Abstract: Abstract 3567 Autologous transplantation significantly improves the progression free survival (PFS) and overall survival (OS) of patients with relapsed or resistant follicular (rFL) lymphoma compared with chemotherapy alone (Schouten H, et al. J Clin Oncol 2003;21:3918–27). Small phase II trials suggest, that rituximab (R) given peritransplant further improves survival outcome. Whilst the role of maintenance R post chemotherapy in FL is established, the benefit and safety of maintenance R following autologous transplant is unknown. In this randomised prospective study the efficacy and safety of R as in vivo purging pretransplant and as maintenance treatment immediately post transplant was assessed. From Oct 1999 to Apr 2006, 280 of a planned 420 R naïve patients with rFL in first (n=16), second (n= 222) or third remission (n=41) who achieved either a complete remission (n=83) or a very good partial remission (n=196) to induction chemotherapy, with limited bone marrow infiltration ( 〈 25% B-lymphocytes) underwent a single randomisation in a 2 × 2 design to R purging 375 mg/m2 weekly × 4 (RP) before high-dose therapy with BEAM conditioning (HDC) and maintenance R 375 mg/m2 every 3 months for 2 years (RM). The primary endpoint of the study was PFS. All analysis is by intention to treat. The median age was 51 years (range: 26–70), and baseline characteristics were well balanced between groups. On average patients were 44.1 (range 3.4–463.8) months from diagnosis with 79.3% having 2 lines of therapy and 15% three lines of prior therapy. Patients were equally distributed between low, intermediate and high FLIPI scores. Pretransplant 70% of patients were in PR and 30% in CR. Fifty seven patients failed to mobilise peripheral blood stem cells. Nineteen patients withdrew, 5 due to toxicity, 9 were ineligible. In the 196 (70%) patients transplanted, neutrophil engraftment 〉 0.5 × 109 /L was prompt, median 14.3 days (range 10–115) and platelets 〉 50 × 109/L,median 25.1 days (range 9–190). Time to engraftment and early or late toxicities did not differ significantly between the groups apart from a lower neutrophil count at 3 months in patients on maintenance. No graft failures or late neutropenia was reported. Transplant related mortality was 0.5%. Only 3 infection related deaths have been reported post 100 days. Two hundred and seventeen patients are alive on continued follow-up. Median follow-up is 6.4 years. PFS at 5 years was 62.9% for patients receiving RP + RM versus 37.6 % for patients receiving no R (logrank PFS; p=0.004; HR 0.76, 95%CI: 0.66 – 0.93). OS at 5 years was 79.5% % versus 78.4 % for patient receiving RP + RM versus no R (logrank PFS; p 〉 0.1). Multivariate analysis was not able to define a high or low risk patient group. R in vivo purging and maintenance results in superior PFS compared to no R. R does not adversely affect peripheral blood stem cell harvesting or engraftment and maintenance R post transplant is safe. The impressive OS suggests that relapsed FL patients can be effectively salvaged post R purging and maintenance.

Abstract: The objective of this randomized trial was to assess the efficacy and safety of rituximab as in vivo purging before transplantation and as maintenance treatment immediately after high-dose chemotherapy and autologous stem-cell transplantation (HDC-ASCT) in patients with relapsed follicular lymphoma (FL). Patients and Methods Patients with relapsed FL who achieved either complete or very good partial remission with salvage chemotherapy were randomly assigned using a factorial design to rituximab purging (P+; 375 mg/m 2 once per week for 4 weeks) or observation (NP) before HDC-ASCT and to maintenance rituximab (M+; 375 mg/m 2 once every 2 months for four infusions) or observation (NM). Results From October 1999 to April 2006, 280 patients were enrolled. The median age was 51 years (range, 26 to 70 years), and baseline characteristics were well balanced between groups. On average, patients were 44 months (range, 3 to 464 months) from diagnosis, with 79% having received two lines and 15% three lines of prior therapy. Median follow-up was 8.3 years. In contrast to purging, 10-year progression-free survival (PFS) was 48% for P+ and 42% for NP groups (hazard ratio [HR], 0.80; 95% CI, 0.58 to 1.11; P = .18); maintenance had a significant effect on PFS (10-year PFS, 54% for M+ and 37% for NM; HR, 0.66; 95% CI, 0.47 to 0.91; P = .012). Overall survival (OS) was not improved by either rituximab purging or maintenance. Conclusion Rituximab maintenance after HDC-ASCT is safe and significantly prolongs PFS but not OS in patients undergoing transplantation for relapsed FL. Pretransplantation rituximab in vivo purging, even in rituximab-naive patients, failed to improve PFS or OS.

