Integrating traditional Chinese medicine with Western medicine in treating solitary gastric metastasis from renal cell carcinoma: a case report and literature review

The metastasis of renal cell carcinoma (RCC) to the stomach is a rare event, and in many cases, it indicates a poor prognosis.In this paper, we present the case of a 76-year-old female patient who underwent a right nephrectomy.Approximately two years later, the patient had an endoscopic resection for gastric metastasis and was subsequently treated with Chinese herbal medicines.Remarkably, this patient has remained tumor-free for over a decade.Furthermore, we conducted a comprehensive literature review of all documented cases involving individuals with RCC who developed isolated gastric metastasis.Surgical intervention and endoscopic treatment for gastric metastasis are both recommended, as evidence suggests they can extend overall survival.
