“…The median MINORS score of 10/16 indicated a degree of methodological flaw in these papers, and is consistent with MINORS scores found in a recent systematic review of hepatic metastasectomy [24].…”

“…However, this strategy has yet to be validated in the context of a prospective randomised controlled trial, and hence clinicians are guided by accumulated experience in the form of case series from high-volume centres [24][25][26]. Given the rarity of pancreatic metastases, it is understandably difficult to accrue sufficient data to justify any particular management approach.…”

“…However, it should be pointed out that there are no randomised studies of metastasectomy in any setting [24][25][26]35]. A further limitation is the short duration of follow-up-11 of 18 studies reported 5-year survival data, but new data are emerging to suggest that, in the case of liver metastases at least, 10-year survival may a more pertinent measure, as cancer-related death only appears to plateau after 10 years [45,46].…”

Aim: Tumours rarely metastasise to the pancreas. While surgical resection of such metastases is believed to confer a survival benefit, there is limited data to support such management. We present a systematic review of case series of pancreatic metastasectomy and analysis of survival outcomes.Methods: A literature search was performed using the PubMed and Cochrane databases and the reference lists of relevant articles, searching for sizeable case series of pancreatic metastasectomy with curative intent. Data extracted included basic demographics, histological primary tumour, presentation, operative management, complications and survival, while the MINORS index was used to assess study quality.Results: 18 studies were found which met our inclusion criteria, involving 399 patients. Renal cell carcinoma (RCC) was the commonest malignancy metastasising to the pancreas, responsible for 62.6% of cases, followed by sarcoma (7.2%) and colorectal carcinoma (6.2%). While survival data was not uniformly reported, the median survival post-metastasectomy was 50.2 months, with a oneyear survival of 86.81% and five-year survival of 50.02%. Median survival for RCC was 71.7 months with 70.4% five-year survival. Median survival was similar in patients with synchronous and metachronous pancreatic metastases, but patients with additional extrapancreatic metastases had a significantly shorter survival than patients with isolated pancreatic metastases (26 versus 45 months). Study quality was poor, with a median MINORS score of 10/16. Conclusions:Within the limitations of a review of non-randomised case series, it would appear that pancreatic metastasectomy confers a survival benefit in selected patients. Better evidence is required, but may prove difficult to acquire. Key words:pancreatic metastasis, metastasectomy, pancreatectomy, metastatic renal cell cancer, 3 Introduction:

“…The incidence of malignant melanoma has been demonstrated to be increasing worldwide (2). Choroidal melanoma is fatal in ~50% of patients due to its latency and metastatic potential, and the principal target organ for metastasis is the liver (3,4). Early detection and therapy is important for improving the prognosis of patients (5); however, the underlying molecular mechanisms of disease development remain to be elucidated.…”

Abstract. The aim of the present study was to explore the effects of gambogenic acid (GNA) on the malignant behaviors of choroidal melanoma cells, including cell viability, cell cycle, migration and invasion, and to elucidate the underlying regulatory mechanism. The human choroidal melanoma cell line OCM-1 was treated with different concentrations of GNA and cell viability, colony formation ability, cell cycle, migration and invasion were analyzed. Additionally, cells were incubated with or without LY294002, a specific inhibitor of the phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway, for 24 h. Levels of cell cycle-associated proteins (cyclin D1, cyclin E, cyclin-dependent kinase 2 and P21), epithelial-mesenchymal transition (EMT)-associated molecules (epithelial-cadherin, α-smooth muscle actin and vimentin) and phosphorylated (p)-AKT/AKT were determined using reverse transcription-quantitative polymerase chain reaction and western blot analysis. The results demonstrated that GNA significantly inhibited cell viability and induced cell cycle arrest at the G0/G1 phase in a dose-dependent manner (P<0.01). Furthermore, GNA administration significantly suppressed cell migration and invasion in a dose-dependent manner (P<0.01). Treatment with GNA or LY294002 induced a marked decrease in the expression of p-AKT/AKT, a significant downregulation in cell cycle-associated molecules (P<0.01), and a significant decrease in cell viability (P<0.01). Co-treatment with LY294002 and GNA had an additive effect on the growth of OCM-1 cells. In conclusion, the results of the present study suggest that treatment with GNA may inhibit cell viability and induce G0/G1 arrest. Furthermore, GNA may also inhibit cell metastasis via regulating EMT-associated molecules. The PI3K/Akt signaling pathway may be a key mechanism involved in the progression of choroidal melanoma, and GNA may serve as a potential therapeutic reagent for the treatment of this disease.

“…Data from this review indicates that the presence of multiple lesions involving one viscera is not a contraindication to surgical therapy if R0 resection is achievable (26). However, in the majority of patients, hepatectomy is impossible due to the extent or location of metastatic melanoma (4).…”

Complete resection of isolated hepatic metastatic uveal melanoma with a notably long disease-free period: A case report and review of the literature

et al. 2015

Abstract. Although uveal melanoma frequently metastasizes to the liver, cases with a large solitary lesion with spontaneous intratumoral hemorrhage and necrosis are rarely encountered. Here, we report a case of metastatic hepatic melanoma that occurred in a 45-year-old Chinese male. The patient complained of the feeling of a full stomach for a month. Ten years earlier, the patient had undergone left ocular enucleation and artificial eye implantation at a different hospital. Postoperative pathology revealed choroidal melanoma without intrascleral or vascular involvement. Abdominal magnetic resonance imaging and computed tomography scan revealed a solitary lesion measuring 12 cm in diameter. A whole-body F-18-fluoro-2-deoxyglucose (FDG) positron emission tomography/computed tomography scan demonstrated a large solitary nodule with increased FDG uptake. Computed tomography angiography revealed that the huge mass had partially ruptured and was bleeding spontaneously. For diagnostic and therapeutic purposes, right hepatectomy was performed and histological examination revealed that the tumor was metastatic melanoma.

Systematic review and meta-analysis of liver resection for metastatic melanoma

Abstract: Radical resection of liver metastases from melanoma appears to improve overall survival compared with non-operative management or incomplete resection, but this observation requires future confirmation as selection bias may have confounded the results.
