Abstract
BACKGROUND Pancreatic metastases (PM) from renal cell carcinoma (RCC) are uncommon. We herein describe the long-term outcomes associated with pancreatectomy at two academic institutions, with a specific focus on 10-year survival. METHODS This investigation was limited to patients undergoing pancreatectomy for PM between 2000 and 2008 at the University of Verona and Memorial Sloan Kettering Cancer Center, allowing a potential for 10 years of surveillance. The probabilities of further RCC recurrence and RCC-related death were estimated using a competing risk analysis (method of Fine and Gray) to account for patients who died of other causes during follow-up. RESULTS The study population consisted of 69 patients, mostly with isolated metachronous PM (77%). The median interval from nephrectomy to pancreatic metastasectomy was 109 months, whereas the median post-pancreatectomy follow-up was 141 months. The 10-year cumulative incidence of new RCC recurrence was 62.7%. In the adjusted analysis, the relative risk of repeated recurrence was significantly higher in PM synchronous to the primary RCC (sHR = 1.27) and in patients receiving extended pancreatectomy (sHR = 3.05). The 10-year cumulative incidence of disease-specific death was 25.5%. The only variable with an influence on disease-specific death was the recurrence-free interval following metastasectomy (sHR = 0.98). In patients with repeated recurrence, the 10-year cumulative incidence of RCC-related death was 35.4%. CONCLUSION In a selected group of patients followed for a median of 141 months and mostly with isolated metachronous PM, resection was associated with a high possibility of long-term disease control in surgically fit patients with metastases confined to the pancreas.

Abstract Objective Competing events are often ignored in epidemiological studies. Conventional methods for the analysis of survival data assume independent or non-informative censoring, which is violated when subjects that experience a competing event are censored. Because many survival studies do not apply competing risk analysis, we explain and illustrate in a non-mathematical way how to analyse and interpret survival data in the presence of competing events. Study Design and Setting Using dat...

Abstract Background Literature data about pancreatic resections for metastases are limited to small series, so that the role of surgery in this setting remains unclear. We herein report our experience from a tertiary care center, analyzing the outcomes of patients who underwent pancreatic resections for metastases and discussing the role of surgical resection in their management. Materials and methods From January 1999 to January 2019, 26 patients underwent pancreatic resections for metastases f...

Renal cell carcinoma (RCC) is characterized by a particularly broad metastatic swath, and, enigmatically, when the pancreas is a destination, the disease is associated with improved survival. Intrigued by this observation, we sought to characterize the clinical behavior, therapeutic implications, and underlying biology. While pancreatic metastases (PM) are infrequent, we identified 31 patients across 2 institutional cohorts and show that improved survival is independent of established prognostic...

Abstract Background Renal cell carcinoma (RCC) can lead to secondary pancreatic tumors even years after nephrectomy was performed. Surgical resection in selected patients shows appropriate survival rates. Methods A systematic review was performed following PRISMA guidelines. This review finished in May 2019 and included patients with resected pancreatic metastasis(es). The main purpose was to evaluate the results of surgical resection of pancreatic tumors secondary to kidney cancer. Results Afte...

Background Metastatic lesion to the pancreas accounts for approximately 2% of pancreatic neoplasms. There is no prospective, randomized or case-controlled study evaluating the role of pancreatic metastasectomy.

We investigated time-dependent changes in the relapse features of renal cell carcinoma (RCC) after curative surgery. Between 1985 and 2015, 1398 patients with RCC (1226 clear cell RCC, 89 papillary RCC, and 53 chromophobe RCC) underwent curative surgery at Yokohama City University Hospital and its affiliated hospitals. We retrospectively reviewed the clinicopathologic factors of patients with relapse after surgery. Median follow-up was 56.3 months. Recurrence occurred in 245 patients (217 clear ...

: Although mortality rates after pancreatectomy have decreased, the incidence of postoperative morbidity remains high. The major procedure-related complications are pancreatic fistula, delayed gastric emptying, and postpancreatectomy hemorrhage. The International Study Group of Pancreatic Surgery defined leading complications in a standardized fashion, allowing unbiased comparison of operative results and management strategies. Risk factors for postoperative complications have been investigated ...

Pancreatic metastases from renal cell carcinoma are uncommon and their prognostic significance is not well defined. In this analysis we evaluated the outcome of patients with pancreatic metastases treated with either targeted therapies or local treatment to the pancreas. Patients with pancreatic metastases from renal cell carcinoma treated between 1993 and 2014 were identified from 11 European centers. Clinical records were retrospectively reviewed. Kaplan-Meier method and log-rank test were use...
