RESUMO
BACKGROUND: This study aimed to examine whether the coefficient of variation (CV) in the hepatobiliary-phase (HBP) of Gd-EOB-DTPA-MRI could be an independent predictive factor for tumor progression. METHODS: Patients who underwent Gd-EOB-DTPA-MRI before Atezolizumab/bevacizumab therapy at six affiliated institutions between 2018 and 2022 were included. CV for each patient was calculated as the mean value for up to five tumors larger than 10 mm, and CV of the whole tumor was calculated using LIFEx software. The tumor response was evaluated within 6-10 weeks. The primary endpoint was to investigate the predictive factors, including CV, related to tumor progression using logistic regression analysis. The secondary endpoints were tumor response rate and progression-free survival (PFS) based on CV. RESULTS: Of the 46 enrolled patients, 13 (28.3%) underwent early progressive disease. Multivariate analysis revealed that a high CV (≥0.22) was an independent predictive factor for tumor progression (p = 0.043). Patients with a high CV had significantly frequent PD than those with a low CV (43.5 vs. 13.0%, p = 0.047). Patients with a high CV tended to have shorter PFS than those with a low CV (3.5 vs. 6.7 months, p = 0.071). CONCLUSION: Quantitative analysis using CV in the HBP of Gd-EOB-DTPA-MRI may be useful for predicting tumor progression for atezolizumab/bevacizumab therapy.
RESUMO
Introduction Abdominal angiography procedures such as transarterial chemoembolization (TACE) are essential for hepatocellular carcinoma treatment. One method commonly used is transfemoral access (TFA). However, issues associated with this method, which include postoperative compression of the puncture site and long periods of bed rest, can affect patient satisfaction. Thus, transradial access (TRA), a minimally invasive treatment method that improves treatment quality, was developed for TACE. This retrospective, multicenter study aimed to investigate the efficacy and safety of abdominal angiography using the radial artery approach. Methods In total, 1,601 patients underwent abdominal angiography using TRA and received treatment (radial access for visceral intervention (RAVI)) at 14 institutions in Japan. The treatment time, procedure completion rate, patient satisfaction, and complications were investigated. Results The success rate of RAVI was 99.4%, and the complication rate was 1.2%. Approximately 98.2% of the patients requested the radial artery approach again. There were no significant differences in the success rate of RAVI and the incidence of complications based on the operator's years of experience or the patient's age. Some patients developed minor complications such as puncture site bleeding, hematoma, vascular pain, and vasospasm. Further, serious complications (cerebral infarction (n = 1), cerebellar infarction (n = 1), and aortic dissection (n = 1)) were observed. Conclusion Similar to the conventional TFA, RAVI helped in facilitating peritoneal angiography safely. In abdominal angiography, this method can reduce patient burden and can be widely used in the future from the perspective of clinical benefit.
RESUMO
Left-sided portal hypertension (LSPH) causes varices and splenomegaly due to splenic vein issues. Colonic varices are rare and lack standardized treatment. We report the successful treatment of colonic varices caused by LSPH, by addressing both the afferent and efferent veins. A 70-year-old man with distal cholangiocarcinoma had surgery without splenic vein resection, leading to proximal splenic vein stenosis and varices at multiple locations. Percutaneous transhepatic splenic venography revealed that collateral veins flowed into the ascending colonic varices and returned to the portal vein. Complete thrombosis of the varices was achieved by injecting sclerosants and placing coils in both the afferent and efferent veins. The procedure was safe and effective, with no variceal recurrence. This approach provides a minimally invasive option for treating colonic varices associated with LSPH.
RESUMO
A 55-year-old patient was admitted for variceal treatment, a complication of chronic portal hypertension and liver cirrhosis. Imaging studies revealed prominent duodenal varices, the pancreaticoduodenal vein as its afferent pathway, a drainer vessel into the inferior vena cava, and a paraumbilical vein. We successfully performed complete obliteration of the varix, including its afferent and efferent vessels, via the paraumbilical vein approach.

