A phase-I study of second-line S-IROX for unresectable pancreatic cancer after gemcitabine plus nab-paclitaxel failure.

Gemcitabine plus nab-paclitaxel (GnP) and FOLFIRINOX are widely used as first-line regimens for unresectable pancreatic cancer (PC). When GnP therapy is selected, considering patient age or condition, second-line FOLFIRINOX is sometimes difficult to administer owing to its toxicity. This study aimed to determine the recommended dose (RD) of S-IROX (S-1, oxaliplatin, and irinotecan combination) regimens in patients with unresectable PC after first-line GnP failure. This phase-I study used the "3 + 3" dose-escalation design with two dose levels. Patients who failed first-line GnP therapy for unresectable PC were enrolled. Oxaliplatin and irinotecan were administered on day 1, and S-1 was administered orally twice daily on days 1-7, followed by 7 days of rest. The primary endpoints were dose-limiting toxicities (DLTs) and determination of RD. The secondary endpoint was the evaluation of potential antitumor activity. Nine patients received the second-line S-IROX regimen. In level-0 (S-1, 80 mg/m2; oxaliplatin, 85 mg/m2; and irinotecan, 120 mg/m2), no patient experienced DLT; however, one patient experienced grade 3 neutropenia. At level-1 (irinotecan increased to 150 mg/m2), one of six patients experienced DLTs, including G3 diarrhea. The RD was confirmed at the level-1 dose. The response rate, disease control rate, median progression-free survival, and median overall survival were 33.3%, 77.8%, 172 (range:77-422) days, and 414 (101-685) days, respectively. One patient underwent surgery after the second-line S-IROX therapy. Second-line S-IROX treatment was deemed acceptable. The RD was set at level-1 dose (S-1, 80 mg/m2; oxaliplatin, 85 mg/m2; and irinotecan, 150 mg/m2).

Possibility of Cell Block Specimens from Overnight-Stored Bile for Next-Generation Sequencing of Cholangiocarcinoma.

The identification of anticancer therapies using next-generation sequencing (NGS) is necessary for the treatment of cholangiocarcinoma. NGS can be easily performed when cell blocks (CB) are obtained from bile stored overnight. We compared NGS results of paired CB and surgically resected specimens (SRS) from the same cholangiocarcinoma cases. Of the prospectively collected 64 bile CBs from 2018 to 2023, NGS was performed for three cases of cholangiocarcinoma that could be compared with the SRS results. The median numbers of DNA and RNA reads were 95,077,806 [CB] vs. 93,161,788 [SRS] and 22,101,328 [CB] vs. 24,806,180 [SRS], respectively. We evaluated 588 genes and found that almost all genetic alterations were attributed to single-nucleotide variants, insertions/deletions, and multi-nucleotide variants. The coverage rate of variants in SRS by those found in CB was 97.9-99.2%, and the coverage rate of SRS genes by CB genes was 99.6-99.7%. The NGS results of CB fully covered the variants and genetic alterations observed in paired SRS samples. As bile CB is easy to prepare in general hospitals, our results suggest the potential use of bile CB as a novel method for NGS-based evaluation of cholangiocarcinoma.

Diagnosis of pancreatic malignancies using an overnight-stored pancreatic juice cell block specimen.

BACKGROUND AND AIMS: Pancreatic juice cytology is useful for diagnosing pancreatic duct strictures and cystic lesions. However, some cases cannot be diagnosed using cytology. This study aimed to evaluate the utility of the overnight-stored pancreatic juice cell block (CB) method for diagnosing pancreatic disease. METHODS: This retrospective study included 32 patients who presented with pancreatic duct strictures or cystic lesions between 2018 and 2024. The sensitivity, specificity, and accuracy of the CB method and single/multiple pancreatic juice cytology were compared to evaluate the utility of the CB. RESULT: An endoscopic nasopancreatic drainage tube was placed in the main pancreatic duct, and pancreatic juice was collected to create a CB specimen. The median amount of pancreatic juice collected was 180(30-200) mL, and the median number of cytological examinations was three(2-8). Of the 32 cases, 13 were malignant, and 19 were benign (non-malignant). The sensitivity was significantly higher for the CB method (62 %) than for single cytology(15 %, P = 0.0414), and there was no significant difference between CB and multiple cytology(54 %, P = 1.0). The specificity and accuracy were not significantly different between the CB method and single or multiple cytology. When multiple cytology and CB were combined, sensitivity improved to 77 %. The pathological findings of the CB specimens were similar to the surgical specimens, including immunohistochemistry. CONCLUSION: The overnight-stored pancreatic juice CB method was more effective than single cytology, with similar sensitivities to multiple cytology and can also be used for immunohistochemistry. The pancreatic juice CB method is useful for pancreatic juice assessment.

