RESUMO

Health-related quality of life (HRQoL) data are important indicators of health status in patients with lymphoma. The objective of this analysis was to assess the impact of treatment with Sandoz rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) on HRQoL in treatment-naïve adult patients with diffuse large B-cell lymphoma (DLBCL) included in the prospective, real-world REFLECT study. REFLECT is the first prospective study to assess HRQoL in patients with DLBCL treated with a rituximab biosimilar. HRQoL was assessed via the patient-reported European Organization for Research and Treatment of Cancer Core Quality of Life questionnaire at baseline, mid-treatment (month 3), end of treatment (month 6), and follow-up (months 9 and 12). Subgroup analyses were performed to evaluate the influence of baseline characteristics on HRQoL, and associations between baseline HRQoL and treatment response. HRQoL was assessed in 169 patients. Mean global health status score remained stable from baseline (54.8) to mid-treatment (month 3; 54.7), before steadily improving through to end of treatment (month 6; 61.4), and follow-up month 9 (64.9) and month 12 (68.8). Similar trends were observed across most functional and symptom subscales. Higher cognitive, physical, or role functioning, and less appetite loss, diarrhea, fatigue, or pain at baseline, were all associated with an improved likelihood of reaching a complete versus partial response at the end of treatment. Overall, these findings confirm the HRQoL benefits of R-CHOP therapy in treatment-naïve adult patients with DLBCL, and suggest that baseline HRQoL may be predictive of treatment response.

RESUMO

AIMS: There are multiple recently approved treatments and a lack of clear standard-of-care therapies for relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL). While total cost of care (TCC) by the number of lines of therapy (LoTs) has been evaluated, more recent cost estimates using real-world data are needed. This analysis assessed real-world TCC of R/R DLBCL therapies by LoT using the IQVIA PharMetrics Plus database (1 January 2015-31 December 2021), in US patients aged ≥18 years treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) or an R-CHOP-like regimen as first-line therapy. METHODS: Treatment costs and resources in the R/R setting were assessed by LoT. A sensitivity analysis identified any potential confounding of the results caused by the impact of the COVID-19 pandemic on healthcare utilization and costs. Overall, 310 patients receiving a second- or later-line treatment were included; baseline characteristics were similar across LoTs. Inpatient costs represented the highest percentage of total costs, followed by outpatient and pharmacy costs. RESULTS: Mean TCC per-patient-per-month generally increased by LoT ($40,604, $48,630, and $59,499 for second-, third- and fourth-line treatments, respectively). Costs were highest for fourth-line treatment for all healthcare resource utilization categories. Sensitivity analysis findings were consistent with the overall analysis, indicating results were not confounded by the COVID-19 pandemic. LIMITATIONS: There was potential misclassification of LoT; claims data were processed through an algorithm, possibly introducing errors. A low number of patients met the inclusion criteria. Patients who switched insurance plans, had insurance terminated, or whose enrollment period met the end of data availability may have had truncated follow-up, potentially resulting in underestimated costs. CONCLUSION: Total healthcare costs increased with each additional LoT in the R/R DLBCL setting. Further improvements of first-line treatments that reduce the need for subsequent LoTs would potentially lessen the economic burden of DLBCL.

RESUMO

Aim: To assess treatment patterns, healthcare resource utilization (HCRU), and costs for patients with diffuse large B-cell lymphoma (DLBCL) who did not receive stem cell transplantation in second-line. Patients & methods: An administrative MarketScan® database study to assess DLBCL claims from 01/01/2009-30/09/2020. Results: Most patients (n = 750) received rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone in first-line (86.8%) and rituximab (39.5%) or bendamustine ± rituximab ± other (16.3%) in second-line. Over half were hospitalized (mean duration: 16.5 (standard deviation [SD]: 25.8) days per patient per year). Mean medical/pharmacy costs were US$141,532 per patient per year (SD: $189,579), driven by DLBCL-related claims. Conclusion: Healthcare resource utilization and costs for DLBCL-related claims were due to hospitalizations and outpatient visits. Novel therapies to reduce clinical and economic burdens are needed.

