To analyze the available evidence on the role of treatment-oriented surgery in stage IV gastric cancer (metastatic disease), a systematic literature search was undertaken using Medline, Embase, Cochrane, and Web-of-Science libraries. The search was not restricted to articles published within a given year range. Articles written in English language (or with abstracts written in English) were considered. All references in the chosen articles were further screened to find additional relevant publications. Both clinical series and literature reviews were included. Stage IV gastric cancer is classified into four subcategories: positive peritoneal cytology without clear macroscopic peritoneal involvement (surgery is usually performed in these cases); gross appearance peritoneal carcinomatosis [surgery, eventually with hyperthermic intraoperative peritoneal chemotherapy (HIPEC) may be considered in very selected cases with limited PCI]; nodal metastases outside the loco-regional nodes (surgery may not be denied for metastatic nodes in stations 13 and 16); and hematogenous metastases (surgery should be performed in selected cases with liver metastases suitable to R0 resection). The analysis incorporated the new biological classification of stage IV gastric cancer recently proposed by Japanese researchers (Yoshida et al. in Gastric Cancer 19:329-338. https://doi.org/10.1007/s10120-015-0575-z , 2015) into the four aforementioned subcategories to make the comparison of the issues discussed meaningful. The take home message from the existing literature is that treatment-oriented surgery may be performed in a significant proportion of patients with stage IV gastric cancer.

Background: Different anesthetic drugs and techniques may affect survival outcomes for gastric cancer (GC) after surgery. In this study, we investigated the association between sedated and unsedated gastroscopy on survival outcomes in patients with GC after surgery.
Methods: This was a retrospective study of patients who were diagnosed with GC by gastroscopy and underwent gastrectomy from January 2013 to December 2017.

Background: The standard adjuvant chemotherapy regimen for stage III gastric cancer is docetaxel plus S-1 (DS) based on the results of the START-II trials. However, in clinical practice some patients could not continue this intensive doublet chemotherapy because of limited tolerability. This study aimed to assess the practical feasibility of DS and elucidate the predictive factors for the completion of adjuvant DS therapy.

Purpose: To identify the epithelial cell centre regulatory transcription factors in the gastric cancer (GC) microenvironment and provide a new strategy for the diagnosis and treatment of GC.
Methods: The GC single-cell dataset was downloaded from the Gene Expression Omnibus (GEO) database. The regulatory mechanisms of transcription factors in both pan-cancer and GC microenvironments were analysed using the Cancer Genome Atlas (TGCA) database.

Background/aim: Remnant stomach influx (RSI) from the anastomotic jejunal-remnant stomach, a physiological food passage, develops after proximal gastrectomy with double-tract reconstruction (PGDT). Sometimes, food passes into the jejunal-loop (JL). We investigated the association of the food passage route in PGDT (RSI/JL) with postoperative esophageal reflux and malnutrition.

Laparoscopic exploration (LE) is crucial for diagnosing intra-abdominal metastasis (IAM) in advanced gastric cancer (GC). However, overlooking single, tiny, and occult IAM lesions during LE can severely affect the treatment and prognosis due to surgeons' visual misinterpretations. To address this, we developed the artificial intelligence laparoscopic exploration system (AiLES) to recognize IAM lesions with various metastatic extents and locations.
