Clinical and economic impact of drug eluting beads in transarterial chemoembolization for hepatocellular carcinoma.

WHAT IS KNOWN AND OBJECTIVE: Drug eluting beads (DEBs) theoretically improve the efficacy and safety of transarterial chemoembolization (TACE) in hepatocellular carcinoma (HCC). Nonetheless, their economic profile has not been assessed. Our retrospective before/after study aimed to compare efficacy, safety and economic profile of two strategies of TACE without (Period 1) or with the possibility of using DEBs (Period 2). METHODS: All HCC patients treated by TACE in our hospital between March 2006 and May 2013 were included. Economic analyses were performed from the French Public Health Insurance point of view according to the French Diagnosis-Related Group prospective payment system and from the analytic accountability. RESULTS AND DISCUSSION: One hundred and sixty-one patients were included. Median time to treatment failure and overall survival were 13.1 and 23.8 months in Period 1 vs. 14.1 and 30.2 months in Period 2 (P = 0.45 and P = 0.40). Mean hospital durations and tariffs were 14.9 ± 7.7 days and € 11 472 ± 5901 in Period 1 vs. 12.4 ± 8.4 days and € 7654 ± 4625 in Period 2 (P = 0.03 and P < 10(-4) ). WHAT IS NEW AND CONCLUSION: The possibility of using DEBs did not improve the prognosis in HCC patients treated by TACE. Nonetheless, it had a better medico-economic profile.

Effects of glycosylated recombinant human granulocyte colony-stimulating factor after high-dose cytarabine-based induction chemotherapy for adult acute myeloid leukaemia.

The Australian Leukaemia Study Group (ALSG) investigated whether G-CSF would accelerate haemopoietic recovery after induction treatment for acute myeloid leukaemia (AML) intensified with high-dose cytarabine, and therefore improve response rates and survival. Patients were randomised to receive lenograstim (glycosylated recombinant human G-CSF) 5 microg per kg body weight subcutaneously daily from day 8 after starting chemotherapy, or no cytokine, following chemotherapy with cytarabine 3 g/m2 every 12 h on days 1, 3, 5, and 7, together with idarubicin 9 or 12 mg/m2 on days 1, 2, and 3, plus etoposide 75 mg/m2 on days 1 to 7 inclusive. Patients had untreated AML, and were aged 16 to 60 years. Overall, 54 evaluable patients were randomised to receive lenograstim and 58 to no cytokine. Patients in the lenograstim arm had a significantly shorter duration of neutropenia <0.5 x 10(9)/l compared to patients in the no cytokine arm (median 18 vs 22 days; P = 0.0005), and also shorter duration of total leucopenia <1.0 x 10(9)/l (17 vs 19 days; P = 0.0002), as well as a reduction in duration of treatment with therapeutic intravenous antibiotics (20 vs 24 days; P= 0.015) and a trend to reduced number of days with fever >38.0 degrees C (9 vs 12 days; P = 0.18). There were no differences between the two groups in platelet recovery, red cell or platelet transfusions, or non-haematological toxicities. For patients achieving CR after their first induction course, a reduction in the time to the start of the next course of therapy was observed in the lenograstim arm, from a median of 40.5 days to a median of 36 days (P = 0.082). The overall complete response rates to chemotherapy were similar, 81% in the lenograstim arm vs 75% for the no cytokine arm (P = 0.5), and there was no significant difference in the survival durations. We conclude that the granulopoietic stimulating effect of G-CSF is observed after induction therapy for AML intensified by high-dose cytarabine, resulting in an improvement in a number of clinically important parameters with no major adverse effects.

Idarubicin: a pharmacoeconomic evaluation of its use in adult patients with acute myeloid leukaemia.

Idarubicin is an effective agent in the treatment of acute myeloid leukaemia (AML), inducing complete remission in 39 to 80% of newly diagnosed patients. Although it also demonstrates efficacy as monotherapy, and is of use in relapsed or refractory disease, most comparative clinical trials have administered idarubicin intravenously in combination with cytarabine in newly diagnosed patients. These trials indicate that improved survival and response rates, and rapid achievement of remission, are more likely with idarubicin than with daunorubicin, when both agents are given in combination with cytarabine. In elderly patients, however, response rates are lower than in younger patients, and there is less disparity in efficacy between idarubicin and daunorubicin induction therapy. Although AML is an expensive disease to treat, the majority of costs are associated with the length of hospitalisation, with the acquisition cost of the chemotherapy agents contributing less than 10% to overall expenditure. Idarubicin combined with cytarabine therapy achieved higher response rates with the first cycle of therapy than daunorubicin, thereby reducing the requirements for a second cycle of therapy and further hospitalisation. Compared with daunorubicin plus cytarabine induction treatment, idarubicin plus cytarabine reduced the costs of achieving a complete response by between 22 and 39% in patients with a median age less than 60 years. In patients with a median age of 62 years, who are more representative of the AML population, costs of achieving a complete response were reduced by 3 to 6%. Thus, idarubicin is more cost effective than daunorubicin as induction therapy in combination with cytarabine, in adult patients with AML. The pharmacoeconomic position of idarubicin in postinduction therapy remains to be established.
