RESUMEN

BACKGROUND AND AIM: Rapidly aging societies have become a major issue worldwide including Japan. This study aimed to elucidate relative changes in the characteristics of inpatients in Japan related to this issue. METHODS: A total of 23 835 Japanese inpatients treated from 2010 to 2021 were enrolled (2010-2013, period I; 2014-2017, period II; 2018-2021, period III). Changes in clinical features were retrospectively analyzed based on ICD-10 diagnosis data. RESULTS: The percentage of patients aged over 75 years increased over time (period I, 38.0%; II, 39.5%, III, 41.4%). Emergency admissions comprised 27.5% of all in period I, which increased to 43.2% in period II and again to 44.5% in period III (P < 0.001). In period I, gastrointestinal disease, liver disease, pancreatic-biliary disease, and other disease types were noted in 47.4%, 29.5%, 19.2%, and 3.9%, respectively, while those values were 44.0%, 18.0%, 33.9%, and 4.1%, respectively, in period III (P < 0.001). The frequency of liver disease decreased by approximately 0.6-fold from periods I to III, while that of biliary-pancreatic disease increased by approximately 1.8-fold during that time. Both percentage and actual numbers of patients with biliary-pancreatic disease increased during the examined periods. Analysis of changes in the proportion of organs affected by malignancy during periods I, II, and III showed a marked increase in cases of biliary-pancreatic malignancy (11.6%, 19.5%, 26.6%, respectively) (P < 0.001). CONCLUSION: In association with the rapidly aging Japanese society, there has been an increasing frequency of biliary-pancreatic disease cases requiring hospitalization for treatment in the west Japan region of Shikoku.

RESUMEN

BACKGROUND/AIM: Unresectable recurrence after curative treatments for hepatocellular carcinoma (HCC) is a life-limited event. Although the IMbrave050 trial (IM050) showed a favorable reduction in recurrence with adjuvant immune-combination chemotherapy, inclusion criteria of the radiofrequency ablation (RFA) group were lower risk than that of the resection group. This study aimed to elucidate the clinical features of patients treated with RFA, which really need adjuvant-chemotherapy. METHODS: From 2000 to 2022, 528 patients with Child-Pugh A and HCC within the Milan criteria (MC), who met the IM050 criteria for RFA and undergone resection or RFA, were enrolled (71 years, HCV:HBV:HBV/HCV:alcohol:others = 337:44:5:53:89, multi-tumor = 138, RFA:resection = 309:219). Unresectable recurrence was defined as beyond the MC. Risk factors for recurrence beyond the MC were retrospectively evaluated. RESULTS: Multivariate Cox-hazard analysis showed HCV-positive (HR 1.49), AFP-L3 > 10% (HR 1.75), and DCP > 100 mAU/mL (HR1.80) as significant prognostic factors for recurrence beyond the MC (each P < 0.05). Summing of positive factors (1 point for each) was used for scoring (AD-ON score), which showed increased positive rates for micro-hepatic vein invasion (score 0:1:2:3 = 0%:1.1%:6.6%:15.8%), micro-portal vein invasion (0:1:2:3 = 2.0%:12.1%:14.1%:31.6%), and poor differentiation (0:1:2:3 = 6.0%:6.7%:15.3%:15.8%) in the resection group associated with a greater score (each P < 0.01). In patients treated with RFA, those with greater AD-ON scores showed shorter time to recurrence beyond the MC, recurrence-free time, and overall survival (score 0:1:2:3 = no-estimation:97:66:23 months, 35:27:20:12 months, and 91:82:67:52 months, respectively, each P < 0.05). CONCLUSION: HCC patients treated by RFA and with a high AD-ON score (≧2) should be considered for aggressive adjuvant-chemotherapy to prolong the period of recurrence beyond the MC.

