  • Lenalidomide-bendamustine-rituximab in untreated mantle cell lymphoma > 65 years, the Nordic Lymphoma Group phase I+II trial NLG-MCL4
  • 2016
  • Ingår i: Blood. - : American Society of Hematology. - 1528-0020 .- 0006-4971. ; 128:14, s. 1814-1820

    • For elderly patients with mantle cell lymphoma (MCL), there is no defined standard therapy. In this multicenter open-label phase I/II trial we evaluated the addition of lenalidomide (LEN) to rituximab-bendamustine (R-B) as first-line treatment to elderly MCL patients. Patients >65 years with untreated MCL, stage II-IV were eligible for inclusion. Primary endpoints were maximally tolerable dose (MTD) of LEN, and progression-free survival (PFS). Patients received six cycles q4w of L-B-R (L D1-14, B 90 mg/m(2) iv D1-2 and R 375 mg/m(2) iv D1) followed by single LEN (D1-21, q4w, cycles 7-13). 51 patients (median age 71 years) were enrolled 2009-2013. In phase I, the MTD of LEN was defined as 10 mg in cycles 2-6, and omitted in cycle 1. After six cycles, the complete remission rate (CRR) was 64% and 36% were MRD negative. At a median follow-up time of 31 months, median PFS was 42 months and 3 year overall survival was 73%. Infection was the most common non-hematological grade 3-5 event and occurred in 21 (42%) patients. Opportunistic infections occurred in three patients; 2 PCP and 1 CMV retinitis. Second primary malignancies (SPM) were observed in eight patients (16%). LEN could safely be combined with R-B, when added from the second cycle in patients with MCL, and was associated with a high rate of CR and molecular remission. However, we observed a high degree of severe infections and an unexpected high number of SPMs which may limit its use. http://clinicaltrials.gov: NCT00963534.

  • The Mantle Cell Lymphoma International Prognostic Index (MIPI) is superior to the International Prognostic Index (IPI) in predicting survival following intensive first-line immunochemotherapy and autologous stem cell transplantation (ASCT)
  • 2010
  • Ingår i: Blood. - : American Society of Hematology. - 0006-4971 .- 1528-0020. ; 115:8, s. 1530-1533
  • Tidskriftsartikel (refereegranskat)abstract
    • Mantle cell lymphoma (MCL) has a heterogeneous clinical course. The recently proposed Mantle Cell Lymphoma International Prognostic Index (MIPI) predicted the survival of MCL better than the International Prognostic Index in MCL patients treated with conventional chemotherapy, but its validity in MCL treated with more intensive immunochemotherapy has been questioned. Applied here to 158 patients of the Nordic MCL2 trial of first-line intensive immunochemotherapy followed by high-dose chemotherapy and autologous stem cell transplantation, the MIPI and the simplified MIPI (s-MIPI) predicted survival significantly better (P < .001) than the International Prognostic Index (P > .004). Both the MIPI and the s-MIPI mainly identified 2 risk groups, low and intermediate versus high risk, with the more easily applied s-MIPI being just as powerful as the MIPI. The MIPI(B) (biological), incorporating Ki-67 expression, identified almost half of the patients as high risk. We suggest that also a simplified MIPI(B) is feasible.

  • Nordic MCL-3 study : 90Y-ibritumomab-tiuxetan added to BEAM/C in non-CR patients before transplant in mantle cell lymphoma
  • 2014
  • Ingår i: Blood. - : American Society of Hematology. - 0006-4971 .- 1528-0020. ; 123:19, s. 2953-2959
  • Tidskriftsartikel (refereegranskat)abstract
    • The main objective of the MCL3 study was to improve outcome for patients not in CR before transplant by adding (90)Y-ibritumomab-tiuxetan (Zevalin) to the high-dose regimen. 160 consecutive, untreated stage II-IV MCL patients < 66 years received rituximab (R)- maxi-CHOP alternating with R-high-dose Ara-C (6 cycles total), followed by high-dose BEAM or BEAC and autologous stem cell transplantation 2005-2009. Zevalin (0.4 mCi/kg) was given to responders in only CRu/PR prior to high-dose therapy. The overall response rate (ORR) pre-transplant was 97%. After a median follow-up of 4.4 years the outcome did not differ from that of the historic control, the MCL2 trial with the same treatment except for Zevalin. Overall (OS), event free (EFS), and progression-free survival (PFS) at 4 years were 78, 62 and 71%, respectively. For patients in CRu/PR before transplant who received Zevalin duration of response was shorter than in the CR group. Inferior PFS, EFS- and OS were predicted by PET-positivity pre-transplant and detectable minimal residual disease (MRD) before and after transplant. In conclusion, a positive PET prior to transplant and MRD are strong predictors of outcome. Late intensification with Zevalin may be too late to improve the outcome of patients not in CR before transplant.

