Short bevacizumab infusion as an effective and safe treatment for colorectal cancer. Mol Clin Oncol 2022; 17:139. [PMID: 35949896 PMCID: PMC9353868 DOI: 10.3892/mco.2022.2572] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2022] [Accepted: 07/12/2022] [Indexed: 11/30/2022] Open
Abstract
Bevacizumab is a humanized monoclonal antibody that contains <10% murine protein. To prevent infusion-related hypersensitivity reactions (HSRs), the initial bevacizumab infusion is delivered for 90 min, the second for 60 min and subsequent doses for 30 min. Several previous studies have shown that short bevacizumab infusions are safe and do not result in severe HSRs in patients with colorectal, lung, ovarian and brain cancer. However, the efficacy of short bevacizumab infusions for colorectal cancer management remains unclear. Therefore, to investigate this issue, a prospective multicenter study was conducted using 23 patients enrolled between June 2017 and March 2019. The initial infusion of bevacizumab was for 30 min followed by a second infusion rate of 0.5 mg/kg/min (5 mg/kg over 10 min and 7.5 mg/kg over 15 min. The primary endpoint was progression-free survival (PFS). The overall response and disease control rates were 57 and 87%, respectively. The median PFS time was 306 days (interquartile range, 204-743 days). No HSRs were noted. Adverse events associated with bevacizumab included grade 4 small intestinal perforation and grade 3 stroke in 1 patient each. These results suggest that a short bevacizumab infusion regime comprising an initial infusion for 30 min followed by a second infusion at 0.5 mg/kg/min is safe and efficacious for the management of colorectal cancer.

Generalizability of Eccentric Exercise for Patients with Subacromial Pain Syndrome to Real-world Clinical Practice: A Propensity Score-based Analysis. Prog Rehabil Med 2021; 6:20210019. [PMID: 33860110 PMCID: PMC8041652 DOI: 10.2490/prm.20210019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Accepted: 03/30/2021] [Indexed: 11/13/2022] Open
Abstract
Objectives: Subacromial pain syndrome is a common problem in primary care. Although several randomized controlled trials have shown that eccentric exercise is effective in patients with subacromial pain syndrome, its generalizability to real-world clinical practice is unknown. This study aimed to investigate, using propensity score analysis, the generalizability of eccentric exercise for patients with subacromial pain syndrome to real-world daily clinical practice. Methods: In this study, 78 patients underwent eccentric exercise in addition to traditional exercise, and 77 patients underwent only traditional exercise for 4 weeks. Outcomes measured using a visual analog scale (VAS) and American Shoulder and Elbow Surgeons Society Standardized Shoulder Assessment Form (ASES) scores were assessed at baseline and at 4 weeks. Results: In the propensity score-matched analysis, 65 patients in each group were successfully matched (130 of 155 patients, 84% overall). After 4 weeks of exercise, pain intensity was lower in the eccentric exercise group than in the traditional exercise group (VAS −14.5, 95% CI −21.2 to −7.9, P<0.001). No significant difference in the improvement in function was found between the two groups (ASES 4.1, 95% CI −2.0 to 10.2, P=0.18). Conclusions: Eccentric and traditional exercise in combination could reduce pain in patients with subacromial pain syndrome to a greater extent than traditional exercise alone. These findings have clinical relevance to primary care practitioners who provide conservative treatment for patients with subacromial pain syndrome.

Endoscopic findings of gastric lesions in patients with eosinophilic gastrointestinal disorders. Endosc Int Open 2020; 8:E1817-E1825. [PMID: 33269315 PMCID: PMC7676993 DOI: 10.1055/a-1268-7312] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2020] [Accepted: 09/03/2020] [Indexed: 02/07/2023] Open
Abstract
Background and study aims Eosinophilic gastrointestinal disorders are classified into eosinophilic esophagitis, eosinophilic gastritis, eosinophilic gastroenteritis, and eosinophilic colitis according to the site of eosinophilic infiltration. Although well established in eosinophilic esophagitis, endoscopic findings in eosinophilic gastritis and eosinophilic gastroenteritis with regard to gastric lesions have not been clearly described. The aim of this study was to identify endoscopic findings of gastric lesions associated with eosinophilic gastrointestinal disorders. Patients and methods Out of 278 patients with eosinophilic gastrointestinal disorders, 18 had eosinophilic gastritis or eosinophilic gastroenteritis confirmed by biopsy; their endoscopic images were analyzed retrospectively. The association between endoscopic findings and number of eosinophils in the gastric mucosa was investigated. Results Erythema was most frequently observed (72 %), followed by ulcers (39 %), discoloration (33 %), erosions (28 %), nodularity (28 %), and polyps (28 %). There were several unique endoscopic findings such as submucosal tumor-like deep large ulcers in three patients, antral Penthorum -like appearances (small nodules radially lined toward the pyloric ring) in three patients, "muskmelon-like appearances" (discolored mucosa-composed mesh pattern) in three patients, multiple white granular elevations in two patients, cracks (appearance of furrows similar to those in eosinophilic esophagitis) in five patients, and antral rings in one patient. No significant association was observed between endoscopic findings and number of gastric eosinophils. Conclusions Several unique endoscopic findings of gastric lesions were observed in patients with eosinophilic gastritis or eosinophilic gastroenteritis. Submucosal tumor-like ulcers, antral Penthorum -like appearances, muskmelon-like appearances, and cracks might be associated with eosinophilic gastrointestinal disorders.

