Clinical role of radiofrequency ablation for early-stage hepatocellular carcinoma in an advanced aging society.

AIM: It is unclear whether prognosis differs by age for early-stage hepatocellular carcinoma (HCC). We aimed to examine prognosis and recurrence after radiofrequency ablation (RFA) for early-stage HCC and to determine its prognostic factors for different age groups. METHODS: This retrospective study enrolled 1079 patients with initial early-stage HCC treated with RFA at two institutions. All patients in this study were divided into four groups: <70 years old (group1, n = 483), 70-74 years old (group2, n = 198), 75-79 years old (group3, n = 201), and ≥80 years old (group4, n = 197). Prognostic factors were evaluated by comparing survival and recurrence rates between each group. RESULTS: The median survival time and 5-year survival rates for each group were 113 months and 70.8% in group1, 99.2 months and 71.5% in group2, 91.3 months and 66.5% in group3, and 71 months and 52.6% in group 4, respectively. Group4 had a significantly shorter survival than the other groups (p < 0.05). There were no significant differences in recurrence-free survival among the groups. In group4, the most common cause of death was nonliver-related disease (69.4%). In all groups, modified albumin-bilirubin index grade was a factor contributing to prolonged prognosis, but only in group4 performance status (PS) was a significant factor (hazard ratio, 2.46; 95% confidence interval, 1.16-3.00; p = 0.009). CONCLUSION: For early-stage HCC in the elderly, preoperative evaluation of PS and management of other diseases could contribute to a prolonged prognosis.

Patients with Chronic Liver Disease under Surveillance for Hepatocellular Carcinoma Have a Favorable Long-Term Outcome for Pancreatic Cancer Due to Early Diagnosis and High Resection Rate.

Patients with viral hepatitis-related chronic liver disease (CLD) under surveillance for hepatocellular carcinoma (HCC) are often diagnosed with pancreatic cancer (PC) at an early stage. However, the long-term outcomes of these patients are unclear. We aimed to clarify the long-term outcomes of patients with PC with viral hepatitis-related CLD using a chart review. Data collection included the Union for International Cancer Control (UICC) stage at PC diagnosis, hepatitis B virus and hepatitis C virus status, and long-term outcomes. The distribution of the entire cohort (N = 552) was as follows: early stage (UICC 0-IB; n = 52, 9.5%) and non-early stages (UICC IIA-IV; n = 500, 90.5%). At diagnosis, the HCC surveillance group (n = 18) had more patients in the early stages than the non-surveillance group (n = 534) (50% vs. 8.0%), leading to a higher indication rate for surgical resection (72.2% vs. 29.8%) and a longer median survival time (19.0 months vs. 9.9 months). We confirmed that patients with viral hepatitis-related CLD under HCC surveillance were diagnosed with PC at an early stage. Because of the higher indication rate for surgical resection in these patients, they had favorable long-term outcomes for PC.

Metastasis from Renal Cell Carcinoma to Ectopic Pancreas Diagnosed after Resection.

We herein report a 68-year-old man who underwent nephrectomy for right renal cell carcinoma 10 years prior. He remained under regular medical observation, and abdominal computed tomography showed tumors in the head and tail of the pancreas. He was diagnosed with pancreatic metastasis from renal cell carcinoma. He underwent surgical excision. The pathologic diagnosis proved that the pancreatic tumors were metastases from renal cell carcinoma and clarified that an ectopic pancreas in the duodenum had metastases as well. To our knowledge, this is the first case of metastasis to an ectopic pancreas.

Germline variants in cancer-predisposing genes in pancreatic cancer patients with a family history of cancer.

BACKGROUND: Our phase II trial (FABRIC study) failed to verify the efficacy of gemcitabine plus oxaliplatin (GEMOX) in patients with pancreatic ductal adenocarcinoma (PDAC) with a familial or personal history of pancreatic, breast, ovarian or prostate cancer, which suggested that a family and personal history may be insufficient to determine response to platinum-based chemotherapy. METHODS: This ancillary analysis aimed to investigate the prevalence of germline variants of homologous recombination repair (HRR)-related genes and clarify the association of germline variants with the efficacy of GEMOX and patient outcome in PDAC patients. Of 45 patients enrolled in FABRIC study, 27 patients were registered in this ancillary analysis. RESULTS: Of the identified variants in HRR-related genes, one variant was considered pathogenic and eight variants in six patients (22%) were variants of unknown significance (VUS). Objective response to GEMOX was achieved by 43% of the seven patients and tended to be higher than that of patients without such variants (25%). Pathogenic/VUS variant in HRR-related genes was an independent favorable factor for progression-free survival (hazard ratio, 0.322; P = 0.047) and overall survival (hazard ratio, 0.195; P = 0.023) in multivariable analysis. CONCLUSIONS: The prevalence of germline variants in PDAC patients was very low even among patients with a familial/personal history of pancreatic, breast, ovarian or prostate cancer. Patients with one or more germline variants in HRR-related genes classified as pathogenic or VUS may have the potential to obtain better response to GEMOX and have better outcomes.

