Is extensive screening for cancer in idiopathic venous thromboembolism warranted? J Thromb Haemost 2011; 9: 79-84.Summary. Background: Patients with a first episode of idiopathic venous thromboembolism (IVTE) have an estimated 10% incidence of cancer within 12 months after diagnosis. However, the utility of screening for cancer in this population is controversial. Methods: In this prospective concurrently controlled cohort study, limited and extensive cancer screening strategies were compared. All 630 patients underwent baseline screening consisting of history, physical examination, basic laboratory tests and chest X-ray. In the extensive screening group abdominal and chest CT scan and mammography were added. Outcomes were incidence and curability of cancer, and cancer-related and overall mortality. Results: In 12 of the 342 (3.5%) patients in the extensive screening group malignancy was diagnosed at baseline compared with 2.4% (seven of 288 patients) in the limited screening group. Extensive screening detected six additional cancers (2.0%; 95% CI, 0.74-4.3), of which three were potentially curable. During a median 2.5 years of follow-up, cancer was diagnosed in 3.7% and 5.0% in the extensive and limited screening groups, respectively. In the extensive screening group 26 patients (7.6%) died compared with 24 (8.3%) in the limited screening group; adjusted hazard ratio 1.22 (95% CI, 0.69-2.22). Of these deaths 17 (5.0%) in the extensive screening group and 8 (2.8%) in the limited screening group were cancer related; adjusted hazard ratio 1.79 (95% CI, 0.74-4.35). Conclusions: The low yield of extensive screening and lack of survival benefit do not support routine screening for cancer with abdominal and chest CT scan and mammography in patients with a first episode of IVTE.
OBJECTIVE -Cardiovascular disease (CVD) is the most important cause of mortality in patients with type 2 diabetes. We aimed to determine the effect of statin therapy versus placebo on the progression of carotid intima-media thickness (IMT) in type 2 diabetic patients without manifest CVD. RESEARCH DESIGN AND METHODS-A randomized, placebo-controlled, doubleblind clinical trial was performed in 250 patients with type 2 diabetes. Patients were given either 0.4 mg cerivastatin or placebo daily. In August 2001, when cerivastatin was withdrawn from the market, 0.4 mg cerivastatin was replaced by 20 mg simvastatin without deblinding the study. The primary end point was the change of mean common carotid IMT, as measured by B-mode ultrasound, over 2 years.RESULTS -Common carotid IMT at baseline was 0.780 mm in the placebo group and 0.763 mm in the statin group and did not change significantly after 2 years. There was no significant difference in IMT change in any carotid segment between the groups. LDL cholesterol was reduced by 25% in the statin group and increased by 8% in the placebo group (P Ͻ 0.001). Cardiovascular events occurred in 12 patients in the placebo group and two patients in the statin group (P ϭ 0.006).CONCLUSIONS -There was no effect of 2 years' statin therapy on carotid IMT in type 2 diabetic subjects. The natural history of IMT in our patients was milder than anticipated. In contrast, we observed a significantly lower cardiovascular event rate on statin therapy. Prognostic tools other than IMT should be explored in this patient group. Diabetes Care 27:2887-2892, 2004C ardiovascular disease (CVD), including cerebrovascular disease, coronary artery disease (CAD), and peripheral vascular disease, is the most important cause of mortality in patients with type 2 diabetes (1). The severity and progression of atherosclerosis can be assessed noninvasively by ultrasonographic measurements of the intima-media thickness (IMT) in the carotid and femoral arteries. Ultrasonographic IMT measurements of the far wall relate to histological IMT measurements (2). Carotid IMT correlates with prevalent CVD (3), angiographically proven coronary atherosclerosis (4), and risk factors for CVD, including LDL cholesterol (5,6). In prospective studies, carotid IMT has proven to be predictive of CVD (7-9), and as a consequence, IMT is increasingly used as an intermediate end point in clinical trials. Mean common carotid IMT in middle-aged subjects without CAD is reported to range from 0.71 to 0.91 mm in diabetic patients vs. 0.66 to 0.74 mm in control subjects (10,11). In diabetes, IMT is less consistently correlated to classical risk factors such as LDL cholesterol. Importantly, at the time our study was designed, data on the progression and predictive value of IMT in type 2 diabetes were lacking.During the last 10 years, large clinical trials have demonstrated that HMG-CoA (hydroxy-methylglutaryl coenzyme A) reductase inhibitors (statins) reduce the risk of cardiovascular events in the setting of secondary and primary preventio...
