Abstract | BACKGROUND: METHODS: RESULTS: Patients taking metformin presented with more early-stage tumors (T1 and T2) and less regional metastasis (N0; 81% metformin+ vs 50% metformin-) compared to patients with diabetes not taking metformin. At last follow-up, 76% of patients taking metformin were alive, compared to 41% for diabetics not on metformin and 51% for nondiabetics. Metformin users demonstrated increased disease-free survival (DFS) and overall survival (OS) compared with nonmetformin users and nondiabetics. CONCLUSION: Patients with diabetes taking metformin present with earlier stage disease and have more favorable clinical outcomes when compared to their diabetic counterparts and nondiabetics. Combined with previously published retrospective studies, our results suggest that prospective clinical trials evaluating the role of metformin in head and neck cancer are warranted.