Abstract: Introduction: In spite of improvements in treatment of mantle cell lymphoma (MCL), this is still considered an incurable lymphoma entity, and the majority of patients eventually relapse. Ibrutinib is a very active agent in MCL, but in vitro has been shown to partially antagonize the activity of rituximab, by suppression of NK cell activity and subsequent ADCC. Lenalidomide, on the other hand, improves rituximab-induced ADCC. In this multi-centre open-label phase II trial, we evaluated safety and efficacy of this triplet combination in patients with relapsed or refractory MCL. Methods: Patients with MCL, relapsing after or refractory to at least one rituximab-containing chemotherapy regimen, WHO PS 0-3, and measurable disease were eligible. The primary endpoint was maximal overall response rate (ORR) measured with CT and PET/CT. Minimal residual disease (MRD) monitoring by PCR was performed during follow-up, according to EuroMRD criteria. Ion Torrent sequencing of the most frequently mutated genes in MCL was performed on frozen tumor cells from bone marrow at time of relapse. Health-related quality of life was assessed by the EORTC-QLQ C30 questionnaire before and during treatment. Treatment schedule: Induction phase: Up to twelve 28-day cycles with: Lenalidomide 15 mg p o daily, days 1-21, Ibrutinib 560 mg p o days 1-28, Rituximab 375 mg/m2 i v day 1 in cycle 1, then 1400 mg s c (or 375 mg/m2i v) days 8, 15 and 22 in cycle 1, then day 1 in cycles 3, 5, 7, 9 and 11. Maintenance phase: For patients in CR, PR or SD, not in need of other treatment, given until progression, cycle duration 56 days. Ibrutinib: 560 mg p o days 1-56, 2. Rituximab 1400 mg s c (or 375 mg/m2i v) day 1 of each cycle. Results: Accrual of 50 pts was completed in June 2016, at 10 centres in Sweden, Norway, Denmark and Finland. The median age was 69.5 years, with a median MIPI score of 6.2. Patients had received a median of two previous regimens, four had progressed after single agent ibrutinib, and three had received prior allo-SCT. A TP53 mutation was detected in 11 of 49 evaluable cases (22%), 8 cases were of blastoid/pleomorphic histology, and 22 of 40 evaluable cases had a Ki67 & gt;30%. Treatment emergent-AEs of any grade in ≥20% of patients were rash (24%) and fatigue (20%). Five pts (10%) experienced rash grade 3, mainly during cycle 1. Hematological toxicity was generally of low grade, apart from grade 3-4 neutropenia in 5 patients. One patient died due to possible treatment-related toxicity (septic shock). In total, 27 patients achieved CR (54%) and 10 PR (20%). Among evaluable patients with a TP53 mutation, blastoid/pleomorphic histology or Ki67 & gt;30%, the CR rates were 7/11 (64%), 15/8 (62%) and 11/22 (50%), respectively. After a median follow-up of 40 months, the median PFS is 18 months (95% CI 6.5-28), and median OS 47 months (95% CI 30-64). Patients with a detectable TP53 mutation at relapse (n=11) had a median PFS of 13 months (95% CI 4.2-21), whereas pts without a TP53 mutation had a median PFS of 34 months (95% CI 8.3-60). Of the 28 patients evaluable for MRD at 6 months, 15/27 (56%) patients achieved molecular remission in blood and 12/28 (43%) in bone marrow. After 12 months, MRD-negativity in BM was 68% (13/19). Out of 4 patients with TP53-mutated MCL, 2 were MRD-negative in BM after 12 months, as well as 2 out of 4 patients with blastoid/pleomorphic histology. By self-reported HRQOL, a lower level of emotional functioning (EF), as well as a higher level of pain (PA) at baseline, was associated with inferior PFS. In addition, low EF was associated with inferior OS. By a Cox regression multivariable analysis, including MIPI, TP53, histology, Ki67, EF and PA, only MIPI was prognostic for PFS or OS with this regimen. Conclusions: The combination of ibrutinib, lenalidomide and rituximab has been shown to be an active and well tolerated regimen in this cohort of high risk R/R MCL, associated with a high rate of molecular remission. The activity in TP53 mutated MCL is lower than in unmutated disease, but this regimen may still serve as an option for a bridge to an allogeneic transplantation or CAR-T therapy in this category of patients.

