ABSTRACT

Objectives: To assess health-related quality of life (QoL) in caregivers of elderly patients with chronic disabilities receiving, or not receiving, social worker support. Methods: This multicenter open-label randomized study assigned caregivers to receive an information booklet, exclusively, or with social worker support. Caregivers completed Short Form-36 (SF-36) and Hospital Anxiety Depression Scale quarterly, and Zarit Burden Interview each semester, for 24 months. We reported caregiver QoL mean changes at 12 and 24 months (M12, M24). Longitudinal QoL analysis up to M24 used mixed models for repeated measures (MMRM). Results: Among the 179 caregivers randomized from 2015 to 2019, the SF-36 physical and mental component summary showed no significant changes at M12 and M24, in terms of neither anxiety nor burden. However, depression significantly increased (M12: 1.4 ± 4.0; M24: 1.7 ± 4.1) with significant adjusted mean increase using MMRM at M24: 3.4 [0.6-2.5] in the control group, exclusively. Conclusion: These findings call for better recognition of the social support to prevent caregiver QoL deterioration and alleviate their depression early in the course of the disease. Clinical Trial Registration: ClinicalTrials.gov, identifier NCT02626377.

ABSTRACT

The management of patients with metastatic hormone-sensitive prostate cancer (mHSPC) has been significantly modified by the availability of innovative but expensive treatments, increasing the economic burden of prostate cancer. Here, we aimed to systematically identify and review published economic evaluations (EEs) related to the treatment of mHSPC and assess their quality. A systematic search was performed of the PubMed and Cochrane databases. Three reviewers independently selected EEs by defined inclusion and exclusion criteria. They extracted all data from each EE (general information, study population, data about the EE, interventions and comparators, and outcomes). They also assessed the quality of the selected EEs according to Drummond's checklist. Fourteen EEs published between 2016 and 2021 were eligible for the systematic review. The EEs found ADT + docetaxel to be the most cost-effective of all available treatments as a first-line strategy for mHSPC (abiraterone acetate plus prednisone, enzalutamide, and apalutamide). Five EEs showed that a simple price reduction of abiraterone acetate of 50% to 75% could change the results to render this treatment also cost-effective relative to that with docetaxel. Twelve EEs were of high quality, with a Drummond score ≥ 7. Analysis of the 14 EEs identified by our systematic review, amongst which 78.6% met high quality standards, showed that ADT + docetaxel tends to be the most cost-effective alternative for mHSPC. These results were assessed by sensitivity analysis. The data provided by this systematic review help to provide a better understanding of these treatments and the better use of healthcare resources.

ABSTRACT

OBJECTIVES: Scientific advances in the last decade have highlighted the use of immunotherapy, especially immune checkpoint inhibitors, to be an effective strategy in cancer therapy. However, these immunotherapeutic agents are expensive, and their use must take into account economic criteria. Thus, the objective of the present study was to systematically identify and review published EE related to the use of ipilimumab, nivolumab or pembrolizumab in melanoma, lung cancer, head and neck cancer or renal cell carcinoma, and to assess their quality. METHODS: The systematic literature research was conducted on Medline via PubMed and the Cochrane Central Register of Controlled Trials to identify economic evaluations published before July 2018. The quality of each selected economic evaluation was assessed by two independent reviewers using the Drummond checklist. RESULTS: Our systematic review was based on 32 economic evaluations using different methodological approaches, different perspectives and different time horizons. Three-quarters of the economic evaluations are full (n = 24) with a Drummond score ≥ 7, synonymous of "high quality". Among them, 66% reported a strategy that was cost-effective. The most assessed immunotherapeutic agent was nivolumab. In patients with renal cell carcinoma or head and neck cancer, it was less likely to be cost-effective than in patients with melanoma or lung cancer. CONCLUSIONS: Whether or not these findings will be confirmed remains to be seen when market approval to cover more indications is extended and new effective immunotherapeutic agents become available.

