Clinical Scorecard: Impact of Various Exercise Modalities on Depression and Anxiety Among Cancer Survivors: A Systematic Review and Bayesian Network Meta-Analysis of Randomized Controlled Trials

At a Glance

Key Highlights

• Exercise interventions produce small-to-moderate improvements in depression and anxiety compared to non-exercise controls.
• Mind-body exercises (Tai Chi and Qi gong) and aerobic exercise show consistent benefits with larger evidence bases.
• Recommended exercise prescriptions: for depression ~2.8 METs, 40 minutes/session, six sessions/week; for anxiety moderate intensity and duration, five sessions/week, both lasting ~20 weeks.

Guideline-Based Recommendations

Diagnosis

• Routine screening for anxiety and depression in patients with cancer is recommended.

Management

• Consider mind-body exercises such as Tai Chi and Qi gong as first-line exercise interventions due to stable evidence.
• Aerobic exercise is also recommended for consistent benefits.
• Pilates and high-intensity interval training (HIIT) show promising effects but require cautious interpretation due to low certainty evidence.
• Exercise prescriptions should be individualized rather than fixed.

Monitoring & Follow-up

• Monitor adherence and intervention fidelity to ensure robustness of effect estimates.
• Observe for plateauing of benefits around 20 weeks without additional gains at follow-up.

Risks

• Higher BMI and older age may attenuate exercise benefits on depression and anxiety.
• No significant association found between female proportion and treatment effect.

Patient & Prescribing Data

Cancer survivors with depression and/or anxiety symptoms

Optimal dose for depression: ~2.8 METs, 40 minutes per session, six sessions per week; for anxiety: moderate intensity and duration, five sessions per week; treatment duration approximately 20 weeks; effects plateau thereafter.

Clinical Best Practices

• Prioritize mind-body exercises (Tai Chi, Qi gong) and aerobic exercise for psychological symptom management in cancer survivors.
• Individualize exercise prescriptions considering patient age, BMI, and preferences.
• Incorporate routine psychological screening and integrate exercise as part of multidisciplinary survivorship care.
• Ensure adequate reporting and monitoring of exercise adherence and fidelity in clinical practice.
