AIM: To investigate the impact of circadian rhythms on the outcomes of liver transplantation on patients suffering from hepatocellular carcinoma (HCC). METHODS: We retrospectively reviewed data of patients who underwent liver transplantation from 2012 to 2017 in our center. Based on the begin time of transplantation, these patients were separated into 2 groups: day group and night group. The intraoperative and postoperative clinical variables were analyzed to find out the impact of the circadian rhythms. Multivariate analysis was performed to examine strength associations between the begin time of operation and surgical outcomes. RESULTS: A total of 147 patients were included in this study: 102 patients in the day group and 45 patients in the night group. Compared with the day group, patients in the night group had higher incidence of intraoperative massive hemorrhage (11.1% vs 2.0%, P = .048), more intraoperative blood loss (2168.00 ± 2324.20 mL vs 1405.88 ± 1037.69 mL, P = .040), and more requirement of red blood cells (RBC) suspension (8.59 ± 7.11 u vs 6.37 ± 5.78 u, P = .048). In addition, total operation time in the night group was longer than that in the day group (8.90 ± 1.65 hours vs 8.26 ± 1.69 hours, P = .034), as well as the cold ischemia time (9.35 ± 5.03 hours vs 7.21 ± 3.93 hours, P = .014). Furthermore, the night group had higher incidence of other intraoperative complications (13.3% vs 2.9%, P = .038), postoperative abdominal infection (20.0% vs 6.9%, P = .038), and more hospital cost (37,357.96 ± 6779.96 dollars vs 33,551.75 ± 11,683.38 dollars, P = .045). Moreover, patients in the night group needed longer time to restore hepatic function to normal (21.77 ± 10.91 days vs 17.54 ± 10.80 days, P = .033). Multivariate analysis showed that begin time of operation was the independent risk factor of longer operation time, more blood loss during operation, higher incidence of massive hemorrhage and other intraoperative complications, longer time for restoration of hepatic function to normal, higher incidence of abdominal infection at the early stage after transplantation, and more hospital cost (all P value ≤ .05). CONCLUSION: Liver transplantation performed at night was associated with higher incidence of intraoperative and early postoperative complications, as well as higher hospital cost. And these worsened outcomes all could be explained by the influence that circadian rhythms had on patients or medical workers.

BACKGROUND: The adoption of laparoscopic techniques for living donor major hepatectomy has been controversial issue. The aim of this study is to present the preliminary experience of laparoscopic right hepatectomy in China. METHODS: All the donors receiving right hepatectomy for adult-to-adult living donor liver transplantation (LDLT) were divided into three groups: pure laparoscopic right hepatectomy (PLRH) group, hand-assisted right hepatectomy (HARH) group and open right hepatectomy (ORH) group. We compared the perioperative data and surgical outcomes of donors and recipients among three groups. RESULTS: From November 2001 to May 2017, 295 donors have received right hepatectomy for LDLT in our center. Among them, 7 donors received PLRH, 26 donors received HARH and 262 donors received ORH. The operation time of PLRH group (509.3 ± 98.9 min) was longer than that of the HARH group (451.6 ± 89.7 min) and the ORH group (418.4 ± 81.1 min, p = 0.003). The blood loss was the least in the PLRH group (378.6 ± 177.1 mL), compared with that in the HARH group (617.3 ± 240.4 mL) and that in the ORH group (798.6 ± 483.7 mL, p = 0.0013). The postoperative hospital stay was shorter in the PLRH group (7, 7-10 days) than that in the HATH group (8.5, 7.5-12 days) and ORH group (11, 9-14 days; p = 0.001). Only one donor had pleural effusion (Grade I) and another one experienced pulmonary infection (Grade II). One recipient (14.3%) in the PLRH group occurred hepatic venous stenosis. CONCLUSIONS: Laparoscopic approaches for right hepatectomy contribute to less blood loss, better cosmetic satisfaction, less severe complications, and faster rehabilitation. PLRH is a safe and feasible procedure, which must be performed in highly specialized centers with expertise of both LDLT and laparoscopic hepatectomy, and requires a hybrid-to-pure stepwise development.

