  • Metabolic risk factors and ovarian cancer in the metabolic syndrome and cancer project
  • 2011
  • Ingår i: International Journal of Epidemiology. - : Oxford University Press (OUP). - 0300-5771 .- 1464-3685. ; 40:6, s. 1667-1677

    • BACKGROUND: No studies have so far evaluated the impact of the metabolic syndrome (MetS) as an entity on ovarian cancer risk. The authors aimed to examine the association between factors in the MetS, individually and combined, and risk of ovarian cancer incidence and mortality. METHODS: Altogether, 290 000 women from Austria, Norway and Sweden were enrolled during 1974-2005, with measurements taken of height, weight, blood pressure and levels of glucose, cholesterol and triglycerides. Relative risks (RRs) of ovarian cancer were estimated using Cox regression for each MetS factor in quintiles and for standardized levels (z-scores), and for a composite z-score for the MetS. RRs were corrected for random error in measurements. RESULTS: During follow-up, 644 epithelial ovarian cancers and 388 deaths from ovarian cancer were identified. There was no overall association between MetS and ovarian cancer risk. Increasing levels of cholesterol [RR 1.52, 95% confidence interval (95% CI) 1.01-2.29, per 1-U increment of z-score] and blood pressure (RR 1.79, 95% CI 1.12-2.86) conferred, however, increased risks of mucinous and endometrioid tumours, respectively. In women below the age of 50 years, there was increased risk of ovarian cancer mortality for MetS (RR 1.52, 95% CI 1.00-2.30). Increasing levels of BMI (RR 1.17, 95% CI 1.01-1.37) conferred increased risk of ovarian cancer mortality in women above the age of 50 years. CONCLUSION: There was no overall association between MetS and ovarian cancer risk. However, increasing levels of cholesterol and blood pressure increased the risks of mucinous and endometrioid tumours, respectively. Increasing levels of BMI conferred an increased risk of ovarian cancer mortality in women above the age of 50 years.

  • Metabolic syndrome and breast cancer in the me-can (metabolic syndrome and cancer) project.
  • 2010
  • Ingår i: Cancer Epidemiology, Biomarkers and Prevention. - 1055-9965 .- 1538-7755. ; 19:7, s. 1737-1745

    • BACKGROUND: Few studies have assessed the metabolic syndrome (MetS) as an entity in relation to breast cancer risk, and results have been inconsistent. We aimed to examine the association between MetS factors (individually and combined) and risk of breast cancer incidence and mortality. METHODS: Two hundred ninety thousand women from Austria, Norway, and Sweden were enrolled during 1974-2005, with measurements of height, weight, blood pressure, and levels of glucose, cholesterol, and triglycerides. Relative risks (RR) of breast cancer were estimated using Cox proportional hazards regression for each MetS factor in quintiles and for standardized levels (z-scores) and for a composite z-score for the MetS. RESULTS: There were 4,862 incident cases of breast cancer and 633 deaths from breast cancer identified. In women below age 50, there was a decreased risk of incident cancer for the MetS (per 1-unit increment of z-score; RR, 0.83; 95% confidence interval, 0.76-0.90) as well as for the individual factors (except for glucose). The lowest risks were seen among the heaviest women. In women above age 60, there was an increased risk of breast cancer mortality for the MetS (RR, 1.23; 95% confidence interval, 1.04-1.45) and for blood pressure and glucose. The strongest association with mortality was seen for increased glucose concentrations. CONCLUSIONS: The MetS was associated with a decreased risk of incident breast cancer in women below age 50 with high body mass index, and with an increased risk of breast cancer mortality in women above 60. IMPACT: Lifestyle interventions as recommended for cardiovascular disease prevention may be of value to prevent breast cancer mortality in postmenopausal women.

  • Metabolic syndrome and endometrial carcinoma
  • 2010
  • Ingår i: American Journal of Epidemiology. - : Oxford University Press (OUP). - 0002-9262 .- 1476-6256. ; 171:8, s. 892-902

    • The authors examined the association between the metabolic syndrome and risk of incident endometrial and fatal uterine corpus cancer within a large prospective cohort study. Approximately 290,000 women from Austria, Norway, and Sweden were enrolled during 1974-2005, with measurements of height, weight, systolic and diastolic blood pressure, and circulating levels of glucose, total cholesterol, and triglycerides. Relative risks were estimated using Cox proportional hazards regression. The metabolic syndrome was assessed as a composite z score, as the standardized sum of z scores for body mass index, blood pressure, glucose, cholesterol, and triglycerides. A total of 917 endometrial carcinomas and 129 fatal cancers were identified. Increased risks of incident endometrial carcinoma and fatal uterine corpus cancer were seen for the metabolic syndrome factors combined, as well as for individual factors (except for cholesterol). The relative risk of endometrial carcinoma for the metabolic syndrome was 1.37 (95% confidence interval: 1.28, 1.46) per 1-unit increment of z score. The positive associations between metabolic syndrome factors (both individually and combined) and endometrial carcinoma were confined to the heaviest women. The association between the metabolic syndrome and endometrial carcinoma risk seems to go beyond the risk conferred by obesity alone, particularly in women with a high body mass index.

  • Metabolic factors and risk of colorectal cancer in the metabolic syndrome and cancer project (Me-Can)
  • 2011
  • Ingår i: Cancer. - : Wiley. - 0008-543X .- 1097-0142. ; 117:11, s. 2398-2407
  • Tidskriftsartikel (refereegranskat)abstract
    • Background The metabolic syndrome (MetS) has been related to an increased risk of colorectal cancer in some small studies, but it is unknown which factors in the MetS that are most strongly related to risk, and if there is an interaction between factors. Methods and Findings In the Metabolic syndrome and Cancer project (Me-Can), data on body mass index (BMI), blood pressure, and blood levels of glucose, cholesterol, and triglycerides were available in 289,866 men and 288,834 women. Mean age at baseline was 44.0 years and mean follow-up time was 12.0 years. During follow-up, 2,834 men and 1,861 women were diagnosed with colorectal cancer. We used Cox regression models to calculate relative risk (RR) of colorectal cancer by exposures transformed into Z scores (mean = 0, standard deviation = 1), and for a MetS Z score, and used regression calibration to correct exposure levels for random error in measurement. Significant increases in risk per one unit increment of factors were observed in men for BMI, RR 1.07 (95% confidence interval, 1.02-1.13), blood pressure, RR 1.10 (1.02-1.18), and triglycerides, RR 1.17 (1.06-1.28), and in women for BMI, RR 1.08 (1.01-1.15). The RR of colorectal cancer per one unit increment of the MetS Z score was 1.24 (1.18-1.31) in men, and 1.14 (1.06-1.22) in women. There was no significant positive interaction for any combination of two metabolic factors. Associations between metabolic factors and risk of fatal colorectal cancer were similar to those for incident cancer. Conclusions Our data add further evidence for an association between factors in the MetS, in single and combined, and risk of colorectal cancer. Our data do not support an interaction between factors in the MetS on risk.
