Role of poorly differentiated cluster in gastric cancer: is it a new prognosis factor?

BACKGROUND: Poorly differentiated Clusters (PDCs) of tumor cells composed of more than five elements have been recently described in gastrointestinal cancers and correlate with a worse prognosis. Our study aims to investigate PDC occurrence in a series of patients with gastric cancer and correlate it with lymph node status and clinical outcome. MATERIAL AND METHODS: 50 patients were included in the study; PDCs count was graduated as G1, G2, and G3 according to Ueno classification (PDCs count at 20× <5, 5-9 and ≥10 respectively). We collected several clinicopathologic variables such as tumor location, pTNM stage, vascular or perineural invasion, and lymph-node ratio for each case. RESULTS: The presence of PDCs was related to vascular invasion (p < .013) and recurrence event (p < .027). When the population was categorized according to the number of PDCs, a significant correlation was found with the presence of lymph node metastasis (p < .000), the Lymph Node Ratio (p < .002), WHO stage at the diagnosis (p < .000) and vascular invasion (p < .001). At the univariate and multivariate analysis, PDCs were found as an independent risk factor for recurrence (HR 1.94; CI 95% 1.209-3.121; p < .006 and HR 0.401; CI 95% 0.187-0.862; p < .017 respectively). The Kaplan-Meier curves for OS and DFS showed a significant association between PDCs and shorter time to recurrence or survival. CONCLUSION: PDC is a strong prognostic factor in gastric cancer, easily detectable, and feasible. As far as we know, this is the first report in Literature of a strong correlation between PDC and survival in patients with operated gastric cancer.

Prognostic factors in gastric cancer patients: a 10-year mono-institutional experience.

Introduction: Gastric cancer (GC) is one of the main causes of death from cancer globally. Long-term survival, especially in Western countries, remains dismal, with no significant improvements in recent years. Therefore, precise identification of clinical and pathological risk factors is crucial for prognosis, as it allows a better selection of patients suitable for oncologically radical treatments and contributes to longer survivals. Methods: We devised a retrospective observational longitudinal study over 10 years of experience with GC patients operated with curative intent. Results: Several factors were thoroughly investigated in a multivariate analysis to look for significance as independent risk factors for disease-free survival. Our results showed that only BMI, pTNM, and lymph node ratio expressed hazard ratios with implications for survival in our series of patients. Discussion: Although limited by the retrospective nature of the study, this is one of the few cancer reports from Northern Italy showing results over 10 years, which may in our view, have an impact on decision-making processes for multidisciplinary teams dedicated to the care of gastric cancer patients.

Strong impact of sarcopenia as a risk factor of survival in resected gastric cancer patients: first Italian report of a Bicentric study.

Gastric cancer (GC) accounts for 4% of all cancers in Europe. Sarcopenia is a complex syndrome characterized by a loss of muscle mass and function associated with age, often present in neoplastic patients. Recently, several studies have shown a significant association between sarcopenia and poor prognosis in various pathological conditions. The current observational retrospective study investigates the association between sarcopenia and overall survival (OS) and recurrence-free survival (RFS) in patients with GC undergoing up-front surgery with curative intent. Resected GC patients' clinical records and CT images were retrospectively assessed. The preoperative CT calculation of the skeletal muscle index (SMI) at L3 level allowed us to categorize patients as sarcopenic or not. Kaplan-Meyer and univariate and multivariate Cox regression analyses were performed to determine the difference in survival and presence of independent prognostic factors. Fifty-five patients, 28 male and 27 female, out of 298 studied for gastric cancer were enrolled in the current study from two cancer referral centers in Italy. The preoperative CT calculation of the SMI at L3 level allowed us to identify 39 patients with and 16 without sarcopenia. A statistically significant difference between the sarcopenic and non-sarcopenic groups was observed in both OS and RFS (p < 0.023; p < 0.006). Moreover, sarcopenia was strongly correlated to a higher risk of recurrence in univariate and multivariate analysis (p < 0.02). Sarcopenia can be considered a critical risk factor for survival in patients with resectable GC treated with up-front surgery. Identifying sarcopenic patients at the time of diagnosis would direct selection of patients who could benefit from early nutritional and/or physical treatments able to increase their muscle mass and possibly improve the prognosis. More extensive multicenter studies are needed to address this issue.

