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.

PURPOSE: To study the prognostic value of plasmablastic morphology after autologous stem-cell transplantation for relapsed or primary refractory myeloma. PATIENTS AND METHODS: Seventy-five patients were studied. Investigators blinded to the clinical details of the individual cases reviewed bone marrow aspirate slides to determine plasmablastic classification. Plasmablasts were defined using strict, well-described criteria. Plasmablastic morphology was considered to be present (plasmablastic myeloma) when 2% or more plasmablasts were present in the plasma-cell population. RESULTS: Patients underwent transplantation 5 to 88 months (median, 20 months) after the initial diagnosis of myeloma. Twenty-eight percent of patients had plasmablastic morphology. A significantly greater proportion of patients with plasmablastic morphology had abnormal cytogenetics compared with those with nonplasmablastic classification (73% v 31%, respectively; P = .003). The overall survival rate measured from the time of transplantation was significantly worse in patients with plasmablastic morphology compared with those without (median survival time, 5 months v 24 months, respectively; P < .001). Progression-free survival time was shortened also, with a median time of 4 months compared with 12 months, respectively (P < .001). In the multivariate analysis, plasmablastic classification was the most powerful prognostic factor after transplantation for both overall (P = .001) and progression-free survival rates (P < .001). We also identified three risk groups based on plasmablastic morphology: plasma-cell labeling index, lactate dehydrogenase, and cytogenetics. The median overall survival time was 38 months when none of these factors was abnormal, 17 months with one abnormal factor, and 8 months with two or more abnormal factors (P < .001). CONCLUSION: Plasmablastic morphology is a powerful independent predictor of poor survival rate after autologous stem-cell transplantation for relapsed or primary refractory myeloma.

PURPOSE: Previous studies in patients with non-Hodgkin’s lymphoma (NHL) and other malignancies have suggested that the presence of host infiltrates in the tumors of these patients may predict a better outcome. This study was undertaken to determine the prognostic importance of the presence of T cells in the biopsy specimens of patients with B-cell NHL.PATIENTS AND METHODS: Seventy-two patients with diffuse large B-cell NHL were prospectively evaluated at a single institution between 1987 and 1994. The percentage of CD3+, CD3+/HLA-DR+, CD4+, CD8+, and natural killer cells was determined by flow cytometry in the pretreatment diagnostic biopsy specimen and correlated with patient outcome.RESULTS: An increase in the percentage CD4+ T cells in the pretreatment tumor biopsies significantly correlated with patient outcome. The percent of CD4+ T cells was also highly correlated with CD3+/HLA-DR+, CD45RO+, and low l-selectin (CD62L) expression, indicating that the CD4+ T cells are activated memory T-helper cells. Those patients with increased numbers of CD4+ T cells, compared with other patients, had a significantly longer 5-year failure-free survival (72% v 43%, respectively; P = .04), as well as a significantly longer 5-year overall survival (65% v 38%, respectively; P = .05). When evaluated in a multivariate model, the International Prognostic Index and more than 20% infiltrating CD4+ T cells in the pretreatment biopsy were significant independent predictors of relapse-free and overall survival.CONCLUSION: The presence of increased numbers of activated CD4+ cells in the area of B-cell diffuse large-cell NHL predicts a better prognosis. This finding provides a strong rationale for the investigation of cellular immunotherapy in B-cell NHL.