The standard treatment for ruptured duodenal varices remains to be established. Emergency balloon-occluded retrograde transvenous obliteration is challenging in patients with bleeding because re-rupture of varices can occur due to increased pressure when using the retrograde approach. Herein, we describe a case in which a catheter was retrogradely advanced to the afferent vein beyond bleeding duodenal varices; however, the varices re-ruptured during coil embolization, and a part of the catheter was deviated into the intestinal tract. The rupture site was embolized by liquid embolic materials from the microcatheter. Embolization via retrograde approach needs to be carefully performed.
RESUMO
AIM: Patients with liver cirrhosis and portosystemic shunt occasionally develop reversed portal flow in the portal venous system. The factors contributing to reversed portal flow in these patients remain unclear. The aim of this study was to identify factors contributing to reversed portal flow in patients with portosystemic shunts based on four-dimensional computed tomography (4DCT), which visualized flow dynamics in the portal venous system. METHODS: Data from 34 consecutive patients with portosystemic shunts who had undergone 4DCT before interventional radiology procedures were retrospectively investigated in this study. Uni- and multivariate analyses were performed to identify factors contributing to reversed portal flow. RESULTS: Flow dynamics could be visualized on 4DCT in 32 of the 34 patients. Fifteen patients had forward portal flow; 17 had reversed portal flow. The main portal, splenic, and superior mesenteric veins displayed reversed portal flow in five, 12, and five vessels, respectively. Portosystemic shunt originating from splenic and superior mesenteric veins, worse albumin-bilirubin score, and small main portal vein diameter were significant factors contributing to reversed portal flow in both univariate (p = 0.049, p = 0.027, and p = 0.002) and multivariate (odds ratio [OR] 6.345, p = 0.012; OR 4.279, p = 0.039; and OR 5.516, p = 0.019) analyses. CONCLUSIONS: The reversed portal flow was visualized on 4DCT. Portosystemic shunt originating distant to the liver, worse albumin-bilirubin score, and small diameter of the main portal vein were factors contributing to reversed flow in the portal venous system.
RESUMO
Recent genetic analyses revealed genetic heterogeneity in hepatocellular carcinoma (HCC), although it remains unclear how genetic alterations contribute to the multistage progression of HCC, especially the early step from hypovascular liver nodules to hypervascular HCC. We conducted multiregional whole-genome sequencing on HCCs with a nodule-in-nodule appearance, consisting of inner hypervascular HCC surrounded by hypovascular HCC arising from a common origin, and identified point mutations, structural variations, and copy-number variations in each specimen. According to the genetic landscape of the inner and outer regions, together with the pathological and radiological findings, we examined the stepwise evolution of cancer cells from slow-growing HCC to rapid-growing HCC. We first demonstrated that most tumor cells consisting of hypovascular well-differentiated HCCs already harbored thousands of point mutations and even several structural variations, including chromosomal translocations and chromothripsis, as the trunk events. Telomerase reverse transcriptase (TERT)-associated aberrations, including promoter mutations, chromosomal translocation, and hepatitis B virus DNA integration, as well as abnormal methylation status, were commonly detected as the trunk aberrations, while various liver cancer-related genes, which differed in each case, had additionally accumulated in the inner dedifferentiated nodules. Further, differences in the trunk and branch mutational signatures suggested a multistep contribution to the mutagenesis in each case. In conclusion, genomic alterations associated with the TERT gene could be the key driver events to form the hypovascular HCC, and additional case-specific driver mutations accumulate during the progression phase, forming intra- and inter-tumoral heterogeneity, confirming the importance of genetic testing before targeting therapy. These data shed light on the process of multistep hepatocarcinogenesis and will be helpful toward investigating new therapeutic strategies for HCC. © 2020 The Pathological Society of Great Britain and Ireland.

Lenvatinib is a novel multikinase inhibitor that has recently shown antitumor activity against hepatocellular carcinoma (HCC) in a phase III trial. We report the case of a woman in whom lenvatinib showed long-term antitumor activity, and in whom computed tomography (CT) scans revealed a series of suggestive radiological changes on the intratumor vascularity. A 68-year-old woman with hepatitis C virus-related liver disease presented with multiple HCCs. Following previous therapy, including six sessions of transcatheter arterial chemoembolization, we introduced lenvatinib monotherapy. Lenvatinib could rapidly cause hypovascularity in the main hypervascular target lesion, and portal vein tumor thrombosis also became undetectable 11 months after the initiation of lenvatinib. These radiological changes suggested that lenvatinib could exert not only anti-angiogenic activity but also direct antitumoral effect. Of note, CT scans during lenvatinib treatment revealed the target lesion as a low-density area in the early arterial phase, whereas scans during drug interruption due to proteinuria showed that the lesion was enhanced in the arterial phase. Finally, near-complete response could be achieved as the best response. We successfully managed various adverse events including proteinuria and hypertension, and the patient was able to continue this lenvatinib therapy for more than 4 years with well-controlled general condition. We report the first case of a patient with HCC in whom lenvatinib monotherapy demonstrated long-term antitumor activity. Suggestive radiological changes reflecting intratumor vascularity as presented here should be considered in patients receiving lenvatinib for HCC.
