Objectives: A systematic review/meta-analysis was conducted to assess the effectiveness and safety of second-line treatments for advanced renal cell carcinoma (RCC), which includes the vascular endothelial growth factor inhibitor axitinib.

Methods: Database searches were conducted to identify randomised controlled trials (RCTs). Indirect comparisons using a fixed-effect Bayesian model were used to assess the relative effectiveness of treatments and reported as hazard ratio (HR) and 95% credible intervals (CrI).

Background: Chronic myeloid leukemia (CML) is a myeloproliferative disorder of blood stem cells. The tyrosine kinase inhibitor (TKI) imatinib was the first targeted therapy licensed for patients with chronic-phase CML, and its introduction was associated with substantial improvements in response and survival compared with previous therapies. Clinical trial data are now available for the second-generation TKIs (nilotinib, dasatinib, and bosutinib) in the first-, second-, and third-line settings.

Aims: The most effective sequence of tamoxifen and both steroidal (SAIs) and non-steroidal aromatase inhibitors (NSAIs) has been extensively studied in the adjuvant setting. However, treatments for women who have failed initial aromatase inhibitor therapy in the metastatic setting have received relatively little attention. A systematic review was undertaken to assess the use of SAIs and NSAIs in metastatic breast cancer.

Objective: To evaluate the cost effectiveness of long-term ezetimibe monotherapy in patients with established cardiovascular disease (CVD) who do not tolerate statins or in whom they are contraindicated.

Methods: A Markov model was used to estimate the potential costs and benefits associated with ezetimibe monotherapy compared with no treatment. The benefits associated with ezetimibe treatment were informed by a systematic review of clinical evidence and a published relationship linking changes in low-density lipoprotein cholesterol (LDL-C) levels to cardiovascular events.

Objectives: To study the evidence on the efficacy and safety of ezetimibe monotherapy for the treatment of primary (heterozygous familial and non-familial) hypercholesterolaemia.

Design: Systematic review and meta-analysis of randomized controlled trials (RCTs).

Methods: Eleven electronic bibliographic databases covering the biomedical, scientific and grey literature were searched from inception and supplemented by contact with experts in the field.

Background: Ezetimibe has been reported to improve lipid control in patients with established cardiovascular disease (CVD).

Objective: The aim of this study was to estimate the potential long-term impact on health status of prescribing ezetimibe in combination with statin therapy in patients with established CVD and evaluate its cost-effectiveness in a health economic model.

Methods: A Markov model was used to compare ezetimibe and statin combination therapy with statin monotherapy.

Objectives: To review the clinical and cost-effectiveness of ezetimibe as a combination therapy or monotherapy for the treatment of primary hypercholesterolaemia in the UK.

Data Sources: Twelve electronic databases were searched from inception to June 2006. Searches were supplemented by hand-searching relevant articles, sponsor and other submissions of evidence to the National Institute of Health and Clinical Excellence and conference proceedings.

Objectives: To evaluate three technologies for the management of advanced colorectal cancer: (1) first-line irinotecan combination [with 5-fluorouracil (5-FU)] or second-line monotherapy; (2) first- or second-line oxaliplatin combination (again, with 5-FU); and (3) raltitrexed, where 5-FU is inappropriate. To examine the role of irinotecan and oxaliplatin in reducing the extent of incurable disease before curative surgery (downstaging).

Sources: Ten electronic bibliographic databases covering the period up to August 2004.

Background: Computer-guided therapy is an innovative treatment strategy that could have an important role in the future of psychological treatment. This paper summarises the available published evidence that assesses the effectiveness of a computerised cognitive behaviour therapy (CCBT) for obsessive-compulsive disorder (OCD).

Methods: Fifteen electronic bibliographic databases including Medline, Embase, the Cochrane Library, Cinahl, PsycINFO, Biological Abstracts, HMIC and NHS CRD databases were comprehensively searched in March 2004: ['obsessive compulsive disorder' (text and indexed terms)] AND ['cognitive therapy' (text and indexed terms)] AND ['computer' (text and indexed terms)].