RESUMO

Objective: To evaluate treatment patterns, healthcare resource utilization (HRU) and costs among peripheral T-cell lymphoma (PTCL) patients in the USA. Methods: A retrospective cohort study, using the IQVIA PharMetrics® Plus claims database from 1 April 2011 to 30 November 2021, identified PTCL patients receiving systemic treatments. Three mutually exclusive subcohorts were created based on line of therapy (LOT): 1LOT, 2LOT and ≥3LOT. Common treatment regimens, median time on treatment, all-cause and PTCL-related HRU and costs were estimated. Results: Among 189 PTCL patients identified, 61.9% had 1LOT, 21.7% had 2LOT and 16.4% had ≥3LOT. The most common treatment regimens in the 1LOT were CHOP/CHOP-like, CHOEP/CHOEP-like and brentuximab vedotin; monotherapies were most common in the 2LOT and ≥3LOT. All-cause and PTCL-related hospitalizations and prescriptions PPPM increased with increasing LOT. Nearly 70% of total treatment costs were PTCL related. Conclusion: Higher utilization of combination therapies in the 1LOT and monotherapies in subsequent LOTs were observed, alongside high PTCL-related costs.


Peripheral T-cell lymphomas (PTCL) are a rare and fast-growing form of blood cancer. About 8000­12,000 people in the USA are diagnosed with PTCL every year. As it is a rare disease and has many types, and there is a limited understanding of the patients who have PTCL and the treatments they receive in the real world. The purpose of this study was to evaluate how these patients are treated, what are they treated with and what are the costs of these treatments in the USA. The data collected on these patients was divided into three groups based upon the number of lines of treatment/therapy (LOT) they received: 1LOT, 2LOT and ≥3LOT. This study researched different treatments and their duration in each line of therapy. Among 189 PTCL patients included in the study, the average age of patients was 55 years and 62% were male. Among these patients, 62% had 1LOT, 22% had 2LOT and 16% had ≥3LOT. The most common treatments in the 1LOT were traditional chemotherapy regimens followed by targeted therapies: CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone) or CHOP-like, CHOEP (cyclophosphamide, doxorubicin, vincristine, etoposide and prednisone) or CHOEP-like, and brentuximab vedotin. Treatment regimens with only one drug were most common in the 2LOT and ≥3LOT. The total cost of PTCL treatment in the USA is very high; 70% of this cost is related to their treatment with various drugs. More research is needed to better understand the treatment and cost of this rare cancer.

RESUMO

BACKGROUND: Spinal muscular atrophy (SMA) type 1 is a severe condition leading to early respiratory failure. Treatment options have become available, yet respiratory outcome measures in SMA type 1 are limited. The aim of this study was to assess the respiratory pattern in SMA type 1 patients via structured light plethysmography (SLP). SLP measures the thoraco-abdominal movements by projecting a light grid onto the anterior thoraco-abdominal surface. METHODS: Cross-sectional study of consecutive children with SMA type 1. All children underwent motor assessment (CHOP-INTEND) and one-minute tidal breathing recording by SLP in supine position while self-ventilating in room air. The Respiratory rate, the abdominal vs. chest contribution to breath (Relative Expired Abdomen%, Relative Expired Chest%) and the severity of thoraco-abdominal paradox (Phase Angle) were acquired. RESULTS: Nineteen patients were included, median (IQR) age 2.3 years (1.4-7.9). Their respiratory pattern captured via SLP showed a raised median (IQR) respiratory rate per age of 33.5 bpm (26.6-41.7), a prevalent abdominal contribution to tidal breathing with median (IQR) Relative Expired Abdomen 77% (68-90) vs. Chest 23% (10-32). Thoracoabdominal paradox was detected (median Phase Angle 48.70°) and its severity correlated negatively with CHOP-INTEND (r -0.8, p < 0.01). CONCLUSIONS: SLP captured and quantified the respiratory features of infants and children with SMA type 1.

