[A Case of Undifferentiated Sarcoma of the Liver in an Adult Treated with Right Hepatectomy Followed by Adjuvant Chemotherapy].

Undifferentiated sarcoma of the liver is rare, especially in adults, and is an aggressive malignancy that originates from the primary mesenchymal tissues. A 53-year-old man was referred to our hospital for further evaluation of a low-grade fever. Contrast-enhanced CT revealed an 18-cm tumor in the right lobe of the liver. The tumor was characterized by low-density areas suspected of cystic components, a high-density area suspected of hemorrhage, and contrast enhancement in the thickened marginal and internal septa. MRI revealed a high-intensity tumor with a heterogeneous structure on T2-weighted images. Angiosarcoma of the liver with intratumoral hemorrhage was suspected, and right hepatectomy was performed. The pathological diagnosis was an undifferentiated sarcoma based on the presence of undifferentiated mesenchymal tumor cells with a stellate to spindle-shaped pleomorphism. Following a multidisciplinary discussion, 4 courses of the AI regimen (doxorubicin and ifosfamide)were administered as adjuvant chemotherapy, and no recurrence was confirmed at 2 years and 6 months follow-up. Our case suggests that radical resection followed by adjuvant chemotherapy may contribute to a favorable prognosis for undifferentiated sarcoma of the liver.

The Impact of Nutritional Support on Survival Outcomes in Patients with Advanced Gastric Adenocarcinoma Treated with Chemotherapy.

Malnutrition and cachexia occur commonly in patients with advanced gastric cancer (AGC). This study elucidated the effect of nutritional support (NS) on survival outcomes among patients with AGC undergoing chemotherapy. We retrospectively evaluated new AGC cases at our institute between January 2015 and January 2021. Inclusion criteria were unresectable or recurrent chemotherapy-treated gastric adenocarcinoma, ECOG performance status (PS) 0-2, and adequate organ function. Time to treatment failure (TTF) and overall survival (OS) were evaluated, and univariate and multivariate analyses identified prognostic factors. A total of 103 eligible patients were separated into groups: 69 patients (67%) into NS and 34 (33%) into routine care (RC). The median follow-up time was 11.0 mo, (0.5-92). NS was offered to patients with poorer PS (p = 0.03), Glasgow prognostic score (GPS) positivity (p = 0.001), and high neutrophil-to-lymphocyte ratios (cut-off ≤ 3, p = 0.02). Median OS and TTF in the RC and NS groups were 11.6 and 10.4 mo, (p = 0.99) and 4.2 and 5.5 mo, (p = 0.07), respectively. Multivariate analyses identified NS (hazard ratio [HR] = 0.53, p = 0.01) and GPS positivity for TTF, and low body mass index (HR = 2.03, p = 0.007) and GPS positivity (HR = 2.25, p = 0.001) for OS as significant prognostic factors. Thus, NS with chemotherapy is a potentially effective intervention for AGC.

Evaluating patient acceptability and bowel preparation efficacy of sodium picosulfate-magnesium citrate for colonoscopy.

Objective: To evaluate patient acceptability and bowel preparation efficacy of sodium picosulfate-magnesium citrate (PICOPREP) for colonoscopy. Methods: A questionnaire survey regarding the patient acceptability of bowel preparation agent PICOPREP was administered to 54 patients, and its efficacy was evaluated using the Ottawa Bowel Preparation Scale (OBPS). Results: Eighteen (33.3%) participants reported that PICOPREP is very easy to drink, 30 (55.5%) easy, four (7.4%) acceptable, one (1.9%) difficult, and one (1.9%) very difficult. The flavor was very good as reported by eight (14.8%) participants, good by 25 (46.3%), neutral by 20 (37.0%), bad by one (1.9%), and very bad by none. The number of patients who requested PICOPREP was 42 (77.7%), indicating its high acceptability. Evaluation of the OBPS score showed that the rectosigmoid colon had significantly better polyethylene glycol (PEG) scores than PICOPREP, but the entire colon did not show a significant difference between PICOPREP and PEG scores (1.09 ± 0.65 vs. 1.17 ± 0.76, p = 0.632 in the right colon; 0.48 ± 0.52 vs. 0.72 ± 0.66, p = 0.079 in the mid colon, 0.93 ± 0.49 vs. 0.63 ± 0.52, p = 0.012 in the rectosigmoid colon, and 3.28 ± 1.70 vs. 3.20 ± 1.90, p = 0.836 in the entire colon). Conclusion: PICOPREP is considered as one of the important options due to its good patient acceptability and high efficacy similar to PEG.