Abstract
BACKGROUND AND AIMS Colorectal polyps are often detected during the insertion phase of colonoscopy but are commonly removed during the withdrawal phase. We aimed to investigate the clinical advantages of instant removal of colorectal polyps during the insertion phase to determine the appropriate strategy for polyps detected on insertion. METHODS This prospective, multicenter, randomized trial targeted patients with at least 1 left-sided polyp <10 mm in size detected unintentionally on endoscope insertion from April 2018 to March 2019. Patients were allocated to the following 2 groups: study group, consisting of patients who had polyp removal instantly on insertion, and control group, comprising patients who had the endoscope inserted to the cecum first and polyps removed subsequently on withdrawal. Carbon dioxide gas insufflation and cold polypectomy were applied to minimize the influences of polypectomy on endoscope insertion. Twenty advanced endoscopists from 7 community-based institutions participated in this trial. RESULTS Of 1451 patients enrolled, 220 patients were eligible for full assessment. Mean total procedure time was significantly shorter in the study group (18.9 vs 22.3 minutes, P < .001). Mean pure cecal intubation time and number of polyps per patient were similar between the 2 groups. In the control group, among 107 polyps found during insertion, 48 (45.8%) required reinspection and 7 (6.5%) were completely missed, with an average reinspection time of approximately 3 minutes. CONCLUSIONS Polypectomy during the insertion phase in the colon and rectum significantly shortens the total procedure time and eliminates all missed polyps without experiencing any disadvantages.

Abstract
Background
Liver disease has emerged as an important cause of cystic fibrosis (CF)-associated morbidity due to recent advancements in management and a resultant increase in life expectancy. Although focal biliary cirrhosis remains the pathognomonic finding in CF, other hepatic manifestations exist but are not as well described, particularly in the pediatric population.
Aims
Present two rare manifestations of pediatric CF-associated liver disease.
Methods
In this report, we present a pediatric CF patient with chronic abdominal pain who was found to have hepatolithiasis, cholangitis and secondary sclerosing cholangitis.
Results
A 12-year-old boy with CF was seen for abdominal pain with functional impairment. He had prior evidence of calculi in the common bile duct (CBD) and right intrahepatic (IH) duct, and had undergone endoscopic retrograde cholangiopancreatography (ERCP) twice with sphincterotomy once. Magnetic resonance cholangiopancreatography (MRCP) at presentation showed dilated CBD and bilateral IH ducts with calculi, evidence of acute cholecystitis and early cholangitis. He subsequently underwent a third ERCP with stone retrieval, stent placement and a laparoscopic cholecystectomy. Ursodiol dose was optimized and antibiotics were initiated.
Follow-up MRCP showed improvement in CBD and IH duct dilation; the stent was removed. One month later, a fifth ERCP was performed for worsening symptoms associated with a distal filling defect in the left IH duct. Sludge was removed from the CBD and another stent was placed. A sixth ERCP with stent removal showed no stones.
Interval MRCP showed resolution of IH calculi, a CBD filling defect suggestive of sludge, and thickening and enhancement of IH bile ducts with focal areas of alternating narrowing and dilation. He was maintained on antibiotics, and his symptoms persisted over the following months despite resolution of sludge, peri-portal edema and duct-wall enhancement. There was a background of increased IH ductal dilation with “beaded appearance”. Interval imaging has demonstrated persistence of these findings with recurrence of hepatolithiasis in both IH ducts, despite improved symptoms.
Conclusions
This case describes two rare manifestations of pediatric CF-associated liver disease: hepatolithiasis and secondary sclerosing cholangitis. While CFTR dysfunction alone predisposes to gallstone formation, the patient’s clinical course supports a theory for the development of hepatolithiasis resembling that of recurrent pyogenic cholangitis, whereby bacteriobilia from chronic or recurrent infection may promote lithogenesis in the presence of inflammatory bile duct damage. In this patient, secondary sclerosing cholangitis may have resulted from cycles of cholangitis and hepatolithiasis; alternatively, it may represent under-recognized cholangiopathy in the pediatric CF population.

Abstract
Distinct anatomic variants of the scapula such as the critical shoulder angle (CSA) were found to be associated with rotator cuff tears (RCTs), but it is unclear whether the CSA is a risk factor in Japanese. Here we sought to determine whether the CSA is associated with RCTs in a Japanese population, and whether the CSA is a more useful parameter than the conventionally used parameters. Our RCT group and non-RCT group each consisted of 54 consecutive cases. We compared the groups' values of CSA, the acromion index (AI), and the lateral acromion angle (LAA) obtained by X-ray imaging. Receiver operating characteristic (ROC) analyses were performed to determine cutoff values and the area under the curve (AUC), and to assess the odds ratio. The means of the CSA and the AI in the RCT group were significantly larger (36.3° vs. 33.7°, 0.74 vs 0.68), but the LAA did not show a significant between-group difference. The AUCs for the CSA and AI were 0.678 and 0.658, the cutoff values were 35.0° and 0.72, and the odds ratios were 3.1 and 2.5, respectively. In conclusion, the CSA was a strong risk factor compared to the AI and LAA for rotator cuff tears.