ABSTRACT

BACKGROUND: Venous thromboembolism (VTE) is highly prevalent in cancer patients and can cause severe morbidity. VTE treatment is essential, but anticoagulation increases the risk of major bleeding. The purpose was to evaluate the impact of VTE and major bleeding on survival and to identify significant risk factors for these events in lung cancer patients. METHODS: Data were extracted from a permanent sample of the French national health information system (including hospital and out-of-hospital care) from 2009 to 2016. All episodes of VTE and major bleeding events within one year after cancer diagnosis were identified. A Cox model was used to analyse the effect of VTE and major bleeding on the patients' one-year survival. VTE and major bleeding risk factors were analysed with a Fine and Gray survival model. RESULTS: Among the 2553 included patients with lung cancer, 208 (8%) had a VTE episode in the year following diagnosis and 341 (13%) had major bleeding. Almost half of the patients died during follow-up. Fifty-six (60%) of the patients presenting with pulmonary embolism (PE) died, 48 (42%) of the patients presenting with deep vein thrombosis (DVT) alone died and 186 (55%) of those presenting with a major bleeding event died. The risk of death was significantly increased following PE and major bleeding events. VTE concomitant with cancer diagnosis was associated with an increased risk of VTE recurrence beyond 6 months after the first VTE event (sHR = 4.07 95% CI: 1.57-10.52). Most major bleeding events did not appear to be related to treatment. CONCLUSION: VTE is frequent after a diagnosis of lung cancer, but so are major bleeding events. Both PE and major bleeding are associated with an increased risk of death and could be indicators of lung cancer mortality.

ABSTRACT

Venous thromboembolism is highly prevalent in lung cancer patients. Low molecular weight heparins are recommended for long term treatment of cancer associated venous thromboembolism. Direct oral anticoagulants are however an interesting alternative as they are administered orally and don't require monitoring. There are currently studies comparing both their efficacy and tolerance for cancer patients and more and more guidelines suggest considering direct oral anticoagulants for cancer associated venous thromboembolism treatment. The objective of this study was to evaluate the budgetary impact that direct oral anticoagulants use would have for lung cancer associated venous thromboembolism treatment and prevention in France. An economic model was made to evaluate the cost of venous thromboembolism treatment and prevention among patients with primary lung cancer in France by two strategies: current guidelines versus direct oral anticoagulants use. The model was fed with clinical and economic data extracted from the French national health information system. The analysis was conducted from the national mandatory Health insurance point of view. The time horizon of the study was the evaluation of the annual management cost. Lung cancer associated venous thromboembolism management's mean cost was estimated of 836€ per patient, that is a total cost of about 40 million euros per year at a national level. A 76% decrease of this cost can be expected with direct oral anticoagulants use. However, despite their benefits, these treatments raise new issues (medication interactions, bleeding management), and would likely not be recommended for all patients.

ABSTRACT

OBJECTIVES: The economic evaluation (EE) of healthcare interventions has become a necessity. However, high quality needs to be ensured in order to achieve validated results and help making informed decisions. Thus, the objective of the present study was to systematically identify and review published pancreatic ductal adenocarcinoma-related EEs and to assess their quality. METHODS: Systematic literature research was conducted in PubMed and Cochrane to identify published EEs between 2000 and 2015. The quality of each selected EE was assessed by two independent reviewers, using the Drummond's checklist. RESULTS: Our systematic review was based on 32 EEs and showed a wide variety of methodological approaches, including different perspectives, time horizon, and cost effectiveness analyses. Nearly two-thirds of EEs are full EEs (n = 21), and about one-third of EEs had a Drummond score ≥7, synonymous with 'high quality'. Close to 50% of full EEs had a Drummond score ≥7, whereas all of partial EEs had a Drummond score <7 (n = 11). CONCLUSIONS: Over the past 15 years, a lot of interest has been evinced over the EE of pancreatic ductal adenocarcinoma (PDAC) and its direct impact on therapeutic advances in PDAC. To provide a framework for health care decision-making, to facilitate transferability and to lend credibility to health EEs, their quality must be improved. For the last 4 years, a tendency towards a quality improvement of these studies has been observed, probably coupled with a context of rational decision-making in health care, a better and wider spread of recommendations and thus, medical practitioners' full endorsement.

ABSTRACT

An increase in fibrinogen concentrate prescriptions was noticed in 2015 after several guidelines regarding their use were published. We tried to evaluate if they were used appropriately. To evaluate the conformity of the prescriptions to these guidelines, we searched for each prescription if a dosage of blood fibrinogen was made, if its result was below the limit recommended to prescribe fibrinogen concentrate, and if the posology was in line with the recommendations. Effect and security of the treatment was also evaluated. We analyzed 202 prescriptions for 117 patients. The indications are respected except for one prescription for which we could not find it. The blood fibrinogen is measured for 76% of the prescriptions, 59% of the results are below the limit recommended to prescribe. The posology is conforming to the guidelines for 73% of the prescriptions, it is below the dose recommended for 20%. Patients who were prescribed low doses seemed less at risk than the others which questions the necessity of the prescriptions. The guidelines respect depends on the emergency of the prescription situation. It would be interesting to conduct a prospective study to better explain why doses below those recommended are prescribed.