RESUMEN

INTRODUCTION: For predicting esophagogastric varices (EGVs), the Virtual Baveno VII Consensus Workshop has proposed a combination of liver stiffness determination and platelet count measurement using a FibroScan®. However, FibroScan® is not available at all institutions. The present study aimed to develop a simple method to predict development of EGV using only general blood examination results. MATERIALS AND METHODS: A total of 1,090 hepatocellular carcinoma patients were enrolled, after excluding 956 with major portal vein tumor thrombus (Vp3/Vp4) or without upper gastrointestinal endoscopy examination results available. Those with EGV (≥ grade F2) or a history of treatment for the condition were defined as positive for significant EGV, and then clinical factors were retrospectively evaluated to determine indicators of occurrence. RESULTS: Logistic multivariate analysis showed platelet count (≤12 × 104/µL) (odds ratio [OR] 3.79, p < 0.001), mALBI grade 2a (OR 1.52, p = 0.036), and mALBI 2b or 3 (OR 3.46, p < 0.001) as significant predictive factors. Based on the OR values, platelet count (≤12 × 104/µL) and mALBI grade 2b/3 were each assigned 2 points and mALBI 2a was given 1 point, with the result termed recommendation for EGV screening (REGS) score. Significant EGV occurrence was noted in 2.9% (9/311) of the patients with a REGS score 0, 11.0% (13/118) with a score 1, 19.3% (53/274) with a score 2, 29.5% (39/132) with a score 3, and 38.0% (97/255) with a score 4 (p < 0.001). CONCLUSION: The findings indicate that REGS score can provide useful predictive information for development of significant EGV without the need for special equipment such as a FibroScan®.

RESUMEN

No reports of renal cancer in patients with Wilson's disease (WD) exist. We herein report a 37-year-old Japanese man diagnosed with WD who had been treated with d-penicillamine 9 years prior. Hepatocellular carcinoma had been diagnosed at 36 years old and treated with radiofrequency ablation therapy. One year later, renal cancer and recurrent hepatocellular carcinoma had developed. The hepatocellular carcinoma was treated after renal cancer surgical resection of a clear-cell-type renal cell carcinoma, with iron, rather than copper, deposited on the renal cancer cells. This patient harbored a novel mutation, p. Leu1395Terfs in ATP7B.

RESUMEN

INTRODUCTION: The aMAP score is a prediction model for hepatocellular carcinoma (HCC) risk in chronic hepatitis patients. This study was conducted to elucidate the utility of this model for predicting initial recurrence of HCC in patients within the Milan criteria after undergoing curative treatment. METHODS: Patients with naïve HCC within the Milan criteria (n = 1,020) and treated from January 2000 to August 2022 were enrolled. The cohort was divided into two groups according to the aMAP score (high ≥60, low <60) and then compared for recurrence-free survival (RFS) and overall survival (OS). RESULTS: Comparisons between the high and low groups showed that etiology (HBV:HCV:HBV+HCV:NBNC = 41:79:2:37 vs. 65:589:11:196, p < 0.001), AST (36 vs. 46 IU/L, p < 0.001), and multiple HCC occurrence (15% vs. 22%, p = 0.026) were significantly different. Additionally, median RFS (59.8 vs. 30.9 months; p < 0.001) and median OS (154.1 vs. 83.4 months, p < 0.01) were greater in the low group. As for patients with HCC due to chronic viral hepatitis, there was a significant difference in median RFS between the groups (59.8 vs. 30.6 months, p < 0.001), especially for HCV-positive patients (53.1 vs. 27.2 months, p = 0.002). In patients with HCC due to a nonviral cause, the difference in median RFS between the low (70.9 months) and high (32.0 months) groups was not significant. DISCUSSION: Findings of this retrospective study indicate a significant association of elevated aMAP with worse RFS in patients with HCC caused by chronic viral hepatitis, especially those with HCV. The aMAP score is considered useful to predict not only HCC-carcinogenesis risk but also risk of recurrence following curative treatment.