Combined liver-kidney transplantation in patients infected with human immunodeficiency virus.

Although human immunodeficiency virus (HIV) infection has been a major global health problem for almost 3 decades, with the introduction of highly active antiretroviral therapy in 1996 and effective prophylaxis and management of opportunistic infections, mortality from acquired immunodeficiency syndrome has decreased markedly. In developed countries, this condition is now being treated as a chronic condition. As a result, rates of morbidity and mortality from other medical conditions leading to end-stage liver, kidney, and heart disease are steadily increasing in individuals with HIV. Because the definitive treatment for end-stage organ failure is transplantation, the demand for it has increased among HIV-infected patients. For these reasons, many transplant centers have eliminated HIV infection as a contraindication to transplantation, as a result of better patient management and demand.

Liver transplantation in patients aged 65 and over: a case-control study.

INTRODUCTION: The average age of patients undergoing liver transplantation (LT) is consistently increasing. The aim of this case-control study is to evaluate survival and outcome of patients ≥65 yr compared to younger patients undergoing LT. MATERIALS AND METHODS: From 10/00 to 4/08 we performed 330 primary LT, 31 (9.4%) of these were in patients aged 65-70. Following a case-control approach, we compared these patients with 31 patients aged between 41 and 64 yr and matched according to sex, LT indication, viral status, cadaveric/living donor, LT timing, and Model for End-Stage Liver Disease (MELD) score. RESULTS: There were no statistically significant differences in demographic and surgical donor characteristics. The mean MELD score was under 18 in both groups. Post-LT complications occurred with a similar incidence in the two groups. one-, three-, and five-yr survival was 83.9%, 80.6%, and 80.6%, respectively, for the elderly group, and 80.6%, 73.8%, and 73.8%, respectively, for the young group (p = 0.61). DISCUSSION: Patients aged between 65 and 70 with low MELD score who undergo LT have the same short- and middle-term survival expectancy, morbidity, and outcome quality as younger patients with the same indication and same pre-LT pathology severity, whatever they might be. Thus, chronological age alone should not deter LT workup in patients >65 and <70.

[Is there an age limit for radical surgery in case of tumors infiltrating the duodenum?]. / Per le neoplasie infiltranti il duodeno esiste un limite di età per una chirurgia radicale?

AIM: Radical resection is the only potential cure for pancreatic malignancies and a useful treatment for other benign diseases, such as pancreatitis. Over the last two decades, medical and surgical improvements have drastically changed the postoperative outcome of elderly patients undergoing pancreatic resection, and appropriate treatment for elderly potential candidates for pancreatic resection has become an important issue. METHODS: A hundred and five consecutive patients undergoing radical pancreatic resection between 2003 and 2007 at the Surgery Unit of the University of Modena, Italy, were considered and divided into two groups according to their age, i.e., over 75-year olds (group 1, 25 patients) and under 75-year-olds (group 2, 80 patients). The two groups were compared as regards to demographic features, American Society of Anesthesiologists scores, comorbidities, previous major surgery, surgical procedure, postoperative mortality, and morbidity. RESULTS: There were no significant differences between the two groups concerning postoperative mortality, and the duration of hospital stay and days in the postoperative Intensive Care Unit were also similar. Complications such as pancreatic fistulas, wound infections, and pneumonia were more frequent in the older group, but the differences were not statistically significant. CONCLUSION: In the light of these findings and as reported for other series, old age is probably not directly related with any increase in the rate of postoperative complications, but comorbidities (which are naturally related to the patients' previous life) may have a key role in the postoperative course.

