Sumario: | Brain metastasis is a rare refractory event in patients with urothelial carcinoma. Platinum-based chemotherapy is the recommended first-line standard therapy for all metastasis urothelial carcinoma patients eligible for cisplatin or carboplatin. Patients ineligible for platinum may receive immunotherapy. No clear evidence exists that UC with brain metastasis is sensitive to immunotherapy, and the optimal treatment for patients with BM is uncertain. We evaluated the safety and efficacy of combined immunotherapy and antivascular therapy in an elderly patient with urothelial carcinoma with brain metastasis, and summarize the currently available evidence. First, she underwent a left nephrectomy and left ureterectomy and recovered well postoperatively. The postoperative pathologic findings were consistent with urothelial carcinoma. Approximately 2 years later, the patient developed impaired limb movement on the right side and underwent MRI, which revealed lesions in the left frontal lobe and suggested brain metastasis. The brain metastasis responded to local radiotherapy but progressed again in a short time. Then, the patient was administered toripalimab at 240 mg combined with bevacizumab at 300 mg every 3 weeks. After 1cycle of treatment, the patient achieved a quick response, and symptoms improved significantly. Repeat evaluation imaging demonstrated that the lesions in the brain and lung were significantly smaller and evaluation showed partial response. The treatment was well tolerated and the patient remained in partial response until the last follow-up by July 2022, 6 months after the initiation of treatment. This case suggests that immune checkpoint blockade combined with antivascular therapy might be a new possibility for patients with metastatic urothelial carcinoma, including brain metastases. |
