AbstractOur aim was to evaluate whether quality of life (QOL) scores at diagnosis predict survival among patients with aggressive lymphoma. Newly diagnosed lymphoma patients were prospectively enrolled within 9 months of diagnosis in the University of Iowa/Mayo Clinic SPORE and systematically followed for event‐free and overall survival (OS). QOL was measured with the Functional Assessment of Cancer Treatment‐General (FACT‐G), which measures 4 domains: physical, social/family, emotional, and functional well‐being (WB); a single item Linear Analogue Self‐Assessment (LASA) measuring overall QOL; and a spiritual WB LASA. From 9/2002 to 12/2009, 701 patients with aggressive lymphoma who completed baseline QOL questionnaires were enrolled. At a median follow‐up of 71 months (range 6‐128), 316 patients (45%) had an event and 228 patients (33%) died. All baseline QOL measures but emotional WB were significantly associated with OS (all P < 0.04); of which all but LASA spiritual remained significant after adjusting for IPI and NHL subtype. The strongest associations were with total FACT‐G (adjusted HR = 0.86, 95% CI: 0.79‐0.94, P = 0.00062) and functional WB (adjusted HR = 0.88, 95% CI: 0.83‐0.93, P < .0001). QOL LASA was associated with OS (adjusted HR = 0.92, 95% CI: 0.87‐0.97, P = 0.0041). Patients with clinically deficient QOL (overall QOL ≤50) had a median OS of 92 months compared with 121 months for patients with QOL >50 (P = 0.0004). In this large sample of patients with aggressive lymphoma, we found that baseline QOL is independently predictive of OS. QOL should be assessed as a prognostic factor in patients with aggressive lymphoma.

95 Background: While PA is known to improve quality of life in lymphoma pts, its impact on OS is not known. We studied the effect of PA on OS in lymphoma pts enrolled at diagnosis in the Iowa/Mayo Molecular Epidemiology Resource. Methods: Godin Leisure Score Index (LSI; Range 0-50) was calculated based on level of PA pre-diagnosis (baseline) and 3 years post diagnosis (FU3), with pts grouped by tertile into high, moderate, or low PA. At FU3, pts also reported perceived change in PA since diagnosis. OS was measured as time from assessment (baseline or FU3) until death from any cause. Associations between LSI tertiles and OS were assessed using Cox models adjusted for lymphoma subtype, age and sex. Results: PA level was available for 3060 pts at baseline and 1371 pts at FU3. 95% had an ECOG performance status < 2, 37% had an aggressive subtype, 29% had BMI ≥ 30, and 54% were age > 60. Indolent lymphoma pts with higher PA at baseline had no difference in OS. Higher PA at FU3 had improved OS (moderate vs low HR 0.63, CI 0.42-0.93; high vs low HR 0.53, CI 0.33-0.86). Pts with BMI < 30 who had higher PA at baseline showed no difference in OS. Higher PA at FU3 had improved OS for pts with BMI < 30 (moderate vs low HR 0.68 CI, 0.48-0.98; high vs low HR = 0.41, CI 0.26-0.64). For pts > 60 years, high vs low baseline PA showed improved OS (HR 0.77, CI 0.63-0.93). Higher PA at FU3 (moderate vs low HR 0.68 CI 0.48-0.96, high vs low HR 0.53 CI 0.34-0.83) was associated with OS. At FU3, compared to no change, perceived reduction of PA was associated with worse OS for indolent lymphoma (HR 2.13, CI 1.56-2.91), BMI < 30 (HR 1.95, CI 1.45-2.62), BMI > 30 (HR 2.00, CI 1.21-3.30), age ≤ 60 (HR 3.06, CI 1.72-5.46), and age > 60 (HR 1.98, CI 1.52-2.58). Perceived increase in PA was not associated with OS. Higher PA in pts with aggressive lymphoma, BMI ≥30, and age < 60 was not significantly associated with OS but trended similarly. All results were similar when analyzing by continuous LSI score. Conclusions: Higher levels of PA, especially at FU3, were associated with superior OS. The effect was more pronounced in pts with indolent lymphoma, BMI < 30, or age > 60. Perceived reduction in PA was associated with worse outcomes. PA should be incorporated into lymphoma survivorship plans.

