Relaxation and exercise in lymphoma survivors (REIL study): a randomised clinical trial protocol.

Background: Lymphoma survivors commonly report ongoing complaints including fatigue, pain, depression and decreased quality of life (QoL) following treatment. Although evidence suggests that both relaxation and exercise can significantly improve such symptoms, there is no consensus on which intervention is more effective. This paper presents the REIL (Relaxation and Exercise In Lymphoma) Study protocol. The REIL study aims to compare the effect of two home-based interventions - relaxation and exercise - on QoL in lymphoma survivors. Methods: Eligible participants (n = 36) will be randomised to a relaxation or exercise programme to perform at least three times per week. The primary outcome measure is QoL, assessed by the European Organisation for Research and Treatment of Cancer QoL Questionnaire Core 30 (EORTC QLQ-C30). Secondary outcome measures include body composition, cardiovascular status, pulmonary function, grip strength, functional exercise capacity (six minute walk test), well-being assessed by the FACT-Lym questionnaire, and psychological status assessed by the Hospital Anxiety and Depression Scale. Total duration of the study will be twelve weeks and outcome measures will be assessed at baseline, six weeks and at the end of the study. Discussion: It is anticipated that results from this preliminary study will begin to highlight effective pathways to improve QoL following chemotherapy for this population. This will better inform healthcare professionals to optimise QoL of lymphoma patients, and enable a smooth transition from being a cancer patient to survivor. Trial registration: The REIL study has been registered on a publicly accessible database, ClinicalTrials.gov, Registration Number: NCT02272751, October 2014

Long-Term Response and Remission with Pixantrone in Patients with Relapsed or Refractory Aggressive Non-Hodgkin Lymphoma: Post-Hoc Analysis of the Multicenter, Open-Label, Randomized PIX301 Trial.

BACKGROUND: Pixantrone is recommended in relapsed and refractory non-Hodgkin lymphoma (NHL) or heavily pretreated NHL patients. Its conditional approval in Europe was based on results from the open-label, randomized, phase 3 PIX301 study, comparing pixantrone monotherapy with physician's choice of treatment in 140 patients with relapsed or refractory aggressive NHL. METHODS: This post-hoc analysis of the PIX301 study investigated possible correlations between patient characteristics and clinical response in 17 patients (24%) treated with pixantrone who achieved a complete response (CR) or an unconfirmed complete response (CRu) at study end. RESULTS: These patients (10 male and 7 female) had a median age of 61 (range 41-75) years, and the most common diagnoses were diffuse large B-cell lymphoma (n = 10) and transformed indolent lymphoma (n = 4). Most had received two prior lines of therapy (n = 12). There was wide variation in the time from diagnosis to study entry (219-4777 days). Among the 17 patients who achieved a CR/CRu with pixantrone, 6 had stable or progressive disease as a response to their last regimen, 7 had a partial response, and 4 had a CR/CRu. Four patients from the pixantrone group survived without progression for more than 400 days. Prior response to previous therapies did not appear to affect long-term response to pixantrone. CONCLUSIONS: These observations suggest that pixantrone monotherapy in patients with multiply relapsed or refractory aggressive NHL who had received at least two prior therapies can be associated with durable responses and long-term remission, and this may be unrelated to the clinical response to the last therapy

Maximum tumor diameter is associated with event-free survival in PET-negative patients with stage I/IIA Hodgkin lymphoma.