RESUMO

AIMS: We evaluated the pharmacoeconomic value of polatuzumab vedotin plus rituximab, cyclophosphamide, doxorubicin, and prednisone (Pola-R-CHP) in previously untreated diffuse large B-cell lymphoma (DLBCL) versus rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). MATERIALS AND METHODS: A 3-state partitioned survival model was used to estimate life years (LYs), quality-adjusted LYs (QALYs), and cost impacts of Pola-R-CHP versus R-CHOP. Analyses utilized mixture-cure survival modelling, assessed a lifetime horizon, discounted all outcomes at 3% per year, and examined both payer and societal perspectives. Progression-free survival, overall survival (OS), drug utilization, treatment duration, adverse reactions, and subsequent treatment inputs were based on data from the POLARIX study (NCT03274492). Costs included drug acquisition/administration, adverse reaction management, routine care, subsequent treatments, end-of-life care, and work productivity. RESULTS: Incremental cost-effectiveness ratios of Pola-R-CHP versus R-CHOP were $70,719/QALY gained and $88,855/QALY gained from societal and payer perspectives, respectively. The $32,824 higher total cost of Pola-R-CHP versus R-CHOP was largely due to higher drug costs ($122,525 vs $27,694), with cost offsets including subsequent treatment (-$52,765), routine care (-$1,781), end-of-life care (-$383), and work productivity (-$8,418). Pola-R-CHP resulted in an increase of 0.47 LYs and 0.46 QALYs versus R-CHOP. Pola-R-CHP was cost-effective in 60.9% and 58.0% of simulations at a willingness-to-pay threshold of $150,000/QALY gained from societal and payer perspectives, respectively. LIMITATIONS: There was uncertainty around the OS extrapolation in the model, and costs were derived from different sources. Recommended prophylactic medications were not included; prophylactic use of granulocyte colony-stimulating factor for all patients was assumed to be equal across treatment arms in POLARIX. Work productivity loss was estimated from a general population and was not specific to patients with DLBCL. CONCLUSION: Pola-R-CHP was projected to be cost-effective versus R-CHOP in previously untreated DLBCL, suggesting that Pola-R-CHP represents good value relative to R-CHOP in this setting.

RESUMO

We evaluated the cost-effectiveness of frontline polatuzumab vedotin-R-CHP (pola-R-CHP) treatment for patients with diffuse large B-cell lymphoma (DLBCL) in Germany by using a Markov model (lifetime horizon). Progression rates and survival outcomes were extrapolated from the POLARIX trial. Outcomes were measured in incremental cost-effectiveness ratios (ICERS) with a willingness-to-pay (WTP) threshold of €80 000/quality-adjusted life-years (QALY). Assuming, 69.6% 5-year PFS with pola-R-CHP and 62.6% 5-year PFS with R-CHOP, the addition of polatuzumab vedotin resulted in an additional 0.52 life-years and an incremental 0.65 QALYs but €31 988 additional cost. Based on this, pola-R-CHP was cost-effective (€49 238/QALY) at a WTP of €80 000/QALY. The cost-effectiveness of pola-R-CHP is highly dependent on its long-term outcomes and cost. Our analysis is limited by the fact that the long-term outcomes of pola-R-CHP are unknown at this time.

RESUMO

PURPOSE: Follicular lymphoma (FL) is one of the most common lymphoma. Occasionally, FL is associated with tumoral epidural compression and management of these patients remain poorly codified. This study aims to report incidence, clinical characteristics, management and outcomes of patients with FL and tumoral epidural compression. MATERIAL AND METHODS: Observational, retrospective cohort study of adult patients with FL and epidural tumor compression, treated in a French Institute over the last 20 years (2000-2021). RESULTS: Between 2000 and 2021, 1382 patients with FL were followed by the haematological department. Of them, 22 (1.6%) patients (16 men and 6 women) had follicular lymphoma with epidural tumor compression. At epidural tumor compression occurrence, 8/22 (36%) patients had a neurological clinical deficit (motor, sensory or sphincter function) and 14/22 (64%) had tumor pain. All patients were treated with immuno-chemotherapy; the main regimen being used was R-CHOP plus high dose IV methotrexate in 16/22 (73%) patients. Radiotherapy for tumor epidural compression was performed in 19/22 (86%) patients. With a median follow-up of 60 months (range=[1-216]), 5 year local tumor relapse free survival was achieved in 65% (95% CI 47-90%) of patients. The median PFS was of 36 months (95% CI 24-NA) and 5 years OS estimate was 79% (95% CI 62-100%). Two patients developed a relapse at a second epidural site. CONCLUSION: FL with tumoral epidural compression reached 1.6% of all FL patients. Management based on immuno-chemotherapy with radiotherapy appeared to produce comparable outcomes with the general FL population.