A case of walled-off necrosis extending into the pelvic cavity successfully treated by endoscopic necrosectomy using a lumen-apposing metal stent.

A 31-year-old man developed massive walled-off necrosis extending into the pelvic cavity following severe acute alcoholic pancreatitis. Endoscopic ultrasound-guided fistula drainage was performed using a lumen-apposing metal stent, but this was insufficiently effective, and endoscopic necrosectomy was also performed, after which the patient improved. Percutaneous drainage and surgery are other options for the treatment of walled-off necrosis extending into the pelvic cavity, but a valuable case in which the patient improved with endoscopic treatment alone is presented.

Endoscopic duodenal stent placement versus gastrojejunostomy for unresectable pancreatic cancer patients with duodenal stenosis before introduction of initial chemotherapy (GASPACHO study): a multicenter retrospective study.

BACKGROUND: Endoscopic duodenal stent placement is an alternative technique to gastrojejunostomy for gastric outlet obstruction due to pancreatic cancer. We compared the efficacy of endoscopic duodenal stent placement with that of gastrojejunostomy for treating patients with pancreatic cancer who are candidates for intensive combination chemotherapies as the first line of treatment. METHODS: This retrospective observational study included 100 patients from 18 institutions in Japan. Inclusion criteria were as follows: (1) cytologically or histologically confirmed adenocarcinoma of the pancreas, (2) good performance status, (3) gastric outlet obstruction scoring system score of 0-1 and (4) no history of treatment for pancreatic cancer. RESULTS: There was no significant difference in the background characteristics of patients in the endoscopic duodenal stent placement (n = 57) and gastrojejunostomy (n = 43) groups. The median overall survival in the endoscopic duodenal stent placement and gastrojejunostomy groups was 5.9 and 6.0 months, respectively. Clinical success was achieved in 93 cases; the median time to food intake resumption was significantly shorter in the endoscopic duodenal stent placement group (median: 3 days, n = 54) than in the gastrojejunostomy group (median: 5 days, n = 43). Chemotherapy was introduced in 63% of the patients in both groups after endoscopic duodenal stent placement or gastrojejunostomy. Chemotherapy was started earlier in the endoscopic duodenal stent placement group (median: 14 days) than in the gastrojejunostomy (median: 32 days) group. CONCLUSIONS: Endoscopic duodenal stent placement showed similar or better clinical outcomes than gastrojejunostomy. Thus, it might be a promising option in patients with good performance status.

Simple prognostic markers for optimal treatment of patients with unresectable pancreatic cancer.

ABSTRACT: Most patients with pancreatic cancer are ineligible for curative resection at diagnosis, resulting in poor prognosis. This study aimed to evaluate the prognostic factors in patients with unresectable pancreatic cancer.We retrospectively collected clinical data from 196 patients with unresectable pancreatic cancer who received palliative chemotherapy (N = 153) or palliative care alone (N = 43) from January 2011 to December 2013. Patients' background data and overall survival were analyzed using the Cox proportional hazard regression model.In patients receiving palliative chemotherapy (gemcitabine-based regimen, 88.2%) and palliative care alone, the median (range) ages were 68 (43-91) and 78 (53-90) years, and metastatic diseases were present in 80% (N = 123) and 86% (N = 37), respectively. Multivariate analysis in the palliative chemotherapy patients showed that liver metastasis (hazard ratio [HR] 2.25, 95% confidence interval [CI] 1.58-3.20, P < .001), neutrophil-to-lymphocyte ratio (>4.5 vs ≤4.5; HR 3.45, 95% CI 2.22-5.36, P < .001), and cancer antigen 19-9 (CA19-9) (≥900 vs <900 U/mL; HR 1.45, 95% CI 1.02-2.05, P = .036) were independent prognostic factors. In those receiving palliative care alone, lung (HR 3.27, 95% Cl 1.46-7.35, p = 0.004) and peritoneum (HR 2.50, 95% CI 1.20-5.18, P = .014) metastases and the C-reactive protein-to-albumin ratio (≥1.3 vs <1.3; HR 3.33, 95% Cl 1.51-7.35, P = .003) were independent prognostic factors. Furthermore, patients with multiple factors had worse prognosis in both groups. Median survival time of palliative chemotherapy patients with risk factors 0, 1, 2, and 3 were 13.1 (95% CI 8.0-16.9), 9.4 (95% CI 7.9-10.1), 6.6 (95% CI 4.9-7.8), and 2.5 (95% CI 1.7-4.0) months, respectively. Similarly, median survival time was 5.7 (95% CI 1.3 -8.0), 2.1 (95% CI 1.5-3.9), and 1.3 (95% CI 0.6-1.7) months, respectively, for palliative care alone patients with risk factor 0, 1, and 2 to 3.Prognostic markers for pancreatic cancer were neutrophil-to-lymphocyte ratio, liver metastasis, and CA19-9 in patients undergoing palliative chemotherapy and C-reactive protein-to-albumin ratio and lung/peritoneum metastases in patients undergoing palliative care alone. These simple markers should be considered when explaining the prognosis and therapeutic options to patients.

