Abstract
INTRODUCTION/BACKGROUND Leveraging the Follicular Lymphoma Analysis of Surrogacy Hypothesis database of individual patient data from first-line clinical trials, we studied the clinical course of follicular lymphoma (FL) and investigated clinical factors associated with FL outcomes. PATIENTS AND METHODS We examined 2428 patients from 8 randomized trials using multistate survival models with 4 states: induction treatment, progression, death from FL, and death from other causes. We utilized Aalen-Johansen estimator and Cox models to assess the likelihood of FL outcomes and quantify predictors' effects. RESULTS Two-year progression, FL-related death, and death from other causes estimates were 26.5%, 3.4% and 1.4%, respectively. FL-associated deaths were the primary cause of mortality within 10 years of follow-up. Male sex (hazard ratio: 1.25; 95% confidence interval: 1.05-1.47), > 4 involved nodal areas (1.51; 1.23-1.86), elevated LDH (1.20; 1.01-1.43), low hemoglobin (1.44; 1.15-1.81), and elevated β-2 levels (1.23; 1.02-1.47) increased risk of progression. CD20-targeting agents reduced risks for progression (0.29; 0.22-0.39), death from FL (0.05; 0.01-0.20), and death from other causes without progression (0.13; 0.05-0.33) and following progression (0.52; 0.30-0.92). Estimated 2-year progression rates were 22.3% and 43.5% with or without CD20-targeting agents, respectively. Two-year FL-associated mortality rate was 8.3% among patients without CD20-targeting agents, 5.4% with B-symptoms, 4.9% with elevated LDH, and 9.1% with low hemoglobin. CONCLUSION This study identified independent contributions of baseline clinical factors to distinct outcomes for patients with FL following first-line therapy on a clinical trial. Similar analytical approaches are needed to increase understanding of factors that influence FL outcomes in other settings.

Abstract
BACKGROUND One key clinical challenge remains in how to sequence treatments in follicular lymphoma (FL). The chemoimmunotherapy rituximab cyclophosphamide, doxorubicin, vincristine (Oncovin), and prednisone (R-CHOP) has been a standard treatment option for two decades. However, there are limited data to suggest in which line R-CHOP should be used for older patients. PATIENTS AND METHODS We leveraged population-based surveillance, epidemiology, and end results-medicare data and identified 675 patients aged ≥65 years newly diagnosed with FL from 2000 to 2009 who received R-CHOP in either the first or second line. We estimated restricted mean survival time using Kaplan-Meier curves, propensity scores (PS), and regression models comparing patients who received R-CHOP as a first versus second line. RESULTS We found that patients who received R-CHOP as first line had significantly longer 9-year RMST than those who received R-CHOP in the second line using Kaplan-Meier curves (P = .01), PS stratification (P = .002), PS matching (P = .005), and the inverse of PS as the treatment weight (P < .0001). The subgroup analyses using linear regression models showed that the 9-year restricted mean survival time of patients who received R-CHOP as the first line was longer in patients aged ≥80 years (P = .002) and with histological grade 1 or 2 (P = .02), compared to those who received R-CHOP as second line. CONCLUSION R-CHOP given in the first line was associated with longer overall survival compared to R-CHOP given as second line for older patients with FL.

SIRPα+ macrophages are increased in patients with FL who progress or relapse after frontline lenalidomide and rituximab. Blood Adv 2022; 6:3286-3293. [PMID: 35359004 PMCID: PMC9198921 DOI: 10.1182/bloodadvances.2022007104] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Accepted: 03/08/2022] [Indexed: 11/20/2022] Open
Abstract
Chemoimmunotherapy is an effective treatment strategy for patients with FL who relapse after frontline R2. SIRPα+ and CSF1R+macrophages are increased in FL patients who relapse after frontline R2.
Limited data exist regarding the outcome of patients with follicular lymphoma (FL) who relapse or progress after frontline lenalidomide and rituximab (R2). Moreover, mechanisms of resistance to R2 in FL remain unclear, with increased protumoral macrophages suspected as a major contributory culprit to this phenomenon. This retrospective study analyzed the outcome of patients with advanced-stage FL grade 1 to 3A who relapsed or progressed after frontline R2. A multiplex immunofluorescence macrophage panel, including CD47, CD14, CD68, CD115 (also known as colony-stimulating factor 1 receptor [CSF1R]), CD163, CD172a (also known as signal regulatory protein α [SIRPα]), and CD274 (also known as programmed cell death-ligand 1 [PDL1]), was used to stain tissue biopsy specimens collected before initiation of R2 and at the time of progression. Among 156 patients with advanced-stage FL treated with frontline R2, 33 (21%) relapsed or progressed and required second-line therapy, after a median of 33 months (range, 1-122 months). Second-line therapy was chemoimmunotherapy in 16 (48%) patients and other therapy in 17 (52%). The overall response rate was 78%, and complete response rate was 72%. Median progression-free survival was significantly longer in patients who received chemoimmunotherapy compared with other therapy (99 vs 25 months; P = .004). Three macrophage populations were significantly increased in tissue samples collected at progression compared with before frontline treatment: CD68+CD115+ (P = .02), CD68+CD115+CD172a+ (P = .02), and CD68+CD163+CD172a+ (P = .01). Chemoimmunotherapy is an effective treatment strategy for patients with FL who relapse after frontline R2. Therapies targeting specific macrophage populations may yield novel approaches for improving outcomes with frontline R2.

