It’s taken for granted that rehabilitation is part of the recovery process for many medical conditions, yet pulmonary rehabilitation for people with lung cancer is less commonly prescribed. The reason is not a lack of efficacy – rehab can make a significant difference for some people with lung cancer. We don’t have as much information about it’s role with lung cancer, but pulmonary rehabilitation for people with COPD has recently become recognized as an essential part of a COPD treatment plan. When can pulmonary rehab help, and what should you know when you talk to your doctor?

What is Pulmonary Rehabilitation?

Pulmonary rehabilitation is a coordinated approach to improving quality of life that uses the expertise of several specialties. Some of these include respiratory therapists, physical therapists, occupational therapists, nutritionists, psychologists, exercise physiologists, and more. Even though "breathing easier" might be one goal of rehab, we know that many factors work together to improve or impede quality of life in people with cancer.

Pulmonary rehabilitation is different than chest physical therapy (also called chest physiotherapy.) Chest physical therapy involves techniques used to remove excess mucous from the lungs.

What Happens During Pulmonary Rehabilitation?

There are several components to pulmonary rehab. A mainstay of this treatment is education. This may include information about your cancer, nutritional information, breathing techniques, and methods for coping with the stress of a cancer diagnosis. Sessions with a pulmonary rehab specialist may include:
  • A walk test. Before beginning rehab a therapist will often check your baseline lung function tests. She may also do something called a 6 minute walk test - which will look at the distance you can walk on a firm surface for 6 minutes comfortably.

  • Instruction in breathing techniques. For example, the technique known as diaphragmatic breathing to strengthen the diaphragm and decrease the fatigue of breathing, and pursed-lip breathing to help decrease the sensation of shortness of breath.

  • Energy conserving techniques. This may include ways to be more active with less shortness of breath. For example, you may be instructed on Tips for Avoiding Shortness of Breath With Eating.

  • Instruction in the use of medications to help breathing – Such as How to Use Inhalers Properly.

  • Aerobic exercise – Such as walking on a treadmill or using an exercise bike to improve endurance and increase lung capacity.

  • Weight lifting – To build strength in breathing muscles.

  • Training respiratory muscles to assist respiration.

  • Relaxation techniques and coping strategies.

  • Nutrition counseling.

  • Psychological support – Psychologists may help you understand how emotions and psychological stress can affect your breathing.

How Does it Help People With Lung Cancer?

Though it hasn’t been studied as extensively for lung cancer as it has for COPD, studies have found that pulmonary rehabilitation (in the right situations and at the right time during treatment) may:
  • Improve the ability to exercise and do day to day activities.

  • Lessen complications of lung cancer surgery (see below.)

  • Improve pulmonary function.

  • Improve quality of life.

  • Improve co-existing medical conditions. It’s not uncommon for people with lung cancer to also have emphysema and COPD. Studies have found that in these patients, pulmonary rehab results in less shortness of breath, better exercise performance, and better health-related quality of life.

Pulmonary Rehabilitation Before Lung Cancer Surgery

Research is just beginning that looks into the role of pre-operative pulmonary rehab on surgery outcomes. What we are learning so far is that rehab may:
  • Decrease complications following surgery.

  • Improve breathing so that potentially curative lung cancer surgery can be done.

  • Possibly improve outcomes after lung cancer surgery.

  • A few small studies found that people who had rehab before surgery had shorter hospital stays, less morbidity (that means sickness) near the time of surgery, and had a shorter duration of needing a chest tube following surgery.

When Should Pulmonary Rehabilitation Be Started?

Your oncologist, thoracic surgeon, or pulmonologist will need to work with you to determine the best time for pulmonary rehabilitation. One study found that rehab shortly after thoracotomy resulted in increased pain, and suggested that it might be better to wait 3 or 4 months after major chest surgery to begin rehab.

What About People With Inoperative Lung Cancer?

Even people with advanced lung cancer may benefit from pulmonary rehab. In addition, many people with stage 4 disease do not have surgery, and therefore may be able to begin a rehab program right away without waiting for surgical incisions to heal.

How to Get Started

The best place to start is by talking to your lung cancer doctors to learn about pulmonary rehabilitation programs in your area. Many of the larger cancer centers offer these services on an outpatient as well as inpatient basis. If your physicians are not aware of programs, you can check:

Risks

Risks associated with pulmonary rehabilitation are primarily the risks inherent with any exercise program. If someone has unstable heart disease, exercise can increase the risk of arrhythmias or heart attacks. For people with osteoporosis, the risk of bone injury is greater. For those on chemotherapy, the risk of infection when in contact with others should be considered. For people who have had surgery it’s important that the surgical site is well healed to avoid the risk of a surgical incision opening.

Does Insurance Cover This Treatment?

It’s important to check with your insurance provider to see what will be covered by your particular plan. If treatment is not covered, you may want to consider entering one of the clinical trials that are studying the benefit of pulmonary rehab for people with lung cancer. If you aren’t sure where to start, there is a Lung Cancer Clinical Trial Matching Service, that provides free help in searching clinical trials available worldwide.

Why Haven’t I Heard About Pulmonary Rehab for Lung Cancer?

Talking with lung cancer survivors I’m aware that many people have never heard about pulmonary rehab. Part of the reason is a lack of awareness about these services – even by physicians. Research has also cited long waiting lists as one reason. A major reason is that the benefits of rehabilitation for people with lung cancer is just beginning to be studied as it has been for other conditions such as COPD.
