Abstract
A meta-analysis of 1470 isolated pancreatic metastases of renal cell carcinoma revealed, that, in addition to the unusual exclusive occurrence of pancreatic metastases and the favourable treatment results, the isPMRCC is characterised by further peculiarities of the clinical course: The lack of prognostic significance of volume and growth rate dependent risk factors and the independence of treatment results from standard or local resections. As an explanation for all these peculiarities, according to today's knowledge, a strong acting seed and soil mechanism can serve, which allows embolized tumour cells to grow to metastases only in the pancreas, and prevents them definitively or for years in all other organs. The good prognosis affects not only isolated PM, but also multi-organ metastases of the RCC, in which the additional occurrence of PM is also associated with a better prognosis. Genetic studies revealed specific changes in cases of PM of RCC: Lack of loss of 9p21.3 and 14q31.2, which are otherwise specific gene mutations at the onset of generalization, a low weight genome instability index, i.e., high genetic stability, and a low rate of PAB1 and a high rate of BPRM1 alterations, which signal a more favourable course. The cause of pancreatic organotropism in isPMRCC is still unclear, so only those factors that have been identified as promoting organotropism in other, more frequent tumour entities can be presented: Formation of the pre-metastatic niche, chemokine receptor-ligand mechanism, ability to metabolic adaptation, and immune surveillance.

Isolated Pancreatic Metastases of Renal Cell Cancer: Genetics and Epigenetics of an Unusual Tumour Entity. Cancers (Basel) 2022; 14:cancers14061539. [PMID: 35326690 PMCID: PMC8945920 DOI: 10.3390/cancers14061539] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2022] [Accepted: 03/14/2022] [Indexed: 12/16/2022] Open
Abstract
Isolated pancreatic metastases of renal cell carcinoma (isPMRCC) are a rare manifestation of metastatic renal cell carcinoma (mRCC) characterized by two peculiarities: (1). The definite or at least long-term exclusive occurrence of metastases in the pancreas and (2). an unusual low tumour aggressiveness with slow tumour progression and consecutive, good treatment results. According to current knowledge, the exclusive occurrence of pancreatic metastases is due to a highly specific and highly selective seed and soil mechanism, which does not allow metastases settlement outside the pancreas, and whose detailed genetic/epigenetic causes are not yet elucidated. Recent studies have shed light on some of the pathways involved for the protracted course of the disease and highlighted a special genetic profile (lack of loss of 9p, lower weight genome instability index, low frequency of BAP1 alterations, and a high frequency of PBRM1 loss), which deviates from the conventional mRCC profile. Finally, the question of the reasons for the long-term relative genetic stability of the involved cell clones, which is an essential prerequisite for a favourable prognosis, remains unanswered.

Abstract
Previously documented arguments, in favor of the suspected impact of a seed and soil mechanism, in the development and progression of isolated pancreatic metastasis of renal cell carcinomas (isPM) are: (1) uniform and independent from the side of the primary tumor distribution of isPM within the pancreas and, (2) the similar survival rates for singular and multiple isPM. In addition, the present study adds new arguments that further confirm the importance of an seed and soil mechanism in isPM: (1) Within the singular isPM, the size of the metastasis does not affect the overall survival; (2) Within the group of multiple isPMs, the overall survival does not depend on the number of metastases; (3) For synchronous and metachronous isPM, survival rates are also not different, and (4) Within the group of metachronous isPM there is also no correlation between the overall survival and interval until metastases occurs. This unusual ineffectiveness of otherwise known risk factors of solid cancers can be explained plausibly by the hypothesis of a very selective seed and soil mechanism in isPM. It only allows embolized renal carcinoma cells in the pancreas to complete all steps required to grow into clinically manifest metastases. In all other organs, on the other hand, the body is able to eliminate the embolized tumor cells or at least put them into a dormant state for many years. This minimizes the risk of occult micrometastases in distant organs, which could later—after isPM treatment—grow into clinically manifest metastases, so that the prognosis of the isPM is only determined by an adequate therapy of the pancreatic foci, and prognostic factors, such as total tumor burden or interval until the occurrence of the isPM remain ineffective.