Introduction: the high cure rates achieved in early-stage (ES) Hodgkin lymphoma (HL) are one of the great successes of hemato-oncology, but late treatment-related toxicity undermines long-term survival. Improving overall survival and quality of life further will require maintaining disease control while potentially de-escalating chemotherapy and/or omitting radiotherapy to reduce late toxicity. Accurate stratification of patients is required to facilitate individualized treatment approaches. Response assessment using 18F-fluorodeoxyglucose positron emission tomography (PET) is a powerful predictor of outcome in HL,1,2 and has been used in multiple studies, including the United Kingdom National Cancer Research Institute Randomised Phase III Trial to Determine the Role of FDG–PET Imaging in Clinical Stages IA/IIA Hodgkin’s Disease (UK NCRI RAPID) trial, to investigate whether patients achieving complete metabolic remission (CMR) can be treated with chemotherapy alone.3-5 These PET-adapted trials have demonstrated that omitting radiotherapy results in higher relapse rates, but without compromising overall survival.3-5 For the 75% of patients who achieved CMR in RAPID, neither baseline clinical risk stratification (favorable/unfavorable) nor PET (Deauville score 1/2) predicted disease relapse; additional biomarkers are needed.1 Tumor bulk has long been recognized as prognostic in HL,1,6 but there remains uncertainty about the significance and definition of bulk in the era of PET-adapted treatment.7 We performed a subsidiary analysis of RAPID to assess the prognostic value of baseline maximum tumor dimension (MTD) in patients achieving CMR. Methods: ee have previously reported the RAPID trial design, primary results, and outcomes according to pretreatment risk stratification and PET score.1,3 Patients were aged 16 to 75 years with untreated ES-HL and without B-symptoms or mediastinal bulk (mass > 1/3 internal mediastinal diameter at T5/6).6 Metabolic response after 3 cycles of ABVD chemotherapy (doxorubicin, bleomycin, vinblastine, and dacarbazine) was centrally assessed using PET (N = 562). Patients with CMR (ie, Deauville score 1-2) were randomly assigned to receive involved field radiotherapy (IFRT; n = 208) or no further therapy (NFT; n = 211). PET-positive patients (score, 3-5; n = 143) received a fourth cycle of ABVD and IFRT. Baseline disease assessment was performed by computed tomography, and bidimensional target lesion measurements were reported by local radiologists in millimeters. The association of baseline MTD with HL-related event-free survival (EFS: progression or HL-related death) and progression-free survival (PFS) (progression or any-cause death) was assessed using Kaplan-Meier and Cox regression analyses. Non-HL deaths were either related to primary treatment toxicity or occurred in HL remission.1 United Kingdom ethical approval for the RAPID trial was via the UK Multicentre Research ethics committee. Results and discussion: baseline patient characteristics have been previously described.1 Median age was 34 years (range, 16-75 years); 184 (37.4%) of 492 patients had unfavorable risk by European Organisation for Research and Treatment of Cancer criteria, and 155 (32.3%) of 480 by German Hodgkin Study Groupcriteria. Median MTD for patients achieving CMR was 3.0 cm (interquartile range, 2.0-4.0 cm) and 3.0 cm (interquartile range, 1.8-4.5 cm) in the NFT and IFRT groups, respectively, whereas PET-positive patients had a median MTD of 3.9 cm (interquartile range, 2.8-5.1 cm). After a median follow-up of 61.6 m, 44 HL progression events occurred: 21 NFT, 9 IFRT and 14 PET-positive. No patient received salvage treatment without documented progression. Only 5 HL-related deaths occurred (1 IFRT, 4 PET-positive), and 12 non-HL deaths (4 NFT, 6 IFRT, 2 PET-positive).1 For patients with CMR (N = 419), there was a strong association between MTD and EFS (hazard ratio [HR], 1.19; 95% confidence interval [CI], 1.02-1.39; P = .02), adjusting for treatment group, with an approximate 19% increase in HL risk per centimeter increase in MTD. The association was similar in both treatment groups (NFT HR, 1.20 [95% CI, 0.99-1.44; P = .06]; IFRT HR, 1.19 [95% CI, 0.92-1.55; P = .19]). The observed effect sizes did not markedly change after adjusting for baseline clinical risk factors, and similar results were observed for PFS (supplemental Table 1). In contrast, for PET-positive patients, there was no association between MTD and EFS (HR, 0.88; 95% CI, 0.70-1.11; P = .29) or PFS (HR, 0.87; 95% CI, 0.70-1.08; P = .21). In an exploratory analysis within the NFT group, MTD was dichotomized using increasing 1-cm intervals to investigate the relationship between MTD thresholds and EFS. The largest effect size was observed with an MTD threshold of ≥5 cm (Table 1). Similar results were observed for PFS; this threshold also performed best in time-dependent receiver operating characteristic curve analyses. It was not possible to assess MTD thresholds in the IFRT group with only 9 events. Among all randomized patients, 79 (18.9%) had MTD of ≥5 cm, the majority with mediastinal (n = 43), supraclavicular (n = 17), or cervical (n = 16) locations. Five-year EFS for patients with MTD of ≥5 cm randomly assigned to NFT and IFRT was 79.3% (n = 39; 95% CI, 66.6%-92.0%) and 94.9% (n = 40; 95% CI, 88.0%-100%), respectively (P = .03; Figure 1)