Abstract
BACKGROUND AND AIM The Japan narrow-band imaging (NBI) Expert Team (JNET) was organized to unify four previous magnifying NBI classifications (the Sano, Hiroshima, Showa, and Jikei classifications). The JNET working group created criteria (referred to as the NBI scale) for evaluation of vessel pattern (VP) and surface pattern (SP). We conducted a multicenter validation study of the NBI scale to develop the JNET classification of colorectal lesions. METHODS Twenty-five expert JNET colonoscopists read 100 still NBI images with and without magnification on the web to evaluate the NBI findings and necessity of the each criterion for the final diagnosis. RESULTS Surface pattern in magnifying NBI images was necessary for diagnosis of polyps in more than 60% of cases, whereas VP was required in around 90%. Univariate/multivariate analysis of candidate findings in the NBI scale identified three for type 2B (variable caliber of vessels, irregular distribution of vessels, and irregular or obscure surface pattern), and three for type 3 (loose vessel area, interruption of thick vessel, and amorphous areas of surface pattern). Evaluation of the diagnostic performance for these three findings in combination showed that the sensitivity for types 2B and 3 was highest (44.9% and 54.7%, respectively), and that the specificity for type 3 was acceptable (97.4%) when any one of the three findings was evident. We found that the macroscopic type (polypoid or non-polypoid) had a minor influence on the key diagnostic performance for types 2B and 3. CONCLUSION Based on the present data, we reached a consensus for developing the JNET classification.

Abstract
BACKGROUND Interruption of sedation due to a poor response to modified neuroleptanalgesia (m-NLA) with midazolam often occurs during endoscopic submucosal dissection (ESD) for esophageal squamous cell carcinoma (ESCC) because most patients have a history of heavy alcohol intake. Recently, propofol has been used feasibly and safely during endoscopic procedures. The aim of this study was to clarify the efficacy and safety of propofol compared with that of midazolam during ESD for ESCC. METHODS This was a single-blind, randomized controlled trial in a single center. Patients with ESCC scheduled for ESD were included in the study. Patients were randomly assigned to one of two groups: the propofol group and the midazolam group. The main outcome was the incidence of discontinuation of the procedure due to a poor response to sedation. Secondary outcomes included risk factors for a poor response to sedation. RESULTS Between April 2014 and October 2015, 132 patients (n = 66 per group) who underwent ESD for ESCC were enrolled in this study. The incidence of discontinuation due to a poor response to sedation in the propofol and midazolam groups was 0% (0/66) and 37.9% (25/66), respectively (p < 0.01). Multivariate analyses revealed that use of midazolam [Odds ratio (OR), 7.61; 95% confidence interval (CI), 2.64-21.92; p < 0.01] and age (OR, 0.93; 95% CI, 0.86-0.98; p < 0.01) were risk factors for a poor response to sedation. CONCLUSIONS Our study indicates that, compared with midazolam, propofol is a more efficient sedative for m-NLA during ESD for ESCC.

Abstract
It has been unclear whether the risk factors for rotator cuff tears are the same at all ages or differ between young and older populations. In this study, we examined the risk factors for rotator cuff tears using classification and regression tree analysis as methods of nonlinear regression analysis. There were 65 patients in the rotator cuff tears group and 45 patients in the intact rotator cuff group. Classification and regression tree analysis was performed to predict rotator cuff tears. The target factor was rotator cuff tears; explanatory variables were age, sex, trauma, and critical shoulder angle≥35°. In the results of classification and regression tree analysis, the tree was divided at age 64. For patients aged≥64, the tree was divided at trauma. For patients aged<64, the tree was divided at critical shoulder angle≥35°. The odds ratio for critical shoulder angle≥35° was significant for all ages (5.89), and for patients aged<64 (10.3) while trauma was only a significant factor for patients aged≥64 (5.13). Age, trauma, and critical shoulder angle≥35° were related to rotator cuff tears in this study. However, these risk factors showed different trends according to age group, not a linear relationship.

Abstract
OBJECTIVE To examine characteristics and survival outcomes of women with surgically-treated cervical cancer exhibiting uterine corpus tumor invasion. METHODS We utilized The Surveillance, Epidemiology, and End Results Program to identify cervical cancer patients who underwent hysterectomy between 1973 and 2003. Logistic regression models were used to identify risk factors for uterine corpus tumor invasion on multivariable analysis. Association of uterine corpus tumor invasion and cause-specific survival (CSS) from cervical cancer was examined with Cox proportional hazard regression models on multivariable analysis. RESULTS We identified 837 (4.9%) cases of uterine corpus invasion and 16,237 (95.1%) cases of non-invasion. Median follow-up time was 14.0 years. There were 1642 deaths due to cervical cancer. Uterine corpus invasion was independently associated with older age, non-squamous histology, high-grade tumors, large tumor size, and nodal metastasis on multivariable analysis (all, P < 0.001). On univariable analysis, uterine corpus tumor invasion was significantly associated with decreased CSS compared to the non-invasion (5-year rates, 79.0% versus 94.5%, P < 0.001). After controlling for other significant prognostic factors, uterine corpus tumor invasion remained an independent prognostic factor for decreased CSS (adjusted-hazard ratio 1.45, 95% confidence interval 1.21-1.74). Among stage T1b cases (n = 6730), uterine corpus tumor invasion remained an independent prognostic factor for decreased CSS (adjusted-hazard ratio 1.95, 95%CI 1.47-2.60). Uterine corpus tumor invasion was significantly associated with decreased CSS in stage T1b1 disease (74.5% versus 90.7%, P < 0.001) and in stage T1b2 disease (67.0% versus 79.5%, P = 0.01). CONCLUSION Uterine corpus tumor invasion is an independent prognostic factor for decreased survival of women with early-stage cervical cancer.

