AbstractMantle cell lymphoma is characterized by relapse and progressive disease, despite initial response to chemoimmunotherapy. We conducted a systematic review and meta‐analysis to determine the efficacy of rituximab maintenance (RM) therapy in patients with mantle cell lymphoma. We searched PubMed, Embase and Cochrane Central Register of Controlled Trials from database inception through November 1, 2017. Only full‐text articles were included. Prespecified data elements were extracted from each trial. Outcomes of interest included progression‐free survival (PFS) and overall survival (OS). The overall effect was pooled using the Der Simonian‐Laird random effects model. Three randomized controlled trials and four observational studies met our inclusion criteria and were identified in the analyses. Six studies compared RM therapy to observation, and one compared RM therapy to interferon alfa. Meta‐analysis evaluating outcomes of patients treated after ASCT revealed that RM improved for both PFS (HR = 0.33, 95% CI = 0.23‐0.49) and OS (HR of death = 0.35, 95% CI = 0.17‐0.69). A second meta‐analysis of studies evaluating outcomes of patients who are ASCT‐ineligible treated with anthracycline‐based induction therapy revealed that RM improved PFS (HR = 0.38, 95% CI = 0.25‐0.58). There is a paucity of data on the role of RM in ASCT‐ineligible patients and those with relapsed disease. Overall, RM therapy appears to improve PFS and OS in previously untreated patients with mantle cell lymphoma who undergo induction chemoimmunotherapy followed by ASCT.

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.

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.

64 Background: The goals of our Lymphoma Survivorship Clinic (SC) are to coordinate care, educate patients, and create a survivorship care plan (SCP). The aim of this study was to determine if patient-centered outcomes are improved after a SC visit. Methods: From 11/13-5/15, surveys were mailed to recently-treated lymphoma patients who were within 4 weeks of their last visit and in remission. Quality of life (QOL) was measured with PROMIS and distress was measured with the Impact of Events scale. Responses between those who attended SC and those who were eligible but did not attend were analyzed. Results: There were 96 surveys sent to the SC group; 59 were returned (61% response rate). Of the non-SC group, 140 surveys were sent and 84 were returned (60% response rate). Mean age was 57 years (range 23-77) in the SC group and 59 years (23-88) in the non-SC group. There were more females in the SC group (52% vs 30%) but no differences in race, marital status, education, or health literacy. Those who attended the SC were more likely to recall receiving a summary of cancer treatment and recommendations for follow-up care (90% SC vs. 75% non-SC, p = 0.03). Furthermore, SC attendees were more likely to “definitely” recall discussion on improving health or preventing illness (89% vs. 53%), getting help in making changes in habits/lifestyle (76% vs. 50%), diet (80% vs. 31%), and exercise (82% vs. 51%), all p < 0.001. There were no differences in discussions regarding smoking, follow-up testing, and symptom monitoring. The SC group was less likely to need more information regarding sexuality (6% vs 20%, p = 0.045). There were no differences in need for information regarding anxiety, fitness, familial cancer risk, fertility, complementary therapies, and social issues. The SC group was slightly more confident that they could get information or advice related to cancer (completely confident 76% vs. 61%, p = 0.07). There were no differences in QOL or distress. Conclusions: A Lymphoma SC visit increased receipt of SCP and provided more information on survivorship issues, particularly health behaviors, but did not improve QOL or distress. Further study is needed to determine if this leads to long-term health benefits.

236 Background: Patients (pts) with aggressive lymphoma are generally treated with curative intent and many become long-term survivors. There is little data on health behaviors after lymphoma diagnosis and their effect on QOL and long-term outcomes. Methods: Lymphoma pts were prospectively enrolled within 9 months of diagnosis in the University of Iowa/Mayo Clinic SPORE Molecular Epidemiology Resource (MER) and systematically followed. We measured QOL (FACT-G) and health behaviors (tobacco/alcohol use; diet/exercise habits) 3 years after diagnosis. For this study, “survivor” was defined as alive at 3 years from diagnosis with no active disease or treatment within the previous year. Results: From 2002-2012, 671 patients with aggressive lymphoma were enrolled, met survivor definition, and completed 3-year QOL and health behavior questionnaires. At 3-years, 31% of female (F) and 48% of male (M) reported a history of tobacco use for 6+ months. Of these, 13% of F and 7% of M were still smoking; 52% reported decreased use from baseline. 66% reported no change in alcohol intake at 3-years while 25% of F and 34% of M reported decreased intake. 60% often chose whole grains and 65% get 2+ servings of vegetables daily. 42% of F and 38% of M “somewhat” believed diet could change the course of their lymphoma. Most pts endorsed no significant change in diet as a result of diagnosis. Those who made changes did so primarily out of concern for “health problems other than cancer”. Overweight/obese responders were 72% pre- and 66% post-treatment. A desire to lose weight was reported by 55% of pts. 14% of F and 23% of M often engaged in regular physical activity (PA). Nearly 50% reported a decrease in PA. Pts with advanced stage (p = 0.006), age > 60 (p = 0.001), ECOG PS > 2 (p = 0.04), and worse prognostic score (p = 0.006) were more likely to report decreased PA since diagnosis. 68% of F and 61% of M intend to become more active in the next months. Regular PA (p = < 0.0001) was associated with higher QOL, while increased alcohol intake was associated with lower QOL (p = 0.009) at 3 years. Conclusions: Many survivors of aggressive NHL strive to adopt healthy behaviors and these behaviors are associated with higher QOL. Interventions aimed at emphasizing these behaviors may have potential to improve long-term outcomes and QOL.

AbstractPatients with indolent non‐Hodgkin lymphoma (NHL) have multiple treatment options yet there is no consensus as to the best initial therapy. Lenalidomide, an immunomodulatory agent, has single agent activity in relapsed lymphoma. This trial was conducted to assess feasibility, efficacy, and safety of adding lenalidomide to rituximab, cyclophosphamide, and dexamethasone (LR‐CD) in untreated indolent NHL patients requiring therapy. This was a single institution phase II trial. Treatment consisted of IV rituximab 375 mg/m2 day 1; oral lenalidomide 20 mg days 1–21; cyclophosphamide 250 mg/m2 days 1, 8, and 15; and dexamethasone 40 mg days 1, 8, 15, and 22 of a 28‐day cycle. Treatment continued 2 cycles beyond best response for a maximum of 12 cycles without rituximab maintenance. Thirty‐three patients were treated. Median age was 68 (43–83 years). 39% had stage IV disease. Histologic subtypes included 8 follicular lymphoma (FL), 7 marginal zone lymphoma (MZL) (1 splenic, 2 extranodal, and 4 nodal), 15 Waldenström's macroglobulinemia (WM), 1 lymphoplasmacytic lymphoma, 1 small lymphocytic lymphoma, and 1 low‐grade B‐cell lymphoma with plasmacytic differentiation (unable to be classified better as MZL or LPL). Hematologic toxicity was the most common adverse event. Median time of follow‐up was 23.4 months (range 1.8–50.9). The overall response rate was 87.9%, with 30.3% complete response. The median duration of response was 38.7 months. The median progression free survival was 39.7 months, while median overall survival (OS) has not yet been reached. Lenalidomide can be safely added to a simple regimen of rituximab, oral cyclophosphamide, and dexamethasone and is an effective combination as initial therapy for low‐grade B‐cell NHL.