Risk factors for chemotherapy-induced neutropenia occurrence in breast cancer patients: data from the INC-EU Prospective Observational European Neutropenia Study

BACKGROUND: Chemotherapy-induced neutropenia (CIN) places patients at risk of life-threatening infections. While reduction of chemotherapy dose or delay of the subsequent treatment cycle and, consequently, reduction of relative dose intensity (RDI) may limit myelotoxicity, these actions can also impact adversely on treatment outcome and should be avoided in adjuvant settings. PATIENTS AND METHODS: Based on data from 444 breast cancer patients in the INC-EU Prospective Observational European Neutropenia Study, we have evaluated patient-specific and treatment-specific factors that impact on the incidence of grade 4 CIN (absolute neutrophil count <0.5 x 10(9)/L), either during the first or in any cycle of (neo)adjuvant chemotherapy, across a range of regimens and doses. RESULTS: Using multivariate logistic regression analysis, risk factors for grade 4 CIN were identified as older age, lower weight, higher planned dose intensity of doxorubicin, epirubicin, or docetaxel, higher number of planned cycles, vascular comorbidity, lower baseline white blood cell count, and higher baseline bilirubin. Use of colony-stimulating factor before a neutropenic event occurred, dose delays, and dose reductions were protective against grade 4 CIN. CONCLUSIONS: By identifying risk factors for grade 4 CIN, CSF prophylaxis may be appropriately targeted to prevent low RDI in patients treated with curative intent

Impact of febrile neutropenia on R-CHOP chemotherapy delivery and hospitalizations among patients with diffuse large B-cell lymphoma

PURPOSE: This analysis from an observational study of clinical practice describes the impact of febrile neutropenia (FN) on chemotherapy delivery and hospitalizations. METHODS: Adults with diffuse large B-cell lymphoma (DLBCL) scheduled to receive ≥3 cycles of 2- or 3-weekly CHOP with rituximab (R-CHOP-14/21) were eligible. Primary outcome was incidence of FN. RESULTS:FN data were available for 409 patients receiving R-CHOP-14 and 702 patients receiving R-CHOP-21. FN incidence was R-CHOP-14, 20% (81/409) and R-CHOP-21, 19% (133/702). Rates of primary prophylaxis with granulocyte-colony stimulating factor were R-CHOP-14, 84% (345/409) and R-CHOP-21, 36% (252/702). A large number of patients experienced their first FN episode in cycle 1 (R-CHOP-14, 24/81 [30%]; R-CHOP-21, 63/133 [47%]). Multiple risk factors (≥2) for FN were more frequent in patients experiencing FN than in patients not experiencing FN (R-CHOP-14, 60/81 [74%] versus 179/328 [55%]; R-CHOP-21, 98/133 [74%] versus 339/569 [60%]). A similar trend was observed for unplanned hospitalizations (R-CHOP-14, 63/81 [78%] versus 68/328 [21%]; R-CHOP-21, 105/133 [79%] versus 100/569 [18%]). Achievement of chemotherapy relative dose intensity ≥90% was lower among patients experiencing FN than in patients not experiencing FN (R-CHOP-14, 30/81 [37%] versus 234/328 [71%]; R-CHOP-21, 83/133 [62%] versus 434/569 [76%]). CONCLUSIONS:In patients with DLBCL treated with R-CHOP-14 or R-CHOP-21, patients with an event of FN were more likely to experience suboptimal chemotherapy delivery and increased incidence of unplanned hospitalizations than those without FN. FN-related hospitalizations are likely to impact chemotherapy delivery and to incur substantial costs

