Background: The management of locally advanced oral cavity squamous cell carcinoma (LA-OCScc) in elderly patients with multiple comorbidities is difficult.
Case: We report the case of an elderly patient with buccal mucosal squamous cell carcinoma as well as chronic renal dysfunction, hepatic cirrhosis, rheumatoid arthritis, and metachronous diffuse large B-cell lymphoma. We performed radiation therapy (a total dose of 70 Gy in 35 fractions) and six cycles of intra-arterial chemotherapy with 40 mg/m2 cisplatin per week. After treatment, the tumor completely disappeared, and there was no recurrence or deterioration of comorbidities during the 12-month follow-up period.
Conclusion: Intra-arterial chemoradiotherapy may be a good treatment option for LA-OCScc in elderly patients with multiple comorbidities.
