Experience with solid organ transplantation in patients with previous immunotherapy treatment is still limited but this is changing: The survey-based view of the global transplant society.

BACKGROUND: The use of immunotherapy for cancer is increasing and is expected to continue growing. The outcomes after solid organ transplantation(SOT) in patients who received immunotherapy before SOT remain unclear. We evaluated the global transplant surgery community's attitude towards and experience with patients who received immunotherapy for malignancy before SOT. METHODS: An online-based survey was sent to North American transplant program directors in December-2020 and members of the International Liver Transplant Society in November-2021 evaluating experiences with and attitudes towards SOT in recipients with previous immunotherapy for cancer. RESULTS: A total of 119 respondents completed the survey(119/175;completion rate:68%), representing centers from North America, South America, Europe, Asia, and Australia. Seventy-one(62%) respondents would consider SOT in patients with a previous history of immunotherapy for cancer, whereas thirty-nine(34%) were aware of such immunotherapy-treated recipients being transplanted, with an increasing trend over the last few years(2016[n = 1]-2020[n = 14]). Institutional clinical management policies in this setting were lacking in most centers(n = 85[75%]). CONCLUSIONS: The international transplant community is receptive to transplanting transplant candidates previously treated with immunotherapy for cancer, although experience is still limited. In this context, more centers have started to offer SOT to patients with a history of immunotherapy for cancer in recent years. However, support from clear and robust institutional policies in this endeavor is scant. Therefore, there is a high need for consensus guidelines to inform future clinical management, especially as immunotherapy for cancer is likely to continue to increase in the coming years.

Long-term outcomes of ablation, liver resection, and liver transplant as first-line treatment for solitary HCC of 3 cm or less using an intention-to-treat analysis: A retrospective cohort study.

Background: Curative-intent therapies for hepatocellular carcinoma (HCC) include radiofrequency ablation (RFA), liver resection (LR), and liver transplantation (LT). Controversy exists in treatment selection for early-stage tumours. We sought to evaluate the oncologic outcomes of patients who received either RFA, LR, or LT as first-line treatment for solitary HCC ≤ 3 cm in an intention-to-treat analysis. Materials and methods: All patients with solitary HCC ≤ 3 cm who underwent RFA, LR, or were listed for LT between Feb-2000 and Nov-2018 were analyzed. Cox regression analysis was then performed to compare intention-to-treat (ITT) survival by initial treatment allocation and disease-free survival (DFS) by treatment received in patients eligible for all three treatments. Results: A total of 119 patients were identified (RFA n = 83; LR n = 25; LT n = 11). The overall intention-to-treat survival was similar between the three groups. The overall DFS was highest for the LT group. This was significantly higher than RFA (p = 0.02), but not statistically significantly different from LR (p = 0.14). After multivariable adjustment, ITT survival was similar in the LR and LT groups relative to RFA (LR HR:1.13, 95%CI 0.33-3.82; p = 0.80; LT HR:1.39, 95%CI 0.35-5.44; p = 0.60). On multivariable DFS analysis, only LT was better relative to RFA (LR HR:0.52, 95%CI 0.26-1.02; p = 0.06; LT HR:0.15, 95%CI 0.03-0.67; p = 0.01). Compared to LR, LT was associated with a numerically lower hazard on multivariable DFS analysis, though this did not reach statistical significance (HR 0.30, 95%CI 0.06-1.43; p = 0.13). Conclusion: For treatment-naïve patients with solitary HCC ≤ 3 cm who are eligible for RFA, LR, and LT, adjusted ITT survival is equivalent amongst the treatment modalities, however, DFS is better with LR and LT, compared with RFA. Differences in recurrence between treatment modalities and equipoise in ITT survival provides support for a future prospective trial in this setting.

Regional Therapies for Colorectal Liver Metastases: Systematic Review and Clinical Practice Guideline.