ABSTRACT

BACKGROUND: Medical progress and the lifestyle modification have prolonged life expectancy, despite the development of chronic diseases. Support and care for older subjects are often provided by a network of informal caregivers composed of family, friends and neighbors, who are essential in helping older persons to continue living at home. It has been shown that the extent and diversity of informal tasks may jeopardize the physical, mental and social wellbeing of caregivers. METHODS/DESIGN: The aim of the Informal Carers of Elderly cohort is to define, through a longitudinal study, profiles of caregivers of older patients with a diagnosis of one of the following diseases: cancer (breast, prostate, colorectal), neurodegenerative diseases (Parkinson's disease, Alzheimer's disease and similar diseases), neurovascular diseases (stroke), sensory diseases (age-related macular degeneration (AMD)) and heart disease (heart failure). Patients must be at least 60 years old and living in the region of Burgundy-Franche-Comte (France). By following the different phases of the caregiving relationship from the announcement of the diagnosis, it will be possible to assess the quality of life of caregivers, coping strategies, levels of anxiety and depression, social support and the extent of their burden. We will also evaluate the efficacy and efficiency of the implementation of a pragmatic intervention by a social worker to help informal caregivers, through a randomized interventional trial nested in the cohort. Qualitative approaches aimed at studying the caregiver/patient relationship, and situations leading to breakdown of the caregiver relationship will be also undertaken. DISCUSSION: Through an analytical and longitudinal definition of profiles of informal caregivers, this study will gather detailed information on their life courses and their health trajectory by identifying consequences associated with the concept of their role as carers. In addition, the randomized interventional trial will explore the relevance of the implementation of a supportive intervention by a social worker to help caregivers. These data will help to identify strategies that could be used to improve the existing sources of aid and to propose new approaches to help caregivers. This study will provide the opportunity to identify the most relevant means of support adapted to caregivers, and provide an impulse for new health care policies.

ABSTRACT

INTRODUCTION: The capsaïcine 8% cutaneous patch (Qutenza®) was recently approved for the management of patients with peripheral neuropathic pain (PNP). Considering its limited clinical efficacy data, its improvement of medical benefit was determined to be 5 which was insufficient to support its reimbursement in addition to diagnosis related groups'tarifs. Nevertheless its commercialization was associated with a marked interest considering the unmet therapeutic needs for patients with PNP. OBJECTIVES: Our objectives were to assess the effectiveness, the safety, and the economic impact of Qutenza® in real-life conditions. METHODS: An observational cost-consequences study was launched under the aegis of the Drug Committee of our hospital. Medical charts and prescriptions of all patients who received at least one patch application were analyzed. Effectiveness and safety were assessed after 12-week and 24-week of follow-up. The economic impact was measured within the Hospital and Health Insurance perspective and with limitation to direct costs. RESULTS: From March 2012 to October 2013, 91 patients (54.3 ± 14.1 years; 52.7% of male) received at least one application. The average follow- up duration was 188.3 ± 86.4 days. The PNP etiologies were mainly post-surgery (42.9%) and post-traumatology (20.8%). A therapeutic response (decrease of ENS score of least 30%) after 12 weeks and 24 weeks was observed in 27.9% and 37.1% of patients respectively. The SF-36 mental score was significantly improved. The safety profile was good. The application of the patch resulted in incremental costs of 154 euros per hospital stay without impact on outpatient-prescription drug expenditures. CONCLUSION: This study confirms the interest of Qutenza® for heavily pretreated, refractory patients with PNP. The clinical profile of responders has to be further investigated in large observational studies.