Direct-acting antivirals improve survival and recurrence rates after treatment of hepatocellular carcinoma within the Milan criteria.

BACKGROUND: The effects of direct-acting antivirals (DAAs) on survival and recurrence rates after curative hepatocellular carcinoma (HCC) treatment in patients with hepatitis C virus (HCV) infection remain controversial. METHODS: This retrospective, multicenter study involved Child-Pugh class A patients within the Milan criteria who had a first diagnosis of HCC and survived 6 months or longer after undergoing hepatectomy or radiofrequency ablation (RFA). The DAA-treated group (DAA group) included 56 patients, and the DAA-untreated group (untreated group) included 261 patients. The study was conducted using the propensity score-matched (1:2) DAA group and untreated group, 56 and 112 patients, respectively. RESULTS: The survival rate at 48 months in the DAA group and the untreated group was 91.0% and 68.7%, respectively, showing significantly better survival in the DAA group (HR: 0.33; 95% CI 0.13-0.84; p = 0.021). The recurrence rate at 48 months was 36.7% and 66.7%, respectively, showing a significantly lower recurrence rate in the DAA group (HR, 0.46; 95% CI 0.27-0.77; p = 0.003). The median albumin-bilirubin (ALBI) score at 3 years post-HCC treatment was - 2.84 in the DAA group and - 2.34 in the untreated group. The ALBI score showed a significant improvement from baseline to 3 years post-HCC treatment (p = 0.001), whereas that in the untreated group showed a significant decline (p = 0.040). CONCLUSIONS: DAAs after HCC treatment prevents deterioration of hepatic functional reserve and significantly improves both recurrence and survival rates.

Endoscopic placement of covered versus uncovered self-expandable metal stents for palliation of malignant gastric outlet obstruction.

OBJECTIVE: Stenting is an established endoscopic therapy for malignant gastric outlet obstruction (mGOO). The choice of stent (covered vs uncovered) has been examined in prior randomised studies without clear results. DESIGN: In a multicentre randomised prospective study, we compared covered (CSEMS) with uncovered self-expandable metal stents (UCSEMS) in patients with mGOO; main outcomes were stent dysfunction and patient survival, with subgroup analyses of patients with extrinsic and intrinsic tumours. RESULTS: Overall survival was poor with no difference between groups (probability at 3 months 49.7% for covered vs 48.4% for uncovered stents; log-rank for overall survival p=0.26). Within that setting of short survival, the proportion of stent dysfunction was significantly higher for uncovered stents (35.2% vs 23.4%, p=0.01) with significantly shorter time to stent dysfunction. This was mainly relevant for patients with extrinsic tumours (stent dysfunction rates for uncovered stents 35.6% vs 17.5%, p<0.01). Subgrouping was also relevant with respect to tumour ingrowth (lower with covered stents for intrinsic tumours; 1.6% vs 27.7%, p<0.01) and stent migration (higher with covered stents for extrinsic tumours: 15.3% vs 2.5%, p<0.01). CONCLUSIONS: Due to poor patient survival, minor differences between covered and uncovered stents may be less relevant even if statistically significant; however, subgroup analysis would suggest to use covered stents for intrinsic and uncovered stents for extrinsic malignancies.

ABO Blood Type and the Long-term Outcomes of Pancreatic Cancer.