There is little information regarding the predictive ability of albumin-bilirubin grades (ALBI) plus platelet-to-lymphocyte ratio (PLR) in patients with hepatocellular carcinoma (HCC) following liver resection. In this study, we aimed to evaluate the prognostic power of the ALBI-PLR score in patients with hepatitis B virus-related (HBV-related) HCC within Barcelona Clinic Liver Cancer (BCLC) stage A after liver resection.Around 475 patients were included in this study. Patients with preoperative ALBI grades 1, 2, or 3 were allocated a score of 0, 1, or 2, respectively. Patients with preoperative PLR >150 or ≤150 were allocated a score of 0 or 1, respectively. The ALBI-PLR score was the summary of the ALBI and PLR scores.During the follow-up period, 256 patients experienced recurrence, and 150 patients died. Multivariate analysis revealed tumor size, multiple tumors, positive HBV-DNA load, cirrhosis, and ALBI-PLR score as being independently associated with postoperative recurrence, whereas tumor size, high preoperative α-fetoprotein level, and ALBI-PLR score were independent risk factors for postoperative mortality. HCC patients with high ALBI-PLR score had poor recurrence-free and overall survival.The preoperative ALBI-PLR score is a surrogate marker for predicting HBV-related HCC patient's prognosis after liver resection. A high ALBI-PLR score is associated with a high incidence of postoperative recurrence and mortality.

OBJECTIVE: To assess the value of hepatic resection by comparing it with transarterial chemoembolization for hepatocellular carcinoma beyond the Milan criteria with clinically relevant portal hypertension. METHODS: A total of 363 patients and 193 propensity score-matched patients who had hepatocellular carcinoma beyond the Milan criteria with clinically relevant portal hypertension and underwent hepatic resection or transarterial chemoembolization were retrospectively analyzed. The short-term and long-term results were compared. RESULTS: Postoperative complications and 30-day mortality were similar between the two groups. The hepatic resection provided a survival benefit over TACE at 1, 2, 3, and 5 years. Similar results were observed in the propensity score analysis. Five variables were identified as independent prognostic factors: treatment, AFP, Child-Pugh classification, tumor number and extension of disease in a multivariate analysis of the whole study population. In addition, only the tumor number was identified as an independent risk factor after propensity matching. The subgroup analysis demonstrated that the survival benefit of the hepatic resection can only be derived in a subset of patients with a single tumor. CONCLUSIONS: In a properly selected group of patients with hepatocellular carcinoma beyond the Milan criteria with clinically relevant portal hypertension, hepatic resection appears to be as safe as TACE and provides a significant survival benefit.

BACKGROUND: There is currently limited information regarding the prognostic ability of the dNLR-PNI (the combination of the derived neutrophil-to-lymphocyte ratio [dNLR] and prognostic nutritional index [PNI]) for hepatocellular carcinoma (HCC). This study aimed to assess the predictive ability of the dNLR-PNI in patients with intermediate-to-advanced HCC after transarterial chemoembolization (TACE). METHODS: A total of 761 HCC patients were enrolled in the study. The dNLR-PNI was retrospectively calculated in these patients, as follows: patients with both an elevated dNLR and a decreased PNI, as determined using the cutoffs obtained from receiver operating characteristic curve analysis, were allocated a score of 2, while patients showing one or neither of these alterations were allocated a score of 1 or 0, respectively. RESULTS: During the follow-up period, 562 patients died. Multivariate analysis suggested that elevated total bilirubin, Barcelona Clinic Liver Cancer C stage, repeated TACE, and dNLR-PNI were independently associated with unsatisfactory overall survival. The median survival times of patients with a dNLR-PNI of 0, 1, and 2 were 31.0 (95% confidence interval [CI] 22.5-39.5), 16.0 (95% CI 12.2-19.7) and 6.0 (95% CI 4.8-7.2) months, respectively (P < 0.001). CONCLUSIONS: The dNLR-PNI can predict the survival outcomes of intermediate-to-advanced HCC patients undergoing TACE, and should be further evaluated as a prognostic marker for who are to undergo TACE treatment.