Negative pressure wound therapy (NPWT) after cytoreductive surgery (CRS) and intraperitoneal chemotherapy (HIPEC) for peritoneal surface malignancies: preliminary report.

AIM: Surgical site (SSI) infection is a common complication that occurs in the post-operative period because it still has a decisive impact on the morbidity and mortality of patients and the costs associated with therapy and prolongation of hospitalization. In recent years, therefore, several authors have published their experience in the use of negative pressure prevention systems (NPWT) for the management of surgical wounds. Few authors in the literature have discussed the use of NPWT in patients undergoing cytoreductive surgery (CRS) for peritoneal surface malignancies associated with hyperthermic intraperitoneal chemotherapy (HIPEC). PATIENTS AND METHODS: Nineteen patients undergoing open surgery, of which 15 underwent CRS+HIPEC operations; in 2 cases the dressing was applied to patients undergoing colon surgery, 1 case after emergency laparotomy for intestinal occlusion in a patient with a BMI of 29 and 1 case after gastric surgery for a tumour. At the and of the surgery, NPWT was placed on the surgical site; the therapy includes a closed and sealed system which maintains a negative pressure between at -125 mmHg on the surgical wound and which remains in place for five days. RESULTS: The rationale for using an NPWT is to determine a barrier between the wound and external contamination, reducing wound tension and reducing the formation of seroma and hematoma. Moreover, during the HIPEC, several litres of water are used to wash the patient's abdominal cavity and then the patient is sutured again without the peritoneum, losing the function of protection from external microorganism and also of reabsorbing the intra-abdominal serum. A recent Cochrane collaboration about the application of NPWT demonstrates that it may reduce the rate of SSI compared with SSD, even if there is no sure evidence about the reduction of complications like seromas or dehiscence. CONCLUSION: After the analysis of the preliminary data, we confirm the possibility to start with a randomised clinical trial, as suggested by the literature.

Human immunodeficiency virus and liver transplantation: our point of view.

INTRODUCTION: Highly active antiretroviral therapy (HAART) has been able to improve the immune system function and survival of HIV patients with a consequent increase in the number of HIV patients affected by end-stage liver disease (ESLD). Between June 2003 and October 2006, 10 HIV-positive patients underwent liver transplantations in our center. METHODS: All patients were treated with HAART before transplantation; treatment was interrupted on transplantation day and was restarted once the patients' conditions stabilized. Five patients were hepatitis C virus (HCV)-positive, 3 were hepatitis B virus (HBV)-positive, and 2 were HBV-HCV coinfected. HIV viral load before transplantation was <50 copies/mL in all cases. CD4+ cell count before transplantation ranged between 144 and 530 c/microL. Immunosuppression was based on Cyclosporine (CyA) and steroid weaning for 8 patients, and on Tacrolimus and steroid weaning for 2 patients. RESULTS: Five patients were cytomegalovirus (CMV)-positive pp65 antigenemia posttransplantation, and 1 patient was EBV-positive; 2 patients had a coinfection with HHV6. Four patients suffered from a cholestatic HCV recurrent hepatitis treated with antiviral therapy (peginterferon and Ribavirin). Three patients died after transplantation. DISCUSSION: The outcome of liver transplantation in HIV patients was influenced by infections (HCV, CMV, and EBV) and Kaposi's Sarcoma. HCV recurrence was more aggressive, showing a faster progression in this patient population. Drug interaction between HAART and immunosuppressants occurs; longer follow-up and better experience may improve the management of these drug interactions.

Model for End-Stage Liver Disease (MELD) system to allocate and to share livers: experience of two Italian centers.