RESUMO

Introduction: This study aimed to evaluate the effectiveness of selective laser photocoagulation of communicating vessels (SLPCV) on cardiac function in twins with twin-to-twin transfusion syndrome (TTTS). Methods: This retrospective cohort study evaluated 178 women with twin pregnancies complicated with TTTS and scheduled for SLPCV between 16 and 26 weeks of gestation. The severity of TTTS was determined by Quintero staging and the severity of cardiovascular disorders by the CHOP (Children's Hospital of Philadelphia) score. Patient survival was evaluated through a one-month-after-birth follow-up of fetuses. Results: The study revealed significant improvements in Doppler indices in both donors and recipients after SLPCV. The CHOP score also significantly decreased after the intervention. One-month-after-birth survival rates were 55.1% in donors and 56.7% in recipients. Some Doppler indexes of fetuses before SLPCV could predict survival until one month after birth. Conclusion: The study suggests that SLPCV can improve cardiac function in fetuses with TTTS and that some Doppler indexes can predict survival outcomes. Additionally, the severity of TTTS can be a powerful indicator of the severity of cardiovascular complications.

RESUMO

BACKGROUND: One key clinical challenge remains in how to sequence treatments in follicular lymphoma (FL). The chemoimmunotherapy rituximab cyclophosphamide, doxorubicin, vincristine (Oncovin), and prednisone (R-CHOP) has been a standard treatment option for two decades. However, there are limited data to suggest in which line R-CHOP should be used for older patients. PATIENTS AND METHODS: We leveraged population-based surveillance, epidemiology, and end results-medicare data and identified 675 patients aged ≥65 years newly diagnosed with FL from 2000 to 2009 who received R-CHOP in either the first or second line. We estimated restricted mean survival time using Kaplan-Meier curves, propensity scores (PS), and regression models comparing patients who received R-CHOP as a first versus second line. RESULTS: We found that patients who received R-CHOP as first line had significantly longer 9-year RMST than those who received R-CHOP in the second line using Kaplan-Meier curves (P = .01), PS stratification (P = .002), PS matching (P = .005), and the inverse of PS as the treatment weight (P < .0001). The subgroup analyses using linear regression models showed that the 9-year restricted mean survival time of patients who received R-CHOP as the first line was longer in patients aged ≥80 years (P = .002) and with histological grade 1 or 2 (P = .02), compared to those who received R-CHOP as second line. CONCLUSION: R-CHOP given in the first line was associated with longer overall survival compared to R-CHOP given as second line for older patients with FL.

RESUMO

AIMS: To support reimbursement requests in Canada, we evaluated the cost-effectiveness of brentuximab vedotin (Adcetris) in combination with cyclophosphamide, doxorubicin, and prednisone (A + CHP) compared with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) as frontline treatment for CD30-expressing peripheral T-cell lymphomas (PTCLs) using results from the ECHELON-2 clinical trial. The PTCL subtypes included were systemic anaplastic large cell lymphoma (sALCL), PTCL-not otherwise specified (PTCL-NOS), and angioimmunoblastic T-cell lymphoma (AITL). MATERIALS AND METHODS: A partitioned survival model consisting of three health states (progression-free survival [PFS], post-progression survival [PPS], and death) was constructed from the perspective of the Canadian publicly funded healthcare system over a lifetime horizon. Efficacy, safety, and health-related quality-of-life (HRQoL) data were obtained from ECHELON-2. Medical resource use and costs were derived from Canadian literature and standard sources. Incremental cost-effectiveness ratios (ICERs) per life-years (LYs) and quality-adjusted life-years (QALYs) gained were calculated. Sensitivity analyses were performed to account for uncertainty in key parameters. All costs are reported in Canadian dollars. RESULTS: A + CHP, when compared with CHOP, was associated with an estimated mean gain of 2.90 LYs and 2.38 QALYs and a mean incremental cost of $76,491. The ICER for A + CHP compared with CHOP was estimated at $26,340 per LY gained and $32,177 per QALY gained. In sensitivity analyses, the ICERs remained below $60,000 per QALY gained. Time horizon, patient starting age, and discount rate affected the results, as the ICER was driven by long-term survival gains observed with A + CHP compared with CHOP. LIMITATIONS: Real-world downstream treatments (such as stem cell transplantation) may differ from the treatment protocol followed in the ECHELON-2 trial. CONCLUSIONS: A + CHP compared with CHOP provides a cost-effective treatment option with improved clinical outcomes that are clinically relevant and a comparable safety profile for adults with previously untreated CD30-expressing sALCL, PTCL-NOS, or AITL in Canada.