Evaluation of Muscle Cramp Associated with Liver Cirrhosis with a Focus on the Liver Function and Nutritional Status.

Objective We investigated the muscle cramp status of patients with liver cirrhosis by focusing on the degree of liver damage, skeletal muscle mass, and nutritional status. Methods All enrolled patients completed a questionnaire about muscle cramps. The degree of liver damage was examined using the Child-Pugh classification and the albumin-bilirubin (ALBI) grade. The nutritional status and skeletal muscle mass were examined using the Controlling Nutritional Status (CONUT) method and the psoas muscle index (PMI). Results Among the respondents, 55.7% of the patients reported experiencing muscle cramps. An analysis of the two patient groups-those who experienced muscle cramps and those who did not-revealed significant differences in Child-Pugh classification (muscle cramp-positive vs. muscle cramp-negative: A/B/C, 54.1%/32.4%/13.5% vs. 90.0%/10.0%/0.0%; p=0.004), ALBI grade (1/2/3, 20.5%/71.8%/7.7% vs. 54.8%/38.7%/6.5%; p=0.011), modified ALBI grade (1/2a/2b/3, 20.5%/20.5%/51.3%/7.7% vs. 54.8%/22.6%/16.1%/6.5%; p=0.008), CONUT score (normal/mild/moderate/severe, 25.6%/28.2%/41.0%/5.1% vs. 22.6%/61.3%/12.9%/3.2%; p=0.024), and PMI (3.85±1.13 cm2/m2 vs. 4.94±1.86 cm2/m2; p=0.012). Conclusion Our findings suggest that muscle cramps occur more frequently in patients with liver cirrhosis due to their decreased liver function and poorer nutritional status.

Association of soluble T cell immunoglobulin domain and mucin-3 (sTIM-3) and mac-2 binding protein glycosylation isomer (M2BPGi) in patients with autoimmune hepatitis.

BACKGROUND: Autoimmune hepatitis (AIH) is a disorder of unknown etiology in which immune-mediated liver injury progress to cirrhosis or hepatocellular carcinoma (HCC). The aim of the present study was to determine whether circulating soluble TIM3 (sTIM3) is elevated in patients with AIH patients and whether sTIM-3 levels are associated with clinical parameters of AIH. METHODS: We enrolled 123 Japanese patients with AIH who were identified from the National Hospital Organization-AIH-liver-network database, as well as 32 patients with chronic hepatitis C (CHC), 30 patients with primary biliary cholangitis (PBC) and healthy control subjects. Serum sTIM-3 concentrations were quantified by ELISA. RESULTS: Serum levels of sTIM-3 were significantly higher in AIH patients (median 4865 pg/ml; [interquartile range (IQR); 3122-7471]) compared to those in CHC (1026 pg/ml [IQR: 806-1283] p<0.001), PBC (2395 pg/ml [IQR: 2012-3422] p<0.001) or healthy controls (1285 pg/ml [IQR: 1098-1812] p<0.001). In AIH group, serum sTIM-3 were correlated with alanine aminotransferase (ALT), or total bilirubin (TB) and negatively correlated with serum levels of albumin (Alb). Serum levels of sTIM-3 were also strongly correlated with Mac-2 binding protein glycosylation isomer (M2BPGi) levels, but did not correlate with the histological grade of liver fibrosis. Steroid treatment of AIH patients significantly reduced serum sTIM-3 levels (2147±623pg/ml versus 1321±378pg/ml, p<0.001). CONCLUSIONS: Circulating sTIM-3 levels were elevated in AIH patients and are associated with AIH disease activity and AIH-related liver damage. These findings indicate that serum sTIM-3 correlated with disease status of AIH and could be useful biomarkers to detect autoimmune-mediated liver injury. Our data suggest a possible link between the TIM-3/GAL-9 pathway and AIH severity or phenotype, and further investigations of the TIM-3 pathway and AIH pathophysiology is warranted.