BACKGROUND: The use of the Model for End-stage Liver Disease (MELD) score to prioritize patients on liver waiting lists and to share organs among centers was effective according to US data, but few reports are available in Europe. MATERIALS AND METHODS: We evaluated the outcome of 887 patients listed between April 2004 and July 2006 in a common list by two transplant centers (University of Bologna [BO] and University of Modena [MO] ordered according to the MELD system. Patients with hepatocellular carcinoma had a score calculated according to their real MELD, tumor stage, and waiting time. RESULTS: Five hundred eighty-six (67%) patients were listed from BO and 291 (33%) from MO. The clinical features of recipients (sex, age, blood group, and real MELD) were comparable between centers. The number of liver transplantations performed was 307, and 273 (89%) recipients had a calculated MELD >or=20. Liver transplantations were equally distributed according to the number of patients listed: 215 out of 586 (36.7%) for BO and 92 out of 291 (31.6%) for MO. The median real MELD of patients transplanted was 20, and 246 out of 307 (80.1%) grafts transplanted were functioning. The dropouts from the list were 124 (14%), and 87 (70%) of these patients had a calculated MELD >or=20. CONCLUSION: The MELD system was effective to share livers among the two Italian centers. According to this policy, livers were allocated to the recipients with the highest probability of dropout and who had a satisfactory survival after liver transplantation.

Temporary porto-caval shunt utility during orthotopic liver transplantation.

INTRODUCTION: In liver transplantation (OLT) a porto-caval shunt is a well-defined technique practiced by many surgeons in several centers. METHODS: We considered 186 cadaveric OLT patients who underwent a cavo-cavostomy-type reconstruction; they were divided into two groups: those in whom we performed a porto-caval shunt (group A) and those in whose we did not (group B). We evaluated several variables: warm and total ischemia time, intraoperative blood and fresh frozen plasma transfusions, crystalloid and colloid requirements, blood loss, operative duration, hemodynamic intraoperative changes and diuresis, length of hospital stay, and creatinine values at days 1 and 2, and at discharge day. RESULTS: Total and warm ischemic time differed significantly between the two groups. Infusion of blood, fresh frozen plasma, colloid, and crystalloid did not significantly differ. Blood loss was lower, and intraoperative diuresis was not significantly increased in group A subjects. Postoperative hospitalizations were 16.5 and 17.8 days and operative times, 504 and 611 minutes in the two groups. Both cardiac index and ejection fraction values during the anhepatic phase were significantly greater among group A than group B patients. PAD at the two phases was greater in group B. The PAS was significantly different only at reperfusion time. Creatinine values were significantly different at discharge. Better survival was shown for group A patients over group B subjects. CONCLUSION: The results presented herein confirmed that a porto-caval shunt during OLT was a safe, useful expedient contributing to an improved hemodynamic status and a better time distribution in the various phases of liver transplantation.

Cetuximab/targeted chemotherapy in an HIV-positive patient with metastatic colorectal cancer in the HAART era: a case report.

Recent data have shown the efficacy of cetuximab/Folfiri regimen in patients with chemotherapy-resistant metastatic colorectal cancer. In the literature there are no data about this treatment in HIV-positive patients with metastatic colorectal cancer. At the Aviano Cancer Center, we used the cetuximab/Folfiri regimen and concomitant HAART in an HIV-positive patient with metastatic colorectal cancer. The patient experienced acceptable non-hematological toxicity, without any opportunistic infection and his HIV infection was kept under control. This case suggests that, in the HAART era, a multidisciplinary approach can be offered to HIV patients with advanced cancer when they have good performance status, resulting in efficacious control of the HIV infection.

Sirolimus monotherapy in liver transplantation.

