Rationale:
Renal clear cell sarcoma is a rare and highly invasive malignant renal tumor that easily relapses after treatment. Recurrent recurrent clear cell carcinoma (CCSK) responds poorly to chemotherapy and has no established standardized treatment, and need to be explored potentially useful treatments.
Patient concerns:
A 18-years-old patient with renal clear cell sarcoma recurrence after open radical nephrectomy.
Diagnosis:
Recurrent clear cell sarcoma.
Interventions:
After chemotherapy alone failed, the patient received 6 courses of anlotinib combined with chemotherapy. The tumor had significantly reduced in size and the recurrent tumor and part of the liver were resected.
Outcomes:
No tumor recurrence or metastasis was detected during the follow-up 8 months after the operation.
Lessons:
This is the first report describing the use of anlotinib in treating CCSK. We believe that anlotinib combined with chemotherapy may be a useful treatment option for patients with recurrent CCSK.
BackgroundRenal clear cell sarcoma (CCSK) is a rare and highly invasive malignant renal tumor that easily relapses after treatment. Recurrent CCSK responds poorly to chemotherapy. Therefore, a combination of effective targeted drugs has become an urgent need for the treatment of recurrent CCSK.Case presentationHerein, we report on a patient with CCSK recurrence after surgery who responded well to neoadjuvant targeted therapy combined with chemotherapy. The patient received 6 courses of neoadjuvant targeted therapy combined with chemotherapy. After treatment, the tumor had significantly reduced in size and the recurrent tumor and part of the liver were resected. No tumor recurrence or metastasis was found during follow-up 3 months after the operation.ConclusionsWe believe that targeted therapy combined with chemotherapy can be a treatment option for patients with recurrent CCSK as it provides an opportunity for surgical resection of the tumor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