RESUMEN

PURPOSE: The albumin to globulin ratio (AGR) is a recognized chronic inflammation marker. No evidence regarding the relationship between AGR level and ulcerative colitis (UC) exists. The aim of this study was to evaluate the association between AGR and clinical outcomes among Japanese subjects with UC. METHODS: The study subjects consisted of 273 Japanese individuals with UC. AGR was divided into 4 categories (low, moderate, high, and very high). The definition of complete mucosal healing (MH) was based on the Mayo endoscopic subscore of 0. Clinical remission (CR) was defined as no rectal bleeding and no abnormally high stool frequency (<3 times per day). RESULTS: The percentage of MH was 26.4%. High AGR and very high AGR were significantly positively correlated with CR (adjusted odds ratio [OR], 5.85; 95% confidence interval [CI], 2.52-14.18 and adjusted OR, 4.97; 95% CI, 2.14-12.04) and complete MH (adjusted OR, 4.03; 95% CI, 1.56-11.51 and adjusted OR, 5.22; 95% CI, 1.97-14.89), respectively after adjustment for confounding factors (P for trend=0.001). Only in the low C-reactive protein (CRP) group (≤0.1 mg/dL), very high AGR was significantly positively correlated with complete MH but not CR (adjusted OR, 4.38; 95% CI, 1.06-21.77; P for trend=0.017). In the high CRP group, no correlation between AGR and complete MH was found. CONCLUSION: Among Japanese patients with UC, AGR may be independently positively correlated with complete MH. In particular, among UC patients with low CRP, AGR might be a useful complementary marker for complete MH.

RESUMEN

Background/Aim: The SURF trial showed that surgical resection (SR) and percutaneous ultrasonographic guided radiofrequency ablation (RFA) had equal therapeutic effects for small hepatocellular carcinoma (HCC). However, consensus regarding which treatment is appropriate for initial recurrent early-stage HCC remains lacking. This study aimed to elucidate therapeutic efficacy differences between SR and RFA for initial recurrent early-stage HCC. Materials/Methods: From 2000 to 2021, 371 patients with recurrent early-stage HCC (≤3 cm, ≤3 nodules) after undergoing initial curative treatment with SR or RFA were enrolled (median age 72 years; males 269; Child−Pugh A:B, n = 328:43; SR:RFA, n = 36:335). Recurrence-free survival (RFS) and overall survival (OS) were retrospectively evaluated. Results: Although the median albumin−bilirubin (ALBI) score was better in the SR than the RFA group (−2.90 vs. −2.50, p < 0.01), there were no significant differences between them in regard to RFS (median 28.1 months, 95% CI 23.4−50.0 vs. 22.1 months, 95% CI 19.3−26.2; p = 0.34), OS (78.9 months, 95% CI 49.3­not applicable vs. 71.2 months 95% CI, 61.8−84.7; p = 0.337), or complications (8.3% vs. 9.3%; p = 1.0). In sub-analysis for RFS and OS according to ALBI grade revealed no significant differences between the SR and RFA groups (ALBI 1/2 = 28.2/17.5 vs. 24.0/23.4 months; p = 0.881/0684 and ALBI 1/2 = 78.9/58.9 vs. 115.3/52.6 months, p = 0.651/0.578, respectively). Conclusion: This retrospective study found no significant differences in regard to RFS or OS between patients in the SR and the RFA groups for initial recurrence of early-stage HCC after undergoing curative treatment. These results showing equal therapeutic efficacy of SR and RFA confirm the findings of the SURF trial.

RESUMEN

The incidence of inflammatory bowel disease (IBD) is increasing; hence, effective treatments are warranted. The therapeutic effect of human carbonic anhydrase I (hCA I) in IBD remains unknown. Therefore, we investigated whether oral tolerization to hCA I would induce antigen-specific protection from intestinal inflammation in vivo. Severe combined immunodeficient mice received hCA I, keyhole limpet hemocyanin (KLH), or phosphate-buffered saline (PBS) orally for 7 days. Colons and mesenteric lymph nodes (MLNs) were collected 4 weeks after cell transfer. Additionally, the mechanisms underlying the therapeutic effects were investigated. The comparison between the effects of well-established drugs and hCA I oral administration was investigated. Oral administration of hCA I ameliorated colitis remarkably. hCA I reached the cecum and ameliorated colitis more effectively than mesalazine and similarly to prednisolone. Compared with PBS treatment, hCA I treatment reduced interleukin (IL)-17a, IL-6, and retinoic acid-related orphan receptor gamma t (RORγt) expression in the colon or MLNs; moreover, hCA I markedly reduced IL-6, IL-17, and interferon-gamma (IFN-γ) levels in the MLN. Oral administration of hCA I induced immune tolerance and suppressed colitis in vivo. Thus, hCA I administration could be proposed as a new treatment option for IBD.