Narrow-band imaging (NBI) magnifying endoscopic classification of colorectal tumors proposed by the Japan NBI Expert Team. Dig Endosc 2016; 28:526-33. [PMID: 26927367 DOI: 10.1111/den.12644] [Citation(s) in RCA: 316] [Impact Index Per Article: 39.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2015] [Revised: 02/17/2016] [Accepted: 02/25/2016] [Indexed: 12/11/2022]
Abstract
Many clinical studies on narrow-band imaging (NBI) magnifying endoscopy classifications advocated so far in Japan (Sano, Hiroshima, Showa, and Jikei classifications) have reported the usefulness of NBI magnifying endoscopy for qualitative and quantitative diagnosis of colorectal lesions. However, discussions at professional meetings have raised issues such as: (i) the presence of multiple terms for the same or similar findings; (ii) the necessity of including surface patterns in magnifying endoscopic classifications; and (iii) differences in the NBI findings in elevated and superficial lesions. To resolve these problems, the Japan NBI Expert Team (JNET) was constituted with the aim of establishing a universal NBI magnifying endoscopic classification for colorectal tumors (JNET classification) in 2011. Consensus was reached on this classification using the modified Delphi method, and this classification was proposed in June 2014. The JNET classification consists of four categories of vessel and surface pattern (i.e. Types 1, 2A, 2B, and 3). Types 1, 2A, 2B, and 3 are correlated with the histopathological findings of hyperplastic polyp/sessile serrated polyp (SSP), low-grade intramucosal neoplasia, high-grade intramucosal neoplasia/shallow submucosal invasive cancer, and deep submucosal invasive cancer, respectively.

Abstract
5′- O-Alkyl derivatives of 1-β-D-arabinofuranosyl- E-5-(2-bromovinyl)uracil (BV-araU) were synthesized by selective alkylation and deprotection of 2′,3′-bis- O-tetrahydropyranyl BV-araU to enhance metabolic stability and evaluated for efficacy as oral prodrugs of BV-araU. For comparison, their acyl congeners, and 3′- O- and 2′- O-ethyl BV-araU, were also prepared by direct acylation of BV-araU and by selective protection, alkylation, and deprotection, respectively. The 5′- O-alkyl prodrugs were stable in acidic solutions, whereas the 5′- O-acyl analogues were unstable under the same conditions. When incubated with enterobacteria, the 5′- O-acyl derivatives resulted in the formation of BV-uracil through non-enzymatic hydrolysis of BV-araU, but the 5′- O-alkyl prodrugs did not. 5′- O-Short-chain aliphatic alkyl (not longer than butyl) and generally acyl prodrugs gave higher blood concentrations of BV-araU than the aromatic derivatives. Plasma concentrations of BV-araU were equal or slightly higher than those after equivalent oral doses of BV-araU. 5′- O-Ethyl BV-araU was effective against intracerebral, intraperitoneal, and cutaneous infections with herpes simplex virus type 1 in mice. 5′- O-Short-chain aliphatic alkyl derivatives may prove to be useful oral prodrugs of BV-araU because of increased metabolic stability.

Abstract
New pyrimidine deoxyribonucleoside analogues, 2′-deoxy-2′-methylideneuridine (DMDU), 2′-deoxy-2′-methylidenecytidine (DMDC), and their 5-substituted derivatives were tested for the anti-herpesvirus activities and anti-proliferative activity. E-5-(2-Bromovinyl)uracil derivative (BV-DMDU) and its cytosine congener were synthesized from 1-β-D-arabinofuranosyl- E-5-(2-bromovinyl)uracil (BV-araU). 5-Bromo, 5-iodo, 5-methyl, and 5-ethyl derivatives of DMDU and BV-DMDU showed activities against herpes simplex virus type 1 (HSV-1) and varicella-zoster virus (VZV). The corresponding DMDC derivatives had no or only weak antiviral activity. Among the 2′-deoxy-2′-methylidene pyrimidine nucleosides, BV-DMDU showed the most potent and selective anti-VZV activity. BV-DMDU was more potent than acyclovir, but less active than BV-araU. BV-DMDU was inactive against human diploid and tumour cells. DMDC and F-DMDC (5-fluoro derivative) were potent inhibitors of HSV-1, herpes simplex virus type 2, VZV, and human cytomegalovirus (HCMV) and also had significant anti-proliferative activity. Their potency against HCMV was better than that of ganciclovir and araC. Some DMDU derivatives also showed anti-HCMV activity, but they had anti-proliferative activity. The anti-HCMV activity of these DMDC and DMDU compounds was generally more potent than those against HSV-1 and VZV thereof, suggesting the participation of cellular kinase in their antiviral action.

Abstract
OBJECTIVE Once gastrointestinal (GI) graft-versus-host disease (GVHD) occurs after hematopoietic stem cell transplantation, it may be life-threatening. Therefore, an earlier accurate diagnosis of macroscopic and microscopic features using an appropriate modality improves the prognosis of patients with suspected GI-GVHD. PATIENTS AND METHODS In patients experiencing watery diarrhea within 100 days after hematopoietic stem cell transplantation, we evaluated the severity of mucosal injury at the proximal ileum, terminal ileum, and rectum according to previously reported criteria using transanal single balloon endoscopy. GI-GVHD was diagnosed by the presence of gland apoptosis without inflammatory or infectious factors in the biopsied specimens obtained from their respective site regardless of the mucosal lesion. RESULTS Consecutive suspected GI-GVHD patients with watery diarrhea (11 men and 5 women, mean age: 45.6 years, coexistent symptoms: nausea [38%] and exanthema [69%]) were enrolled. GI-GVHD was identified pathologically in 11 patients (69%), all of whom had pathological findings of GI-GVHD at the rectum. However, eight patients (73%) had pathological findings of GI-GVHD at both the ileum and the rectum and none had pathological findings of GI-GVHD at the ileum alone. The accuracies for a pathological diagnosis of GI-GVHD based on endoscopic features were 44%, 44%, and 38% at the proximal ileum, terminal ileum, and rectum, respectively. The severity of mucosal injury had no association with the diagnostic rate of pathological GI-GVHD at any site. CONCLUSIONS A pathological evaluation of the rectum but not the ileum may be important and useful for the accurate diagnosis of early GI-GVHD.

