[Economic impact of transarterial chemoembolization with drug eluting beads in the treatment of hepatocellular carcinoma]. / Impact économique de la chimioembolisation avec microsphères chargées dans le traitement du carcinome hépatocellulaire.

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.

Trends in the incidence and management of biliary tract cancer: a French population-based study.

BACKGROUND & AIMS: The trends in incidence and management of biliary tract cancer (BTC) were investigated in a well-defined French population over a 30-year period (1976-2005). METHODS: Data were obtained from the Burgundy digestive cancer registry. Age-standardised incidence rates and trends in incidence were determined. Treatment and stage at diagnosis were also investigated. Five-year survival rates were calculated. RESULTS: Six hundred and fifteen cases of BTC were recorded. There was no significant change in BTC incidence over the 30-year period. For extrahepatic BTC age-standardised incidence rates were 1.1/100,000 for 1976-80 and 2001-2005. These rates were respectively 0.3 and 0.2/100,000 for intrahepatic BTC. The proportion of patients undergoing resection for cure increased over time from 4.8% to 14.2% (p<0.001). The proportion of stage I-II cases ranged from 3.2% to 7.1% but did not vary significantly over time (p=0.55). Most cases were metastatic or unresectable at diagnosis. Five-year relative survival rates were 4.5% for 1976-85 and 6.7% for 1996-2005, ranging from 35.1% for stages I-II to 4.3% for advanced BTC. Age and stage at diagnosis were independent prognostic factors. CONCLUSIONS: The incidence of BTC has remained stable in Burgundy over the past 30 years. BTC prognosis remains poor and has only improved slightly over time.

Estimating the cost related to surveillance of colorectal cancer in a French population.

Little is known about costs related to the surveillance of patients that have undergone curative resection of colorectal cancer. The aim of this study was to calculate the observed surveillance costs for 385 patients followed-up over a 3-year period, to estimate surveillance costs if French guidelines are respected, and to identify the determinants related to surveillance costs to derive a global estimation for France, using a linear mixed model. The observed mean surveillance cost was 713. If French recommendations were strictly applied, the estimated mean cost would vary between 680 and 1,069 according to the frequency of abdominal ultrasound. The predicted determinants of cost were: age, recurrence, duration of surveillance since diagnosis, and adjuvant treatments. For France, the surveillance cost represented 4.4% of the cost of colorectal cancer management. The cost of surveillance should now be balanced with its effectiveness and compared with surveillance alternatives.

Cost-effectiveness analysis of first-line chemotherapies in metastatic colorectal cancer. Results of the Fédération Francophone de Cancérologie Digestive (FFCD) 9601 randomized trial.

BACKGROUND: The De Gramont regimen (or high-dose LV5FU2, HD-LV5FU2) is considered a standard treatment for metastatic colorectal cancer. The aim of the study was to evaluate the efficacy and the costs of three regimens as compared to HD-LV5FU2: raltitrexed (R), LV5FU2 with a lower dose of folinic acid (LD-LV5FU2), and weekly infusional 5FU (WI-FU). METHODS: An economic analysis was performed prospectively as part of a randomized trial comparing first-line chemotherapy regimens in 294 patients with unresectable metastatic colorectal cancer. The primary endpoint was event-free survival (EFS). Direct medical costs were computed from the health system viewpoint using 2001 unit costs. RESULTS: None of the three regimens improved EFS as compared to HD-LV5FU2. R was less effective and more toxic. The mean total cost per patient was euro 15,970 for HD-LV5FU2. The cost of R (10,687 euro) was lower than that of HD-LV5FU2 (p = 0.008). The cost of LD-LV5FU2 (14,888 euro) and of WI-FU (13,760 euro) was not significantly different from that of HD-LV5FU2. CONCLUSION: The lower efficacy and increased toxicity of R made it a clinically inferior regimen despite its easy administration and lower cost. The HD-LV5FU2 protocol remains a better treatment. LD-LV5FU2 appeared a good alternative regimen because it reduced costs without jeopardizing its efficacy. The WI-FU regimen did not show a significant difference in terms of efficacy, but suggested toxicity to be slightly increased.

Use of a decision analysis model to assess the cost-effectiveness of 18F-FDG PET in the management of metachronous liver metastases of colorectal cancer.

UNLABELLED: Few data exist on the medicoeconomic usefulness of PET in the management of metachronous liver metastases from colorectal cancer. This study was designed to assess the cost-effectiveness of PET in the diagnosis and staging of patients with metachronous liver metastases of colorectal cancer using a decision analysis model. METHODS: Two alternatives were compared: CT and CT associated with PET (CT+PET). Transition probabilities were estimated from published data and consultations with experts. Survival data were provided by the Burgundy Digestive Cancer Registry (France). Costs of imaging techniques and treatments were assessed using reimbursements from the French health care insurance for the year 2004. Evaluation criteria included incremental cost-effectiveness ratios and the proportion of unnecessary operations avoided in patients without metachronous liver metastases. RESULTS: CT+PET was the most cost-effective strategy, presenting an expected incremental cost saving of 2,671 (approximately $3,213) per patient, for the same level of expected effectiveness as CT alone (1.88-y life expectancy per patient). Sensitivity analyses performed on epidemiologic and economic parameters showed that this model was robust. The model also suggested that CT+PET could avoid exploratory surgery for 6.1% of patients-that is, 88.4% risk reduction compared with CT alone. CONCLUSION: PET for diagnosis and staging does not generate additional survival effectiveness compared with CT alone. However cost savings associated with its use and the improvement of therapeutic management therefore justify its generalization in clinical practice.
