BACKGROUND: The WHO defines early gastric carcinoma (EGC) as invasive carcinoma up to the submucosal layer, regardless of nodal metastasis. The recent study results indicate that EGC varies in location, histology, nodal metastasis, and prognosis. SUMMARY: The heterogeneity in EGC may be related to various types of epithelial stem cells. The most important stem cells include Lgr5(+) cells at the base of a gastric unit in the antrum-pylorus-cardia, Mist1(+) cells at the isthmus/Troy(+) cells at the base in the corpus-fundus, and Sox2(+) cells at the base in almost all regions...

This report describes a rare case of invasive extramammary Paget disease of the vulva with signet ring cell morphology in a 58-yr-old woman with a history of signet ring cell carcinoma of the stomach. This case was initially misinterpreted as a metastatic gastric carcinoma to the vulva because an initial small, superficial biopsy specimen showed infiltration of signet ring cells in the dermis without intraepidermal Paget cells. However, a surgically resected specimen showed concordant immunophenotypes in both intraepidermal Paget cells and intradermal signet ring cell components with immunoreactivity to cytokeratin (CK) 7, CEA, and gross cystic disease fluid protein-15, and immunonegativity for CK20, MUC5AC, and MUC6...

Metastases to the colon are rare and a high-frequency primary region is the stomach. In cases of metastases to the colon, the morphological type of the metastatic region is mostly the infiltrating type of poorly differentiated or undifferentiated adenocarcinoma with lymph and blood vessel invasion. A case of cancer metastasis to the transverse colon that originated from advanced gastric cancer, which shows the difficulties in the precise diagnosis of metastases to the colon, is presented. In the present case, the gastric carcinoma was determined to be an advanced infiltrative ulcerative adenocarcinoma and the colon carcinoma was determined to be a superficial depressed adenocarcinoma...

BACKGROUND: We compared relapse-free survival (RFS) in gastric neuroendocrine carcinoma (WHO grade 3) and gastric carcinoma (GC). This is one of very few studies that compare the prognosis of poorly differentiated neuroendocrine carcinoma (WHO grade 3, G3 NEC) with that of GC. METHODS: Between 1996 and 2014, 63 patients were diagnosed with G3 NEC of the stomach and 56 with gastric neuroendocrine tumors (NETs) with GC at Asan Medical Center in Seoul, Korea. We also randomly selected 762 patients diagnosed with GC between 1999 and 2008...

BACKGROUND AND AIMS: The aim of this study was to determine the yield of endoscopic screening in first-degree relatives (FDRs) of CDH1-negative hereditary diffuse-type gastric cancer (HDGC) patients. METHODS: In this retrospective observational cohort study, in 2 expert centers in the Netherlands data were collected on FDRs from families fulfilling the international HDGC criteria that underwent endoscopic screening. Extensive inspection of the stomach was performed by gastroscopy, taking random and/or targeted stomach biopsy specimens to identify diffuse-type gastric cancer...

We aimed to analyze gastric signet ring cell (SRC) carcinoma subtypes by investigating gastric and intestinal phenotypic marker expression, and explore the relationship between phenotype and K-ras mutation. Immunohistochemistry was performed on 163 SRC carcinoma patient specimens to detect gastric (MUC1, MUC5AC, and MUC6) and intestinal (MUC2 and CDX2) phenotypic markers, and tumors were classified into gastric (G), intestinal (I), and gastrointestinal (GI) phenotypes. DNA was extracted from the formalin-fixed, paraffin-embedded tumor samples, and K-ras mutations in codons 12, 13, and 61 were identified using polymerase chain reaction-based direct DNA sequencing...

Recent data supports a potentially significant role for immune checkpoint inhibitors in the treatment of gastric cancer. However, there are few data on the clinical implications of immunotherapy markers in gastric signet-ring cell carcinoma (SRCC). We evaluated the expression of programmed cell death protein-1 (PD-1), programmed cell death ligand 1(PD-L1), infiltration by CD3+ T cell, microsatellite instability (MSI), and Epstein-Barr Virus (EBV), and the relationship of each factor to survival in 89 advanced SRCC patients...

BACKGROUND: 5-Aminolevulinic acid is a precursor of photosensitizing protoporphyrin IX and has been applied for photodynamic diagnosis of brain and bladder tumors with few side effects. Although most upper gastrointestinal tumors can be detected during photodynamic diagnosis, some tumors containing signet-ring cells cannot be visualized. Here, we aimed to assess whether proteins involved in the absorbance, activation, and turnover of protoporphyrin IX altered the fluorescence signal in gastric cancer...

