Background Breast cancer is the uncontrolled, abnormal growth of malignant breast tissue affecting predominantly women. Metastatic breast cancer (mBC) is an advanced stage of the disease when the disease has spread beyond the original organ. Hormone receptor status and human epidermal growth factor 2 (HER2) status are two predictive factors that are taken into consideration when estimating the prognosis of patients with breast cancer. Objectives To review the clinical effectiveness and cost-effectiveness evidence base for lapatinib (LAP) in combination with an aromatase inhibitor (AI) and trastuzumab (TRA) in combination with an AI for the first-line treatment of patients who have hormone receptor-positive (HR+)/human epidermal growth factor 2-positive (HER2+) mBC. Data sources Relevant electronic databases and websites, including MEDLINE, EMBASE and the Cochrane Library, were searched until May 2010. Further data were derived from the manufacturers’ submissions for LAP + AI and TRA + AI. Review methods A systematic review of the clinical effectiveness and cost-effectiveness of LAP + AI and TRA + AI was undertaken. As it was deemed inappropriate to compare LAP + AI with TRA + AI, two separate assessments of cost-effectiveness versus AIs alone were undertaken. Results Three trials were included in the systematic review [the patient populations of the efficacy and safety of lapatinib combined with letrozole (EGF30008) trial, the efficacy and safety of trastuzumab combined with anastrozole (TAnDEM) trial and the efficacy and safety of letrozole combined with trastuzumab (eLEcTRA) trial]. As a result of differences in the exclusion criteria and because one trial was halted prematurely, comparisons across trials were believed to be inappropriate and meta-analysis was not possible. Individually, however, the findings from the trials all suggest that LAP + AI or TRA + AI results in improved progression-free survival and/or time to progression when compared with AIs alone. The trials do not show a statistically significant benefit in terms of overall survival. Two separate economic analyses were conducted based on the completed trials; neither LAP + AI nor TRA + AI was found to be cost-effective when compared with AI monotherapy. Limitations Because of differences in the EGF30008 and the TAnDEM trials, the Assessment Group believes the indirect comparisons analyses conducted by the manufacturers are inappropriate and, for the same reason, chooses not to compare LAP + AI with TRA + AI in an economic evaluation. Conclusions LAP + AI and TRA + AI appear to be clinically more effective than AI monotherapy, but neither is cost-effective compared with AIs alone. It was not possible to compare LAP + AI with TRA + AI. Future research should include research into treating mBC in the HR+/HER2+ population who are not TRA (or LAP) naive and into comparing the clinical effectiveness of AIs as monotherapy in patients with HER2+ and human epidermal growth factor 2-negative breast cancer.

Background We aimed to review the efficacy and safety of recanalisation procedures for the treatment of PE. Methods We searched PubMed, the Cochrane Library, EMBASE, EBSCO, Web of Science and CINAHL databases from inception through 31 July 2015 and included randomised clinical trials that compared the effect of a recanalisation procedure versus each other or anticoagulant therapy in patients diagnosed with PE. We used network meta-analysis and multivariate random-effects meta-regression to estimate pooled differences between each intervention and meta-regression to assess the association between trial characteristics and the reported effects of recanalisation procedures versus anticoagulation. Results For all-cause mortality, there were no significant differences in event rates between any of the recanalisation procedures and anticoagulant treatment (full-dose thrombolysis: OR 0.60; 95% CI0.36 to 1.01; low-dose thrombolysis: 0.47; 95% CI 0.14 to 1.59; and catheter-associated thrombolysis: 0.31; 95% CI 0.01 to 7.96). Full-dose thrombolysis increased the risk of major bleeding (2.00; 95% CI 1.06 to 3.78) compared with anticoagulation. Catheter-directed thrombolysis was associated with the lowest probability of dying (surface under the cumulative ranking curve (SUCRA), 0.67), followed by low-dose thrombolysis (SUCRA, 0.66) and full-dose thrombolysis (SUCRA, 0.55). Similarly, low-dose thrombolysis was associated with the lowest probability of major bleeding (SUCRA, 0.61), followed by catheter-directed thrombolysis (SUCRA, 0.54) and full-dose thrombolysis (SUCRA, 0.17). The results were similar in sensitivity analyses based on restricting only to studies in haemodynamically stable patients with PE. Conclusions In the treatment of PE, recanalisation procedures do not seem to offer a clear advantage compared with standard anticoagulation. Low-dose thrombolysis was associated with the lowest probability of dying and bleeding. Trial registration number PROSPERO CRD42015024670.

