Background: The expansion of function-preserving surgery became possible due to a more profound understanding of gastric cancer (GC), and T1N + or T2N + gastric cancer patients might be potential beneficiaries. However, ways to evaluate the possibility of function-preserving pylorus surgery are still unknown.

Methods: A total of 288 patients at Renji Hospital and 58 patients at Huadong Hospital, pathologically diagnosed with gastric cancer staging at T1 and T2 with tumors located in the upper two-thirds of the stomach, were retrospectively enrolled from March 2015 to October 2022.

Article Synopsis
  • * The research included 2,001 patients from 10 hospitals who underwent various treatments; findings revealed that CM significantly improved overall survival compared to standard treatments, with median survival times of 18.17 months for the CM cohort versus 12.45 months for the non-CM cohort.
  • * Factors such as mixed tumor type, more than 6 cycles of first-line treatment, use of CM, palliative surgery, and specific medications were identified as independent predictors of better survival outcomes.

Background: Long non-coding RNAs (lncRNAs) display regulatory function flexibly in tumor onset and developments. Our study aimed to delve into the roles of lncRNA LINC01569 (LINC01569) in colorectal cancer (CRC) progression to study the potential mechanisms.

Methods: The genetic expression profiles of miR-381-3p and LINC01569 were measured by RT-PCR.

In this study, we first obtained the complete mitochondrial genome of (Decapoda: Brachyura: Potamoidea). The genome is 16,965 bp in length and typically consists of 37 genes (13 protein-coding genes, 22 tRNAs genes, two rRNAs genes, and one putative control region). In addition, the mitogenome has 20 non-coding regions ranging from 1 to 683 bp in length.

Background: Injury to the vagus nerve has been proposed to be associated with occurrence of gallstones after gastrectomy. We investigated the effect of preservation of hepatic branch of the vagus nerve on prevention of gallstones during laparoscopic distal (LDG) and pylorus-preserving gastrectomy (LPPG).

Methods: Preservation of the vagus nerve was reviewed of cT1N0M0 gastric cancer patients underwent LDG (n = 323) and LPPG (n = 144) during 2016-2017.

There are still lot of controversies whether aberrant left hepatic artery (ALHA) originating from left gastric artery should be ligated or preserved during gastric cancer (GC) surgery. We aimed to investigate this issue. We reviewed ALHA cases who had laparoscopic gastrectomy for gastric cancer at Seoul National University Hospital (SNUH) from 2012 to 2016.

Background: Liver is one of the most preferred destinations of distant metastasis in gastric cancer (GC). As effective treatment is still limited, the prognosis of GC patients bearing liver metastasis is poor. We filter out lysyl oxidase (LOX) to study its function in the tumor microenvironment (TME) and seek for potential therapeutic targets.

We report the complete mitochondrial genome of for the first time, which is found to be 16,547 base pairs in length, and contains 13 protein-coding genes (PCGs), two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA), and one non-coding AT-rich region known as the D-loop. In addition, the mitogenome has 17 intergenic regions ranging from 1 to 1512 bp in length. The mitochondrial genome of is the first mitochondrial genome under the genus , providing DNA data for species identification, enriching the species diversity of Brachyura, and providing a basis for further studies on population genetics and phylogenetics.

Background: UCA1 is a long non-coding RNA which was found overexpressed in various human cancers including gastric cancer (GC). It is identified that UCA1 promotes GC cells proliferation, migration and invasion, however, the role of UCA1 during the processes of immune escape is still not unclear.

Methods: We collected 40 paired GC and non-tumor tissue samples.

Background: Gastric cancer is one of the deadliest malignant tumours, with a high incidence in China, and is regulated by aberrantly overexpressed oncogenes. However, existing therapies are insufficient to meet patients' needs; thus, the identification of additional therapeutic targets and exploration of the underlying mechanism are urgently needed. GPAA1 is the subunit of the GPI transamidase that transfers the GPI anchor to proteins within the ER.

Background: Pylorus-preserving gastrectomy (PPG) is commonly performed for early gastric cancer (EGC) located in middle third of the stomach. We investigated the surgical, oncological, and functional outcomes of PPG involving the upper third of stomach.

Methods: We included all patients of the period 2013-2016 who underwent PPG, distal subtotal gastrectomy (DSG), and total gastrectomy (TG) for EGC involving the upper third by carefully defining the localization.

Background: Delayed gastric emptying is one of the most disturbing complications of pylorus-preserving gastrectomy (PPG) and it increases hospital stay. We investigated the clinical outcome of intraoperative manual dilatation of the pylorus as a preventive method of pyloric spasm after PPG.

Materials And Methods: We reviewed gastric cancer patients who underwent PPG between January 2014 and December 2016 at Seoul National University Hospital by a single surgeon.

In this study, the authors first obtained the mitochondrial genome of Somanniathelphusa boyangensis. The results showed that the mitochondrial genome is 17,032bp in length, included 13 protein-coding genes, 2 rRNAs genes, 22 tRNAs genes and 1 putative control region, and it has the characteristics of the metazoan mitochondrial genome A+T bias. All tRNA genes display the typical clover-leaf secondary structure except tRNASer(AGN), which has lost the dihydroxyuridine arm.

Krt17 is a 48kDa protein member of keratin family. Previous literatures have demonstrated Krt17 may play a promotive role in the progression of various malignancies. However, the exact function of Krt17 in the carcinogenesis and the progression of gastric cancer (GC) remains unknown.

Single-cell analysis of heterogeneity has become the cutting-edge technology for profound understandings of relationships between cell populations. At present, common methods used in single cellular genomic research are mainly microfluidic technologies (Fluidigm) or based on microwells, both requiring a uniform size of cells at the entrance. However, the size of cells in specific tissues can vary from type to type.

Objective: To observe the expression of THY-1 (CD90) in gastric tumour cells and its effect on the growth of gastric cancer and to provide new evidence for the development of possible targets for the treatment of gastric cancer.

Methods: The effect of THY-1 on the proliferative ability of HGC-27, MGC-803 and AGS gastric cancer cells was examined by CCK-8 and cell cycle assays. The effect of THY-1 on the ability of gastric cancer cells to avoid apoptosis was analysed by Annexin V/PI double staining.

Background: FBXW7, a component of the Skp-Cullin1-F-box, mediates target protein recognition. It is a tumor suppressor gene that plays a role in the regulation of cell cycle exit and reentry via c-Myc, c-Jun and Notch degradation. There are few studies, particularly involving a large patient cohort, that have evaluated FBXW7 during gastric cancer progression.

Gastrointestinal stromal tumor (GIST) is the most major mesenchymal neoplasm of the digestive tract. Up to now, imatinib mesylate has been used as a standard first-line treatment for irresectable and metastasized GIST patients or adjuvant treatment for advanced GIST patients who received surgical resection. However, secondary resistance to imatinib usually happens, resulting in a major obstacle in GIST successful therapy.