Abstract: In recent decades, the prognosis of Mantle Cell Lymphoma ( MCL ) has been significantly improved by intensified first‐line regimens containing cytarabine, rituximab and consolidation with high‐dose‐therapy and autologous stem cell transplantation. One such strategy is the Nordic MCL 2 regimen, developed by the Nordic Lymphoma Group. We here present the 15‐year updated results of the Nordic MCL 2 study after a median follow‐up of 11·4 years: For all patients on an intent‐to‐treat basis, the median overall and progression‐free survival was 12·7 and 8·5 years, respectively. The MCL International Prognostic Index ( MIPI ), biological MIPI , including Ki67 expression ( MIPI ‐B) and the MIPI ‐B including mIR ‐18b expression ( MIPI ‐B‐miR), in particular, significantly divided patients into distinct risk groups. Despite very long response durations of the low and intermediate risk groups, we observed a continuous pattern of relapse and the survival curves never reached a plateau. In conclusion, despite half of the patients being still alive and 40% in first remission after more than 12 years, we still see an excess disease‐related mortality, even among patients experiencing long remissions. Even though we consider the Nordic regimen as a very good choice of regimen, we recommend inclusion in prospective studies to explore the benefit of novel agents in the frontline treatment of MCL .

Abstract: In an update of the randomized, open-label, phase III European Mantle Cell Lymphoma (MCL) Elderly trial (ClinicalTrials.gov identifier: NCT00209209 ), published in 2012, we aimed to confirm results on long-term outcome focusing on efficacy and safety of long-term use of rituximab maintenance. PATIENTS AND METHODS Five hundred sixty patients with newly diagnosed MCL underwent a first random assignment between rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) and rituximab, fludarabine, and cyclophosphamide (R-FC) induction, followed by a second random assignment in 316 responders between rituximab and interferon alfa maintenance, to be continued until progression. We compared progression-free survival from the second randomization and overall survival (OS) from the first or second randomizations. RESULTS After a median follow-up time of 7.6 years, the previously described difference in OS between the induction arms persisted (median, 6.4 years after R-CHOP [n = 280] v 3.9 years after R-FC [n = 280] ; P = .0054). Patients responding to R-CHOP had median progression-free survival and OS times of 5.4 and 9.8 years, respectively, when randomly assigned to rituximab (n = 87), compared with 1.9 years ( P 〈 .001) and 7.1 years ( P = .0026), respectively, when randomly assigned to interferon alfa (n = 97). In 58% and 32% of patients treated with R-CHOP, rituximab maintenance was still ongoing 2 and 5 years from start of maintenance, respectively. After R-FC, rituximab maintenance was associated with an unexpectedly high cumulative incidence of death in remission (22% at 5 years). Toxicity of rituximab maintenance was low after R-CHOP (grade 3-4 leukopenia or infection 〈 5%) but more prominent in patients on rituximab maintenance after R-FC, in whom grade 3-4 leukopenia (up to 40%) and infections were frequent (up to 15%). CONCLUSION The excellent results of R-CHOP followed by rituximab maintenance until progression for older patients with MCL persisted in a mature follow-up. Prolongation of rituximab maintenance beyond 2 years is effective and safe.