Purpose Selection bias in clinical trials has consequences for scientific validity and applicability of study results to the general population. There is concern that patients with clinically aggressive disease may not have enrolled in recent diffuse large B-cell lymphoma (DLBCL) trials due to the consent process and the inability to delay therapy for eligibility evaluation. We have examined the diagnosis-to-treatment interval (DTI) and its association with clinical factors and outcome in a clinic-based observational cohort of patients with DLBCL from the United States. Validation of results was performed in an independent, clinical trial-based cohort from Europe. Patients and Methods Patients were prospectively enrolled in the University of Iowa and Mayo Clinic Specialized Programs of Research Excellence Molecular Epidemiology Resource (MER; N = 986) or the Lymphoma Study Association (LYSA) LNH-2003 clinical trials program (N = 1,444). All patients received anthracycline-based immunochemotherapy at initial diagnosis. Associations of DTI with clinical factors and outcome were examined. Outcome was assessed using event-free survival at 24 months from diagnosis (EFS24). Results Median (range) DTI was 15 days (0 to 155 days in the MER and 23 days (0 to 215 days) in LYSA. Shorter DTI was strongly associated with adverse clinical factors, including elevated lactate dehydrogenase levels, poor performance status, B symptoms, and higher International Prognostic Index in both cohorts (all P < .001). Longer DTI was associated with improved EFS24 in both the MER (per-week odds ratio, 0.80; 95% CI, 0.74 to .0.87) and LYSA (per-week odds ratio, 0.90; 95% CI, 0.86 to 0.94); association with EFS24 remained significant after adjustment for International Prognostic Index. Conclusion DTI is strongly associated with prognostic clinical factors and outcome in newly diagnosed DLBCL. DTI should be reported in all clinical trials of newly diagnosed DLBCL and future trials should take steps to avoid selection bias due to treatment delay.

BACKGROUNDEarly treatment failure (ETF) in follicular lymphoma (FL), defined as relapse or progression within 2 years of frontline chemoimmunotherapy, is a newly recognized marker of poor survival and identifies a high‐risk group of patients with an expected 5‐year overall survival (OS) rate of approximately 50%. Transplantation is an established option for relapsed FL, but its efficacy in this specific ETF FL population has not been previously evaluated.METHODSThis study compared autologous hematopoietic stem cell transplantation (auto‐HCT) with either matched sibling donor (MSD) or matched unrelated donor (MUD) allogeneic hematopoietic cell transplantation (allo‐HCT) as the first transplantation approach for patients with ETF FL (age ≥ 18 years) undergoing auto‐HCT or allo‐HCT between 2002 and 2014. The primary endpoint was OS. The secondary endpoints were progression‐free survival, relapse, and nonrelapse mortality (NRM).RESULTSFour hundred forty FL patients had ETF (auto‐HCT, 240; MSD hematopoietic stem cell transplantation [HCT], 105; and MUD HCT, 95). With a median follow‐up of 69 to 73 months, the adjusted probability of 5‐year OS was significantly higher after auto‐HCT (70%) or MSD HCT (73%) versus MUD HCT (49%; P = .0008). The 5‐year adjusted probability of NRM was significantly lower for auto‐HCT (5%) versus MSD (17%) or MUD HCT (33%; P < .0001). The 5‐year adjusted probability of disease relapse was lower with MSD (31%) or MUD HCT (23%) versus auto‐HCT (58%; P < .0001).CONCLUSIONSPatients with high‐risk FL, as defined by ETF, undergoing auto‐HCT for FL have low NRM and a promising 5‐year OS rate (70%). MSD HCT has lower relapse rates than auto‐HCT but similar OS. Cancer 2018;124:2541‐51. © 2018 American Cancer Society.

Key Points SCHOLAR-1 is the first patient-level analysis of outcomes of refractory DLBCL from 2 large randomized trials and 2 academic databases. SCHOLAR-1 demonstrated poor outcomes in patients with refractory DLBCL, supporting a need for more effective therapies for these patients.