Observations on Solitary Versus Multiple Isolated Pancreatic Metastases of Renal Cell Carcinoma: Another Indication of a Seed and Soil Mechanism? Cancers (Basel) 2019; 11:cancers11091379. [PMID: 31533220 PMCID: PMC6770877 DOI: 10.3390/cancers11091379] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2019] [Revised: 09/02/2019] [Accepted: 09/04/2019] [Indexed: 12/15/2022] Open
Abstract
Isolated pancreas metastases are a rare type of metastasis of renal cell carcinoma, characterized by the presence of pancreatic metastases, while all other organs remain unaffected. In a previous study, we determined arguments from the literature which (a) indicate a systemic–haematogenic metastasis route (uniform distribution of the metastases across the pancreas and independence of the metastatic localization in the pancreas of the side of the renal carcinoma); and (b) postulate a high impact of a seed and soil mechanism (SSM) on isolated pancreatic metastasis of renal cell carcinoma (isPM) as an explanation for exclusive pancreatic metastases, despite a systemic haematogenous tumor cell embolization. The objective of the study presented was to search for further arguments in favor of an SSM with isPM. For that purpose, the factor’s histology, grading, and singular/multiple pancreas metastases were analyzed on the basis of 814 observations published up to 2018. While histology and grading allowed for no conclusions regarding the importance of an SSM, the comparison of singular/multiple pancreas metastases produced arguments in favor of an SSM: 1. The multiple pancreas metastases observed in 38.1% prove that multiple tumor cell embolisms occur with isPM, the exclusive “maturation” of which in the pancreas requires an SSM; 2. The survival rates (SVR), which are consistent with singular and multiple pancreas metastases (despite the higher total tumor load with the latter), prove that the metastasized tumor cells are not able to survive in all other organs because of an SSM, which results in identical SVR when the pancreatic foci are treated adequately.

Abstract
BACKGROUND This study examined the clinical outcome of patients with pancreatic metastases from renal cell carcinoma (RCC). METHODS A systematic literature search produced individual data for 311 surgically and 73 non-surgically treated patients with pancreatic RCC metastases. A further ten patients underwent resection at the authors' institution. RESULTS In the resected group, pancreatic metastases were solitary in 65.3 per cent, symptomatic in 57.4 per cent, and were preceded and/or accompanied by extrapancreatic disease in 22.3 per cent. Respective values in the unresected group were 59, 60 and 58 per cent. Disease-free survival rates were 76.0 and 57.0 per cent respectively at 2 and 5 years after resection, and overall survival rates were 80.6 and 72.6 per cent. The only significant risk factor for disease-free survival after pancreatic resection was extrapancreatic disease (P = 0.001), and that for overall survival was symptomatic RCC metastasis (P = 0.031). Two- and 5-year overall survival rates were 41 and 14 per cent respectively in unresected patients. CONCLUSION The actuarial 5-year overall survival rate following pancreatic surgery for RCC metastases was 72.6 per cent, as determined by pooled analysis from published series. Extrapancreatic disease was an independent risk factor for recurrence, but had no significant impact on overall survival.

Abstract
BACKGROUND Cancer metastatic to the pancreas from other primary sites is uncommon, and it has been treated with an aggressive surgical approach in fit patients when the primary tumor is controlled and the pancreas is the only site of metastatic disease. The value of pancreatic resection in this setting is unclear. The purpose of this study was to review cases of cancer metastatic to the pancreas. METHODS We reviewed our experience with cancer metastatic to the pancreas and the literature regarding resection of pancreatic metastases. Patient and tumor characteristics were summarized using descriptive statistics. RESULTS A total of 220 patients with pancreatic metastasis were analyzed. Three patients were selected from our own experience, and 217 were selected from a literature review. In the 127 patients whose symptoms were recorded at the time of presentation, the most common presenting symptoms were jaundice (n=32, 25.2%) and abdominal pain (n=25, 19.7%). In the 189 patients for whom the location of the metastasis in the pancreas was revealed, the most common location was the head of the pancreas (n=79, 41.8%). The primary tumor site was most commonly kidney (n=155, 70.5%). Surgical resection was attempted in 177 of 220 patients; 135 patients suffering from renal cell carcinoma (RCC) metastasis also underwent pancreatic resection. In the latter group, a median survival of 70 mo was seen, as well as 78% and 65% 2- and 5 y survival rates, respectively. CONCLUSION Survival after resection of RCC with isolated metastasis to the pancreas is favorable. However, a more detailed analysis considering outcomes without surgery for each primary tumor site is needed before the value of this aggressive surgical approach can be completely assessed in the general occurrence of pancreatic metastasis.

