Introduction:
Sodium-glucose cotransporter-2 inhibitors (SGLT2is) are widely prescribed for type 2 diabetes mellitus (T2DM) and may confer hepatoprotective effects. This study investigated their association with hepatocellular carcinoma (HCC) risk compared with other antidiabetic medications.
Methods:
We conducted a retrospective cohort study using the electronic health records from Mass General Brigham (Boston, USA) and Asan Medical Center (Seoul, Korea) from 2013 to 2024. Adults with T2DM newly initiating SGLT2i, dipeptidyl peptidase-4 inhibitor (DPP4i), glucagon-like peptide-1 receptor agonist (GLP-1RA), or sulfonylureas were included. A 6-month landmark analysis was used to minimize early event bias. Inverse probability weighting combined with Fine-Gray competing risk models estimated subdistribution hazard ratios (SHRs) for incident HCC, accounting for transplant and death as competing events.
Results:
After weighting, data from 6,733 SGLT2i, 4,495 GLP-1RA, 23,229 DPP4i, and 17,034 sulfonylurea initiators were analyzed. Over a median follow-up of 3.9 years (277,155 person-years), 623 HCC cases occurred. SGLT2i use was associated with significantly lower HCC risk vs sulfonylureas (SHR 0.44, 95% confidence interval [CI]: 0.25-0.79) and DPP4i (SHR 0.53, 95% CI: 0.30-0.93). The comparison with GLP-1RA showed comparable risk (SHR 0.87, 95% CI: 0.40-1.91). Subgroup analyses demonstrated consistent protective associations of SGLT2i in patients aged 65 years and younger, men, and those with chronic liver disease. Sensitivity analyses, including 12-month landmark analysis and adjustments for additional confounders, confirmed robustness of findings.
Discussion:
SGLT2 inhibitor therapy was associated with reduced risk of HCC compared with DPP4 inhibitors and sulfonylureas, supporting their potential chemopreventive role in patients with T2DM.
Insights
Sodium-glucose cotransporter-2 inhibitors (SGLT2is) show reduced hepatocellular carcinoma (HCC) risk in type 2 diabetes mellitus (T2DM) patients. This finding supports SGLT2is as a potential chemopreventive therapy for HCC in T2DM.
Area of Science:
- Endocrinology
- Hepatology
- Oncology
Background:
- Sodium-glucose cotransporter-2 inhibitors (SGLT2is) are common type 2 diabetes mellitus (T2DM) treatments.
- Potential hepatoprotective effects of SGLT2is warrant investigation for liver cancer risk.
Purpose of the Study:
- To evaluate the association between SGLT2 inhibitor use and hepatocellular carcinoma (HCC) risk.
- To compare HCC risk among T2DM patients initiating SGLT2i versus other antidiabetic medications.
Main Methods:
- Retrospective cohort study utilizing electronic health records from US and Korean medical centers (2013-2024).
- Included adults with T2DM initiating SGLT2i, DPP4i, GLP-1RA, or sulfonylureas.
- Used 6-month landmark analysis and inverse probability weighting with Fine-Gray competing risk models.
Main Results:
- SGLT2i use was linked to significantly lower HCC risk compared to sulfonylureas (SHR 0.44) and DPP4 inhibitors (SHR 0.53).
- HCC risk was comparable between SGLT2i and GLP-1RA users (SHR 0.87).
- Protective effects were consistent across subgroups, including younger patients, males, and those with chronic liver disease.
Conclusions:
- SGLT2 inhibitor therapy is associated with a reduced risk of HCC in T2DM patients.
- Findings suggest a potential chemopreventive role for SGLT2 inhibitors against HCC.