RESUMEN

BACKGROUND: A simple serum biomarker for clinical outcome in patients with ulcerative colitis (UC) remains an unmet need. Some studies have shown an association between C-reactive protein (CRP)-albumin ratio (CAR) and prognosis in patients with inflammatory bowel disease (IBD), but evidence regarding the association between CAR and UC remains limited. We evaluated the association between CAR and clinical outcome in Japanese patients with UC. METHODS: Subjects were 273 Japanese patients with UC. Clinical remission was defined as absence of both abnormally high stool frequency (< 3 per day) and rectal bleeding. Mucosal healing (MH) was defined as Mayo endoscopic subscore (MES) 0. Moderate to severe endoscopic activity was defined as MES 2-3. Subjects were divided according to CAR into tertiles (low, moderate, and high). RESULTS: The proportions of patients with clinical remission, MH, and moderate to severe endoscopic activity were 57.9%, 26.0%, and 37.0%, respectively. High CAR was significantly positively associated with moderate to severe endoscopic activity but not MH or clinical remission after adjustment (adjusted odds ratio [OR] 2.18 [95% confidence interval (CI) (1.11-4.35)], p for trend 0.023), but only in patients with long disease duration (> 7 years) (adjusted OR 2.95 [95% CI (1.06-8.79)], p for trend 0.023). CAR was not associated with clinical remission or MH. CONCLUSIONS: CAR may be significantly positively associated with moderate to severe endoscopic activity but not clinical remission or MH in Japanese patients with UC. In patients with long UC duration, CAR might be a useful serum marker for disease activity.

RESUMEN

Background/Aim: For intermediate-stage hepatocellular carcinoma (HCC) (Barcelona Clinic Liver Cancer [BCLC]-B) cases, transarterial chemoembolization (TACE) is recognized as the standard treatment, while systemic therapy is recommended for TACE-unsuitable HCC. However, because the curative potential is not high, this study was conducted to elucidate the potential outcomes of surgical resection (SR) for BCLC-B HCC cases. Materials/Methods: From January 2000 to July 2022, 70 patients with BCLC-B HCC treated with surgery as the initial treatment were enrolled (median age 67.5 years, beyond up-to-7 criteria 44). Forty-five were treated with SR only (SR group), while twenty-five underwent that with complemental radiofrequency ablation (RFA) (Comb group). Recurrence-free survival (RFS) and overall survival (OS) were retrospectively evaluated in both groups. Results: The median albumin−bilirubin (ALBI) score was better in the SR as compared with the Comb group (−2.74 vs. −2.52, p = 0.02), while there were no significant differences between them for median RFS (17.7 vs. 13.1 months; p = 0.70) or median OS (66.6 vs. 72.0 months p = 0.54). As for those beyond up-to-7 criteria, there were no significant differences for median RFS (18.2 vs. 13.0 months; p = 0.36) or median OS (66.5 vs. 72.0 months; p = 0.57). An acceptable five-year cumulative survival rate (>50%) was obtained in both groups (54% vs. 64%). Conclusion: This retrospective study found no significant differences for RFS or OS between the present SR and Comb groups with BCLC-B HCC. When possible to perform, the outcome of SR for BCLC-B is favorable, with a five-year survival rate greater than 50%.

