Abstract
Colorectal cancer (CRC) is the third most prevalent type of cancer, and liver metastasis is the most common site of metastatic development. In the tumor microenvironment (TME), various innate immune cells are known to influence cancer progression and metastasis occurrence. CD274 (PD-L1) and CD206 (MRC1) are proteins that have been associated with poor prognosis and disease progression. We conducted a study on tumoral and non-tumoral biopsies from 47 patients with CRC liver metastasis, using flow cytometry to phenotypically characterize innate immune cells. Our findings showed an increase in the expression of CD274 on classical, intermediate, and non-classical monocytes when comparing tumor with non-tumor samples. Furthermore, tumor samples with a desmoplastic growth pattern exhibited a significantly decreased percentage of CD274- and CD206-positive cells in all monocyte populations compared to non-desmoplastic samples. We found a correlation between a lower expression of CD206 or CD274 on classical, intermediate, and non-classical monocytes and increased disease-free survival, which points to a better prognosis for these patients. In conclusion, our study has identified potential new targets and biomarkers that could be incorporated into a personalized medicine approach to enhance the outcome for colorectal cancer patients.

Abstract
INTRODUCTION The benefits of the multimodal Enhanced Recovery After Surgery® (ERAS) program have been described all over the world. The adoption of several perioperative strategies translates into an improvement in the quality of the healthcare provided. The aim of this study was to report the results of the implementation of the ERAS® program for colorectal surgery in a tertiary hospital. MATERIAL AND METHODS In this single-center observational study, 534 patients who underwent colorectal surgery between December 2018 and May 2021 were included. Two groups were considered: before and after the implementation of the ERAS® program. The primary outcome measure was 30-day morbidity. The length of hospital stay, readmission rate, reintervention and mortality among the two groups were also evaluated. RESULTS The pre-ERAS group included 102 patients and the ERAS group included 432 patients. There was a statistically significant reduction in morbidity at 30 days (37.3% vs 26.5%, p < 0.05), length of stay (7 days vs 5 days, p < 0.001) and readmission rate (12.9% vs 6%, p < 0.05) after the implementation of the ERAS program. CONCLUSION The ERAS® protocol for colorectal surgery was successfully and safely implemented in our hospital, contributing to an improvement in perioperative care provided to patients.

Abstract
Pancreatic cancer is one of the most fatal malignancies, as approximately 80% of patients are at advanced stages by the time of diagnosis. The main reason for the poor overall survival is late diagnosis that is partially due to the lack of tools for early-stage detection. In addition, there are several challenges in evaluating response to treatment and predicting prognosis. In this article, we do a review of the most common pancreatic cancer biomarkers with emphasis in new and promising approaches. Liquid biopsies seem to have important clinical applications in early detection, screening, prognosis, and longitudinal monitoring of on-treatment patients. Together with biomarkers in imaging, can represent valuable alternative non-invasive tools in order to achieve a more effective management of pancreatic cancer patients.

Abstract
Our aim was to study the association between preoperative biliary drainage (PBD) and morbidity following cephalic pancreaticoduodenectomy (CPD) for pancreatic ductal adenocarcinoma (PDAC) and its prognostic impact, which is still controversial in the literature. A retrospective study was conducted, which included 128 patients who underwent CPD for PDAC, divided into two groups: those who underwent PBD (group 1) and those who did not undergo this procedure (group 2). Group 1 was subdivided according to the drainage route: endoscopic retrograde cholangiopancreatography (ERCP), group 1.1, and percutaneous transhepatic cholangiography (PTC), group 1.2. 34.4% of patients underwent PBD, and 47.7% developed PBD-related complications, with 37% in group 1.1 and 64.7% in group 1.2 (p = 0.074). There was a significant difference between group 1 and 2 regarding bacterial colonization of the bile (45.5% vs. 3.6%, p < 0.001), but no difference was found in the colonization by multidrug-resistant bacteria, the development of Clavien–Dindo ≥ III complications, clinically relevant pancreatic fistula and delayed gastric emptying (DGE), intra-abdominal abscess, hemorrhage, superficial surgical site infection (SSI), and readmission. Between groups 1.1 and 1.2, there was a significant difference in clinically relevant DGE (44.4% vs. 5.9%, p = 0.014) and Clavien–Dindo ≥ III complications (59.3% vs. 88.2%, p = 0.040). There were no significant differences in median overall survival and disease-free survival (DFS) between groups 1 and 2. Groups 1.1 and 1.2 had a significant difference in DFS (10 vs. 5 months, p = 0.017). In this group of patients, PBD was associated with increased bacterial colonization of the bile, without a significant increase in postoperative complications or influence in survival. ERCP seems to contribute to the development of clinically significant DGE. Patients undergoing PTC appear to have an early recurrence.

Abstract
Colorectal cancer (CRC) is one of the most common cancers worldwide, with liver metastasis being its main cause of death. This study harvested fresh biological material from non-tumor and tumor tissue from 47 patients with CRC liver metastasis after surgery, followed by mechanical cellular extraction and stain-lyse-wash direct immunofluorescence technique. Here, 60 different T-cell populations were characterized by flow cytometry. Tumor samples were also subdivided according to their growth pattern into desmoplastic and non-desmoplastic. When we compared tumor versus non-tumor samples, we observed a significantly lower percentage of T-lymphocyte infiltration in the tumor in which the CD4+ T-cell density increased compared to the CD8+ T cells. T regulatory cells also increased within the tumor, even with an activated phenotype (HLA-DR+). A higher percentage of IL-17-producing cells was present in tumor samples and correlated with the metastasis size. In contrast, we also observed a significant increase in CD8+ follicular-like T cells (CD185+), suggesting a cytotoxic response to cancer cells. Additionally, most infiltrated T cells exhibit an intermediate activation phenotype (CD25+). In conclusion, our results revealed potential new targets and prognostic biomarkers that could take part in an algorithm for personalized medicine approaches improving CRC patients' outcomes.