Objective The long-term effect of the ABO blood type on the clinical course of patients with pancreatic cancer (PC) is inconclusive. This study aimed to determine whether or not the ABO blood type influences the long-term outcomes of PC in Japanese patients. Methods The medical records of Japanese patients with PC were reviewed. Data, including the age, sex, and outcomes, from the Ehime Pancreato-Cholangiology Study Group were analyzed. Results The mean age of the 406 patients was 71.0±10.5 years, and 220 (54.2%) were men. A total of 44.6%, 20.7%, 22.4%, and 12.3% had blood type A, B, O, and AB, respectively. The median survival time (MST) of patients with A alleles was shorter than that of patients with non-A alleles (p=0.048), especially among those who underwent resection (p=0.031). In contrast, no marked difference in the MST was noted among those who underwent chemotherapy and palliative care. Finally, a multivariate analysis confirmed A alleles as an independent factor associated with the long-term outcome of PC (p<0.05 in 2 different models). Conclusion The ABO blood type influenced the long-term outcomes of Japanese patients with PC, presumably due to its impact on disease onset and tumor behavior.

Early Detection of Pancreatic Cancer in Patients With Chronic Liver Disease Under Hepatocellular Carcinoma Surveillance.

OBJECTIVE: To evaluate whether patients with hepatitis B virus (HBV)- and hepatitis C virus (HCV)-related chronic liver disease were diagnosed as having pancreatic cancer (PC) at an early stage during abdominal imaging surveillance for hepatocellular carcinoma (HCC). PATIENTS AND METHODS: We retrospectively examined 447 patients with PC diagnosed at Ehime University Hospital and affiliated centers (2011-2013). Data were collected regarding HBV and HCV status, likelihood of PC diagnosis, and Union for International Cancer Control (UICC) stage. Intergroup comparisons were performed using the χ2 test. RESULTS: The UICC stage distribution in the HCC surveillance group (n=16) was stage 0 (n=2, 12.5%), stage IA (n=3, 18.8%), stage IB (n=2, 12.5%), stage IIA (n=2, 12.5%), stage IIB (n=2, 12.5%), stage III (n=1, 6.3%), and stage IV (n=4, 25%). The UICC stage distribution in the nonsurveillance group (n=431) was stage 0 (n=4, 0.9%), stage IA (n=28, 6.5%), stage IB (n=27, 6.3%), stage IIA (n=86, 20.0%), stage IIB (n=48, 11.1%), stage III (n=56, 13.0%), and stage IV (n=182, 42.2%). The HCC surveillance group had significantly more patients with stage 0 disease than with stages IA through IV (P=.02). Similar results were observed when including stages IA (P=.007) and IB (P=.004) as early stages but not stage IIA (P=.10). A dilated pancreatic duct led to a PC diagnosis in all 6 patients with stage 0 disease. CONCLUSION: Patients with HBV- and HCV-related chronic liver disease had an early PC diagnosis during HCC surveillance. Careful evaluation of the pancreas is warranted during HCC surveillance.

Relation of Reduction of Antibodies against Hepatitis B Virus to Hepatocellular Carcinoma Recurrence in the Patients with Resolved Hepatitis B Virus Infection Following Direct-acting Antiviral Therapy for Hepatitis C Virus Infection.

BACKGROUND: A possible interaction of hepatitis viruses at cellular and molecular levels has been suggested. Eradication of hepatitis C virus (HCV) has been reported to induce activation of hepatitis B virus (HBV)-related liver diseases. MATERIALS AND METHODS: The present study examined association of HBV markers with recurrence of hepatocellular carcinoma (HCC) in patients with resolved HCV infection by direct-acting antiviral (DAA) therapy. In a patient pool of 378 patients with sustained virologic response (SVR) by DAA, the antibody to the hepatitis B surface antigen (anti-HBs), the antibody to the hepatitis B core antigen (anti-HBc), and HBV-DNA levels were estimated before and at the end of DAA therapy. These patients were HBsAg negative. Eighty-nine patients had a history of curative treatment of HCC by resection or radiofrequency ablation. A Cox proportional hazards model was used to identify risk factors for HCC recurrence, including the change ratio of the antibody against HBV proteins. RESULTS: Although 188 patients had resolved HBV infection, no patient showed HBV reactivation, but anti-HBs and anti-HBc levels decreased significantly. No significant difference in the HCC recurrence rate was evident between patients with and without resolved HBV infection. Changes of immune responses to HBV proteins did not affect HCC recurrence after DAA therapy for HCV infection in this cohort. CONCLUSION: The mechanisms underlying diverse roles of DAA-induced SVR of HCV on HBV kinetics need to be resolved in future. HOW TO CITE THIS ARTICLE: Joko K, Mashiba T, Ochi H, et al.