RESUMEN

The small intestinal mucosa-associated microbiota (MAM) can potentially impact the etiology of primary biliary cholangitis (PBC). Herein, we investigate the MAM profile to determine its association with liver pathology in patients with PBC. Thirty-four patients with PBC and 21 healthy controls who underwent colonoscopy at our hospital were enrolled in our study. We performed 16S ribosomal RNA gene sequencing of MAM samples obtained from the mucosa of the terminal ileum and examined the relationship between the abundance of ileal MAM and chronic nonsuppurative destructive cholangitis using liver specimens from patients with PBC. There was a significant reduction in microbial diversity within individuals with PBC (P = 0.039). Dysbiosis of ileal MAM was observed in patients with PBC, with a characteristic overgrowth of Sphingomonadaceae and Pseudomonas. Multivariate analysis showed that the overgrowth of Sphingomonadaceae and Pseudomonas is an independent association factor for PBC (P = 0.0429, P = 0.026). Moreover, the abundance of Sphingomonadaceae was associated with chronic nonsuppurative destructive cholangitis in PBC (P = 0.00981). The overgrowth of Sphingomonadaceae and Pseudomonas in ileal MAM was found in patients with PBC. Sphingomonadaceae may be associated with the pathological development of PBC.

RESUMEN

Gastrointestinal motility is regulated by neural factors and humoral factors. Both motilin and ghrelin improve gastrointestinal motility, but many issues remain unclear. We prepared human motilin receptor transgenic (Tg) mice and performed experiments evaluating the effects of motilin, erythromycin (EM), and ghrelin. EM and ghrelin promoted gastric emptying (GE) when administered either peripherally or centrally to Tg mice. Atropine (a muscarinic receptor antagonist) counteracted GE induced by centrally administered EM, but not that induced by peripherally administered EM. The administration of EM in this model promoted the effect of mosapride (a selective serotonin 5-hydroxytryptamine 4 (5-HT4) receptor agonist), and improved loperamide (a µ-opioid receptor agonist)-induced gastroparesis. The level of acyl-ghrelin was significantly attenuated by EM administration. Thus, we have established an animal model appropriate for the evaluation of motilin receptor agonists. These data and the model are expected to facilitate the identification of novel compounds with clinical potential for relieving symptoms of dyspepsia and gastroparesis.

RESUMEN

Motilin is a gastrointestinal peptide hormone that stimulates gastrointestinal motility. Motilin is produced primarily in the duodenum and jejunum. Motilin receptors (MTLRs) are G protein-coupled receptors that may represent a clinically useful pharmacological target as they can be activated by erythromycin. The functions of motilin are highly species-dependent and remain poorly understood. As a functional motilin system is absent in rodents such as rats and mice, these species are not commonly used for basic studies. In this study, we examine the usefulness of human MTLR-overexpressing transgenic (hMTLR-Tg) mice by identifying the mechanisms of the gastric motor response to human motilin and erythromycin. The distribution of hMTLR was examined immunohistochemically in male wild-type (WT) and hMTLR-Tg mice. The contractile response of gastric strips was measured isometrically in an organ bath, while gastric emptying was determined using phenol red. hMTLR expression was abundant in the gastric smooth muscle layer. Interestingly, higher levels of hMTLR expression were observed in the myenteric plexus of hMTLR-Tg mice but not WT mice. hMTLR was not co-localized with vesicular acetylcholine transporter, a marker of cholinergic neurons in the myenteric plexus. Treatment with human motilin and erythromycin caused concentration-dependent contraction of gastric strips obtained from hMTLR-Tg mice but not from WT mice. The contractile response to human motilin and erythromycin in hMTLR-Tg mice was affected by neither atropine nor tetrodotoxin and was totally absent in Ca2+-free conditions. Furthermore, intraperitoneal injection of erythromycin significantly promoted gastric emptying in hMTLR-Tg mice but not in WT mice. Human motilin and erythromycin stimulate gastric smooth muscle contraction in hMTLR-Tg mice. This action is mediated by direct contraction of smooth muscle via the influx of extracellular Ca2+. Thus, hMTLR-Tg mice may be useful for the evaluation of MTLR agonists as gastric prokinetic agents.