RESUMO

OBJECTIVE: Limited real-world information exists on the characteristics or treatment patterns of patients with peripheral T-cell lymphoma (PTCL). We reported demographics, treatments and direct healthcare resource utilization (HRU) in a large cohort of US patients newly diagnosed with PTCL. METHODS: Patients aged ≥18 years with a PTCL diagnosis between January 2011 and December 2016 were identified from the Inovalon MORE2 Registry. Continuous medical/pharmacy enrollment 6-months prior to and ≥1-month after the first PTCL diagnosis was required. The main focus of this study was on newly diagnosed patients receiving cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) versus other chemotherapy. RESULTS: A total 2971 patients with PTCL and chemotherapy information were included in the study; 1706 (57%) received CHOP and 1265 (43%) other chemotherapy. A majority of patients (51.7%) were female; mean (standard deviation) age at index was 61.0 (±16.0), Charlson score was 4.1 (±2.9), and follow-up time was 24.6 (±16.7) months. During the variable follow-up period, HRU was similar for the CHOP and other chemotherapy cohorts; 58.1% and 59.3% had ≥1 all-cause hospitalizations, respectively. The proportion of patients with ≥1 PTCL-related hospitalizations was higher in the CHOP than in the other chemotherapy cohort (40.3% vs. 9.7%, respectively) and mean length of stay was longer (4.6 vs. 3.7 days per patient per month, respectively). CONCLUSIONS: This retrospective analysis of patients with PTCL revealed high levels of comorbidity and HRU; novel interventions that improve patient outcomes and reduce the HRU burden of PTCL are needed.

RESUMO

Background: Recent progress in the therapies used in patients with Non- Hodgkin's lymphoma has improved survival. The incidence has been reported to be decreasing in the last few years, accounting for 4% of all cancers. This study analyzed time trends for incidence, mortality, and prevalence of NHL. Methods: We analyzed the SEER Cancer Database from 1997 to 2015. Join point regression analysis was used to determine age-adjusted incidence rates, 24-month relative survival rate, and to identify racial/ethnic groups with a lower survival. Results: The trend in incidence of NHL decreased between 2008 and 2011 at an annual percentage change rate of 3.74%. The male predominance among NHL patients between 1997-2015 was 57%. The number of male patients affected with NHL has been similar in the last 20 years. Female predominance with NHL was higher in 1998 at 46 %, and lower in 2010 at 42.85%. The 24-month relative survival rate was higher among white patients as compared to black patients with NHL. Conclusions: Our analysis demonstrated that the incidence of Non-Hodgkin's Lymphoma has decreased among minorities; however, the outcomes are inferior in terms of survival. This analysis showed an inferior 24-month relative survival rate among black patients compared with white patients. This analysis demonstrates the need for further research in NHL to determine the biological differences and social factors that influence the lower survival among black patients with NHL.

