Association of type and location of BRCA1 and BRCA2 mutations with risk of breast and ovarian cancer.

Abstract: Limited information about the relationship between specific mutations in BRCA1 or BRCA2 (BRCA1/2) and cancer risk exists.

Evaluation of the efficacy and safety of RLY5016, a polymeric potassium binder, in a double-blind, placebo-controlled study in patients with chronic heart failure (the PEARL-HF) trial

Abstract: Aims To evaluate efficacy and safety of RLY5016 (a non-absorbed, orally administered, potassium [K+]-binding polymer) on serum K+ levels in patients with chronic heart failure (HF) receiving standard therapy and spironolactone. Methods and results One hundred and five patients with HF and a history of hyperkalaemia resulting in discontinuation of a renin–angiotensin–aldosterone system inhibitor/blocker and/or beta-adrenergic blocking agent or chronic kidney disease (CKD) with an estimated glomerular filtration rate of 5.5 mEq/L); and the proportion titrated to spironolactone 50 mg/day. Safety assessments included adverse events (AEs) and clinical laboratory tests. RLY5016 ( n = 55) and placebo ( n = 49) patients had similar baseline characteristics. At the end of treatment, compared with placebo, RLY5016 had significantly lowered serum K+ levels with a difference between groups of −0.45 mEq/L ( P < 0.001); a lower incidence of hyperkalaemia (7.3% RLY5016 vs. 24.5% placebo, P = 0.015); and a higher proportion of patients on spironolactone 50 mg/day (91% RLY5016 vs. 74% placebo, P = 0.019). In patients with CKD ( n = 66), the difference in K+ between groups was −0.52 mEq/L ( P = 0.031), and the incidence of hyperkalaemia was 6.7% RLY5016 vs. 38.5% placebo ( P = 0.041). Adverse events were mainly gastrointestinal, and mild or moderate in severity. Adverse events resulting in study withdrawal were similar (7% RLY5016, 6% placebo). There were no drug-related serious AEs. Hypokalaemia (K+ <3.5 mEq/L) occurred in 6% of RLY5016 patients vs. 0% of placebo patients ( P = 0.094). Conclusion RLY5016 prevented hyperkalaemia and was relatively well tolerated in patients with HF receiving standard therapy and spironolactone (25–50 mg/day) (ClinicalTrials.gov registry identifier: [NCT00868439][1]).

Prognostic factors of long-term outcome in gastroenteropancreatic neuroendocrine tumours.

Abstract: Neuroendocrine tumours (NET) of the gastroenteropancreatic system comprise a malignant entity with a low incidence. Only limited information is available on long-term clinical outcome and clinically applicable prognostic factors. We performed a retrospective analysis of a large, well-characterized centre-based patient cohort of 399 patients with histologically proven NET. Data were analysed according to epidemiological, clinical and histopathological characteristics. Detailed survival analyses using the Kaplan-Meier method were performed. Prognostic factors were tested by log-rank testing and independent risk factors were analysed using a Cox regression model. In the studied cohort, primary tumours originated in the fore-, mid- and hindgut in 46.1, 37.1 and 4.5% respectively. Extra-intestinal or unknown primary tumours were present in 8.4 and 10.5% respectively. Distant metastasis was present at initial diagnosis in 69.4%. Most frequent metastatic sites were liver (85%), peritoneal cavity (18%), bones (8%), other intra-abdominal sites (6%) and lungs (4%). Overall, 5- and 10-year survival rates were 78 and 63% respectively. Time to progression after initial diagnosis was significantly shorter in pancreatic as compared with ileal NET. Survival analysis revealed significantly better clinical outcome for primary tumours smaller than 25 mm, absence of metastasis, absence of any clinical symptoms, positive immunohistochemical staining for chromogranin A and a lower Ki67 index. These results were confirmed as independent by multivariate analysis. Therefore, this large retrospective analysis of a well-documented cohort of patients with NET demonstrates several prognostic factors of clinical relevance and wide availability, which should be considered for risk stratification in the management of NET.
