In the study, the geriatric assessment-driven interventions included recommendations from a multidisciplinary team based on the patients' baseline geriatric assessment. These recommendations likely encompassed personalized strategies to address the specific needs and vulnerabilities of older adults with cancer, including those related to mental health. By tailoring interventions based on the individual's assessment, the team could provide targeted support to manage depression symptoms effectively. This personalized approach may have included psychosocial support, counseling, or referrals to mental health professionals, which could have helped in mitigating the increased risk of chemotherapy toxicity associated with depression.