The aim of this study was to evaluate different surgical therapies for hepatic alveolar echinococcosis in different clinical stages.We analyze the clinical data of 115 patients who received surgical treatment in West China Hospital from January 2004 to June 2016. Among these patients, 77 cases underwent radical hepatic resection (group A, nâ=â77); 17 cases underwent palliative resection (group B, nâ=â17), and 21 cases underwent liver transplantation (group C, nâ=â21) with 12 cases of orthotopic liver transplantation and 9 cases of liver autotransplantation.The postoperative complication rate of radical hepatic resection group was 13.0% (10/77), which is statistically significant (Pâ<â.05) than the rate of palliative resection group 29.4% (5/17) or liver transplantation group 23.8% (5/21). The follow-up period ranged from 1 to 72 months. The overall median survival rate of radical resection was 72/77, higher than the rate of palliative group (12/17) or transplantation group (17/21), which was also statistically significant (Pâ<â.01).In our study, we believe in that all stages of hepatic alveolar echinococcosis should take active surgical interventions, and radical hepatic resection should be considered as the first-choice treatment for early stage of alveolar echinococcosis, while palliative surgery is still helpful to relieve symptoms and improve the life quality for advanced patients. Liver transplantation might also be an alternative option for the late-stage hepatic alveolar echinococcosis.

BACKGROUND/AIMS: To investigate the association between tacrolimus (TAC) blood concentration and the risk of post-transplantation diabetes mellitus (PTDM) development after living donor liver transplantation (LDLT). METHODS: This study reviewed the clinical data of 158 adult LDLT recipients. A cut-off of mean trough concentration of TAC (cTAC) value at the sixth month postoperatively was identified using a receptor operating characteristic curve. Other clinical complications rates were compared between different cTAC groups. RESULTS: Thirty-four (21.5%) recipients developed PTDM during follow-up period. Recipients with PTDM suffered lower 1-, 5- and 10-year overall survival rates (85.2%, 64.9%, and 55.6% vs 92.4%, 81.4%, and 79.1%, pâ¯<â¯0.05) and allograft survival rates (87.9%, 76.9%, and 65.9% vs 94.1%, 88.5%, and 86.0%, pâ¯<â¯0.05) than those without PTDM. The best cut-off value of mean cTAC was 5.9â¯ng/mL. Recipients with higher cTAC (>5.9â¯ng/mL) were more likely to develop hyperlipidemia (39.6% vs 21.9%, pâ¯<â¯0.05), cardio-cerebral events (7.5% vs1.0%, pâ¯<â¯0.05), and infections (37.7% vs19.0%, pâ¯<â¯0.05) than recipients exposed to low cTAC (≤5.9â¯ng/mL). However, the two groups showed no difference in the incidence of acute and chronic rejection. CONCLUSION: Higher mean cTAC at the sixth month postoperatively is related to increased risk of PTDM in LDLT recipients.