The Cost-effectiveness of Pixantrone for Third/Fourth-line Treatment of Aggressive Non-Hodgkin's Lymphoma

PURPOSE: Aggressive non-Hodgkin's lymphoma (aNHL) is associated with poor long-term survival after relapse, and treatment is limited by a lack of consensus regarding standard of care. Pixantrone was studied in a randomized trial in patients with relapsed or refractory aNHL who had failed ≥ 2 lines of therapy, demonstrating a significant improvement in complete or unconfirmed complete response and progression-free survival (PFS) compared with investigators' choice of single-agent therapy. The objective of this study was to assess the health economic implications of pixantrone versus current clinical practice (CCP) in the United Kingdom for patients with multiply relapsed or refractory aNHL receiving their third or fourth line of treatment. METHODS: A semi-Markov partition model based on overall survival and PFS was developed to evaluate the lifetime clinical and economic impact of treatment of multiply relapsed or refractory aNHL with pixantrone versus CCP. The empirical overall survival and PFS data from the PIX301 trial were extrapolated to a lifetime horizon. Resource use was elicited from clinical experts, and unit costs and utilities were obtained from published sources. The analysis was conducted from the perspective of the United Kingdom's National Health Service and personal social services. Outcomes evaluated were total costs, life-years, quality-adjusted life-years (QALYs), and cost per QALY gained. Deterministic and probabilistic sensitivity analyses were conducted to assess uncertainty around the results. FINDINGS: Pixantrone was estimated to increase life expectancy by a mean of 10.8 months per patient compared with CCP and a mean gain of 0.56 discounted QALYs. The increased health gains were associated with an increase in discounted costs of approximately £18,494 per patient. The incremental cost-effectiveness ratio of pixantrone versus CCP was £33,272 per QALY gained. Sensitivity and scenario analyses suggest that the incremental cost-effectiveness ratio was sensitive to uncertainty in the PFS and overall survival estimates and the utility values associated with each health state. IMPLICATIONS: Pixantrone may be considered both clinically effective and cost-effective for patients with multiply relapsed or refractory aNHL who currently have a high level of unmet need

Relaxation versus exercise for improved quality of life in lymphoma survivors : a randomised controlled trial

Purpose: Lymphoma survivors experience persisting needs as a consequence of disease and treatment, which have an impact on quality of life (QoL). There is evidence supporting the use of relaxation and exercise to improve QoL, but there is no agreement on which is more beneficial. This study aims to compare a relaxation intervention versus an exercise intervention to determine which has a greater impact on QoL post-chemotherapy. Methods: Eligible participants (n = 46) were randomised to a relaxation or exercise intervention for 12 weeks. QoL was assessed at baseline, 6 weeks and post-intervention using the European Organisation for Research and Treatment of Cancer QoL Questionnaire Core 30 (EORTC QLQ-C30) questionnaire, which is a valid and reliable tool. The summary score and all EORTC domains were assessed. Results: There was a significant difference in QoL post-intervention between groups (p = 0.029) while adjusting for baseline QoL, with the exercise group demonstrating a larger improvement. Within-group QoL significantly improved pre- to post-intervention in both the relaxation (p = 0.036) and exercise (p = 0.004) groups. Conclusions: A self-management intervention of either exercise or relaxation can help significantly improve QoL in lymphoma survivors following chemotherapy. While exercise is preferred, a relaxation intervention would also have a beneficial impact on QoL. Implications for Cancer Survivors: Lymphoma survivors should be routinely screened and those with decreased QoL referred for an exercise programme, or relaxation for survivors who are unable to exercise or choose not to. A home-based programme can have a significant positive impact on QoL and is a feasible and effective method in the current climate. Trial registration number: Clinical Trials ID NCT0227275