INTRODUCTION: Since 1999, a new immunosuppressive drug was administered to renal transplant patients. The SRL molecule acts by blocking post-receptor signal transduction of interleukin-2 (IL-2) interacting with a family of intracellular binding proteins termed immunophilins FKBPs. Among these FKBPs, FK506 12-kd binding protein is the most relevant. SRL is an immunosuppressive drug. Therefore it can inhibit the immune system; at the same time the drug is not nephrotoxic, neurotoxic, and without diabetogenic effects. METHODS: Among 285 patients who underwent liver transplantation, 27 took Sirolimus as monotherapy. Immunosuppressive treatment upto cyclosporine (CsA) or tacrolimus (FK) associated with steroids (methylprednisolone) and mycophenolate Mofetil (MMF) was initiated among subjects with pre-transplant renal failure. SRL was administered as monotherapy for patients who developed nephrotoxicity, or neurotoxicity, or diabetes. Moreover, patients affected by multifocal HCC who did not meet the Milan criteria or patients who developed Kaposi's Sarcoma were prescribed SRL monotherapy. RESULTS: Nephrotoxicity occurred in 14 patients with mean serum creatinine level 2.2 mg/dl. Eleven patients with real failure showed significant improvements after a mean period of 28 days of SRL monotherapy (range: 6-45 days). The mean creatinine serum level after treatment with SRL monotherapy was 1.0 mg/dl (range: 0.7-1.2 mg/dl). Neurotoxicity occurred in 4 patients with tremor, confusion, and agitation. Each patient had complete improvement of symptoms after a few days of Sirolimus monotherapy. Among Three patients who developed Kaposi's Sarcoma, two underwent remission. One patient had diabetes due to calcineurin inhibitors, and one showed arterial hypertension not treatable with drugs. After the switch, we treated these patients with medications. Another important indication was HCC not meeting the Milan criteria. CONCLUSION: SRL monotherapy may be used to manage complication of calcineurin inhibitors or Kaposi's Sarcoma.

Adult-to-adult living donor liver transplantation using left lobes: the importance of surgical modulations on portal graft inflow.

BACKGROUND: Due to the shortage of available cadaveric organs, living donor liver transplantation (LDLT) has been recently applied extensively in adults. The use of the left lobe should be encouraged because of donor safety, but frequently the metabolic requirements of severely cirrhotic patients are great and subsequent graft dysfunction is encountered after transplantation. The importance of increased portal inflow to the graft in previously severely cirrhotic patients and other hemodynamic changes in LDLT using left lobes are still under debate, as are the surgical modulations to correct them. In this study, we have reported an initial series of adult-to-adult LDLT using left lobes, underlining the hemodynamic changes encountered during the transplant and the surgical modulations we applied to correct them. METHODS: Eight adult recipients underwent left lobe liver transplantation from living donors. Portal vein pressure and central venous pressure were measured before and after surgical modulation. RESULTS: We encountered four cases of small-for-size syndrome. Two patients were retransplanted; the other two died. Seventy-five percent of our recipients survived and 50% did not require further surgery. CONCLUSION: Surgical portal inflow modulation should be considered in cases of left lobe liver transplantation between adults.

Posttransplant Mycobacterium tuberculosis disease following liver transplantation and the need for cautious evaluation of Quantiferon TB GOLD results in the transplant setting: a case report.

This report describes a case of pulmonary tuberculosis in a liver transplant patient without a history of previous exposure to Mycobacterium tuberculosis (MTB) complex. Prior to transplantation, the tuberculin skin test was negative and the QuantiFERON-TB Gold (QFT Gold), an interferon gamma-based blood test, was negative before and after transplant including a period beginning on postoperative day 55 when the patient developed a febrile illness with an interstitial infiltrate and pleural effusion that was unresponsive to broad-spectrum antibiotic therapy. Empiric treatment with isoniazid, ethambutol, and levofloxacin resulted in resolution of the clinical symptoms. A sputum culture grew MTB on postoperative day 87. This case illustrates the need for caution when QFT Gold is used as diagnostic tool for latent tuberculosis during the pretransplant assessment. Further studies evaluating the usefulness of QFT Gold and other interferon gamma tests in posttransplantation active infection are warranted.

Hepatic hilum management in 250 liver-multivisceral procurements.

An accurate in vivo preparation of the hepatic hilum is a fundamental prerequisite for a successful multiorgan transplantation. Our preferred technique in this surgical setting is in vivo procurement in the heart-beating donor. This technique allows an effective exposition of the hilum structures and recognition of anatomical vascular variants, particularly those of the hepatic artery. Also, the cold ischemia time is drastically reduced, and the back-table preparation is left to a minimum. In this article we show the results of a consecutive series of 250 procurements.