Hepatic inflammation and fibrosis are profiles related to mid-term mortality in biopsy-proven MASLD: A multicenter study in Japan.

AIMS: A multi-stakeholder consensus has proposed MASLD (metabolic dysfunction-associated steatotic liver disease). We aimed to investigate the pathological findings related to the mid-term mortality of patients with biopsy-proven MASLD in Japan. METHODS: We enrolled 1349 patients with biopsy-proven MASLD. The observational period was 8010 person years. We evaluated independent factors associated with mortality in patients with MASLD by Cox regression analysis. We also investigated pathological profiles related to mortality in patients with MASLD using data-mining analysis. RESULTS: The prevalence of MASH and stage 3/4 fibrosis was observed in 65.6% and 17.4%, respectively. Forty-five patients with MASLD died. Of these, liver-related events were the most common cause at 40% (n = 18), followed by extrahepatic malignancies at 26.7% (n = 12). Grade 2/3 lobular inflammation and stage 3/4 fibrosis had a 1.9-fold and 1.8-fold risk of mortality, respectively. In the decision-tree analysis, the profiles with the worst prognosis were characterised by Grade 2/3 hepatic inflammation, along with advanced ballooning (grade 1/2) and fibrosis (stage 3/4). This profile showed a mortality at 8.3%. Furthermore, the random forest analysis identified that hepatic fibrosis and inflammation were the first and second responsible factors for the mid-term prognosis of patients with MASLD. CONCLUSIONS: In patients with biopsy-proven MASLD, the prevalence of MASH and advanced fibrosis was approximately 65% and 20%, respectively. The leading cause of mortality was liver-related events. Hepatic inflammation and fibrosis were significant factors influencing mid-term mortality. These findings highlight the importance of targeting inflammation and fibrosis in the management of patients with MASLD.

Validation study of age-independent fibrosis score (Fibrosis-3 index) in patients with metabolic dysfunction-associated steatotic liver disease.

BACKGROUND AND AIMS: Because the accuracy of the Fibrosis-4 (FIB-4) index for predicting liver fibrosis changes with age, the need for different cut-offs in various age groups has frequently been discussed. We developed the age-independent score, the Fibrosis-3 (FIB-3) index, and have shown its usefulness in patients with metabolic dysfunction-associated steatotic liver disease (MASLD). This study aimed to validate the diagnostic ability of the FIB-3 index to predict fibrosis progression using a large new patient cohort. METHODS: The ability of the FIB-3 index to predict liver fibrosis was analyzed by comparing it with that of the FIB-4 index using data from 1398 patients with MASLD enrolled in the Asia-based clinical outcome NAFLD study. RESULTS: The areas under the receiver operating characteristic curves for predicting fibrosis stage F3 or higher were not different between the FIB-3 and FIB-4 indices in the entire cohort. Using the single ideal cut-offs of the indices (3.41 for FIB-3 index and 2.01 for FIB-4 index), the predictive accuracy of the FIB-3 index was not significantly different from that of the FIB-4 index among patients aged <60 years; however, the accuracy of the FIB-3 index was significantly higher than that of the FIB-4 index in those aged ≥60 years (0.645 and 0.529, respectively; p < 0.0001). CONCLUSION: The high ability of the FIB-3 index with a single cut-off to predict liver fibrosis in patients with MASLD was confirmed. The FIB-3 index could serve as a useful tool for assessing liver fibrosis regardless of age.

Evaluating optimal bilateral biliary stenting in endoscopic reintervention after initial plastic stent dysfunction for unresectable malignant hilar biliary obstruction: Retrospective cross-sectional study.

