In a SEER-Medicare analysis of 265,639 adults aged 66 and older with common cancers, pre-existing depression was associated with an 11% higher risk of cancer-specific mortality, while psychotherapy started within 4 weeks of diagnosis was associated with a 21% lower mortality risk. The findings, presented at the 2026 ASTRO Annual Meeting, suggest that early depression recognition and referral may meaningfully influence cancer outcomes in frontline practice.

Why It Matters To Your Practice

• NPs and PAs are often the clinicians most likely to spot depression early, especially when fatigue, poor concentration, and loss of interest can be mistaken for cancer symptoms or treatment effects.

• In this study, 22% of older adults with cancer had pre-existing depression, yet most received neither psychotherapy nor antidepressants within 8 weeks of diagnosis.

• Your assessment and referral are not “extra” to oncology care — they may be a pivotal part of comprehensive cancer management.

Clinical Benefits

• Patients with depression had worse cancer-specific mortality: 29% vs 21% at 1 year, and 43% vs 35% at 5 years.

• Psychotherapy within 4 weeks was associated with a 21% lower risk of cancer-specific mortality.

• The benefit signal weakened with delay: psychotherapy started by 8 weeks was associated with a 13% lower mortality risk, and by 12 weeks with a 12% lower risk.

• Five-year cancer-specific mortality was 31% among patients who received psychotherapy vs 44% among those who did not.

Managing Risks

• This was an observational study presented at ASTRO, so it shows association, not proof of causation.

• Antidepressant use was more common than psychotherapy, with 32.5% receiving medication within 4 weeks, but it was not associated with lower cancer-specific mortality at measured timepoints.

• Use caution not to overinterpret: treatment choice should still reflect cancer type, prognosis, symptom burden, access, and patient preference.

• Practical move: build depression screening and fast referral pathways into new cancer visits, especially for older adults.

The Bottom Line

• For older adults with cancer and depression, earlier psychotherapy referral was associated with lower cancer-specific mortality.

• Frontline NPs and PAs are not secondary players here — your ability to identify, validate, and act on depressive symptoms may directly shape whether patients get timely support.

• If you catch depression early and connect the patient quickly, your referral may do more than improve coping; it may help improve survival.