Galectin-9 in autoimmune hepatitis: Correlation between serum levels of galectin-9 and M2BPGi in patients with autoimmune hepatitis.

Autoimmune hepatitis (AIH) is a disorder of unknown etiology in which immune-mediated liver damage progresses to cirrhosis or hepatocellular carcinoma (HCC). The mainstay therapy for AIH is steroids and other immunosuppressive treatments. Currently, there are no validated markers for monitoring immune-mediated hepatic inflammation. Galectin-9 has recently been identified as a potential biomarker in patients with chronic liver disease. The objective of this study was to determine whether Galectin-9 and other serum proteins are associated with active disease in AIH patients.We enrolled 77 Japanese patients with well-documented AIH who were identified from the National Hospital Organization-AIH-liver-network database, as well as 32 patients with chronic hepatitis C (CHC), 27 patients with SLE, and 17 healthy control subjects. Serum levels of galectin-9, and markers of liver injury were measured and compared between groups.Serum levels of galectin-9 were significantly higher in AIH patients than in CHC patients (13.8 ±â€Š4.9 ng/mL vs 8.9 ±â€Š3.0 ng/mL, P < .001) or healthy controls (13.8 ±â€Š4.9 ng/mL vs 5.0 ±â€Š1.3 ng/mL, P < .001). In AIH group, serum galectin-9 levels weakly correlated with alanine aminotransferase levels or total bilirubin (TB) and strongly correlated with C-X-C motif chemokine 10 (CXCL10) and Mac-2 binding protein glycosylation isomer (M2BPGi) levels, but did not correlate with the histological grade of liver fibrosis. Steroid treatment of AIH patients significantly reduced serum galectin-9 levels (14.1 ±â€Š4.9 ng/mL vs 8.3 ±â€Š3.8 ng/mL, P < .001). SLE patients exhibited higher galectin-9 levels, whereas the galectin-9 levels did not correlate with liver function tests such as alanine aminotransferase levels.Serum galectin-9 correlated with disease status in AIH patients and could thus be useful biomarkers to detect hepatic autoimmunity. Because circulating galectin-9 reflects autoimmune-mediated inflammation, it may have additional utility as a biomarker for other autoimmune disorders.

Role of deleterious single nucleotide variants in the coding regions of TNFAIP3 for Japanese autoimmune hepatitis with cirrhosis.

Autoimmune hepatitis (AIH) is an autoimmune liver disease and cirrhosis is sometimes complicated with AIH at diagnosis, influencing its prognosis. TNFAIP3 gene encodes A20, an inhibitor of nuclear factor-κB pathway, and is a susceptibility gene for autoimmune diseases. We investigated deleterious variants in the coding regions of TNFAIP3 gene of Japanese AIH patients or those with cirrhosis. The deleterious variants in the coding regions of TNFAIP3 gene were analyzed by the cycle sequencing method and the frequencies of deleterious TNFAIP3 alleles of AIH or AIH with cirrhosis were compared with those of Japanese controls. The deleterious alleles in TNFAIP3 were not associated with AIH. A significant association was shown for the deleterious alleles in TNFAIP3 (P = 0.0180, odds ratio (OR) 4.28, 95% confidence interval (CI) 1.53-11.95) with AIH with cirrhosis at presentation. The serum IgM levels in AIH patients with deleterious alleles in TNFAIP3 were tended to be lower than those without (P = 0.0152, Q = 0.1216). The frequency of deleterious alleles in TNFAIP3 was higher in the AIH subset without the DRB1 risk alleles than that with (P = 0.0052, OR 5.10, 95%CI 1.55-16.74). The deleterious alleles in TNFAIP3were associated with AIH with cirrhosis.