RESUMO
OBJECTIVE: The purpose of this study is to identify points useful in the imaging differentiation of hepatocellular carcinoma (HCC) showing hyperintensity on the hepatobiliary phase of gadoxetic acid-enhanced MRI and focal nodular hyperplasia (FNH) and FNH-like nodules. MATERIALS AND METHODS: We enrolled consecutive 51 pathologically diagnosed HCCs that were hyperintense on hepatobiliary phase imaging (47 patients, including 44 with cirrhosis) and 10 FNHs and eight FNH-like nodules (16 patients, including five with cirrhosis). Imaging findings of dynamic CT and gadoxetic acid-enhanced MRI were assessed by two radiologists and compared between HCC and FNH. RESULTS: The apparent diffusion coefficient (ADC) was lower in hyperintense HCC than in FNH (p = 0.004). The enhancement patterns of hyperintense HCC and FNH at dynamic CT were significantly different (p < 0.0001), with 95.9% of HCCs and 22.2% of FNHs showing arterial phase enhancement with a washout pattern, and 4.1% of HCCs and 77.8% of FNHs showing arterial phase enhancement without a washout pattern. The frequency of coronalike enhancement was 84.3% in hyperintense HCCs versus 11.1% in FNHs (p < 0.0001). The signal distribution on the hepatobiliary phase was significantly different between hyperintense HCCs and FNHs (p = 0.0002). The frequency of a capsulelike rim was 88.2% versus 22.2%, that of a mosaic appearance was 72.5% versus 11.1%, and that of a central scar was 0% versus 55.6% in hyperintense HCCs versus FNHs (all p < 0.0001). Multivariate logistic regression analysis showed that ADC ratio (p = 0.03; odds ratio, 0.12) and enhancement pattern at dynamic CT (p = 0.04; odds ratio, 16.21) were the independent factors for differentiation between hyperintense HCC and FNH. CONCLUSION: For the diagnosis of hyperintense HCC differentiated from FNH and FNH-like nodule, arterial phase enhancement and washout pattern at dynamic CT and decrease of ADC ratio would be important findings.

Background and study aims Rectal neuroendocrine tumors grade 1 (NET G1; carcinoid)â≤â10âmm in diameter often extend into the submucosa, making their complete histological resection difficult using endoscopic techniques. Endoscopic submucosal resection with a ligation device (ESMR-L) and endoscopic submucosal dissection (ESD) are commonly used to overcome these difficulties. We also previously reported that underwater endoscopic mucosal resection (UEMR) could facilitate resection of rectal NET G1.âThis study aimed to evaluate the safety and efficacy of UEMR for removing rectal NET G1â≤â10âmm in diameter. 6 consecutive patients with rectal NET G1â≤â10âmm in diameter underwent UEMR at our hospital. The rate of en bloc resection was 100â%, and the rate of R0 resection was 83â%. The median procedure time was 8âmin (range 5â-â12âmin). No perforations or delayed bleeding occurred in this study. In conclusion, UEMR allows the safe and reliable resection of rectal NET G1â≤â10âmm in diameter with comparable results to ESMR-L or ESD, including high en bloc and R0 resection rates with no increase in significant adverse events. A multicenter trial is required to confirm the validity of the present results.
