Abstract
Background: Predictors of premature death and cancer development are needed to more precisely identify individuals who may warrant preventive intervention. Circulating IGF binding protein-7 (IGFBP7) and, to lesser extent, the IGFBP7/IGF-1 ratio are emerging biomarkers of renal and cardiovascular morbidity. However, their relationships with aging, obesity, mortality and cancer risk remain unclear.
Methods: This hypothesis-generating study investigated plasma IGFBP7, IGF-1, and their ratio as predictors of all-cause mortality, any cancer (excluding nonmelanoma skin cancer), obesity-related cancer (composite of 13 cancer types), and breast cancer incidence in a large longitudinal cohort of postmenopausal women. We assessed relationships of each biomarker with age, body mass index (BMI), and each outcome (bivariately and controlling for age, BMI, race, physical activity, education, income, marital status, alcohol intake, smoking, diabetes, and hormone therapy) in 793 Women's Health Initiative-Observational Study participants (mean 19.4 year follow-up).
Results: In adjusted analyses, IGFBP7 increased with age and obesity, and was positively associated with risks of all-cause mortality [hazard ratio (HR)=2.42 (95% CI: 1.37-4.26), p=0.002], any cancer [HR=2.04 (1.05-3.94), p=0.035], and obesity-related cancer [HR=1.58 (0.99-2.51), p=0.053]. Also in adjusted analyses, the IGFBP7/IGF-1 ratio increased with age and was positively associated with all-cause mortality [HR=1.51 (1.14-1.99), p=0.004] and any cancer incidence [HR=5.44 (1.13-26.1), p=0.034].
Conclusions: Plasma IGFBP7 and the IGFBP7/IGF1 ratio are positively associated with age, obesity (IGFBP7 only), mortality, and cancer in postmenopausal women.
Impact: Plasma IGFBP7 may represent an age- and obesity-sensitive biomarker of increased risk of developing cancer and/or dying prematurely.
期刊介绍:
Cancer Epidemiology, Biomarkers & Prevention publishes original peer-reviewed, population-based research on cancer etiology, prevention, surveillance, and survivorship. The following topics are of special interest: descriptive, analytical, and molecular epidemiology; biomarkers including assay development, validation, and application; chemoprevention and other types of prevention research in the context of descriptive and observational studies; the role of behavioral factors in cancer etiology and prevention; survivorship studies; risk factors; implementation science and cancer care delivery; and the science of cancer health disparities. Besides welcoming manuscripts that address individual subjects in any of the relevant disciplines, CEBP editors encourage the submission of manuscripts with a transdisciplinary approach.