Abstract
Acute pancreatitis (AP) is an inflammatory process of the pancreas with variable involvement of the pancreatic and peripancreatic tissues and remote organ systems. The main goal of this study was to evaluate the inflammatory biomarkers, oxidative stress (OS), and plasma metabolome of patients with different degrees of biliary AP severity to improve its prognosis. Twenty-nine patients with biliary AP and 11 healthy controls were enrolled in this study. We analyzed several inflammatory biomarkers, multifactorial scores, reactive oxygen species (ROS), antioxidants defenses, and the plasma metabolome of biliary AP and healthy controls. Hepcidin (1.00), CRP (0.94), and SIRI (0.87) were the most accurate serological biomarkers of AP severity. OS played a pivotal role in the initial phase of AP, with significant changes in ROS and antioxidant defenses relating to AP severity. Phenylalanine (p < 0.05), threonine (p < 0.05), and lipids (p < 0.01) showed significant changes in AP severity. The role of hepcidin and SIRI were confirmed as new prognostic biomarkers of biliary AP. OS appears to have a role in the onset and progression of the AP process. Overall, this study identified several metabolites that may predict the onset and progression of biliary AP severity, constituting the first metabonomic study in the field of biliary AP.

Abstract
Necrotising fasciitis (NF) is a severe infection of the subcutaneous tissue and fascia that can rapidly lead to sepsis and shock with high mortality rates. Its initial signs are often non-specific making it difficult for an early diagnosis to be reached. Nevertheless it is of the utmost importance to begin proper treatment including wide surgical debridement as soon as possible in order to avoid death. We present the case of a patient with NF of the thoracic wall which is a rare location for this disease but often associated with worse prognosis. Even though he progressed to septic shock within less than 24 hours of its presentation, due to early surgical management, aggressive resuscitation and intensive care support, he reached a favourable outcome. After three surgical revisions and 2 weeks in an intensive care unit, the patient was discharged from hospital 35 days after admission.

Abstract
AIMS Cholangiocarcinoma (CC) is a rare tumour arising from the biliary tract epithelium. The aim of this study was to perform a genomic characterisation of CC tumours and to implement a model to differentiate extrahepatic (ECC) and intrahepatic (ICC) cholangiocarcinoma. METHODS DNA extracted from tumour samples of 23 patients with CC, namely 10 patients with ECC and 13 patients with ICC, was analysed by array comparative genomic hybridisation. A support vector machine algorithm for classification was applied to the genomic data to distinguish between ICC and ECC. A survival analysis comparing both groups of patients was also performed. RESULTS With these whole genome results, we observed several common alterations between tumour samples of the same CC anatomical type, namely gain of Xp and loss of 3p, 11q11, 14q, 16q, Yp and Yq in ICC tumours, and gain of 16p25.3 and loss of 3q26.1, 6p25.3-22.3, 12p13.31, 17p, 18q and Yp in ECC tumours. Gain of 2q37.3 was observed in the samples of both tumour subtypes, ICC and ECC. The developed genomic model comprised four chromosomal regions that seem to enable the distinction between ICC and ECC, with an accuracy of 71.43% (95% CI 43% to 100%). Survival analysis revealed that in our cohort, patients with ECC survived on average 8 months less than patients with ICC. CONCLUSIONS This genomic characterisation and the introduction of genomic models to clinical practice could be important for patient management and for the development of targeted therapies. The power of this genomic model should be evaluated in other CC populations.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide and the third cause of cancer-related death. Current clinical/pathological criteria contribute to risk stratification, but are far from the desired on individualized medicine. Recently, HCC classifications have been published based on immunohistochemical and morphological features. METHODS A retrospective review of patients submitted to surgical treatment-partial hepatectomy (PH) or liver transplantation (LT), with pathological diagnosis of HCC, in a 9-year period (2007-2015) was performed. RESULTS Applying the classification of Srivastava et al. (#1), based on the expression of CD31, p53, AFP and CD44, tumour size and presence of vascular invasion, HCC were categorized as low- and high-risk HCC. With the classification of Tsujikawa et al. (#2), HCC were classified into biliary/stem cell marker positive, Wnt signalling positive and the "all negative" HCC, according to the expression of CK19, SALL4, β-catenin glutamine synthetase, EpCAM and p53. There were sixty-six patients (53 males; 13 females), with median age of 64.5 ± 9.46 years (range 38-86), with solitary HCC, comprehending 37 PH (56.1%) and 29 LT (43.9%). The mean overall survival (OS) was 75.4 ± 6.9 months. Biliary/stem cell type of HCC was a predictive factor of worse OS on the overall population (24.4 versus 78.3 months, p = 0.032) and in PH cohort (11.5 versus 64.01 months, p = 0.016), on uni- and multivariate analyses. CONCLUSION These results support the relevance of a risk stratification classification of HCC. Classification #2 seems adequate to our reality demonstrating OS impact, allowing its application in future biopsies, prompting individualized medicine.

Abstract
Purpose Hepatectomy (Hp) is an alternative approach for the treatment of gastric carcinoma liver metastases (GCLM). However, prognostic factors that may assist patient selection are still controversial. Several pathologic features, such as the growth pattern (GP), associated with prognosis in colorectal cancer liver metastases, were never investigated in GCLM. Our principal aim was to assess if the GP has prognostic impact on GCLM. Patients and Methods Review of the clinical and pathological characteristics of 19 consecutive patients submitted to surgical resection of GCLM with curative intent at our department. Major potential prognostic factors considered were patients’ gender, age, timing and extent of Hp, postoperative course, as well as histopathological characteristics of primary and secondary tumors. Results Major morbidity occurred in four patients, mortality in one. Median and 5-year overall survival were 17 months and 26.7%, respectively. Ten patients developed recurrent disease and two patients survived more than 10 years. Factors independently associated with overall survival were the absence of major morbidity, distal location of the primary tumor, and desmoplastic GP (p<0.05). Conclusion The selection of patients is crucial for the improvement of survival rates of GCLM. Consequently, we demonstrate for the first time that the desmoplastic GP of GCLM is associated with improved outcomes, prompting further research on tumor–host interactions.

Abstract
Acute pancreatitis (AP) is an inflammatory disorder of the pancreas that, when classified as severe, is associated with high morbidity and mortality. Promptly identifying the severity of AP is of extreme importance for improving clinical outcomes. The aim of this study was to compare the prognostic value of serological biomarkers, ratios, and multifactorial scores in patients with acute biliary pancreatitis and to identify the best predictors. In this observational and prospective study, the biomarkers, ratios and multifactorial scores were evaluated on admission and at 48 h of the symptom onset. On admission, regarding the AP severity, the white blood count (WBC) and neutrophil-lymphocyte ratio (NLR), and regarding the mortality, the WBC and the modified Marshall score (MMS) showed the best predictive values. At 48 h, regarding the AP severity, the hepcidin, NLR, systemic inflammatory response index (SIRI) and MMS and regarding the mortality, the NLR, hepcidin and the bedside index for severity in AP (BISAP) score, showed the best predictive values. The present study enabled the identification, for the first time, of SIRI as a new prognostic tool for AP severity, and validated hepcidin and the NLR as better prognostic markers than C-reactive protein (CRP) at 48 h of symptom onset.