BACKGROUND: Resection is the foundation for cure for colorectal cancer (CRC) liver metastases; however, only 20% of patients are suitable for surgery. Those suitable would be considered for resection or local therapies before being considered for regional therapies. Noncurative treatment is usually systemic chemotherapy. For patients with liver-only or liver-predominant metastases that are unresectable, regional therapies [conventional transarterial chemoembolization (cTACE), drug-eluting bead transarterial chemoembolization (DEB-TACE), and transarterial radioembolization (TARE)] may be considered. We review the current evidence for regional therapies for CRC liver metastases. PATIENTS AND METHODS: Literature searches (January 2000 to March 2019 or January 2010 to March 2019 depending on the specific systematic review question) were conducted, including Medline, Embase, Cochrane Library, and 2018 American Society of Clinical Oncology (ASCO) abstracts. RESULTS: A total of 4100 articles were identified; 15 studies were included in the review. There were no comparative data regarding the resectable population. There was either insufficient evidence (cTACE or DEB-TACE) or evidence against (TARE) the addition of regional therapies to systemic therapy in the first line in the unresectable population. There was either no evidence (cTACE) or weak evidence (DEB-TACE or TARE) for the addition of regional therapies with or without systemic therapy in the second line or later in the unresectable population. CONCLUSION: Limited evidence supports the delivery of percutaneous regional therapies in patients with unresectable CRC liver metastases. There are strong data demonstrating positive effects of TARE within the liver, but they do not translate to a benefit in patient-important outcomes. DEB-TACE appears to offer a survival benefit in the second-line setting, although the evidence is limited by small sample size and larger trials are needed.

Predictors of outcome after liver transplantation for hepatocellular carcinoma (HCC) beyond Milan criteria.

The Milan criteria have been the cornerstone of selection policies for patients with hepatocellular carcinoma (HCC) awaiting liver transplantation (LT) globally for over two decades. Many groups have proposed the transplantation of patients with larger and more numerous tumors achieving comparable results. Many of these use radiologic morphometric criteria as surrogates for explant pathology to predict outcomes. Several other indices have been developed both within and beyond Milan incorporating biological indices as well as dynamic markers of response to pre-transplant locoregional treatments and waiting time. These have allowed for successful expansion of transplant selection criteria without compromising outcomes with limited organ supplies. In this review we will discuss the predictors of outcome in patients beyond Milan criteria.

Liver transplantation outcomes after transarterial chemotherapy for hepatocellular carcinoma.

BACKGROUND: Transarterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC) awaiting liver transplantation is widespread, although evidence that it improves outcomes is lacking and there exist concerns about morbidity. The impact of TACE on outcomes after transplantation was evaluated in this study. METHODS: Patients with HCC who had liver transplantation in the UK were identified, and stratified according to whether they received TACE between 2006 and 2016. Cox regression methods were used to estimate hazard ratios (HRs) for death and graft failure after transplantation adjusted for donor and recipient characteristics. RESULTS: In total, 385 of 968 patients (39·8 per cent) received TACE. Five-year patient survival after transplantation was similar in those who had or had not received TACE: 75·2 (95 per cent c.i. 68·8 to 80·5) and 75·0 (70·5 to 78·8) per cent respectively. After adjustment for donor and recipient characteristics, there were no differences in mortality (HR 0·96, 95 per cent c.i. 0·67 to 1·38; P = 0·821) or graft failure (HR 1·01, 0·73 to 1·40; P = 0·964). The number of TACE treatments (2 or more versus 1: HR 0·97, 0·61 to 1·55; P = 0·903) or the time of death after transplantation (within or after 90 days; P = 0·291) did not alter the outcome. The incidence of hepatic artery thrombosis was low in those who had or had not received TACE (1·3 and 2·4 per cent respectively; P = 0·235). CONCLUSION: TACE delivered to patients with HCC before liver transplant did not affect complications, patient death or graft failure after transplantation.