OBJECTIVES: The placement of plastic stents (PS), including intraductal PS (IS), is useful in patients with unresectable malignant hilar biliary obstruction (UMHBO) because of patency and ease of endoscopic reintervention (ERI). However, the optimal stent replacement method for PS remains unclear. METHODS: This retrospective study included 322 patients with UMHBO. Among them, 146 received PS placement as initial drainage (across-the-papilla PS [aPS], 54; IS, 92), whereas 75 required ERI. Eight bilateral aPS, 21 bilateral IS, and 17 bilateral self-expandable metallic stent (SEMS) placements met the inclusion criteria. Rates of technical and clinical success, adverse events, recurrent biliary obstruction (RBO), time to RBO (TRBO), overall survival, and secondary ERI were compared. RESULTS: There were no significant intergroup differences in rates of technical or clinical success, adverse events, RBO occurrence, or overall survival. The median TRBO was significantly shorter in the aPS group (47 days) than IS (91 days; P = 0.0196) and SEMS (143 days; P < 0.01) groups. Median TRBO did not differ significantly between the IS and SEMS groups (P = 0.44). On Cox multivariate analysis, the aPS group had the shortest stent patency (hazard ratio 2.67 [95% confidence interval 1.05-6.76], P = 0.038). For secondary ERI, the median endoscopic procedure time was significantly shorter in the IS (22 min) vs. SEMS (40 min) group (P = 0.034). CONCLUSIONS: Bilateral IS and SEMS placement featured prolonged patency after first ERI. Because bilateral IS placement is faster than SEMS placement and IS can be removed during secondary ERI, it may be a good option for first ERI.

Prognosis of biopsy-confirmed metabolic dysfunction- associated steatotic liver disease: A sub-analysis of the CLIONE study.

BACKGROUND/AIMS: Metabolic dysfunction-associated steatotic liver disease (MASLD) was recently proposed as an alternative disease concept to nonalcoholic fatty liver disease (NAFLD). We aimed to investigate the prognosis of patients with biopsy-confirmed MASLD using data from a multicenter study. METHODS: This was a sub-analysis of the Clinical Outcome Nonalcoholic Fatty Liver Disease (CLIONE) study that included 1,398 patients with NAFLD. Liver biopsy specimens were pathologically diagnosed and histologically scored using the NASH Clinical Research Network system, the FLIP algorithm, and the SAF score. Patients who met at least one cardiometabolic criterion were diagnosed with MASLD. RESULTS: Approximately 99% of cases (n=1,381) were classified as MASLD. Patients with no cardiometabolic risk (n=17) had a significantly lower BMI than patients with MASLD (20.9 kg/m2 vs. 28.0 kg/m2, P<0.001), in addition to significantly lower levels of inflammation, ballooning, NAFLD activity score, and fibrosis stage based on liver histology. These 17 patients had a median follow-up of 5.9 years, equivalent to 115 person-years, with no deaths, liver-related events, cardiovascular events, or extrahepatic cancers. The results showed that the prognosis for pure MASLD was similar to that for the original CLIONE cohort, with 47 deaths and one patient who underwent orthotopic liver transplantation. The leading cause of death was extrahepatic cancer (n=10), while the leading causes of liver-related death were liver failure (n=9), hepatocellular carcinoma (n=8), and cholangiocarcinoma (n=4). CONCLUSION: Approximately 99% of NAFLD cases were considered MASLD based on the 2023 liver disease nomenclature. The NAFLD-only group, which is not encompassed by MASLD, had a relatively mild histopathologic severity and a favorable prognosis. Consequently, the prognosis of MASLD is similar to that previously reported for NAFLD.

Pancreatic Metastases from Renal Cell Carcinoma Showing Atypical Imaging Findings.

A 59-year-old man receiving sunitinib chemotherapy for postoperative recurrence of renal cell carcinoma (RCC) metastases was found to have multiple metastases on contrast-enhanced computed tomography (CECT). CECT revealed a typical hyperdense enhanced nodule in the arterial phase of the stomach and head and tail of the pancreas. However, in the uncinate process of the pancreas, CECT revealed an atypical image and a hypodense enhanced nodule in each phase. Both lesions were finally pathologically diagnosed as clear cell carcinoma. Treatment-modified pancreatic metastases from RCC may present with nonspecific images; therefore, caution is required when deciding on treatment strategies.

The Usefulness and Reliability of Coagrasper for Artery Bleeding during Endoscopic Necrosectomy.

Although endoscopic necrosectomy (EN) is a less invasive therapy for walled-off necrosis (WON), arterial bleeding can occur during EN. A 60-year-old man with infected WON underwent the EN procedure. During EN, the artery in the WON cavity was injured. As the artery was directly visible, we grasped it using a Coagrasper and coagulated the bleeding point. However, the bleeding was aggravated after coagulation owing to an extension of the vessel damage. The entire vessel was grasped, and complete hemostasis was achieved. The Coagrasper is useful for managing arterial bleeding; however, it should be employed only on the basis of its characteristics and in suitable scenarios.