Abstract
Most patients with familial adenomatous polyposis (FAP) will develop duodenal polyps and 5% progress to cancer. Those with Spigelman stage IV have a 36% risk of cancer at 10 years. Endoscopic surveillance is necessary with local ablation for early disease. Unresectable duodenal disease and severe dysplasia are an indication for prophylactic radical surgery by pancreaticoduodenectomy or pancreas-sparing duodenectomy. Some preliminary results have shown better outcomes with duodenectomy. A 45-year-old female with FAP had restorative proctocolectomy at 24 years, desmoid of the mesentery with regression after sulindac, two pregnancies, and at the age of 37 years had duodenal polyposis stage III carpeting the periampullary region. Endoscopic papillectomy and extensive piecemeal mucosectomy was performed but was unsuccessful due to recurrence. After 7 years of regular endoscopic surveillance, focal high-grade dysplasia was diagnosed at the last evaluation. Some diminutive polyps were seen in the small-bowel capsule endoscopy. MRCP showed a normal biliary and pancreatic duct without visualization of the Santorini duct. A pancreas and pylorus-preserving duodenectomy was performed with 3 main steps: (1) duodenectomy with preservation of the pancreas and the pylorus; (2) reconstruction with an advanced jejunal limb and duodenojejunostomy; (3) reimplantation of the biliary and pancreatic duct in the jejunal loop. The patient was discharged on the 11th postoperative day without complications. In conclusion, pancreas- and pylorus-preserving duodenectomy is a promising alternative to pancreaticoduodenectomy for advanced duodenal polyposis that allows complete endoscopic surveillance.

Abstract
Serous pancreatic cystadenomas are benign tumours and most cases are detected incidentally. Complications are unusual. A patient with a history of a large pancreatic serous cystadenoma (SCA) presented to the emergency department with abdominal pain and haemodynamic shock. After haemodynamic stabilisation, an urgent abdominal CT scan revealed a large hemoperitoneum but the origin of the bleeding was not found. The patient was submitted to an angiography that revealed a bleeding hypervascular pancreatic mass and an embolisation was done successfully. After 3 weeks, the patient underwent a laparotomic left pancreatectomy with en bloc splenectomy. The anatomopathological results were consistent with a microcystic SCA of the pancreas. Despite the high vascularity of pancreatic SCA, haemorrhage is a very rare but life-threatening complication.

BACKGROUND Living donor liver transplantation (LDLT) is an accepted option for patients with end-stage liver disease. However, it potentially carries the risk of donor morbi-mortality, as well as long-term functional impairment. Cholecystectomy is performed routinely in the donor intervention, but the long-term effect on gastrointestinal (GI)-related quality of life (QoL) has never been explored previously. This study evaluated living donors' overall, abdominal wall-related, activity-level, and GI-related QoL. MATERIALS AND METHODS In total, 21 living liver donors (LLD) (57% women, mean age 45 ± 9 years) were compared to a control group (29 patients) undergoing cholecystectomy for gallbladder polyps (45% women, mean age of 46 ± 7 years). LLD and controls (Ctl) were divided into 2 age groups: LLD-Y and Ctl-Y (25-45 years); and LLD-O and Ctl-O (46-65 years). Generic SF-36, Gastrointestinal Quality of Life Index, EuraHS for abdominal wall status assessment, and International Physical Activity Questionnaire were performed. Standard age-adjusted Portuguese population SF-36 scores were used. RESULTS Global QoL results were better than Portuguese population scores and not inferior when compared to controls, scoring higher in the LLD-Y group in domains as vitality and mental health (P < .05). The abdominal wall impact was minimal among LLD. The activity level was significantly higher in LLD-Y than in Ctl-Y. Overall GI-related QoL was very close to the maximum score, and GI symptoms were significantly less in LLD-O compared with Ctl-O. CONCLUSION LDLT had no impact on donors' general, abdominal wall-related QoL or activity level. The performance of cholecystectomy apparently had no impact on the development of GI-related symptoms.

Abstract
Colorectal cancer is a worldwide health burden, with high incidence and mortality, especially in the advanced stages of the disease. Preclinical models are very important and valuable to discover and validate early and specific biomarkers as well as new therapeutic targets. In order to accomplish that, the animal models must replicate the clinical evolution of the disease in all of its phases. In this article, we review the existent mouse models, with their strengths and weaknesses in the replication of human cancer disease progression, with major focus on orthotopic models.

Abstract
Hepatocellular carcinoma and cholangiocarcinoma are the most common primary malignant liver tumors. Since the liver plays a key role in lipid metabolism, the study of serum phospholipid (PL) profiles may provide a better understanding of alterations in hepatic lipid metabolism. In this study, we used a high-resolution HILIC-LC-MS lipidomic approach to establish the serum phospholipidome profile of patients with liver cancer before (T0) and after tumor resection (T1) and a control group (CT) of healthy individuals. After the analysis of PL profiles, we observed that the phospholipidome of patients with liver cancer was significantly modified after the tumor resection procedure. We observed an upregulation of some phosphatidylcholine (PtdCho) species, namely, PtdCho(36:6), PtdCho(42:6), PtdCho(38:5), PtdCho(36:5), PtdCho(38:6) and choline plasmalogens (PlsCho), and/or 1-O-alkyl-2-acyl-glycerophosphocholine (PakCho) in patients with liver cancer at T0 compared to the CT group, and a downregulation after tumor resection (T1) when compared to T0. These results show that LC-MS can detect different serum PL profiles in patients with liver cancer, before and after tumor resection, by defining a specific PL fingerprint that was used to determine the effect of tumor and tumor resection on lipid metabolism.

Abstract
Gallbladder neuroendocrine carcinoma is a very rare entity, accounting for <0.2% of all neuroendocrine
tumours [1]. Of the cases described in the literature, the initial presentation is usually locally advanced or
even with disseminated disease [2]. In this paper we report the case of a 43-year-old female patient with an
incidental diagnosis of gallbladder neuroendocrine carcinoma. Although clinical presentation is the most
common, it is a very rare condition that poses a therapeutic and prognostic challenge.

