Background
It remains unclear whether hepatectomy for hepatocellular carcinoma should be performed as an anatomic resection (AR) or a nonanatomic resection (NAR). Because no randomized controlled trials are currently available on this topic, a meta-regression analysis was performed on available observational studies to control for confounding variables.Methods
A systematic review of studies published from 1990 to 2011 in the PubMed and Embase databases was performed. Patient and disease-free survival (DFS), postoperative mortality, and morbidity were considered as outcomes. Results are expressed as relative risk (RR) or weighted mean differences with 95?% of confidence interval.Results
Eighteen observational studies involving 9,036 patients were analyzed: 4,012 were in the AR group and 5,024 in the NAR group. Meta-analysis suggested that AR provided better 5-year patient survival (RR 1.14; P?=?0.001) and DFS than NAR (RR 1.38; P?=?0.001). However, patients in the NAR group were characterized by a higher prevalence of cirrhosis (RR 1.27; P?=?0.010), more advanced hepatic dysfunction (RR 0.90 for Child-Pugh class A; P?=?0.001) and smaller tumor size (weighted mean difference 0.36?cm; P?<?0.001) compared with patients in the AR group. Meta-regression analysis showed that the different proportion of cirrhosis in the NAR group significantly affected both 5-year patient survival (RR 1.28; P?=?0.016) and DFS (RR 1.74; P?=?0.022). Tumor size only slightly affected DFS (RR 1.72; P?=?0.076). Postoperative mortality and morbidity were unaffected (P?>?0.05 in all cases).Conclusions
Patient survival and DFS after AR seem to be superior to NAR because the worse liver function reserve in the NAR group significantly affects prognosis. 相似文献2.

Background
This study aimed to clarify the efficacy of anatomical resection (AR) for the treatment of hepatocellular carcinoma (HCC) compared with that of nonanatomical resection (NAR) based on the stratification of liver function (LF).Methods
The clinical records of 174 patients with a single HCC, 2–5 cm in diameter and without macroscopic vascular invasion, were analyzed. AR was performed in 132 patients and NAR was performed in 42 patients. The indocyanine green retention rate at 15 min (ICGR15) of the 78 patients classified as the good-LF group was 10–20 % and the ICGR15 of the 54 patients classified as the poor-LF group was 20–40 %.Results
The 5-year overall survival (OS) and disease-free survival rates of the 174 patients were 67.6 and 33.4 %, respectively. Cox proportional hazard analysis identified ICGR15 ≥20 %, liver cirrhosis, α-fetoprotein ≥100 mg/dL, and infiltrating growth as independent prognostic factors. Liver cirrhosis was significantly less frequent in patients who underwent AR than in patients who underwent NAR (52 vs. 79 %, p = 0.002). In the subgroup analysis of the good-LF group, there were no significant differences in 5-year OS after AR and NAR (73.3 vs. 65.2 %, p = 0.857). By contrast, in the subgroup analysis of the poor-LF group, the 5-year OS after AR was significantly worse than after NAR (45.3 vs. 77.4 %, p = 0.044).Conclusion
In patients with an ICGR15 ≥20 %, we recommend NAR rather than AR for the treatment of a solitary 2–5-cm-diameter HCC and without macroscopic vascular invasion. 相似文献3.

Background
Several published reports investigating the effects of interferon (IFN) therapy on survival and tumor recurrence after curative resection of hepatocellular carcinoma (HCC) have been inconclusive. The aim of this study is to investigate the efficacy of pegylated-IFN (peg-IFN) therapy after curative hepatic resection for HCC in patients infected with hepatitis C virus (HCV).Methods
Data from 175 patients who underwent curative hepatic resection for HCC associated with HCV were retrospectively collected and analyzed; 75 patients received peg-IFN therapy after surgery, whereas 100 patients did not receive IFN therapy. To overcome biases resulting from the different distribution of covariates in the two groups, a one-to-one match was created using propensity score analysis. After matching, patient outcomes were analyzed.Results
After one-to-one matching, patients (n?=?38) who received peg-IFN therapy after surgery and patients (n?=?38) who did not receive IFN therapy had the same preoperative and operative characteristics. The 3- and 5-year overall survival rates of patients who received peg-IFN therapy after hepatic resection were significantly higher than those of patients who did not receive IFN therapy (P?=?0.00135). The 3- and 5-year overall survival rates were 100 and 91.7% and 76.6 and 50.6% in the peg-IFN group and non-IFN group, respectively. There was no significant difference in disease-free survival between the two matched groups (P?=?0.886).Conclusion
Peg-IFN therapy may be effective as an adjuvant chemopreventive agent after hepatic resection in patients with HCV-related HCC. 相似文献4.

