Sentinel-lymph-node-based management or routine axillary clearance? Three-year outcomes of the RACS Sentinel Node Biopsy versus Axillary Clearance (SNAC) 1 trial

Purpose We sought to determine whether the benefits of sentinel-node-based management (SNBM) over routine axillary clearance (RAC) at 1 year persisted to 3 years of follow-up. Methods 1088 women with clinically node negative breast cancer were randomly assigned to SNBM versus RAC. Upper limb volume, symptoms and function were assessed at 1, 6, 12, 24 and 36 months after surgery objectively with upper limb measurements by clinicians, and subjectively by patients’ using validated self-rating scales. Results Upper limb volume increased in both groups over the first 2 years and differed between the two groups all time points beyond 1 month (P<0.02), but then plateaued. Upper limb swelling was no worse in women who had axillary clearance as two-stage procedure than in women assigned RAC as a one-stage procedure. Upper limb volume had increased 15% or more in 6.0% at 6 months and 17.6% at 3 years in those assigned RAC versus 4.2% and 11.9% in those assigned SNBM. Reductions in upper limb movement were also greater with RAC than SNBM over 6 months, but improved and were similar in the two groups from 1 to 3 years. Subjective ratings of upper limb swelling, symptoms, dysfunction, and disability over 3 years were worse in the RAC group. Upper limb swelling at 3 years was rated severe by few women (1.1%), but moderate by 9.4% in the RAC group and 2.5% in the SNBM group (P<0.001). Conclusions The benefits of SNBM over RAC persist 3 years after surgery.Royal Australasian College of Surgeon

The cost effectiveness of bevacizumab when added to capecitabine, with or without mitomycin-C, in first line treatment of metastatic colorectal cancer: results from the Australasian phase III MAX study

Background: Based on the clinical data, bevacizumab has been approved in Australia and globally for the treatment of advanced colorectal cancer. However, limited evidence exists for its cost-effectiveness. The purpose of this study was to evaluate the cost effectiveness of adding bevacizumab to capecitabine monotherapy in patients with metastatic colorectal cancer, using data from the prospective economic evaluation conducted alongside the MAX trial. Methods: Individual patient level data on resource use and progression free survival were prospectively collected in the phase III MAX trial. Resource use data were collected for the period between randomisation and disease progression, and unit costs were assigned from the perspective of the Australian health care funder. Effectiveness was measured in quality adjusted progression free survival years, with utility scores obtained from both the community valued EQ-5D questionnaire and the patient valued UBQ-C questionnaire. Progression free survival was used as a secondary effectiveness measure. Results: The addition of bevacizumab to capecitabine monotherapy cost approximately $192,156 (95$135,619 to $326,894) per quality adjusted progression free survival year gained when using publicly listed pharmaceutical prices and utility values from the EQ-5D questionnaire. This decreased to$149,455 (95% CI, $100,356 to$245,910) when values from the UBQ-C questionnaire were applied. The incremental cost per progression free survival year was $145,059 (95$106,703 to $233,225). Conclusions: Bevacizumab was not found to be cost effective at its listed price, based on results from the MAX trial.Roche Products Pty Lt

Hepatic and renal end-organ damage in the Fontan circulation: a report from the Australian and New Zealand Fontan Registry