Serum cytokine profiles and Mac-2 binding protein glycosylation isomer (M2BPGi) level in patients with autoimmune hepatitis.

Autoimmune hepatitis (AIH) is an autoimmune liver disease that is characterized by a progressive destruction of the liver parenchyma and the development of liver fibrosis. We aimed to examine the relationship between circulating cytokines/chemokines and the Mac-2 binding protein glycosylation isomer (M2BPGi) levels in Japanese patients with autoimmune hepatitis (AIH).We investigated the relationship between circulating cytokines/chemokines and M2BPGi levels in Japanese patients with AIH. Seventy-seven patients with well-documented AIH were enrolled in the National Hospital Organization (NHO)-AIH-liver-network database. We measured the serum levels of 20 cytokines in 31 selected AIH patients before and after steroid treatment using multisuspension cytokine array.Eleven cytokines and soluble adhesion molecules were increased in untreated AIH patients compared with treated AIH patients. Among these cytokines and soluble adhesion molecules, soluble intercellular adhesion molecule-1 (sICAM-1) and interferon-γ-inducible protein 10 (IP-10) were most downregulated by steroid therapy in AIH patients. We measured serum sICAM-1 and IP-10 by ELISA and found the levels were significantly higher in AIH patients (n = 77) compared with chronic viral hepatitis C patients (n = 32). Furthermore, there was a positive correlation between sICAM-1 or IP-10 and alanine aminotransferase, total bilirubin, and circulating M2BPGi levels. M2BPGi levels were increased in AIH patients with high stages of liver fibrosis. Additionally, M2BPGi levels were correlated with the histological grade of inflammation in AIH. Circulating M2BPGi levels were significantly reduced by steroid treatment in AIH patients.sICAM-1 and IP-10 are useful markers to assess immune-mediated hepatitis activity in AIH and they correlate with circulating M2BPGi. Serum M2BPGi levels increased in untreated AIH patients with active hepatitis and were decreased by steroid therapy. M2BPGi reflects autoimmune-mediated hepatic inflammation as well as liver fibrosis.

Circulating microRNA Profiles in Patients with Type-1 Autoimmune Hepatitis.

Recent studies have demonstrated that micro (mi)RNA molecules can be detected in the circulation and can serve as potential biomarkers of various diseases. This study used microarray analysis to identify aberrantly expressed circulating miRNAs in patients with type 1 autoimmune hepatitis (AIH) compared with healthy controls. Patients with well-documented and untreated AIH were selected from the National Hospital Organization (NHO)-AIH-liver-network database. They underwent blood sampling and liver biopsy with inflammation grading and fibrosis staging before receiving treatment. To further confirm the microarray data, circulating expression levels of miR-21 and miR-122 were quantified by real-time quantitative polymerase chain reaction in 46 AIH patients, 40 patients with chronic hepatitis C (CHC), and 13 healthy controls. Consistent with the microarray data, serum levels of miR-21 were significantly elevated in AIH patients compared with CHC patients and healthy controls. miR-21 and miR-122 serum levels correlated with alanine aminotransferase levels. Circulating levels of miR-21 and miR-122 were significantly reduced in AIH patients with liver cirrhosis, and were inversely correlated with increased stages of fibrosis. By contrast, levels of circulating miR-21 showed a significant correlation with the histological grades of inflammation in AIH. We postulate that aberrantly expressed serum miRNAs are potential biomarkers of AIH and could be implicated in AIH pathogenesis. Alternations of miR-21 and miR-122 serum levels could reflect their putative roles in the mediation of inflammatory processes in AIH.

Concurrent chemoradiotherapy with a novel fluoropyrimidine, S-1, and cisplatin for locally advanced esophageal cancer: long-term results of a phase II trial.