RESUMO
AIM: The aim of this study is to clarify the correlation of the co-activation of ß-catenin and hepatocyte nuclear factor (HNF)4α with the findings of gadoxetic acid-enhanced magnetic resonance imaging (MRI), organic anion transporting polypeptide (OATP)1B3 expression, and histological findings in hepatocellular carcinoma (HCC). METHODS: One hundred and ninety-six HCCs surgically resected from 174 patients were enrolled in this study. The HCCs were classified into four groups by immunohistochemical expression of ß-catenin, glutamine synthetase (GS), and HNF4α: (i) ß-catenin/GS (positive [+]) HNF4α (+); (ii) ß-catenin/GS (+) HNF4α (negative [-]); (iii) ß-catenin/GS (-) HNF4α (+); and (iv) ß-catenin/GS (-) HNF4α (-). We compared the four groups in terms of the enhancement ratio on the hepatobiliary phase of gadoxetic acid-enhanced MRI, immunohistochemical organic anion transporter polypeptide (OATP)1B3 (a main uptake transporter of gadoxetic acid) expression and histological features, overall survival, and no recurrence survival. The Kruskal-Wallis test, Steel-Dwass multiple comparisons test, Fisher's exact test, and log-rank (Mantel-Cox) test were used for statistical analyses. RESULTS: Enhancement ratio on gadoxetic acid-enhanced MRI in HCC with ß-catenin/GS (+) HNF4α (+) was significantly higher than those of the other three groups (P < 0.001). The OATP1B3 grade was also significantly higher in HCC with ß-catenin/GS (+) HNF4α (+) (P < 0.001). Hepatocellular carcinoma with ß-catenin/GS (+) HNF4α (+) showed the highest differentiation grade as compared to the other groups (P < 0.004). There were no significant differences in portal vein invasion, macroscopic growth pattern, or prognosis analyses between the four groups. CONCLUSION: Co-activation of ß-catenin and HNF4α would promote OATP1B3 expression, and consequently higher enhancement ratio on gadoxetic acid-enhanced MRI and higher differentiation grade in HCC.
RESUMO
The present study aimed to examine the impact of sarcopenia, defined as low muscle mass on computed tomography (CT), prior to sorafenib therapy on the clinical outcomes of patients with hepatocellular carcinoma (HCC) receiving sorafenib therapy. In total, 232 patients with unresectable HCC (median age, 72 years) were analyzed, and the extent of sarcopenia was assessed using CT. Cross-sectional areas (cm2) of the skeletal muscles at the third lumbar vertebra level were determined by manual outlining on the CT images. The cross-sectional areas were normalized for height [skeletal muscle index (SMI), cm2/m2]. Based on the findings of previous studies, male patients with SMI ≤36.2 cm2/m2 and female patients with SMI ≤29.6 cm2/m2 were defined as having sarcopenia. The baseline characteristics, overall survival (OS) rates, progression-free survival (PFS) rates and best treatment response of the sarcopenia group were retrospectively compared with those of the non-sarcopenia group, and the factors associated with OS and PFS were examined. Sarcopenia was observed in 151 patients (65.1%). There were 165 patients with Child-Pugh A and 67 with Child-Pugh B cirrhosis. In the sarcopenia group, the median treatment duration was 66 days, whereas in the non-sarcopenia group it was 103 days (P=0.001). The median OS time was 174 days in the sarcopenia group and 454 days in the non-sarcopenia group (P<0.0001). The median PFS was 77 days in the sarcopenia group and 106 days in the non-sarcopenia group (P=0.0131). Multivariate analysis identified sarcopenia to be an independent predictor of OS (hazard ratio, 0.365; P<0.0001). The objective response rate and disease control rate in the sarcopenia group were significantly lower, compared with those in the non-sarcopenia group (P=0.0146 and P=0.0151, respectively). In conclusion, sarcopenia may be an indicator of poor clinical course in patients with HCC receiving sorafenib.