Malignant infiltration of pia and arachnoid mater, referred to as leptomeningeal carcinomatosis (LMC), is a rare complication of gastric carcinoma. The most common underlying malignancy in patients with LMC are leukemia, breast cancer, lymphoma, and lung cancer. We report a case of gastric adenocarcinoma that presented with LMC in the absence of overt gastrointestinal signs or symptoms. A 56-year-old Hispanic woman presented to the hospital with a three-week history of intermittent headaches and visual blurring...

Breast cancer with stomach metastasis rare with an incidence of 1% or less among metastatic breast cancer patients. We experienced a case of breast cancer metastasizing to the stomach in 65-year-old female patient. She experienced dyspepsia and poor oral intake before visiting the clinic. Diffuse infiltration with nodular mucosal thickening of the stomach wall was observed, suggesting advanced gastric cancer based on gross endoscopic finding. Spread of poorly cohesive tumor cells in the gastric mucosa observed upon hematoxylin and eosin stain resembled signet ring cell carcinoma, but diffuse positive staining for GATA3 in immunohistochemical stain allowed for a conclusive diagnosis of breast cancer metastasizing to the stomach...

Inflammatory fibroid polyp (IFP) is a rare benign lesion of the gastrointestinal tract. We report a case of computed tomography (CT) imaging finding of a gastric IFP with massive fibrosis. CT scans showed thickening of submucosal layer with overlying mucosal hyperenhancement in the gastric antrum. The submucosal layer showed increased enhancement on delayed phase imaging. An antrectomy with gastroduodenostomy was performed because gastric cancer was suspected, particularly signet ring cell carcinoma. The histopathological diagnosis was an IFP with massive fibrosis...

Access to the bypassed portion of the stomach after Roux-en-Y gastric bypass remains a challenge. We present a case of 64-year-old woman who presented with gastric outlet obstruction. We used a novel endoscopic technique to access the bypassed stomach by creating a jejunogastrostomy using a specialized stent, which allowed the insertion of a pediatric gastroscope to examine the bypassed portion of the stomach. Stomach biopsies revealed poorly differentiated adenocarcinoma with signet cell features.

Up to 10% of patients with visceral malignancies develop skin metastases during their clinical course and these metastases constitute about 2% of all skin cancers. Skin metastasis may be the first sign of a clinically silent visceral cancer or represent recurrence of an internal malignancy. In both situations, they are associated with poor prognosis, which can partly be attributed to underdiagnosis. In this paper, a case of relapsing gastric adenocarcinoma, which manifested itself as asymptomatic cutaneous papules and nodules on a patient's head and neck, is reported and histopathological approach to the cutaneous lesions containing signet-ring cell is briefly reviewed...

BACKGROUND: Endoscopic submucosal dissection (ESD) is not considered an appropriate treatment for undifferentiated early gastric cancer (UEGC) due to the higher risk of nodal metastases. We aimed to investigate predictive factors for nodal metastases in UEGCs, determine whether the tumor histology is an independent factor for it, and explore whether ESD is applicable for UEGC. METHODS: We reviewed the medical records of 1837 patients who underwent curative gastrectomy for poorly differentiated adenocarcinoma, signet ring cell carcinoma, and a mixed type of both tumors between 2008 and 2012...

Outcomes of patients with gastric cancer who exhibit positive peritoneal lavage cytology findings (CY(+) ) vary by diagnostic methods because of quantitative and qualitative cancer cell diversity. This study sought to establish practical diagnostic criteria for performing curative resections, based on peritoneal lavage cytology findings in gastric cancer patients. We enrolled 1028 patients with gastric cancer who underwent R0/1 (n = 911) or R2 (n = 117) resections and analyzed relationships between cancer cell findings in peritoneal lavage fluid and clinicopathological factors in the R0/1 group...

An 80 year-old female presented with ductal breast carcinoma (stage II) three years ago, complained of asthenia and iron-deficiency anemia. No diagnosis was obtained after conventional endoscopy and iron supplements were indicated. Ten months later visible digestive hemorrhage was presented. Upper and lower endoscopy was repeated but non-diagnosis was obtained. Thus, video capsule endoscopy was indicated identifying a stenotic lesion arising in the mucosa of distal jejunum. Histopathological examination revealed a poorly mucinous differentiated signet-ring cell adenocarcinoma with an intense peri-tumoral lymphoid (Crohn´s-like lymphoid reaction) and lympho-vascular infiltration with no nodal metastases (pT3N0;7ª edition TNM classification)...

BACKGROUND: Gastric cancer is a heterogeneous disease with variable presentation between racial and ethnic groups. Staging laparoscopy (SL) detects occult metastases not visible on cross-sectional imaging and therefore improves staging. It remains unclear how differences in race and ethnicity affect disease presentation and the yield of SL. METHODS: We performed a retrospective review of a prospectively maintained database to identify patients with gastric cancer treated with curative intent at our institutions from 2008 to 2015...