Abstract
Cholangiocarcinoma (CC) is an aggressive liver tumor with limited therapeutic options. Natrium-iodide symporter (NIS) mediates the uptake of iodine by the thyroid, representing a key component in metabolic radiotherapy using iodine-131 (131I) for the treatment of thyroid cancer. NIS expression is increased in CC, providing the opportunity for a novel therapeutic approach for this type of tumor. Thus, in this study, we aimed to evaluate therapeutic efficacy of 131I in two human CC cell lines. Uptake experiments analyzed the 131I uptake profiles of the tumor cell lines under study. The cells were irradiated with various doses of 131I to evaluate and characterize the effects of metabolic radiotherapy. NIS protein expression was assessed by immunofluorescence methods. Cell survival was evaluated by clonogenic assay and flow cytometry was used to assess cell viability, and the type of death and alterations in the cell cycle. The genomic and epigenetic characterization of both CC cells was performed before and after irradiation. NIS gene expression was evaluated in the CC cells by RT-qPCR. The results revealed that CC cells had a higher expression of NIS. 131I induced a decrease in cell survival in a dose-dependent manner. With the increasing irradiation dose, a decrease in cell viability was observed, with a consequent increase in cell death by initial apoptosis. Karyotype and array comparative genomic hybridization (aCGH) analyses revealed that both CC cell lines were near-triploid with several numerical and structural chromosomal rearrangements. NIS gene expression was increased in the TFK-1 and HuCCT1 cells in a time-dependent manner. On the whole, the findings of this study demonstrate that the presence of NIS in cholangiocarcinoma cell lines is crucial for the decreased cell viability and survival observed following the exposure of cholangiocarcinoma cells to 131I.

Abstract
Afferent loop syndrome is a rare complication after gastrectomy with Billroth II or Roux-en-Y reconstruction, caused by an obstruction in the proximal loop. The biliary stasis and bacterial overgrowth secondary to this obstruction can lead to repeated episodes of acute cholangitis. We present the case of a male patient who had previously undergone gastrectomy with Roux-en-Y reconstruction and later experienced multiple episodes of acute cholangitis secondary to choledocolithiasis. He underwent an open exploration of the bile ducts with choledocolitotomy, but the events of cholangitis persisted. Further investigation permitted to identify a dilation of the biliary loop of the Roux-en-Y anastomosis, suggesting enterobiliary reflux as the cause of recurrent acute cholangitis. Therefore, a bowel enterectomy and new jejunojejunostomy were undertaken, and normal biliary flow was re-established. The surgical treatment is mandatory in benign causes, leading to the resolution of the obstruction and subsequent normalisation of bile flow.

Abstract
Acute pancreatitis (AP) is a severe inflammation of the pancreas presented with sudden onset and severe abdominal pain with a high morbidity and mortality rate, if accompanied by severe local and systemic complications. Numerous studies have been published about the pathogenesis of AP; however, the precise mechanism behind this pathology remains unclear. Extensive research conducted over the last decades has demonstrated that the first 24 h after symptom onset are critical for the identification of patients who are at risk of developing complications or death. The identification of these subgroups of patients is crucial in order to start an aggressive approach to prevent mortality. In this sense and to avoid unnecessary overtreatment, thereby reducing the financial implications, the proper identification of mild disease is also important and necessary. A large number of multifactorial scoring systems and biochemical markers are described to predict the severity. Despite recent progress in understanding the pathophysiology of AP, more research is needed to enable a faster and more accurate prediction of severe AP. This review provides an overview of the available multifactorial scoring systems and biochemical markers for predicting severe AP with a special focus on their advantages and limitations.

Abstract
Background Hemorrhagic rupture of a hepatic cyst is rare. To date, very few cases have been reported in the literature. Case Report A patient with a history of a suspected liver hydatid cyst presented to the emergency department with abdominal pain and fever. She was admitted with the presumptive diagnosis of acute cholecystitis. During hospitalization, the patient presented with hemodynamic instability and abrupt worsening of the abdominal pain. The abdominal angio-chemotherapy scan showed an abundant free peritoneal effusion and an apparent effacement of the anterior wall of a hepatic cyst of 16 cm. The patient underwent an exploratory laparotomy, deroofing of the cyst, and peritoneal lavage. The anatomopathological results showed a simple hepatic cyst. Discussion Hemorrhagic rupture of simple hepatic cysts is a life-threatening complication and, although rare, should be included in the differential diagnosis of sudden abdominal pain in patients with a history of simple hepatic cysts.

Abstract
Hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA) represent the most common primary liver malignancies whose outcome is influenced by the immune response. In the present study, we evaluated the tumor-infiltrating leukocyte (TIL) populations in 21 HCC patients and 8 CCA patients by flow cytometry immediately after the surgical procedure. Moreover, CD4+ T cells, CD8+ T cells, monocytes, and macrophages were purified by cell sorting for further analysis of gene expression by quantitative reverse-transcription polymerase chain reaction. Regarding tumor-infiltrating macrophages, we observed a significantly higher expression of markers associated with M2 phenotype and a higher expression of PD-L1 in patients with HCC in comparison to CCA. In addition, for HCC patients, we found a significant increase in the expression of CD200R in macrophages from tumors that were in grade G3-G4 as compared to tumors in grade G1-G2. Besides, a significantly higher frequency of tumor-infiltrating lymphocytes, CD8+CD56+ T cells, and natural killer cells was detected in HCC biopsies in comparison to CCA. In summary, this study has revealed functional and phenotypic differences in TIL cell subpopulations between CCA and HCC, as well as among different histopathological grades and tumor aggressiveness degrees, and it has provided evidence to better understand the tumor immune microenvironment of CCA and HCC.

