Survival and glycemic control in patients with co-existing squamous cell carcinoma and diabetes mellitus
Abstract
Aim: This study examined the impact of diabetes mellitus (DM) on survival in squamous cell carcinoma (SCC) patients, and the impact of SCC on glycemic control. Materials & methods: Patients with newly diagnosed SCC with and without DM were matched 1:1 (2007–2017). Overall survival and recurrence-free survival were estimated using the Kaplan–Meier method. Hemoglobin A1c (HbA1c) and glucose level during the year following cancer diagnosis were compared using mixed models. Results: HbA1c decreased over time in DM patients (p = 0.04). The 5-year overall survival was 61% in DM patients, compared with 78% in patients without DM (p = 0.004). Conclusion: The presence of co-existing DM adversely impacted survival in patients with SCC. SCC did not affect glycemic control.
