Exercise after lung cancer diagnosis linked to better outcomes

A new study adds to growing evidence that physical activity may have an important place in lung cancer care.

Published in JAMA Network Open, the paper analysed data from 17,141 cancer survivors across 6 pooled cohort studies. It looked at moderate to vigorous physical activity before and after diagnosis and asked whether activity after diagnosis was associated with cancer mortality. The analysis included people with bladder, endometrial, kidney, lung, oral, ovarian and rectal cancers.

For lung cancer, the findings were notable. Compared with doing no moderate to vigorous physical activity after diagnosis, even lower levels of activity were linked with lower cancer mortality. In the paper’s main results, low levels of activity after diagnosis were associated with a hazard ratio of 0.56 compared with none.

One of the most interesting parts of the study was that this was not only seen in people who had already been active before diagnosis. Among lung cancer survivors who were inactive before diagnosis but met activity guidelines after diagnosis, cancer mortality was also lower, with a hazard ratio of 0.58.

This suggests that becoming active after diagnosis may still be linked with benefit, even for people who were not active before. The paper’s key points say that lung cancer survivors who were inactive before diagnosis but became active afterwards had lower risk of cancer mortality.

The authors also make clear that this was an observational pooled analysis, not a clinical trial. That means it shows an association rather than proving that exercise directly caused the survival difference. Still, the findings add weight to the case for physical activity and exercise support to be taken seriously as part of cancer care, where safe and appropriate for the individual.

The paper also notes that current physical activity recommendations for people with cancer are stronger for some cancer types than others, and that evidence for cancers such as lung cancer has been more limited.

For many people living with lung cancer, movement is not straightforward. Fatigue, breathlessness, pain, treatment side effects, anxiety and reduced fitness can all get in the way. Research like this does not mean people should feel pressured to do more than is safe or manageable. But it does support a wider conversation about how exercise, rehabilitation and personalised physical activity support could fit more clearly into lung cancer care.