BACKGROUND: Given the shortage of suitable liver grafts for liver transplantation, proper use of hepatitis B core antibody-positive livers might be a possible way to enlarge the donor pool and to save patients with end-stage liver diseases. However, the safety of hepatitis B virus core antibody positive (HBcAb+) donors has been controversial. Initial studies were mainly conducted overseas with relatively small numbers of HBcAb+ liver recipients, and there are few relevant reports in the population of mainland China. We hypothesized that the safety of HBcAb+ liver grafts is not suboptimal. AIM: To evaluate the safety of using hepatitis B virus (HBV) core antibody-positive donors for liver transplantation in Chinese patients. METHODS: We conducted a retrospective study enrolling 1071 patients who underwent liver transplantation consecutively from 2005 to 2016 at West China Hospital Liver Transplantation Center. Given the imbalance in several baseline variables, propensity score matching was used, and the outcomes of all recipients were reviewed in this study. RESULTS: In the whole population, 230 patients received HBcAb+ and 841 patients received HBcAb negative (HBcAb-) liver grafts. The 1-, 3- and 5-year survival rates in patients and grafts between the two groups were similar (patient survival: 85.8% vs 87.2%, 77.4% vs 81.1%, 72.4% vs 76.7%, log-rank test, P = 0.16; graft survival: 83.2% vs 83.6%, 73.8% vs 75.9%, 70.8% vs 74.4%, log-rank test, P = 0.19). After propensity score matching, 210 pairs of patients were generated. The corresponding 1-, 3- and 5-year patient and graft survival rates showed no significant differences. Further studies illustrated that the post-transplant major complication rates and liver function recovery after surgery were also similar. In addition, multivariate regression analysis in the original cohort and propensity score-matched Cox analysis demonstrated that receiving HBcAb+ liver grafts was not a significant risk factor for long-term survival. These findings were consistent in both HBV surface antigen-positive (HBsAg+) and HBsAg negative (HBsAg-) patients.Newly diagnosed HBV infection had a relatively higher incidence in HBsAg- patients with HBcAb+ liver grafts (13.23%), in which HBV naive recipients suffered most (31.82%), although this difference did not affect patient and graft survival (P = 0.50 and P = 0.49, respectively). Recipients with a high HBV surface antibody (anti-HBs) titer (more than 100 IU/L) before transplantation and antiviral prophylaxis with nucleos(t)ide antiviral agents post-operation, such as nucleos(t)ide antiviral agents, had lower de novo HBV infection risks. CONCLUSION: HBcAb+ liver grafts do not affect the long-term outcome of the recipients. Combined with proper postoperative antiviral prophylaxis, utilization of HBcAb+ grafts is rational and feasible.

OBJECTIVE: Albumin-bilirubin (ALBI) grade has been validated as a simple, evidence-based, and objective prognostic tool for patients with hepatocellular carcinoma (HCC). However, minimal information is available concerning postoperative ALBI grade changes in HCC. This study aimed to investigate the prognostic value of postoperative ALBI grade changes in patients with hepatitis B virus (HBV)-related HCC within the Milan criteria after liver resection. METHODS: Patients with HBV-related HCC within the Milan criteria who underwent liver resection between 2010 and 2016 at West China Hospital were reviewed (N = 258). A change in ALBI grade was defined as first postoperative month ALBI grade-preoperative ALBI grade. If the value was >0, postoperative worsening of ALBI grade was considered; otherwise, stable ALBI grade was considered. Cox proportional hazard regression analyses were used to determine the factors that influence recurrence and survival. RESULTS: During the follow-up, 130 patients experienced recurrence and 47 patients died. Multivariate analyses revealed that postoperative worsening of ALBI grade (HR 1.541, 95% CI 1.025-2.318, P = 0.038), microvascular invasion (MVI, HR 1.802, 95% CI 1.205-2.695, P = 0.004), and multiple tumors (HR 1.676, 95% CI 1.075-2.615, P = 0.023) were associated with postoperative recurrence, whereas MVI (HR 2.737, 95% CI 1.475-5.080, P = 0.001), postoperative worsening of ALBI grade (HR 2.268, 95% CI 1.227-4.189, P = 0.009), high alpha-fetoprotein level (HR 2.055, 95% CI 1.136-3.716, P = 0.017), and transfusion (HR 2.597, 95% CI 1.395-4.834, P = 0.003) negatively influenced long-term survival. Patients with postoperative worsening of ALBI grade exhibited increased incidence of recurrence and worse long-term survival. CONCLUSION: Postoperative worsening of ALBI grade was associated with increased recurrence and poorer overall survival for patients with HBV-related HCC within the Milan criteria. We should pay attention to liver function changes in HCC patients after liver resection.