Background: Hepatic and renal dysfunction have been observed in survivors of the Fontan procedure, however their incidence and associated factors remain poorly defined. Methods: A total of 152 participants from a Registry of 1528 patients underwent abdominal ultrasound, transient elastography (FibroScan), serum fibrosis score (FibroTest), in vivo Tc-99m DTPA measurement of glomerular filtration rate (mGFR), and urine albumin-creatinine ratio (ACR). Results: Mean age and time since Fontan were 19.8 ± 9.3 and 14.1 ± 7.6 years, respectively. Features suggestive of hepatic fibrosis were observed on ultrasound in 87/143 (61%) and no patient was diagnosed with hepatocellular carcinoma. FibroScan median kPa was ≥10 in 117/133 (88%), ≥15 in 75/133 (56%), and ≥20 in 41/133 (31%). Fifty-four patients (54/118, 46%) had a FibroTest score ≥0.49 (equivalent to ≥F2 fibrosis). FibroTest score correlated with FibroScan value (r = 0.24, p = 0.015) and ACR (r = 0.29, p = 0.002), and patients with ultrasound features of hepatic fibrosis had a higher FibroScan median kPa (19.5 vs 15.4, p = 0.002). Renal impairment was mild (mGFR 60–89 ml/min/1.73 m) in 46/131 (35%) and moderate (mGFR 30–59 ml/min/1.73 m) in 3/131 (2%). Microalbuminuria was detected in 52/139 participants (37%). By multivariable analysis, time since Fontan was associated with increased FibroScan median kPa (β = 0.89, 95% CI 0.54–1.25, p = 0.002) and decreased mGFR (β = −0.77, 95% CI −1.29–0.24, p = 0.005). Conclusions: In the second decade after Fontan hepatic and renal structure and function are abnormal in a significant number of patients: close to 60% have ultrasonographic evidence of structural hepatic abnormalities, 46% have elevated serum hepatic fibrosis scores, and 57% have either reduced glomerular filtration rate or microalbuminuria. Hepatic and renal function should be monitored for potential impacts on outcomes after Fontan completion

Multidisciplinary Prognostication Using the Palliative Prognostic Score in an Australian Cancer Center

Context Accurate prognostication is important in oncology and palliative care. A multidisciplinary approach to prognostication provides a novel approach, but its accuracy and application is poorly researched. In this study, we describe and analyze our experience of multidisciplinary prognostication in palliative care patients with cancer. Objectives To assess our accuracy of prognostication using multidisciplinary team prediction of survival (MTPS) alone and within the Palliative Prognostic (PaP) Score. Methods This retrospective study included all new patients referred to a palliative care consultation service in a tertiary cancer center between January 2010 and December 2011. Initial assessment data for 421 inpatients and 223 outpatients were analyzed according to inpatient and outpatient groups to evaluate the accuracy of prognostication using MTPS alone and within the PaP score (MTPS-PaP) and their correlation with overall survival. Results Inpatients with MTPS-PaP group A, B, and C had a median survival of 10.9, 3.4, and 0.7 weeks, respectively, and a 30-day survival probability of 81%, 40%, and 10%, respectively. Outpatients with MTPS-PaP group A and B had a median survival of 17.3 and 5.1 weeks, respectively, and a 30-day survival probability of 94% and 50%, respectively. MTPS overestimated survival by a factor of 1.5 for inpatients and 1.2 for outpatients. The MTPS-PaP score correlated better than MTPS alone with overall survival. Conclusion This study suggests that a multidisciplinary team approach to prognostication within routine clinical practice is possible and may substitute for single clinician prediction of survival within the PaP score without detracting from its accuracy. Multidisciplinary team prognostication can assist treating teams to recognize and articulate prognosis, facilitate treatment decisions, and plan end-of-life care appropriately. PaP was less useful in the outpatient setting, given the longer survival interval of the outpatient palliative care patient group

Long‐term outcomes of pacemaker implantation in children with univentricular versus complex biventricular surgical repair

Abstract Objective Pacing in a univentricular circulation has been associated with worsened outcomes. We investigated the long‐term outcomes of pacing in children with a univentricular circulation compared to a complex biventricular circulation. We also identified predictors of adverse outcomes. Methods A retrospective study of all children with major congenital heart disease who underwent pacemaker implantation under the age of 18 years between November 1994 and October 2017. Results Eighty‐nine patients were included; 19 with a univentricular and 70 with a complex biventricular circulation. A total of 96% of pacemaker systems were epicardial. Median follow up was 8.3 years. The incidence of adverse outcome was similar between the two groups. Five (5.6%) patients died and two (2.2%) underwent heart transplantation. Most adverse events occurred within the first 8 years after pacemaker implantation. Univariate analysis identified five predictors of adverse outcomes in the patients in the biventricular but none in the univentricular group. The predictors of adverse outcome in the biventricular circulation were a right morphologic ventricle as the systemic ventricle, age at first congenital heart disease (CHD) operation, number of CHD operations, and female gender. The nonapical lead position was associated with a much higher risk of an adverse outcome. Conclusions Children with a pacemaker and a complex biventricular circulation have similar survival to the ones with a pacemaker and a univentricular circulation. The only modifiable predictor was the epicardial lead position on the paced ventricle, emphasizing the importance of apical placement of the ventricular lead