RESUMO
BACKGROUND AND STUDY AIMS: Cold snare polypectomy (CSP) for small colorectal polyps has lower incidence of adverse events, especially delayed postpolypectomy bleeding (DPPB). However, few data are available on comparisons of the incidence of DPPB of CSP and hot polypectomy (HP). The aim of this study was to evaluate the incidence of DPPB after CSP and compare it with that of HP. A propensity score model was used as a secondary analysis. PATIENTS AND METHODS: This was a retrospective cohort study conducted in a single municipal hospital. We identified 539 patients with colorectal polyps from 2âmm to 11âmm in size who underwent CSP (804 polyps in 330 patients) or HP (530 polyps in 209 patients) between July 2013 and June 2015. RESULTS: There were no cases of DPPB in the CSP group.âConversely, DPPB occurred in 4 patients (1.9â%) after HP, resulting in a significant difference between the CSP and HP groups (0.008â% vs 0â%, P â=â0.02). Propensity score-matching analysis created 402 matched pairs, yielding a significantly higher DPPB rate in the HP group than CSP group (0.02â% vs 0â%, P â=â0.04). However, significantly more patients in the CSP group had unclear horizontal margins that precluded assessment (83 vs 38 cases, P â<â0.001). The retrieval failure rate was significantly higher in the CSP group than in the HP group (3â% vs 0.7â%, P â=â0.01). CONCLUSIONS: DPPB was less frequent with CSP than HP, as selected by the propensity score-matching model. Our findings indicate that CSP is recommended polypectomy in daily clinical setting. However, special care should be taken during polyp retrieval and horizontal margin assessment, and these issues could be taken into account in follow-up after CSP.
RESUMO
AIMS: To investigate variables before sorafenib therapy on the clinical outcomes in hepatocellular carcinoma (HCC) patients receiving sorafenib and to further assess and compare the predictive performance of continuous parameters using time-dependent receiver operating characteristics (ROC) analysis. PATIENTS AND METHODS: A total of 225 HCC patients were analyzed. We retrospectively examined factors related to overall survival (OS) and progression free survival (PFS) using univariate and multivariate analyses. Subsequently, we performed time-dependent ROC analysis of continuous parameters which were significant in the multivariate analysis in terms of OS and PFS. Total sum of area under the ROC in all time points (defined as TAAT score) in each case was calculated. RESULTS: Our cohort included 175 male and 50 female patients (median age, 72 years) and included 158 Child-Pugh A and 67 Child-Pugh B patients. The median OS time was 0.68 years, while the median PFS time was 0.24 years. On multivariate analysis, gender, body mass index (BMI), Child-Pugh classification, extrahepatic metastases, tumor burden, aspartate aminotransferase (AST) and alpha-fetoprotein (AFP) were identified as significant predictors of OS and ECOG-performance status, Child-Pugh classification and extrahepatic metastases were identified as significant predictors of PFS. Among three continuous variables (i.e., BMI, AST and AFP), AFP had the highest TAAT score for the entire cohort. In subgroup analyses, AFP had the highest TAAT score except for Child-Pugh B and female among three continuous variables. CONCLUSION: In continuous variables, AFP could have higher predictive accuracy for survival in HCC patients undergoing sorafenib therapy.
RESUMO
AIMS: We sought to compare the effects of FIB-4 index and aspartate aminotransferase to platelet ratio index (APRI) on hepatocellular carcinoma (HCC) incidence in chronic hepatitis B (CHB) patients undergoing entecavir (ETV) therapy. PATIENT AND METHODS: A total of 338 nucleosides analogue therapy naïve CHB patients initially treated with ETV were analyzed. The optimal cutoff points in each continuous variable were determined by receiver operating curve (ROC) analysis. The effects of FIB-4 index and APRI on HCC incidence were compared using time-dependent ROC analysis and factors linked to HCC incidence were also examined using univariate and multivariate analyses. RESULTS: There were 215 males and 123 females with the median age of 52 years and the median baseline HBV-DNA level of 6.6 log copies/ml. The median follow-up interval after the initiation of ETV therapy was 4.99 years. During the follow-up period, 33 patients (9.8%) developed HCC. The 3-, 5- 7-year cumulative HCC incidence rates in all cases were 4.4%, 9.2% and 13.5%, respectively. In the multivariate analysis, FIB-4 index revealed to be an independent predictor associated with HCC incidence, while APRI was not. In the time-dependent ROC analyses for all cases and for all subgroups analyses stratified by viral status or cirrhosis status, all area under the ROCs in each time point (2-, 3-, 4-, 5-, 6-, and 7-year) of FIB-4 index were higher than those of APRI. CONCLUSION: FIB-4 index rather than APRI can be a useful predictor associated with HCC development for CHB patients undergoing ETV therapy.
