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.

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.

R-hyper-CVAD versus R-CHOP/cytarabine with high-dose therapy and autologous haematopoietic stem cell support in fit patients with mantle cell lymphoma: 20 years of single-center experience.

Standard of care for untreated mantle cell lymphoma (MCL) is still debated. At the University Hospital Zurich, advanced MCL in physically fit patients is treated either with rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone induction followed by consolidating high-dose chemotherapy and autologous stem cell support (R-CHOP/HD-ASCT), or with rituximab plus fractionated cyclophosphamide, vincristine, doxorubicin and dexamethasone alternating with high-dose methotrexate-cytarabine (R-hyper-CVAD/MTX-AraC) without consolidating HD-ASCT upon physicians' and patients' choice. We retrospectively analysed the outcome and therapy tolerance in patients with MCL treated with R-CHOP/HD-ASCT or R-hyper-CVAD/MTX-AraC at the University Hospital Zurich between January 1996 and January 2016. Forty-three patients were included; 29 patients received R-CHOP/HD-ASCT and 14 patients R-hyper-CVAD/MTX-AraC. Mean age at diagnosis was 54.4 years (range 38-68 years). Thirty-five patients (81.4%) completed the entire first-line therapy (n = 24 in the R-CHOP/HD-ASCT group, n = 11 in the R-hyper-CVAD group). Of those, all patients responded and 97% achieved a complete remission (CR). With a mean follow-up of 5.7 years 10-year progression-free survival (PFS) for all patients was 32% and overall survival (OS) was 76%, with no difference between the two therapy groups. Complication-induced hospitalisation rate, haematological toxicity and economic burden were significantly higher in the R-hyper-CVAD therapy group. In contrast, quality of life and global health state were better in the R-hyper-CVAD therapy group. Both first-line therapies showed similar outcome with a median OS longer than 10 years. Due to significantly lower haematological toxicity and lower economic burden, we recommend R-CHOP/HD-ASCT as first-line therapy in fit adult patients with advanced MCL.

Results of a phase II study of vorinostat in combination with intravenous fludarabine, mitoxantrone, and dexamethasone in patients with relapsed or refractory mantle cell lymphoma: an interim analysis.

PURPOSE: Mantle cell lymphoma (MCL) is a disease that frequently relapses and primarily affects elderly people. We performed an open-label, multi-center, phase II study to investigate the effect and quality of life (QoL) of treatment with vorinostat in combination with fludarabine, mitoxantrone and dexamethasone (V-FND) for relapsed or refractory MCL. METHODS: The treatment schedule was composed of four cycles of induction treatment with V-FND and subsequent consolidation therapy involving autologous hematopoietic stem cell transplantation or six cycles of vorinostat maintenance. QoL was assessed using EORTC Core Quality of Life questionnaire (EORTC QLQ-C30) every 2 cycles. RESULTS: Data from a total of 20 patients were collected for an interim analysis. The median age was 67 years (range 49-75), and 14 or the patients (70 %) were male. The full course of V-FND induction treatment was completed in 11 patients, but only three completed all six cycles of maintenance therapy. Response to V-FND was not available in two patients. Among the other 18 patients, the objective response rate was 77.8 % (complete response in five patients + partial response in nine patients). Median progression-free survival was 9.3 months [95 % confidence interval (CI) 4.0-12.3]. Fifteen patients (75 %) experienced grade 3/4 toxicities. Analysis of QoL demonstrated significant deterioration of social functioning (p = 0.01), and significant aggravation of fatigue and nausea/vomiting (p = 0.04 and 0.01, respectively) after two cycles of V-FND induction. CONCLUSIONS: V-FND is effective in patients with relapsed or refractory MCL. However, significant toxicities were hurdles to sustained V-FND therapy.

Management of mantle cell lymphoma in the elderly.

The average age of patients diagnosed with mantle cell lymphoma appears to be increasing. Although the majority of patients are now diagnosed in their seventh or eighth decade of life, the populations reported in clinical trials tend to be considerably younger. Recently, cooperative groups around the world have begun to focus on older patients, with clinical trials yielding important and sometimes surprising results. Novel (and some not-so-novel) therapies are increasingly being evaluated as a means to improve quality of life, not just progression-free survival. Simultaneously, a growing interest in geriatric oncology has resulted in improvements in our ability to identify individuals at risk for treatment-related morbidity and mortality. Treatment recommendations for the older patient must take into account all of these developments and should take care not to oversimplify or dichotomize patients based on chronological age alone. Just as there are some older patients that may benefit from more aggressive therapies, there are likely some younger patients that would benefit from less intensive regimens. As always, a better understanding of lymphoma biology will lead the way to better treatments, and enrollment in clinical trials is recommended.

Durable responses with the metronomic rituximab and thalidomide plus prednisone, etoposide, procarbazine, and cyclophosphamide regimen in elderly patients with recurrent mantle cell lymphoma.

BACKGROUND: Targeting the tumor microenvironment and angiogenesis is a novel lymphoma therapeutic strategy. The authors report safety, activity, and angiogenic profiling results with the rituximab and thalidomide plus prednisone, etoposide, procarbazine, and cyclophosphamide (RT-PEPC) regimen in patients with recurrent mantle cell lymphoma (MCL). METHODS: RT-PEPC included induction (Months 1-3) of rituximab 4 times weekly, daily thalidomide (50 mg), and PEPC followed by maintenance thalidomide (100 mg), oral PEPC titrated to the neutrophil count, and rituximab every 4 months. Endpoints included safety, efficacy, quality of life (QoL), and translational studies, including tumor angiogenic phenotyping, plasma vascular endothelial growth factor (VEGF), and circulating endothelial cells. RESULTS: Twenty-five patients were enrolled, and 22 were evaluable. The median age was 68 years (range, 52-81 years), 24 patients (96%) had stage III or IV disease, 18 patients (72%) had an International Prognostic Index (IPI) score of 3 to 5, and 20 patients (80%) had high-risk Mantle Cell International Prognostic Index (MIPI) scores. Patients had received a median of 2 previous therapies (range, 1-7 previous therapies), and 15 patients (60%) had progressed on bortezomib. At a median follow-up of 38 months, the overall response rate was 73% (complete response [CR]/unconfirmed CR rate, 32%; partial response [PR] rate, 41%; n = 22 patients), and the median progression-free survival was 10 months. Four CRs were ongoing (> or =6 months, > or =31 months, > or =48 months, and > or =50 months). Toxicities included grade 1 and 2 fatigue, rash, neuropathy, and cytopenias, including grade 1 and 2 thrombocytopenia (64%) and grade 3 and 4 neutropenia (64%). Two thromboses and 5 episodes of grade 3 or 4 infections occurred. QoL was maintained or improved. Correlative studies demonstrated tumor autocrine angiogenic loop (expression of VEGF A and VEGF receptor 1) and heightened angiogenesis and lymphangiogenesis in stroma. Plasma VEGF levels and circulating endothelial cells trended down with treatment. CONCLUSIONS: RT-PEPC had significant and durable activity in MCL with manageable toxicity and maintained QoL. Novel, low-intensity approaches warrant further evaluation, potentially as initial therapy in elderly patients.