Abstract
BACKGROUND To examine the effect of the histology of carcinoma and sarcoma components on survival outcome of uterine carcinosarcoma. PATIENTS AND METHODS A multicenter retrospective study was conducted to examine uterine carcinosarcoma cases that underwent primary surgical staging. Archived slides were examined and histologic patterns were grouped based on carcinoma (low-grade versus high-grade) and sarcoma (homologous versus heterologous) components, correlating to clinico-pathological demographics and outcomes. RESULTS Among 1192 cases identified, 906 cases were evaluated for histologic patterns (carcinoma/sarcoma) with high-grade/homologous (40.8%) being the most common type followed by high-grade/heterologous (30.9%), low-grade/homologous (18.0%), and low-grade/heterologous (10.3%). On multivariate analysis, high-grade/heterologous (5-year rate, 34.0%, P = 0.024) and high-grade/homologous (45.8%, P = 0.017) but not low-grade/heterologous (50.6%, P = 0.089) were independently associated with decreased progression-free survival (PFS) compared with low-grade/homologous (60.3%). In addition, older age, residual disease at surgery, large tumor, sarcoma dominance, deep myometrial invasion, lymphovascular space invasion, and advanced-stage disease were independently associated with decreased PFS (all, P < 0.01). Both postoperative chemotherapy (5-year rates, 48.6% versus 39.0%, P < 0.001) and radiotherapy (50.1% versus 44.1%, P = 0.007) were significantly associated with improved PFS in univariate analysis. However, on multivariate analysis, only postoperative chemotherapy remained an independent predictor for improved PFS [hazard ratio (HR) 0.34, 95% confidence interval (CI) 0.27-0.43, P < 0.001]. On univariate analysis, significant treatment benefits for PFS were seen with ifosfamide for low-grade carcinoma (82.0% versus 49.8%, P = 0.001), platinum for high-grade carcinoma (46.9% versus 32.4%, P = 0.034) and homologous sarcoma (53.1% versus 38.2%, P = 0.017), and anthracycline for heterologous sarcoma (66.2% versus 39.3%, P = 0.005). Conversely, platinum, taxane, and anthracycline for low-grade carcinoma, and anthracycline for homologous sarcoma had no effect on PFS compared with non-chemotherapy group (all, P > 0.05). On multivariate analysis, ifosfamide for low-grade/homologous (HR 0.21, 95% CI 0.07-0.63, P = 0.005), platinum for high-grade/homologous (HR 0.36, 95% CI 0.22-0.60, P < 0.001), and anthracycline for high-grade/heterologous (HR 0.30, 95% CI 0.14-0.62, P = 0.001) remained independent predictors for improved PFS. Analyses of 1096 metastatic sites showed that carcinoma components tended to spread lymphatically, while sarcoma components tended to spread loco-regionally (P < 0.001). CONCLUSION Characterization of histologic pattern provides valuable information in the management of uterine carcinosarcoma.

Efficacy and safety of 1-week Helicobacter pylori eradication therapy and 7-week rebamipide treatment after endoscopic submucosal dissection of early gastric cancer in comparison with 8-week PPI standard treatment: a randomized, controlled, prospective, multicenter study. Gastric Cancer 2015; 18:612-7. [PMID: 25098924 DOI: 10.1007/s10120-014-0404-9] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/05/2014] [Accepted: 07/13/2014] [Indexed: 02/07/2023]
Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) has been developed for early gastric cancer (EGC). Helicobacter pylori eradication therapy has been reported to have a preventive effect against metachronous recurrence of EGC after ESD. However, the efficacy and safety of eradication therapy on ESD-induced ulcer healing are not clear. In a randomized control study, we compared the standard therapy (8-week proton pump inhibitor) and eradication therapy combined with subsequent treatment with 7-week rebamipide for healing ESD-induced ulcers. METHODS A multicenter, randomized, open-label study was conducted. In group A, patients received 20 mg of omeprazole for 56 days. In group B, patients received 40 mg of omeprazole, 1,500 mg of amoxicillin, and 800 mg of clarithromycin for 7 days, and then 300 mg of rebamipide for 49 days. The primary end point was to evaluate the scarring ratio. RESULTS The scarring rate in group A was significantly higher than that in group B [85.0 % (34/40) vs. 56.8 % (21/37), P = 0.011]. The scarring rate of ulcers with an area ≥565.5 mm(2) in group A was significantly higher than that in group B [78.9 % (15/19) vs. 37.5 % (6/16), P = 0.018]. There was no significant difference between the groups in the scarring rate of smaller ulcers. No serious adverse events were observed in any of the patients in either group. CONCLUSION H. pylori eradication therapy and 7-week rebamipide monotherapy were not superior to PPI monotherapy, but this combination therapy for smaller sized ulcers was an optimal therapeutic option for healing. Serious adverse events were not observed in either group.