Background
Although several studies have shown that serum antithrombin III (ATIII) has anti-inflammatory effects, the prognostic value of ATIII in HCC is unknown. We investigated the influence of preoperative ATIII levels on the outcome of patients who underwent hepatectomy for hepatocellular carcinoma (HCC).Methods
Data from 440 patients (314 patients with ATIII ??70?% and 126 patients with ATIII <70?%) who underwent curative hepatectomy for HCC were retrospectively collected and analyzed. To overcome bias due to the different distribution of covariates for the 2 groups, propensity score matching was performed on the patients, and outcomes were compared.Results
The propensity score analysis revealed that 65 patients with ATIII of ??70?% (group 1) and 65 patients with ATIII of <70?% (group 2) had the same preoperative and operative characteristics (excluding the ATIII level). The overall survival rate and the disease-free survival rate was significantly higher in group 1 than in group 2 (P?=?0.005 and 0.011, respectively). Multivariate analysis showed that ATIII was a significant favorable factor for overall survival and disease-free survival of patients with HCC after curative hepatectomy.Conclusions
The prognosis of patients with HCC was found to be associated with preoperative antithrombin III levels. ATIII may be useful for predicting outcomes of patients with HCC after curative hepatectomy. 相似文献5.

Background
Solitary hepatocellular carcinoma (HCC) is a good candidate for surgical resection. However, the significance of the size of the tumor in solitary HCC remains unclear.Objective
The aim of this study was to evaluate the impact of tumor size on overall and recurrence-free survival of patients with solitary HCC.Materials
We retrospectively reviewed 616 patients with histologically confirmed solitary HCC who underwent curative surgical resection between 1994 and 2010. The characteristics and prognosis of patients with HCC were analyzed stratified by tumor size.Results
A total of 403 patients (65 %) had tumors <5 cm, 172 (28 %) had tumors between 5 and 10 cm, and 41 (7 %) had tumors >10 cm. The incidence of microvascular invasion, satellite nodules, and advanced tumor grade significantly increased with tumor size. The 5-year overall and recurrence-free survival rates of HCC <5 cm were 69.6 % and 32 %, respectively, which were significantly better than those of HCC between 5 and 10 cm (58 % and 26 %, respectively) and HCC >10 cm (53 % and 24 %, respectively). On multivariate analysis, cirrhosis (p = 0.0307), Child–Pugh B (p = 0.0159), indocyanine green retention rate at 15 min >10 % (p = 0.0071), microvascular invasion (p < 0.0001), and satellite nodules (p = 0.0009) were independent predictors of poor survival, whereas tumor size >5 cm was not.Conclusion
Although recurrence rates are high, surgical resection for solitary HCC offers good overall survival. Tumor size was not a prognostic factor. Solitary large HCC >10 cm would be a good candidate for hepatectomy as well as solitary HCC between 5 and 10 cm. 相似文献6.

Objective
This study aims to analyze the outcomes of patients with Child-Pugh A class cirrhosis and a single hepatocellular carcinoma (HCC) up to 5 cm in diameter who underwent liver transplantation vs. resection.Methods
During 2007 to 2012, 282 Child-Pugh A cirrhotic patients with a single HCC up to 5 cm in diameter either underwent liver resection (N?=?243) or received liver transplantation (N?=?39) at our center. Patient and tumor characteristics and outcomes were analyzed.Results
Patients who underwent liver transplantation had a better recurrence-free survival (RFS) vs. those who underwent liver resection. However, the 5-year survival rates after these two treatments were comparable. Similar results were observed when we analyzed patients with a HCC less than 3 cm, and for patients with portal hypertension. In the multivariate analysis, tumor differentiation, difference of primary treatment, and presence of microvascular invasion were associated with postoperative recurrence. However, only differentiation negatively impacted overall survival after operation.Conclusion
Although more recurrences were observed in Child A cirrhotic patients with a single HCC up to 5 cm after liver resection, liver resection offers a similar 5-year survival to liver transplantation, even for patients with portal hypertension. 相似文献7.

