The death rate from gastric cancer decreased when endoscopic screening was used. Endoscopy is recommended as a population-based screening method for gastric cancer in regions or countries where mortality from this disease is high.
Patients receiving S-1 treatment should be evaluated for potential lacrimal disorders, particularly canalicular obstruction/stenosis. Dacryoendoscopic observation is effective for the diagnosis of this side effect.
Intussusception is a common cause of mechanical bowel obstruction among children, with older children being more likely to have a pathological lead point. Intestinal neoplasms are rare and small intestinal lipomas are even less common. Herein we describe a case of a 7-year-old boy with ileoileal intussusception, with an ileal lipoma as the pathological lead point. Computed tomography was useful pre-operatively for revealing intussusception due to lipoma as the pathologic lead point.
10 Background: Randomized phase III (ToGA trial) has demonstrated that the addition of trastuzumab to standard chemotherapy improved overall survival in patients (pts) with HER2-positive metastatic gastric cancer (mGC). In screening of the ToGA trial, HER2 positivity rate was 22.1 % in total, but the rates varies between countries. Therefore, to determine the HER2 incidence rate in Japanese mGC, we planned prospective cohort study JFMC44-1101. Methods: JFMC44-1101 is a multicenter epidemiological trial assessing HER2 status in Japan. Patients with histologically confirmed gastric adenocarcinoma, not suitable for curative resection were eligible. HER2 status was centrally assessed both immunohistochemistry (IHC) and fluorescence in-situ hybridization (FISH) using formalin fixed paraffin embedded (FFPE) tissues from tumor. HER2 positive is defined as either IHC3+ or FISH+ in accordance with ToGA trial. Overall and subgroup estimates calculated with 95%CI. Results: Between September 2011 to June 2012, 1466 pts were registered from 157 sites. Patients characteristics were; gender (M/F):1044/422, median age (min-max): 68 (25-99), advance / recurrence: 1068 / 398. Samples are 768 from biopsy and 698 from excision. In August 2012, 1427/1466 pts were assessed. Overall, HER2 positivity was 20.5% (293 pts). Each IHC status (0/1+/2+/3+) with FISH+ was 3.0% / 11.3% / 46.9% / 97.2%, respectively. The frequency of IHC 0/1+ with FISH+ was almost as high as IHC 2+ with FISH+ (5.6%/4.2%). HER2 positivity rate of background factors were; male/female:23.6%/14.3%, biopsy/ excision: 22.7%/19.0%, advance / recurrence: 21.6%/17.6%. Conclusions: JFMC44-1101 confirmed the incidence of HER2 positivity in Japanese mGC. HER2-positivity rate and HER2 status were similar to the ToGA screening population. Clinical trial information: UMIN000006190.
Background/Aim: To evaluate the utility of endoscopy for assessing radiation esophagitis during chemoradiotherapy (CRT) with proton beam therapy (PBT) boost for esophageal cancer. Methods: Between December 2012 and December 2016, 38 patients with esophageal cancer were treated with CRT with PBT boost. To evaluate radiation esophagitis, endoscopy was performed after administration of CRT with standard PBT boost (total dose 50-60 Gy relative biological effectiveness [RBE]). Radiation esophagitis was evaluated and classified into 5 newly developed endoscopic grades (Fukui Acute Radiation Esophagitis [FARE] grade). The additional PBT boost was then adjusted and delivered (2-20 Gy [RBE]) to a maximum total dose of 74.4 Gy (RBE) based on the degree of radiation esophagitis, probability of residual tumor, and patient's general condition. To evaluate the utility
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