BACKGROUND: There is little information concerning futile liver resection for patients with Barcelona Clinic Liver Cancer (BCLC) stage B/C hepatocellular carcinoma (HCC). This study aimed to establish a predictive model of futile liver resection for patients with BCLC stage B/C HCC. METHODS: The outcomes of 484 patients with BCLC stage B/C HCC who underwent liver resection at our centre between 2010 and 2016 were reviewed. Patients were randomised and divided 2:1 into training and validation sets. A novel risk-scoring model and prognostic nomogram were developed based on the results of multivariate analysis. RESULTS: Fifty-seven futile operations were observed. Multivariate analyses revealed tumour numbers > 3, Vp4 portal vein tumour thrombosis (PVTT) and alpha-fetoprotein (AFP) > 400 ng/ml independently associated with futile liver resection. A risk-scoring model based on the above-mentioned factors was developed (predictive risk score = 1 × (if AFP > 400 ng/ml) + 2 × (if tumour number > 3) + 3 × (if with Vp4 PVTT)). The area under the receiver-operating characteristic curve of this model was 0.845, with a sensitivity of 60.0% and a specificity of 94.8%. A prognostic nomogram was also developed and achieved a C-index of 0.831. The validation studies optically supported these results. CONCLUSION: A risk-scoring model and predictive nomogram for futile liver resection were developed in the present study. T`he BCLC stage B/C HCC patients with a high risk obtained no benefit from liver resection.

Here, we report a case of severe immune thrombocytopenia that occurred after orthotopic liver transplant. On day 16 after transplant, the patient was readmitted to our hospital with a platelet count of 0 cells/mL, with the count remaining at a low level of 1000 to 10 000 cells/mL for 46 days. A diagnosis was made, after exclusion of other causes, of thrombocytopenia. Platelet blood transfusion and high-dose prednisone (1mg/kg/d) combined with intravenous immunoglobulin (0.5g/kg/d) were administered with no improvement. After additional treatments, which included altered use of immunosuppressive agents, changing adefovir to lamivudine and continuous steroid therapy, the patient was discharged with a platelet count of 55 000 cells/mL. Both liver and renal functions generally stayed well during hospitalization. The patient was discharged uneventfully and achieved remission during 10-month follow-up after discharge.

