Prognostic nomograms for HBV-related BCLC 0-a stage hepatocellular carcinoma incorporating aspartate aminotransferase to albumin ratio.

BACKGROUND: Curative hepatectomy is currently the first-line treatment for hepatocellular carcinoma (HCC), but the prognosis is still not optimistic. The prediction model for prognosis of hepatitis B virus (HBV)-related BCLC 0-A stage HCC has not been well established. Therefore, we aimed to develop new nomograms to predict recurrence and survival in these patients. METHODS: A total of 982 patients with HBV-related BCLC 0-A stage HCC who underwent curative hepatectomy at West China Hospital from February 2007 to February 2016 were retrospectively collected and randomly allocated to a training set and a validation set in a ratio of 4:1. Prognostic nomograms using data from the training set were developed using a Cox regression model and validated on the validation set. RESULTS: We constructed nomograms based on independent factors for recurrence-free survival (RFS) (tumor size, satellite, microvascular invasion, capsular invasion, differentiation and aspartate aminotransferase to albumin ratio (ASAR)) and overall survival (OS) (gender, tumor size, satellite, microvascular invasion, differentiation, lymphocyte count, and ASAR). Compared with conventional HCC staging systems and other nomograms reported by previous literature, our ASAR integrated nomograms predicted RFS and OS with the highest C-indexes (0.682 (95%CI: 0.646-0.709), 0.729 (95%CI: 0.691-0.766), respectively) and had well-fitted calibration curves in the training set. Concurrently, the nomograms also obtained consistent results in the validation set. DCA revealed that our nomograms provided the largest clinical net benefits. CONCLUSION: We first constructed ASAR integrated nomograms to predict the prognosis of HBV-related BCLC 0-A stage HCC patients after curative hepatectomy with good performance.

Tumor burden score-AFP-albumin-bilirubin grade score predicts the survival of patients with hepatocellular carcinoma after liver resection.

PURPOSE: There is little information regarding the overall survival (OS) predictive ability of the combination of tumor burden score (TBS), α-fetoprotein (AFP), and albumin-bilirubin (ALBI) grade for patients with hepatocellular carcinoma (HCC). Here, we aimed to develop a model including TBS, AFP, and ALBI grade to predict HCC patient OS following liver resection. METHODS: Patients (N = 1556) from six centers were randomly divided 1:1 into training and validation sets. The X-Tile software was used to determine the optimal cutoff values. The time-dependent area under the receiver operating characteristic curve (AUROC) was calculated to assess the prognostic ability of the different models. RESULTS: In the training set, tumor differentiation, TBS, AFP, ALBI grade, and Barcelona Clinic Liver Cancer (BCLC) stage were independently related to OS. According to the coefficient values of TBS, AFP, and ALBI grade, we developed the TBS-AFP-ALBI (TAA) score using a simplified point system (0, 2 for low/high TBS, 0, 1 for low/high AFP and 0,1 for ALBI grade 1/2). Patients were further divided into low TAA (TAA ≤ 1), medium TAA (TAA = 2-3), and high TAA (TAA= 4) groups. TAA scores (low: referent; medium, HR = 1.994, 95% CI = 1.492-2.666; high, HR = 2.413, 95% CI = 1.630-3.573) were independently associated with patient survival in the validation set. The TAA scores showed higher AUROCs than BCLC stage for the prediction of 1-, 3-, and 5-year OS in both the training and validation sets. CONCLUSION: TAA is a simple score that has better OS prediction performance than the BCLC stage in predicting OS for HCC patients after liver resection.

Hazard rate for postoperative recurrence in patients with hepatocellular carcinoma at Barcelona Clinic Liver Cancer stage 0 or A1: A multicenter observational study.

