Choice of treatment was mainly determined by subjects’ Helicobacter status. Those infected with Helicobacter were given a course

of proton pump inhibitor (PPI)-based http://www.selleckchem.com/products/lapatinib.html triple therapy for one week to eradicate the microbe as first-line therapy. Those, who were free of Helicobacter infection, were mainly treated with single-agent chemotherapy. In early phase Inhibitors,research,lifescience,medical of the study period, a few patients underwent gastrectomy, which was a prevalent treatment at that time, as first-line or second-line therapy. No subject received radiotherapy or Rituximab in this series. After initiation of treatment, oesophageogastroduodenoscopy (OGD) was performed periodically until endoscopic and histological remission. If there was persistent histological evidence of EMZBL-MALT, according to endoscopic appearance, any subsequent large

cell transformation and patients’ preference, either a “wait-and-watch” approach with regular OGD monitoring or referral to Inhibitors,research,lifescience,medical other units for more aggressive treatment (e.g., combination chemotherapy or gastrectomy) would be made. All subjects were provided with long-term follow-up Inhibitors,research,lifescience,medical in CMC unless they were referred to oncology centers, defaulted follow-up or died. After disease remission, OGD would be arranged from time to time as surveillance and once suspicion of relapse was raised. Statistical analysis was performed using SAS 9.1.3 software package. Overall contain survival was calculated from Inhibitors,research,lifescience,medical time of diagnosis to time of death of any cause or last follow-up. Survival curves were estimated by the method of Kaplan-Meier. P values of 0.05 or less were taken as statistically significant. Results Characteristics Inhibitors,research,lifescience,medical of patients 30 subjects with gastric EMZBL-MALT were included in this study. In all cases, gastric biopsies for initial diagnosis were obtained through OGD. The median follow-up time was 6.4 years (IQR 3.9 to 8.9 years). At

time of diagnosis, median age was 71.5 years (IQR 64 to 81 years). Systemic B symptoms and beta-2-microglobulin level were not checked in most subjects and its significance could not be analyzed. Helicobacter was identified in 20 subjects Anacetrapib (67%), including 19 HP infection and 1 H. Heilmanni infection. Of these 20 subjects, Helicobacter was missed in gastric biopsies from first OGD in 3 subjects, who were subsequently diagnosed to have Helicobacter infection in second OGD. Characteristics of patients are summarized in Table 1. Table 1 Clinical characteristics Treatment outcome Only 29 patients received treatment and one patient, whose gastric biopsy did not demonstrate Helicobacter, refused any kind of treatment in view of advanced age (92 year old).