The evaluation of bilateral stenting using braided or laser-cut self-expandable metallic stent for malignant hilar biliary obstruction.

OBJECTIVES: Bilateral self-expandable metallic stent (SEMS) placement for unresectable malignant hilar biliary obstruction (UMHBO) is an effective option for biliary drainage with long-term stent patency. Laser-cut and braided SEMS can be used for bilateral SEMS placement. This study aimed to clarify any differences in the clinical features and proper use of the laser-cut and braided SEMS placement using the stent-in-stent method for UMHBO. METHODS: In this study, 78 patients who underwent bilateral stent-in-stent SEMS placement for UMHBO were included. The patients were divided into the laser-cut (n = 33) and braided groups (n = 45). Both groups were compared for technical and clinical success, adverse events (AEs), time to recurrent biliary obstruction (TRBO), overall survival, and endoscopic reintervention (ERI). RESULTS: There were no significant differences in technical and clinical success rates (laser-cut vs. braided group, 97% vs. 95.6%, P = 1.0), AEs (21.2% vs. 15.6%. P = 0.56), median TRBO (242 days vs. 140 days, P = 0.36), and median overall survival (654 days vs. 675 days, P = 0.58). ERI was required in 15 patients in the laser-cut group and in 20 patients in the braided group. The technical and clinical success rates of ERI (60% vs. 85%) were not significantly different (P = 0.13); however, the median ERI procedure time was significantly longer in the laser-cut group (38 min) than in the braided group (22 min; P = 0.02). CONCLUSION: No significant difference in initial SEMS placement was noted between the laser-cut and braided groups; however, the laser-cut group required a longer ERI procedure time than that required by the braided group. The use of braided SEMS may be a convenient option for ERI.

Comparison of 19-gauge conventional and Franseen needles for the diagnosis of lymphadenopathy and classification of malignant lymphoma using endoscopic ultrasound fine-needle aspiration.

Background/Aims: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) using a 19-gauge needle is an efficient sampling method for the diagnosis of lymphadenopathy. This study compared 19-gauge conventional and Franseen needles for the diagnosis of lymphadenopathy and classification of malignant lymphoma (ML). Methods: Patient characteristics, number of needle passes, puncture route, sensitivity, specificity, and accuracy of cytology/histology for lymphadenopathy were analyzed in patients diagnosed with lymphadenopathy by EUS-FNA using conventional or Franseen needles. Results: Between 2012 and 2022, 146 patients met the inclusion criteria (conventional [n=70] and Franseen [n=76]). The median number of needle passes was significantly lower in the conventional group than in the Franseen group (3 [1-6] vs. 4 [1-6], p=0.023). There were no significant differences in cytological/histological diagnoses between the two groups. For ML, the immunohistochemical evaluation rate, sensitivity of flow cytometry, and cytogenetic assessment were not significantly different in either group. Bleeding adverse events (AEs) were observed in three patients in the Franseen group. Conclusions: Both the 19-gauge conventional and Franseen needles showed high accuracy in lymphadenopathy and ML classification. Considering sufficient tissue collection and the avoidance of AEs, the use of 19-gauge conventional needles seems to be a good option for the diagnosis of lymphadenopathy.

Identification of clinical phenotypes associated with poor prognosis in patients with nonalcoholic fatty liver disease via unsupervised machine learning.

BACKGROUND AND AIMS: Both fibrosis status and body weight are important for assessing prognosis in nonalcoholic fatty liver disease (NAFLD). The aim of this study was to identify population clusters for specific clinical outcomes based on fibrosis-4 (FIB-4) index and body mass index (BMI) using an unsupervised machine learning method. METHODS: We conducted a multicenter study of 1335 biopsy-proven NAFLD patients from Japan. Using the Gaussian mixture model to divide the cohort into clusters based on FIB-4 index and BMI, we investigated prognosis for these clusters. RESULTS: The cohort consisted of 223 cases (16.0%) with advanced fibrosis (F3-4) as assessed from liver biopsy. Median values of BMI and FIB-4 index were 27.3 kg/m2 and 1.67. The patients were divided into four clusters by Bayesian information criterion, and all-cause mortality was highest in cluster d, followed by cluster b (P = 0.001). Regarding the characteristics of each cluster, clusters d and b presented a high FIB-4 index (median 5.23 and 2.23), cluster a presented the lowest FIB-4 index (median 0.78), and cluster c was associated with moderate FIB-4 level (median 1.30) and highest BMI (median 34.3 kg/m2 ). Clusters a and c had lower mortality rates than clusters b and d. However, all-cause of death in clusters a and c was unrelated to liver disease. CONCLUSIONS: Our clustering approach found that the FIB-4 index is an important predictor of mortality in NAFLD patients regardless of BMI. Additionally, non-liver-related diseases were identified as the causes of death in NAFLD patients with low FIB-4 index.

