Will a Pre-therapy Exercise Intervention Improve the Outcomes of Patients With Advanced Oesophageal Cancer?

Background Regular exercise can significantly improve physical and mental health during cancer treatment and reduce the time needed in the hospital. Animal studies suggest that exercise training can also reduce the number of cancer cells. For example, exercise training in mice produces more immune cells in the tumour. These immune cells in the tumour contribute to the destruction and reduction of the size of the tumour and are a vital component of effective immunotherapy (cancer treatment that helps the immune system fight cancer). In humans, exercise training and the immune response in tumours are less understood. Only 1 study has investigated the effect of a single exercise session before surgical removal of the prostate in prostate cancer patients. As the benefits of exercise are gained from weeks/months of exercise, no effect on the immune cells in the tumours were found. The investigators have carried out a previous study looking at how exercise affects fitness before major surgery. After this they used state-of-the-art methods to detect and visualise immune cells within the tumour. Compared with the patients who did not exercise, the exercise group had significantly more immune cells in their tumours, consisting of a group of cells that are important for killing cancerous cells called CD8+ T cells. CD8+ T cells in tumours are associated with improved survival outcomes. Importantly, they found a link between changes in fitness and the amount of these cells in the tum…
