Introduction: Exercise is now strongly recommended for breast cancer patients to improve their overall health and quality of life. Monocytes play an important role in the cancer immune system and a better understanding of how acute exercise alters the monocyte subsets would aid in exercise prescription.
Methods: Ten breast cancer survivors (age: 59 ± 7.1) who completed their primary cancer treatment within the previous year were evaluated in this study. Using flow cytometry, monocyte subset percentages were evaluated before, immediately after, and 1 hour after 45 minutes of acute, intermittent exercise. Exercise intensity was 60% of peak wattage obtained from a cardiopulmonary exercise test.
Results: The percentage of CD14+ monocytes and CD14+CD16- monocyte subsets changed significantly across the trial (p= 0.016 and p = 0.016, respectively), with a small, non-significant increase immediately after exercise (CD14+: 9%, p= 0.314; CD14+CD16-: 5%, p= 0.594) followed by a larger significant decrease 1 hour after exercise relative to baseline (CD14+: -26%, p= 0.015; CD14+CD16-: -28%, p= 0.021). CD14+CD16+ subpopulation showed a tendency to change across the trial but this did not quite reach significance (p= 0.097).
Conclusion: These findings suggest that acute intermittent exercise mobilizes CD14+ monocytes and CD14+CD16- monocyte subsets in breast cancer survivors in a manner that is comparable to previous reports in healthy individuals. Further studies are warranted to determine the functionality of the mobilized monocytes and the effects of exercise training.