ABSTRACT

AIM: This retrospective study aimed to compare the efficacy of and tolerance to two center-related conventional transarterial chemoembolization (TACE) strategies in the management of unresectable hepatocellular carcinoma (HCC). PATIENTS AND METHODS: All HCC patients in whom TACE was initiated in the two centers from June 2008 to July 2011 were included. The TACE strategy performed in center 1 was "on demand" with selective injections of idarubicin, whereas the TACE strategy in center 2 was based "on scheduled" non-selective injections of epirubicin. Toxicity was evaluated using the National Cancer Institute Common Terminology Criteria for Adverse Events v4.0. RESULTS: One hundred and fifty HCC patients were included. Median time to treatment failure was significantly higher in center 1, 13.1 months vs. 7.9 months in center 2 (hazard ratio, 2.32; p<10-3 in multivariate analysis). Median overall survival was 21.1 months in center 1 vs. 18.4 months in center 2 (p=NS). The proportion of grade ≥ 3 adverse events and mean hospitalisation duration for the overall TACE treatment were significantly greater in center 2 than in center 1: 56% vs. 32% (p<0.01) and 14.2 ± 7.2 days vs. 10.3 ± 7.0 days (p<0.01), respectively. CONCLUSION: Our results failed to show any significant survival differences between two center-related TACE strategies but showed a significantly smaller proportion of grade ≥ 3 adverse events and shorter hospitalisation for the overall treatment when the "on-demand" strategy was used.

ABSTRACT

BACKGROUND: Transarterial chemoembolisation (TACE) is an effective treatment for unresectable hepatocellular carcinoma (HCC), but can cause severe toxicity. AIM: To identify predictive factors of severe TACE-related toxicity in patients with unresectable HCC. METHODS: All HCC patients who underwent TACE at the Dijon University Hospital between 2008 and 2011 were included in this retrospective study. Severe TACE-related toxicity was defined as the occurrence of any adverse event grade ≥ 4, or any adverse event that caused a prolongation of hospitalisation of >8 days, or any additional hospitalisation within 1 month after TACE. Factors predicting toxicity were identified using a logistic regression model. The robustness of the final model was confirmed using bootstrapping (500 replications). RESULTS: 124 patients were included, median age was 67 years and 90% were male; 22 patients (18%) experienced severe TACE-related toxicity. Factors that independently predicted severe TACE-related toxicity in multivariate analysis were total tumour size (OR, 1.15 cm(-1); 95%CI, 1.04-1.26; p=0.01), and high serum AST levels (OR, 1.10 per 10 IU/l; 95%CI, 1.01-1.21; p=0.04). The results were confirmed by bootstrapping. CONCLUSIONS: Total tumour size and high serum AST levels were predictive factors of severe TACE-related toxicity in this hospital-based series of patients with unresectable HCC.

ABSTRACT

Transarterial chemoembolization (TACE) is the standard treatment in patients with unresectable non-metastatic hepatocellular carcinoma (HCC). New drug eluting beads aim at improving efficacy of TACE in retaining as long as possible the anticancer drug within the tumor. Our monocentric study compares direct hospital medical costs, according to two different methods, for a first course of conventional TACE and for a first course of TACE using drug eluting beads in 30 patients with HCC. The average cost of a first course of conventional TACE valued by the analytic accounting system is 4 332 € versus 3 577 € for a first course of TACE using drug eluting beads. The average cost of a first course of conventional TACE valued by the official tariffs from the new French Diagnosis Related Group prospective payment system is 4 507 € (+175 €) versus 2 852 € (-725 €) for a first course of TACE using drug eluting beads. Our study shows that a first TACE using drug eluting beads, valued by the official tariffs from the new French Diagnosis Related Group prospective payment system, is significantly (p  =  0.006) less expensive than a first conventional TACE.