ANTECEDENTES: La quimioembolización transarterial (transarterial chemoembolization, TACE) en pacientes con carcinoma hepatocelular (hepatocellular carcinoma, HCC) se utiliza como puente al trasplante hepático, aunque falta evidencia de que mejore los resultados y la morbilidad relacionada es motivo de preocupación. En este estudio se evaluó el impacto de la TACE en los resultados tras el trasplante para analizar las complicaciones. MÉTODOS: Se identificaron los receptores de trasplante hepático por HCC en el Reino Unido y se estratificaron según si habían recibido TACE entre 2006 y 2016. Se utilizó el método de regresión de Cox para estimar los cocientes de riesgos instantáneos (hazard ratio, HR) para la mortalidad post-trasplante y el fallo del injerto ajustados por las características del donante y del receptor. RESULTADOS: En total, 385 (39,8%) de 968 pacientes recibieron TACE, observándose similar supervivencia del paciente a los 5 años después del trasplante: 75,2% (i.c. del 95%: 68,8% a 80,5%) con TACE y 75,0% (70,5% a 78,8 %) sin TACE. Después de ajustar según las características del donante y del receptor, no hubo diferencias en la mortalidad (HR: 0,96, 0,67 a 1,38; P = 0,82) o en el fallo del injerto (HR: 1,01, 0,73 a 1,40; P = 0,96). El número de tratamientos con TACE (≥ 2 tratamientos TACE HR: 0,97, 0,61 a 1,55; P = 0,90) o el período de tiempo después del trasplante (mortalidad del paciente antes o después de 90 días; P = 0,29) no alteró el resultado. La incidencia de trombosis de la arteria hepática fue baja en aquellos que recibieron TACE o no (1,3% y 2,5%, respectivamente; P = 0,23). El fallo del injerto debido a eventos oclusivos fue similar en el grupo de pacientes que recibieron TACE (8,0% o 11/137) o que no la recibieron (6,7% o 5/75) TACE (P = 0,74). CONCLUSIÓN: La administración de TACE en pacientes con HCC antes del trasplante hepático no influyó en las complicaciones post-trasplante, la mortalidad del paciente o el fallo del injerto.

Combined lung-liver-pancreas transplantation in a recipient with cystic fibrosis.

Cystic fibrosis (CF) affects multiple organs including the lung, liver, and pancreas. Lung transplant, liver transplant, and combined lung-liver transplant have become well-established therapies for CF patients with end-stage organ failure. Thus far, however, there has been limited experience with pancreas transplantation in CF. In this report, we detail the clinical history, transplant procedure, and post-operative recovery of a patient who underwent combined lung-liver-pancreas transplant for advanced CF.

Liver transplantation for "very early" intrahepatic cholangiocarcinoma: International retrospective study supporting a prospective assessment.

UNLABELLED: The presence of an intrahepatic cholangiocarcinoma (iCCA) in a cirrhotic liver is a contraindication for liver transplantation in most centers worldwide. Recent investigations have shown that "very early" iCCA (single tumors ≤2 cm) may have acceptable results after liver transplantation. This study further evaluates this finding in a larger international multicenter cohort. The study group was composed of those patients who were transplanted for hepatocellular carcinoma or decompensated cirrhosis and found to have an iCCA at explant pathology. Patients were divided into those with "very early" iCCA and those with "advanced" disease (single tumor >2 cm or multifocal disease). Between January 2000 and December 2013, 81 patients were found to have an iCCA at explant; 33 had separate nodules of iCCA and hepatocellular carcinoma, and 48 had only iCCA (study group). Within the study group, 15/48 (31%) constituted the "very early" iCCA group and 33/48 (69%) the "advanced" group. There were no significant differences between groups in preoperative characteristics. At explant, the median size of the largest tumor was larger in the "advanced" group (3.1 [2.5-4.4] versus 1.6 [1.5-1.8]). After a median follow-up of 35 (13.5-76.4) months, the 1-year, 3-year, and 5-year cumulative risks of recurrence were, respectively, 7%, 18%, and 18% in the very early iCCA group versus 30%, 47%, and 61% in the advanced iCCA group, P = 0.01. The 1-year, 3-year, and 5-year actuarial survival rates were, respectively, 93%, 84%, and 65% in the very early iCCA group versus 79%, 50%, and 45% in the advanced iCCA group, P = 0.02. CONCLUSION: Patients with cirrhosis and very early iCCA may become candidates for liver transplantation; a prospective multicenter clinical trial is needed to further confirm these results.