Background: The National Institute for Health and Care Excellence (NICE) has issued multiple guidance for the first-line management of patients with lung cancer and recommends different combinations of chemotherapy treatments. This review provides a synthesis of clinical effectiveness and cost-effectiveness evidence supporting current guidance. Objectives: To evaluate the clinical effectiveness and cost-effectiveness of first-line chemotherapy currently licensed in Europe and recommended by NICE, for adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC). Data sources: Three electronic databases (MEDLINE, EMBASE and The Cochrane Library) were searched from 2001 to August 2010. Review methods: Trials that compared first-line chemotherapy currently licensed in Europe and recommended by NICE in chemotherapy-naive adult patients with locally advanced or metastatic NSCLC were included. Data on key outcomes including, but not limited to, overall survival (OS), progression-free survival (PFS) and adverse events (AEs) were extracted. For the assessment of cost-effectiveness, outcomes included incremental cost per quality-adjusted life-year (QALY) gained. Analyses were performed for three NSCLC subpopulations: patients with predominantly squamous disease, patients with predominantly non-squamous disease and patients with epidermal growth factor receptor (EGFR) mutation-positive (M+) status. Meta-analysis and mixed-treatment comparison methodology were conducted where appropriate. Results: Twenty-three trials involving > 11,000 patients in total met the inclusion criteria. The quality of the trials was poor. In the case of patients with squamous disease, there were no statistically significant differences in OS between treatment regimes. The mixed-treatment comparison demonstrated that, in patients with non-squamous disease, pemetrexed (Alimta (R), Eli Lilly and Company; PEM) + platinum (PLAT) increases OS statistically significantly compared with gemcitabine (Gemzar (R), Eli Lilly and Company; GEM) + PLAT [ hazard ratio (HR) = 0.85; 95% confidence interval (CI) 0.74 to 0.98] and that paclitaxel (Abraxane (R), Celgene Corporation; PAX) + PLAT increases OS statistically significantly compared with docetaxel (Taxotere (R), Sanofi-aventis; DOC) + PLAT (HR = 0.79, 95% CI 0.66 to 0.93). None of the comparisons found any statistically significant differences in OS among patients with EGFR M+ status. Direct meta-analysis showed a statistically significant improvement in PFS with gefitinib (Iressa (R), AstraZeneca; GEF) compared with DOC + PLAT and PAX + PLAT (HR = 0.49; 95% CI 0.33 to 0.73; and HR = 0.38; 95% CI 0.24 to 0.60, respectively). No papers related to UK decision-making were identified. A de novo economic model was developed. Using list prices (British National Formulary), cisplatin (CIS) doublets are preferable to carboplatin doublets, but this is reversed if electronic market information tool prices are used, in which case drug administration costs then become more important than drug acquisition costs. For patients with both squamous and non-squamous disease, moving from low to moderate willingness-to-pay thresholds, the preferred drugs are PAX -> GEM -> DOC. However, in patients with non-squamous disease, PEM + CIS resulted in increased OS and would be considered cost-effective up to 35,000 pound per QALY gained. For patients with EGFR M+, use of GEF compared with PAX or DOC yields very high incremental cost-effectiveness ratios. Vinorelbine (Navelbine (R), Pierre Fabre Pharmaceutical Inc.) was not shown to be cost-effective in any comparison. Limitations: Poor trial quality and a lack of evidence for all drug comparisons complicated and limited the data analysis. Outcomes and adverse effects are not consistently combined across the trials. Few trials reported quality-of-life data despite their relevance to patients and clinicians. Conclusions: The results of this comprehensive review are unique to NSCLC and will assist clinicians to make decisions regarding the treatment of patients with advanced NSCLC. The design of future lung cancer trials needs to reflect the influence of factors such as histology, genetics and the new prognostic biomarkers that are currently being identified. In addition, trials will need to be adequately powered so as to be able to test for statistically significant clinical effectiveness differences within patient populations. New initiatives are in place to record detailed information on the precise chemotherapy (and targeted chemotherapy) regimens being used, together with data on age, cell type, stage of disease and performance status, allowing for very detailed observational audits of management and outcomes at a population level. It would be useful if these initiatives could be expanded to include the collection of health economics data.

To evaluate the cost-effectiveness of the inclusion of trigger point–dry needling (TrP-DN) into an exercise program for the management of subacromial pain syndrome. Fifty patients with unilateral subacromial pain syndrome were randomized with concealed allocation to exercise alone or exercise plus TrP-DN. Both groups were asked to perform an exercise program targeting the rotator cuff musculature twice daily for five weeks. Patients allocated to the exercise plus TrP-DN group also received dry needling during the second and fourth sessions. Societal costs and health-related quality of life (estimated by EuroQol-5D-5L) over a one-year follow-up were used to generate incremental cost per quality-adjusted life-year (QALY) ratios for each intervention. Intention-to-treat analysis was possible for 48 (96%) of the participants. Those in the exercise group made more visits to medical doctors and received a greater number of other treatments (P < 0.001). The major contributor to societal costs (77%) was the absenteeism paid labor in favor of the exercise plus TrP-DN group (P = 0.03). The combination of exercise plus TrP-DN was less costly (mean difference cost/patient = €517.34, P = 0.003) than exercise alone. Incremental QALYs showed greater benefit for exercise plus TrP-DN (difference = 2.87, 95% confidence interval = 2.85–2.89). Therefore, the inclusion of TrP-DN into an exercise program was more likely to be cost-effective than an exercise program alone, with 99.5% of the iterations falling in the dominant area. The inclusion of TrP-DN into an exercise program was more cost-effective for individuals with subacromial pain syndrome than exercise alone. From a cost-benefit perspective, the inclusion of TrP-DN into multimodal management of patients with subacromial pain syndrome should be considered.

