Survival Data Justifies Resection for Pancreatic Metastases
Annals of Surgical Oncology, 2009
Background. Pancreatic metastases are uncommon and little is known about the oncologic outcome after resection or prognostic parameters. This study was designed to evaluate perioperative and follow-up results after resection for pancreatic metastases and to define prognostic factors. Methods. From a prospective database, all consecutive resections performed at our institution for pancreatic metastases between October 2001 and July 2008 were identified. Clinicopathological details, perioperative, and follow-up results were analyzed. Uni-and multivariate analysis were performed to identify parameters associated with overall and disease-free survival. Results. Forty-four resections were performed for pancreatic metastases. Primary tumors included 31 (70%) renal cell carcinomas (RCC) and 13 other primary tumors. Morbidity was 33% and mortality 4.4%. Pancreatic metastases occurred after a median interval of 6.9 years after resection of the primary tumor. Twenty-five patients (57%) had additional extrapancreatic disease. With a median follow-up of 32.1 months, overall 3-and 5-year survivals were 70.2% and 56.8%, disease-free 3-and 5year survivals were 37.2% and 33%, respectively. Patients with isolated pancreatic metastases had an overall 3-and 5year survival of 85.6% and 74.9%. Additional extrapancreatic disease, a disease-free interval of less than 36 months, and non-RCC entity were associated with shorter overall survival. Previous recurrence, non-RCC primary tumors, and a disease-free interval of less than 36 months were associated with shorter disease-free survival. Conclusions. Resection for pancreatic metastases can be performed safely and with good follow-up results and can be recommended as part of an interdisciplinary treatment. Especially in patients with isolated pancreatic metastases, long-term survival can be expected.
Safety and Efficacy of Surgery for Metastatic Tumor to the Pancreas: A Single-Center Experience
Journal of Clinical Medicine
Pancreatic metastases from other neoplasms are rare. The role of surgery for this clinical entity is unclear. The aim of this study was to investigate the role of resection in patients with pancreatic secondary lesions. We observed 44 patients with pancreatic metastases from other tumors. Renal cell carcinoma was the most common primary tumor (n = 19, 43.2%). Thirty-seven patients underwent surgery, and pancreatic resection with curative intent was feasible in 35 cases. Fifteen patients (43.2%) experienced major postoperative complications (Clavien-Dindo > 2), and postoperative mortality rate was 5.4%. The median overall survival and disease-free survival were 38 (range 0–186) and 11 (range 0–186) months, respectively. Overall survival and disease-free survival were significantly longer for pancreatic metastases from renal cell carcinoma when compared to other primary tumors. Multivariate analysis confirmed a pathological diagnosis of metastasis from RCC as an independent prognos...
Pancreatic Resections for Metastatic Disease
Advances in Pancreatic Cancer, 2018
Although the incidence of metastases to the pancreas from various primaries is very low, these lesions are usually being described as part of the systemic recurrence of different malignancies, in certain cases isolated pancreatic metastases might be encountered. When it comes to the malignancies, which might lead to the apparition of pancreatic metastases, the most common origins have been reported to be renal cell carcinoma, colon cancer, ovarian cancer and melanomas. In certain cases, patients with pancreatic metastases might be submitted to surgery with curative intent. However, it should not be omitted that pancreatic resections can be associated with higher rates of perioperative morbidity; therefore, a precise selection of the cases that are considered suitable for such procedures is mandatory. It seems that the best results in regard with long-term survival are expected in cases with isolated pancreatic metastases as well as in cases with limited extrapancreatic lesions, amenable to complete cytoreductive surgery. This chapter reviews the most important studies conducted on the theme of pancreatic resections for metastatic disease from various primaries.
Metastatic Tumors in the Pancreas in the Modern Era
Journal of the American College of Surgeons, 2010
BACKGROUND-Tumors metastasizing to the pancreas are rare, and published series are limited by few patients treated for extended periods of time. Renal cell cancer (RCC) is the most common primary tumor metastasizing to the pancreas. Our aim was to describe the clinicopathologic characteristics and patient outcomes in a modern series of patients who underwent metastasectomy, with an emphasis on RCC.
Resection of renal metastases to the pancreas: a surgical challenge
HPB: Official Journal of The International Hepato Pancreato Biliary Association, 2003
Background Metastasis to the pancreas from renal cell carcinoma (RCC) is distinctly uncommon. Most cases are detected at an advanced stage of the disease and are thus unsuitable for resection. A solitary RCC metastasis to the head of pancreas is rarely encountered and, although it is potentially amenable to surgical resection, surgeons may be hesitant to perform pancreatoduodenectomy. Cases outlines Two patients with a solitary RCC metastasis to the head of pancreas were treated by pancreatoduodenectomy, while a third with multiple RCC metastases declined any treatment. Two of the patients were asymptomatic, and one presented with anaemia and mild abdominal pain. Computed tomography (CT) and angiography were used to exclude other metastases and to assess resectability of the pancreatic tumour. All three patients are still alive, those with resectable disease at 2 years and 9 years and the one with irresectable disease at 4 years. Discussion Isolated RCC metastasis to the pancreas is a rare event. Patients present either on follow-up imaging or with symptoms such as mild abdominal pain, weight loss, jaundice, anaemia or gastrointestinal bleeding (whether occult or overt). Dynamic spiral CT can visualise the tumour and exclude distant metastasis. Angiography often reveals a highly vascularised tumour and will help to assess resectability. In the absence of widespread disease, pancreatic resection can provide long-term survival in metastatic RCC, although few cases have been reported with lengthy follow-up. The prognosis is better than for pancreatic adenocarcinoma.