Acute Antibody-Mediated Rejection as Cause of Late Liver Allograft Failure: A Case Report.

BACKGROUND: Despite now being an infrequent complication in liver transplantation (LT) recipients, acute liver failure is still associated with high mortality. CASE REPORT: Here we report a case of acute liver failure 11 months after AB0-compatible LT in a hepatitis C-positive 50-year-old male recipient caused by late antibody-mediated rejection (AMR). De novo donor-specific antibodies appeared later in a previously negative donor-recipient crossmatch, leading to a rapid deterioration of liver function. CONCLUSIONS: We highlight the importance of an accurate diagnosis and an early therapeutic intervention. The analysis of this case brings novel and generalizable insights to the differential diagnosis of acute liver failure after LT.

Analysis of adult 20-year survivors after liver transplantation.

BACKGROUND: Liver transplantation (LT) is the treatment of choice for chronic and acute liver failure; however, the status of long-term survivors and allograft function is not well known. AIM: To evaluate the clinical outcome and allograft function of survivors 20 years post-LT, cause of death during the same period and risk factors of mortality. METHODS: A retrospective study was conducted from prospective, longitudinal data collected at a single center of adult LT recipients surviving 20 years. A comparative sub-analysis was made with patients who were not alive 20 years post-transplantation to identify the causes of death and risk factors of mortality. RESULTS: Between 1988 and 1994, 132 patients received 151 deceased-donors LT and 28 (21%) survived more than 20 years. Regarding liver function in this group, medians of AST, ALT and total bilirubin at 20 years post-LT were 33 IU/L (13-135 IU/L), 27 (11-152 IU/L) and 0.6 mg/dL (0.3-1.1 mg/dL). Renal dysfunction was observed in 40% of patients and median eGFR among 20-year survivors was 64 mL/min/1.73 m(2) (6-144 mL/min/1.73 m(2)). Sixty-one percent of 20-year survivors had arterial hypertension, 43% dyslipidemia, 25% de novo tumors and 21% diabetes mellitus. Infections were the main cause of death during the 1st year post-transplant (32%) and between the 1st and 5th year post-transplant (25%). After 5th year from transplant, hepatitis C recurrence (22%) became the first cause of death. Factors having an impact on long-term patient survival were HCC indication (p = 0.049), pre-transplant renal dysfunction (p = 0.043) and long warm ischemia time (p = 0.016); furthermore, post-transplant factors were diabetes mellitus (p = 0.001) and liver dysfunction (p = 0.05) at 1 year. CONCLUSION: Our results showed the effect of immunosuppression used during decades on long-term outcome in our LT patients in terms of morbidity (arterial hypertension, diabetes mellitus, dyslipidemia and renal dysfunction) and mortality (infections and hepatitis C recurrence).

Benefit of Treating Hepatocellular Carcinoma Recurrence after Liver Transplantation and Analysis of Prognostic Factors for Survival in a Large Euro-American Series.

PURPOSE: To identify prognostic factors after hepatocellular carcinoma (HCC) recurrence after liver transplantation (LT). METHODS: We retrospectively reviewed the combined experience at Toronto General Hospital and Hospital Vall d'Hebron managing HCC recurrence after LT (n = 121) between 2000 and 2012. We analyzed prognostic factors by uni- and multi-variate analysis. Median follow-up from LT was 29.5 (range 2-129.4) months. Median follow-up from HCC recurrence was 12.2 (range 0.1-112.5) months. RESULTS: At recurrence, 31.4 % were treated with curative-intent treatments (surgery or ablation), 42.1 % received palliative treatment, and 26.4 % received best supportive care. The 1-, 3-, and 5-year survivals, respectively, after HCC recurrence were 75, 60, and 31 %, vs. 60, 19, and 12 %, vs. 52, 4, and 5 % (p < 0.001). By multivariate analysis, not being amenable to a curative-intent treatment [hazard ratio (HR) 4.7, 95 % confidence interval (CI) 2.7-8.3, p < 0.001], α-fetoprotein of ≥100 ng/mL at the time of HCC recurrence (HR 2.1, 95 % CI 1.3-2.3, p = 0.002) and early recurrence (<12 months) after LT (HR 1.6, 95 % CI 1.1-2.5, p = 0.03) were found to be poor prognosis factors. A prognostic score was devised on the basis of these three independent variables. Patients were divided into three groups, as follows: good prognosis, 0 points (n = 22); moderate prognosis, 1 or 2 points (n = 84); and poor prognosis, 3 points (n = 15). The 1-, 3-, and 5-year actuarial survival for each group was 91, 50, and 50 %, vs. 52, 7, and 2 %, vs. 13, 0, and 0 %, respectively (p < 0.001). CONCLUSIONS: Patients with HCC recurrence after transplant amenable to curative-intent treatments can experience significant long-term survival (~50 % at 5 years), so aggressive management should be offered. Poor prognosis factors after recurrence are not being amenable to a curative-intent treatment, α-fetoprotein of ≥100 ng/mL, and early (<1 year) recurrence after LT.

