Impact of pharmaceutical intervention on quality of life and coping strategies in patients with haematological malignancies.

OBJECTIVES: We conducted a prospective study approved by the local ethics committee to determine the impact of a pharmaceutical intervention (PI) on pain, fatigue, quality of life (QoL) and coping strategies in patients with HMs starting chemotherapy sessions. MATERIAL AND METHODS: Patients received either usual care (UC)+PI (PI group) or UC alone (UC group). They had to complete 2 questionnaires, QLQ-C30 and MAC 21, at 3 different time points: before starting the 1st chemotherapy session (T1), during the intercure (T2) and the day before starting the 2nd chemotherapy session (T3). To determine predictive factors of pain, fatigue, QoL and coping scores at T3, a multivariate ANOVA was used. QoL and coping scores were analysed longitudinally using a linear mixed model. RESULTS: Sixty-eight patients were included in the PI (n=34) or UC groups (n=34). Ninety-two percent of the patients returned all the questionnaires. At inclusion, QoL was significantly better in the PI group (P=0.047). At T3, the group had no influence on pain, fatigue, nor coping scores but a trend towards a better QoL was observed in the PI group (P=0.090). Longitudinally, the PI group did not present significantly better scores on pain, fatigue but both a trend toward better Qol scores and lower anxious preoccupations scores. CONCLUSION: A PI at the beginning of chemotherapy sessions did not have any significant impact on pain and fatigue but a trend towards better Qol scores and lower anxious preoccupations scores.

Transarterial chemoembolization for hepatocellular carcinoma: An old method, now flavor of the day.

Transarterial chemoembolization (TACE) is the recommended treatment for patients suffering from intermediate, B stage, hepatocellular carcinoma. Despite an undisputed pharmacokinetic advantage, TACE with microspheres has not been shown to be superior in terms of survival compared to conventional TACE using Lipiodol(®). The best guarantee to reduce toxicity and maximize the efficacy of TACE is to strictly observe the contraindications for the procedure (Child-Pugh>B8, reduced portal flow, very large tumor, any technical contraindication and renal impairment), and rigorous application of the administration requirements for the Lipiodol(®) emulsion or loaded microspheres (assessment of hepatic vascularization investigating for accessory vascularization, injection methods). Tumor response should be assessed after four weeks by CT or MRI using the modified RECIST criteria.

A retrospective study of the prescribing and outcomes of tyrosine kinase inhibitors in chronic myeloid leukaemia over a period of more than 10 years.

WHAT IS KNOWN AND OBJECTIVE: Since their introduction, tyrosine kinase inhibitors (TKIs) have been increasingly used in clinical practice. We describe the prescribing and the clinical and biological consequences of two such inhibitors, imatinib and erlotinib, in patients with chronic myeloid leukaemia (CML) in a practice setting over a period of more than 10 years. METHODS: All patients who received at least one TKI for chronic phase CML between 2001 and 2012 in our university hospital were included in the study. RESULTS AND DISCUSSION: Of the 139 patients, with a median age of 57 years, who were surveyed, imatinib and nilotinib were prescribed as the first TKI in 131 (94%) and 8 (6%) patients, respectively. With a median follow-up of 6 years, 342 treatment modifications were observed: 113 (33%) increased doses, 109 (32%) decreased doses, 89 (26%) TKI changes, 14 (4%) definitive discontinuations, 13 (4%) temporary discontinuations and 4 (1%) additions of IFN-α. The main reasons for the 342 treatment modifications were adverse events (n = 112, 33%), long-term optimal response (n = 58, 17%) and failure (n = 57, 17%). Eighty-five (61%), 31 (22%), 18 (13%) and 5 (4%) patients had no, 1, 2 and 3 TKI changes, respectively. Imatinib was the most prescribed TKI (75%). Adverse events resulting in treatment modifications occurred in 18% of patients for imatinib, 49% for nilotinib and 41% for dasatinib (P < 0·001). Median time to TKI change whatever the reason was >50 months (not achieved) for imatinib, 22 months for nilotinib and 27 months for dasatinib (log-rank test, P < 0·001). WHAT IS NEW AND CONCLUSION: Imatinib was the most prescribed TKI both in the first and in subsequent therapeutic lines for chronic phase CML. Our study showed a very good efficacy-safety profile for imatinib at a median follow-up of 6 years in an unselected French population.

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.

Generic vancomycin products: Analysis of serum concentrations in patients with acute myeloid leukemia.

