotherapy have shown very good results,
but this treatment also increases the risk of
haemoptysis, the coughing of blood, which is
life-threatening.

Encouraging improvements have been made
in treating lung cancer in recent years. providing
more options for patients to deal with the
deadly disease, This augurs well for lung
cancer victims who may see some notable
breakthroughs in the near future.

Lung Disease with No Cure

Chronic Obstructive Pulmonary Disease (COPD) is a common and incurable lung disease that can kill. Because there are no specific symptoms at the early stages of the disease, the victim is often under diagnosed.

COPD symptoms include coughing, discharge of sputum, and shortness of breath (especially during exercise). The sufferer’s lung function deteriorates over time and he or she will find breathing increasingly difficult.

Smoking is a major cause of COPD. The best way to prevent it is not to smoke. Exposure to passive smoking is also a contributing factor. Quitting smoking can slow down the disease’s progression. Other causes of COPD include exposure to occupational dusts, chemicals, and dirty air.

Spirometry (a method of gauging lung function) is used to diagnose COPD. Treatment strategy should be used according to the patient’s needs, based on the symptoms he or she is experiencing and on the findings of the test.

Objectives of the treatment are to reduce the effect of the symptoms, slow the spread of the disease, improve exercise tolerance and quality of life to an extent.

The most common medications for COPD are inhalational bronchodilators and glucocorticosteriods. Influenza vaccine and pneumococcal polysaccharide vaccine can also help reduce the risk of complications occurring. In addition to medication, longterm oxygen therapy can further reduce the discomfort suffered by patients with chronic respiratory disorder.

COPD patients should follow rehabilitation programmes, drawn up and supervised by healthcare professionals to help them go about their daily lives more comfortably.
