Abstract
AIM: We examined the effect of diabetes on survival in patients with lymphoma and the effect of lymphoma on glycemic control. PATIENTS & METHODS: Patients with lymphoma with and without diabetes (2005-2016) were retrospectively identified and matched 1:1. Overall survival and progression-free survival were estimated by the Kaplan-Meier method. Hemoglobin A(1c) (HbA(1c)) and glucose levels during the year after cancer diagnosis were compared by mixed models. RESULTS: For patients with diabetes, mean HbA(1c) during the year after lymphoma diagnosis was 6.7%. Estimated 5-year progression-free survival for patients with versus without diabetes was 63% (95% CI: 53-76%) versus 58% (95% CI: 46-71%) (p = 0.42). CONCLUSION: Lymphoma and its treatment did not affect glycemic control. Diabetes did not decrease lymphoma-specific survival.