Abstract: Background: In early studies of venetoclax (ven) in CLL, severe tumor lysis syndromes (TLS) were observed leading to the implementation of multiple safety measures including a 5-week ramp up schedule. Since then, studies have consistently reported low rates of TLS in ven-treated patients (pts), most likely as a result of strict prophylactic and laboratory monitoring measures. Various lead-in regimens prior to the administration of ven were shown to be feasible and effective in reducing the risk of TLS in pts with CLL. However, no comparison of different pretreatment regimens has been performed so far in a prospective randomized trial. Using the set-up of the GAIA trial, we compared TLS incidence and formal TLS risk reduction between 3 different ven-based combinations. Methods: The phase 3 GAIA (CLL13) trial compared 3 different time-limited ven-based combinations against standard chemoimmunotherapy (CIT) in fit, treatment-naïve pts with CLL. Pts were randomized to receive CIT (FCR in pts ≤65 years; BR in pts & gt;65 years), ven and rituximab (RVe), ven and obinutuzumab (GVe), or ven, obinutuzumab and ibrutinib (GIVe). In RVe, GVe and GIVe, ven was added at cycle 1 day 22 (ramp up day 1) after a 21-day pretreatment with rituximab (1 dose), obinutuzumab (3 doses) or obinutuzumab (3 doses) plus ibrutinib (continuous) (Figure 1A). The safety population (i.e. all pts who received study treatment) of the ven-containing arms was used for this analysis. TLS was reported according to Cairo-Bishop criteria (Cairo M, Bishop M. Br J Haematol. 2004). For TLS risk evaluation, the most recent available CT/MRI and absolute lymphocyte count (ALC) were used. TLS risk was evaluated at baseline and at ramp up day 1, before the first dose of ven. The patients were categorized retrospectively according to the following TLS risk categories: high (any lymph node [LN] with largest diameter ≥10 cm or any LN with largest diameter ≥5 cm and ALC ≥25 G/L), intermediate (any LN ≥5 cm to & lt;10 cm or ALC ≥25 G/L), low (all LN & lt;5 cm and ALC & lt;25 G/L). Results: The safety population of all ven-containing arms comprised of 696 pts (RVe: 237, GVe: 228, GIVe: 231). Baseline TLS risk was high in 22%, 23% and 19% of pts in the RVe, GVe and GIVe arm, intermediate in 62%, 65%, 67% and low in 10.5%, 14.7% and 12.4% of pts, respectively. After the first 21 days of treatment (i.e. at ramp up day 1), the fraction of pts with a reduction in TLS risk varied between the treatment arms with 31.7% (RVe), 71.4% (GVe) and 47.3% (GIVe) of pts decreasing by at least one TLS risk category (Figure 1B). With regard to TLS risk reduction, GVe was superior to RVe (p & lt;0.001) and GIVe (p & lt;0.001) while GIVe was superior to RVe (p=0.001)). At ramp up day 1, 2 patients (1.0%) in the GVe arm versus 60 patients (29.6%) in the GIVe arm had an ALC ≥25 G/L, likely as a correlate of ibrutinib-associated redistribution of lymphocytes to the peripheral blood, readily explaining part of the difference in TLS risk reduction between GVe and GIVe. In total, 36, 30 and 19 cases of TLS occurred in 29 (12.2%), 26 (11.4%) and 19 (8.2%) pts in the RVe, GVe and GIVe arm. The majority of TLS cases were categorized as CTC grade 3 (28 [RVe], 19 [GVe] , 12 [GIVe]), only few CT C grade 4 TLS were reported (1 [RVe], 2 [GVe] , 3 [GIVe]). There were no cases of fatal TLS and no pts requiring dialysis due to TLS. In the obinutuzumab arms the majority of TLS cases occurred before ramp up day 1 (GVe: 76.7%, GIVe: 68.4%), i.e. before any venetoclax intake, in contrast 80.6% of TLS cases in the RVe arm were reported during ven ramp up (Figure 2). While there was no significant difference in the cumulative TLS incidence between the treatment arms (p=0.334), there was an increase in TLS occurring after ramp up day 1 in the RVe arm compared to GVe (p & lt;0.001) and GIVe (p=0.002). Conclusions: This analysis represents the first comparison of the formal TLS risk reduction and actual TLS incidence of different ven-based combinations in a randomized trial. GVe led to the highest TLS risk reduction, while the lowest number of TLS cases occurred in the GIVe arm. Most TLS cases in the GVe and GIVe arms occurred before the start of ven. RVe was least effective in reducing TLS risk and in contrast to the obinutuzumab-containing arms, the vast majority of TLS cases was reported during the ven ramp up. The relatively high incidence of TLS in comparison to other trials might partly be a consequence of using different reporting criteria (Cairo-Bishop vs Howard criteria). No fatal TLS occurred in any of the treatment arms. Figure 1 Figure 1.