AIM: Surgical treatment is the first-line treatment for patients with Barcelona Clinic Liver Cancer (BCLC) stage 0 or A1 hepatocellular carcinoma (HCC), and postoperative monitoring improves long-term survival. We aimed to establish a reasonable short-interval follow-up duration for patients with HCC. METHODS: The cohort for this retrospective study included 1396 HCC patients with BCLC stage 0 or A1 disease who underwent curative resection from 2013 to 2016 at five centers in China. Hazard rates for recurrence were calculated using the hazard function. RESULTS: The recurrence rates in patients with BCLC stage 0 and A1 HCC were 46.4% and 58.0%, respectively. The hazard curve for stage 0 patients was relatively flat, and the hazard rate was consistently low (peak hazard rate 0.0163). The hazard rate curve for recurrence was initially high (peak hazard rate 0.0441) in patients with BCLC stage A1 disease and showed a rapid decreasing trend within 1 year, followed by a slow decreasing trend, reaching a low level (<0.0163) at approximately 36 months. The time to low risk was 47, 41, and 51 months in patients with cirrhosis, hepatitis B virus (HBV) infection, and satellite lesions, respectively. CONCLUSIONS: A short-interval follow-up of 1 year is sufficient for HCC patients with BCLC stage 0 disease, whereas a short-interval follow-up time of 3 years should be considered for patients with stage A1 disease. The follow-up period should be appropriately prolonged for patients with cirrhosis, HBV infection, and satellite lesions.

An Eastern Hepatobiliary Surgery Hospital/Portal Vein Tumor Thrombus Scoring System as an Aid to Decision Making on Hepatectomy for Hepatocellular Carcinoma Patients With Portal Vein Tumor Thrombus: A Multicenter Study.

Portal vein tumor thrombus (PVTT) is a significant poor prognostic factor for hepatocellular carcinoma (HCC). Patients with PVTT limited to a first-order branch of the main portal vein (MPV) or above could benefit from negative margin (R0) liver resection (LR). An Eastern Hepatobiliary Surgery Hospital (EHBH)/PVTT scoring system was established to predict the prognosis of HCC patients with PVTT after R0 LR and guide selection of subgroups of patients that could benefit from LR. HCC patients with PVTT limited to a first-order branch of the MPV or above who underwent R0 LR as an initial therapy were included. The EHBH-PVTT score was developed from a retrospective cohort in the training cohort using a Cox regression model and validated in a prospective internal validation cohort and three external validation cohorts. There were 432 patients in the training cohort, 285 in the prospective internal validation cohort, and 286, 189, and 135 in three external validation cohorts, respectively. The score was calculated using total bilirubin, α-fetoprotein (AFP), tumor diameter, and satellite lesions. The EHBH-PVTT score differentiated two groups of patients (≤/>3 points) with distinct long-term prognoses (median overall survival [OS], 17.0 vs. 7.9 months; P < 0.001). Predictive accuracy, as determined by the area under the time-dependent receiver operating characteristic curves (AUCs; 0.680-0.721), was greater than that of the other commonly used staging systems for HCC and PVTT. Conclusion: The EHBH-PVTT scoring system was more accurate in predicting the prognosis of HCC patients with PVTT than other staging systems after LR. It selected appropriate HCC patients with PVTT limited to a first-order branch of the MPV or above for LR. It can be used to supplement the other HCC staging systems.

An Eastern Hepatobiliary Surgery Hospital Microvascular Invasion Scoring System in Predicting Prognosis of Patients with Hepatocellular Carcinoma and Microvascular Invasion After R0 Liver Resection: A Large-Scale, Multicenter Study.

BACKGROUND: Microvascular invasion (MVI) is associated with poor postoperative survival outcomes in patients with hepatocellular carcinoma (HCC). An Eastern Hepatobiliary Surgery Hospital (EHBH) MVI scoring system was established to predict prognosis in patients with HCC with MVI after R0 liver resection (LR) and to supplement the most commonly used classification systems. MATERIALS AND METHODS: Patients with HCC with MVI who underwent R0 LR as an initial therapy were included. The EHBH-MVI score was developed from a retrospective cohort from 2003 to 2009 to form the training cohort. The variables associated with overall survival (OS) on univariate analysis were subsequently investigated using the log-rank test, and the EHBH-MVI score was developed using the Cox regression model. It was validated using an internal prospective cohort from 2011 to 2013 as well as three independent external validation cohorts. RESULTS: There were 1,033 patients in the training cohort; 322 patients in the prospective internal validation cohort; and 493, 282, and 149 patients in the three external validation cohorts, respectively. The score was developed using the following factors: α-fetoprotein level, tumor encapsulation, tumor diameter, hepatitis B e antigen positivity, hepatitis B virus DNA load, tumor number, and gastric fundal/esophageal varicosity. The score differentiated two groups of patients (≤4, >4 points) with distinct long-term prognoses outcomes (median OS, 55.8 vs. 19.6 months; p < .001). The predictive accuracy of the score was greater than the other four commonly used staging systems for HCC. CONCLUSION: The EHBH-MVI scoring system was more accurate in predicting prognosis in patients with HCC with MVI after R0 LR than the other four commonly used staging systems. The score can be used to supplement these systems. IMPLICATIONS FOR PRACTICE: Microvascular invasion (MVI) is a major determinant of survival outcomes after curative liver resection for patients with hepatocellular carcinoma (HCC). Currently, there is no scoring system aiming to predict prognosis of patients with HCC and MVI after R0 liver resection (LR). Most of the widely used staging systems for HCC do not use MVI as an independent risk factor, and they cannot be used to predict the prognosis of patients with HCC and MVI after surgery. In this study, a new Eastern Hepatobiliary Surgery Hospital (EHBH) MVI scoring system was established to predict prognosis of patients with HCC and MVI after R0 LR. Based on the results of this study, postoperative adjuvant therapy may be recommended for patients with HCC and MVI with an EHBH-MVI score >4. This score can be used to supplement the currently used HCC classifications to predict postoperative survival outcomes in patients with HCC and MVI.

