Efficacy of first-line immunization combined with antiangiogenesis treatment and chemotherapy for the treatment of tongue cancer: A case report

Abstract

Background: There is currently no uniform and effective treatment for patients with locally advanced oral cancer who cannot tolerate surgery or radiotherapy. The prognosis of oral cancer patients with lymph node metastasis is very poor, but the clinical treatment of such patients faces certain challenges. Patients and methods: Case 1 was a 59-year-old patient with tongue cancer (cT 3 N x M 0 G 2) who refused radiotherapy because of a history of leukoderma. After evaluation of disease condition, a 4-drug combination therapy of toripalimab + anlotinib + nabpaclitaxel + carboplatin was administered. Case 2 was a 55-year-old patient with tongue cancer (cT 3 N 2 M 0 G 1) who could not receive radiotherapy because of a medical history of cervicofacial burns. After disease evaluation, toripalimab + anlotinib + docetaxel + carboplatin combination therapy was administered. Case summary: Both patients did not experience any adverse reactions during treatment and achieved a complete response after 2 cycles of treatment. Their progression-free survival is currently 6 and 8 months, respectively, and they are in sustained remission. Conclusion: Currently, the efficacy of immune checkpoint inhibitors targeting programmed death-1 as a first-line treatment of inoperable and non-radiatable locally advanced oral cancer is unknown. Here, we describe 2 cases of locally advanced oral cancer treated with first-line immune checkpoint inhibitors in combination with targeted therapy and chemotherapy. This approach was successful in these patients, but a larger sample size is required to verify our findings.