Background
Performance status (PS) is closely linked with survival in patients with hepatocellular carcinoma (HCC). We investigated its impact on treatment strategy for small HCC(s).Methods
A total of 360 and 362 HCC patients within the Milan criteria undergoing surgical resection (SR) and radiofrequency ablation (RFA), respectively, were prospectively enrolled. Patients were classified into PS 0 (n = 558) and PS ≥1 (n = 164) groups. Propensity score analysis was performed, and 168 and 35 matched pairs were selected from patients with PS 0 and ≥1, respectively.Results
The SR group was younger and had a higher male-to-female ratio, higher prevalence of hepatitis B, lower prevalence of hepatitis C, better PS, better liver functional reserve, and larger tumor burden than the RFA group (all p < 0.05). Among patients with PS 0, the SR group was consistently younger, less cirrhotic, and had larger tumor burden (all p < 0.05). The long-term survival was comparable between SR and RFA group in patients with PS 0. After propensity score matching, SR provided significantly better long-term survival than RFA for patients within the Milan criteria classified as PS 0 (p = 0.016); the Cox proportional hazards model showed consistent results. There was no significant difference of overall survival between the SR and RFA group in patients with PS ≥1 before or after propensity score matching (both p > 0.05).Conclusions
For HCC patients within the Milan criteria and classified as PS 0, SR provides a better long-term survival compared with RFA. Performance status may enhance treatment selection and stratify the risk of survival in these patients. 相似文献8.

Background
Treatment for patients with intermediate-stage hepatocellular carcinoma (HCC) is controversial. This study compared the long-term survival of patients beyond the Milan criteria who received surgical resection (SR) or transarterial chemoembolization (TACE).Methods
A total of 268 and 455 HCC patients beyond the Milan criteria undergoing SR and TACE, respectively, were retrospectively evaluated. After propensity score analysis to adjust for baseline differences, 146 pairs of matched patients were selected from each treatment arm. Long-term survival was compared by the Kaplan?CMeier method. Independent prognostic predictors were determined by the Cox proportional hazards model.Results
Long-term survival was significantly better for the SR group by univariate survival analysis (P?.001). In the Cox model, SR was identified as an independent predictor of better prognosis (hazard ratio?=?0.3, 95% confidence interval [95% CI]: 0.23?C0.4; P?.001). Despite similar baseline characteristics in the propensity score model, patients who underwent SR had significantly better survival than patients who underwent TACE (P?.001). Patients receiving TACE had 2.56-fold increased risk of long-term mortality in the propensity model (95% CI: 1.73?C3.78). The SR and TACE groups had comparable 30- and 90-day posttreatment mortality. The Cox model consistently disclosed the significant superiority of SR in terms of long-term survival in the propensity score model (P?.001).Conclusions
For HCC patients beyond the Milan criteria, SR is considered equally safe as TACE and provides better long-term survival. SR may be regarded as the priority treatment for these patients. 相似文献9.

Background
The present study aimed to clarify the clinicopathologic features of long-term disease-fee survival after resection of hepatocellular carcinoma (HCC).Methods
This retrospective study identified 940 patients who underwent curative resection of HCC between 1991 and 2000 at five university hospitals. Seventy-four patients with 10 years of recurrence-free survival were identified and followed up. They were divided into two groups, 60 recurrence-free and 14 with recurrence after a 10-year recurrence-free period.Results
Overall survival rates of recurrence and non-recurrence groups were 68 and 91 % at 16 years, and 34 and 91 % at 20 years (p = 0.02), respectively. There were five (36 %), and two deaths (3 %), respectively, after 10 recurrence-free years. A second resection for recurrence was performed in four patients (29 %), and mean survival was 15.3 years after the first hepatectomy. Although three patients in the non-recurrence group (5 %) developed esophageal and/or gastric varices, seven patients in the recurrence group (50 %) developed varices during 10 years (p < 0.0001). In multivariate analysis, preoperative and 10-year platelet count was identified as a favorable independent factor for maintained recurrence-free survival after a 10-year recurrence-free period following curative hepatic resection of HCC.Conclusions
Recurrence of HCC may occur even after a 10-year recurrence-free period. Long-term follow-up after resection of HCC is important, and should be life-long. Patients with higher preoperative and 10-year platelet counts are more likely to have long-term survival after resection. A low platelet count, related to the degree of liver fibrosis, is a risk factor for recurrence and survival of HCC after curative resection. 相似文献11.