Immunosuppression based on everolimus in liver transplant recipients with severe early post-transplantation neurotoxicity.

The immunosuppressive management of liver transplant recipients suffering early calcineurin inhibitor-induced neurotoxicity is a challenge in daily clinical practice. We have assessed the use of everolimus as the main immunosuppressant in patients presenting severe neurotoxicity in the early post-transplantation period. From October 1988 to October 2012, 10 patients in our center received everolimus because of severe neurotoxicity in the 1st 3 months after transplantation. We analyzed several variables associated with this treatment, including patient characteristics, time from liver transplantation to conversion to everolimus, immunosuppression regimens before and after conversion, treatment efficacy, adverse events, and discontinuation after conversion. Median follow-up after conversion to everolimus was 27 months (range, 1-63 mo). Neurotoxic events were: akinetic mutism in 4 patients, repeated convulsions in 3, cerebrovascular accident in 1, Guillain-Barré syndrome in 1, and disabling tremor in 1. Treatment with calcineurin inhibitors was discontinued in all patients. Post-conversion regimens consisted of everolimus plus mycophenolate mofetil (MMF) plus steroids in 7 patients, everolimus plus MMF in 1, everolimus plus steroids in 1, and everolimus alone in 1. Liver function was maintained for ≥1 month in all patients except 1, who presented a severe rejection that was treated with steroid bolus and Neoral cyclosporine. Neurologic function was fully recovered in 8 patients. In 1 patient with akinetic mutism and another with convulsions, tacrolimus was reintroduced at 2 months and 1 month, respectively, after resolution of the neurotoxic event. Everolimus is feasible and effective as the main immunosuppressant in patients suffering severe neurotoxicity during the 1st 3 months after transplantation. It allows neurologic function to be recovered while maintaining adequate liver function.

"Very early" intrahepatic cholangiocarcinoma in cirrhotic patients: should liver transplantation be reconsidered in these patients?

A retrospective cohort multicenter study was conducted to analyze the risk factors for tumor recurrence after liver transplantation (LT) in cirrhotic patients found to have an intrahepatic cholangiocarcinoma (iCCA) on pathology examination. We also aimed to ascertain whether there existed a subgroup of patients with single tumors ≤2 cm ("very early") in which results after LT can be acceptable. Twenty-nine patients comprised the study group, eight of whom had a "very early" iCCA (four of them incidentals). The risk of tumor recurrence was significantly associated with larger tumor size as well as larger tumor volume, microscopic vascular invasion and poor degree of differentiation. None of the patients in the "very early" iCCA subgroup presented tumor recurrence compared to 36.4% of those with single tumors >2 cm or multinodular tumors, p = 0.02. The 1-, 3- and 5-year actuarial survival of those in the "very early" iCCA subgroup was 100%, 73% and 73%, respectively. The present is the first multicenter attempt to ascertain the risk factors for tumor recurrence in cirrhotic patients found to have an iCCA on pathology examination. Cirrhotic patients with iCCA ≤2 cm achieved excellent 5-year survival, and validation of these findings by other groups may change the current exclusion of such patients from transplant programs.