Abstract
INTRODUCTION Excessive portal venous pressure in the liver remnant is an independent factor in the occurrence of posthepatectomy liver failure and small-for-size syndrome. The baseline portal pressure prior to hepatectomy was not considered previously. The aim of this study is to assess the impact of portal pressure change during hepatectomy on the patient outcome. MATERIAL AND METHODS Prospective observational study including 30 patients subjected to intraoperative measurement of portal pressure before and after hepatectomy. This variation was related to the patient outcome. Control group evaluation was assessed. Patient, disease and procedure features were considered. The optimal cut-off of portal pressure variation was determined. Linear regression or logistic regression was applied to identify predictors of the outcome. RESULTS The univariate analysis showed that portal pressure increase after hepatectomy was associated with coagulation impairment in the first 30 postoperative days (p < 0.05), and with the occurrence of major complications (p = 0.01), namely hepatic failure (p = 0.041). The multivariate analysis showed that portal venous pressure increase ≥ 2 mmHg is an independent factor for worse outcomes. DISCUSSION As in previous studies, this study concludes that, after hepatectomy, in addition to the functional liver remnant, other factors are responsible for deterioration of liver function and patient outcome, such as the portal pressure increase and the exposure to chemotherapy prior to hepatectomy. This work may influence the definition of future indications for portal influx modulation. CONCLUSION Patient outcomes are influenced by the portal venous pressure increase: an increment ≥ 2 mmHg after hepatectomy seems to increase the risk of major complications.

Abstract
Acute pancreatitis (AP) is a severe disease associated with high morbidity and mortality. Clinical studies can provide some data concerning the etiology, pathophysiology, and outcomes of this disease. However, the study of early events and new targeted therapies cannot be performed on humans due to ethical reasons. Experimental murine models can be used in the understanding of the pancreatic inflammation, because they are able to closely mimic the main features of human AP, namely their histologic glandular changes and distant organ failure. These models continue to be important research tools for the reproduction of the etiological, environmental, and genetic factors associated with the pathogenesis of this inflammatory pathology and the exploration of novel therapeutic options. This review provides an overview of several murine models of AP. Furthermore, special focus is made on the most frequently carried out models, the protocols used, and their advantages and limitations. Finally, examples are provided of the use of these models to improve knowledge of the mechanisms involved in the pathogenesis, identify new biomarkers of severity, and develop new targeted therapies.

Abstract
The deep peribiliary glands (DPBG) are a niche of progenitor cells in the wall of the biliary duct (BD) and are the second line of multiplication when severe lesion of the epithelium occurs. Previous studies have identified DPBG injury as a cause of post-liver transplant (LT) biliary stenosis; this complication is a major cause of post-LT morbidity. The incidence of biliary stenosis in our center is high (38.1%). This study evaluates the lesion of DPBG in response to ischemia. Graft BD was collected in adult LT between August 2016-July 2017, from donation after brain death. Samples of 45 grafts were collected at 2 moments: BD1-during graft preparation and BD2-before biliary anastomosis. Histological analysis of the samples was performed and then classified according to degree of lesion (0, ≤50%, and >50%). A comparison was made between the degree of lesion and graft ischemia, graft histology, donor, and procurement variables. The DPBG lesion was more frequent in BD2 (20.9% vs 7%, P = .079). BD2 lesions with DPBG lesions had higher medians and means at all times of ischemia. The difference was greater in the warm ischemia time (0: 43.3 ± 12.53 minutes vs ≤50%: 52.4 ± 14.38 minutes, P = .068). The group of BD1 with DPBG lesion presented superior median cold ischemia time (CIT). In the analysis of the remaining variables there were also no statistically significant differences. We concluded that during the period of CIT there is already lesion of the DPBG, which increases after reperfusion of the graft, in greater association with longer warm ischemia time.

Abstract
BACKGROUND/AIMS We measured changes in mitochondrial function and bioenergetics that occur during ischemia/ reperfusion in fresh liver samples of patients undergoing liver transplantation. These variations correlated with markers of liver function and clinical outcome. Ischemia/reperfusion injury related to liver transplantation affects mitochondrial function and bioenergetics. Experimental studies were conducted to identify the role of bioenergetics and mitochondrial dysfunction. To the best of our knowledge, no investigation of these two factors' impacts on liver transplantation has been performed. METHODS This was a prospective study of 28 patients who underwent liver transplantation. We measured parameters of mitochondrial function and bioenergetics in biopsies performed during the procedure. RESULTS We observed a statistically significant reduction in mitochondrial membrane potential, an increase in lag phase, and decreases in mitochondrial respiration and adenosine triphosphate content (P<0.010). Higher postoperative aminotransferase peaks correlated with worse mitochondrial function; mitochondrial respiration correlated with arterial lactate (P<0.010). CONCLUSION There is a relationship between mitochondrial function and ischemia/reperfusion injury. The future use of these clinical markers as prognostic factors may allow early identification of post-transplant liver failure and may indicate the need to perform a new transplant.

Abstract
The organ preservation paradigm has changed following the development of new ways to preserve organs. The use of machine perfusion to preserve organs appears to have several advantages compared with conventional static cold storage. For liver transplants, the temperature control provided by machine perfusion improves organ preservation. In this experimental study, we measured the effects of different temperatures on mitochondrial bioenergetics during the reperfusion phase. An experimental model of ex-vivo liver transplantation was developed in Wistar rats (Rattus norvegicus). After total hepatectomy, cold static preservation occurred at 4ºC and reperfusion was performed at 37ºC and 32ºC using a Langendorff system. We measured parameters associated with mitochondrial bioenergetics in the livers. Compared with the livers that underwent normothermic reperfusion, mild hypothermia during reperfusion caused significant increases in the mitochondrial membrane potential, the adenosine triphosphate content, and mitochondrial respiration, and a significant reduction in the lag phase (all P < 0.001). Mild hypothermia during reperfusion reduced the effect of ischemia-reperfusion injury on mitochondrial activity in liver tissue and promoted an increase in bioenergetic availability compared with normothermic reperfusion.

Abstract
INTRODUCTION Liver resection combined with neoadjuvant chemotherapy (NAC) has reported notable results in patients with colorectal liver metastases (CRLM). Tumoral response to NAC is associated with specific histopathologic patterns with prognostic implications. The main objective of this study was to evaluate the influence of pathological findings on overall survival (OS), disease-free survival (DFS) and liver recurrence-free survival (LRFS). PATIENTS AND METHODS Analysis of clinical and outcome data from 110 patients who underwent first CRLM resection between January 2010 and July 2013. Blinded pathological review of histological material of several parameters: resection margin, tumor regression grade (TRG), tumor thickness at the tumor-normal interface (TTNI) and the growth pattern (GP). RESULTS The median survival following hepatic resection was 52 months and 3- and 5- year Kaplan-Meier estimates were 69 and 48%, respectively. Seventy-four patients developed recurrent disease. Oxaliplatin-based chemotherapy was significantly associated with a pushing GP. A positive resection margin was an independent predictor of decreased DFS (p = 0.018) but not of decreased OS. LRFS was strongly reduced by the absence of histologic tumor response (p = 0.018). The pushing pattern had an adverse impact on both OS (p = 0.007) and DFS (p = 0.004) on multivariate analysis. CONCLUSION The prognostic value of histopathological features in patients who underwent CRLM's resection is undeniable. The pushing GP was related with worse prognosis. Further studies are required to clarify the biological mechanisms underlying these findings in order to enhance a more personalized and efficient treatment of these patients.