Abstract: Background: Minimal residual disease monitoring has been shown to be of relevance in mantle cell lymphoma (MCL) to evaluate quality of remission and predict clinical relapse. The main objectives of the present study were to determine the value of minimal residual disease (MRD) monitoring to guide pre-emptive treatment with rituximab, and to predict clinical relapse in MCL following autologous stem cell transplantation (ASCT) in two prospective trials (MCL2 and MCL3) with long-term follow-up conducted by the Nordic Lymphoma Group. Methods: Patients treated in the two studies received a total of 6 alternating cycles with R-CHOP and R-Ara-C followed by a peripheral blood stem cell harvest and high-dose therapy with ASCT. Additionally, responding patients not in CR before ASCT in the MCL3 trial received yttium-90 ibritumomab tiuxetan (0.4 mCi/kg) as intensification one week prior to the standard conditioning with BEAM/C. Staging included physical examination, blood tests, computed tomography (CT) scans and bone marrow (BM) aspiration and biopsy. Clinical and molecular response evaluation was repeated 2-3 months and 6 months after transplant, and then every 6 months until relapse or 5 years follow-up. A combined standard nested and quantitative real-time PCR assay was used to estimate MRD involvement in consecutive post-transplant BM/PB samples. Molecular relapse after ASCT was defined as; 1. Conversion from standard nested PCR negative to standard nested PCR positive, or 2. For patients who were MRD positive post-ASCT, a significant ( 〉 5 fold) increase of the real time quantitative PCR detectable MRD level in two consecutive BM samples. Patients in clinical remission who developed a molecular relapse in both studies received 4 weekly doses of rituximab (375 mg/m2). This treatment could be repeated in case of recurrent molecular relapses. Results: An MRD marker for Bcl-1 or IgH rearrangement was obtained for 94 out of 160 patients (59%) recruited in the Nordic MCL2 trial, and for 121 out of 160 (76%) in the consecutive MCL3 trial. 183 patients, who had completed induction therapy and autologous stem cell transplantation (ASCT) in the two studies and where a PCR marker in blood or bone marrow was obtained, were included in the current analysis. Median follow-up from inclusion was 8.5 years among survivors. Patients who were MRD negative post-ASCT had significantly longer relapse-free survival (RFS) and overall survival (OS) compared to those who were MRD positive (P 〈 0.001). Eighty-six patients remained in continuous molecular remission. Of those, 73% also remained in clinical remission after 10 years. For all patients, median time from ASCT to molecular relapse was 55 months and with no signs of a plateau on the curve (Figure 1). Fifty-eight patients with MRD relapse received pre-emptive treatment with 4 weekly doses of rituximab (375 mg/m2) on one or more occasions. Conversion back to MRD negative state was achieved in the majority (82%) of cases after rituximab treatment. Median time from molecular relapse to clinical relapse in patients who received pre-emptive rituximab was 55 months (Figure 2). In a multivariate analysis, significant predictors for molecular relapse were MIPI high risk category at diagnosis (HR 1.91, 95% CI 1.37-2.66, P=0,0001) and detection of MRD prior to ASCT (HR 2.47, 95% CI 1.49-4.09, P=0.0005). Late MRD relapses continued to occur 5-10 years after ASCT even in lower risk groups. Conclusion: We observed a continuous pattern of MRD relapses that did not subside even after 5-10 years and included all risk groups. Hence, it is fair to consider MCL as a chronic incurable lymphoma entity and novel approaches will be necessary to change the natural course of this disease. Detection of MRD was shown to be a predictor for clinical relapse and inferior survival. Additionally, the data strongly suggests that pre-emptive rituximab treatment delayed clinical relapse in MCL. We recommend MRD monitoring post-ASCT in MCL as a useful approach to select the MRD positive patients for novel strategies in future trials and as an alternative to maintenance therapy for all patients.

