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: The aim of this study was to measure the impact of hospitalisation on hypnotic and anxiolytic (HA) drug prescription, during and after hospitalisation.
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.
An eight-branch descriptive model, including the three study periods with two states (presence or absence of HA treatment) at each stage.
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.
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: 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.
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.
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.
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: 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: 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.
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.
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.
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.
