ABSTRACT
OBJECTIVE: To evaluate the outcomes in patients undergoing surgery for metastatic renal cell carcinoma (RCC) to the pancreas. MATERIAL AND METHODS: A retrospective analysis included 54 patients with pancreatic metastases (PM) of RCC who underwent surgical treatment at the Blokhin National Cancer Medical Research Center and Vishnevsky National Medical Research Center of Surgery in 1995-2018. PM were synchronous in 6 (11%) patients and metachronous in 48 (89%) patients. Solitary metastases were identified in 35 (65%), single metastases - in 14 (26%), multiple metastases - in 5 (9%) patients. Thirty (56%) patients had isolated PM, 24 (44%) patients - PM associated with another metastatic site. The following surgical procedures were performed: distal pancreatectomy (n=30, 55%), pancreatoduodenectomy (n=12, 21%), total pancreatectomy (n=6, 12%), pancreatic head resection (n=3, 6%), middle-preserving pancreatectomy (n=1, 2%), middle pancreatectomy (n=1, 2%), cryosurgical destruction of tumor (n=1, 2%). RESULTS: Median blood loss was 950 ml (interquartile range 400-1800 ml). Postoperative complications occurred in 52% patients. The 90-day mortality rate was 6%, overall 5-year survival 74±7%, median - 84 months. CONCLUSION: Surgery is associated with an acceptable perioperative complications and long-term survival in patients with synchronous and metachronous, solitary and multiple PM of RCC, including cases of extrapancreatic disease. This approach may be considered as a management option in these patients.
