AbstractOBJECTIVES
This study investigated the risk of developing and dying from all types of cancer, as well as cancer-specific mortality, in women diagnosed with prediabetes and diabetes.METHODSWe included women aged ≥40 years who underwent cancer screening from 2009 to 2014 with follow-up until 2020. Diabetes status was determined based on fasting plasma glucose levels, self-reported history of diabetes, and the use of antidiabetic medication. We quantified the risk of cancer and mortality in the prediabetes and diabetes groups, relative to the normoglycemia group, by calculating adjusted hazard ratios (aHRs).RESULTSThe study included 8,309,393 participants with a mean age of 52.7±9.7 years. Among these participants, 522,894 cases of cancer and 193,283 deaths were detected. An increased risk of cancer was observed in both the prediabetes group (aHR, 1.03; 95% confidence interval [CI], 1.02 to 1.04) and the diabetes group (aHR, 1.13; 95% CI, 1.12 to 1.14). The highest risk was identified in those with diabetes who developed liver (aHR, 1.72; 95% CI, 1.66 to 1.79), pancreatic (aHR, 1.68; 95% CI, 1.60 to 1.76), and gallbladder cancer (aHR, 1.43; 95% CI, 1.36 to 1.51). Women with prediabetes and diabetes exhibited a 1.07-fold (95% CI, 1.05 to 1.08) and 1.38-fold (95% CI, 1.36 to 1.41) increased risk of death from cancer, respectively.CONCLUSIONSBoth prediabetes and diabetes were associated with an elevated risk of cancer, as well as an increased risk of death from cancer, in middle-aged Korean women. However, the degree of risk varied depending on the specific site of the cancer. -

40세 이상의 중년 여성에서 당뇨 또는 당뇨 전 단계는 암 발생 위험과 암으로 인한 사망위험을 증가시킴. 암 종별로는 위암, 대장암, 직장암, 간암, 담낭암, 췌장암, 유방암, 자궁경부암, 자궁암, 신장암, 방광암의 발생 위험이 증가한 반면, 갑상선암의 발생 위험은 감소하였음. 거의 대부분의 암종에서 당뇨는 암으로 인한 사망위험을 증가시킴Key Message
Both prediabetes and diabetes were independently associated with an overall increased risk of cancer, with a stronger association with malignancies in the liver and pancreas in women. Additionally, both prediabetes and diabetes status are associated with an elevated risk of death from cancer. These findings support the need for prevention and management to reduce cancer-related burden and premature deaths due to cancer, not only in individuals with diabetes but also in those with prediabetes.