OBJECTIVE: To investigate the postoperative hemodynamics changes and their influence factors in the donors after right lobe living donor liver transplantation. METHODS: A total of 53 consecutive living donors from Dec 2010 to Aug 2015 who underwent donor right lobe hepatectomy were retrospectively analyzed. We measured residual liver hemodynamics with color doppler ultrasound, detected liver stiffness by transient elastography, also analyzed postoperative liver function, hemodynamics, and the long term variation tendency of hepatocirrhosis and spleen. RESULTS: One week after operation, transient liver damage was observed. Post-operative hemodynamics within the follow-up time showed:portal vein diameter was gradually increasing, the velocity decreased gradually;Hepatic vein diameter increased, and the velocity decreased gradually. There was a negative correlation between portal vein diameter and portal vein velocity (P=0.012, r=-3.11). Liver stiffness (Kpa value) decreased gradually with time, while spleen volume gradually increased. Correlation analysis showed that postoperative liver stiffness (Kpa value) was negatively related to portal vein diameter (P=0.013, r=-0.338) and positively related to hepatic venous velocity (P=0.038,r=0.246). CONCLUSIONS: The donor presented a transient liver injury after operation, but tended to be recovery after one week. Despite post-operative hemodynamic undergo a series of changes, but it does not affect the post-operative long-term donor safety.
RESUMO
The aim of this study was to compare the outcomes of patients with multiple hepatocellular carcinoma (HCCs) after liver resection (LR) versus liver transplantation (LT). Patients who had multiple HCCs without macrovascular invasion and who underwent LT or LR between 2007 and 2013 were reviewed. A propensity score matching model was used to adjust baseline differences between the two groups. A total of 204 patients were selected for the current study, including 137 LR patients and 67 LT patients. During follow-up, 100 patients experienced recurrence, and 78 patients died. The 5-year recurrence-free survival rate was 71.1% for the LT group and 31.1% for the LR group (P<0.001). The 5-year overall survival rate was 73.4% for the LT group and 39.8% for the LR group (P<0.001). Moreover, the LT group had better recurrence-free survival and overall survival rates than the LR group regardless of whether the patients met or exceeded the Milan criteria. The multivariate analysis showed that microvascular invasion and LR were independent risk factors for postoperative recurrence, whereas only LR was associated with an increased incidence of mortality. After applying one-to-one propensity score matching, similar results were observed in the propensity score matching model. Our study suggested that LT provided a better prognosis for patients with multiple HCCs than LR regardless of whether the patients met the Milan criteria.
RESUMO
The neutrophil-to-lymphocyte ratio (NLR) reflects the systematic inflammatory status, and the aspartate aminotransferase-to-alanine aminotransferase ratio (AAR) is a biomarker of liver fibrosis and cirrhosis. These values can be conveniently obtained from routine blood tests; however, their combined clinical utility has not been extensively studied in patients with hepatocellular carcinoma (HCC) undergoing transarterial chemoembolization (TACE). This study aimed to investigate the prognostic value of NLR-AAR in patients with unresectable HCC undergoing TACE. Data for 760 patients with newly diagnosed HCC were retrospectively evaluated. The NLR-AAR was calculated as follows: patients in whom both the NLR and AAR were elevated according to the receiver operating characteristic (ROC) curve analysis were assigned a score of 2; patients showing an elevation in one or neither of these indicators were assigned a score of 1 or 0, respectively. Univariate and multivariate analyses were performed to identify the clinicopathological variables associated with overall survival. An ROC curve was also generated and the area under the curve (AUC) was calculated to evaluate the discriminatory ability of each index at 1, 3, and 5 years of follow-up, as well as overall. The NLR-AAR consistently had a greater AUC value at 1 year (0.669), 3 years (0.667), and 5 years (0.671) post-TACE compared with either NLR or AAR alone. The median survival times of patients with a NLR-AAR of 0, 1, and 2 were 31.0 (95% confidence interval [CI] 24.0-38.0), 15.0 (95% CI 11.2-18.8), and 5.0 (95% CI 4.0-5.9) months, respectively (Pâ<â.001). Multivariate analysis showed that the NLR-AAR, elevated total bilirubin level, and vascular invasion were independently associated with overall survival. NLR and AAR, when combined to produce an inflammation-based index and fibrosis score, is an independent marker of poor prognosis in patients with HCC receiving TACE.

For many malignancies, inflammation-based scores correlate with survival. The neutrophil-to-lymphocyte ratio (NLR) and prognostic nutritional index (PNI) are immunonutritional indices associated with postoperative outcomes in patients with hepatocellular carcinoma (HCC). We evaluated whether a combined preoperative NLR and PNI score was prognostically superior to either index alone in 793 patients with unresectable HCC after transarterial chemoembolization. Patient demographic, clinical, and pathological data were also collected and analysed. A receiver-operating characteristic (ROC) analysis was used to classify patients as follows: NLR-PNI 0 group (NLR ≤ 2.2 and PNI > 46), NLR-PNI 1 group (NLR > 2.2 or PNI ≤ 46) and NLR-PNI 2 group (NLR > 2.2 and PNI ≤ 46). Regarding 1-, 3-, and 5-year survival, the NLR-PNI score had superior discriminative abilities (i.e., higher area under the ROC curve), compared with either the NLR or PNI alone, and patients in the NLR-PNI 0, 1, and 2 groups had median survival times of 33 (95% confidence interval: 22.8-43.2), 14 (10.9-17.1), and 6 (9.9-14.1) months, respectively. In multivariate analyses, the Barcelona Clinic Liver Cancer, total bilirubin, vascular invasion, and NLR-PNI score adversely affected overall survival. In conclusion, the NLR-PNI score can improve the accuracy of prognoses for patients with unresectable HCC.

