Surgical treatment of hepato-pancreatic metastases from renal cell carcinoma

Background The role of surgical treatment of hepato-pancreatic metastases from renal cell carcinoma is still under discussion. Material and methods We report about 52 patients of whom 33 underwent surgery for liver metastases and 19 for pancreatic metastases from 1995 to 2018. Results The 5-year survival rate of all patients with partial liver resection was statistically significantly lower (38%, median survival time 34 months) than with pancreas resection (69%, median survival time 69 months, p = 0.017). Of the patients 21 survived the resection of metastases longer than 5 years and 4 patients longer than 10 years. In R0 resected patients, recurrences were observed in 13 cases after liver resection and in 9 cases after pancreas resection. The cumulative recurrence rate after 5 years was 38% for the liver and 57% for the pancreas. In R0 partial liver resections, an interval Conclusion In spite of high recurrence rates, surgical treatment for hepato-pancreatic metastases from renal cell carcinoma yielded very good long-term results, in particular with complete resection of solitary metachronous metastases. Repeated surgery for completely resectable metastases, resulted in long tumor-free intervals and thus contributed to good long-term results.