A novel combined systemic inflammation-based score can predict survival of intermediate-to-advanced hepatocellular carcinoma patients undergoing transarterial chemoembolization.

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.

Pure laparoscopic right hepatectomy of living donor is feasible and safe: a preliminary comparative study in China.

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.

Postoperative Albumin-Bilirubin Grade Change Predicts the Prognosis of Patients with Hepatitis B-Related Hepatocellular Carcinoma Within the Milan Criteria.

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.

Alpha fetoprotein changes predict hepatocellular carcinoma survival beyond the Milan criteria after hepatectomy.

BACKGROUND: Assessing the outcomes of surgeries for hepatocellular carcinoma (HCC) patients who exceed the Milan criteria is necessary. Some studies have demonstrated that preoperative or postoperative alpha fetoprotein (AFP) can predict HCC patients' prognoses. METHODS: A total of 280 HCC patients who were positive for AFP and received curative resection were retrospectively analyzed. The patients were classified into three groups according to their preoperative and postoperative AFP levels (group A: normalized AFP; group B: AFP decreases >50%, but continued abnormality; and group C: AFP decreases <50%). Disease-free survival and overall survival rates were analyzed using the Kaplan-Meier method. The factors associated with AFP changes were evaluated by logistic regression. RESULTS: AFP dynamic changes were independently associated with disease-free survival and overall survival rates. Group A had better 3- and 5-y survivals than groups B or C (58.7% and 39.5% versus 31.3% and 14.9% versus 17.1% and 8.8%, P < 0.001). Preoperative AFP, tumor differentiation, tumor diameter, microvascular invasion, and satellite nodules remained significant risk factors that were associated with AFP changes. Furthermore, in group A, the disappearances of AFP within and beyond 8 wk resulted in similar overall survival rates (P > 0.05). Among those with HCC recurrence, the patients treated with resurgery or radiofrequency ablation achieved the best recurrence to death survivals. Those treated with transcatheter arterial chemoembolization achieved the next best survivals. CONCLUSIONS: AFP changes predicted the prognoses of patients with HCC beyond the predictions of the Milan criteria. Preoperative AFP (>400 ng/mL), tumor differentiation, tumor diameter, and satellite nodules were the risk factors related to AFP normalization. The regular follow-up and early detection of recurrent HCCs that are suitable for curative therapies, such as resurgery and radiofrequency ablation, might improve the prognoses. Other therapies, such as transcatheter arterial chemoembolization, might also be effective.

Liver resection versus liver resection plus TACE for patients with hepatocellular carcinoma beyond Milan criteria.

BACKGROUND: The recurrence of patients with hepatocellular carcinoma (HCC) beyond the Milan criteria after liver resection (LR) is common. This study aimed to clarify whether LR plus postoperative adjuvant transcatheter arterial chemoembolization (TACE) could improve the outcomes of patients with HCC beyond the Milan criteria after LR. METHODS: A total of 754 consecutive patients with HCC beyond the Milan criteria who received LR alone (n = 459) or LR + TACE (n = 295) were included. A propensity scoring matched model (PSM) was used to adjust for the baseline differences between the groups. RESULTS: The 1, 3, and 5-y recurrence-free survival (76.7%, 40.4%, and 30.8%, respectively, for the LR-alone group versus 78.3%, 50.5%, and 46.2%, respectively, for the LR + TACE group; P = 0.004) and overall survival (94.1%, 58.3%, and 36.3%, respectively, for the LR-alone group versus 95.3%, 71.3%, and 54.9%, respectively, for the LR + TACE group; P < 0.001) rates of patients who underwent LR alone were much lower than in the LR + TACE group. Multivariate Cox proportional hazards regression analysis showed that LR alone was an independent risk factor for postoperative recurrence and poor long-term survival. After one-to-one PSM, 284 patients who underwent LR alone and 284 patients who underwent LR + TACE were selected for further analyses. Similar results were observed in the PSM model. CONCLUSIONS: This study showed that LR + TACE may be beneficial for patients with HCC beyond the Milan criteria. Postoperative adjuvant TACE should be considered to patients with HCC beyond the Milan criteria.

