339 Background: We explored clinical factors associated with extent of liver regeneration after hemihepatectomy to treat hepatocellular carcinoma (HCC), as well as how the extent of regeneration influences postoperative recovery of liver function. Methods: In this prospective study of 125 patients who underwent hemihepatectomy, future liver remnant volume (as a percentage of functional liver volume, %FLRV) and remnant liver volume were measured preoperatively and at 1, 5, 9 and 13 weeks postoperatively. Logistic regression was used to identify clinical factors associated with liver regeneration. Influence of liver regeneration on postoperative liver function was evaluated. Results: After hepatectomy, 1 of 125 patients (0.8%) died within 3 months, 13 (10.4%) experienced liver failure and 99 (79.2%) experienced complications. %FLRV was able to predict liver failure with an area under the receiver operating characteristic curve of 0.900, and a cut-off value of 42.7% showed sensitivity of 85.7% and specificity of 88.6%. Postoperative median growth ratio was 21.3% at 1 week, 30.9% at 5 weeks, 34.6% at 9 weeks and 37.1% at 13 weeks. Multivariate analysis identified three predictors associated with liver regeneration: FLRV < 601 cm3 (OR 0.230, 95%CI 0.074-0.717), %FLRV (OR 0.271, 95%CI 0.077-0.960) and liver cirrhosis (OR 7.740, 95%CI 2.748-21.798). At postoperative weeks 1 and 5, liver function indicators were significantly better among patients showing high extent of regeneration than among those showing low extent, but these differences disappeared by postoperative week 9. Conclusions: FLRV, %FLRV and liver cirrhosis strongly influence extent of liver regeneration after hepatectomy. %FLRV values below 42.7% are associated with greater risk of post-hepatectomy liver failure.

Multivariate analysis identified three predictors associated with liver regeneration: FLRV < 601 cm3, %FLRV, and liver cirrhosis. At postoperative weeks (POWs) 1 and 5, liver function indicators were significantly better among patients showing high extent of regeneration than among those showing low extent, but these differences disappeared by POW 9. Conclusions: FLRV, %FLRV, and liver cirrhosis strongly influence extent of liver regeneration after hepatectomy. %FLRV values below 42.7% are associated with greater risk of post-hepatectomy liver failure.

Abstract Objective A retrospective analysis of the influences of platelet (PLT) counts on liver failure and liver regeneration in patients with primary hepatocellular carcinoma (HCC) provides a treatment strategy for clinical prevention and treatment of postoperative liver failure and residual liver regeneration. Method The clinical data of 111 patients with a background of hepatitis B virus infection and who underwent (expanded) half liver resection at the First Affiliated Hospital of Guangxi Medical University from June 2012 to June 2017 were collected and statistically analyzed. Results　On the basis of the International Study Group of Liver Surgery liver failure-grading standards and Dino–Clavien postoperative complication criteria, the incidence of grade B and above liver failure was 55%, and complication II level and above was 47.5% in the PLT decline group after semihepatectomy. The incidence rates in the normal group were 26.8% and 23.9%. A statistically significant difference was determined in the two groups (P1=0.003, P2 = 0.011). The average volumes of liver hyperplasia (residual liver volume (RLV)80.4 days − RLV) in the PLT decline and normal groups were 132.09 ± 61.89 cm3 and 190.89 ± 91.98c cm3, respectively; the average rates of hyperplasia ((RLV80.4days−RLV)/RLV) were 16.59%± 7.36% and 24.78% ± 10.82%. The difference between the two groups was statistically significant (PProliferation = 0.001, PProliferation rate = 0.001). Univariable and multivariable logistic regression analyses of postoperative liver failure grade and proliferation rate in patients who underwent semihepatectomy suggested that the decrease in postoperative PLT count (PLT < 125 × 109/L) might be an independent risk factor of severe posthepatectomy liver failure (PHLF) (PHLF-B or above) and residual liver regeneration rate for patients with primary HCC after half liver resection. No death occurred. Conclusions A correlation existed between PLT count and postoperative PHLF or liver regeneration. Monitoring PLT counts after liver resection may help us predict the suffering from PHLF-B or above and severe postoperative complications.

Staged Hepatectomy

Background In patients with bilobar metastatic liver disease, surgical clearance of both liver lobes may be achieved through multiple-stage liver resections. For patients with extensive disease, a major two-staged hepatectomy consisting of resection of liver segments II and III before right-sided portal vein embolization (PVE) and resection of segments V–VIII may be performed, leaving only segments IV ± I as the liver remnant. Purpose To describe the outcome following right-sided PVE after prior complete resection of liver segments II and III. Material and Methods In this retrospective study, 15 patients (mean age = 60.4 ± 9.3 years) with liver metastases from colorectal cancer (n = 14) and uveal melanoma (n = 1) who were scheduled to undergo a major two-stage hepatectomy, were included. Total liver volume (TLV) and volume of the future liver remnant (FLR) were measured on pre- and postinterventional computed tomography (CT) scans, and standardized FLR volumes (ratio FLR/TLV) were calculated. Patient data were retrospectively analyzed regarding peri- and postinterventional complications, with special emphasis on liver function tests. Results The mean standardized post-PVE FLR volume was 26.9% ± 6.4% and no patient developed hepatic insufficiency after the PVE. Based on FLR hypertrophy and liver function tests, all but one patient were considered eligible for the subsequent right-sided hepatectomy. However, due to local tumor progression, only 9/15 patients eventually proceeded to the second stage of surgery.   Conclusion Right-sided PVE was safe and efficacious in this cohort of patients who had previously undergone a complete resection of liver segments II and III as part of a major staged hepatectomy pathway leaving only segments IV(±I) as the FLR.

