Repeated pancreatic resection for pancreatic metastases from renal cell Carcinoma: A Spanish multicenter study (PANMEKID).

BACKGROUND AND OBJECTIVES: Recurrent isolated pancreatic metastasis from Renal Cell Carcinoma (RCC) after pancreatic resection is rare. The purpose of our study is to describe a series of cases of relapse of pancreatic metastasis from renal cancer in the pancreatic remnant and its surgical treatment with a repeated pancreatic resection, and to analyse the results of both overall and disease-free survival. METHODS: Multicenter retrospective study of patients undergoing pancreatic resection for RCC pancreatic metastases, from January 2010 to May 2020. Patients were grouped into two groups depending on whether they received a single pancreatic resection (SPS) or iterative pancreatic resection. Data on short and long-term outcome after pancreatic resection were collected. RESULTS: The study included 131 pancreatic resections performed in 116 patients. Thus, iterative pancreatic surgery (IPS) was performed in 15 patients. The mean length of time between the first pancreatic surgery and the second was 48.9 months (95 % CI: 22.2-56.9). There were no differences in the rate of postoperative complications. The DFS rates at 1, 3 and 5 years were 86 %, 78 % and 78 % vs 75 %, 50 % and 37 % in the IPS and SPS group respectively (p = 0.179). OS rates at 1, 3, 5 and 7 years were 100 %, 100 %, 100 % and 75 % in the IPS group vs 95 %, 85 %, 80 % and 68 % in the SPS group (p = 0.895). CONCLUSION: Repeated pancreatic resection in case of relapse of pancreatic metastasis of RCC in the pancreatic remnant is justified, since it achieves OS results similar to those obtained after the first resection.

Pancreatic metastases from renal cell carcinoma. Postoperative outcome after surgical treatment in a Spanish multicenter study (PANMEKID).

BACKGROUND: Renal Cell Carcinoma (RCC) occasionally spreads to the pancreas. The purpose of our study is to evaluate the short and long-term results of a multicenter series in order to determine the effect of surgical treatment on the prognosis of these patients. METHODS: Multicenter retrospective study of patients undergoing surgery for RCC pancreatic metastases, from January 2010 to May 2020. Variables related to the primary tumor, demographics, clinical characteristics of metastasis, location in the pancreas, type of pancreatic resection performed and data on short and long-term evolution after pancreatic resection were collected. RESULTS: The study included 116 patients. The mean time between nephrectomy and pancreatic metastases' resection was 87.35 months (ICR: 1.51-332.55). Distal pancreatectomy was the most performed technique employed (50 %). Postoperative morbidity was observed in 60.9 % of cases (Clavien-Dindo greater than IIIa in 14 %). The median follow-up time was 43 months (13-78). Overall survival (OS) rates at 1, 3, and 5 years were 96 %, 88 %, and 83 %, respectively. The disease-free survival (DFS) rate at 1, 3, and 5 years was 73 %, 49 %, and 35 %, respectively. Significant prognostic factors of relapse were a disease free interval of less than 10 years (2.05 [1.13-3.72], p 0.02) and a history of previous extrapancreatic metastasis (2.44 [1.22-4.86], p 0.01). CONCLUSIONS: Pancreatic resection if metastatic RCC is found in the pancreas is warranted to achieve higher overall survival and disease-free survival, even if extrapancreatic metastases were previously removed. The existence of intrapancreatic multifocal compromise does not always warrant the performance of a total pancreatectomy in order to improve survival.

Cholangiocarcinoma, 10-Year Survival After Liver Transplantation: A Case Report.

Cholangiocarcinoma is the second most common neoplasm in the liver, with a very poor, short-term prognosis. Today, surgery associated with or without an adjuvant is the only curative treatment. Liver transplantation (LT) is the best treatment for hepatocellular carcinoma tumor. In recent years, treatment of hilar cholangiocarcinoma by LT associated with neoadjuvant therapy has been studied under a criterion. But could it be possible to apply LT like the curative treatment of intrahepatic cholangiocarcinoma (iCC)? Initially the answer is no, but there are different studies about incidental LT in patients with iCC that demonstrate survival over 40% to 50%. In our center, we conducted a review of 468 transplants completed between 2002 and 2018, and we identified 1 case of incidental LT in a patient with iCC with an overall survival of 10 years. Because there is currently an increase in donors owing to the expansion of the criteria, a study to consider extending the criteria of LT to include iCC would be beneficial.