Intrahepatic cholangiocarcinoma or mixed hepatocellular-cholangiocarcinoma in patients undergoing liver transplantation: a Spanish matched cohort multicenter study.

OBJECTIVE: To evaluate the outcome of patients with hepatocellular-cholangiocarcinoma (HCC-CC) or intrahepatic cholangiocarcinoma (I-CC) on pathological examination after liver transplantation for HCC. BACKGROUND: Information on the outcome of cirrhotic patients undergoing a transplant for HCC and with a diagnosis of HCC-CC or I-CC by pathological study is limited. METHODS: Multicenter, retrospective, matched cohort 1:2 study. STUDY GROUP: 42 patients undergoing a transplant for HCC and with a diagnosis of HCC-CC or I-CC by pathological study; and control group: 84 patients with a diagnosis of HCC. I-CC subgroup: 27 patients compared with 54 controls; HCC-CC subgroup: 15 patients compared with 30 controls. Patients were also divided according to the preoperative tumor size and number: uninodular tumors 2 cm or smaller and multinodular or uninodular tumors 2 cm or larger. Median follow-up: 51 (range, 3-142) months. RESULTS: The 1-, 3-, and 5-year actuarial survival rate differed between the study and control groups (83%, 70%, and 60% vs 99%, 94%, and 89%, respectively; P < 0.001). Differences were found in 1-, 3-, and 5-year actuarial survival rates between the I-CC subgroup and their controls (78%, 66%, and 51% vs 100%, 98%, and 93%; P < 0.001), but no differences were observed between the HCC-CC subgroup and their controls (93%, 78%, and 78% vs 97%, 86%, and 86%; P = 0.9). Patients with uninodular tumors 2 cm or smaller in the study and control groups had similar 1-, 3-, and 5-year survival rate (92%, 83%, 62% vs 100%, 80%, 80%; P = 0.4). In contrast, patients in the study group with multinodular or uninodular tumors larger than 2 cm had worse 1-, 3-, and 5-year survival rates than their controls (80%, 66%, and 61% vs 99%, 96%, and 90%; P < 0.001). CONCLUSIONS: Patients with HCC-CC have similar survival to patients undergoing a transplant for HCC. Preoperative diagnosis of HCC-CC should not prompt the exclusion of these patients from transplant option.

Liver resection and transplantation offer similar 5-year survival for Child-Pugh-Turcotte A HCC-patients with a single nodule up to 5 cm: a multicenter, exploratory analysis.

BACKGROUND AND AIM: The current guideline of the American Association for the Study of Liver Diseases recommends liver resection for Child-Pugh-Turcotte A patients with a single hepatocellular carcinoma, total serum bilirubin ≤ 1 mg/dL and absence of significant portal hypertension. This subset of patients would have a long-term survival comparable to transplantation. The main aim of this study is to evaluate the survival rates in patients with a single nodule ≤ 5 cm following resection. METHODS: Medical records of 105 Child-Pugh-Turcotte A patients who underwent liver resection between 1997 and 2009 were analyzed in 3 countries. RESULTS: One, 3-, and 5-year survival rate was 97%, 83%, and 66%, respectively, and no variable that can be assessed prior to liver resection predicted survival probabilities. CONCLUSIONS: Liver resection offers 5-year survival similar to transplantation for Child-Pugh-Turcotte A patients with hepatocellular carcinoma and a single nodule up to 5 cm, independently of any patient baseline characteristics.

Evolution of biliary complications after liver transplantation: a single European series.