RESUMO

For follicular lymphoma (FL) with grade 1/2, the complete response (CR) rate of the first-line R-CHOP treatment was significantly low. In this study, we assessed the rationality of the administration of rituximab for FL patients with grade 1/2 based on concentration-response relationship analyses. Thus, we conducted a prospective pharmacokinetic (PK) study in 68 FL patients with grades 1-3 treated with R-CHOP at 21-day intervals. Plasma rituximab concentrations were quantified using ELISA and the population PK modeling was established with Phoenix® NLMETM. The first cycle trough concentration (C1-trough) of rituximab was a significant independent risk factor for achieving CR in matched-pair logistic regression analysis, rather than the concentrations in later cycles; the recommendatory minimum optimal C1-trough was 13.60 µg/mL. Patients with grade 1/2 had significantly lower C1-trough compared with grade 3 (12.21 µg/mL vs. 23.45 µg/mL, P < 0.001), only 30% patients with grade 1/2 could reach 13.60 µg/mL, compared with 91.67% in patients with grade 3, which was in accord with its unsatisfactory CR rates (43.33% vs. 76.32%). The stage indicating the tumor burden (the target) was a crucial influence factor for C1-trough, accounting for 40.70% of its variability, 70% patients with grade 1/2 were stage IV in this study, since the systemic therapy only started at the disseminated disease stage. The initial dose of 1800 mg was recommended by Monte Carlo simulation for patients with grade 1/2. In summary, low C1-trough accounted for low-grade FL's unsatisfactory CR rate, designing the first dosage of rituximab should be a very important component of individualized therapy for FL.

RESUMO

BACKGROUND: The optimal chemotherapy regimen for treating HIV associated NHL in low resource settings is unknown. We conducted a retrospective study to describe survival rates, treatment response rates and adverse events in patients with HIV associated NHL treated with CHOP and dose adjusted-EPOCH regimens at the Uganda Cancer Institute. METHODS: A retrospective study of patients diagnosed with HIV and lymphoma and treated at the Uganda Cancer Institute from 2016 to 2018 was done. RESULTS: One hundred eight patients treated with CHOP and 12 patients treated with DA-EPOCH were analysed. Patients completing 6 or more cycles of chemotherapy were 51 (47%) in the CHOP group and 8 (67%) in the DA-EPOCH group. One year overall survival (OS) rate in patients treated with CHOP was 54.5% (95% CI, 42.8-64.8) and 80.2% (95% CI, 40.3-94.8) in those treated with DA-EPOCH. Factors associated with favourable survival were BMI 18.5-24.9 kg/m2, (p = 0.03) and completion of 6 or more cycles of chemotherapy, (p < 0.001). The overall response rate was 40% in the CHOP group and 59% in the DA-EPOCH group. Severe adverse events occurred in 19 (18%) patients in the CHOP group and 3 (25%) in the DA-EPOCH group; these were neutropenia (CHOP = 13, 12%; DA-EPOCH = 2, 17%), anaemia (CHOP = 12, 12%; DA-EPOCH = 1, 8%), thrombocytopenia (CHOP = 7, 6%; DA-EPOCH = 0), sepsis (CHOP = 1), treatment related death (DA-EPOCH = 1) and hepatic encephalopathy (CHOP = 1). CONCLUSION: Treatment of HIV associated NHL with curative intent using CHOP and infusional DA-EPOCH is feasible in low resource settings and associated with > 50% 1 year survival.

RESUMO

Aim of this study is to determine the influence of the basic conditions of the traumatic interaction of cutting and chopping objects with 'barrier' tissues of the scalp on the formation of morphological signs of damage. It was suggested to perform the comparative analysis of the morphological signs of incised and chopped scalp tissue wounds obtained by changing one given parameter in experimental damage modeling. The influence of the basic conditions of the traumatic interaction of cutting and chopping objects with the 'barrier' tissues of the scalp on the formation of morphological signs of the resulting damage was determined. The effectiveness of the proposed comparative analysis of morphological signs of incised and chopped lesions was confirmed.

RESUMO

BACKGROUND: Despite effective therapies, outcomes for diffuse large B-cell lymphoma (DLCBL) remain heterogeneous in older individuals due to comorbid diseases and variations in disease biology. METHODS: Using the Surveillance, Epidemiology, and End Results (SEER)-Medicare database, the authors conducted a multistate survival analysis of 11,780 patients with DLBCL who were aged ≥65 years at the time of diagnosis (2002-2009). Cox proportional hazards models were used to specify the impact of prognostic factors on overall survival and cause-specific deaths, and the Aalen-Johansen estimator was used to project the course of DLBCL over time with or without standard therapy with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). RESULTS: Advanced age (hazard ratio [HR] for ages 71-75 years: 1.25; HR for ages 76-80 years: 1.46; HR for ages 81-85 years: 1.88; and HR for age ≥86 years: 2.26), DLBCL stage (HR for Ann Arbor stage II: 1.28; HR for stage III: 1.54; and HR for stage IV: 1.95), Charlson Comorbidity Index (CCI) ≥1 (HR for CCI of 1, 1.15; and HR for CCI >1, 1.37), and not being married (HR, 1.12) were associated with an increased risk of DLBCL-specific death. Being female (HR, 0.91) and of higher socioeconomic status (HR, 0.91) were associated with a lower risk of DLBCL-related mortality after therapy. For patients treated with R-CHOP (3610 patients), the risk of death due to DLBCL was 14.0% and 18.6%, respectively, at 2 and 5 years of treatment and plateaued afterward, confirming a 5-year "cure" point while receiving R-CHOP among older patients. CONCLUSIONS: Conducting a survival analysis over a large data set, the current study evaluated competing risks for death within a multistate modeling framework, and identified age, sex, and CCI as risk factors for DLBCL-specific and other causes of death.

