However, several new expanded criteria were proposed, with the intent to increase the HCC patients eligible for LT, maintaining acceptable recurrence rates. The aim of the present study was to analyze a cohort of HCC patients, evaluating the evolutions in its management during the last 20 years and comparing the disease-free survivals among three different periods. HCC patients (n = 122) were transplanted and stratified in three periods: 1st (1988-1998, liberal selection), 2nd (1999-2003, use of MC) and 3rd (2004-2008, use of UCSF criteria). The three periods were analyzed and their survivals were compared. Statistical differences were reported at univariate analysis regarding to both dimensional (total tumor diameter) and biological (alpha feto-protein, microvascular invasion) HCC features. Comparing the 5-year survival rates, a progressive increase was observed in t...

A possible approach to this problem may be the use of donors positive for antibody against hepatitis B core antigen (anti-HBc). However, it is not clear whether recipients who receive anti-HBc-positive livers show worse survival. The aim of this study was to retrospectively analyze the patient and graft survivals of two groups of OLT recipients according to the anti-HBc status of their respective donors. We stratified 133 patients into group 1 (n = 120; anti-core-negative donors) versus group 2 (n = 13; anti-core-positive donors). Comparing the two groups by univariate analysis, there was no significant differences with regard to recipient, donor, or transplant characteristics. Group 2 showed worse 5-year patient (46.2% vs 72.0%; P = .006) and graft survivals (38.5% vs 68.4%; P = .003). After adjustment for several risk factors for post-OLT death and graft failure, there was no sign...

PVT is more commonly managed by endovenous thrombectomy, while SVT requires more complex technical expedients. Several surgical techniques have been proposed, such as extensive eversion thrombectomy, anastomosis to collateral veins, reno-portal anastomosis, cavo-portal hemi-transposition, portal arterialization and combined liver-intestinal transplantation. In order to achieve satisfactory outcomes, careful planning of the surgical strategy is mandatory. The excellent results that are obtained nowadays confirm that, even extended, splanchnic thrombosis is no longer an absolute contraindication for liver transplantation. Patients with advanced portal thrombosis may preferentially be referred to specialized centres, in which complex vascular approaches and even multivisceral transplantation are per...

We report the case of a 29-year-old Caucasian woman, who at ultrasound showed a cystic mass at the right kidney, with a vascular pattern at the level of the cystic wall. A CT-guided biopsy of the lesion was performed, revealing the presence of unspecified tumor cells. A total nephrectomy was then performed. Microscopically, a tumor resulting from the epithelial papillary cells was observed; several areas of lymphoplasmacytic infiltrates were seen at the junction between the normal kidney tissue and the tumor, and a renal medullary carcinoma was diagnosed. Six months later, the patient developed multiple pulmonary metastases and started chemotherapy with Carboplatin, Paclitaxel and Gemcitabine. The patient died after 27 months of follow-up.RMC is a tumor that usually occurs in young black men, at an average age of 25 years with...

Many procedures previously performed with an open access are now routinely carried out with the laparoscopic approach. Several advantages are associated with laparoscopic surgery compared to open procedures: reduced pain due to smaller incisions and hemorrhaging, shorter hospital length of stay, and a lower incidence of wound infections. Liver transplantation (LT) brought a radical change in life expectancy of patients with hepatic endstage disease. Today, LT represents the standard of care for more than fifty hepatic pathologies, with excellent results in terms of survival. Surely, with laparoscopy and LT being one of the most continuously evolving challenges in medicine, their recent combination has represented an astonishing scientific progress. The intent of the present paper is to underline the current role of diagnostic and therapeutic laparoscopy in patients waiting for LT, in the living donor LT and in LT recipients.

Here we sought to characterize the interactions between pancreatic cancer cells (PCCs) and PSCs that affect the inflammatory and immune response in pancreatic tumors. Conditioned media from mono- and cocultures of PSCs and PCCs were assayed for expression of cytokines and growth factors. IP-10/CXCL10 was the most highly induced chemokine in coculture of PSCs and PCCs. Its expression was induced in the PSCs by PCCs. IP-10 was elevated in human PDAC specimens, and positively correlated with high stroma content. Furthermore, gene expression of IP-10 and its receptor CXCR3 were significantly associated with the intratumoral presence of regulatory T cells (Tregs). In an independent cohort of 48 patients with resectable pancreatic ductal adenocarcinoma, high IP-10 expression levels correlated with decreased median o...

In the past decades, the inferior vena cava (IVC) reconstruction technique has undergone several evolutions, such as biopump, piggyback technique (PB), and laterolateral approach (LLPB). Several advantages are reported comparing the PB technique to biopump use. However, comparison between PB and LLPB has not been as well investigated. The aim of this study was to compare the results in terms of immediate graft function and intermediate graft survival among 3 subgroups characterized by distinct caval reconstruction techniques. Methods. We retrospectively analyzed a cohort of 200 consecutive adult patients who underwent liver transplantation from January 2001 to December 2009. The patients were stratified according to 3 caval reconstructive techniques: biopump (n ϭ 135), PB (n ϭ 32) and LLPB (n ϭ 33).
