Synchronous primary gastric cancer and renal cell carcinoma: A case report and literatures review

AbstractA 73-year-old woman was admitted and treated because of epigastric fullness, palpitation, and tarry stool for 2 days. Gastric cancer was found via panendoscopy. A preoperative abdominal computed tomographic scan revealed a hypervascular mass in the left kidney; renal cell carcinoma (RCC) was the initial impression. A concomitant surgery for subtotal gastrectomy and radical left nephrectomy was performed. The pathological examination confirmed gastric adenocarcinoma (T2a) and RCC (T2b). Convalescence was uneventful and she was discharged in stable condition. There was no evidence of tumor recurrence at a 20-month follow-up examination. Elderly people with early gastric cancers have a relative higher probability of developing a synchronous tumor than younger people. The incidence of synchronous gastric cancer and RCC is quite low, and concomitant surgery is rare. Surgeons need to be aware of the possibility of a synchronous second primary cancer when the initial gastric cancer is diagnosed. A concomitant surgery for gastrectomy and radical nephrectomy can be safely performed in selected patients, which can achieve feasible oncological control