Background
The long-term survival in hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT) who received surgical resection (SR) or transarterial chemoembolization (TACE) remains unclear. We compared the efficacy of SR and TACE by using a propensity score analysis.Methods
A total of 247 and 181 HCC patients with PVTT undergoing SR and TACE, respectively, were evaluated. One hundred eight pairs of matched patients were selected from each treatment arm by using a propensity score analysis.Results
Of all patients, the estimated 1-, 3-, and 5-year survival rates of patients receiving SR and TACE were 85 versus 60 %, 68 versus 42 %, and 61 versus 33 %, respectively (p < 0.001). Patients selected for SR were significantly younger and had better liver functional reserve, performance status, and smaller tumor burden. In the propensity model, the survival benefit of SR remained significant. The estimated 1-, 3-, and 5-year survival rates of patients receiving SR and TACE were 84 versus 71 %, 69 versus 50 %, and 59 versus 35 %, respectively (p = 0.004). The two groups of patients in the propensity score analysis were similar in baseline characteristics. In the Cox proportional hazards model, patients receiving TACE had a 2.044-fold increased risk of mortality compared with patients receiving SR (95 % confidence interval: 1.284–3.252, p = 0.003).Conclusions
For either unselected patients or patients in the propensity model, SR provides significantly better long-term survival than TACE. SR should be considered as a priority treatment in this subgroup of HCC patients. 相似文献12.

Background
While spontaneously ruptured hepatocellular carcinoma (HCC) has a poor prognosis, the true impact of a rupture on survival after hepatic resection is unclear.Methods
Fifty-eight patients with ruptured HCC and 1922 with non-ruptured HCC underwent hepatic resection between 2000 and 2013. To correct the difference in the clinicopathological factors between the two groups, propensity score matching (PSM) was used at a 1:1 ratio, resulting in a comparison of 42 patients/group. We investigated outcomes in all patients with ruptured HCC and compared outcomes between the two matched groups.Results
Of the 58 patients with ruptured HCC, 7 patients (13 %) died postoperatively. Overall survival (OS) rate at 5 years after hepatic resection was 37 %. Emergency hepatic resection was an independent risk factor for in-hospital death and Child-Pugh class B for unfavorable OS in multivariate analysis. Clinicopathological variables were well-balanced between the two groups after PSM. No significant differences were noted in incidence of in-hospital death (ruptured HCC 12 % vs non-ruptured HCC 2 %, p?=?0.202) or OS rate (5/10-year; 42 %/38 % vs 67 %/30 %, p?=?0.115).Conclusion
Emergency hepatic resection should be avoided for ruptured HCC in Child-Pugh class B patients. Rupture itself was not a risk for unfavorable surgical outcomes.13.
Aims
The aim of this study was to compare the effectiveness and safety of hepatic resection versus open-approach RFA (ORFA) for small hepatocellular carcinomas (HCC) within Milan criteria after successful downstaging therapy by transcatheter arterial chemoembolization.Material and Methods
Between February 2005 and February 2008, a total of 110 patients with advanced HCC met the Milan criteria after successful downstaging therapy; 58 patients then underwent hepatic resection and 52 received ORFA. Outcomes, including short- and long-term morbidity, 1-, 3-, and 5-year mortality and HCC-free survival, were analyzed and compared between the two groups.Results
Patients in the hepatic resection and ORFA groups showed similar baseline characteristics and downstaging protocols. The ORFA group showed less blood loss, lower hospital costs, shorter surgical time, and fewer hospital stay days (P?<?0.05). The 1-, 3-, and 5-year overall survival rates were 94.8, 86.2, and 79.3 %, respectively, with liver resection and 96.2, 82.7, and 76.9 % with ORFA (P?=?0.772). The 1-, 3-, and 5-year recurrence-free survival rates were 93.1, 81.0, and 77.6 % with resection and 94.2, 76.9, and 73.1 % with ORFA (P?=?0.705). The ORFA patients suffered fewer postoperative complications (P?=?0.09), particularly among the cases of central HCC (P?=?0.015).Conclusion
Resection and ORFA achieved similar survival benefits in the management of HCC within Milan criteria after successful downstaging. The decreased blood loss, hospital costs, surgical time, and hospital stay days, and lower complication rates in central cases render ORFA a preferred treatment option. 相似文献14.