Abstract
Colorectal cancer (CRC) is the second most frequent and fatal cancer in Western countries. Understanding its biology with different incidence along the colon and rectum, genetic profile and how these factors contribute to local/distant progression, has been hampered by the lack of a suitable CRC model. We report a reproducible model, using human CRC cell lines (CL) (WiDr, LS1034, C2BBe1) injected (1 × 107 cells/animal) in RNU rats (n = 55) which underwent cecostomy and descending colostomy with mucosal-cutaneous fistula of the sigmoid colon. CL were characterized by immunohistochemistry: CK20, CDX2, P53, vimentin, Ki67, CD44, CD133, E-cadherin, β-catenin and CEA; cancer stem cells-immune system interaction was studied and tumor progression was assessed with nuclear medicine imaging (99mTc-MIBI). Animals developed locally invasive tumors and with WiDr neural invasion was registered. Cancer stem cells were detected in WiDr (CD44 positive). All the cell lines stimulated the immune system, being WiDr the most aggressive. Imaging studies demonstrated tumor uptake. With this CRC model we can study the microenvironment role and tumor-stroma interactions. All CL developed primary disease, but only the WiDR established neural invasion which may represent a metastatic pathway. This model can help unveiling the underlying metastatic mechanisms, and ultimately test better therapeutic approaches for CRC.

Abstract
Ischemia/reperfusion (I/R) injury in liver transplantation can disrupt the normal activity of mitochondria in the hepatic parenchyma. This potential dysfunction of mitochondria after I/R injury could be responsible for the initial poor graft function or primary nonfunction observed after liver transplantation. Thus, determining the mechanisms that lead to human hepatic mitochondrial dysfunction might contribute to improving the outcome of liver transplantation. Furthermore, early identification of novel prognostic factors involved in I/R injury could serve as a key endpoint to predict the outcome of liver grafts and also to promote the early adoption of novel strategies that protect against I/R injury. Here, we briefly review recent advances in the study of mitochondrial dysfunction and I/R injury, particularly in relation to liver transplantation. Next, we highlight various pharmacological therapeutic strategies that could be applied, and discuss their relationship to relevant mitochondrion-related processes and targets. Lastly, we note that although considerable progress has been made in our understanding of I/R injury and mitochondrial dysfunction, further investigation is required to elucidate the cellular and molecular mechanisms underlying these processes, thereby identifying biomarkers that can help in evaluating donor organs.

Abstract
It was reported that prevention of acute portal overpressure in small-for-size livers by inflow modulation results in a better postoperative outcome. The aim is to investigate the impact of portal blood flow reduction by splenic artery ligation after major hepatectomy in a murine model. Forty-eight rats were subjected to an 85% hepatectomy or 85% hepatectomy and splenic artery ligation. Both groups were evaluated at 24, 48, 72 and 120 post-operative hours: liver function, regeneration and viability. All methods and experiments were carried out in accordance with Coimbra University guidelines. Splenic artery ligation produces viability increase after 24 h, induces a relative decrease in oxidative stress during the first 48 hours, allows antioxidant capacity increment after 24 h, which is reflected in a decrease of half-time normalized liver curve at 48 h and at 72 h and in an increase of mitotic index between 48 h and 72 h. Splenic artery ligation combined with 85% hepatectomy in a murine model, allows portal inflow modulation, promoting an increase in hepatocellular viability and regeneration, without impairing the function, probably by inducing a less marked elevation of oxidative stress at first 48 hours.

Abstract
Hepatocellular carcinoma (HCC) is increasingly considered an issue of global importance. Its rates of incidence and mortality have been markedly increasing over the last decades. Among risk factors, some should be highlighted, namely the infections by hepatitis B and C virus, as well as clinical cases of cirrhosis. HCC is characterized as asymptomatic disease in the initial stages which most often leads to a late diagnosis. At molecular and genetic level HCC represents a highly complex tumor entity, including a wide variety of mutations, thus accounting for different mechanisms of resistance towards therapeutic approaches. In particular, mutations of the TP53 gene, as well as a deregulation between the expression of pro- and anti-apoptotic proteins of the BCL-2 family are observed. Regarding treatment modalities, surgical procedures offer the best chance of cure, however, due to a late diagnosis, most of concerned patients cannot be subjected to them. Chemotherapy and radiotherapy are also ineffective, and currently, the treatment with sorafenib is the most commonly used systemic therapy although it can only increase the patient survival for some months. In this sense, a quick and accurate investigation is of utmost importance in order to develop ways of early diagnosis as well as new therapies for HCC.

Abstract
Liver, the largest intern organ of the human body, is responsible for several vital tasks such as digestive and excretory functions, as well as for nutrients storage and metabolic functions, synthesis of new molecules and purification of toxic chemicals. Cirrhosis, fibrosis and hepatocellular carcinoma are the most prevalent liver diseases. Despite all the studies performed so far, treatment options for these diseases are very limited. For this reason, it is urgent to find effective therapies for these pathologies. Several studies have been performed during the last decade about the possible application of human amniotic membrane in hepatic diseases therapy. Promising results about human amniotic membrane or its derived cells, in vitro and in vivo, applications in fibrosis, cirrhosis and hepatocellular carcinoma were already published. Since it is an attractive study area, it is becoming a dynamic scientific subject. However, the action mechanisms of human amniotic membrane and its derived cells in hepatic diseases therapy must be precisely known in order that this promising therapy could be clinically used.