Diagnostic performance and limitations of magnifying narrow-band imaging in screening endoscopy of early gastric cancer: a prospective multicenter feasibility study. Gastric Cancer 2014; 17:669-79.

Abstract
BACKGROUND Curative treatment of patients with gastric cancer requires reliable detection of early gastric cancer. Magnifying endoscopy with narrow-band imaging (M-NBI) is useful for the accurate preoperative diagnosis of early gastric cancer. However, the role of M-NBI in screening endoscopy has not been established. The aims of this study were to determine the feasibility and limitations of M-NBI in screening endoscopy. METHODS We conducted a multicenter prospective uncontrolled trial of patients undergoing routine screening endoscopy patients. We determined the diagnostic accuracy, sensitivity and specificity of M-NBI according to the degree of certainty and need for biopsy, as assessed using the VS (vessel plus surface) classification system. We analyzed the endoscopic and histopathological characteristics of both false negative and false positive high confidence M-NBI diagnoses. We then developed a provisional diagnostic strategy based on the diagnostic performance and limitations identified in this study. RESULTS A total of 1097 patients were enrolled in the study. We analyzed 371 detected lesions (20 cancers and 351 non-cancers). The accuracy, sensitivity and specificity of high confidence M-NBI diagnoses were 98.1, 85.7 and 99.4 %, respectively. The false negative case was a pale mucosal lesion with tissue diagnosis of signet-ring cell carcinoma. Exclusion of pale mucosal lesions increased the accuracy, sensitivity and specificity of high confidence M-NBI diagnoses to 99.4, 100 and 99.4 %, respectively. We therefore propose a practical strategy targeting non-pale mucosal lesions. CONCLUSIONS With a refined strategy considering its limitations, M-NBI can act as an "optical biopsy" in screening endoscopies.

Abstract
BACKGROUND There are few comprehensive reports detailing the prevalence of major adverse events associated with a double-balloon enteroscopy procedure. METHODS We retrospectively investigated the prevalence of major adverse events in 538 patients (262 males and 276 females; median age, 65 years; age range, 12-95 years) who underwent double-balloon enteroscopy at our Institution between April 2008 and October 2011. RESULTS Of the 17 adverse events recorded (3.2%), acute pancreatitis (n=5; 0.9%) occurred during both diagnostic (n=3) and therapeutic (n=2) anterograde double-balloon enteroscopy, and all of them were treated conservatively. For these cases, the average duration of the examination was 135 min, which was longer than for the other patients (97 min) (P=0.046). Intestinal bleeding (1.3%) was observed in 6 cases after endoscopic polypectomy and in 1 case following a biopsy procedure during a diagnostic double-balloon enteroscopy. The prevalence rates of intestinal perforation and other complications were 0.2% and 0.7%, respectively. CONCLUSIONS The rate of adverse events associated with double-balloon enteroscopy was high compared to that associated with conventional upper/lower gastrointestinal endoscopy (0.042%/0.078%). The occurrence of acute pancreatitis may be significantly dependent on the duration of double-balloon enteroscopy examination.

Abstract
Background and Study Aims There are a few reports about the efficacy of endoscopic submucosal dissection (ESD) for adenocarcinomas of the esophagogastric junction (EGJ). However, there is no detailed analysis that divides EGJ cancers into Barrett's adenocarcinoma and gastric cardia adenocarcinoma. The aim of this study was to analyze the efficacy of ESD for EGJ cancers, comparing these two adenocarcinomas. Patients and Methods This study included 43 patients who underwent ESD for type II EGJ cancers between 2004 and 2011. Pathological examination of resected specimens confirmed 14 cases of Barrett's adenocarcinoma and 29 cases of gastric cardia adenocarcinoma. Cutting margins on the oral side were placed 1 cm from the squamocolumnar junction, or 1 cm away from the slight elevation that is an endoscopic sign of subsquamous carcinoma extension. Clinical outcomes, prevalence and length of subsquamous carcinoma extension, and long-term outcomes were compared between these two types of adenocarcinoma. Results No significant differences in clinical outcomes were found between these two types of adenocarcinoma (en bloc, 100 % versus 100 %; complete, 100 % versus 89.7 %; curative, 85.7 % versus 75.9 %). No serious adverse events were encountered. The prevalence of subsquamous carcinoma extension was significantly higher in Barrett's adenocarcinoma compared with gastric cardia adenocarcinoma. Local and distant recurrence were not observed in any cases with curative resection during the follow-up period (1.6 - 87.6 months). Conclusion ESD for EGJ cancers, including both Barrett's adenocarcinoma and gastric cardia adenocarcinoma, was efficient and useful. ESD with a 1 cm safety margin may be acceptable for EGJ cancers.

Abstract
OBJECTIVE. Enteric bacteria play a significant role in the pathogenesis of non-steroidal anti-inflammatory drug (NSAID)-induced small intestinal damage. However, the association between small intestinal bacterial overgrowth (SIBO) and NSAID-induced small intestinal damage remains unclear. The aim of the study was to examine the association between SIBO and the presence of NSAID-induced severe small intestinal damage or its symptoms in chronic NSAID users. MATERIALS AND METHODS. Forty-three patients who had been using NSAIDs for over 3 months were enrolled. They were examined by capsule endoscopy and a lactulose hydrogen breath test (LHBT). We defined severe small intestinal damage as the presence of more than four small erosions or large erosions/ulcers. The LHBT result was considered positive if there was an increase in the level of breath hydrogen gas of >20 ppm above baseline. RESULTS. Out of 43 patients, 22 (51%) had severe small intestinal damage. The LHBT was positive in 5 of 21 patients (24%) without severe small intestinal damage and in 13 of 21 patients (59%) with severe small intestinal damage. Multiple logistic regression analysis showed that an LHBT-positive result was significantly associated with increased odds ratio for severe small intestinal damage (OR, 6.54; 95% CI, 1.40-30.50). There was no significant difference in the presence of symptoms between the LHBT-positive and LHBT-negative patients with severe small intestinal damage. CONCLUSION. SIBO might have a role in the development of severe small intestinal damage in chronic NSAID users.