Background Occlusive vascular events such as myocardial infarction (MI), ischaemic stroke and transient ischaemic attack (TIA) are the result of a reduction in blood flow associated with an artery becoming narrow or blocked through atherosclerosis and atherothrombosis. Peripheral arterial disease is the result of narrowing of the arteries that supply blood to the muscles and other tissues, usually in the lower extremities. The primary objective in the treatment of all patients with a history of occlusive vascular events and peripheral arterial disease is to prevent the occurrence of new occlusive vascular events. Objectives To assess the clinical effectiveness and cost-effectiveness of clopidogrel and modified-release dipyridamole (MRD) alone or with aspirin (ASA) compared with ASA (and each other where appropriate) in the prevention of occlusive vascular events in patients with a history of MI, ischaemic stroke/TIA or established peripheral arterial disease. To consider the clinical effectiveness and cost-effectiveness of clopidogrel in patients with multivascular disease. This review is an update of the evidence base for the National Institute for Health and Clinical Excellence (NICE) guidance Technology Appraisal No. 90 (TA90) entitled Clopidogrel and modified-release dipyridamole for the prevention of occlusive vascular events (2005). Data sources Four electronic databases (EMBASE, MEDLINE, Web of Science and The Cochrane Library) were searched for randomised controlled trials (RCTs) and economic evaluations. Submissions to NICE by the manufacturers of the interventions were also considered. Review methods A systematic review of clinical effectiveness and cost-effectiveness was conducted. To manage heterogeneity between trials, indirect analysis (using a mixed-treatment methodology) was performed on selected clinical outcomes. A new economic model was developed to assess incremental costs per life-year gained [quality-adjusted life-years (QALYs)]. Results For evidence of clinical effectiveness, four RCTs were identified: CAPRIE (Clopidogrel versus Aspirin in Patients at Risk of Ischaemic Events), ESPRIT (European/Australasian Stroke Prevention in Reversible Ischaemia Trial), PRoFESS (Prevention Regimen For Effectively avoiding Second Strokes) and ESPS-2 (Second European Stroke Prevention Study). In CAPRIE (patients with MI, ischaemic stroke or peripheral arterial disease), statistically significant outcomes in favour of clopidogrel were noted for the primary outcome (first occurrence of ischaemic stroke, MI or vascular death) compared with ASA [relative risk reduction 8.7%; 95% confidence interval (CI) 0.3% to 16.5%; p = 0.043]. In ESPRIT (patients with ischaemic stroke/TIA) for the primary outcome (first occurrence of death from all vascular causes, non-fatal stroke, non-fatal MI or major bleeding complication), the risk of event occurrence was statistically significantly lower in the MRD + ASA arm than in the ASA arm [hazard ratio (HR) 0.80; 95% CI 0.66 to 0.98], with no statistically significant difference in bleeding events between the two arms. In PRoFESS (patients with ischaemic stroke) the rate of recurrent stroke of any type (primary outcome) was similar in the MRD + ASA and clopidogrel groups, and the null hypothesis (that MRD + ASA was inferior to clopidogrel) could not be rejected. In ESPS-2 (patients with ischaemic stroke/TIA), on the primary outcome of stroke, statistically significant differences in favour of MRD + ASA were observed compared with ASA and MRD alone (relative risk 0.76; 95% CI 0.63 to 0.93). The outcomes addressed in the mixed-treatment comparisons (limited by the available data) for the ischaemic stroke/TIA population confirmed the results of the direct comparisons. The 11 economic evaluations included in the review of cost-effectiveness indicated that for patients with previous peripheral arterial disease, ischaemic stroke or MI, clopidogrel is cost-effective compared with ASA, and for patients with previous ischaemic stroke/TIA, treatment with MRD + ASA is cost-effective compared with any other treatment in patients in the secondary prevention of occlusive vascular events. The relevance of the review was limited as the economic evaluations were not based on the most current clinical data. Cost-effectiveness results generated from the Assessment Group’s de novo economic model suggested that the most cost-effective approach for patients with ischaemic stroke/TIA is clopidogrel followed by MRD + ASA then ASA. For patients with MI, the most cost-effective approach is ASA followed by clopidogrel. For patients with established peripheral arterial disease, the most cost-effective approach is clopidogrel followed by ASA. For patients with multivascular disease, clopidogrel followed by ASA is the most cost-effective approach. Incremental cost-effectiveness ratios (ICERs) were also calculated for patients who are intolerant to ASA. Assuming that the branded price for clopidogrel is used and TA90 guidance is not applied, all of the ICERs range between £2189 and £13,558 per QALY gained. Probabilistic sensitivity analyses were fully consistent with these findings. Conclusions The evidence suggests that the most cost-effective treatment for patients with ischaemic stroke/TIA is clopidogrel followed by MRD + ASA followed by ASA; for patients with MI, ASA followed by clopidogrel; and for patients with established peripheral arterial disease or multivascular disease, clopidogrel followed by ASA.