Abstract
BACKGROUND Liver regeneration requires an enormous energy supply. Experimental evidence suggests that mitochondrial function is of paramount importance for liver regeneration. However, this has not been investigated in the clinical setting. We aimed to: (i) evaluate changes in mitochondrial function during hepatectomy, especially after hepatic pedicle clamping; and (ii) correlate these changes with postoperative hepatocellular function and clinical outcome. MATERIALS AND METHODS Prospective study of thirty patients undergoing hepatectomy. Measurement of mitochondrial membrane potential, respiration and adenosine triphosphate content in intra-operative liver biopsies performed in nonresected parenchyma. Correlation of findings with duration of hepatic pedicle clamping, postoperative markers of hepatocellular necrosis and function (aminotransferases, arterial lactate, international normalized ratio, bilirubin), and morbidity. RESULTS Longer hepatic pedicle clamping was associated with worse mitochondrial depolarization (r = -0·519; P = 0·011) and longer lag phase (r = 0·568; P = 0·006). Higher postoperative peak aminotransferases, international normalized ratio and bilirubin correlated with worse mitochondrial function (P < 0·05). After major hepatectomy, mitochondrial respiration correlated with postoperative arterial lactate clearance (r = 0·756; P = 0·049). Mitochondrial bioenergetic parameters were significantly decreased in patients with liver-specific morbidity and postoperative liver failure (P < 0·05). On multivariate analysis, decrease in mitochondrial potential was an independent risk factor for liver-specific morbidity (OR = 13·7; P = 0·043). Worse lag phase was highly predictive of posthepatectomy liver failure (area under the curve: 0·933; P = 0·008). CONCLUSIONS There is a relationship between mitochondrial function, duration of hepatic pedicle clamping and clinical outcome after hepatectomy. Mitochondrial bioenergetics can potentially translate into clinical practice, assisting in earlier diagnosis of postoperative liver dysfunction, and as a target for future pharmacological therapies.

Abstract
Hepatocellular carcinoma (HCC) is the most common primary liver tumor (PLT), with cholangiocarcinoma (CC) being the second most frequent. Glucose transporter 1 (GLUT-1) expression is increased in PLTs and therefore it is suggested as a therapeutic target. Flavonoids, like quercetin, are GLUT-1 competitive inhibitors and may be considered as potential therapeutic agents for PLTs. The objective of this study was evaluation of quercetin anticancer activity in three human HCC cell lines (HepG2, HuH7, and Hep3B2.1-7) and in a human CC cell line (TFK-1). The possible synergistic effect between quercetin and sorafenib, a nonspecific multikinase inhibitor used in clinical practice in patients with advanced HCC, was also evaluated. It was found that in all the cell lines, quercetin induced inhibition of the metabolic activity and cell death by apoptosis, followed by increase in BAX/BCL-2 ratio. Treatment with quercetin caused DNA damage in HepG2, Hep3B2.1-7, and TFK-1 cell lines. The effect of quercetin appears to be independent of P53. Incubation with quercetin induced an increase in GLUT-1 membrane expression and a consequent reduction in the cytoplasmic fraction, observed as a decrease in (18)F-FDG uptake, indicating a GLUT-1 competitive inhibition. The occurrence of synergy when sorafenib and quercetin were added simultaneously to HCC cell lines was noticed. Thus, the use of quercetin seems to be a promising approach for PLTs through GLUT-1 competitive inhibition.

Abstract
PURPOSE To investigate the impact of selective hepatic artery clamping (SHAC) in hepatocellular function. METHODS Three groups of Wistar male rats were subjected to SHAC ischemia period of 60min: Group A continuous SHAC were subjected to SHAC ischemia period of 60min, Group B intermittent SHAC of 30min with 5min of reperfusion and Group C intermittent SHAC of 15min with 5min of reperfusion. Animals without SHAC were included-Group D. To evaluate hepatocellular function blood markers and hepatic extraction function (HEF) using 99mTc-mebrofenin were performed before and after surgery. Flow cytometry was used to analyze oxidative stress and cell viability. RESULTS A mortality rate of 7.6% in Group A was observed. HEF maintained normal values between the groups. Flow cytometry demonstrated no significant differences between the groups in viability, type of cell death as well as in the production of reactive oxygen species. CONCLUSIONS The selective hepatic artery clamping compared to other clamping techniques results on increased cell viability and decreased hepatocyte death. The SHAC is a potential alternative to decrease per-operative bleeding while maintaining hepatocellular function.

Abstract
Solitary necrotic nodule of the liver is a rare entity of unknown aetiology. We describe the case of a 59-year-old woman reporting sporadic right upper quadrant pain. An abdominal CT scan revealed a liver nodule located in segment 4. The complementary investigation was unable to identify the neoplastic lesion, and its surgical resection was performed, with an uneventful recovery. Pathological examination revealed a 'solitary necrotic nodule of the liver.' The patient remains asymptomatic and free of recurrence 3 years after surgery. This case corroborates that despite the advances in liver imaging and biopsy, liver nodules are sometimes a diagnostic challenge; quite often, only its surgical resection allows a definitive diagnosis.

Abstract
Hepatocellular carcinoma is the fifth most common cancer in men and the seventh in women, as is diagnosed in more than half a million individuals worldwide every year. In Portugal, its incidence and mortality rates are low compared to other types of cancers. In Brazil, in the city of São Paulo, according to data released by the Brazilian Unified Health System (Sistema Único de Saúde - SUS), the incidence of primary liver cancer was 2.07/100,000 inhabitants. Although the vast majority of cases (85%) mainly affect developing countries, especially where infection by hepatitis B virus (HBV) is endemic, the incidence in developed countries is increasing. This pathology is associated with several risk factors, not only environmental but also genetic, generating an increasing interest in attaining a better understanding of this disease, which is still associated with very late diagnosis and poor prognosis. Of the available treatments, few patients benefit from their scanty advantages, increasingly stimulating research of new forms of treatment against this disease. This review aimed to briefly but fully identify risk factors, molecular and biochemical pathways, pathophysiology, diagnosis, and possible clinical approaches of hepatocellular carcinoma.