Key Points• Diagnostic management of ipsilateral recurrent DVT of the leg is complicated because residual DVT is common and mimics acute DVT on CUS.• MRDTI is able to reproducibly distinguish acute ipsilateral recurrent DVT from 6-monthold chronic residual thrombi in the leg veins.Accurate diagnostic assessment of suspected ipsilateral recurrent deep vein thrombosis (DVT) is a major clinical challenge because differentiating between acute recurrent thrombosis and residual thrombosis is difficult with compression ultrasonography (CUS). We evaluated noninvasive magnetic resonance direct thrombus imaging (MRDTI) in a prospective study of 39 patients with symptomatic recurrent ipsilateral DVT (incompressibility of a different proximal venous segment than at the prior DVT) and 42 asymptomatic patients with at least 6-month-old chronic residual thrombi and normal D-dimer levels. All patients were subjected to MRDTI. MRDTI images were judged by 2 independent radiologists blinded for the presence of acute DVT and a third in case of disagreement. The sensitivity, specificity, and interobserver reliability of MRDTI were determined. MRDTI demonstrated acute recurrent ipsilateral DVT in 37 of 39 patients and was normal in all 42 patients without symptomatic recurrent disease for a sensitivity of 95% (95% CI, 83% to 99%) and a specificity of 100% (95% CI, 92% to 100%). Interobserver agreement was excellent (k 5 0.98). MRDTI images were adequate for interpretation in 95% of the cases. MRDTI is a sensitive and reproducible method for distinguishing acute ipsilateral recurrent DVT from 6-month-old chronic residual thrombi in the leg veins. (Blood. 2014;124(4):623-627)
Objective To study whether stopping elastic compression stockings (ECS) after 12 months is non-inferior to continuing them for 24 months after proximal deep venous thrombosis.Design Multicentre single blind non-inferiority randomised controlled trial.Setting Outpatient clinics in eight teaching hospitals in the Netherlands, including one university medical centre.Participants Patients compliant with compression therapy for 12 months after symptomatic, ultrasound proven proximal deep venous thrombosis of the leg.Interventions Continuation or cessation of ECS 12 months after deep venous thrombosis.Main outcome measures The primary outcome was the incidence of post-thrombotic syndrome 24 months after diagnosis of deep venous thrombosis, as assessed by the standardised Villalta scale in an intention to treat analysis. The predefined non-inferiority margin was 10%. The main secondary outcome was quality of life (VEINES-QOL/Sym).Results 518 patients compliant with ECS and free of post-thrombotic syndrome were randomised one year after diagnosis of deep venous thrombosis to stop or continue ECS therapy for another year. In the stop-ECS group, 51 of 256 patients developed post-thrombotic syndrome, with an incidence of 19.9% (95% confidence interval 16% to 24%). In the continue-ECS group, 34 of 262 patients developed post-thrombotic syndrome (incidence 13.0%, 9.9% to 17%), of whom 85% used ECS six or seven days a week during the study period, for an absolute difference of 6.9% (95% confidence interval upper limit 12.3%). Because the upper limit of the 95% confidence interval exceeds the predefined margin of 10%, non-inferiority was not reached. The number needed to treat to prevent one case of post-thrombotic syndrome by continuing ECS was 14 (95% confidence interval lower limit 8). Quality of life did not differ between the two groups.Conclusion Stopping ECS after one year in compliant patients with proximal deep venous thrombosis seemed not to be non-inferior to continuing ECS therapy for two years in this non-inferiority trial.Trial registration Netherlands Trial Register NTR1442.