OBJECTIVE/AIM: The aim of this study was to identify a new index to predict early allograft dysfunction following living donor liver transplantation. METHODS: The study enrolled 260 adult living donor liver transplantation recipients. Postoperative laboratory variables were assessed for their association with the prevalence of early allograft dysfunction using the inverse probability of treatment weighting and propensity-score matching (n=93 pairs) analysis. RESULTS: Forty-seven recipients (18.1%) developed early allograft dysfunction. In multivariable analysis, the alanine aminotransferase and gamma-glutamyl transpeptidase levels on postoperative day 1 were independent predictors of early allograft dysfunction. The alanine aminotransferase to gamma-glutamyl transpeptidase ratio (AGR) was developed. All cases were divided into two groups (Group 1 [AGR≥8.47, n=103] and Group 2 [AGR<8.47, n=157]). AGR≥8.47 (OR 10.345, 95%CI 4.502-23.772, p<0.001), hepatorenal syndrome (OR 3.016, 95%CI 1.119-8.125, p=0.029), and graft to recipient weight ratio <0.8% (OR 2.155, 95%CI 1.004-4.624, p=0.049) were independent risk factors for early allograft dysfunction. The prevalence of early allograft dysfunction was higher in group 1 (after adjusting for inverse probability of treatment weighting [n=39; 37.9% vs n=8; 5.1%] and propensity-score matching [n=33; 35.5% vs n=2; 2.2%]) than that in group 2 (p<0.001). CONCLUSIONS: The postoperative AGR is a practical index for predicting early allograft dysfunction after living donor liver transplantation.

BACKGROUND: Many studies have confirmed that serum total cholesterol (sTC) concentrations were associated with underlying liver damage and the synthesis capacity of liver. However, the role of postoperative sTC level on evaluating graft function and predicting survival of recipients who underwent liver transplantation has not been discussed. METHODS: Clinical data of 231 living donor liver transplantation recipients from May 2003 to January 2015 were retrospectively collected. Patients were stratified into the low sTC group (sTC <1.42 mmol/L, 57 recipients) and high sTC group (sTC =1.42 mmol/L, 174 recipients) according the sTC level on postoperative day 3 based on receiver-operating characteristic curve analysis. The clinical characteristics and postoperative short- and long-term outcomes were compared between the two groups. RESULTS: Recipients with sTC <1.42 mmol/L experienced more severe preoperative disease conditions, a higher incidence of postoperative early allograft dysfunction (38.6% vs 10.3%, P<0.001), 90-day mortality (28.1% vs 10.9%, P=0.002) and severe complications (29.8% vs 17.2%, P=0.041) compared to recipients with sTC =1.42 mmol/L. The multivariate analysis demonstrated that sTC <1.42 mmol/L had a 4.08-fold (95% CI: 1.83-9.11, P=0.001) and 2.72-fold (95% CI: 1.23-6.00, P=0.013) greater risk of developing allograft dysfunction and 90-day mortality, and patients with sTC <1.42 mmol/L had poorer overall recipient and graft survival rates at 1-, 3-, and 5-year than those with sTC =1.42 mmol/L (67%, 61% and 61% vs 83%, 71% and 69%, P=0.025; 65%, 59% and 59% vs 81%, 68% and 66%, P=0.026, respectively). Cox multivariate analysis showed that sTC <1.42 mmol/L was an independent predicting factor for total recipient survival (HR=2.043; 95% CI: 1.173-3.560; P=0.012) and graft survival (HR=1.905; 95% CI: 1.115-3.255; P=0.018). CONCLUSIONS: sTC <1.42 mmol/L on postoperative day 3 was an independent risk factor of postoperative early allograft dysfunction, 90-day mortality, recipient and graft survival, which can be used as a marker for predicting postoperative short- and long-term outcomes.

