RESUMO
BACKGROUND: Few studies have estimated the real-world economic burden such as all-cause and follicular lymphoma (FL)-related costs and health care resource utilization (HCRU) in patients with FL. OBJECTIVES: This study evaluated outcomes in patients who were newly initiated with FL indicated regimens by line of therapy with real-world data. METHODS: A retrospective study was conducted among patients with FL from MarketScan® databases between January 1, 2010 and December 31, 2013. Patients were selected if they were ≥18 years old when initiated on a FL indicated therapy, had at least 1 FL-related diagnosis, ≥1 FL commonly prescribed systemic anti-cancer therapy after diagnosis, and did not use any FL indicated regimen in the 24 months prior to the first agent. These patients were followed up at least 48 months and the outcomes, including the distribution of regimens by line of therapy, the treatment duration by line of therapy, all-cause and FL-related costs, and HCRU by line of therapy were evaluated. RESULTS: This study identified 598 patients who initiated FL indicated treatment. The average follow-up time was approximately 5.7 years. Of these patients, 50.2% (n=300) were female, with a mean age of 60.7 years (SD=13.1 years) when initiating their treatment with FL indicated regimens. Overall, 598 (100%) patients received first-line therapy, 180 (43.6%) received second-line therapy, 51 received third-line therapy, 21 received fourth-line therapy, and 10 received fifth-line therapy. Duration of treatment by each line of therapy was 370 days, 392 days, 162 days, 148 days, and 88 days, respectively. The most common first-line regimens received by patients were rituximab (n=201, 33.6%), R-CHOP (combination of rituximab, cyclophosphamide, doxorubicin hydrochloride [hydroxydaunomycin]; n=143, 24.0%), BR (combination of bendamustine and rituximab; n=143, 24.0%), and R-CVP (combination of rituximab, cyclophosphamide, vincristine, and prednisone; n=71, 11.9%). The most common second-line treatment regimens were (N=180): rituximab (n=78, 43.3%) and BR (n=41, 22.8%). Annualized all-cause health care costs per patient ranged from US$97 141 (SD: US$144 730) for first-line to US$424 758 (SD: US$715 028) for fifth-line therapy. CONCLUSIONS: The primary regimens used across treatment lines conform to those recommended by the National Comprehensive Cancer Network clinical practice guidelines. The economic burden for patients with FL is high and grows with subsequent lines of therapy.
RESUMO
AIMS: The Endeavor zotarolimus-eluting coronary stent has been shown to reduce the restenosis rate compared to bare metal stents and has impacted other clinical measures such as mortality, acute myocardial infarctions (AMI) and target vessel revascularisation (TVR). METHODS AND RESULTS: Using pooled efficacy data from the Endeavor clinical trial programme, a model was developed to compare the cost effectiveness of the Endeavor drug eluting stent (DES) with the Driver bare meal stent (BMS) over a four year time period. Endeavor was more costly but had an improved clinical outcome compared to Driver BMS over four years with a 4% reduction in deaths, 33% reduction in AMI and a 45% reduction in TVR. Late stent thrombosis was the only event showing an increased incidence for Endeavor of 0.2% compared to 0% for Driver. The incremental cost effectiveness ratio was pound3,757/quality adjusted life years (QALY). CONCLUSIONS: Although much controversy has surrounded the appropriate way to assess the cost effectiveness of DES technology, a comprehensive analysis is presented and this suggests that by using extended clinical trial data out to four years, the Endeavor DES in particular, but DES technologies in general, are cost-effective approaches to percutaneous coronary intervention.