ABSTRACT

The aim of this study was to select the best candidate drug for transarterial chemoembolization by in-vitro cytotoxic evaluations of 11 anticancer drugs on three human hepatocellular carcinoma (HCC) cell lines. The SNU-398, HepG2, and SNU-449 human HCC cell lines were exposed for 30 min to 11 concentrations of doxorubicin, epirubicin, idarubicin, mitoxantrone, carboplatin, cisplatin, oxaliplatin, 5-fluorouracil, gemcitabine, mitomycin C, or paclitaxel. Cytotoxicity was measured using a quantitative colorimetric assay. For each drug and cell line, we calculated the drug concentration that caused 90% cell death (IC90). To enable comparisons of drugs with different concentration ranges, we computed the cytotoxic index (CyI) as the ratio of maximal drug concentration of more than IC90. Parameters were estimated using nonlinear regression models. Idarubicin was the most active drug on all three cell lines. With SNU-398 cells, the idarubicin CyI was 2.4-fold, 2.5-fold, 57-fold, 148-fold, and more than 58 748-fold higher than the CyIs of mitoxantrone, epirubicin, doxorubicin, gemcitabine, and other drugs, respectively. With HepG2 cells, the idarubicin CyI was 27-fold, 28-fold, 51-fold, and more than 1343-fold higher than the CyIs of doxorubicin, epirubicin, mitoxantrone, and other drugs, respectively. On the resistant SNU-449 cell line, the idarubicin CyI was 2.9-fold and 14-fold higher than the CyIs of paclitaxel and gemcitabine, respectively, the only other drugs effective on this cell line. Among 11 chemotherapeutic agents including doxorubicin, cisplatin, and epirubicin, the most effective on three HCC cell lines was idarubicin. Further clinical investigations are needed to evaluate the safety and efficacy of idarubicin for transarterial chemoembolization in HCC.

ABSTRACT

The GOELAMS 072 study showed that first-line high-dose chemotherapy (HDT) with peripheral blood stem cell transplant (PBSCT) support was superior to the standard chemotherapy regimen (cyclophosphamide, doxorubicin, vincristine and prednisone; CHOP) in adults with aggressive non-Hodgkin's lymphoma (NHL). The aim of the study was to evaluate the pharmacoeconomic profile of HDT with PBSCT support relative to standard CHOP therapy as first-line treatment in adults with aggressive NHL. We performed a cost-effectiveness analysis from the French Public Health Insurance perspective, restricted to hospital costs (euro, year 2008 values). The clinical effectiveness criterion was censured overall survival (OS) difference after a median follow-up of 4 years for the entire cohort. A total of 197 patients were included (CHOP, n = 99; HDT, n = 98). Uncertainty was assessed using non-parametric bootstrap simulations and various scenario analyses. Five-year OS did not differ significantly between groups for the entire cohort. Nevertheless, subgroup analyses appeared to be more relevant for decision making: among patients with a high-intermediate risk according to the age-adjusted International Prognostic Index (IPI), HDT yielded a significantly higher 5-year OS than CHOP (74% vs 44%; p = 0.001). Among these patients, the mean censured OS survival, adjusted for time discounting and quality of life (QOL), increased with HDT by 1.20 years (95% CI 1.19, 1.21). The cost per life-year saved with HDT was estimated as euro34 315 (95% CI 32 683, 35 947) in this subgroup. Results suggested that HDT with PBSCT support might be considered a cost-effective strategy among patients with high-intermediate-risk NHL according to the age-adjusted IPI. Its place and its cost effectiveness potential versus, or in combination with, rituximab still need further research.

ABSTRACT

OBJECTIVE: The aim of this study was to measure the impact of hospitalisation on hypnotic and anxiolytic (HA) drug prescription, during and after hospitalisation. METHOD: A descriptive study was carried out over three periods: before, during and after hospitalisation (three-month follow-up), examining the presence or absence of HA treatment at each stage. The HA drug list studied was selected using the World Health Organisation (WHO) Anatomical Therapeutic and Chemical (ATC) classification system. Trained final-year pharmacy students asked a series of structured questions during hospitalisation and postal questionnaires were sent to included patients one and three months after discharge. All the in-patient departments in the University Hospital of Besançon-France-were included, except units with pre-, peri-, and post-operative HA treatments. All in-patients present in the selected units on February 12, 2003, aged over 18, who gave their consent and were considered able to answer by the nursing team, were finally included. MAIN OUTCOME MEASURE: An eight-branch descriptive model, including the three study periods with two states (presence or absence of HA treatment) at each stage. RESULTS: A total of 260 in-patients were included, and a further 112 (43%) completed the whole study (alive, non re-hospitalised, one- and three- months post discharge response). 48% (n = 260), 64% (n = 260) and 58% (n = 112) of the included patients had sleep disorder complaints respectively before, during and after hospitalisation. HA usage increased when comparing pre- and during hospitalisation (33% vs. 51%; n = 112; p < 0.0001) and decreased when comparing during hospitalisation and post-discharge (51% vs. 43%; n = 112; p < 0.0001). The descriptive model showed an overall persistence of treatment induced by hospital stay in 5.35% of the patients. CONCLUSION: Hospital appeared to have a significant impact on delayed HA use in the French general population. Our results should incite hospital prescribers to transversally reconsider the whole sleep disorder treatment strategy in hospital settings, from improving patient's accommodation conditions, to working out a consensus on the justification of prescription of HA and precising the exact place of nursing team in sleep disorders management.