RESUMEN

BACKGROUND: The efficacy of chemotherapy for unresectable pancreatic cancer has improved. However, it is occasionally difficult to make treatment decisions for elderly patients. We reviewed the outcomes of elderly patients with unresectable pancreatic cancer by using a large cohort and evaluated whether they had received chemotherapy and the reason why. METHODS: Data for 895 pancreatic cancer patients who were treated using chemotherapy or best supportive care were analyzed considering demographics, clinical stage, treatment, and outcome. Data were analyzed using the chi-square test, Student t-test, or Mann-Whitney U-test, as appropriate. Outcomes were analyzed using the Kaplan-Meier method. Differences in survival were analyzed using the log-rank test. RESULTS: The median survival time was significantly shorter in elderly patients (≥65 years) than in younger patients (<65 years) (181 vs. 263 days, P = 0.0001). The median survival time of patients treated with chemotherapy was not significantly different between the elderly and the younger group (274 days vs. 333 days, P = 0.09), and nor was that of patients choosing best supportive care (84 days vs. 78 days, P = 0.83). These results held true even when the age cut-off between younger and elder patients was increased to 70, 75, and 80 years. Elderly patients treated with chemotherapy had a significantly longer median survival time than those choosing best supportive care (274 vs. 86 days, P < 0.0001); a significantly greater proportion of elderly patients chose best supportive care compared to younger patients (47.8 vs. 25.8%, P < 0.0001). The reason for choosing best supportive care was established in 261 elderly patients (82.9%); 133 (51.0%) met the eligibility criteria for chemotherapy, but of these, 78 (58.6%) were not informed about their disease. The treatment preferences of elderly patients were not always considered; they often received only best supportive care per family members preference (N = 65, 48.8%) or because the physician based their treatment decision only on the patient's age (N = 68, 51.1%). CONCLUSIONS: Chemotherapy appears effective for elderly pancreatic cancer patients with unresectable disease, but treatment needs to be optimized to improve prognosis.

RESUMEN

A 63-year-old Japanese man whose white blood cell count and total-bilirubin and aminotransferase levels were elevated was referred to our hospital. Computed tomography did not reveal any abnormalities, and there was no evidence of gastritis or colitis on esophagogastroduodenoscopy. Although the patient had no history of drug use or allergies, a high concentration of eosinophils (80%) was noted. A liver biopsy revealed hepatitis with eosinophilic infiltration. The patient's alanine aminotransferase and eosinophil levels improved with the administration of steroids. A second biopsy, performed 6 months later, showed the improvement of the eosinophilic infiltration. The patient was diagnosed with eosinophilic hepatitis due to the presence of hypereosinophilic syndrome without the dysfunction of other organs.

RESUMEN

BACKGROUND: Effective surveillance for hepatocellular carcinoma (HCC) in diabetes mellitus (DM) has not been established. We elucidated the risk factors for HCC in DM patients. METHODS: From 2000 to 2014, 80 patients diagnosed with HCC for the first time who had concomittant DM but no other etiology of liver disease were enrolled as the DM-HCC group. From 2005 October to 2014, after introduction of the abdominal ultrasonography (US) report database, 2083 DM patients with no viral hepatitis, no known autoimmune hepatic diseases, and/or no evidence of alcohol abuse (>60 g/day) were enrolled as the DM-US group. Findings from the first US screening were evaluated. "Elderly" patients were defined as those aged >65 years. Clinical features of DM-HCC patients were evaluated and compared with those of DM-US patients. RESULTS: In the DM-HCC group (54 men, 26 women), the mean (± SD age was 74.1 ± 8.5 years, and mean HbA1c and fibrosis-4 (FIB-4) index were 7.3 ± 1.3% and 4.50 ± 3.42, respectively. Mean tumor diameter was 5.7 ± 3.5 cm, there were 63/13/2/2 patients classified as Child-Pugh A/B/C/unknown, and 56/24 were single/multiple lesions. In the DM-US group, HCC was detected in three patients (0.14%; 0.3% of those classified as elderly). The mean age and FIB-4 index of these three patients (one man, two women) were 75.6 years (range 67-92 years) and 4.84 (range 2.87-6.98), respectively. Mean tumor diamter was 7.6 cm and there were one and two single and multiple lesions, respectively. In elderly DM-US patients with a high FIB-4 index (≥4), the rate of HCC detection was 5.0%. CONCLUSIONS: Being elderly and having a high FIB-4 index are characteristic features of DM-HCC. Similar characteristics were noted for patients with HCC in the DM-US group. HCC surveillance with US is recommended for DM patients, especially those who are elderly (≥65 years) and have a high FIB-4 index.