Results of intestinal and multivisceral transplantation in adult patients: Italian experience.

PURPOSE: We report our experience with intestinal and multivisceral transplantation in Italy. METHODS: We performed 23 adult isolated intestinal transplants and seven multivisceral ones, three with liver, between December 2000 and June 2005. Indications for transplantation were loss of venous access (n = 14), recurrent sepsis (n = 10), and electrolyte-fluid imbalance (n = 6), 14 of whom also presented with total parenteral nutrition (TPN)-related liver dysfunction. Immunosuppression was based on induction agents like daclizumab (followed by tacrolimus and steroids) in the first period; alemtuzumab or thymoglobulin (with tacrolimus) in a second period after 2002. RESULTS: The mean follow-up was 742 +/- 550 days. Three-year patient actuarial survival rate was 88% for intestinal transplants and 42% for multivisceral (P = .015). Three-year graft actuarial survival rate was 73% for intestinal patients and 42.8% for multivisceral (P = .1). Graft loss was mainly due to rejection (57%). Complications were mainly represented by bacterial infections (92% of patients), relaparotomies (82%), and rejections (72%). Full bowel function without any parenteral nutrition or intravenous fluid support was achieved in 60% of recipients with functioning bowel including 95% on a regular diet. One patient underwent abdominal wall transplantation as well. DISCUSSION AND CONCLUSION: Intestinal transplantation has achieved high rates of patient and graft survival with even longer follow-up. Early referral of patients, especially in cases of TPN-liver disease, is mandatory to obtain good outcomes and avoid high mortality rates on the transplant waiting list. Immunosuppressive management remains the key factor to increase the success rate.

[Prognostic factors after surgical resection for hilar cholangiocarcinoma]. / Facteurs pronostiques après résection pour cholangiocarcinome hilaire.

AIMS: To evaluate short and long-term results in 23 patients resected for hilar cholangiocarcinoma. METHODS: Between January 2001 and December 2003, 23 patients with hilar cholangiocarcinoma were resected and considered for retrospective analysis. Univariate and multivariate analysis were performed on several clinicopathological variables in order to evaluate the short-term results. Median follow-up was 11 months (interquartile range 2-20 months). RESULTS: A major liver resection was performed in 19 out of 23 patients (82%): a right hepatectomy extended to segment 4 in 5 patients and a left hepatectomy in 14 patients. Resection of the caudate lobe was performed in 7 patients (30%). No hospital mortality occurred. Overall morbidity rate was 43%. The 1-year survival rate was 63.2% with a median survival of 19 months. Tumor recurrence appeared in 12 patients (52%). Low preoperative albumin level (P=0.006), presence of positive resection margin (P=0.03) and T-stage (P=0.02) were found to be related to a worse median survival. On multivariate analysis, only the preoperative albumin level and the presence of positive margin were confirmed as independent prognostic factors. CONCLUSION: Aggressive surgical approach remains the only potentially curative therapy for the hilar cholangiocarcinoma. Low preoperative albumin level, presence of positive resection margin and T-stage resulted as factors influencing the prognosis after resection.

Vacuum-Assisted Closure Therapy in Patients Undergoing Liver Transplantation With Necessity to Maintain Open Abdomen.