RESUMO

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.

RESUMO

AIM: After detection of obstructive uropathy (OU), the indication for or against surgery is primarily based on the differential renal function (DRF). This is to compare functional magnetic resonance urography (fMRU) with dynamic renal scintigraphy (DRS) to assess OU and DRF in infants and children. PATIENTS, METHODS: Retrospective analysis in 30 patients (female: 16; male: 14; median age: 5.5 years [0.2-16.5]), divided into subgroup A (age: 0-2 years; n = 16) and B (> 2-17 years; n = 14). fMRU was assessed by measuring renal transit time (RTT) and volumetric DRF with CHOP fMRU tool (CT) and ImageJ MRU plug-in (IJ). OU detection by fMRU was compared with DRS (standard of reference) using areas under the curves (AUC) in ROC analyses. Concordant DRF was assumed if absolute deviation between fMRU and DRS was ≤ 5 %. RESULTS: DRS confirmed fixed OU in 4/31 kidneys (12.9 %) in subgroup A. AUC of CT was 0.94 compared with 0.93 by IJ. Subgroup B showed fixed OU in 1/21 kidneys (4.8 %) with AUCs of 0.98 each. RTT measured neither by CT nor by IJ in confirmed fixed OU was < 1200 s - resulting in negative predictive values of 1.0 each. In subgroup A, DRF was concordant in 81.3 % of the kidneys for CT and DRS compared with 75.0 % for IJ and DRS. In subgroup B, CT and DRS were concordant in 91.7 %, and IJ and DRS in 45.8 % of the kidneys. CONCLUSION: fMRU accurately excluded fixed OU in infants and children, independent from the software used for quantification. However, assessment of DRF with fMRU deviated from DRS especially in infants who may profit most from early intervention. Thus, fMRU cannot fully replace DRS as primary functional examination. If, for clinical reasons, fMRU is performed in first place and it cannot exclude fixed OU, it should be followed by DRS for validation and DRF quantification.

RESUMO

BACKGROUND: Mantle cell lymphoma (MCL) is a rare and aggressive form of non-Hodgkin's lymphoma. Bortezomib is the first product to be approved for the treatment of patients with previously untreated MCL, for whom haematopoietic stem cell transplantation is unsuitable, and is used in combination with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (VR-CAP). The National Institute of Health and Care Excellence recently recommended the use of VR-CAP in the UK following a technology appraisal. We present the cost effectiveness analysis performed as part of that assessment: VR-CAP versus the current standard of care regimen of rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) in a UK setting. METHODS: A lifetime economic model was developed with health states based upon line of treatment and progression status. Baseline patient characteristics, dosing, safety and efficacy were based on the LYM-3002 trial. As overall survival data were immature, survival was modelled by progression status, and post-progression survival was assumed equal across arms. Utilities were derived from LYM-3002 and literature, and standard UK cost sources were used. RESULTS: Treatment with VR-CAP compared to R-CHOP gave an incremental quality-adjusted life year (QALY) gain of 0.81 at an additional cost of £16,212, resulting in a base case incremental cost-effectiveness ratio of £20,043. Deterministic and probabilistic sensitivity analyses showed that treatment with VR-CAP was cost effective at conventional willingness-to-pay thresholds (£20,000-£30,000 per QALY). CONCLUSIONS: VR-CAP is a cost-effective option for previously untreated patients with MCL in the UK.