Multi-center clinical evaluation of streptozocin-based chemotherapy for advanced pancreatic neuroendocrine tumors in Japan: focus on weekly regimens and monotherapy.

PURPOSE: Streptozocin (STZ) is a key agent for treating advanced pancreatic neuroendocrine tumors (pNET). Most STZ regimens for pNET are daily and also include 5-fluorouracil (5FU), whereas STZ monotherapy and weekly regimens have also been applied in daily practice in Japan. The present study aimed to evaluate responses to weekly regimens and to STZ monotherapy, and to identify a predictive marker of a response to STZ. METHODS: Clinical data regarding STZ-based chemotherapy for pNET were collected between 2015 and 2017 at 25 facilities. We analyzed the effects, safety, progression-free survival (PFS), and factors that correlate with responses to STZ. RESULTS: The overall objective response rate (ORR) of 110 patients who underwent STZ-based chemotherapy (monotherapy, 81.8%; weekly regimen 46.4%) was 21.8%, and PFS was 9.8 months. The ORR of weekly vs. daily regimens was 21.6 vs. 22.0% (P = 1.000), and that of monotherapy vs. combination therapy was 21.1 vs. 25.0% (P = 0.766). A Ki67 proliferation index (Ki67) of > 5% was a predictive marker of a response to STZ (P = 0.017), whereas regimen type, mono- or combination therapy, treatment line and liver tumor burden were not associated with responses. The frequencies of Grade ≥ 3 nausea and hematological adverse events were significantly lower for monotherapy than combination therapy (P = 0.032). CONCLUSIONS: The effects of weekly STZ monotherapy on pNET are comparable to those previously reported and the toxicity profile was acceptable. Ki67 > 5% was the sole predictive marker of an objective response.

Diagnostic Challenge in Pancreatic Sarcoidosis Using Endoscopic Ultrasonography.

We herein report a 55-year-old woman who presented with erythema and bilateral hilar lymphadenopathy 4 months prior to the detection of pancreatic lesions on an ultrasound. A skin biopsy showed evidence of sarcoidosis. The largest lesion in the tail of the pancreas was hypoechoic on endoscopic ultrasonography (EUS). The lesion was initially iso-enhanced on contrast enhanced-EUS (CE-EUS) but subsequently became hypoenhanced. The lesion revealed heterogeneous components of both soft and hard tissue on EUS elastography. She was ultimately diagnosed with pancreatic sarcoidosis based on the presence of noncaseating granulomas seen on pancreatic tissue retrieved through an EUS-guided fine needle aspiration biopsy.

Efficacy of chemotherapy in elderly patients with unresectable pancreatic cancer: a multicenter review of 895 patients.

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.

A Possible Case of Hepatitis due to Hypereosinophilic Syndrome.

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.

Difficulty in management of intraductal papillary mucinous neoplasm-associated pancreatobiliary fistulas and the role of "pig-nose" appearance and intraductal ultrasonography in diagnosis.

Pancreatobiliary fistulas associated with intraductal papillary mucinous neoplasms (IPMN) often develop obstructive jaundice and cholangitis; thus, early diagnosis is important. However, computed tomography and cholangiography, the current methods for detecting pancreatobiliary fistulas, are not always effective. We previously reported a case of IPMN-associated pancreatobiliary fistula and proposed a potential new diagnostic marker: the "pig-nose" appearance of the duodenal papilla, which results from dilated pancreatic and bile ducts and can be visualized via endoscopy. In this study, we report another three cases of IPMN-associated pancreatobiliary fistulas detected by a different technology, intraductal ultrasonography (IDUS). As with our previously reported case, we confirmed the utility of the "pig-nose" appearance and IDUS in the diagnosis of IPMN-associated pancreatobiliary fistulas. In addition, we found it difficult to manage biliary obstruction that resulted from the flow of mucinous material through pancreatobiliary fistulas. The obstruction was treated with endoscopic nasal biliary drainage (ENBD), but this was not always successful. In two of our cases, additional treatment with a large diameter fully covered metal stent failed to improve jaundice. Therefore, we conclude that standard endoscopic stenting may not be effective, and that alternative endoscopic methods or surgery may be necessary.

Ultrasonography screening for hepatocellular carcinoma in Japanese patients with diabetes mellitus.

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.

Usefulness of albumin-bilirubin grade for evaluation of prognosis of 2584 Japanese patients with hepatocellular carcinoma.

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.

Tumor Markers AFP, AFP-L3, and DCP in Hepatocellular Carcinoma Refractory to Transcatheter Arterial Chemoembolization.

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.