Abstract
BACKGROUND/AIMS Visceral obesity is commonly involved in the pathogenesis of gastroesophageal reflux disease (GERD) and non-alcoholic fatty liver disease (NAFLD). However, other characteristic factors different from visceral obesity are associated with the pathogenesis of NAFLD. We investigated the prevalence of GERD symptoms in patients with NAFLD and its associated risk factors. METHODS NAFLD (n = 96) and controls (n = 139) were enrolled in this study. GERD symptoms were evaluated by using a frequency scale for the symptoms of GERD. RESULTS GERD symptom score and its prevalence rate were higher in the NAFLD group (7.4 ± 0.7, 37%) than those seen in the control groups (4.5 ± 0.4, 20%), which was independent of sex, age, and body mass index (BMI). GERD symptoms were correlated with insulin resistance (r = 0.167, p = 0.011), total cholesterol (T-CHO) (r = 0.138, p = 0.034), triglyceride (TG) (r = 0.178, p = 0.006), or immunoreactive insulin (r = 0.173, p = 0.008) but not BMI (r = 0.089, p = 0.175). GERD symptoms of the NAFLD group were significantly severer in the higher group of T-CHO and TG levels than those in the lower group. Multivariate analysis proved that risk factors related to GERD symptoms were TG (OR 3.96, 95% CI 1.31-11.9) and T-CHO (OR 3.39, 95% CI 1.11-10.3). CONCLUSION The severity and prevalence of GERD symptoms in patients with NAFLD were high, which was associated with serum levels of TG and T-CHO but not BMI.

Abstract
A 59-year-old woman and a 69-year-old man had esophageal strictures that were refractory to over 10 therapeutic attempts with endoscopic balloon dilation (EBD) after endoscopic submucosal dissections (ESD) for superficial esophageal carcinoma (SEC). The strictured lesions in both patients improved remarkably with a new endoscopic modality (endoscopic radial incision and cutting [ERIC]), which was carried out one to three times, and stricture recurrence was not noted throughout the follow-up period. ERIC is a safe and efficient method for treating refractory strictures after EBD caused by ESD for SEC.

Abstract
BACKGROUND AND PURPOSE Improved CTA delineation of arteries and unruptured aneurysms is clinically desired in the posterior fossa. We present a novel model-based iterative reconstruction that models system statistics and optics to improve CT image quality. We investigated the utility of MBIR for improving delineation of arteries in the posterior fossa on 3D brain CTA. MATERIALS AND METHODS Using filtered back-projection with a standard kernel and MBIR, we reconstructed axial images of 0.625-mm thickness of 28 consecutive patients (14 men; mean age, 58.6 ± 14.6 years) who underwent 64-detector brain CTA. We placed regions of interest on the axial images, measured the mean CT value in the basilar artery and the value and SD in the pons and bilateral cerebellar hemispheres, and calculated the contrast-to-noise ratio of the brain arteries in the posterior fossa. Using volume-rendered CTA and a 4-point scale, 2 radiologists independently graded delineation of the BA, bilateral vertebral artery, superior cerebellar artery, and anterior and posterior inferior cerebellar arteries. We compared the results between FBP and MBIR by using paired t and Wilcoxon signed-rank tests. RESULTS Compared with FBP, MBIR significantly improved the contrast-to-noise ratio (P < .0001) and subjective delineation of all arteries in the posterior fossa except the BA (VA, SCA, AICA, and PICA; P < .05 for all). The mean visual score by MBIR was 3.0 or higher for all those arteries except the AICA assessed by reader 1 (2.6 ± 0.7). CONCLUSIONS With 3D brain CTA, contrast-to-noise ratio and arterial delineation of the VA, SCA, AICA, and PICA in the posterior fossa are better with MBIR than FBP.

Abstract
PURPOSE To investigate treatment outcomes of uterine carcinosarcoma (CS) patients who underwent complete surgical resection of all visible disease and platinum-based adjuvant chemotherapy (multimodal therapy). MATERIALS AND METHODS The authors reviewed 127 uterine CS patients treated at this institution from 1990 to 2010. They operated 123 patients in clinical Stages 1-3, 97 of which underwent complete resection and systemic lymphadenectomy. RESULTS A total of 97 patients (FIGO 2008: Stage 1 in 50 patients, Stage 2 in six, Stage 3 in 37, and Stage 4 in four) underwent surgical staging, 74 of which were administered five cycles (median) of platinum-based adjuvant chemotherapy. The median overall survival (OS) associated with multimodal therapy 50.6 months compared with 34.9 months incomplete multimodal therapy. After multimodal treatment, 32.9% (32/97) patients showed recurrence (24/32 hematogenous). CONCLUSION Multimodal therapy increased survival among uterine CS patients, but the recurrence rate remained high. Further consideration of treatment options for uterine CS is required.