Objective
Postoperative complications strongly impact the postoperative course and long-term outcome of patients who underwent liver resection for colorectal liver metastases (CRLM). Among them, infectious complications play a relevant role. The aim of this study was to evaluate if infectious complications still impact overall and disease-free survival after liver resection for CRLM once patients were matched with a propensity score matching analysis based on Fong’s criteria.Methods
A total of 2281 hepatectomies were analyzed from a multicentric retrospective cohort of hepatectomies. Patients were matched with a 1:3 propensity score analysis in order to compare patients with (INF+) and without (INF?) postoperative infectious complications.Results
Major resection (OR?=?1.69 (1.01–2.89), p?=?0.05) and operative time (OR?=?1.1 (1.1–1.3), p?=?0.05) were identified as risk factors of infectious complications. After propensity score matching, infectious complications are associated with overall survival (OS), with 1-, 3-, 5-year OS at 94, 81, and 66% in INF? and 92, 66, and 57% in INF+ respectively (p?=?0.01). Disease-free survival (DFS) was also different with regard to 1-, 3-, 5-year survival at 65, 41, and 22% in R0 vs. 50, 28, and 17% in INF+ (p?=?0.007).Conclusion
Infectious complications are associated with decreased overall and disease-free survival rates.15.

Background and Aims
Performance status is tightly linked with survival in patients with hepatocellular carcinoma (HCC). We investigated the impact of performance status on HCC patients beyond the Milan criteria receiving surgical resection (SR) or transarterial chemoembolization (TACE).Methods
A total of 909 patients with HCC beyond the Milan criteria were retrospectively analyzed by using propensity score analysis.Results
The baseline characteristics were similar between the SR and TACE group for patients with performance status 0 in the propensity model. More patients in the TACE group with performance status ≥1 had Child-Turcotte-Pugh class A compared to the SR group (p?=?0.044) in the propensity model. SR provided significantly better long-term overall survival than TACE in patients selected in the propensity model regardless of performance status (both p?0.05). In the Cox proportional hazards model, TACE was associated with 2.279-fold and 3.066-fold increased risk of mortality in performance status 0 and performance status ≥1 in the propensity model (95 % confidence interval, 1.476–3.591 and 1.570–5.989), respectively.Conclusions
For either performance status 0 or ≥1 HCC patients beyond the Milan criteria, SR provides significantly better long-term survival than TACE. SR should be considered a priority treatment in these patients independent of performance status. 相似文献16.

Background
Serum alpha-fetoprotein (AFP) is frequently used to predict posthepatectomy outcomes in patients with hepatocellular carcinoma (HCC), but its predictive value is still not established. Therefore, we assessed the prognostic significance of AFP status.Methods
Of 525 patients undergoing curative hepatectomy for HCC, 290 had preoperative AFP levels of ??20?ng/mL (AFP-positive group) and 235 had AFP levels of <20?ng/mL (AFP-negative group). We compared the 2 groups with respect to time-to-recurrence, using the inverse probability of treatment weighted (IPTW) for the entire cohort and propensity score matching, and the cumulative incidence of HCC-specific mortality using competing risks regression.Results
During follow-up (median duration 64?months, range 2?C137?months), HCC recurred in 54.9?% of the AFP-negative group and 52.4?% of the AFP-positive group; there was no death without recurrence. After IPTW adjustment, time-to-recurrence did not differ in the 2 groups (hazard ratio [HR] 0.86, 95?% confidence interval [95?% CI] 0.66?C1.12; P?=?0.28). In a propensity-score matched cohort (152 pairs), time-to-recurrence data were similar to those obtained by IPTW adjustment (HR 0.91, 95?% CI 0.65?C1.25; P?=?0.55). There was no difference in recurrence pattern (site and stage) or treatment between the 2 groups even after propensity-score matching. The adjusted HR evaluating the impact of AFP positivity on the risk of HCC-specific mortality was 0.77 (95?% CI 0.54?C1.08; P?=?0.13) A multivariable competing risks analysis also failed to reveal a significant correlation between baseline AFP level and HCC-specific mortality in the AFP-positive group.Conclusions
Preoperative AFP levels are not useful for predicting recurrence or survival endpoints following curative hepatectomy for HCC. 相似文献17.