Association of Serum Albumin Levels and Long-Term Prognosis in Patients with Biopsy-Confirmed Nonalcoholic Fatty Liver Disease.

The relationship between baseline serum albumin level and long-term prognosis of patients with nonalcoholic fatty liver disease (NAFLD) remains unknown. This is a sub-analysis of the CLIONE (Clinical Outcome Nonalcoholic Fatty Liver Disease) study. The main outcomes were: death or orthotopic liver transplantation (OLT), liver-related death, and liver-related events (hepatocellular carcinoma [HCC], decompensated cirrhosis, and gastroesophageal varices/bleeding). 1383 Japanese patients with biopsy-confirmed NAFLD were analyzed. They were divided into 3 groups based on serum albumin: high (>4.0 g/dL), intermediate (3.5-4.0 g/dL), and low (<3.5 g/dL). Unadjusted hazard ratio [HR] of the intermediate albumin group, compared with the high albumin group, were 3.6 for death or OLT, 11.2 for liver-related death, 4.6 for HCC, 8.2 for decompensated cirrhosis, and 6.2 for gastroesophageal varices (all risks were statistically significant). After adjusting confounding factors, albumin remained significantly associated with death or OLT (intermediate vs. high albumin group: HR 3.06, 95% confidence interval [CI] 1.59-5.91, p < 0.001; low vs. high albumin group: HR 22.9, 95% CI 8.21-63.9, p < 0.001). Among biopsy-confirmed NAFLD patients, those with intermediate or low serum albumin had a significantly higher risk of death or OLT than those with high serum albumin.

Utility of bilateral intraductal plastic stent for malignant hilar biliary obstruction compared with bilateral self-expandable metal stent: a propensity score-matched cohort analysis.

BACKGROUND AND AIMS: Intraductal plastic stent (IS) placement for unresectable malignant hilar biliary obstruction (UMHBO) is an effective option for biliary drainage. However, the effectiveness of bilateral IS placement compared with bilateral self-expandable metal stent (SEMS) placement remains unclear. METHODS: Overall, 301 patients with UMHBO were enrolled; 38 patients underwent bilateral IS placement (IS group) and 38 patients underwent SEMS placement (SEMS group) in the propensity score-based cohort. Both groups were compared for technical and clinical success, adverse events (AEs), recurrent biliary obstruction (RBO), time to RBO (TRBO), overall survival (OS), and endoscopic reintervention (ERI). RESULTS: No significant differences were observed between the groups regarding technical and clinical success, AEs and RBO occurrence rates, TRBO, or OS. The median initial endoscopic procedure time was significantly shorter in the IS group (23 vs 49 minutes, P < .01). ERI was performed on 20 and 19 patients in the IS and SEMS groups, respectively. The median ERI procedure time was significantly shorter in the IS group (22 vs 35 minutes, P = .04). Median TRBO after ERI with plastic stent placement tended to be longer in the IS group (306 vs 56 days, P = .068). A Cox multivariate analysis showed that the IS group was the significant related factor for TRBO after ERI (hazard ratio, .31; 95% confidence interval, .25-.82; P = .035). CONCLUSIONS: Bilateral IS placement can reduce the duration of the endoscopic procedure and provide sufficient stent patency both initially and after ERI stent placement, and the stents are removable. Bilateral IS placement is considered a good option for initial UMHBO drainage. (Clinical trial registration number: UMIN000050546.).

Agile 3+ and Agile 4, noninvasive tests for liver fibrosis, are excellent formulae to predict liver-related events in nonalcoholic fatty liver disease.

