- Objective To investigate metabolic factors and their possible impact on risk of thyroid cancer. Methods A prospective cohort study was conducted based on seven population-based cohorts in Norway, Austria, and Sweden, in the Metabolic syndrome and Cancer project (Me-Can). Altogether 578,700 men and women with a mean age of 44.0 years at baseline were followed for on average 12.0 years. Relative risk of incident thyroid cancer was assessed by levels of BMI, blood pressure, and blood levels of glucose, cholesterol, triglycerides, and by a combined metabolic syndrome (MetS) score. Risk estimates were investigated for quintiles, and a z score distribution of exposures was analyzed using Cox proportional hazards regression. Results During follow-up, 255 women and 133 men were diagnosed with thyroid cancer. In women, there was an inverse association between glucose and thyroid cancer risk, with adjusted RR: 95% CI was 0.61 (0.41–0.90), p trend = 0.02 in the fifth versus the first quintile, and a positive association between BMI and thyroid cancer risk with a significant trend over quintiles. There was no association between the other metabolic factors, single or combined (Met-S), and thyroid cancer. Conclusion In women, BMI was positively, while blood glucose levels were inversely, associated with thyroid cancer.

- Purpose: Lifestyle-related conditions such as obesity are associated with prostate cancer progression, but the associations with hyperglycemia and dyslipidemia are unclear. This study, therefore, aims to examine the association of glucose, triglycerides, and total cholesterol with prostate cancer death. Methods: From the Swedish AMORIS cohort, we selected 14,150 men diagnosed with prostate cancer between 1996 and 2011 who had prediagnostic measurements of serum glucose, triglycerides, and total cholesterol. Multivariable Cox proportional hazards regressionmodels were used to determine the hazard ratios for death in relation to the aforementioned metabolic markers. Results: Using clinical cut-off points, a non-significant positive association was observed between glucose and prostate cancer death. When compared to those with glucose in the lowest quartile, those in the highest quartile had greater risk of prostate cancer death (HR 1.19; 95% CI 1.02-1.39). However, neither total cholesterol nor triglycerides were associated with prostate cancer death. Glucose and triglycerides were positively associated with overall, cardiovascular, and other deaths. Hypercholesterolemia was only associated with risk of CVD death. Conclusion: Our results suggest that glucose levels may influence prostate cancer survival, but further studies using repeated measurements are needed to further elucidate how glucose levels may influence prostate cancer progression.

Journal article (peer-reviewed)abstract
- To assess the association between serum triglyceride levels and cancer risk. The metabolic syndrome and cancer project (Me-Can) includes cohorts from Norway, Austria, and Sweden; the current study included data on 257,585 men and 256,512 women. The mean age at study entry was 43.8 years for men and 44.2 years for women. The mean follow-up time was 13.4 years (SD = 8.5) for men and 11.9 years (SD = 7.2) for women. Excluding the first year of follow-up, 23,060 men and 15,686 women were diagnosed with cancer. Cox regression models were used to calculate relative risk (RR) of cancer for triglyceride levels in quintiles and as a continuous variable. RRs were corrected for random error by use of regression dilution ratio. Relative risk for top quintile versus bottom quintile of triglycerides of overall cancer was 1.16 (95% confidence interval 1.06-1.26) in men and 1.15 (1.05-1.27) in women. For specific cancers, significant increases for top quintile versus bottom quintile of triglycerides among men were found for cancers of the colon, respiratory tract, the kidney, melanoma and thyroid and among women, for respiratory, cervical, and non-melanoma skin cancers. Data from our study provided evidence for a possible role of serum triglycerides in cancer development.

Prospective cohort study of metabolic risk factors and gastric adenocarcinoma risk in the Metabolic Syndrome and Cancer Project (Me-Can)

Journal article (peer-reviewed)abstract
- Little is known about the association between the metabolic syndrome (MetS) and the risk of gastric adenocarcinoma. The aim of this study was to investigate whether metabolic risk factors, together or combined, were associated with the risk of gastric adenocarcinoma. The Metabolic Syndrome and Cancer Project (Me-Can) is a pooling of prospective cohorts in Austria, Norway, and Sweden with information on blood pressure, lipids, glucose, and BMI available in 578,700 individuals. Cox proportional hazards analysis was used to calculate hazard ratio (HR) of gastric adenocarcinoma using metabolic risk factors categorized into quintiles and transformed into z-scores (with mean = 0 and SD = 1). The standardized sum of all z-scores created a composite MetS score. In total, 1,210 incident cases of gastric adenocarcinoma were identified. Glucose was significantly associated with the risk of gastric adenocarcinoma [calibrated HR 1.58 (1.14-2.20) per one unit increment in z-score] in women. There was a statistically significant association between triglycerides and risk of gastric adenocarcinoma per mmol increment in triglycerides [HR 1.20 (1.06-1.36) per mmol] but not for the adjusted z-score in women. There were no significant association between any metabolic factors and gastric cancer among men. The composite MetS score was associated with the risk of gastric adenocarcinoma in women [HR 1.18 (1.00-1.38) per one unit increment in z-score] but not in men. Glucose and high levels of the composite MetS score were associated with an increased risk of gastric adenocarcinoma in women but not in men.

Journal article (peer-reviewed)abstract
- PURPOSE: To assess the association between height and risk of cancer and cancer death.METHODS: The metabolic syndrome and cancer project is a prospective pooled cohort study of 585,928 participants from seven cohorts in Austria, Norway, and Sweden. Hazard ratios (HRs) and 95 % confidence intervals (CIs) for cancer incidence and death were estimated in height categories and per 5-cm increment for each cancer site using Cox proportional hazards model.RESULTS: During a mean follow-up of 12.7 years (SD = 7.2), 38,862 participants were diagnosed with cancer and 13,547 participants died of cancer. Increased height (per 5-cm increment) was associated with an increased overall cancer risk in women, HR 1.07 (95 % CI 1.06-1.09), and in men, HR 1.04 (95 % CI 1.03-1.06). The highest HR was seen for malignant melanoma in women, HR 1.17 (95 % CI 1.11-1.24), and in men HR 1.12 (95 % CI 1.08-1.19). Height was also associated with increased risk of cancer death in women, HR 1.03 (95 % CI 1.01-1.16), and in men, HR 1.03 (95 % CI 1.01-1.05). The highest HR was observed for breast cancer death in postmenopausal women (>60 years), HR 1.10 (95 % CI 1.00-1.21), and death from renal cell carcinoma in men, HR 1.18 (95 % CI 1.07-1.30). All these associations were independent of body mass index.CONCLUSION: Height was associated with risk of cancer and cancer death indicating that factors related to height such as hormonal and genetic factors stimulate both cancer development and progression.