OBJECTIVES: A phase II study was performed to investigate the safety and efficacy of concurrent chemoradiotherapy (CCRT) combined with an orally active fluoropyrimidine, S-1, plus cisplatin for locally advanced esophageal cancer (LAEC). METHODS: CCRT comprised 2 courses, a 30-Gy radiotherapy over 3 weeks plus daily oral S-1 (80 mg/m(2)/day) for 2 weeks and a 24-hour cisplatin infusion (70 mg/m(2)) on day 8, and an identical course administered after a 2-week break. RESULTS: One hundred and sixteen patients, 12 with stage II, 71 with stage III, and 33 with stage IVa LAEC participated, and 106 of them (91.4%) completed the CCRT course. The most serious toxicity was myelosuppression: grade 3 and 4 neutropenia occurred in 28.4 and 9.5% of patients, respectively. Nonhematologic toxicity was moderate. Complete response rates in patients with stage II, III, and IVa LAEC were 91.7, 67.6, and 36.4%, respectively. The overall median survival time was 2.3 years and that of patients with stage II, III, and IVa cancer was 7.0, 2.6, and 1.3 years, respectively. CONCLUSIONS: CCRT combined with S-1 plus cisplatin showed promising safety and efficacy. Potentially, this combination therapy could become a baseline medication for patients with LAEC.

Hepatocellular carcinoma and survival in patients with autoimmune hepatitis (Japanese National Hospital Organization-autoimmune hepatitis prospective study).

BACKGROUND/AIMS: Although the outcome of autoimmune hepatitis (AIH) is generally good, the natural course and likelihood of progression to cirrhosis or hepatocellular carcinoma (HCC) remain undefined, and may vary by region and population structure. Our aims were to evaluate risk factors that contribute to poor outcome and particularly development of HCC in a prospective multicentric cohort study of AIH. METHODS: The study group comprised 193 Japanese patients with AIH who were prospectively followed up at annual intervals between 1995 and 2008. The mean follow-up period was 8.0 ± 4.5 years. RESULTS: Twenty-one (10.9%) patients had cirrhosis at presentation and a further 15 (7.8%) developed cirrhosis during the follow-up period. Survival rates were 94.2% at 10 years and 89.3% at 15 years. HCC was diagnosed in seven of the 193 patients. The presence of cirrhosis at presentation was a risk factor for HCC according to a Cox proportional hazard model, and the HCC-free survival rate was significantly lower in those with cirrhosis compared to those without cirrhosis according to Kaplan-Meier analysis. CONCLUSIONS: Although the outcome of AIH is as good if not better among Japanese than for other populations, there was an increased risk of HCC in these patients. Cirrhosis at presentation was predictive of development of HCC in AIH in Japan.

Sustained reduction in prevalence of lymphatic filariasis infection in spite of missed rounds of mass drug administration in an area under mosquito nets for malaria control.

BACKGROUND: The Global Programme to Eliminate Lymphatic Filariasis (GPELF) was established by the World Health Organisation (WHO) in 2000 with the goal of eliminating lymphatic filariasis (LF) as a public health problem globally by 2020. Mass drug administration (MDA) of antifilarial drugs is the principal strategy recommended for global elimination. Kenya launched a National Programme for Elimination of Lymphatic Filariasis (NPELF) in Coast Region in 2002. During the same year a longitudinal research project to monitor trends of LF infection during MDA started in a highly endemic area in Malindi District. High coverage of insecticide treated nets (ITNs) in the coastal region has been associated with dramatic decline in hospital admissions due to malaria; high usage of ITNs is also expected to have an impact on LF infection, also transmitted by mosquitoes. RESULTS: Four rounds of MDA with diethylcarbamazine citrate (DEC) and albendazole were given to 8 study villages over an 8-year period. Although annual MDA was not administered for several years the overall prevalence of microfilariae declined significantly from 20.9% in 2002 to 0.9% in 2009. Similarly, the prevalence of filarial antigenaemia declined from 34.6% in 2002 to 10.8% in 2009. All the examined children born since the start of the programme were negative for filarial antigen in 2009. CONCLUSIONS: Despite the fact that the study villages missed MDA in some of the years, significant reductions in infection prevalence and intensity were observed at each survey. More importantly, there were no rebounds in infection prevalence between treatment rounds. However, because of confounding variables such as insecticide-treated bed nets (ITNs), it is difficult to attribute the reduction to MDA alone as ITNs can lead to a significant reduction in exposure to filariasis vectors. The results indicate that national LF elimination programmes should be encouraged to continue provision of MDA albeit constraints that may lead to missing of MDA in some years.