AbstractBackgroundCentral nervous system (CNS) relapse in non‐Hodgkin lymphoma (NHL) is a rare but serious complication that carries a poor prognosis. The use of infusional etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab (EPOCH‐R) for frontline treatment of diffuse large B cell lymphoma (DLBCL) is increasing, though little is known about incidence of and risk factors for CNS relapse with this regimenPatients and methodsWe completed a chart review of patients with NHL who received EPOCH‐R as front line therapy. Data obtained included baseline and treatment characteristics including if patients received CNS directed therapy. We measured overall survival (OS), progression free survival (PFS), and progression to CNS involvement.ResultsWe identified 223 patients who met the inclusion criteria, 72% had DLBCL. Of all the patients, 5.8% experienced CNS relapse, and 38.6% were treated with CNS prophylaxis. There was no difference in rate of CNS relapse, OS, or PFS between patients who had and had not received CNS prophylaxis. Patients whose serum lactate dehydrogenase was greater than twice the upper limit of normal at diagnosis and those with extranodal disease were significantly more likely to have CNS relapse (P = .0247 and 0.022, respectively) than their counterparts.ConclusionsThe rate of CNS relapse in this patient population approaches 6%, not significantly different from reports on those receiving R‐CHOP. The results of this study suggest that CNS prophylaxis might be more selectively used among patients treated with EPOCH‐R with certain high‐risk features.

Summary This study aimed to describe the patterns of care and outcomes of diffuse large B cell lymphoma ( DLBCL ) after failure of front line anthracycline‐based immunochemotherapy ( IC ). Patients with newly diagnosed lymphoma were prospectively enrolled in Molecular Epidemiology Resource ( MER ) of the University of Iowa/Mayo Clinic Lymphoma Specialized Program of Research Excellzence. All DLBCL and primary mediastinal B‐cell lymphoma ( PMBL ) patients treated with front‐line anthracycline‐based IC were followed for relapse. Patients with relapse on follow‐up and subsequently retreated were included in this analysis. 1039 patients received anthracycline‐based IC between 2002 and 2012, of which 244 relapsed and were subsequently retreated. Across all therapies, overall survival at 4 years ( OS 4) from relapse was 28% and 103 patients ultimately underwent autologous haematopoietic cell transplant (auto HCT ) with OS 4 from auto HCT of 51%. Patients relapsing after 12 months from initial diagnosis had OS 4 of 47% but those with a transient or no response to initial therapy had OS 4 of only 13%. Outcomes of relapsed or refractory DLBCL differ substantially when categorized by response to initial therapy, timing of relapse and opportunity to undergo auto HCT . The design and interpretation of uncontrolled trials should account for this heterogeneity in patients with relapsed DLBCL .

193 Background: National standards recommend distress screening as part of cancer care. While many patients report improved quality of life after cancer treatment concludes there remains a population who experience ongoing anxiety and depressive symptoms. We sought to describe psychosocial distress in lymphoma survivors and frequency of visits to mental health providers (MHP). Methods: Lymphoma patients were prospectively enrolled within 9 months of diagnosis in the University of Iowa/Mayo Clinic SPORE Molecular Epidemiology Resource and systematically followed. Brief Profile of Mood States (POMS) and State Trait Anxiety Inventory (STAI) were administered 3 yrs after diagnosis. Lower scores on POMS indicated more distress. A higher score on STAI indicated more anxiety, and a score ≥ 40 was considered clinically significant. Pts were asked if they ever saw a MHP due to their lymphoma. Results: Between 2002-2012, 2465 lymphoma pts age 18-91 (10% 18-40, 54% 41-65, and 36% > 65) were enrolled, met survivor definition, and completed 3-yr POMS and STAI questionnaires. 57% were male. 40% had aggressive and 60% had indolent lymphoma. The median score on STAI 1 (state) was 32 (range 20-76) and on STAI 2 (trait) was 31 (range 20-77). Median POMS total mood disturbance (TMD) score was 88 (range 1-100). 8% of pts reported seeing a MHP. 609 pts (25%) had clinically significant anxiety by STAI 1, 73 (12%) of whom saw a MHP. Those who reported clinically significant anxiety on STAI were more likely to be younger, unemployed, unmarried, and less likely to have seen a MHP. Anxiety levels were similar between those with aggressive lymphoma and indolent lymphoma regardless of treatment. Higher distress levels, measured by TMD, were more often reported by those who were unemployed or over age 65 while there was no association with lymphoma subtype, marital status, or choice of therapy. Conclusions: Clinically significant anxiety was reported in 25% of 3-yr survivors of lymphoma and was associated with younger age, unmarried status, and unemployment. Higher distress levels were associated with older age, and unemployment. However, only 8% of our cohort was seen by a MHP. Identifying distress and appropriately referring to a MHP is important for the optimal care of lymphoma survivors.