BACKGROUND: The aim of this study was to analyze the evolution of biliary complications over 20 years among adult patients undergoing liver transplantation (OLT) at our institution. PATIENTS AND METHODS: Between 1985 and 2007, we performed 1000 OLT in 789 adults and 211 children. To ascertain the evolution of biliary complications among adult OLT from October 1988 to September 2007, we compared the first 100 to with the last 200 adult OLT. RESULTS: Duct-to-duct was the most common biliary anastomosis performed in both periods (1st; 89% and 2nd; 94%; P = NS). However, a T-tube was used more frequently in the first period (1st; 46% vs 2nd; 6.6%; P < .001). The remaining cases underwent a hepaticojejunostomy (1st; 11% vs 2nd; 7.6%). Biliary complications were more frequent in the first period (1st; 20% vs 2nd; 9%; P < .01). In the first period, the use of a T-tube caused 32% of complications, all of them being bile leaks; but there were none in the second period. Arterial thrombosis or strictures were related to biliary complications in 10% and 33.3% among the first and second periods, respectively. The severity of complications according to the Clavien classification was similar in both periods: IIIa, 15% versus 33.3%; IIIb, 55% versus 55.5%; and IV, 15% versus 11.1%, respectively (P = NS). CONCLUSION: The biliary complication rate among adult patients post-OLT decreased over 20 years at our institution, probably owing to the abandonment of the routine use of a T-tube as well as to advances in immunosuppressive protocols, organ preservation, and preoperative patient management.

Indications and management of everolimus after liver transplantation.

OBJECTIVE: Our aim was to assess our experience with the use and management of everolimus after orthotopic liver transplantation (OLT). MATERIALS AND METHODS: Among the 759 patients who underwent transplantation from 1988 to 2008, 25 (3.2%) received immunosuppression with everolimus. Their mean age was 55.6 years. We analyzed indications for use, time between transplantation and introduction of everolimus, as well as its efficacy, side effects, and patient survival. RESULTS: The indications for everolimus treatment were: extended hepatocellular carcinoma (HCC) in the explanted liver (n = 6; 24%); HCC recurrence during follow-up (n = 4; 16%); de novo tumor (n = 6; 24%); refractory rejection (n = 3; 12%); side effects of calcineurin inhibitors (CNI; n = 3; 12%); and other causes (n = 3; 12%). Mean time between OLT and everolimus treatment was 40 +/- 33 months (range, 10 days-178 months). Mean follow-up after conversion was 10 +/- 9 months (range, 1.5-25 months). More than half of the patients resolved the event for which the drug was indicated: 75% of patients with refractory rejection; 60% of those with renal insufficiency; and 100% of those converted for neurotoxicity or hepatotoxicity. Two patients with recurrent HCC and 1 with extended HCC died at a mean time of 10.5 months. The 6 cases of de novo tumors were operated and are healthy. Side effects were dyslipidemia in 8 and infection in 2. Five patients (20%) discontinued the drug. CONCLUSIONS: In the early posttransplantation period, everolimus is indicated for refractory rejection or as prophylaxis for recurrence of extended tumors. In any time but especially in the late period, everolimus is indicated for patients with serious side effects due to a CNI or to a de novo tumor.

Severe rhabdomyolysis and acute renal failure secondary to concomitant use of simvastatin with rapamycin plus tacrolimus in liver transplant patient.

OBJECTIVE: To report a severe interaction between simvastatin and rapamycin resulting in rhabdomyolysis and acute renal failure in a liver transplant patient. BACKGROUND: A 56-year-old man with hepatitis C virus cirrhosis (Child B) was diagnosed with hepatocellular carcinoma and underwent liver transplantation in April 2007. He was immunosuppressed with tacrolimus (FK) and mycophenolate mofetil (MMF). Postoperative complications were arterial hypertension and renal insufficiency. In June 2007, liver dysfunction was detected and acute rejection was diagnosed by biopsy. He received three 500-mg boluses of methylprednisolone and FK levels were maintained between 10 and 12 ng/mL. Laboratory values revealed persistent rejection and MMF was stopped with initiation of rapamicin. One month later, hyperlipidemia appeared as a consequence of rapamicin therapy; simvastatin was administered. In August 2007, the patient was readmitted due to severe muscule pain and the inability to ambulate. Laboratory values were: total bilirubin 16 mg/dL, serum creatinine 4.3 mg/dL, and total creatine kinase (CK) 42,124 U/L. With the suspicion of rhabdomyolysis, leading to worsening of his basal renal insufficiency, rapamycin and tacrolimus were stopped. Hemodialysis was initiated owing to renal failure and hyperkalemia. Some hours later, the patient developed ventricular fibrillation and respiratory failure and succumbed. DISCUSSION: Calcineurin inhibitors (CNI), corticosteroids, and mammalian target of rapamycin (m-TOR) inhibitors are associated with adverse dyslipidemic effects. To reduce the overall cardiovascular risk in these patients, lipid-lowering drugs, especially 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, have been widely used. CNI and m-TOR inhibitors, as well as most statins, are metabolized by cytochrome P450 (CYP)3A4; thus, pharmacokinetic interactions between these drugs are possible. Previous reports have indicated an increased risk of rhabdomyolysis in the presence of concomitant drugs that inhibit simvastatin metabolism. CONCLUSIONS: Concomitant administration of statin therapy and drugs that inhibit cytochrome P450 (CYP)3A4 increased the risk of rhabdomyolysis in a patient suffering liver and renal dysfunction.