BACKGROUND: Negative-pressure wound therapy (NPWT) has been recognized as a valid method of temporary abdominal closure. The role of open abdomen (OA) in the management of abdominal sepsis has been a controversial issue. Recent experimental and clinical studies have indicated that vacuum-assisted closure (VAC) is associated with superior outcomes in the treatment of OA conditions, but sufficient proof of efficacy and effectiveness is lacking. METHODS: We enrolled in this observational study all patients who had undergone liver transplantation (LT) for all causes between 2007 and 2014 in whom we needed to use VAC therapy, describing the pathology that led to the complication, length of hospitalization, graft survival, microbial identifications, and causes of death. RESULTS: We enrolled 11 patients-6 men (55%) and 5 women (45%), from 41.92 to 64.96 years old (mean, 57.62 ± 6.56 years) -who went to LT for different pathologies. The mean hospital stay was 56.72 ± 36.40 days (range, 8-133 days). Graft survival was 35.65 ± 31.61 months (range, 1.51-89.19 months). Six of 11 patients died (55%) of different causes; in particular, 4 patients died 1 to 3 months after the procedures that led to the condition of OA for septic shock and subsequent multi-organ failure. CONCLUSIONS: Complications related to the use of NPWT, such as painful management and bleeding, are rare and mild when the device is used properly. Although studies are needed to verify the real cost/benefit ratio in this application of VAC therapy, we consider it a useful means to treat the OA condition.

Incidental Intra-Hepatic Cholangiocarcinoma and Hepatocholangiocarcinoma in Liver Transplantation: A Single-Center Experience.

BACKGROUND: Cholangiocarcinoma (CCA) is an aggressive malignancy of the biliary tract that is a challenging issue for the medical community, with increasing incidence. Risk factors for CCA are similar to those known for hepatocellular carcinoma (HCC), such as cirrhosis, chronic hepatitis B and C, obesity, diabetes, and alcohol. We describe the outcome and the management of patients who underwent liver transplantation (LT) with an incidental diagnosis of intrahepatic (iCCA) or hepatocholangiocarcinoma (CHC). METHODS: From 2000 to May 2015, 655 LT were performed LT at the Liver Transplant Center in Modena, Italy. We retrospectively reviewed the pathological data of the explanted livers, finding 5 cases of iCCA or CHC. The pathological examination of the explanted livers showed 1 case of iCCA; 1 case of multifocal HCC associated with a nodule of iCCA; 2 cases of CHC associated with nodules of HCC; and 1 case of CHC associated with iCCA. Mean disease-free survival (DFS) was 15.49 months (1.55-42.04) and mean overall survival (OS) was 24.76 months (3.91-75.49). All patients died of recurrent tumor progression. RESULTS: iCCA incidental finding after LT affects patient outcomes, massively causing OS and DFS reduction. We stress the necessity of a more accurate selection of the candidates whenever an augmented risk of iCCA or CHC is present. CONCLUSIONS: Further investigations are required to better understand the role of LT in these patients and to define the best management for them once they have been transplanted and the histological examination reveals the presence of iCCA or CHC.

Outcomes after adult isolated small bowel transplantation: experience from a single European centre.

BACKGROUND: Adult isolated small bowel transplantation is considered the standard treatment for patients with life-threatening parenteral nutrition-related complications. Here, we report a 3-year experience in a single European centre between December 2000 and December 2003. AIMS: To evaluate and discuss pre-transplant and post-transplant factors that influenced survival rates in our series. PATIENTS: Fourteen patients, with a mean parenteral nutrition course of 27 months, were transplanted. In eight cases they had not experienced any major complication from parenteral nutrition. METHODS: We described pre-transplant evaluation and inclusion criteria, surgical technique and clinical management after transplant. Immunosuppressive therapy was based on induction drugs and Tacrolimus. We reported survival rates, major complications and rejection events. RESULTS: One-year actuarial survival rate was of 92.3% with a mean 21-month follow-up (range 3-36 months). We had no intraoperative deaths. One patient (7.2%) died of sepsis following cytomegalovirus enteritis. One patient underwent graftectomy (7.2%) for intractable severe acute rejection. One-year actuarial graft survival rate of 85.1%. One patient (7.2%) affected by post-transplant lymphoproliferative disease is alive and disease-free after 8 months. CONCLUSION: We believe candidate selection, induction therapy, donor selection and short ischemia time play an important role in survival after small bowel transplantation.