Role of the postoperative cholesterol in early allograft dysfunction and survival 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.

Microvascular invasion patterns affect survival in hepatocellular carcinoma patients after second hepatectomy.

BACKGROUND: Microvascular invasion (MVI) is an important risk factor for survival of patients with hepatocellular carcinoma (HCC) after hepatectomy. However, its impact on patients with recurrent HCC who receive a second hepatectomy is unknown. METHODS: We enrolled 167 patients with HCC who underwent a second hepatectomy because of intrahepatic recurrences. We compared the patients' demographic, tumor, and pathologic characteristics with 766 cases of original hepatectomy. We analyzed the possible risk factors for survival after the first and second hepatectomies and the influence of different MVI patterns on patients' survival after the second hepatectomy. RESULTS: The median overall survival was comparable between the first and second hepatectomy groups, 34 (3-84) mo versus 27 (3-57) mo, P = 0.09. For patients who underwent a first hepatectomy, the presence of macro-VI or MVI, an early recurrence pattern, and a total tumor diameter >5 cm were independent risk factors. For survival after the second hepatectomy, MVI patterns that were positive-positive or negative-positive and a total recurrent tumor diameter >5 cm were significant risk factors for survival. CONCLUSIONS: A second hepatectomy provides satisfying survival for patients with intrahepatic recurrence of HCC after the initial operation. Different MVI patterns affect survival after the second hepatectomy. Because MVI represents the biological behavior of HCC, we place a high premium on the clinical value of MVI after each hepatectomy.

Hepatic Arterial Buffer Response Maintains the Homeostasis of Graft Hemodynamics in Patient Receiving Living Donor Liver Transplantation.

BACKGROUND: In living donor liver transplantation (LDLT), the hepatic hemodynamics plays important roles in graft regeneration, and the hepatic blood inflows are associated with graft size. However, the data of interplay between the hepatic arterial buffer response (HABR) and graft-to-recipient weight ratio (GRWR) in clinical LDLT are lacking. AIMS: To identify the effect of the HABR on the hepatic hemodynamics and recovery of graft function and to evaluate the safe lower limit of the GRWR in carefully selected recipients. METHODS: Portal venous and hepatic arterial blood flow was measured in recipients with ultrasonography, and the graft functional recovery, various complications, and survive states after LDLT were compared. RESULTS: In total, 246 consecutive patients underwent LDLT with right lobe grafts. In total, 26 had a GRWR < 0.7 % (A), 29 had a GRWR between 0.7 and 0.8 % (B), and 181 had a GRWR > 0.8 % (C). For small-for-size syndrome, there was no significant difference (P = 0.176). Graft survival rates at 1, 3, and 5 year were not different (P = 0.710). The portal vein flow and portal vein flow per 100 g graft weight peaks were significantly higher in the A. Hepatic arterial velocity and hepatic arterial flow decreased in all the three groups on postoperative day 1; however, the hepatic arterial flow per 100 g graft weight was close to healthy controls. CONCLUSIONS: HABR played important roles not only in the homeostasis of hepatic afferent blood supply but also in maintaining enough hepatic perfusion to the graft.

Combined hepatectomy and radiofrequency ablation versus TACE in improving survival of patients with unresectable BCLC stage B HCC.

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.

Prognostic value of the platelet to lymphocyte ratio change in liver cancer.

