BPI19-011: Assessment and Management of Older Patients With Metastatic Breast Cancer (MBC) Among Community Oncologists in the United States

Restricted access

Introduction: Geriatric assessment (GA) is recommended for evaluating an older cancer patient’s fitness for treatment; however, it is underutilized in the community. We sought to define the gaps that exist in community oncology practices in the assessment and management of older MBC patients through implementation and training on the use of GA for the care of older MBC patients. Methods: The first phase evaluated community oncology providers using questionnaires regarding their assessment and management of older MBC patients. The second phase included training through implementation of a patient self-administered GA among patients ≥65-years-old with MBC. The providers were blinded to the results of the GA and provided their assessment. Comparison of the 2 evaluations was conducted. The GA was ultimately shared with the providers, who were questioned about the effect of the results on care recommendations. Results: 43 providers from 10 practices were enrolled. Phase I revealed the majority (77%) of providers recognized the utility of GA, yet only 42% routinely conducted a GA pretreatment. Most providers (77%) reported evaluating various GA domains through patient interview rather than validated assessments. Validated scales were used in low rates to evaluate cognition (23%), psychosocial status (12%), and toxicity risk (9%). The limited use of validated assessment tools was not influenced by the provider’s demographics or their views of GA utility. Eighty patients took part in the training phase of the study to date, with average age 74 (range, 65–90) and 84% Caucasian. The majority of patients had subtype ER/PR+, HER2- (75%) and 46% were on first-line therapy. 277 recommended interventions were identified: 174 immediate interventions and 103 suggested interventions. Following review of these results, providers reported being surprised in 40% of the cases, mainly with lower than expected cognitive or social support scores. The providers reported plans for change in management in 44% of the patients as a result of the GA findings. Conclusion: Despite acknowledgement of the value associated with pretreatment GA, it is rarely used in the community. Furthermore, interview rather than validated assessment tools are used to identify age-related concerns. In our preliminary results, the GA identified a large number of deficient areas that had not been identified through the provider’s assessment, and resulted in management change. Additional updated results will be presented at the conference.