UNLABELLED: Concerns have recently emerged about the quality of generic vancomycin products. Our aim is to analyze serum vancomycin concentrations measured 48 hours after the start of an empirical treatment regimen in patients with acute myeloid leukemia (AML) who received one of the two generic vancomycin products available in France. PATIENTS AND METHODS: Seventy-nine AML patients treated with vancomycin during two study periods were included in the study. Our vancomycin dosing regimen was based on the patients' total body weight adjusted for renal clearance. RESULTS: A total of 93 serum vancomycin concentrations were collected: 31 in period 1 and 62 in period 2. In bivariate analysis, the mean serum vancomycin concentrations were not significantly different (19.9 ± 11.2 mg/L in period 1 vs 18.9 ± 6.0 mg/L in period 2, P=0.64). In the final generalized estimating equations model, serum vancomycin concentrations correlated statistically with a positive coefficient for age (P<0.001) and with negative coefficients for male sex (P=0.001) and hemoglobin level (P=0.021). CONCLUSION: Serum vancomycin concentrations measured 48 hours after the start of an empirical treatment were not influenced by the nature of the generic product but correlated with age, sex and hemoglobin level in AML patients.

Idarubicin-loaded beads for chemoembolisation of hepatocellular carcinoma: results of the IDASPHERE phase I trial.

BACKGROUND: A phase I dose-escalation trial of transarterial chemoembolisation (TACE) with idarubicin-loaded beads was performed in cirrhotic patients with hepatocellular carcinoma (HCC). AIM: To estimate the maximum-tolerated dose (MTD) and to assess safety, efficacy, pharmacokinetics and quality of life. METHODS: Patients received a single TACE session with injection of 2 mL drug-eluting beads (DEBs; DC Bead 300-500 µm) loaded with idarubicin. The idarubicin dose was escalated according to a modified continuous reassessment method. MTD was defined as the dose level closest to that causing dose-limiting toxicity (DLT) in 20% of patients. RESULTS: Twenty-one patients were enrolled, including nine patients at 5 mg, six patients at 10 mg, and six patients at 15 mg. One patient at each dose level experienced DLT (acute myocardial infarction, hyperbilirubinaemia and elevated aspartate aminotransferase (AST) at 5-, 10- and 15-mg, respectively). The calculated MTD of idarubicin was 10 mg. The most frequent grade ≥3 adverse events were pain, elevated AST, elevated γ-glutamyltranspeptidase and thrombocytopenia. At 2 months, the objective response rate was 52% (complete response, 28%, and partial response, 24%) by modified Response Evaluation Criteria in Solid Tumours. The median time to progression was 12.1 months (95% CI 7.4 months--not reached); the median overall survival was 24.5 months (95% CI 14.7 months--not reached). Pharmacokinetic analysis demonstrated the ability of DEBs to release idarubicin slowly. CONCLUSIONS: Using drug-eluting beads, the maximum-tolerated dose of idarubicin was 10 mg per TACE session. Encouraging responses and median time to progression were observed. Further clinical investigations are warranted (NCT01040559).

Result and cost of hepatic chemoembolisation with drug eluting beads in 21 patients.

PURPOSE: The aim of our study was to assess the results and cost of a treatment strategy involving transarterial chemoembolisation with drug eluting beads (DEB-TACE) in patients with unresectable non-metastatic hepatocellular carcinoma (HCC). PATIENTS AND METHODS: This study included all patients treated with DEB-TACE in our hospital between January 2009 and December 2010. All patients received DEB-TACE on demand and were evaluated after each session. RESULTS: Twenty-one patients received an average of 1.3 sessions. The median time to treatment discontinuation and median progression-free survival was 181 days and 295 days, respectively. Toxicity caused treatment discontinuation in three patients (14%). For the hospital, the average direct cost of treatment was €6,033 according to the analytical accounting system vs. €4,558 according to the official tariffs from the new French Diagnosis-Related Group prospective payment system (P=0.002). CONCLUSION: In the treatment of HCC, on-demand DEB-TACE stabilises the disease in some patients but has not yet been thoroughly evaluated.

[Thalidomide with or without dexamethasone for refractory multiple myeloma]. / Intérêt du thalidomide avec ou sans dexaméthasone dans le myélome multiple réfractaire.

It was shown in 1999 thalidomide could induce a therapeutic response in patients with refractory multiple myeloma. Between March 2000 and January 2002, we treated 21 patients with refractory multiple myeloma with thalidomide (Thalidomide) at initial dose of 400 mg a day. Response rate (Intergroupe Francophone du Myélome criteria) was 33 percent and median progression-free survival estimated to 15 months. All patients suffered from drowsiness and constipation requiring lowest doses. Five patients developed a sensitive neuropathy. Eight refractory patients were treated by a combination of their prior maximally tolerated dose of thalidomide and monthly dexamethasone (Soludécadron) alone (n = 4) or associated to cyclophosphamide (Endoxan) and étoposide (Etopophos) (n = 4). Six patients on 8 were responders. Our results suggest that the combination thalidomide/dexamethasone should be compared to thalidomide alone in a prospective, randomized study in patients with refractory multiple myeloma.