BACKGROUND: There is limited evidence concerning the postoperative platelet to lymphocyte ratio change (ΔPLR) in relation to the prognosis of hepatocellular carcinoma (HCC). This study was designed to evaluate the prognostic value of ΔPLR in patients with hepatitis B virus (HBV)-related small HCC who underwent liver resection. MATERIALS AND METHODS: We retrospectively reviewed 219 patients with HBV-related small HCC who underwent liver resection between February 2007 and April 2013. The patients were divided into two groups as follows: group A (ΔPLR ≥2.875, n = 94) and group B (ΔPLR <2.875, n = 125), according to receiver operating characteristic analysis. Demographic, clinical, and follow-up data were analyzed, and multivariate analysis was used to identify prognostic factors. RESULTS: The 1-, 3-, and 5-y overall survival (OS) rates were 90.5%, 72.3%, and 42.1%, respectively, in group A and 98.1%, 89.5%, and 86.4%, respectively, in group B (P < 0.001). Correspondingly, the 1-, 3-, and 5-y recurrence-free survival (RFS) rates were 57.5%, 36.1%, and 22.8%, respectively, in group A and 84.3%, 62.4%, and 55.4%, respectively, in group B (P < 0.001). Multivariate analysis showed that ΔPLR was an independent prognostic factor for both OS (P < 0.001, hazard ratio = 5.452, 95% confidence interval 2.592-11.467) and RFS (P < 0.001, hazard ratio = 2.191, 95% confidence interval 1.4611-3.288). CONCLUSIONS: ΔPLR was an independent prognostic factor for OS and RFS in patients with HBV-related small HCC who underwent liver resection.

Postoperative neutrophil-to-lymphocyte ratio plus platelet-to-lymphocyte ratio predicts the outcomes of hepatocellular carcinoma.

BACKGROUND: There is limited information regarding NLR-PLR (the combination of the neutrophil-to-lymphocyte ratio [NLR] and platelet-to-lymphocyte ratio [PLR]) in hepatocellular carcinoma (HCC). This study aimed to assess the predictive ability of NLR-PLR in patients with resectable hepatitis B virus-related HCC within Milan criteria after hepatectomy. METHODS: Two hundred thirty-six consecutive HCC patients were included in the study. The postoperative NLR-PLR was calculated based on the data obtained on the first postoperative month after liver resection as follows: patients with both an elevated PLR and an elevated NLR, which were detected by receiver operating characteristic curve analysis, were allocated a score of 2, and patients showing one or neither of these elevations were allocated a score of 1 or 0, respectively. RESULTS: During the follow-up period, 113 patients experienced recurrence and 41 patients died. Multivariate analyses suggested that tumor-node-metastasis stage, preoperative alpha-fetal protein, and postoperative NLR-PLR were independently associated with recurrence, whereas microvascular invasion and postoperative NLR-PLR adversely impacted the overall survival. The 5-y recurrence-free and overall survival rates of the patients with a postoperative NLR-PLR of 0, 1, or 2 were 43.6%, 35.6%, or 8.3% (P < 0.001) and 82.1%, 73.0%, or 10.5% (P < 0.001), respectively. CONCLUSIONS: The postoperative NLR-PLR predicted outcomes of hepatitis B virus-related HCC patients within Milan criteria after liver resection.

Upper abdominal shape as a risk factor of extended operation time and severe postoperative complications in HCC hepatectomy through subcostal incision.

BACKGROUND: Subcostal incision is the most widely used approach in open surgery for patients with hepatocellular carcinoma (HCC). Body shape is recognised to be a factor influencing the difficulty of surgery; however, the exact impact of the increased difficulty on the patients' operation as well as the outcome has not been analysed. In this study, we retrospectively studied the possible influence of patients' body shape, tumour burden and varied surgical methods on the operation procedure and postoperative complications. METHODS: From January 2009 to December 2013, 651 patients with HCC were included in the study. We studied the patients' sex, age, body mass index, upper abdominal body shape described by the depth-to-width ratio for the trunk at the celiac axis on CT/MRI, Child-Pugh classification, tumour burden and a different liver dissection method before the surgery and used a regression model for analysis. RESULTS: Prolonged operation time is associated with advanced tumour stage, large CA ratio, previous abdominal surgery, selective hepatic vascular occlusion and dissecting with Cavitron ultrasonic surgical aspirator rather than clamp crushing. Surgical blood loss is associated with operation time, liver function and a different liver dissection method. The incidence of severe postoperative complication was 17.5% (114/651) and was associated with larger CA ratio, Child-Pugh stage B liver function and greater blood loss. CONCLUSIONS: Large upper abdominal shape is a risk factor of both prolonged operation time and severe postoperative complication. CA ratio combined with liver function and surgical blood loss has an acceptable power to predict severe postoperative complications.

Can living donor liver transplantation offer similar outcomes to deceased donor liver transplantation using expanded selection criteria for hepatocellular carcinoma?

