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.

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
BACKGROUND The therapeutic approach of metastatic renal cell carcinoma (RCC) represents a real challenge for clinicians, because of the variable clinical course; the recent availability of numerous targeted therapies that have significantly improved overall oncological results, but still with a low percentage of complete responses; and the increasing role of metastasectomy (MSX) as an effective strategy to achieve a durable cure, or at least defer initiation of systemic therapies, in selected patients and in the context of multimodality treatment strategies.
CASE SUMMARY We report here the case of a 40-year-old man who was referred to our unit in November 2004 with lung and mediastinal lymph nodes metastases identified during periodic surveillance 6 years after a radical nephrectomy for RCC; he underwent MSX of multiple lung nodules and mediastinal lymphadenectomy, with subsequent systemic therapy with Fluorouracil, Interferon-alpha and Interleukin 2. The subsequent clinical course was characterized by multiple sequential abdominal and thoracic recurrences, successfully treated with multiple systemic treatments, repeated local treatments, including two pancreatic resections, conservative resection and ablation of multiple bilobar liver metastases, resection and stereotactic body radiotherapy of multiple lung metastases. He is alive without evidence of recurrence 20 years after initial nephrectomy and sequential treatment of recurrences in multiple sites, including resection of more than 38 metastases, and 5 years after his last MSX.
CONCLUSION This case highlights that effective multimodality therapeutic strategies, including multiple systemic treatments and iterative aggressive surgical resection, can be safely performed with long-term survival in selected patients with multiple metachronous sequential metastases from RCC.

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.

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 After the screening process of articles, 21 were selected for the systematic review, which included 354 patients, whose disease-free interval (DFI) was 105.11 (0-361.56) months. Of these patients, 34.6% had additional metastases elsewhere at the time of the surgery, and 48.6% were symptomatic. Postoperative morbidity was 40.2%, The 5-year overall survival (OS) rate was 53.9% (26-75). CONCLUSION Pancreatic surgery for the resection of RCC metastasis(es) is considered safe and shows low morbidity and mortality rates among selected patients in medical institutions where this type of procedure is commonly performed.

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
Isolated pancreatic metastases (isPM) are a rare metastasizing pattern in the natural history of renal cell cancer. Their clinical hallmark is that they are confined to a single organ, the pancreas, while all other organs are unaffected for a long time. Almost all workers in the field suggested that mechanical tumor cell propagation to the pancreas may be the mechanism underlying this metastasizing pattern. In 2006 our group, by contrast, proposed an alternative mechanism, i.e. a special affinity of the tumor cells for the pancreas. In the present study an attempt was made to shed more light on the settlement of isPM by reviewing recent literature data. 666 observations of isPM reported in the literature were reviewed. The analyses showed that local lymphatic spread does not play a major role because the lymphatic system is, in general, rarely involved in isPM. This also applies to a local venous spread, because the site of pancreatic metastases is independent of the side affected by the primary renal cancer. But the results are compatible with a systemic metastatic pathway. That metastases in other organs, which would be expected given a systemic spread, are absent can plausibly be explained by a seed and soil mechanism: only the pancreas offers the tumor cell emboli an environment which is conducive to the growth of clinically manifest metastases, while settlement of metastatic tumor cells is prevented in all other organs.

Abstract
Pancreatic metastases from other primary malignancies are a rare entity. By far, the most common primary cancer site resulting in an isolated pancreatic metastasis is the kidney, followed by colorectal cancer, melanoma, breast cancer, lung carcinoma and sarcoma. Only few data on the surgical outcome of pancreatic resections performed for metastases from other primary tumor have been published, and there are no guidelines to address the surgical treatment for these patients. In this study, we performed a review of the published literature, focusing on the early and long-term results of surgery for the most frequent primary tumors metastasizing to the pancreas. Results for the Literature’s analysis show that in last years an increasing number of surgical resections have been performed in selected patients with limited pancreatic disease. Pancreatic resection for metastatic disease can be performed with acceptable mortality and morbidity rates. The usefulness of pancreatic resection is mainly linked to the biology of the primary tumor metastasizing to the pancreas. The benefit of metastasectomy in terms of patient survival has been observed for metastases from renal cell cancer, while for other primary tumors, such as lung and breast cancers, the role of surgery is mainly palliative.

Abstract
We present a case report of a 75-years-old woman affected by renal clear cell carcinoma with a synchronous pancreatic metastasis and a metachronous lung metastasis. This case has two peculiarities. First the pancreatic metastasis was treated just with medical therapy, that is, Sunitinib, instead of the surgical therapy that is mostly considered. Secondly, the pancreatic lesion showed different characteristics on the computed tomography scan compared to the usual pancreatic metastases from renal clear cell carcinoma. The pancreatic metastasis totally regressed after medical treatment and nowadays, four years after the diagnosis, the patient is disease-free.

Abstract
AIM The multi-tyrosine kinase inhibitor pazopanib prolongs progression-free survival (PFS) versus placebo in treatment-naive and cytokine-refractory metastatic clear-cell renal cell carcinoma (ccRCC). Outcomes and safety data with pazopanib after targeted therapy (TT) are limited. METHODS We retrospectively evaluated records of consecutive patients with metastatic ccRCC who had progressive disease (PD) after TT and received pazopanib from November 2009 through November 2011. Tumour response was assessed by a blinded radiologist using Response Evaluation Criteria In Solid Tumours (RECIST). PFS and overall survival (OS) were estimated by Kaplan-Meier methods. RESULTS Ninety-three patients were identified. Median number of prior TTs was 2 (range, 1-5). There were 68 events (PD or death). Among 85 evaluable patients, 13 (15%) had a partial response. Median PFS was 6.5 months (95% CI: 4.5-9.7); median OS was 18.1 months (95% CI: 10.26-NA). Common adverse events (AEs) included fatigue (44%), elevated transaminases (35%), diarrhoea (30%), hypothyroidism (18%), nausea/vomiting (17%), anorexia (14%) and hypertension exacerbation (14%); 91% of AEs were grade 1/2. Eleven patients (12%) discontinued therapy due to AEs. There were no treatment-related deaths. CONCLUDING STATEMENT Pazopanib demonstrated efficacy in patients with metastatic ccRCC after PD with other TTs. Toxicity overall was mild/moderate and manageable.

Abstract
Renal cell carcinoma is known to have blood-borne metastasis. This is usually to the bone, lungs and brain. Other unusual metastatic presentations such as skin and bowel metastasis have also been described. In most cases, the metastasis occurs as a late manifestation in a patient with known primary renal cell carcinoma. A rare synchronous presentation of skin and duodenal metastasis in an otherwise asymptomatic patient is reported here. This patient presented with a skin lesion that, on excision, brought up the diagnosis of metastatic renal cell carcinoma. While the patient was waiting for surgery, she also developed melena that, on gastroscopy, confirmed a duodenal metastasis. This case highlights the importance of early recognition of otherwise unrelated lesions as presentations for an advanced renal malignancy.