RESUMEN

BACKGROUND AND AIM: The Child-Pugh classification has some non-objective factors, with chronic hepatitis indistinguishable from early liver cirrhosis in Child-Pugh A. We retrospectively evaluated the efficacy of albumin-bilirubin (ALBI) grade, which has been proposed as a new classification for hepatic function, for grading hepatocellular carcinoma (HCC) patients based on hepatic function and predicting their prognosis. METHOD: From 2000 to 2014, 2584 naïve HCC [69.0 ± 9.8 years old, 1850 men, 734 female, Child-Pugh class A:B:C = 1871:558:155] were enrolled. TNM staging was determined using the classification of the Liver Cancer Study Group of Japan and ALBI grade, instead of Child-Pugh classification (ALBI with TNM score: ALBI-T score) (Table 1), and is similar to the Japan Integrated Staging (JIS) score. We retrospectively compared ALBI-T and JIS scores in these patients. RESULTS: Of patients classified as Child-Pugh A (n = 1871), 1285 with 5 points were divided into 858 with ALBI grade 1 and 427 with grade 2, while 586 with 6 points were divided into 53 with grade 1 and 533 with grade 2. The ratio of ALBI grade 2 patients with a Child-Pugh score of 6 points (91.0%) was similar to that of those with 7 points (91.8%). Patients with a lower ALBI-T score (0-5 points) showed a better median survival time than those with a corresponding lower JIS score [137.7:83.2:53.4:27.4:5.0:1.4 vs 97.6:74.9:39.7:15.0:4.0:1.0 months]. CONCLUSION: Albumin-bilirubin grade was found to be superior for distinguishing patients with better hepatic function. ALBI-T scoring may be a better total prognostic scoring system for predicting survival of Japanese patients with HCC.

RESUMEN

BACKGROUND/AIM: We examined tumor marker levels to assess in more detail transcatheter arterial chemoembolization (TACE)-refractory hepatocellular carcinoma (HCC). MATERIALS AND METHODS: We enrolled patients treated from 2000 to 2011 for HCC beyond the Milan criteria who had good hepatic reserve function (Child-Pugh A) and no portal vein thrombosis or metastases (n = 154). The modified criteria for being TACE-refractory according to the Liver Cancer Study Group of Japan (m-LCSGJ), from which the tumor marker item was excluded, and the Assessment for Retreatment with TACE (ART) score were used for determining whether the HCC was TACE refractory. α-Fetoprotein ≥ 100 ng/ml, fucosylated α-fetoprotein ≥ 10%, and des-gamma-carboxy prothrombin ≥ 100 mAU/ml were used to define whether tumor markers were positive. We added up the number of positive tumor markers as a prognostic score to assess in more detail the evaluation of TACE-refractory HCC. RESULTS: In order to divide the patients into a refractory and nonrefractory group, the m-LCSGJ criteria [mean survival time (MST) 27.1 vs. 49.9 months; p < 0.001] were superior to the ART score (MST 22.0 vs. 35.1 months; p = 0.051). In the refractory group according to the m-LCSGJ criteria, the patients with a low score of positive tumor markers (<2) after 2 sessions of TACE (n = 36) showed a better prognosis than the others (n = 72) (MST 37.7 vs. 23.2 months; p = 0.014). CONCLUSION: Patients being nonrefractory according to the m-LCSGJ criteria had a better response, and using the number of tumor markers (≥ 2) is an easy method for predicting the response to TACE and for a more detailed evaluation of TACE-refractory HCC.