AIM: The noninvasive tests (NITs) Agile 3+ and Agile 4 effectively identify patients with nonalcoholic fatty liver disease (NAFLD) complicated with advanced fibrosis (F3-4) and cirrhosis (F4), respectively. Little information is available on associations between Agile scores and intra-/extrahepatic events. The aim of this study was to determine the predictive performance of Agile scores for intra-/extrahepatic events in Asian patients with biopsy-proven NAFLD. METHODS: We undertook a retrospective multicenter cohort study to investigate associations between intra-/extrahepatic events and two Agile scores, Agile 3+ and Agile 4. The scores were obtained by combining clinical parameters and liver stiffness measurement using transient elastography. RESULTS: Among 403 enrolled patients, 11 had liver-related events (LREs), including seven with hepatocellular carcinoma (HCC). The incidence of LREs and HCC showed a stepwise increase in the advanced fibrosis group (F3-4), Agile 3+ rule-in (F3-4, highly suspected), and Agile 4 rule-in (F4, highly suspected) groups, compared to their counterparts. Hazard ratios for LREs in the advanced fibrosis group, Agile 3+ rule-in, and Agile 4 rule-in groups were 4.05 (p = 0.03), 23.5 (p = 0.003), and 45.5 (p < 0.001), respectively. The predictive performance results for Agile 3+ and Agile 4 were 0.780 and 0.866, respectively, which were higher than for fibrosis (0.595). Unlike for LREs, Agile scores failed to identify patients with extrahepatic events, including cardiovascular events and extrahepatic cancer. CONCLUSIONS: Agile 3+ and Agile 4 scores are excellent NITs for predicting LREs in patients with NAFLD, possibly without histological assessment.

Prediction of Liver-Related Events With a Combination of Liver Stiffness Measurements and Controlled Attenuation Parameters in Japanese Patients With Biopsy-Proven Non-alcoholic Fatty Liver Disease.

OBJECTIVE: Liver stiffness measurements (LSMs) and controlled attenuation parameters (CAPs) obtained using vibration-controlled transient elastography (VCTE) are recognized non-invasive methods of assessing liver histology. The usefulness of CAP for predicting liver-related events (LREs: hepatocellular carcinoma, decompensation, bleeding varices) is not well understood worldwide. Our aim was to re-evaluate the cutoff values of LSM/CAP in Japan and to examine whether LSM/CAP can predict LRE. METHODS: Japanese NAFLD patients (n = 403) who underwent both liver biopsy and VCTE were enrolled. We determined optimal cutoff values of LSM/CAP diagnoses for fibrosis stage and steatosis grade and investigated their clinical outcome based on LSM/CAP values. RESULTS: The LSM cutoff values for F1 to F4 are 7.1, 7.9, 10.0 and 20.2 kPa, and the CAP cutoff values for S1 to S3 are 230, 282 and 320 dB/m. During a median follow-up of 2.7 y (range: 0.0-12.5 y), 11 patients developed LREs. The incidence of LREs in the LSM Hi (≥8.7) group was significantly higher than that in the LSM Lo (<8.7) group (p = 0.003), and the incidence in the CAP Lo (<295) group was higher than that in CAP Hi (≥295) group (p = 0.018). Considering LSM and CAP together, the risk of LRE was higher in the LSM Hi CAP Lo group than in the LSM Hi CAP Hi group (p = 0.03). CONCLUSION: We set LSM/CAP cutoff values to diagnose liver fibrosis and steatosis in Japan. Our study determined that NAFLD patients with high LSM and low CAP values are at high risk for LREs.

Noninvasive tests predict liver-related events and mortality in patients with nonalcoholic fatty liver disease: sub-analysis of the CLIONE-Asia study.

BACKGROUND AND AIMS: Noninvasive tests (NITs) have prognostic potential, but whether NITs are comparable with liver biopsy is unclear. This study aimed to examine the prognostic accuracy of NITs for liver-related mortality (LRM) and events (LREs) in patients with biopsy-proven nonalcoholic fatty liver disease (NAFLD). METHODS: We investigated 1313 patients with NAFLD. Patients were assigned to low-risk, indeterminate-risk, and high-risk groups using conventional cutoff values of each FIB-4 and NAFLD fibrosis score (NFS) and to stage 0-2 and stage 3-4 groups using the fibrosis stage. Survival and Cox regression analyses of the prognostic potential of NITs for LRM/LREs were conducted. RESULTS: During a median follow-up of 4.5 years, regarding to FIB-4, the incidence rate (/1000 person-years) in the low risk was zero for LRM and 0.5 for LREs. In contrast, the rate in stage 0-2 was 1.3 for LRM and 2.8 for LRE. The adjusted hazard ratios (aHRs) for LREs in the high risk compared with the low risk were 32.85 (P < 0.01). The aHRs in stage 3-4 compared with stage 0-2 were 2.68 (P = 0.02) for LREs and 2.26 (P = 0.582) for LRM. In the same fibrosis stage, the incidence of LRM/LREs was more frequent with a higher risk stratification. The same trend was observed for NFS. CONCLUSIONS: NITs accurately predict LRM and LREs as well as a liver biopsy in Japanese patients with NAFLD. Patients in the low risk may not require close follow-up for at least 5 years. The simple NITs could be an acceptable alternative method to performing a liver biopsy for the prognosis of NAFLD.