[PMID: 34273085 DOI: 10.1007/s40273-021-01052-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Accepted: 06/02/2021] [Indexed: 06/13/2023]
Abstract
BACKGROUND AND OBJECTIVE The objective of this study was to estimate the lifetime costs of patients receiving treatment for follicular lymphoma (FL) in the United States. METHODS A Markov model was programmed in hēRo3 with a 6-month cycle length, 35-year time horizon (lifetime projection), and health states for line of treatment, response, receipt of maintenance therapy among responders, transformation to diffuse large B-cell lymphoma (DLBCL), development of second primary malignancy (SPM), and death. The model was used to estimate the expected lifetime costs of FL (in 2019 USD), including costs of drug acquisition and administration, transplant procedures, radiotherapy, adverse events, follow-up, DLBCL, SPM, end-of-life care, and indirect costs. Model inputs were based on published sources. RESULTS In the US, patients with FL receiving treatment have a life expectancy of approximately 14.5 years from initiation of treatment and expected lifetime direct and indirect costs of US$515,884. Costs of drugs for induction therapy represent the largest expenditure (US$233,174), followed by maintenance therapy costs (US$88,971) and terminal care costs (US$57,065). Despite the relatively advanced age of these patients, indirect costs (due to patient morbidity and mortality and caregiver lost work time) represent a substantial share of total costs (US$40,280). Treated FL patients spend approximately 6.9 years in the health states associated with first-line therapy. Approximately 66 and 46% continue to second- and third-line therapies, respectively. The mean (95% credible interval) of expected lifetime costs based on the probabilistic sensitivity analyses was US$559,202 (421,997-762,553). CONCLUSIONS In the US, the expected lifetime costs of care for FL patients who receive treatment is high. The results highlight the potential economic benefits that might be achieved by treatments for FL that prevent or delay disease progression.

Characterizing Lymphoma Incidence and Disparities for a Cancer Center Catchment Region. CLINICAL LYMPHOMA MYELOMA & LEUKEMIA 2019; 19:699-708.e5. [PMID: 31494062 DOI: 10.1016/j.clml.2019.06.009] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/21/2019] [Revised: 06/07/2019] [Accepted: 06/17/2019] [Indexed: 01/06/2023]
Abstract
BACKGROUND Racial disparities in non-Hodgkin lymphoma (NHL) are not well-elucidated for specific catchment areas, which can influence outcomes. Leveraging regional data from a population-based cancer registry may provide unique opportunities to quantify NHL disparities. MATERIALS AND METHODS Using Surveillance, Epidemiology, and End Results (SEER) data for NHL cases diagnosed in Georgia from 2001 to 2015, we examined NHL incidence rates by lymphoma subtype and racial differences in baseline characteristics and outcomes for diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL). Cox regression models identified predictors of overall survival (OS). RESULTS SEER documented 38,504 NHL cases in Georgia from 2001 to 2015. The age-adjusted incidence rate for NHL in Georgia increased 1.03% per year, and the annual percentage change was 1.72 in blacks compared with 0.84 in whites. Compared with whites, blacks with DLBCL and FL were more likely to be diagnosed at a younger age (DLBCL, 54.1 vs. 65.5 years; P < .0001; FL, 58.4 vs. 64.0 years; P < .0001) and with B symptoms (DLBCL, 44.4% vs. 33.4%; P < .0001; FL, 28.5% vs. 21.4%; P = .004). Across racial categories, age at diagnosis > 60 years, advanced stage, and B symptoms predicted worse OS in DLBCL and FL. Blacks with DLBCL more commonly were diagnosed with stage III/IV disease (55.5% vs. 48.1%; P < .0001) and had worse 5-year relative survival (58.8% vs. 62.3%; P = .01). CONCLUSIONS Regional cancer registry data can be used to define incidence patterns and disparities in outcomes across NHL subtypes to help define key targets for interventions in a catchment area.