RESUMO
We created a model to predict the development of liver carcinogenesis in patients with chronic hepatitis B (CHB) undergoing entecavir (ETV) therapy and to validate the accuracy using an independent dataset.A total of 328 CHB subjects were analyzed. Subjects were randomly assigned into 2 groups: the training group (n = 164) and the validation group (n = 164). Using data from the training group, we built a predictive model for liver carcinogenesis by performing univariate and multivariate analyses using variables associated with liver carcinogenesis. We subsequently assessed the applicability of the constructed model in the validation group.The median (range) follow-up periods in the training and the validation groups were 5.03 years (1.03-9.98) and 4.84 years (1.10-9.97), respectively. The proportion of hepatitis B virus-DNA at 24 weeks <1.9âlogâIU/mL in the training group was 70.7% (116/164), while that in the validation group was 71.3% (117/164). For the entire cohort (n = 328), the median alpha-fetoprotein (AFP) value at 24 weeks (3.45âng/mL; range, 0.9-102.7âng/mL) significantly decreased compared to the baseline values (5.55âng/mL; range, 0.9-1039.5âng/mL), while the median alanine aminotransferase (ALT) value at 24 weeks (24âIU/mL; range, 6-251âIU/mL) also significantly decreased compared to baseline values (57âIU/mL; range, 7-1450âIU/mL). During the observation period, hepatocellular carcinoma (HCC) developed in 15 (9.1%) patients in the training group and in 17 (10.4%) patients in the validation group. The 3- and 5-year cumulative HCC incidence rates in the entire cohort were 4.48% and 9.52%, respectively. In the multivariate analysis of the training group, age ≥54 years (P = 0.0273), ALT level at 24 weeks (P = 0.0456), and AFP at 24 weeks (P = 0.0485) were found to be significant predictors linked to HCC. Using these independent predictors, the risk for HCC development was well stratified in the validation group (overall significance, Pâ<â0.0001). Similar results were observed in subgroup analyses of patients with or without cirrhosis and HBe antigen positivity.In conclusion, our predictive model was well verified; hence, it may be a promising model for the prediction of the development of liver carcinogenesis in CHB patients undergoing ETV therapy.

To the best of our knowledge, none of the prognostic staging systems for hepatocellular carcinoma (HCC) patients who underwent sorafenib therapy is universally adopted or preferred. In the present study, we aimed to compare prognostic ability among five prognostic systems, including the Japan Integrated Staging (JIS) system, the Barcelona Clinic Liver Cancer classification system, the tumor-node-metastasis classification system, the Cancer of the Liver Italian Program scoring system and the Chinese University Prognostic Index (CUPI) scoring system for HCC patients who received sorafenib therapy. A total of 143 HCC patients treated with sorafenib were analysed. We compared prognostic ability among the five prognostic systems using the likelihood ratio (LR) χ2 test, linear trend χ2 test and concordance index (c-index). Our cohort included 114 men and 29 women. The median patient age was 71 years (range, 45-89 years). A total of 102 patients were classified as Child-Pugh A and 41 as Child-Pugh B, whereas 31 patients (21.7%) had portal vein invasion and 63 (44.1%) extrahepatic metastases. The median survival time was 6.9 months. In the LR χ2 test, the CUPI scoring system had the highest value (35.804), followed by the JIS system (17.469). In the linear trend χ2 test, the CUPI scoring system had the highest value (17.523), followed by the JIS system (15.819). In addition, the JIS system had the highest value in the 6-month c-index (0.659) as well as in the 1-year c-index (0.674). However, the CUPI classification system had the lowest value in the 1-year c-index (0.590). In conclusion, the JIS system may be an appropriate staging system for HCC patients undergoing sorafenib therapy.