Abstract
This prospective study aimed to evaluate the feasibility and safety of locoregional mitomycin C (MMC) injection to treat refractory esophageal strictures after endoscopic submucosal dissection (ESD) for superficial esophageal carcinoma. Patients with dysphagia and strictures that were refractory to repeated endoscopic balloon dilation (EBD) were eligible. After EBD, MMC was injected into the dilated site. Between June 2009 and August 2010, five patients were recruited. The treatment was performed once in two patients and twice in three patients with recurrent dysphagia or restenosis. In all patients, passing a standard endoscope through the site was easy and the dysphagia grade improved (grade 3→1 in 3 patients, grade 4→2 in 2 patients). No serious complications were noted. During the observation period of 4.8 months, neither recurrent dysphagia nor re-stricture appeared in any of the patients. The combination of locoregional MMC injections and EBD is feasible and safe for the treatment of esophageal strictures after ESD.Recently, endoscopic submucosal dissection (ESD) has been developed and accepted as a new endoscopic treatment for gastrointestinal tumors. ESD is a promising treatment for superficial esophageal carcinoma (SEC), and it has a reliable en bloc resection rate. However, the application of ESD for widespread lesions is challenging because of the high risk of the development of severe strictures, which lead to a low quality of life after ESD. Although endoscopic balloon dilation (EBD) is effective for benign strictures, it needs to be performed frequently until the dysphagia disappears 1. Mitomycin C (MMC), which is a chemotherapeutic agent derived from some Streptomyces species 2, reduces scar formation when topically applied to a surgical lesion. MMC has been applied to treat strictures in a variety of anatomical locations, including a variety of organs 3. The aim of this study was to prospectively evaluate both the feasibility and the safety of locoregional MMC injection therapy in patients with refractory esophageal strictures after ESD for SEC.

Abstract
The incidence of fibrous dysplasia (FD) is not frequent in the case of benign bone tumors of the chest wall, and differential diagnosis between FD and the malignancy on the basis of imaging findings is difficult. We report a case of a painful FD lesion (size, 9×8 cm) that originated from the 5th rib of a 52-year-old man and was surgically resected. His symptoms improved after the operation. Painful and large FD lesions should be resected because of a difficulty in differential diagnosis from malignant tumors.

Abstract
BACKGROUND AND AIM Proton-pump inhibitor (PPI) therapy is the first-line treatment for gastroesophageal reflux disease; however, there are some reports of PPI failure in cases of non-erosive reflux disease (NERD). Among the pathogenic factors associated with PPI-refractory NERD, reflux other than acid reflux can not be detected by conventional pH monitoring. The purpose of this study was to clarify the usefulness of multichannel intraluminal impedance-pH (MII-pH) monitoring for PPI-refractory NERD patients and examine the pathogenesis. METHODS We used MII-pH monitoring to examine 29 PPI-refractory NERD patients on PPI treatment. Reflux parameters, symptom index (SI: positive if ≥ 50%), and proximal migration were analyzed. The acidity of the reflux was divided into acid (nadir pH ≤ 4) and non-acid (nadir pH > 4). Subjects were classified into reflux-related disease (abnormal reflux parameters or positive SI) and non-reflux-related disease (normal reflux parameters and negative SI). RESULTS Of the 29 subjects, 21 were diagnosed with reflux-related disease, including 6 with acid reflux type and 15 with non-acid reflux type, and 8 were diagnosed with non-reflux-related disease. Of the total 1816 liquid reflux episodes, 834 showed proximal migration, which was more common in symptomatic reflux than in asymptomatic reflux. CONCLUSIONS MII-pH monitoring could distinguish reflux-related disease (especially non-acid type) from PPI-refractory NERD. Proximal migration was associated with symptomatic reflux in PPI-refractory NERD patients.

Internal hypoechoic feature by EUS as a possible predictive marker for the enlargement potential of gastric GI stromal tumors. Gastrointest Endosc 2012; 75:731-8. [PMID: 22281109 DOI: 10.1016/j.gie.2011.10.036] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2011] [Accepted: 10/25/2011] [Indexed: 12/18/2022]
Abstract
BACKGROUND There is no clinical predictor for the enlargement potential of gastric GI stromal tumors (GISTs) during the follow-up observation period. OBJECTIVE The aim of our study was to identify predictive markers for the enlargement potential of gastric GISTs on the basis of various endosonographic features determined at the initial examination. DESIGN Single-center retrospective analysis. SETTING Academic university hospital in Japan. PATIENTS All patients (n = 74) with histologically diagnosed GISTs in the stomach underwent EUS. INTERVENTION EUS. MAIN OUTCOME MEASUREMENTS We analyzed the following endoscopic and EUS features: mucosal ulceration, irregular shape, irregular border, heterogeneity, internal hyperechoic spot, hypoechoic area, and anechoic area of gastric GISTs in 3 groups according to tumor size. Furthermore, we compared the characteristics between increased growth and unchanged growth of GISTs, that were defined on the basis of the novel tumor growth index: changes in tumor volume/follow-up interval (days between initial EUS and second EUS) (mm(3)/day). RESULTS The presence of heterogeneity (P = .016) and anechoic area (P = .003) was significantly highest in the group with the largest tumor size. The increased growth group had a higher presence of hypoechoic area than did the unchanged growth group (84.2% vs 51.9%, P = .023). Multivariate analysis showed that the presence of a hypoechoic area was an enlargement-associated factor (odds ratio 5.38; 95% confidence interval 1.19-24.39; P = .029). LIMITATIONS Retrospective design of the study. CONCLUSIONS The internal hypoechoic area determined by EUS may be a predictor for the enlargement potential of gastric GISTs.