Purpose: Liver failure is a major cause of early mortality followinghepatectomy. The future-remnant liver function is an important factor whenassessing the risk for postoperative liver impairment. Several techniques havebeen established for this evaluation, including the ICG test. Aim of the study isto evaluate the ICG clearance in patients scheduled for liver resectionregarding perioperative and postoperative risk factors.Methods: Thirty-one patients, scheduled for liver resection, underwent theICG test. Peri-operative and postoperative variables were recorded andanalyzed using non-parametric tests.Results: Procedures extended from wedge excisions to extendedhepatectomies. Major complications included 1 case of a non-ST elevationmyocardial infarct, 1 case of inferior vena cava thrombosis, 2 cases of liverinsufficiency and 1 case of renal failure. Two patients died due to myocardialinfarction and postoperative liver failure respectively. PDR was foundpositively correlated with total blood loss, transfusion and operation duration.Conclusions: The role of residual liver function and particularly the hepaticreserve assessment on liver surgery may be of most benefit in the routinestratification of risk, enabling surgical procedures to be performed with safety.In this study, the ICG clearance markers were found significantly correlated with perioperative risk factors in histologically „normal‟ liver parenchyma.Interpretation of ICG clearance results may appraise in these patients aninadequate hepatic reserve in the remaining parenchyma postoperatively.Thus, in addition to CT volumetry, functional assessment of the hepaticreserve with ICG may persuade the preoperative planning and preventpostoperative liver failure.

Posthepatectomy Liver Failure

Background: Posthepatectomy liver failure (PHLF) was recently defined with the corresponding recommendations as follows: grade A, no change in clinical management; grade B, clinical management with noninvasive treatment; and grade C, clinical management with invasive treatment. In this study, we identified the risk factors for grade B and C PHLF in patients with hepatocellular carcinoma (HCC). Methods: Of 339 HCC patients who underwent curative hepatic resection, 218 were included for analysis. The LHL15 index (uptake ratio of the liver to that of the liver and heart at 15 min) was measured by 99m Tc-GSA (99m technetium-labelled galactosyl human serum albumin); remnant LHL15 was calculated as LHL15 × [1 − (resected liver weight − tumor volume)/whole liver volume without tumor]. Results: A total of 163 patients were classified as having no PHLF, whereas 17, 37, and 1 patient had PHLF grade A, B, and C, respectively. There were significant differences in indocyanine green R15, serum albumin, prothrombin time, Child-Pugh classification, LHL15 and remnant LHL15 between patients with grades B/C PHLF and patients with grade A or no PHLF. Only remnant LHL15 was identified as an independent risk factor for grades B/C PHLF (p = 0.023), with a cut-off value of 0.755. Conclusions: Remnant LHL15 was an independent risk factor for grades B/C PHLF. Patients with impaired remnant LHL15 value of <0.755 should be carefully monitored for PHLF.

e16115 Background: In the past clinical practice of radiotherapy for liver cancer, liver regeneration (LR) which is beneficial to the prevention or recovery of radiation-induced liver injury, has not received enough attention. In current study, we aimed to build and validate multivariate model for liver regeneration after radiation therapy for hepatocellular carcinoma (HCC) based on data from 2 prospective studies. Methods: Thirty patients treated with preoperative downstaging radiotherapy were prospectively included in the training cohort, and 21 patients treated with postoperative adjuvant radiotherapy were included in the validation cohort. Liver regeneration was defined as an increase of more than 10% of normal liver volume in the areas of the protected hepatic segment or lobe, without Child-Pugh class decreased and tumor progression compared to pre-radiotherapy. Model and nomogram of liver regeneration after radiotherapy were developed and validated. The cut-off points of each optimal predictors were obtained using receiver-operating characteristic analysis. Risk stratification based on the cut-off point was conducted to compare the proportion of patients with liver regeneration between subgroups. Results: After radiotherapy, 12 (40%) cases in the training cohort and 13 (61.9%) cases in the validation cohort experienced liver regeneration. The model and nomogram of liver regeneration based on SVs20 (standard residual liver volume spared from at least 20 Gy) and alanine aminotransferase (ALT) showed good prediction performance (AUC = 0.759) in training cohort and performed well (AUC = 0.808) in the validation cohort. The risk stratification according to the cutoffs of SVs20 with 303.4 mL and ALT with 43 U/L demonstrated clear differentiation in risk of liver regeneration between the training(P = 0.049) and entire cohort (P = 0.032). The proportion of patients with liver regeneration decrease progressively with 88.9% in high-probability group (ALT＜43 U/L and SVs20＜303.4 mL), 60% in high-intermediate probability group (ALT ≥43 U/L and SVs20＜303.4 mL), 43.75% in low-intermediate probability group (ALT＜43 U/L and SVs20≥303.4 mL) and 33% in low- probability group (ALT≥43 U/L and SVs20≥303.4 mL). Conclusions: SVs20 and ALT are optimal predictors for liver regeneration. This simple-to-use nomogram is beneficial to the constraints of normal liver outside the radiotherapy target area and make prognosis-based decision without complex calculations.