BACKGROUND: Combined hepatectomy and radiofrequency ablation (RFA) provides an additional treatment for patients with Barcelona Clinic Liver Cancer (BCLC) stage B hepatocellular carcinoma (HCC) who are conventionally deemed unresectable. This study aimed to analyze the outcome of this combination therapy by comparing it with transarterial chemoembolization (TACE). METHODS: We retrospectively reviewed 51 patients with unresectable BCLC stage B HCC who had received the combination therapy. We compared the survival of these patients with that of 102 patients in the TACE group (control). Prognostic factors associated with worse survival in the combination group were analyzed. RESULTS: No differences in tumor status and liver function were observed between the TACE group and combination group. The median survival time for the combination group and TACE group was 38 (6-54) and 17 (3-48) months, respectively (P<0.001). The combination group required longer hospitalization than the TACE group [8 (5-14) days vs 4 (2-9) days, P<0.001]. More than two ablations decreased the survival rate in the combination group. CONCLUSIONS: Combined hepatectomy and RFA yielded a better long-term outcome than TACE in patients with unresectable BCLC stage B HCC. Patients with a limited ablated size (≤2 cm), a limited number of ablations (≤2), and adequate surgical margin should be considered candidates for combination therapy.

AIM: To investigate the impact of minimum tacrolimus (TAC) on new-onset diabetes mellitus (NODM) after liver transplantation (LT). METHODS: We retrospectively analyzed the data of 973 liver transplant recipients between March 1999 and September 2014 in West China Hospital Liver Transplantation Center. Following the exclusion of ineligible recipients, 528 recipients with a TAC-dominant regimen were included in our study. We calculated and determined the mean trough concentration of TAC (cTAC) in the year of diabetes diagnosis in NODM recipients or in the last year of the follow-up in non-NODM recipients. A cutoff of mean cTAC value for predicting NODM 6 mo after LT was identified using a receptor operating characteristic curve. TAC-related complications after LT was evaluated by χ(2) test, and the overall and allograft survival was evaluated using the Kaplan-Meier method. Risk factors for NODM after LT were examined by univariate and multivariate Cox regression. RESULTS: Of the 528 transplant recipients, 131 (24.8%) developed NODM after 6 mo after LT, and the cumulative incidence of NODM progressively increased. The mean cTAC of NODM group recipients was significantly higher than that of recipients in the non-NODM group (7.66 ± 3.41 ng/mL vs 4.47 ± 2.22 ng/mL, P < 0.05). Furthermore, NODM group recipients had lower 1-, 5-, 10-year overall survival rates (86.7%, 71.3%, and 61.1% vs 94.7%, 86.1%, and 83.7%, P < 0.05) and allograft survival rates (92.8%, 84.6%, and 75.7% vs 96.1%, 91%, and 86.1%, P < 0.05) than the others. The best cutoff of mean cTAC for predicting NODM was 5.89 ng/mL after 6 mo after LT. Multivariate analysis showed that old age at the time of LT (> 50 years), hypertension pre-LT, and high mean cTAC (≥ 5.89 ng/mL) after 6 mo after LT were independent risk factors for developing NODM. Concurrently, recipients with a low cTAC (< 5.89 ng/mL) were less likely to become obese (21.3% vs 30.2%, P < 0.05) or to develop dyslipidemia (27.5% vs 44.8%, P <0.05), chronic kidney dysfunction (14.6% vs 22.7%, P < 0.05), and moderate to severe infection (24.7% vs 33.1%, P < 0.05) after LT than recipients in the high mean cTAC group. However, the two groups showed no significant difference in the incidence of acute and chronic rejection, hypertension, cardiovascular events and new-onset malignancy. CONCLUSION: A minimal TAC regimen can decrease the risk of long-term NODM after LT. Maintaining a cTAC value below 5.89 ng/mL after LT is safe and beneficial.
