Long-term All-Cause Mortality in Cancer Patients With Preexisting Diabetes Mellitus: A Systematic Review and Meta-analysis
Open accessAbstract
CONTEXT: Diabetes mellitus appears to be a risk factor for some cancers, but the effect of preexisting diabetes on all-cause mortality in newly diagnosed cancer patients is less clear. OBJECTIVE: To perform a systematic review and meta-analysis comparing overall survival in cancer patients with and without preexisting diabetes. DATA SOURCES: We searched MEDLINE and EMBASE through May 15, 2008, including references of qualifying articles. STUDY SELECTION: English-language, original investigations in humans with at least 3 months of follow-up were included. Titles, abstracts, and articles were reviewed by at least 2 independent readers. Of 7858 titles identified in our original search, 48 articles met our criteria. DATA EXTRACTION: One reviewer performed a full abstraction and other reviewers verified accuracy. We contacted authors and obtained additional information for 3 articles with insufficient reported data. RESULTS: Studies reporting cumulative survival rates were summarized qualitatively. Studies reporting Cox proportional hazard ratios (HRs) or Poisson relative risks were combined in a meta-analysis. A random-effects model meta-analysis of 23 articles showed that diabetes was associated with an increased mortality HR of 1.41 (95% confidence interval [CI], 1.28-1.55) compared with normoglycemic individuals across all cancer types. Subgroup analyses by type of cancer showed increased risk for cancers of the endometrium (HR, 1.76; 95% CI, 1.34-2.31), breast (HR, 1.61; 95% CI, 1.46-1.78), and colorectum (HR, 1.32; 95% CI, 1.24-1.41). CONCLUSIONS: Patients diagnosed with cancer who have preexisting diabetes are at increased risk for long-term, all-cause mortality compared with those without diabetes.

TL;DR
In cancer patients with preexisting diabetes, pooled long-term all-cause mortality was significantly higher than in normoglycemic patients (HR 1.41; 95% CI, 1.28-1.55) across 23 studies. Significant site-specific increases were found for endometrial, breast, and colorectal cancers.
Key findings
- Meta-analysis of 23 studies found preexisting diabetes associated with increased all-cause mortality after cancer diagnosis: HR 1.41 (95% CI, 1.28-1.55).
- Site-specific pooled estimates were significant for endometrium (HR 1.76; 95% CI, 1.34-2.31), breast (HR 1.61; 95% CI, 1.46-1.78), and colorectum (HR 1.32; 95% CI, 1.24-1.41).
- Nonsignificant increases were reported for prostate (HR 1.51; 95% CI, 0.94-2.43), gastric (HR 1.36; 95% CI, 0.92-2.01), hepatocellular (HR 1.30; 95% CI, 0.99-1.70), lung (HR 1.15; 95% CI, 0.99-1.34), and pancreatic cancer (HR 1.09; 95% CI, 0.70-1.69).
- Sensitivity analyses excluding univariate estimates gave HR 1.40 (95% CI, 1.29-1.52); excluding analyses not adjusting/restricting for age and disease severity gave HR 1.42 (95% CI, 1.28-1.56). No significant publication bias was observed by Begg test (P = .92) or Egger plot (P = .34).
Methods
- Systematic review and meta-analysis searching MEDLINE and EMBASE through May 15, 2008; 7,858 titles identified, 48 articles met criteria for the systematic review of long-term all-cause mortality, and 23 studies met criteria for meta-analysis.
- Included English-language human original investigations with at least 3 months follow-up; meta-analysis required risk estimates (HR/RR) and precision estimates, with authors contacted for additional data.
- Random-effects meta-analysis using DerSimonian-Laird method; heterogeneity assessed with Cochran Q and I²; publication bias assessed with Begg funnel plot and Egger plot; sensitivity analyses and nonparametric sign test performed.
Limitations
- The paper states substantial heterogeneity across studies in demographics, diabetes ascertainment, and confounder adjustment; heterogeneity was significant by Q statistic (205 on 24 df, P < .001) and I² (88.3%, P < .001).
- The paper states studies spanned many decades (published 1969-2008), follow-up time was not always reported, and differences in follow-up may limit interpretation.
- Evident from the text: 9 studies with regression models had insufficient reporting for meta-analysis, only 3 of 12 contacted authors provided additional information, and many studies did not adjust for age and cancer severity; power was low (<50%) for prostate, gastric, hepatocellular, lung, and pancreatic cancer estimates.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