Abstract: Introduction: In spite of improvements in treatment of mantle cell lymphoma (MCL) over the last 10-15 years, this is still considered an incurable lymphoma entity, and the majority of patients eventually relapse. Ibrutinib is a very active agent in MCL, with an overall response rate (ORR) of 68% as a single agent in the relapse situation. In vitro, ibrutinib has been shown to partially antagonize the activity of rituximab, by suppression of NK cell activity and subsequent ADCC. Lenalidomide, on the other hand, improves rituximab-induced ADCC. In this multi-centre open-label phase II trial, we evaluated safety and efficacy of this triplet combination in patients with relapsed or refractory MCL. A phase I trial with this combination has been performed in 22 patients with untreated follicular lymphoma (Alliance 051103). In this trial, rash was the most common adverse event (AE), occuring in 73% of pts, with grade 3 rash in 32%. Methods: Eligibility criteria were: patients with MCL, relapsing after or refractory to at least one rituximab-containing chemotherapy regimen, WHO PS 0-3, and measurable disease. The primary endpoint was maximal overall response rate (ORR) measured with CT and PET/CT. Minimal residual disease (MRD) monitoring by PCR was performed during follow-up, according to EuroMRD criteria. Ion Torrent sequencing was performed on frozen tumor cells from bone marrow at time of relapse, including the following genes: ATM, CCND1, TP53, KMT2D, NOTCH1, NOTCH2, WHSC1 and BIRC3. Treatment schedule: Induction phase: Up to twelve 28-day cycles with: Lenalidomide 15 mg p o daily, days 1-21, Ibrutinib 560 mg p o days 1-28, Rituximab 375 mg/m2 i v day 1 in cycle 1, then 1400 mg s c (or 375 mg/m2i v) days 8, 15 and 22 in cycle 1, then day 1 in cycles 3, 5, 7, 9 and 11. Maintenance phase: For patients in CR, PR or SD, not in need of other treatment. Given until progression, cycle duration 56 days. Ibrutinib: 560 mg p o days 1-56, 2. Rituximab 1400 mg s c (or 375 mg/m2i v) day 1 of each cycle. Results: Accrual of 50 pts was completed in 12 months, June 2016, at 10 centres in Sweden, Norway, Denmark and Finland. The median age was 69.5 years, with a median MIPI score of 6.2. Patients had received a median of two previous regimens, four had progressed after single agent ibrutinib, and three had received prior allo-SCT. In total, 17/50 pts have discontinued treatment (n=9 due to PD, n=4 due to AE, n=2 withdrew consent, n=1 proceeded to alloSCT and n=1 due to other cause). Treatment emergent-AEs of any grade in ≥20% of patients were rash (24%) and fatigue (20%). Five pts (10%) experienced rash grade 3, mainly during cycle 1. Hematological toxicity was generally of low grade, apart from grade 3-4 neutropenia in 5 patients. One patient died due to possible treatment-related toxicity (septic shock). One event of laboratory tumor lysis syndrome was reported, and two events of atrial fibrillation, without reduction or discontinuation of ibrutinib. With a median follow up time of 7 months, 29 patients were evaluable for efficacy as of July 14, 2016. The ORR to date is 83% with 12 patients achieving CR (41%) and 12 PR (41%). Median duration of response and PFS has not been reached. One of three evaluable patients with progression on single agent ibrutinib responded with a PR, with ongoing response at 9 months. Of the 13 patients evaluable for MRD at 6 months, 7/12 patients have achieved molecular remission in blood and 7/13 in bone marrow. Conclusions: So far, the combination of ibrutinib, lenalidomide and rituximab has been shown to be an active and well tolerated regimen in patients with R/R MCL, associated with molecular remission. Cutaneous toxicity was manageable, in contrast to what has been reported with a similar combination in untreated patients with follicular lymphoma. Up-dated results will be presented at the annual meeting, including data on mutational profile as biomarker for efficacy. This trial was registered at http://clinicaltrials.gov as NCT02460276.

