170 Background: Older age is a cause of disparity in cancer treatment decision and treatment guidelines for patients with comorbidities, polypharmacy, denutrition or psycho-social frailty are needed. A pre-therapeutic multidimensional assessment might improve the complex patient management. We developed an experimental program of integrated medicine called ARIANE. We report 18 months activity of this outpatient setting evaluation, its feasibility and impact on treatment decision-making. Methods: Complex patients with predefined cancer treatment strategy entered into the program. A one-day evaluation combined consultations of cardiologist, geriatrician, diabetologist, anesthetist, pharmacist, pain specialist, dietician, psychologist and social worker. Evaluation of performance status, EKG, ejection fraction, ASA score, diabetes, social vulnerability and malnutrition was performed including a geriatric assessment, which focused on items like comorbidity (CIRS-G), dependance (ADL, IADL), fails (Up and Go Test), cognitive impairment (MMSE, Clock Drawing Test) and depression (GDS scale). A pharmacist assessed the risk of drug-drug interactions. Results: Eighty-seven pts, median age 81 years (range 25-94), 76% male, 51% PS 0-1, 77% grade 3 or 4 comorbidity were included. Genito-urinary, lung cancers and sarcoma represented 77% of pts. Eighty-two percent of pts were assessed by at least ≥ 7 participants. Identified factors of vulnerability were polypharmacy (n=65; 75%; >3 drugs), social distress or severe malnutrition (both n=21; 24%), depression (n=17; 19.5%) and cognitive impairment (n=13; 15%). We identified drug interaction in 18 pts (27%). The risk assessment resulted in anticancer treatment changes in 47/87 patients (54%): protocol adaptation (n=19/87; 22%), less aggressive treatment (n=15/87; 17.2%), or more intensive therapy (n=13/87; 15%). Conclusions: A one-day multidisciplinary risk assessment is an answer to the complexity of unfit cancer patients and improves the safety of anticancer treatments.
