Psychotherapy within four weeks linked to lower cancer mortality

A large-scale analysis of SEER-Medicare data involving over 265,000 adults has identified a significant link between depression and cancer mortality. The study, which focused on patients aged 66 or older diagnosed with breast, colorectal, prostate, bladder, kidney, or non-small cell lung cancer, found that those with major depressive disorder faced a higher risk of dying from cancer.

Crucially, the research indicates that early mental health intervention can improve survival rates. Patients who began psychotherapy within four weeks of their cancer diagnosis saw a 21% reduction in cancer-specific mortality risk. Despite this benefit, the study revealed a major gap in care: only 3% of analyzed patients received psychotherapy within that critical four-week window.

Lead author Edmund M. Qiao, MD, noted that depression is often overlooked in oncology because its symptoms—such as fatigue and loss of interest—overlap with the side effects of cancer and its treatments. The findings, which will be presented at the American Society for Radiation Oncology (ASTRO) Annual Meeting, suggest that improved screening and faster referrals for psychotherapy are essential for comprehensive cancer care.