Backgrounds/Aims: Metastasis in the pancreatic gland is infrequent, representing between 2-5% of the tumors that affect this organ. However, secondary lesions of clear cell renal carcinoma (CCRC) can occur mainly in this location and it is frequently the only site of dissemination. Treatment of choice is resection in surgically fit patients, as it has been shown that it improves the quality of life and prognosis substantially. We retrospectively reviewed the clinical data of patients with pancreatic resections for metastatic CCRC since there are no reports of the treatment modality of this singular entity in Argentina. Methods: Retrospective cohort analysis over a 10-year period including eight patients who underwent pancreatic resection for metastatic CCRC. Results: 75% of patients were male with an average age of 65.5 years. The pancreatic surgery occurred at a median time of 9.2 years (1-24.8) from the renal operation. The pancreatic lesions were mostly solitary and asymptomatic. A pancreaticoduodenectomy (PD) was performed in 4 patients (50%). Distal pancreatectomy (DP) was performed in 3 patients (37.3%) and one patient (12.5%) underwent a total pancreaticoduodenectomy. All the patients presented a confirmatory biopsy of pancreatic metastasis of CCRC. Complications were recorded in 3 patients (42.85%). No intraoperative or postoperative mortality was registered. With a median follow-up of 45 months, three patients presented recurrence at 32, 46 and 51 months, respectively. Only one patient showed death due to recurrence at 7.8 month. Conclusions: CCRC pancreatic metastases treated surgically have a low morbidity and mortality rate in high volume centers, showing excellent long-term survival.

Introduction. Metastatic tumors in the pancreas constitute a small (2–5%), but steadily growing percentage of all neoplasms of this organ. The aim of the study was to analyze the surgical treatment of metastases in the pancreas, in particular its effectiveness and the risk of surgical complications. Material and methods. The retrospective analysis was performed on 21 patients treated surgically in three surgical centers. This group included 16 women (76%) and 5 men (24%). The median age at the time of diagnosis of the underlying disease was 55.5 years (41–71). We analyzed the location of secondary lesions, their size, number, type and radicality of surgical intervention, histopathological diagnosis of the disease, as well as the occurrence of postoperative complications. Results. The starting point for metastatic lesions in 16 patients (76%) was renal cell carcinoma (RCC), in other cases — skin melanoma, eyeball melanoma, adenocarcinoma of the rectum, non-small-cell bronchi carcinom...

Background: Unlike primary pancreatic carcinoma, metastases to the pancreas are rare, and their resection may be performed as palliative treatment. The aim of this study was to review our experience with the operative management of pancreatic metastases. Materials and Methods: Between January 1994 and December 2004 13 patients (nine women and four men; median age: 59 years; range: 36-79 years) were admitted to our institution with metastatic lesion to the pancreas. The clinical features of the treatment and results were examined. Results: Primary tumors were renal cell carcinoma (n = 5), lobular carcinoma of the breast (n = 3), endometrioid carcinoma of the ovary (n = 1), colonic adenocarcinoma (n = 1), jejunal leiomyosarcoma (n = 1), melanoma (n = 1), and non-small-cell lung cancer (n = 1). The median interval between primary tumor and pancreatic metastases was 36 months (range: 5-192 months). Six patients (46%) were asymptomatic, while the other seven patients presented with jaundice, pain, and duodenal obstruction. Two patients with extrapancreatic disease underwent palliative surgery, and the remaining 11 patients underwent operative procedures that included seven pancreaticoduodenectomy and four distal pancreatectomies with splenectomy. Postoperative mortality was nil, and the morbidity rate was 30%. The two patients who underwent palliative surgery died after 7 and 9 months, respectively. The median survival of the resected patients was 26 months (range: 13-95 months). Five patients died of disease, eight are alive at the time of this report. Conclusion: A trend towards improved survival, even if not statistically significant, was observed in the renal carcinoma patients reported here. Surgical resection can be performed safely in selected patients with isolated metastases to the pancreas, achieving long-term survival as well as good palliation. P ancreatic metastases from a non-pancreatic primary tumor are uncommon and account for approximately 2% of all pancreatic neoplasms. 1 The reported incidence of these lesions in autopsy studies ranges from 1.6 to 11% in the context of widespread metastatic dis-ease, while the clinical occurrence of isolated metastasis to the pancreas is even less frequent. 2-4 Renal cell carcinoma, melanoma, and breast, lung, and colonic cancer are tumors that metastasize more frequently to the pancreatic gland. 4-6 Metastases to the liver, lung, and brain from several types of tumors, such as colorectal cancer, sarcoma, and renal cell carcinoma, are amenable to Correspondence to: Stefano
Pancreatic resections for advanced M1-pancreatic carcinoma: the value of synchronous metastasectomy
HPB surgery : a world journal of hepatic, pancreatic and biliary surgery, 2010
For M1 pancreatic adenocarcinomas pancreatic resection is usually not indicated. However, in highly selected patients synchronous metastasectomy may be appropriate together with pancreatic resection when operative morbidity is low. From January 1, 2004 to December, 2007 a total of 20 patients with pancreatic malignancies were retrospectively evaluated who underwent pancreatic surgery with synchronous resection of hepatic, adjacent organ, or peritoneal metastases for proven UICC stage IV periampullary cancer of the pancreas. Perioperative as well as clinicopathological parameters were evaluated. There were 20 patients (9 men, 11 women; mean age 58 years) identified. The primary tumor was located in the pancreatic head (n = 9, 45%), in pancreatic tail (n = 9, 45%), and in the papilla Vateri (n = 2, 10%). Metastases were located in the liver (n = 14, 70%), peritoneum (n = 5, 25%), and omentum majus (n = 2, 10%). Lymphnode metastases were present in 16 patients (80%). All patients recei...