Impact of Everolimus-based Immunosuppression on Renal Function in Liver Transplant Recipients.

BACKGROUND: Calcineurin inhibitors have been implicated in acute and chronic kidney disease after liver transplant (LT). Everolimus (EVR) is a mammalian target of rapamycin inhibitor efficacious in preventing acute cellular rejection while preserving renal function among LT recipients. We evaluated the benefits on renal function of EVR immunosuppression in LT recipients. METHODS: We performed a retrospective and observational study in 477 LT recipients in Virgen de las Nieves Hospital from 2002 to 2019 on the use of EVR with tacrolimus minimization or withdrawal in LT recipients with renal dysfunction. The study included 100 patients starting EVR (20.96%); in 66 (66%) the indication was renal dysfunction. The change in renal function was assessed by estimated glomerular filtration rate. Statistical analyses were performed using SPSS 17.0 software (IBM, Munich, Germany). RESULTS: Fifty 8 patients received mycophenolate mofetil (87.8%), and tacrolimus therapy was stopped in 27 patients (40.9%). Induction therapy with basiliximab was administered in 41 patients (62.12%). There was significant difference between estimated glomerular filtration rate at the time of starting EVR and the first month at last follow-up (49.42 mL/min/1.73 m2 vs 75.27 mL/min/1.73 m2; P < .001) and at end of follow-up (24 months) (49.42 mL/min/1.73 m2 vs 64.32 mL/min/1.73 m2; P = .001). The rate of incidence of adverse events was 48.48% (32/66). Seven patients died during follow-up (10.6%), but there were no EVR-related deaths. Eleven patients (16.6%) developed biopsy-proven acute rejection. CONCLUSION: This study showed that EVR is associated with a beneficial effect on glomerular filtration rate in both the short and long term in LT recipients.

Eight Years of Extracorporeal Membrane Oxygenation in Liver Transplantation: Our Experience.

Liver grafts from donors after cardiac death (DCD) involve a risk of failure owing to warm ischemia, among other factors. To minimize this important issue, new systems like normothermic regional perfusion have arisen. We report an observational and unicentric study focused on the results of liver transplantation after DCD, performing normothermic regional perfusion using extracorporeal membrane oxygenation. In the period between 2011 and 2018, 33 recipients underwent the procedure, 9 from Maastricht II DCD donor liver transplantation (LT) and 24 from Maastricht III DCD donors. The median recipient survival rose to 67 ± 9 months and 41 ± 7 months, respectively. Only 1 patient suffered from ischemic cholangiopathy needing retransplantation. Therefore, according to our experience, liver grafts from DCD using extracorporeal membrane oxygenation are suitable for LT.

Liver metastasis from colorectal cancer 12 years after liver transplantation.

Liver transplantation is an effective treatment for many liver diseases, with a 5-year survival of about 70 %. However, development of de novo malignancies in these immunocompromised patients is becoming a frequent complication medium term. The annual risk of developing a malignant tumor after a solid organ transplant is 2% . We report the case of a liver transplant patient who developed colorectal neoplasia at 12 years after transplantation , and then a metachronous metastases in the liver transplanted.

Tumores de la estroma gastrointestinal y neurofibromatosis tipo 1 / Gastrointestinal stromal tumors and neurofibromatosis

La asociación entre tumores de la estroma gastrointestinal (GIST) y neurofibromatosis es un hecho poco frecuente que normalmente produce sintomatología que requiere tratamiento quirúrgico. En los últimos 12 años sólo aparecen recogidos en PubMed 23 casos de pacientes con esta asociación. Presentamos a continuación dos casos clínicos, uno de naturaleza benigna y otro maligna, que se iniciaron con cuadros de hemorragia digestiva baja de repetición y que precisaron tratamiento quirúrgico. Asimismo, realizamos una revisión de la bibliografía sobre estos GIST y su asociación con la neurofibromatosis tipo 1 (AU)
