- W4281776906 abstract "e19566 Background: It is well known that age, stage, and performance status are important prognostic factors in predicting survival of patients diagnosed with lymphoid malignancies. At the VA Healthcare System, many patients have comorbidities and poor performance status. We evaluated the association of clinical outcomes with lymphoma stage, subtype and performance status in US Veterans. Methods: This retrospective study included patients diagnosed with a lymphoid malignancy including diffuse large B-cell lymphoma (DLBCL), chronic lymphocytic leukemia (CLL), follicular lymphoma (FL), marginal zone lymphoma (MZL), mantle cell lymphoma (MCL), and peripheral T-cell lymphoma (PTCL) from January 2008 - December 2021 at the VA Long Beach Healthcare System (n = 221). Endpoints included clinically relevant hematological and non-hematological adverse events (AE), and death from lymphoma (with death from other causes as competing events). Variables of interest included aggressive lymphomas (DLBCL and PTCL, n = 85) vs indolent lymphomas (CLL, FL, MZL and MCL, n = 149), stage (early [0-2] vs advanced [3-4]), age at diagnosis (continuous variable), and performance status (Eastern Cooperative Oncology Group [ECOG] scale: good [0-2] vs poor [3-4]). Logistic regression and Cox models with Fine and Gray competing risk were performed. Results: In patients receiving first line therapy, performance status, disease type, stage, and age at diagnosis did not predict development of clinically relevant AEs with an odds ratio [OR] of 4.1 (p = 0.12, 95% CI 0.70-24), 0.36 (p = 0.06, 95% CI 0.12-1.0), 1.5 (p = 0.39, 95% CI 0.58-4.0), and 1.0 (p = 0.12, 95% 0.99-1.1), respectively. Patients with worse performance status (ECOG 3-4) and advancing age did not have a statistically higher risk of dying from lymphoma vs other causes: performance status: HR 1.7, p = 0.26, 95% CI 0.67-4.3 and age: HR 1.02, p = 0.11, 95% CI 1.0-1.1. In a multivariate analysis, patients with more advanced stage and aggressive subtype were more likely to die from lymphoma vs other causes (hazard ratio [HR] 4.1; p < 0.001, 95% CI 2.2-7.8 and 3.1; p = < 0.0001, 95% CI 1.7-5.5), respectively. Conclusions: The fact that performance status may not predict the development of AEs with first line therapy for lymphoid malignancies is relevant to clinical decision making. However, our findings need confirmation in larger prospective studies." @default.