Background
The aim of this study was to investigate the clinical characteristics and outcomes of elderly patients (≥70 years old) undergoing curative hepatectomy for hepatocellular carcinoma (HCC).Methods
Clinicopathological data and treatment outcomes in 100 elderly patients (≥70 years old) and 120 control patients (≤70 years old) with HCC who underwent curative hepatectomy between 2000 and 2011 were retrospectively collected and compared.Results
The overall survival rate was similar between the two groups, but the disease-free survival rate was worse in the elderly group when compared with the control group. Prognostic factors for overall and disease-free survival were the same when comparing the two groups. The elderly group had higher rate of females (p?=?0.0230), higher hepatitis C virus infection rate (p?=?0.0090), higher postoperative pulmonary complication rate (p?=?0.0484), lower rate of response to interferon (IFN) therapy (p?=?0.0203) and shorter surgical time (p?=?0.0337) when compared with the control group. The overall recurrence rate was higher in the elderly group than in the control group (p?=?0.0346), but the rate of recurrence within 2 years after the operation was similar when comparing the two groups.Conclusion
The survival of elderly patients with HCC was similar to that of younger patients. However, the disease-free survival was worse in elderly patients than in younger patients. Aggressive antiviral therapy (e.g. IFN therapy) may be necessary to improve the disease-free survival, even in elderly patients. Additionally, clinicians should be aware of the risk of pulmonary complications in elderly patients after hepatectomy. 相似文献18.

Background
We hypothesized that microvascular invasion (MVI) and post-resection prognosis in patients with solitary hepatocellular carcinoma (HCC) could be predicted using blood tumor markers and tumor volume (TV). We intended to identify a simple surrogate marker of HCC via a combination of clinical variables.Methods
This retrospective study used the strictly selected development cohort (n?=?1176) and validation cohort (n?=?551) containing patients who underwent curative resection of solitary HCC.Results
In the development cohort study, the median values were 13.7 mL for TV, 24.2 ng/mL for α-fetoprotein (AFP), and 75 mAU/mL for des-γ-carboxy prothrombin (DCP); there was no correlation among these three factors (r 2?≤?0.237, p?<?0.001). The 1-, 3-, and 5-year rates were 22.4, 41.7, and 46.8 % for tumor recurrence and 93.6, 84.0, and 78.2 % for patient survival, respectively. Independent risk factors for both tumor recurrence and patient survival were tumor diameter >5 cm or TV >50 mL, MVI, satellite nodules, and high DCP. Multiplication of AFP, DCP, and TV (ADV score) resulted in prediction of MVI at a cutoff of 5log with sensitivity of 73.9 % and specificity of 66.7 %. Patient stratifications according to ADV score with cutoffs of 5log alone, 6log and 9log, and its combination with MVI showed significant prognostic differences (all p?<?0.001). These prognostic significances were reliably reproduced in the validation cohort study (all p?<?0.001).Conclusions
We suggest that ADV score is an integrated surrogate marker of HCC prognosis. We believe that it can be used to predict MVI and post-resection prognosis for solitary HCC.19.

Background
Posthepatectomy liver failure (PHLF) is a major complication after hepatectomy. As there was no standardized definition, the International Study Group of Liver Surgery (ISGLS) defined PHLF as increased international normalized ratio and hyperbilirubinemia on or after postoperative day 5 in 2010. We evaluated the impact of the ISGLS definition of PHLF on hepatocellular carcinoma (HCC) patients.Methods
We retrospectively analyzed 210 consecutive HCC patients who underwent curative hepatectomy at our facility from 2005 to 2010. The median follow-up period after hepatectomy was 35.2 months.Results
Thirty-nine (18.6 %) patients fulfilled the ISGLS definition of PHLF. Overall survival (OS) rates at 1, 3, and 5 years in patients with/without PHLF were 69.1/93.5, 45.1/72.5, and 45.1/57.8 %, respectively (P?=?0.002). Recurrence-free survival (RFS) rates at 1, 3, and 5 years in patients with/without PHLF were 40.9/65.9, 15.7/38.3, and 15.7/20.3 %, respectively (P?=?0.003). Multivariate analysis revealed that PHLF was significantly associated with both OS (P?=?0.047) and RFS (P?=?0.019). Extent of resection (P?<?0.001), intraoperative blood loss (P?=?0.002), and fibrosis stage (P?=?0.040) were identified as independent risk factors for developing PHLF.Conclusion
The ISGLS definition of PHLF was associated with OS and RFS in HCC patients, and long-term survival will be improved by reducing the incidence of PHLF. 相似文献20.