PURPOSE: Based on the success of hematopoietic stem-cell transplantation (HSCT) for multiple myeloma, HSCT is being used to treat patients with primary systemic amyloidosis (AL). This article addresses the extent to which eligibility to undergo HSCT is a favorable prognostic feature and explores prognostic factors within the subset of eligible patients. PATIENTS AND METHODS: The Mayo Clinic amyloid database was queried for all patients with AL seen at the Mayo Clinic from 1983 through 1997 who would have been eligible for peripheral-blood stem-cell transplantation. Inclusion criteria included biopsy-proven amyloid, symptomatic disease, absence of a clinical diagnosis of multiple myeloma, age ≤ 70 years, cardiac interventricular septal thickness ≤ 15 mm, cardiac ejection fraction more than 55%, serum creatinine ≤ 2 mg/dL, and direct bilirubin ≤ 2.0 mg/dL. RESULTS: Median age was 56 years (range, 25 to 70) with 79 (34%) older than 60 years. One hundred patients had early cardiac involvement; 41, hepatic involvement; 167, renal involvement; and 39, nerve involvement. The 229 patients have had a median follow-up of 52 months, and 151 have died. The median survival was 42 months with 5- and 10-year survival rates of 36% and 15%, respectively. Important predictors of survival were size of M-component in 24-hour urine, number of involved organs, alkaline phosphatase, performance score, and weight loss. CONCLUSION: The same patients who are eligible for HSCT are a good-risk population who do relatively well with chemotherapy (median survival, 42 months), substantially better than the expected median survival of 18 months for all patients with AL. A randomized trial is needed to assess the true effect of HSCT.

PURPOSE: Primary systemic amyloidosis is an immunoglobulin deposition disorder in which insoluble light chains cause organ dysfunction and death. The established conventional therapy is treatment with melphalan and prednisone. We investigated whether treatment with multiple alkylating agents improved the response rate or survival time, compared with melphalan and prednisone therapy. PATIENTS AND METHODS: We treated 101 patients with biopsy-proven primary amyloidosis. The patients were randomly assigned to receive melphalan and prednisone (52 patients) or vincristine, carmustine, melphalan, cyclophosphamide, and prednisone (49 patients). Patients were stratified according to the presence of cardiac involvement, time from diagnosis to randomization, serum beta2-microglobulin level, and whether peripheral neuropathy was the major manifestation of the disease. RESULTS: The median duration of survival after randomization was 29 months, with no differences in survival time between the two groups. There were 29 patients who fulfilled the response criteria: 15 in the vincristine, carmustine, melphalan, cyclophosphamide, and prednisone arm and 14 in the melphalan and prednisone arm. CONCLUSION: Therapy with multiple alkylating agents did not result in a higher response rate or longer survival time, compared with standard melphalan and prednisone treatment in patients with primary systemic amyloidosis.

PURPOSE: Yttrium-90 ibritumomab tiuxetan (IDEC-Y2B8) is a murine immunoglobulin G1 kappa monoclonal antibody that covalently binds MX-DTPA (tiuxetan), which chelates the radioisotope yttrium-90. The antibody targets CD20, a B-lymphocyte antigen. A multicenter phase I/II trial was conducted to compare two doses of unlabeled rituximab given before radiolabeled antibody, to determine the maximum-tolerated single dose of IDEC-Y2B8 that could be administered without stem-cell support, and to evaluate safety and efficacy.PATIENTS AND METHODS: Eligible patients had relapsed or refractory (two prior regimens or anthracycline if low-grade disease) CD20+B-cell low-grade, intermediate-grade, or mantle-cell non-Hodgkin's lymphoma (NHL). There was no limit on bulky disease, and 59% had at least one mass ≥ 5 cm.RESULTS: The maximum-tolerated dose was 0.4 mCi/kg IDEC-Y2B8 (0.3 mCi/kg for patients with baseline platelet counts 100 to 149,000/μL). The overall response rate for the intent-to-treat population (n = 51) was 67% (26% complete response [CR]; 41% partial response [PR]); for low-grade disease (n = 34), 82% (26% CR; 56% PR); for intermediate-grade disease (n = 14), 43%; and for mantle-cell disease (n = 3), 0%. Responses occurred in patients with bulky disease (≥ 7 cm; 41%) and splenomegaly (50%). Kaplan-Meier estimate of time to disease progression in responders and duration of response is 12.9+ months and 11.7+ months, respectively. Adverse events were primarily hematologic and correlated with baseline extent of marrow involvement with NHL and baseline platelet count. One patient (2%) developed an anti-antibody response (human antichimeric antibody/human antimouse antibody).CONCLUSION: These phase I/II data demonstrate that IDEC-Y2B8 radioimmunotherapy is a safe and effective alternative for outpatient therapy of patients with relapsed or refractory NHL. A phase III study is ongoing.