  • SOX11 and TP53 add prognostic information to MIPI in a homogenously treated cohort of mantle cell lymphoma : a Nordic Lymphoma Group study
  • 2014
  • Ingår i: British Journal of Haematology. - : Wiley. - 0007-1048 .- 1365-2141. ; 166:1, s. 98-108
  • Tidskriftsartikel (refereegranskat)abstract
    • Mantle cell lymphoma (MCL) is an aggressive B cell lymphoma, where survival has been remarkably improved by use of protocols including high dose cytarabine, rituximab and autologous stem cell transplantation, such as the Nordic MCL2/3 protocols. In 2008, a MCL international prognostic index (MIPI) was created to enable stratification of the clinical diverse MCL patients into three risk groups. So far, use of the MIPI in clinical routine has been limited, as it has been shown that it inadequately separates low and intermediate risk group patients. To improve outcome and minimize treatment-related morbidity, additional parameters need to be evaluated to enable risk-adapted treatment selection. We have investigated the individual prognostic role of the MIPI and molecular markers including SOX11, TP53 (p53), MKI67 (Ki-67) and CCND1 (cyclin D1). Furthermore, we explored the possibility of creating an improved prognostic tool by combining the MIPI with information on molecular markers. SOX11 was shown to significantly add prognostic information to the MIPI, but in multivariate analysis TP53 was the only significant independent molecular marker. Based on these findings, we propose that TP53 and SOX11 should routinely be assessed and that a combined TP53/MIPI score may be used to guide treatment decisions.

  • Expression patterns and prognostic potential of circular RNAs in mantle cell lymphoma : a study of younger patients from the MCL2 and MCL3 clinical trials
  • 2022
  • Ingår i: Leukemia. - : Springer Science and Business Media LLC. - 0887-6924 .- 1476-5551. ; 36:1, s. 177-188
  • Tidskriftsartikel (refereegranskat)abstract
    • Mantle cell lymphoma (MCL) is characterized by marked differences in outcome, emphasizing the need for strong prognostic biomarkers. Here, we explore expression patterns and prognostic relevance of circular RNAs (circRNAs), a group of endogenous non-coding RNA molecules, in MCL. We profiled the circRNA expression landscape using RNA-sequencing and explored the prognostic potential of 40 abundant circRNAs in samples from the Nordic MCL2 and MCL3 clinical trials, using NanoString nCounter Technology. We report a circRNA-based signature (circSCORE) developed in the training cohort MCL2 that is highly predictive of time to progression (TTP) and lymphoma-specific survival (LSS). The dismal outcome observed in the large proportion of patients assigned to the circSCORE high-risk group was confirmed in the independent validation cohort MCL3, both in terms of TTP (HR 3.0; P = 0.0004) and LSS (HR 3.6; P = 0.001). In Cox multiple regression analysis incorporating MIPI, Ki67 index, blastoid morphology and presence of TP53 mutations, circSCORE retained prognostic significance for TTP (HR 3.2; P = 0.01) and LSS (HR 4.6; P = 0.01). In conclusion, circRNAs are promising prognostic biomarkers in MCL and circSCORE improves identification of high-risk disease among younger patients treated with cytarabine-containing chemoimmunotherapy and autologous stem cell transplant.

  • Clonal hematopoiesis evolves from pretreatment clones and stabilizes after end of chemotherapy in patients with MCL
  • 2020
  • Ingår i: Blood. - : American Society of Hematology. - 1528-0020 .- 0006-4971. ; 135:22, s. 2000-2004
  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • Eskelund et al examined clonal hematopoiesis (CH) in a cohort of patients with mantle cell lymphoma (MCL) treated with first-line chemotherapy and autologous stem cell transplantation. In young, good-risk MCL patients, CH after first-line therapy arises almost entirely from preexisting clones, stabilizes after a period of expansion posttransplantation, and does not negatively impact survival.

  • Pre-treatment health-related quality of life parameters have prognostic impact in patients >65 years with newly diagnosed mantle cell lymphoma : The Nordic Lymphoma Group MCL4 (LENA-BERIT) experience
  • 2022
  • Ingår i: Hematological Oncology. - : Wiley. - 0278-0232 .- 1099-1069. ; 40:1, s. 23-31
  • Tidskriftsartikel (refereegranskat)abstract
    • 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 is a crucial objective of cancer therapy in older patients and no curative intent. Baseline HRQOL has in other lymphoma populations been shown to be predictive of outcome. Here, we explored HRQOL, and its association with survival, by the EORTC QLQ-C30 questionnaire, before, during and after chemotherapy in a patient cohort with MCL, treated within the NLG-MCL4 trial, designed to evaluate the addition of lenalidomide (LEN) to rituximab-bendamustine (R-B) as first-line treatment. Fifty-one patients were enrolled, median age was 71 years (range 62–84), 37 were men (73%). Pre-treatment HRQOL was similar to scores from the reference population with healthy individuals. During treatment, HRQOL deteriorated, but reverted to the same level as the reference population after treatment. There was a correlation between physical function (p = 0.001) and role function (p = 0.006) at baseline and WHO performance status, but not with other clinical or genetic prognostic factors. None of the baseline factors were predictive for treatment related to HRQOL in this cohort. Pre-treatment physical (p = 0.011) and role function (p = 0.032) were independent factors associated with overall survival, and physical function (p = 0.002) was also associated with progression free survival. These findings may possibly be used to design support during treatment and improve rehabilitation. Further investigations are needed for assessment of long-term HRQOL.