Abstract
Primary splenic angiosarcoma, a very rare mesenchymal tumour of endothelial cell origin, comprises 2.6% of all cases of angiosarcoma and 10% of all primitive splenic tumours. Clinical presentation is usually unspecific, with abdominal pain and anaemia. Rupture is a rare complication and should prompt emergency splenectomy. Prognosis is usually poor because of liver, lung or bone metastases. We describe the case of an 80-year-old woman admitted to the emergency room with syncope, hypotension and vomiting. She stabilised after fluid resuscitation. Investigations showed anaemia, a large, heterogeneous spleen and free fluid in the abdominal cavity. She underwent emergency splenectomy. Pathology revealed primary splenic angiosarcoma. The postoperative period was complicated by respiratory failure but the patient made an otherwise uneventful course and was discharged 2 weeks after surgery. Six months after the operation she remains free of disease with no adjuvant treatment.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is the most common primary neoplasm of the liver. A major proportion of HCCs also present mutation of the gene that encodes p53, which confers chemoresistance. The main goal of this work is to investigate the effect of cisplatin, doxorubicin and 5-fluoruracil (5-FU) in three human HCC cell lines which differ in p53 expression. METHODS HepG2 (expressing normal p53), HuH7 (expressing mutated p53) and Hep3B2.1-7 (not expressing p53) cell lines were cultivated in the presence of cisplatin, doxorubicin and 5-FU. Cell proliferation was evaluated by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay (MTT assay). The type of cell death and Bax and Bcl2 activation were assessed by flow cytometry. RESULTS It was found that for all of the cell lines studied, the agent that gave the most satisfactory results was doxorubicin. 5-FU demonstrated no activity in these cell lines. CONCLUSIONS For all the cell lines studied, doxorubicin was the most satisfactory agent. In HepG2 and HuH7 cell lines, it can activate Bax with statistical significance.

Abstract
The mechanisms linking immune responses and inflammation with tumor development are not well understood. Here, we show that the soluble form of the extracellular matrix proteoglycan decorin controls inflammation and tumor growth through PDCD4 (programmed cell death 4) and miR-21 (microRNA-21) by two mechanisms. First, decorin acted as an endogenous ligand of Toll-like receptors 2 and 4 and stimulated production of proinflammatory molecules, including PDCD4, in macrophages. Second, decorin prevented translational repression of PDCD4 by decreasing the activity of transforming growth factor-β1 and the abundance of oncogenic miR-21, a translational inhibitor of PDCD4. Moreover, increased PDCD4 abundance led to decreased release of the anti-inflammatory cytokine interleukin-10, thereby making the cytokine profile more proinflammatory. This pathway operates in both pathogen-mediated and sterile inflammation, as shown here for sepsis and growth retardation of established tumor xenografts, respectively. Decorin was an early response gene evoked by septic inflammation, and protein concentrations of decorin were increased in the plasma of septic patients and mice. In cancer, decorin reduced the abundance of anti-inflammatory molecules and increased that of proinflammatory molecules, thereby shifting the immune response to a proinflammatory state associated with reduced tumor growth. Thus, by stimulating proinflammatory PDCD4 and decreasing the abundance of miR-21, decorin signaling boosts inflammatory activity in sepsis and suppresses tumor growth.

Abstract
OBJECTIVE To evaluate the long-term results of aggressive treatment of HCC recurrence. METHODS Two hundred and nine consecutive patients underwent hepatic resection for HCC in our hospital. Tumour recurrence was diagnosed in 97 (51%) of the 190 patients with curative resection. Sixteen underwent hepatic resection: two right hepatectomies, one three-segmentectomy, one left hepatectomy, five two-segmentectomies, six segmental resections and one subsegmentectomy. Two patients with metastasis in the spine were submitted to a vertebral body resection. Twenty-five patients were treated with percutaneous ethanol injection or intra-arterial chemoembolization. Fifty-four patients with a poor performance status and liver function or multiple extra hepatic recurrences did not receive any treatment. RESULTS There were no operative deaths. The postoperative mortality rate was 5.5% (one patient). The cumulative overall survival after the second resection was respectively 89%, 46% and 31% at 1, 3 and 5 years. There was a significant difference in survival between patients treated with repeat resection and those submitted to a non-surgical or conservative treatment (p<0.0001). There were no differences in operative deaths, postoperative mortality and morbidity between the first and second hepatic resection. CONCLUSIONS Aggressive management with combined resection or loco regional therapy for intrahepatic recurrence and resection of isolated extra-hepatic recurrence may offer long-term survival in selected patients. Second liver resection for recurrence of HCC can be safely performed.

Abstract
BACKGROUND/AIMS Certain prognostic factors affect the postoperative mortality and long-term survival of patients following hepatic resection for hepatocellular carcinoma (HCC) and may change the surgical strategy. METHODOLOGY 209 consecutive patients underwent hepatic resection for HCC in our hospital. Seventy-three patients underwent major resection and 136 underwent minor resections. We looked for correlations between clinical, biological, surgical and pathological factors and postoperative mortality, disease-free survival and overall survival. RESULTS The postoperative mortality rate was 7.7% (it fell to 0% in the last two years). The cumulative overall five-year survival rate was 27% and the overall disease-free survival rate was 7.3%. Multivariate analysis identified: (1) two independent prognostic factors for postoperative mortality: age and tumor size; (2) one risk factor for tumor recurrence: intraoperative blood transfusion, and (3) three independent prognostic factors for overall survival: infiltrative tumor type, surgical margin <10 mm and intraoperative blood transfusion. CONCLUSIONS In addition to routine staging of the tumor, the preoperative evaluation of HCC patients should include tests to determine whether the tumor is infiltrative or expansive and whether it will be possible to obtain a surgical margin (>10 mm). This procedure should make it possible to propose an appropriate neoadjuvant treatment only to these patients. The prevention of intraoperative bleeding or blood transfusion should improve the disease-free and overall survival rates in HCC patients.

Abstract
Decorin is a well-known, ubiquitous proteoglycan that is a normal component of the ECM. Upon transgenic expression of decorin, tumor cells with diverse histogenetic background overexpress p21WAF1, a potent inhibitor of cyclin-dependent kinase activity, become arrested in G1, and fail to generate tumors in immunocompromised animals. Because decorin is a secreted protein, it has been recently suggested that decorin could act as an autocrine and paracrine regulator of tumor growth. Here, we demonstrate that adenovirus (Ad)-mediated transfer and expression of human decorin cDNA induced in vivo apoptosis of xenograft tumor cells in nude mice. This oncolytic activity was observed when the Ad vector encoding the decorin cDNA was injected intratumorally (i.t.) or i.v. Importantly, i.t. injection of the decorin Ad vector led to growth inhibition of the injected tumor associated with similar growth inhibition of a distant contralateral tumor, demonstrating a distant decorin antitumoral effect. Immunochemistry against human decorin and decorin quantitation in tumors confirmed that decorin migrated to the tumor distant site. Furthermore, decorin effect was specific to tumor cells, because neither apoptosis nor growth inhibition were observed in nontumoral human cells such as hepatocytes, endothelial cells, and fibroblasts, despite p21 overexpression.
