Primary submandibular gland tumors are relatively rare. Due to its low incidence and broad spectrum phenotypic, biological and clinical heterogeneity types, a wide range of options have been developed to treat this tumor. To date, however, efficacious standard treatment regimens are lacking. Here, the authors present a case of a patient with an advanced submandibular gland tumor. Histological and imaging results diagnosed the case as stage IV submandibular gland adenocarcinoma with multiple metastases. The patient was subjected to systemic platinum-based chemotherapy combined with sintilimab. A primary lesion complete response was observed after six cycles of treatment. This case affirms the efficacy of the PD-1 inhibitor sintilimab combined with platinum-based chemotherapy as a first-line treatment for advanced submandibular gland tumors.