Abstract: Background: Mantle cell lymphoma (MCL) is a rare, often aggressive type of B-cell lymphoma with poor survival and no cure. Cancer and cancer treatment has a negative impact on health-related quality of life (HRQOL) both during active disease and in the long term, and improvement of HRQOL may be one of the most important objectives of cancer therapy. In addition, baseline HRQOL has in other lymphoma populations been shown to be predictive of outcome. Hitherto, there are only few reports on HRQOL in MCL. The primary aim of this study was to explore HRQOL before, during and after chemotherapy in an elderly population with MCL. Secondary aims were to identify predictors for HRQOL, information that can be used for improvement in rehabilitation. Methods: The cohort consisted of patients included in the multicenter open-label phase Ib-II NLG-MCL4 trial (LENA-BERIT), designed to evaluate the addition of lenalidomide (LEN) to rituximab-bendamustine (R-B) as first-line treatment in elderly patients ( & gt;65 years) with MCL. The treatment with R-B stopped after six months, LEN continued for six more months. HRQOL was assessed by the EORTC QLQ-C30 questionnaire pre-treatment, and after 6, 12 and 24 months post study inclusion. For the functional scales and the global quality of life scale a higher score represents a better level of functioning. For the symtom scales and single items, a higher score corresponds to a higher level of symtoms. Patient scores were compared to scores from a reference population sample at baseline. Survival was analysed by Kaplan-Meier estimates, and cox regression multivariate analysis was used to assess survival with adjustments for prognostic factors, age, sex and more. Results: Fifty-one patients were enrolled, 1 patient was excluded based on screen failure. Median age was 71 years (range 62-84), 37 were men (73%). Stratified according to Mantle Cell Lymphoma International Prognostic Index (MIPI), 5 (10%) were low-risk, 18 (38%) intermediate and 26 (52%) high-risk. Follow-up time for living patients were 52 months, and for deceased patients 27 months. Median overall survival time were 52 months. The proportion of patients reporting HRQOL data was at baseline; 48 (96%), after 6 months; 33 (83%), after 12 months; 27 (89%), and after 24 months; 12 (75%). During the first six months of treatment, several functional scores deteriorated, and after 12 months it had stabilised at baseline level or better. The global health status (QoL) improved at 12 months after diagnosis, but then dropped to baseline levels after 2 years. Before treatment, patients exhibited levels of the symptom scores, comparable to the reference population. Six months after start of therapy, the scores for pain, dyspnoea and insomnia were improved, while appetite loss and diarrhoea were impaired. After 12 months, the symptom scales improved to a level superior compared both to baseline and the reference population. The population was divided into two groups, with the median as cut-off values. In the multivariate analysis, including MIPI, gender and the presence of TP53 mutation, impaired pre-treatment physical function, role function and elevated pain score were independent prognostic markers for overall survival. Role function and pain were also independent prognostic markers for progression free survival. Conclusion: In this population of elderly patients with MCL, pre-treatment HRQOL was similar to the reference population. During treatment, HRQOL deteriorated, but reverted to the same level as the reference population after treatment. Pre-treatment physical and role function and pain were independent factors associated with overall survival. These novel findings may be used to design support during treatment and improve rehabilitation.
