METS-IR was calculated based on fasting glucose, triglycerides and other indicators, with follow-up until December 31, 2019. Weighted Cox models and other analyses were performed. The results showed that each 1-unit increase in METS-IR was associated with a 3% higher risk of cancer-specific mortality (P = .01), presenting an approximately linear dose–response relationship; METS-IR remained associated with cancer mortality risk when analyzed asa categorical variable. Subgroup analyses revealed a significant interaction between hypertension and METS-IR in relation to cancer mortality, and stratified analyses further indicated that hypertension status acted as an effect modifier of this association. Sensitivity analyses confirmed the robustness of these findings. Higher METS-IR was independently associated with increased risks of cancer mortality in the US population, with hypertension significantly amplifying this association. |\n| --- |\n| Abbreviations: BMI = body mass index, CI = confidence intervals, HDL-C = high-density lipoprotein cholesterol, HR = hazard ratios, MEC = mobile examination center, METS-IR = metabolic score for insulin resistance, NDI = National Death Index, NHANES = the National Health and Nutrition Examination Survey, PIR = poverty-income ratio, T2DM = type 2 diabetes mellitus. |\n| Keywords: cancer mortality, general population, hypertension, metabolic score for insulin resistance, NHANES |\n\n1. Introduction  \nCancer remains one of the leading causes of morbidity and mortality worldwide. Despite substantial advances in cancer prevention, early detection, and therapeutic strategies, its global incidence continues to rise, and survival outcomes remain highly heterogeneous across populations and tumor types. [1,2] In the United States, gains in cancer survival have been partially offset by the growing burden of population aging, obesity, and metabolic dysfunction (factors that are now firmly established as major determinants of both cancer risk and prognosis) . [1,3] Among these, insulin resistance represents a central  \npathophysiological hallmark of metabolic dysfunction, mechanistically linking obesity and type 2 diabetes mellitus (T2DM) to a pro-tumorigenic milieu characterized by hyperinsulinemia, chronic low-grade inflammation, and dysregulation of insulin/ insulin-like growth factor signaling. This altered metabolic environment promotes cellular proliferation while inhibiting apoptosis, thereby facilitating tumor initiation and progression. [4–6]  \nA substantial body of epidemiological evidence has demonstrated that metabolic syndrome, hyperinsulinemia, and T2DMare associated with increased incidence and poorer survival across multiple malignancies, including colorectal, pancreatic, hepatic, endometrial, and postmenopausal breast cancers. [1,5,6] However,  \nThis study was funded by the Henan Provincial Medical Science and Technology Innovation Program (Joint Construction Project) (No. LHGJ20250696).  \nThis study is a secondary analysis of de-identified public data from NHANES, for which written informed consent was obtained by the NCHS Ethics Review Committee from all participants at the time of data collection, and thus no additional informed consent was required for our analysis.  \nThe authors have no conflicts of interest to disclose.  \nAll data generated or analyzed during this study are i","cbCaitkG44SIwiDN","https://ap.wps.com/l/cbCaitkG44SIwiDN","pdf",896443,"English","# Introduction\n## Study background and rationale\n# Methods\n## Cohort, exposure definition, and follow-up\n## Statistical analyses\n# Results\n## Association between METS-IR and cancer-specific mortality\n## Effect modification by hypertension\n## Robustness checks\n# Conclusions","[{\"question\":\"What is METS-IR and how is it used in this study?\",\"answer\":\"METS-IR (metabolic score for insulin resistance) is calculated from fasting glucose, triglycerides, and other indicators.