A pilot study of leukocytapheresis efficacy with 1.5 liter blood processing volume in patients with ulcerative colitis.

Standard leukocytapheresis (LCAP) protocols recommend the processing of a 3 L blood volume. In this study, we evaluated the clinical effects of LCAP with 1.5 L of blood processing (1.5L-LCAP) in patients with active ulcerative colitis (UC). Ten patients with moderate to severe UC were enrolled. Their clinical and endoscopic responses, the kinetics of the peripheral blood counts and cytokine responses were evaluated. Clinical and endoscopic effects were assessed using the clinical activity index described by Rachmilewitz, and by Matts' endoscopic classification, respectively. The 1.5L-LCAP induced clinical remission in 8 out of 10 patients (80%). Endoscopic improvement was noted in 6 out of 7 patients (85.7%). Prednisolone (PSL) was used in 8 patients; the PSL dose could be reduced in 6 patients, and weaning was possible in one patient. Adverse effects were not observed during 1.5L-LCAP therapy. During the 1.5L-LCAP session, the leukocyte count reached the minimum at 1.0 L of blood processing, but promptly increased after completion of the session, and reached a maximum after 30 min. Interleukin (IL)-1beta-induced IL-8 and IL-6 secretion by peripheral blood mononuclear cells were both significantly reduced by 1.5L-LCAP therapy. 1.5L-LCAP was clinically effective for active UC patients. Cellular responses induced by 1.5L-LCAP were similar to those induced by a standard LCAP session.

Helicobacter pylori infection upregulates interleukin-18 production from gastric epithelial cells.

BACKGROUND: Helicobacter pylori infection induces a biased T helper type 1 (Th1) response that produces IFN-gamma and Fas ligand (FasL). Th1 cytokines are associated with apoptosis in the gastric epithelial cells. AIM: We aimed to define the role of the recently cloned IL-18, a IFN-gamma inducing factor, in gastric mucosal injury induced by H. pylori infection. METHODS: Twenty-seven gastric ulcer (GU) patients and 20 functional dyspepsia (FD) patients were enrolled in this study. Mucosal biopsy samples were obtained from the gastric antrum and GU site during endoscopy. Samples were used for histological examination, H. pylori culture and in-situ stimulation for 48 h in the presence of 10 microg/ml phytohemagglutinin-P. IL-18, IFN-gamma, and soluble FasL (sFasL) levels in culture supernatants were assayed by the enzyme-linked immunosorbent assay method. IL-18, IL-1beta-converting enzyme (ICE) and caspase-3 were evaluated by western blotting in gastric cancer cell lines (MKN45) cocultured with H. pylori. RESULTS: All 27 GU patients and ten out of 20 FD patients were found to be H. pylori-positive, whereas ten FD patients were H. pylori-negative. Antral mucosal tissues from H. pylori-positive FD patients contained (P<0.01) higher levels of IL-18, IFN-gamma, and sFasL than those from uninfected FD patients. IL-18, IFN-gamma, and sFasL levels at the ulcer site were significantly (P<0.01) higher than those at distant sites in the antrum. A significant relationship was seen between IL-18 and IFN-gamma levels at the ulcer site (r=0.7, P<0.01). H. pylori eradication led to a significant decrease in the levels of IL-18, IFN-gamma, and sFasL at the ulcer site. Western blotting showed that IL-18, ICE, and caspase-3 were activated in gastric cancer cell lines cocultured with H. pylori. CONCLUSION: This study suggests that H. pylori infection enhanced mucosal injury by stimulating a Th1 response, which was mediated by IL-18 upregulation as well as activation of ICE and caspase-3.

Anti-gp210 and anti-centromere antibodies are different risk factors for the progression of primary biliary cirrhosis.

