Postdiagnosis Physical Activity Linked to Improved Physical QoL in Prostate Cancer Survivors

Why exercise improves prostate cancer outcomes

Prostate cancer survivors who maintain or begin recreational physical activity following cancer diagnosis report substantially higher quality of life than those who never exercise or stopped exercising after diagnosis, according to a study published in the journal Cancer Epidemiology, Biomarkers & Prevention.1

For the case-control study, investigators evaluated associations between post-diagnosis physical activity and change from pre-diagnosis physical activity with quality of life in 830 survivors of invasive prostate cancer. Quality of life was measured using the 36-item short survey instrument (SF-36).

Results showed that both total and recreational physical activities were associated with improved physical quality of life. In addition, researchers found that men who continued to meet physical activity guidelines from prediagnosis through postdiagnosis reported significantly higher physical and mental quality of life scores compared with patients who did not perform the recommended levels of exercise.

The study further demonstrated that patients who began performing the recommended amount of exercise after diagnosis had improved quality of life, while patients who could not maintained the recommended levels experienced decreased quality of life.

The findings ultimately suggest that recreational physical activity after diagnosis is associated with improved physical quality of life. Future studies should evaluate how achieving and maintaining adherence to physical activity guidelines postdiagnosis impacts outcomes of prostate cancer survivors.
