Background:
As one of the most common types of primary bone sarcomas in adolescents and young adults, osteosarcoma has a high probability of local invasion and distant metastasis with a poor prognosis.
Case Presentation:
Here, we report the case of a 34-year-old patient with advanced metastatic osteosarcoma. Considering the high expression of PD-L1 and the inability of the patient to tolerate chemotherapy, anti-PD-1 antibody (sintilimab 200 mg, q3w) and anti-angiogenesis drug (anlotinib 8 mg D1-14, q3w) were administered. The metastatic lesions were treated with local radiotherapy. The patient obtained an 11.7-month-sustained remission period, and he also enjoyed a better quality of life.
Conclusion:
This case demonstrates that sintilimab plus anlotinib may be a feasible treatment regimen for osteosarcoma patients.