UNLABELLED: The predictive role of antinuclear antibodies (ANAs) remains elusive in the long-term outcome of primary biliary cirrhosis (PBC). The progression of PBC was evaluated in association with ANAs using stepwise Cox proportional hazard regression and an unconditional stepwise logistic regression model based on the data of 276 biopsy-proven, definite PBC patients who have been registered to the National Hospital Organization Study Group for Liver Disease in Japan (NHOSLJ). When death of hepatic failure/liver transplantation (LT) was defined as an end-point, positive anti-gp210 antibodies (Hazard ratio (HR) = 6.742, 95% confidence interval (CI): 2.408, 18.877), the late stage (Scheuer's stage 3, 4) (HR = 4.285, 95% CI:1.682,10.913) and male sex (HR = 3.266, 95% CI: 1.321,8.075) were significant risk factors at the time of initial liver biopsy. When clinical progression to death of hepatic failure/LT (i.e., hepatic failure type progression) or to the development of esophageal varices or hepatocellular carcinoma without developing jaundice (Total bilirubin < 1.5 mg/dL) (i.e., portal hypertension type progression) was defined as an end-point in the early stage (Scheuer's stage 1, 2) PBC patients, positive anti-gp210 antibodies was a significant risk factor for hepatic failure type progression [odds ratio (OR) = 33.777, 95% CI: 5.930, 636.745], whereas positive anti-centromere antibodies was a significant risk factor for portal hypertension type progression (OR = 4.202, 95% CI: 1.307, 14.763). Histologically, positive anti-gp210 antibodies was most significantly associated with more severe interface hepatitis and lobular inflammation, whereas positive anticentromere antibodies was most significantly associated with more severe ductular reaction. CONCLUSION: These results indicate 2 different progression types in PBC, hepatic failure type and portal hypertension type progression, which may be represented by positive-anti-gp210 and positive-anticentromere antibodies, respectively.

A phase I study of S-1 administration and a 24-h infusion of cisplatin plus paclitaxel in patients with advanced gastric cancer.

OBJECTIVE: The objective of this study was to determine the dose-limiting toxicity (DLT), the maximum tolerated dose (MTD), the recommended dose (RD) and the preliminary antitumor activity of S-1, oral dihydropyrimidine dehydrogenase inhibitory fluoropyrimide, in combination with cisplatin and paclitaxel for advanced gastric cancer. PATIENTS AND METHODS: Paclitaxel was administered on day 1. A fixed dose of S-1 (70 mg/m2/day) was orally administered for 14 consecutive days from day 1 and a 24-h infusion of a fixed dose of cisplatin (60 mg/m2) was administered on day 14 of every 28-day cycle. Four dose escalation levels of paclitaxcel were studied (120, 140, 160 and 180 mg/m2). RESULTS: Twenty patients were enrolled. The toxicities were generally mild no grade 4 hematological toxicity or grade 3 non-hematological toxicity were observed. Level 4 was considered as the MTD because of a treatment delay of more than 2 weeks in 3 out of 6 patients. The RD of paclitaxcel was 160 mg/m2. The overall response rate was 75%. CONCLUSION: A triple combination chemotherapy consisting of S-1, cisplatin and paclitaxel showed a tolerable level of adverse reactions and favorable antitumor activity.

Long-term follow-up after eradication of Helicobacter pylori with omeprazole, clarithromycin, and tinidazole (OCT regimen) in a Japanese population.