OBJECTIVE: To compare the outcomes of living donor liver transplantation (LDLT) versus deceased donor liver transplantation (DDLT) for patients with hepatocellular carcinoma (HCC) in different selection criteria. METHODS: Data of patients with HCC who underwent liver transplantation between 2005 and 2013 at our center were reviewed. Clinical data of LDLT recipients and DDLT recipients were compared. The postoperative recurrence-free survival (RFS) rate and overall survival (OS) rate after LDLT versus DDLT were compared in the Milan recipients, the University of California, San Francisco (UCSF) recipients, the up-to-seven recipients, the Hangzhou recipients and the Chengdu recipients. RESULTS: Data of 255 patients were retrospectively reviewed in this study. Seventeen DDLT recipient and 9 LDLT recipients died during the perioperative period. Among the remaining 229 recipients (NLDLT=66, NDDLT=163), 96 patients met the Milan criteria, 123 recipients met the UCSF criteria, 135 patients met the up-to-seven criteria, 216 patients met the Hangzhou criteria, and 229 recipients met the Chengdu criteria. The overall RFS and OS rates of the Milan recipients, the UCSF recipients, the up-to-seven recipients, the Hangzhou recipients and the Chengdu recipients after LDLT and DDLT were all similar. CONCLUSION: Using well-studied selection criteria, LDLT offers similar outcomes to DDLT for patient with HCC, even using expanded selection criteria.

Neutrophil to lymphocyte ratio changes predict small hepatocellular carcinoma survival.

BACKGROUND: There is limited information available concerning the delta neutrophil to lymphocyte ratio (ΔNLR) in hepatocellular carcinoma (HCC). The present study was designed to evaluate the predictive value of dynamic change of NLR in patients who undergo curative resection for small HCC. METHODS: A retrospective cohort study was performed to analyze 189 patients with small HCC who underwent curative resection between February 2007 and March 2012. Patient data were retrieved from our prospectively maintained database. Patients were divided into two groups: group A (NLR increased, n = 80) and group B (NLR decreased, n = 109). Demographic and clinical data, overall survival (OS), and recurrence-free survival (RFS) were statistically compared and a multivariate analysis was used to identify prognostic factors. RESULTS: The 1, 3, and 5-y OS in group A was 92.7, 70.0, and 53.0%, respectively, and 96.2, 87.5, and 75.9%, respectively, for group B (P = 0.003); The corresponding 1, 3, and 5-y RFS was 58.7, 37.9, 21.8, and 81.2%, 58.5% and 53.8% for groups A and B, respectively (P <0.001). Multivariate analysis suggested that ΔNLR was an independent prognostic factor for both OS (P = 0.004, Hazard Ratio (HR) = 2.637, 95% confidence interval (CI) 1.356-5.128) and RFS (P <0.001, HR = 2.372, 95% CI 1.563-3.601). CONCLUSIONS: Increased NLR, but not high preoperative NLR or postoperative NLR, helps to predict worse OS and RFS in patients with small HCC who underwent curative resection.

Portal hemodynamics before and after liver resection and its correlation with post-hepatectomy liver failure in patients with Child-Pugh class A: analysis of 151 consecutive cases.

BACKGROUND/AIMS: Low portal velocity (PV) was found in cirrhotic patients, which was thought to be a risk factor for post-hepatectomy liver failure (PHLF). This study attempted to find out whether a correlation existed between portal hemodynamics and PHLF. METHODOLOGY: From December 2010 to December 2012, all consecutive patients with Child-Pugh class A underwent liver resection were included. PV and PF were measured by using Doppler ultrasound preoperatively and on postoperative day 3. Portal hemodynamics change was explored. Univariable and multivariable analysis were used to identify risk factors for PHLF. RESULTS: PHLF occurred in 25 of 151 patients, and persistent PHLF in 9 patients. Mean portal velocity change (PVmeanC) was significantly different between patients with PHLF and patients without PHLF, but it failed to be identified as independent predictor for PHLF in multivariate analysis, which found alanine aminotransferase (ALT) and Ishak score significantly associated with PHLF, and only ALT significantly associated with persistent PHLF. Subgroup analysis of the 73 cirrhotic patients also showed that none of the portal hemodynamic parameters were independent risk factors for PHLF or persistent PHLF. CONCLUSIONS: None of the portal hemodynamic parameters could be used to predict PHLF or persistent PHLF.