Recurrence of hepatocellular carcinoma after liver transplantation.

Outcome after liver transplantation (OLT) clearly depends on recurrence of hepatocellular carcinoma (HCC). After recurrence, patient outcome will depend on the time and site of appearance. The aim of this study was to analyze the therapeutic implications of tumor recurrence behavior. From October 1988 to December 2005, 685 patients received OLT, including 202 due to HCC (32%). We analyzed 28 recurrences (15.2%) among 184 patients who survived at least 3 months (minimum follow-up 1 year). According to the time of recurrence, we divided the patients into early recurrence (ER < 12 months; n = 9; 32.1%) and late recurrence (LR > 12 months n = 19; 67.9%). Actuarial survivals at 1, 5, and 10 years were 82%, 65%, and 50% and disease-free survival, 80%, 58%, and 46%, respectively. Risk factors for recurrence were: vascular invasion (P < .01), bad differentiation (P < .01), and previous hepatectomy (P < .05). After OLT, ER presented at: 5.7 +/- 2.3 months (range 3-10) vs 33.5 +/- 24.3 months (range 12-103) for LR P < .001). Survival postrecurrence (SPR) was shorter: 3.1 +/- 2.4 (range 1-8) months vs 16.4 +/- 14.2 (range 1-5) months (P < .001). Treatment was offered to one ER (11%) and to eight LR (47.1%; P < .05), achieving in these cases longer SPR: 20.1 +/- 14 vs 6.9 +/- 9 months (P < .05). The most common sites of recurrence were liver (n = 7), lung (n = 7), bone (n = 5), adrenal gland (n = 2), peritoneum (n = 2), lymph node (n = 2), skin (n = 2) or cerebral (n = 1). Early recurrences showed short survivals; no treatment could be offered to these patients. Liver recurrence appeared early. In contrast, most lung recurrences appeared later with the possibility of treatment and longer SPR. Bone recurrence appeared later, usually associated with other locations. Treatment was palliative and prognosis was worse. Skin and lymph node recurrences can be treated curatively with prolonged survival. In conclusion, HCC recurrence was difficult to treat curatively and was only prevented by employing restricted criteria.

'My heart belongs to daddy'. Some reflections on the difference between generations as the organiser of the triangular structure of the mind.

The author begins his paper with a historical review of the concept of the difference between generations, which is in his opinion a metaphorical transformation that underpins the three-dimensional functioning of the psychic apparatus by introducing a differentiating intergenerational space between subject and object. He postulates that at the point of intersection between the intersubjective and the intrapsychic the subject clings to the specific fragments of his parents' history that are consistent with a belief about himself and the oedipal couple in which intergenerational links are severed and infantile incestuous wishes are seen as fulfilled. Disavowal of this generation gap is considered to lead to failure of post-oedipal secondary identifications, resulting in disturbance of the triangular structuring of the mind and consequent impairment of the genesis of thought processes. These ideas are compared with related conceptions of other authors and illustrated, with an account of the associated transference/countertransference vicissitudes, by a clinical example of the constellation the author calls 'My heart belongs to daddy', which he sees as a way station in the negotiation of the female Oedipus complex.