BACKGROUND: The long-term benefit of Helicobacter pylori eradication treatment that includes metronidazole on peptic ulcer disease in Japan is unclear. We investigated the rate of H. pylori re-infection and ulcer relapse after H. pylori eradication. MATERIALS AND METHODS: A total of 266 patients with endoscopically confirmed peptic ulcer disease and H. pylori infection were treated with triple therapy of omeprazole 40 mg (20 mg b.i.d.), clarithromycin 800 mg (400 mg b.i.d.), and tinidazole 1000 mg (500 mg b.i.d.) for 7 days. Endoscopy with gastric biopsy was performed before and 1 month, 6 months, 1.5 years, and 3.5 years after therapy. H. pylori status was determined by H. pylori culture, rapid urease test, and histopathology. 13C-urea breath test was done at 6 months after eradication therapy. Treatment was deemed successful when all tests were negative at 6 months after therapy by endoscopic biopsy. RESULTS: Successful H. pylori eradication was achieved in 262/266 (98.5%) patients with peptic ulcer. Total relapse of peptic ulcer occurred in 8/262 (3%) patients after eradication, with 3/262 (1.1%) occurring within 1.5 years after treatment and 5/262 (1.9%) within 3.5 years. All relapsed patients were found to be H. pylori-positive at the time of relapse. Of the 262 patients who experienced eradication, 20 (7.6%) were subsequently re-infected, six (2.3%) within 1.5 years and 14 (5.3%) within 3.5 years. CONCLUSION: Triple therapy with omeprazole, clarithromycin, and tinidazole (OCT) is useful for H. pylori eradication in Japan, but there is an appreciable re-infection rate in this population.

Esophageal cancer with colonic metastasis successfully treated by chemoradiotherapy followed by chemotherapy with S-1 and cisplatin.

A 51-year-old man was hospitalized for evaluation of dysphagia and bloody stool. Gastrointestinal endoscopy showed esophageal cancer invading the gastric fundus. A metastatic lesion was demonstrated in the sigmoid colon. The patient agreed to have concurrent chemoradiotherapy for the primary lesion, followed by additional chemotherapy. The first course included 30 Gy of radiotherapy given over 3 weeks, together with daily oral administration of S-1 (80 mg/m2 per day) for 2 weeks, and a 24-h infusion of cisplatin (70 mg/m2) on day 8. After a second course of chemoradiotherapy, four additional courses of chemotherapy with S-1 and cisplatin were administered, at 4-week intervals. After the additional chemotherapy, gastroscopy and colonoscopy showed disappearance of both the primary and the metastatic lesions. One year after his initial hospitalization, no recurrence of either the primary or the metastatic tumor lesions is evident.

[A case of advanced cervical and upper thoracic esophageal carcinoma completely responding to chemoradiotherapy with TS-1 and cisplatin].

A 52-year-old man was hospitalized for evaluation of dysphagia. Esophagography depicted an irregular narrowing extending 7 cm from the cervical esophagus to the upper thoracic esophagus. Esophagoscopy with biopsy showed cervical esophageal cancer narrowing the lumen. Surgery was contraindicated because of a previous cardiac infarction. The patient selected concurrent chemoradiotherapy with TS-1 and cisplatin. The first course included 30 Gy of radiotherapy given over 3 weeks, together with daily oral administration of TS-1 (120 mg/day) for 2 weeks, and a 24-h infusion of cisplatin (70 mg/m2) on day 8. After a second course of chemoradiotherapy, 4 courses of chemotherapy with TS-1 and cisplatin were administered at 4-week intervals. After additional chemotherapy, esophagoscopy and cervical CT showed that the primary lesion had disappeared. Two years after initial hospitalization, no recurrence has been detected.

[A case of metastatic esophageal cancer responding remarkably to combination chemotherapy of TS-1 and cisplatin].

A 51-year-old male patient with esophageal cancer and cervical, thoracic and celiac artery lymph node metastases was treated by combination chemotherapy of TS-1 and cisplatin. TS-1 (80 mg/m2/day) was administered for 14 days followed by 14 days rest as 1 course. Cisplatin (70 mg/m2/day) was administered in 24-hour continuous intravenous infusion at day 8 after the start of TS-1. Before treatment, the tumor marker, CEA showed 27,060 ng/ml. After 5 courses of chemotherapy, endoscopy revealed that the primary tumor had disappeared and no cancer cells were detected by endoscopic biopsy. Chest and abdominal CT scan also showed almost total disappearance of the lymph nodes metastases. CEA decreased to 710 ng/ml. No high-grade toxicities (WHO grade 3 or 4) were seen during the chemotherapy. He is now very well. This TS-1/cisplatin chemotherapy regimen might be a useful treatment for metastatic esophageal cancer.