  • Immune-related protein signature in serum stratify relapsed mantle cell lymphoma patients based on risk
  • 2020
  • Ingår i: BMC Cancer. - : Springer Science and Business Media LLC. - 1471-2407. ; 20:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Response to modern treatment strategies, which combine cytotoxic compounds with immune stimulatory agents and targeted treatment is highly variable among MCL patients. Thus, providing prognostic and predictive markers for risk adapted therapy is warranted and molecular information that can help in patient stratification is a necessity. In relapsed MCL, biopsies are rarely available and molecular information from tumor tissue is often lacking. Today, the main tool to access risk is the MCL international prognostic index (MIPI), which does not include detailed biological information of relevance for different treatment options. To enable continuous monitoring of patients, non-invasive companion diagnostic tools are needed which can further reduce cost and patient distress and enable efficient measurements of biological markers. Methods: We have assessed if serum-based protein profiling can identify immune related proteins that stratify relapsed MCL patients based on risk. Overall, 371 scFv targeting 158 proteins were assessed using an antibody microarray platform. We profiled patients (n = 44) who had been treated within the MCL6-Philemon trial combining targeted and immune-modulatory treatment. Results: The downstream processing led to the identification of the relapsed immune signature (RIS) consisting of 11 proteins with potential to stratify patients with long and short overall survival (OS). Moreover, in this population, MIPI alone failed to separate high, intermediate and low risk patients, but a combined index based on MIPI together with RIS, MIPIris, showed improved performance and significantly stratified all three risk groups based on OS. Conclusions: Our results show that addition of biological parameters to previous prognostic indices improves patient stratification among patients treated with BTK inhibitor triplet combination, particularly, in the identification of an extreme high risk group.

  • Serum proteome modulations upon treatment provides biological insight on response to treatment in relapsed mantle cell lymphoma
  • 2022
  • Ingår i: Cancer Reports. - : Wiley. - 2573-8348. ; 5:7
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The possibility to monitor patient's serum proteome during treatment can provide deepened understanding of the biology associated with response to specific drugs. Non-invasive serum sampling provides an opportunity for sustainable repetitive sampling of patients, which allows for more frequent evaluation of the biological response and enhanced flexibility in treatment selection in contrast to tissue biopsies. Aim: To pin-point biologically relevant changes in pre- and on-treatment serum proteome samples in relapsed mantle cell lymphoma (MCL) patients, leading to insight into mechanisms behind response to treatment in sub-groups of patients. Methods: Pre- and on-treatment serum samples from relapsed MCL patients treated with a triple combination therapy of rituximab, ibrutinib and lenalidomide were available for the study, together with detailed clinicopathological information. A microarray technology targeting 158 serum proteins using 371 antibody-fragments was used to compare the serum proteome at the two time-points. Results: Proteins modulated by the treatment were shown to be associated to a MCL sub-group with ATM/TP53 alterations, which emphasizes the importance of treatment stratification. Absolute values of serum protein levels in on-treatment samples were highly variable and showed no correlation to outcome. To circumvent the challenge of variability in absolute serum protein levels, the velocity of change of individual serum proteins was used to identify proteins associated with clinical response. Increased values of TGF-β1, CD40 and complement component 4 comparing pre- and on-treatment samples were associated with remaining minimal residual disease (MRD) and increased BTK was associated with short progression-free survival (PFS). Conclusion: We show that the genetic sub-type of MCL affects the biological response to treatment in serum and that the change in defined serum proteins reveals the biology associated with clinical response.

  • p53 is associated with high-risk and pinpoints TP53 missense mutations in mantle cell lymphoma
  • 2020
  • Ingår i: British Journal of Haematology. - : Wiley. - 0007-1048 .- 1365-2141. ; 191:5, s. 796-805
  • Tidskriftsartikel (refereegranskat)abstract
    • Survival for patients diagnosed with mantle cell lymphoma (MCL) has improved drastically in recent years. However, patients carrying mutations in tumour protein p53 (TP53) do not benefit from modern chemotherapy-based treatments and have poor prognosis. Thus, there is a clinical need to identify missense mutations through routine analysis to enable patient stratification. Sequencing is not widely implemented in clinical practice for MCL, and immunohistochemistry (IHC) is a feasible alternative to identify high-risk patients. The aim of the present study was to investigate the accuracy of p53 as a tool to identify patients with TP53 missense mutations and the prognostic impact of overexpression and mutations in a Swedish population-based cohort. In total, 317 cases were investigated using IHC and 255 cases were sequenced, enabling analysis of p53 and TP53 status among 137 cases divided over the two-cohort investigated. The accuracy of predicting missense mutations from protein expression was 82%, with sensitivity at 82% and specificity at 100% in paired samples. We further show the impact of p53 expression and TP53 mutations on survival (hazard ratio of 3·1 in univariate analysis for both), and the association to risk factors, such as high MCL International Prognostic Index, blastoid morphology and proliferation, in a population-based setting.
