Pulmonary Rehabilitation in Advanced Lung Cancer Survivors

Description

Lung cancer (LC) is the second most common cancer in the world, (1) and the third most common cancer in the United States of America (USA) (2). Because more lung cancer screenings are being done (3-5) and because there have been advances in treatments, people will all stages of LC are living longer, including those with advanced LC. Research has shown that fatigue and breathing issues are commonly experienced by LCS (6). These symptoms can hurt the long-term health and quality of life of LCS (6-8). Currently, there are not many interventions that are used to help these symptoms for LCS.

For people with non-cancer-related respiratory disease, like chronic obstructive pulmonary disease (COPD), a type of supportive treatment called pulmonary rehabilitation (PR) can improve symptoms like difficulty breathing, fatigue, difficulty exercising, and health-related quality of life (9-11). PR is a holistic treatment plan that includes a full assessment and is then personalized to fit each person’s needs. This could include things like exercise training, education, and behavior change (12). PR is considered standard-of-care for people with COPD (13). PR includes physical activity, which is something that is encouraged in all cancer survivors.

There is not much research that talks about the barriers to physical activity in survivors of lung cancer, although fatigue may be one of the most significant ones (14). Doctors may also not feel comfortable encouraging physical activities in people with lung cancer due to concerns about the safety and feasibility in exercise in people with lung cancer (15). However, PR is safe and effective in people with chronic pulmonary conditions, with well-established pathways and programs for these people.

As stated above, LCS have persistent fatigue and difficulty breathing, which is often worse in people who have metastatic LC. There is limited, high-quality evidence supporting interventions designed specifically for LCS with advanced disease. PR is potentially a safe and available intervention to improve functional status in LCS with early stage disease, and more research is needed to understand its impact on LCS with metastatic NSCLC treated with modern therapies.