Abstract
INTRODUCTION We report a case of duodenum-preserving pancreatic head resection (DPPHR) for the treatment of pancreatic head metastasis from renal cell carcinoma (RCC). CASE REPORT The patient was a 59-year-old male with a medical history of RCC 18 years ago. Abdominal imaging studies revealed a hypervascular mass localized in the pancreatic head without distant metastasis or tumor invasion into the adjacent organs including the common bile duct and duodenum. Under the preoperative diagnosis of pancreatic metastasis from RCC, the tumor was completely resected by DPPHR. The pathological examination of the resected specimen confirmed the preoperative diagnosis. CONCLUSION As lymph node metastasis has been rarely reported in previous cases of pancreatic metastasis from RCC, DPPHR should be considered as a less invasive surgical option to provide a favorable postoperative quality of life (QOL).

Abstract
BACKGROUND Isolated pancreatic metastases (isPMs) of clear cell renal carcinoma are rare. Most of them are solitary; some are multiple. The reported rates and the clinical implications of multiple isPMs from clear cell renal cancer vary. Therefore, the available literature was analyzed to shed light on the clinical significance of these extremely rare metastatic lesions. METHODS A literature search brought to light 236 cases of isPMs (both solitary and multiple) from renal cell carcinoma. These were analyzed. RESULTS A total of 12% of the metastases were synchronous with the primary tumor, and 88% were metachronous, occurring 10.0 +/- 6.5 years (mean +/- SD) after nephrectomy. A predilection for a specific part of the pancreas was not identifiable. The localization of the renal cell cancer (left or right kidney) did not have any effect on the site of the metastases. Seventy-four (39%) of the metastases to the pancreas were multiple (3.2 +/- 1.5). Their epidemiology did not differ from that of solitary metastatic lesions. Actuarial 3- and 5-year survival rates after radical resection were 78% and 78%, respectively, for multiple versus 75% and 64% for solitary metastases. CONCLUSIONS The epidemiological data do not support a direct local lymphogenous or venous spread from the primary tumor to the pancreas. They rather suggest a systemic spread. Because of the positive outcome, radical removal of both solitary and multiple metastases should be attempted in eligible patients.

Abstract
Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is a proven modality for the diagnosis of primary pancreatic neoplasms. We describe our experience in diagnosing nonprimary pancreatic tumors by EUS-FNA. Cytology files were searched for all EUS-FNA of the pancreas for the period 2000-2002. All cases diagnosed as neoplasms were selected and those diagnosed as nonprimary pancreatic tumors were reviewed and analyzed. One hundred ninety-one of 468 cases were diagnosed as neoplasms. Eleven of these cases were diagnosed as nonprimary pancreatic tumors (2.4% of all diagnoses and 5.7% of all neoplasms). The diagnoses were supported by clinical history (n = 7), cytological findings (n = 11), cell block histology (n = 11), cell block immunohistochemistry (n = 6), and flow cytometry (n = 1). EUS-FNA is a safe and minimally invasive method for the diagnosis of nonprimary pancreatic neoplasms. Evaluation of clinical history, cytomorphology, and ancillary techniques, especially those applied to cell block material, are essential for accurate diagnoses.