ABSTRACT

The confrontation of the macro- and micro-economic approaches of hospital costs is a recurrent question, in particular for pathologies where length of stay is highly variable, like acute myeloid leukemias (AML). This monocentric and retrospective study compares direct hospital medical costs of induction and relapse treatment sequences for AML, valued according to four different approaches: the analytic accounting system of our hospital, the French Diagnosis Related Group (DRG) cost databases of hospital discharges (readjusted, or not, to actual hospital stay duration), and official tariffs from the new French DRG prospective payment system. The average cost of hospital AML care valued by the analytic accounting system of our hospital is 61,248 euros for the induction phase and 91,702 euros for the relapse phase. All other national valuation methods result in a two- to four-fold underestimation of these costs. Even though AMLs are now individualized in the 10th version of the French diagnosis related group (DRG) classification, the impact of this issue in other pathologies is going to increase with the gradual implementation of the French DRG prospective payment system. That is why it must be assessed before the progressive extension of this financing system.

ABSTRACT

INTRODUCTION: Anaemia is a common toxicity in cancer patients and epoetins (EPOs) are now an established treatment. The economic profile of EPO treatment was assessed in patients with breast cancer treated by adjuvant-chemotherapy. MATERIALS AND METHODS: Two strategies were compared: without treatment by EPO and with the possible use of treatment by EPO (epoetin alfa) when required. The clinical effectiveness criterion was time adjusted to quality of life and economic data included only direct medical costs. MAIN RESULTS: One hundred ninety-two patients were included. In the group with the strategy containing the possible use of EPO, 45.5% of patients effectively received EPO. A significant difference in the haemoglobin level profile over time was observed which provided a significant overall benefit of 0.0052 (p<10(-4)) quality-adjusted life year (QALY) associated with an extra cost of 1,615 (p<10(-4)). In the base case analysis, the cost per added QALY was estimated as 310,577 with the strategy containing the possible use of EPO. CONCLUSION: This robust result seems to be unacceptable, but the only relevant point of discussion might be the level of acceptable incremental cost-effectiveness ratio (ICER) for a patient.

ABSTRACT

OBJECTIVE: The cardiotoxicity of anthracyclines remains a key problem in patients with aggressive non-Hodgkin's lymphoma (NHL). With regard to the actual long-term prognosis of aggressive NHL, the development of cardioprotective strategies is mandatory for these patients. A cost-effectiveness analysis was carried out to determine the potential economic profile of dexrazoxane or liposome-encapsulated doxorubicin in patients with aggressive NHL treated with a CHOP regimen (cyclophosphamide, doxorubicin, vincristine, prednisone) as first-line therapy. METHODS: A decision-analysis model described clinical events and economic consequences for theoretical patients who were to receive eight consecutive cycles of a CHOP regimen containing 50 mg/m(2) of doxorubicin as first-line chemotherapy. The timeframe of the model was the patient's lifetime. The probabilities were related to the cumulative dose of doxorubicin and age. The study was carried out from the perspective of the French healthcare system. Patients entered the model at 'choose' node: no cardioprotection versus cardioprotection with dexrazoxane or liposome-encapsulated doxorubicin. The model was based on a retrospective epidemiological study and on published data. The clinical end-point was life expectancy. Direct medical costs related to the cardioprotection and the treatment of congestive heart failure were considered. Monetary values for French prices in the year 2002 were used. Several univariate sensitivity analyses were carried out with varying clinical and economic parameters. RESULTS: Per 100 patients, the two cardioprotective strategies provided similar benefits that were estimated as 24.5 and 13.4 life-years in 60- and 40-year-old patients, respectively. The cost per life-year saved with dexrazoxane was estimated as euro6931 and euro15 599 in 60- and 40-year-old patients, respectively, and euro22 940 and euro44 982, respectively, with liposome-encapsulated doxorubicin. Several sensitivity analyses showed the robustness of the model. CONCLUSION: The results suggest the potential clinical and economic usefulness of cardioprotective therapies in patients with aggressive NHL. Prospective studies are needed to confirm these findings.
