Psychological Status • Prevalence up to 50% in patients with cancer • Clinical depression predicts severe treatment related-toxicity and overall survival • Depression diagnosed prior to and after diagnosis of cancer were associated with mortality Freyer G, et al. Ann Oncol. 2005 Pinquart M, et al. Psychol Med. 2010 Massie MJ. JNCI. 2004 Social Support Influence of marital status on breast cancer •Unmarried women were more likely to be diagnosed with breast cancer stage II-IV versus stage I or in situ •Unmarried women diagnosed with Stage I or II breast cancer were less likely to receive definitive treatment •Unmarried women were at increased risk of death from breast cancer Osborne C, et al. Breast Cancer Res Treat. 2005 All Older Patients with Cancer are Not the Same Oncology versus Geriatrics • Oncology stage the cancer – Make predictions of life expectancy – Expected side effects of cancer therapy • Geriatrics stage the “aging” – Make predictions of life expectancy – Anticipate potential complications – Better evaluate whether the benefits of therapy outweigh the risks in the context of physiologic age Chronologic versus Physiologic Age When considering prognosis and treatment options in this population, decisions should be based more on “physiologic” age versus chronologic age. It is necessary for oncologists to be adept at efficiently and accurately estimating physiologic and functional capacity in older patients. Conceptual Model of GA Comprehensive Geriatric Assessment • Functional status • Psychological status • Activities of daily Living • Depression/Anxiety • Instrumental activities of daily • Cognitive impairment living • Dementia • Physical function • Delirium • Falls • Nutrition • Comorbidities • Social support • Vision/hearing • Medications • Goals of Care • Polypharmacy • Frailty • Inappropriate medications Developing a Cancer-Specific Geriatric Assessment (CSGA): A Feasibility Study FEASIBILITY Time to complete ABILITY TO COMPLETE UNASSISTED Mean 27 min (SD 10) Range 8-45 min No: 22% No association of age with time to complete assessment (p = 0.13) Yes: 78% No association of age with ability to complete without assistance (p=0.16) Hurria A et al.

p= 0.82) Dose delays (42% vs 35%; p= 0.61) Pilot Study Results Consider meals-on-wheels – 33% Nutrition referral – 67% Consider PT/OT Referral – 33% Consider more aggressive antiemetic regimen – 50% Fall counseling handout – 44% Ride assistance programs – 50% Home safety evaluation – 39% Social work involvement – 80% Check vitamin D and repletion as indicated – 17% Identification of HCP– 30% Consider initial dose reduction – 72% Co-sign for consents – 10% Medication review – minimize psychoactive meds – Delirium risk handout – 30% 57% Pillbox – 19% PERS if alone – 0% Medication review – minimize high risk medications – Energy conservation handout – 36% Exercise handout – 36% Consider depression pharmacological therapy – 17% VNS/home health aide referral – 42% Consider referral for psychotherapy/psychiatry – 17% Nutrition counseling (handout) – 50% Support Group Information – 71% 36% Pilot Study Results 3-month follow up Depression •GA at 3 months demonstrated increased interval development of depression in the control group •(36% vs 5%; p = 0.02) Pilot Study Results 3-month follow up Function • Resolution of baseline differences in IADL dependence •(44% vs 42%; p=0.90) Pilot Study Discussion Conclusions: • Able to enroll older, advanced cancer patients to a clinical trial in a reasonable timeframe • Patients not being referred to the geri-onc clinic have a good deal of geriatric-related issues • Unfortunately, we weren’t able to see that the intervention algorithm improved the primary outcome – chemotherapy toxicity for patients • Did see improvements with regards to function and depression A Geriatric Assessment Intervention for Patients Aged 70 and Over Receiving Chemotherapy for Advanced Cancer: Reducing Chemotherapy Toxicity in Older Adults -GAP-70+: Funded by NCI R01 Study Chair Supriya Mohile, MD, MS, University of Rochester Study Co-Investigators Garry Morrow PhD, MS University of Rochester Karen Mustian PhD, MPH, University of Rochester Ron Epstein, MD, University of Rochester Arti Hurria, MD, City of Hope William Dale, MD, PhD, University of Chicago Primary Aim To determine if providing information regarding GA and GA-driven recommendations to oncologists reduces grade 3-5 chemotherapy toxicity in patients aged 70 and over with advanced solid tumor malignancy Conceptual Model Schema Summary • The population is aging • Older adults often have other comorbidities, geriatric syndromes, functional and cognitive impairment, polypharmacy and reduced social support • GA can help predict outcomes and decision-making • More data is needed on impact of GA-driven interventions on outcomes Acknowledgement New York Cancer Registrar’s Association Dr. Supriya Mohile Dr. Allison Magnuson 59