RESUMO
BACKGROUND AND AIMS: We aimed to investigate the effect of serum sodium level on survival in hepatocellular carcinoma (HCC) patients complicating with liver cirrhosis (LC). METHODS: A total of 1170 HCC patients with LC were analysed. We classified these patients into three groups according to serum sodium level at HCC diagnosis: group A (n=96); serum sodium ≤135 mmol/L, group B (n=520); 135 mmol/L < serum sodium ≤140 mmol/L, group C (n=554); serum sodium >140 mmol/L. We compared the baseline characteristics and overall survival (OS) among these three groups. Furthermore, we examined the factors linked to OS using univariate and multivariate analyses. RESULTS: In our results, decreased baseline serum sodium level was significantly associated with Child-Pugh classification and HCC stage along with several laboratory parameters in groups A, B and C. The median follow-up period was 1.1 years in group A, 2.4 years in group B and 3.3 years in group C. The 1-, 3- and 5-year cumulative OS rates in groups A, B and C were 64.8%, 46.9% and 25.7%, respectively, in group A, 85.5%, 60.5% and 41.1%, respectively, in group B and 90.7%, 66.6% and 48.2%, respectively, in group C (P<0.001). The multivariate analyses showed that Child-Pugh classification (P<0.001), HCC stage (P<0.001), serum sodium (P<0.001), aspartate aminotransferase ≥57 IU/L (P=0.002), alkaline phosphatase ≥348 IU/L (P<0.001), alpha-fetoprotein ≥29.2 ng/mL (P=0.019) and des-γ-carboxy prothrombin ≥55 mAU/mL (P<0.001) were significant independent predictors linked to OS. CONCLUSION: Lower serum sodium concentration is a useful predictor in HCC patients complicating with LC.
RESUMO
The present study examined the prognostic ability of our proposed performance status combined Japan Integrated Staging (PS-JIS) system in hepatocellular carcinoma (HCC) patients with liver cirrhosis (LC) comparing with other four prognostic systems including original JIS system, the Barcelona Clinic Liver Cancer classification system, TNM classification system and the Cancer of the Liver Italian Program (CLIP) scoring system. A total of 1,170 HCC patients complicated with LC were analysed. The disease was staged for all analysed patients by means of the five staging systems. The cumulative overall survival (OS) rate was calculated by Kaplan-Meier method and tested by log-rank test. We also examined prognostic factors associated with OS using univariate and multivariate analyses and compared the prognostic ability in each prognostic system using concordance index (c-index) at 1-, 3- and 5-year time-points. Overall significance in each prognostic system was P<0.001. In the multivariate analyses, tumor number, Child-Pugh classification, PS, initial treatment modality and several laboratory parameters were significant independent predictors linked to OS. For all cases, in each time-point, the c-index of PS-JIS system was the highest among five staging systems (0.847, 0.816 and 0.808, respectively), indicating that PS-JIS system has the best predictability among these staging systems. According to subgroup analyses stratified by initial treatment modality, in patients treated with surgical resection (n=205), CLIP scoring system had the highest c-index at every time-point, whereas in patients treated with percutaneous ablative therapies (n=632) at 3- and 5-year time-point and in those with transcatheter arterial therapies (n=281) at every time-point, the c-index of PS-JIS system was the highest. In conclusion, the proposed PS-JIS score can be a useful prognostic system for HCC patients complicated with liver cirrhosis.

BACKGROUND AND AIMS: The aims of our study were to elucidate the relationship between baseline characteristics of hepatocellular carcinoma (HCC) patients complicating with liver cirrhosis (LC) and performance status (PS) and to investigate the impact of PS on survival in patients with HCC complicating with LC. METHODS: In a total of 1003 patients diagnosed with HCC complicating with LC, we divided into two groups of PS ≥1 (n=251) and PS 0 (n=752) as evaluated by using the Eastern Cooperative Oncology Group criteria at the time of HCC diagnosis. Baseline characteristics between these two groups were compared. We also performed univariate and multivariate analyses of factors contributing to overall survival (OS). RESULTS: The median follow-up period was 1.6 years in the PS ≥1 group and 3.1 years in the PS 0 group. The 1-, 3- and 5-year OS rates after each initial therapy for HCC were 90.3%, 67.4% and 49.8%, respectively, in the PS 0 group and 73.4%, 42.0% and 17.7%, respectively, in the PS ≥1 group (P<0.001). A worse PS was significantly associated with age, gender, Child-Pugh classification, HCC stage, Japan Integrated Staging score, initial treatment option for HCC, maximum tumor size, alanine aminotransferase value, hypoalbuminemia, hyperbilirubinemia, renal insufficiency, hyponatremia, prothrombin time prolongation, platelet count and tumor marker level. In multivariate analyses, poorer PS was an independent predictor linked to OS with a hazard ratio of 1.773 (P<0.001). CONCLUSIONS: PS was closely associated with status of HCC patients with LC and could be an important predictor for these populations.