Multicenter, retrospective, cohort study shows platelet counts predict hepatocellular carcinoma development in patients with nonalcoholic fatty liver disease.

AIM: Impacts of platelet counts at the time of liver biopsy on hepatocellular carcinoma (HCC) development in patients with nonalcoholic fatty liver disease (NAFLD) remain unknown. The aim of this study was to investigate the prognostic value of platelet counts in patients with biopsy-confirmed NAFLD using data from a multicenter study. METHODS: One thousand three hundred ninety-eight patients were included in this subanalysis of the CLIONE (Clinical Outcome Nonalcoholic Fatty Liver Disease) in Asia study. Liver biopsy specimens were pathologically diagnosed, and histologically scored using the NASH Clinical Research Network system. Demographic, clinical, laboratory, and pathological data were collected. RESULTS: During a median follow-up period of 4.6 years (range, 0.3-21.6 years), which corresponds to 8874 person-years, 37 patients developed HCC. Using a cut-off baseline platelet count of 192 × 109/L, the lower platelet group had a higher HCC rate than the higher platelet group (6.7% vs. 0.4%; p < 0.001). This cut-off value significantly stratified the event-free rate for HCC. Lower platelet counts were associated with an increased risk of HCC development. Relative to patients with platelet counts of 192 × 109/L, patients with platelet counts of 100 × 109/L had an unadjusted hazard ratio (HR) for HCC development of 7.37 (95% confidence interval [CI], 3.81-14.2) and an adjusted HR of 11.2 (95% CI, 3.81-32.7; p < 0.001), adjusting for age, sex, NASH, and diabetes. CONCLUSIONS: Baseline platelet counts of 192 × 109/L and lower are associated with a higher risk of developing HCC in patients with biopsy-confirmed NAFLD and require active surveillance.

Clinical Outcomes in Biopsy-Proven Nonalcoholic Fatty Liver Disease Patients: A Multicenter Registry-based Cohort Study.

BACKGROUND & AIMS: There are no detailed reports of clinical outcomes in Asian patients with nonalcoholic fatty liver disease (NAFLD) who undergo liver biopsy. We aimed to investigate the clinical outcomes of a large cohort of Asian patients with biopsy-proven NAFLD and evaluate the specific effects of nonalcoholic steatohepatitis and fibrosis stage. METHODS: This multicenter registry-based retrospective cohort study, called the CLIONE (Clinical Outcome Nonalcoholic Fatty Liver Disease) in Asia, included 1398 patients. RESULTS: The median follow-up period was 4.6 years (range, 0.3-21.6 years), representing a total of 8874 person-years of follow-up. During that time, 47 patients died, and 1 patient underwent orthotopic liver transplantation. The leading cause of death was nonhepatic cancer (n = 10). The leading causes of liver-related death were liver failure (n = 9), hepatocellular carcinoma (HCC) (n = 8), and cholangiocellular carcinoma (n = 4). During follow-up, 37 patients developed HCC, 31 developed cardiovascular disease, and 68 developed nonhepatic cancer (mainly breast, stomach, and colon/rectum). Among our cohort of patients with NAFLD, liver-specific mortality was 2.34/1000 person-years (95% confidence interval [CI], 1.52-3.58), overall mortality was 5.34/1000 person-years (95% CI, 4.02-7.08), and HCC incidence was 4.17/1000 person-years (95% CI, 3.02-5.75). Liver fibrosis was independently associated with liver-related events but not overall mortality. CONCLUSIONS: Liver-related mortality was the leading cause of mortality in Asian patients with biopsy-confirmed NAFLD. Although fibrosis stage was independently associated with liver-related events, it was not associated with overall mortality after adjusting for confounders, such as histologic features of steatohepatitis.
