RESULTS Patients with ECE(+) showed significantly worse 3-year overall survival (OS) and disease-free survival (DFS) than those without ECE. In the sensitivity analysis, ECE had independent prognostic value for both 3-year OS and 3-year DFS, whereas ECE grading showed little impact on mortality trend or disease progression trend. The ECE-based nomogram showed a significantly higher C-index than the pathological tumor and node staging (pTN) staging system. CONCLUSIONS The adverse prognostic impact of ECE was validated. Sub-serosal tumor deposits without recognizable lymph node tissue are recommended for inclusion in the ECE definition. A nomogram involving ECE could provide better individual prediction of survival for patients with lymph node-positive gastric cancer.BACKGROUND Remnant gastric cancer (RGC) has a major impact on the long-term survival of postgastrectomy patients. In this study, we established surveillance endoscopy guidelines for postgastrectomy patients based on the risk of RGC. PATIENTS AND METHODS A total of 6365 patients who underwent gastrectomy at Seoul St. Mary's Hospital from September 2005 to June 2018 were retrospectively reviewed; 85 patients were identified as having RGC. We divided the RGC patients into subgroups according to the interval between primary and secondary gastrectomy. RESULTS The curative resection rate was significantly lower in patients with an interval of ≤ 5 years versus > 5 years (p = 0.017). RGC developed more frequently after Billroth II reconstruction, and at the anastomotic site, in patients with a > 10- versus ≤ 10-year interval (p = 0.006 and p = 0.014, respectively). Similar results were observed based on the 15-year interval cutoff (p = 0.001 and 0.018, respectively). The 5-year overall survival rate of patients with a ≤ 5-year interval was significantly lower than that of patients with a > 5-year interval (60.0% versus 85.7%, p = 0.015), while overall survival did not differ between the ≤ 10- and > 10-year, or ≤ 15- and 15-year interval groups. RGC incidence showed a decrease after around 20 years postoperatively. CONCLUSIONS Thorough endoscopic examination should be conducted for up to 5 years postgastrectomy. Routine annual endoscopic follow-up should be performed for up to 20 years after the primary operation for gastric cancer, to allow for early detection of RGC.BACKGROUND Neuroendocrine neoplasia (NEN) are rare and heterogenous tumours. Few data exist on the impact of surgical therapy. MATERIALS AND METHODS This is a retrospective analysis of prospectively collected data of gastroenteropancreatic NEN in the German NET-Registry (1999-2012). It focuses on patients without distant metastases (limited disease, LD, stage I-IIIB). RESULTS Data of 2239 patients with NEN were recorded. Median age was 59 years, the gender ratio was 11.3 (fm). A total of 986 patients (44%) had LD, and the 5-year survival rate (5 years) was 77% for all and 90% for patients with LD. A total of 1635 patients (73%) received a surgical therapy (1st to 6th line); the 5 and 10 ysr were 83/65% after and 59/35% without surgery for all patients (p  less then  .001). The resection margins in the LD patients were 76%, 16%, and 3% for R0, R1 and R2, respectively. The 10 ysr was 84%, 59% and 42% for R0, R1 and R2 resections, respectively (p = .021 R0/R1, p  less then  .001 R0/R2). The R0 resection rate was 75% for G1/G2 NET and 67% for G3 NEC. CONCLUSION The rate of complete tumour resection (R0) in LD is independent of tumour grading, and R0 resection is the key determinant of long-term survival, as demonstrated by the 10 ysr. of 84%. All NEN patients with limited disease should be considered for operation, if possible, as the best 10-year survival is shown after an R0 resection.Corrosive (caustic) material ingestion remains a major health issue, particularly in developing countries. The management strategy after corrosive ingestion should be planned according to the signs and symptoms. The management of corrosive ingestion based on endoscopic grading, nothing by mouth, and barium studies should be abandoned. With the new management protocol, esophageal stricture can be predicted with high accuracy using the simple new prognostic DROOL score (≤ 4) rather than endoscopic grading, reduced by immediate oral feeding as soon as the patient can swallow saliva instead of nothing by mouth, diagnosed earlier (10-14 days) by fluoro-endoscopic balloon-assisted esophageal examination for patients with persistent dysphagia instead of relying on a barium study (≥ 21 days), and adequately treated by initiating balloon dilation earlier during the same anesthesia procedure. Fluoroscopically guided balloon dilatation with large balloons (18-20 mm) seems to be safe, with a low frequency of complications and a high success rate. BGJ398 If dilatation fails after a few months, esophagectomy and replacement surgery using the stomach should be considered. The increased risk of developing esophageal carcinoma after ingestion of corrosive substances should be kept in mind.BACKGROUND The focus of trastuzumab resistance biomarkers in recent decades has been on epigenetic and non-coding RNA-based mechanisms. In this study, the potential of miR-494 and its target genes as predictive biomarkers for breast cancer (BC) resistance to trastuzumab was identified. The microarray data were obtained from the GEO database, including GSE101841, GSE75669, and GSE66305. Data processing was conducted using GEO2R to obtain differentially expressed genes (DEGs). RESULTS The data analysis using GEO2R revealed that DEGs from GSE101841 and GSE75669 consisted of 3 and 135 upregulated miRNAs, respectively. On the other hand, the same analysis revealed 8 and 226 downregulated miRNAs for DEGs from GSE101841 and GSE75669, respectively. A Venn diagram showed that one miR was detectable in serum and tissue samples, namely miR-494. The miR-494 target was predicted using the miRecords database and resulted in 69 target genes. A Venn diagram between miR-494 target genes from miRecords and the mRNA array from GSE66305 revealed three potential targets of CNR1, RBM39, and ZNF207.
