Merkel cell carcinoma (MCC) is a rare and highly malignant skin cancer with neuroendocrine differentiation. We studied the potential value of 18FDG PET in the management of MCC. Eleven patients with MCC were examined by 18FDG PET and PET-CT for staging purpose (n=4) or for detection of recurrence (n=7). Qualitative and quantitative interpretation of PET studies was performed routinely. 18FDG PET observations were compared to clinical and radiological findings. In 6 patients, PET findings were also compared to histology. In 7 patients, the 18FDG tumor uptake was compared to the MCC proliferative activity expressed by the Ki-67 index. 18FDG PET was contributive in 10/11 MCC patients. In 7 patients, 18FDG PET detected focal lesions or a disseminated stage of the disease including dermal, nodal and visceral metastases. In 3 patients, a normal 18FDG PET confirmed complete remission of disease. Most MCC patients exhibited highly 18FDG-avid sites suggestive of increased glucose metabolism. This imaging pattern was related to a high proliferative activity (Ki-67 index >50%). In 1 patient with a weakly proliferative nodal MCC (Ki-67<10%), a false negative result was yielded by metabolic imaging. In 4/11 patients, 18FDG PET revealed an unsuspected second neoplasm in addition to MCC. It is concluded that whole-body 18FDG PET may be useful in the management of MCC patients. However, a normal 18FDG PET aspect cannot rule out MCC with low proliferative activity. [less ▲]

The Clinical and Angiographic analysis with a Cobalt Alloy Coronary Stent (Driver) (CLASS) study was a prospective, nonrandomized, multicenter study designed to assess the safety and efficacy of a cobalt-chromium alloy-based stent in patients with stable or unstable angina pectoris. A total of 203 lesions were treated in 202 enrolled patients. The percentage of major adverse cardiac event-free patients was 87.6% (177 of 202) at 6 months (primary safety end point; major adverse cardiac events were defined as death, myocardial infarction, emergency bypass surgery, or target lesion revascularization [percutaneous transluminal coronary angioplasty or coronary artery bypass grafting]). The angiographic success rate (primary efficacy end point) was 100%, and the procedural success rate was 98%. The binary in-stent restenosis rate at 6 months was 12.6%. Our results have demonstrated that the Driver cobalt-chromium alloy stent can be used with a low 6-month incidence of major adverse cardiac events, a low 6-month binary restenosis rate, and high angiographic and procedural success rates.

We examined the influence of vessel size using an intention-to-treat approach in 259 patients who underwent stent implantation and in 257 patients who underwent balloon angioplasty alone in the BENESTENT trial. In the stented population, smaller vessel size was associated with a higher stent:vessel ratio, a greater relative gain and a greater subsequent loss index, and a higher risk of adverse cardiac events. In the balloon angioplasty population small vessel size conveyed an increased requirement for revascularization but did not increase the risk of procedural failure or myocardial infarction during follow-up. Logistic regression indicated that decreasing vessel size (as a continous variable) was associated with an increasing risk of a cardiac event for both the stent and balloon angioplasty populations.

OBJECTIVES: This study aims to estimate the clinical and economic burden of non-adherence with oral bisphosphonates in osteoporotic patients and the potential cost-effectiveness of adherence-enhancing interventions. METHODS: A validated Markov microsimulation model estimated costs and outcomes (i.e. the number of fractures and the quality-adjusted life-year (QALY)) for three adherence scenarios: no treatment, real-world adherence and full adherence over 3 years. The real-world adherence scenario employed data from a published observational study. The incremental cost per QALY gained was estimated and compared across the three adherence scenarios. RESULTS: The number of fractures prevented and the QALY gain obtained at real-world adherence levels represented only 38.2% and 40.7% of those expected with full adherence, respectively. The cost per QALY gained of real-world adherence compared with no treatment was estimated at euro10279, and full adherence was found to be cost-saving compared with real-world adherence. CONCLUSIONS: This study suggests that more than half of the potential clinical benefits from oral bisphosphonates in patients with osteoporosis are lost due to poor adherence with treatment. Depending on their cost, interventions with improved adherence to therapy have the potential to be an attractive use of resources. [less ▲]

OBJECTIVES: Medication nonadherence is common for osteoporosis, but its consequences have not been well described. This study aimed to quantify the clinical and economic impacts of poor adherence and to evaluate the potential cost-effectiveness of improving patient adherence by using hypothetical behavioral interventions. METHODS: A previously validated Markov microsimulation model was adapted to the Irish setting to estimate lifetime costs and outcomes (fractures and quality-adjusted life-year [QALY]) for three adherence scenarios: no treatment, real-world adherence, and full adherence over 3 years. The real-world scenario employed adherence and persistence data from the Irish Health Services Executive-Primary Care Reimbursement Services pharmacy claims database. We also investigated the cost-effectiveness of hypothetical behavioral interventions to improve medication adherence (according to their cost and effect on adherence). RESULTS: The number of fractures prevented and the QALY gain obtained at real-world adherence levels represented only 57% and 56% of those expected with full adherence, respectively. The costs per QALY gained of real-world adherence and of full adherence compared with no treatment were estimated at euro 11,834 and euro 6,341, respectively. An intervention to improve adherence by 25% would result in an incremental cost-effectiveness ratio of euro 11,511 per QALY and euro 54,182 per QALY, compared with real-world adherence, if the intervention cost an additional euro 50 and euro 100 per year, respectively. DISCUSSION: Poor adherence with osteoporosis medications results in around a 50% reduction in the potential benefits observed in clinical trials and a doubling of the cost per QALY gained from these medications. Depending on their costs and outcomes, programs to improve adherence have the potential to be an efficient use of resources. [less ▲]

BACKGROUND: Our aims were to compare coronary artery bypass grafting (CABG) and stenting for the treatment of diabetic patients with multivessel coronary disease enrolled in the Arterial Revascularization Therapy Study (ARTS) trial and to determine the costs of these 2 treatment strategies. METHODS AND RESULTS: Patients (n=1205) were randomly assigned to stent implantation (n=600; diabetic, 112) or CABG (n=605; diabetic, 96). Costs per patient were calculated as the product of each patient's use of resources and the corresponding unit costs. Baseline characteristics were similar between the groups. At 1 year, diabetic patients treated with stenting had the lowest event-free survival rate (63.4%) because of a higher incidence of repeat revascularization compared with both diabetic patients treated with CABG (84.4%, P<0.001) and nondiabetic patients treated with stents (76.2%, P=0.04). Conversely, diabetic and nondiabetic patients experienced similar 1-year event-free survival rates when treated with CABG (84.4% and 88.4%). The total 1-year costs for stenting and CABG in diabetic patients were $12 855 and $16 585 (P<0.001) and in the nondiabetic groups, $10 164 for stenting and $13 082 for surgery. CONCLUSIONS: Multivessel diabetic patients treated with stenting had a worse 1-year outcome than patients assigned to CABG or nondiabetics treated with stenting. The strategy of stenting was less costly than CABG, however, regardless of diabetic status. [less ▲]
