Two binding proteins, SHBG and IGF-binding protein-1 (IGFBP-1), are both down-regulated by insulin and therefore could serve as potential indicators of the metabolic syndrome and hyperinsulinemia-related cardiovascular risk. We compared serum SHBG and IGFBP-1 as potential markers of abnormal glucose tolerance, the metabolic syndrome, diabetes mellitus, cardiovascular risk factors, and total, cardiovascular, and coronary heart disease mortality in elderly men. Of the original cohort of 1711 men, 524 were alive on January 1, 1989, and 413 participated in the 30-yr examination, of whom 335 men, aged 70-89 yr, formed the study group for the present analysis. Low SHBG and IGFBP-1 were both associated with an increased prevalence of abnormal glucose tolerance and the metabolic syndrome, but only SHBG was associated with diabetes mellitus. SHBG was less influenced by body mass index than IGFBP-1. Low SHBG indicated increased cardiovascular and coronary disease mortality; the association remained after adjustment for abnormal glucose tolerance, but not after adjustment for prevalent cardiovascular disease. IGFBP-1 had no association with mortality. It is concluded that low SHBG is a better indicator of increased cardiovascular mortality than low or high IGFBP-1.

Insulin-like growth factor binding protein-1 (IGFBP-1) has been implicated in the development of cardiovascular disease, but it is not known whether IGFBP-1 is related to cardiovascular mortality. We examined the relation of circulating IGFBP-1 to death from coronary heart disease, cardiovascular disease, and all causes in a cohort study consisting of 622 men aged 65 - 84 years, at baseline in 1984. Fasting serum IGFBP-1 and other risk factors were measured in 1984 and 1989. Cardiovascular events for those who died between 1984 and 1995 were analyzed, and cardiovascular diagnoses were coded centrally according to standardized procedures. Of the 622 men, 358 died between 1984 and 1995; 160 deaths were due to cardiovascular causes, 113 of which were coronary deaths. High fasting serum IGFBP-1 concentration (> 75 percentile) in 1984 was associated with increased five-year total mortality (OR 2.05, 95 % CI 1.41 - 2.99; p < 0.0002), cardiovascular mortality (OR 2.20, 95 % CI 1.37 - 3.50; p < 0.0009) and coronary heart disease mortality (OR 2.29, 95 % CI 1.35 - 3.88; p < 0.002). After adjustment for age, high serum IGFBP-1 concentrations still carried an increased risk of total mortality due to (OR 1.73, 95 % CI 1.16 - 2.59; p < 0.007), cardiovascular (OR 1.91 95 % CI 1.18 - 3.09; p < 0.008) and coronary heart disease (OR 2.02. 95 % CI 1.18 - 3.47; p < 0.01). In conclusion, high fasting serum IGFBP-1 is related to increased five-year total and cardiovascular mortality in elderly men.

AGO‐OVAR 12 investigated the effect of adding the oral triple angiokinase inhibitor nintedanib to standard front‐line chemotherapy for advanced ovarian cancer. At the primary analysis, nintedanib demonstrated significantly improved progression‐free survival (PFS; primary endpoint) compared with placebo. We report final results, including overall survival (OS). Patients with primary debulked International Federation of Gynaecology and Obstetrics (FIGO) stage IIB–IV newly diagnosed ovarian cancer were randomised 2:1 to receive carboplatin (area under the curve 5 or 6) plus paclitaxel (175 mg/m2) on day 1 every 3 weeks for six cycles combined with either nintedanib 200 mg or placebo twice daily on days 2–21 every 3 weeks for up to 120 weeks. Between December 2009 and July 2011, 1,366 patients were randomised (911 to nintedanib, 455 to placebo). Disease was considered as high risk (FIGO stage III with >1 cm residuum, or any stage IV) in 39%. At the final analysis, 605 patients (44%) had died. There was no difference in OS (hazard ratio 0.99, 95% confidence interval [CI] 0.83–1.17, p = 0.86; median 62.0 months with nintedanib vs. 62.8 months with placebo). Subgroup analyses according to stratification factors, clinical characteristics and risk status showed no OS difference between treatments. The previously reported PFS improvement seen with nintedanib did not translate into an OS benefit in the nonhigh‐risk subgroup. Updated PFS results were consistent with the primary analysis (hazard ratio 0.86, 95% CI 0.75–0.98; p = 0.029) favouring nintedanib. The safety profile was consistent with previous reports.

Serum insulin-like growth factor-binding protein-1 (IGFBP-1) is regulated by insulin and has been suggested to be a marker of the insulin resistance syndrome. The aim of this study was to investigate whether serum IGFBP-1 is associated with cardiovascular risk factors. Serum insulin-like growth factor-I and IGFBP-3 were also determined. 331 men aged 70-89 years were examined from the Finnish cohort of the Seven Countries Study. Serum IGFBP-1 concentrations were measured by immunofluorometric assay, and the results were analysed with respect to markers of cardiovascular risk, insulin resistance, and insulin secretion that were determined by using the homeostasis model assessment. Fasting serum IGFBP-1 correlated inversely with fasting serum insulin, serum insulin 2 h after oral glucose challenge test, body mass index, and serum triglycerides, and it correlated positively with age and serum high-density lipoprotein (HDL) cholesterol. After adjustment for age, fasting serum IGFBP-1 correlated positively with HDL cholesterol and inversely with fasting serum insulin and triglycerides. Serum IGFBP-1 correlated positively with insulin sensitivity and negatively with beta-cell function. In conclusion, low serum IGFBP-1 levels in elderly men are associated with a number of cardiovascular risk factors.
