Exercise to Boost Immunity in Advanced Cancer

The trial is a prospective feasibility trial conducted in Sheffield. Recruitment will include twenty patients receiving first line palliative immunotherapy for advanced, unresectable or metastatic mesothelioma and patients receiving first line systemic anti-cancer treatment for pancreatic cancer. Patients will attend the AWRC for a supervised exercise session once a week to include aerobic exercise along with an unsupervised weekly exercise session for 3 months. Blood samples will be collected at baseline and then monthly for 3 months, pre and post the supervised exercise session. Cytokine, myokine and immune cell concentration will be analysed using cytokine bead-based multiplex immune assays and RNA-seq to full profile changes in gene and protein expression

Immunotherapy is rapidly revolutionising cancer care with ICIs demonstrating clinical efficacy in multiple cancer settings and are indicated in the peri-operative, advanced, and recurrent settings for various tumour types. Mesothelioma is classed as a "hot tumour" due to its lymphocyte rich tumour microenvironment which has demonstrated some clinical response to immunotherapy. On the other end of the spectrum, 'cold tumours' such as pancreatic cancer, have been shown to have low immune cell populations and reduced immune activity within their tumour microenvironments. Evidence suggests that in cancer patients, exercise improves overall health, may prolong survival as well as reduce cancer-related fatigue and modulate the immune system through multiple mechanisms. Physical activity is defined as 'any bodily movement produced by skeletal muscles or that requires contraction of your muscles and energy expenditure. Exercise-induced leucocytosis refers to the immediate increase in circulatory leukocytes after a single exercise activity. The use of exercise as medicine requires an understanding of the appropriate dose which is highly dependent on the FITT principles (Frequency, Intensity, Time, and Type) and this is crucial for generating desired outcomes. Although ICIs have revolutionised treatment for many different cancers, less than 40% of patients derive significant benefit from ICIs which highlights the need to improve responsiveness The primary objective is to determine the feasibility of exercise during systemic anti-cancer treatment in patients with advanced mesothelioma or pancreatic cancer. The secondary objectives are: iTo determine the safety of exercise during systemic anti-cancer treatment in patients with advanced mesothelioma or pancreatic cancer. ii. To determine the acceptability of exercise during systemic anti-cancer treatment in patients with advanced mesothelioma or pancreatic cancer. iii. Does exercise boost immune cell activation in cancer patients? iv. To determine the effect of exercise on cytokine/ myokine levels in the blood v.To determine the effect of exercise on radiological response or progression. vi.To determine the effect of exercise on lung function.