Abstract
BACKGROUND The aim of the study is to analyze pancreatic metastases and their clinical, radiological, therapeutic and prognostic features. METHODS Three cases of pancreatic metastases observed and a world literature review of 333 cases were recorded. RESULTS Pancreatic metastases are due more frequently to renal cell carcinoma; they are usually metachronous and characterized by a long period of time between the resection of the primary tumor and their detection. The differential diagnosis with other pancreatic masses is difficult, but an accurate anamnesis, some peculiar findings of imaging techniques and percutaneous fine needle aspiration could allow preoperative diagnosis. Pancreatic resections are the treatment of choice allowing the better palliation and improving survival. 150/234 pancreatic metastases underwent pancreatic resections (resectability index = 64.1%); 88/132 patients are alive with a mean follow-up of 27.1 months; of the 44 dead patients the mean survival time was 21.3 months. Among pancreatic metastases the primary tumor with better prognosis is renal cell carcinoma. CONCLUSION Pancreatic metastases are rare; their preoperative diagnosis is difficult but useful and possible. Surgical resection is suggested because the patient still may have a prolonged survival.

Abstract
BACKGROUND Clear cell carcinomas of the pancreas are rare and more likely represent metastatic renal cell carcinoma (RCC). METHODS Twenty-one cases of metastatic RCC to the pancreas were retrieved from the files of the Endocrine Registry of the Armed Forces Institute of Pathology. Histologic features were reviewed, special stains and immunohistochemical studies were performed, and patient follow-up data were obtained. RESULTS The patients included 9 women and 12 men ages 47-76 years (mean, 64.4 years). Patients experienced weight loss, abdominal pain, or a mass lesion. The tumors occurred anywhere within the pancreas. The mean size of the tumors was 4.0 cm. Histologically, the tumors were comprised of clear cells with a rich vascular network. The RCC was diagnosed before (n = 17 patients; ages up to 32.7 years) or after (n = 4 patients; ages up to 13.2 years) the pancreatic metastases were discovered. Surgery was used in all patients. Adjuvant chemotherapy was used in 4 patients. From the date of the diagnosis of pancreatic metastasis, 13 patients were dead with disseminated disease (DD) (mean, 4.5 years), and 8 patients were without disease (mean, 9.0 years). From the date of the diagnosis of primary RCC, 13 patients were DD (mean, 12.7 years), and 8 patients were without disease (mean, 24.7 years). CONCLUSIONS Although histochemical and immunohistochemical studies may help in the distinction between patients with primary versus metastatic clear cell tumors of the pancreas, clinical confirmation should be obtained. Surgical resection of the pancreatic metastatic disease is suggested, because the patient may still have a prolonged survival.

Abstract
In nearly 25% of patients with primary renal-cell carcinoma, metastasis is not uncommon and usually does not give rise to difficulties in diagnosis. However, its presentation as a mass in the head of the pancreas following an elapse of several years after the initial diagnosis of renal carcinoma is not only uncommon but may be confused clinicoradiologically with a primary pancreatic adenocarcinoma. The case presented here illustrates such an example with an emphasis on the usefulness of fine-needle aspiration cytology (FNAC) in the diagnosis.

Abstract
CONCLUSION Pancreatic metastasis from renal cell carcinoma is extremely rare. The average time between nephrectomy and the diagnosis of metachronous metastases is reported to exceed 10 yr. Therefore, the initial diagnosis may be neglected in the cases of prolonged disease-free interval. When it does occur simultaneously or metachronously, aggressive surgical resection, when possible, seems to be the most effective treatment for this metastatic lesion. BACKGROUND An 81-yr-old female patient, who 8 yr previously had undergone right radical nephrectomy for renal cell carcinoma, presented with solitary pancreatic metastasis, which was successfully treated with a distal pancreatectomy. Only 66 cases of clinically diagnosed renal cell carcinoma metastatic to the pancreas are reported in the world literature and 49 of the patients (including ours) underwent a definitive surgical resection. Our case, treated by distal pancreatectomy, and a review of the relevant literature including all reported cases of renal cell carcinoma metastatic to the pancreas, are presented. RESULTS The patient was well without any evidence of recurrence at 22 mo after the operation.

Abstract
In this paper we report three cases of solitary pancreatic metastasis from renal cell carcinoma (RCC), treated surgically. Various features and the surgical approach of these metastases are discussed with references to the 33 previous published cases collected in the literature. Having eliminated widespread distant metastases, it is reasonable to restrict surgical resection of the pancreas to selected patients having a single synchronous or metachronous metastasis, or those having several unilateral metastatic foci. At any rate a careful long-term follow-up for patients with a past history of RCC is mandatory.