Favourable effects of fenofibrate on lipids and cardiovascular disease in women with type 2 diabetes: results from the Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) study

Aims/hypothesis In the double-blind placebo-controlled Fenofibrate Intervention and Event Lowering in Diabetes trial (n=9795), fenofibrate reduced major cardiovascular events in type 2 diabetes. Sex-related differences in fenofibrate response could be clinically relevant and were pre-specified analyses. Methods Women (n=3657) and men (n= 6138) with type 2 diabetes not using statins were assigned fenofibrate (200 mg/day) or placebo for 5 years. Effects on lipoproteins and total cardiovascular events were evaluated by sex. Results Baseline total, LDL-, HDL- and non-HDL cholesterol and apolipoproteins A-I and B differed between sexes, and these and triacylglycerol levels improved with fenofibrate in both sexes (all p0.1). In patients with high triacylglycerol levels and low HDL-cholesterol, fenofibrate reduced total cardiovascular outcomes by 24% (95% CI 2%, 42%) in women and 30% (7%, 54%) in men, with no treatment-by-sex interaction (p>0.1). Conclusions/interpretation Fenofibrate improved the lipoprotein profile more in women than men. Cardiovascular event reductions with fenofibrate among women were consistently similar to men, including among those with low HDL-cholesterol and high triacylglycerol levels. These data provide reassurance about fenofibrate efficacy in women and men. Both sexes with type 2 diabetes should be considered for fenofibrate therapy for cardioprotection

Atrioventricular valve failure in fontan palliation

BACKGROUND Atrioventricular valve failure (moderate or greater regurgitation, or valve operation) is a risk factor for adverse outcomes in patients undergoing Fontan palliation.OBJECTIVES This study determined the incidence of atrioventricular valve failure and its clinical impact on patients undergoing Fontan palliation.METHODS A retrospective cohort longitudinal study was conducted using patient data extracted from an existing bi-national, population-based registry.RESULTS A total of 1,468 patients who underwent Fontan palliation were identified; complete follow-up data were available for 1,199 patients. Six hundred eighty-six patients had 2 atrioventricular valves, 286 had a single mitral valve, 130 had a common atrioventricular valve, and 97 had a single tricuspid valve. A total of 132 repairs were performed in 110 patients, and 15 replacements were performed in 13 patients, The cumulative incidence of atrioventricular valve failure at 25 years of age for patients with a common atrioventricutar, single tricuspid, single mitral, and 2 atrioventricutar valves was 56% (95% confidence interval [CI]: 46% to 67%), 46% (95% CI: 31% to 61%), 8% (95% CI: 4% to 12%), and 26% (95% CI: 21% to 30%), respectively. In patients without valve failure, freedom from Fontan failure at 10 and 20 years post-Fontan palliation was 91% (95% CI: 89% to 93%) and 77% (95% CI: 73% to 81%), respectively, compared with 77% (95% CI: 69% to 85%) and 54% (95% CI: 42% to 68%), respectively, in patients with valve failure (hazard ratio: 2.43; 95% CI: 1.74 to 3.39; p < 0.001).CONCLUSIONS Atrioventricular valve failure occurs frequently in patients undergoing Fontan palliation. Patients with valve failure are twice as likely to have their Fontan circulation fail than those without valve failure. (C) 2019 by the American College of Cardiology Foundation
