Phase Ib trial of lenalidomide as post-remission therapy for older adults with acute myeloid leukemia: Safety and longitudinal assessment of geriatric functional domains.

BACKGROUND AND OBJECTIVES: Novel, non-cytotoxic agents are driving a paradigm shift for treatment of older adults with acute myeloid leukemia (AML). Older patients who initially receive intensive cytotoxic induction may choose to not proceed with cytotoxic consolidation therapy. Lenalidomide is an orally-administered immunomodulatory small molecule with activity in AML and a favorable safety profile in older adults with active leukemia. We conducted a phase Ib study of lenalidomide as post-remission therapy in older adults and assessed its impact on geriatric functional domains. MATERIALS AND METHODS: Participants were patients with AML over age 60 years who had undergone induction therapy and were poor candidates for cytotoxic consolidation. Lenalidomide was administered for 28 days in three dose cohorts. A Bayesian dose-escalation method determined cohort assignment and maximum tolerated dose (MTD). Geriatric assessment (GA) was performed before and after the cycle of lenalidomide. RESULTS: Nineteen patients with median age 68 were treated with at least one 28-day course of lenalidomide. Dose-limiting toxicities were observed in three participants at 25 mg, zero participants at 35 mg, and one participant at 50 mg. MTD was 35 mg. Median relapse-free survival was 4.3 months. GA was completed before and after treatment in fifteen patients, demonstrating improved cognitive function and no changes in physical, psychological, or social function after lenalidomide. CONCLUSION: Lenalidomide can be safely administered to older adults with AML with preservation of functional domains important to older patients. Serial GA can be performed in a novel drug study as a tool to characterize treatment tolerability.

Serial Assessment of Depression and Anxiety by Patients and Providers in Women Receiving Chemotherapy for Early Breast Cancer.

BACKGROUND: Depression and anxiety are common in patients with breast cancer and associated with worse quality of life and treatment outcomes. Yet, these symptoms are often underrecognized and undermanaged in oncology practice. The objective of this study was to describe depression and anxiety severity and associated patient factors during adjuvant or neoadjuvant chemotherapy in women with early breast cancer using repeated single-item reports. MATERIALS AND METHODS: Depression and anxiety were measured from consecutive patients and their clinicians during chemotherapy infusion visits. Associations between psychiatric symptoms and patient characteristics were assessed using Fisher's exact tests for categorical variables and t tests for continuous variables. The joint relationship of covariates significant in unadjusted analyses was evaluated using log-binomial regression. Cohen's kappa was used to assess agreement between patient- and clinician-reported symptoms. RESULTS: In a sample of 256 patients, 26% reported at least moderately severe depression, and 41% reported at least moderately severe anxiety during chemotherapy, representing a near doubling in the prevalence of these symptoms compared with before chemotherapy. Patient-provider agreement was fair (depression: κ = 0.31; anxiety: κ = 0.28). More severe psychiatric symptoms were associated with being unmarried, having worse function, endorsing social activity limitations, using psychotropic medications, and having a mental health provider. In multivariable analysis, social activity limitations were associated with more severe depression (relative risk [RR], 2.17; 95% confidence interval [CI], 1.36-3.45) and anxiety (RR, 1.48; 95% CI, 1.05-2.09). CONCLUSION: Oncologists frequently underestimate patients' depression and anxiety and should consider incorporating patient-reported outcomes to enhance monitoring of mental health symptoms. IMPLICATIONS FOR PRACTICE: In this sample of 256 patients with breast cancer, depression and anxiety, measured using single-item toxicity reports completed by patients and providers, were very common during adjuvant or neoadjuvant chemotherapy. Patient-reported depression and anxiety of at least moderate severity were associated with multiple objective indicators of psychiatric need. Unfortunately, providers underrecognized the severity of their patients' mental health symptoms. The use of patient-reported, single-item toxicity reports can be incorporated into routine oncology practice and provide clinically meaningful information regarding patients' psychological health.
