BACKGROUND: The treatment of intramucosal early gastric cancer with undifferentiated-type histologies (UD-EGCs) using endoscopic submucosal dissection (ESD) is controversial. This study aimed to compare the clinical and oncologic long-term outcomes of ESD and surgery for UD-EGCs. METHODS: A prospectively collected database of patients who underwent ESD or surgery between January 2006 and December 2012 was established. Patients who diagnosed with UD-EGC and satisfied the expanded indications of ESD were included...

Background: The impact of age as a prognostic factor for patients with colorectal cancer (CRC) remains controversial, possibly due to heterogeneity between studies in terms of patient numbers, percentage of patients undergoing curative resection, percentage of patients receiving neoadjuvant therapy, or failure to adjust for potential confounding factors. This study used colorectal cancer survival data from the Taiwan Cancer Registry database in order to comprehensively analyze age as a prognostic factor...

Krukenberg tumor, defined as metastatic adenocarcinoma to the ovary containing at least 10% signet ring cells, usually arises from the stomach but can also originate from other sites. We reviewed 17 metastatic breast carcinomas to the ovary with signet ring cells to potentially identify features indicative of mammary origin as opposed to other possible primary sites. The patients ranged from 41 to 76 (mean, 53.6) yr. Fourteen had a prior history of invasive breast carcinoma (invasive ductal carcinoma, 4; invasive lobular carcinoma, 3; adenocarcinoma not otherwise specified, 3; carcinoma with ductal and lobular features, 2; and unspecified carcinoma, 2) and metastases were identified 2 to 284 (mean, 79) mo after the original diagnosis...

A 63-year-old woman underwent thyroidectomy for papillary thyroid adenocarcinoma and cervical lymph node resection. Pathological analyses revealed the presence of signet cell carcinoma in a resected lymph node, which were apparently different from the pathological findings of thyroid carcinoma. No evidence of a primary tumor could be found elsewhere despite detailed examinations, including esophagogastroduodenoscopy, colonoscopy, capsule endoscopy, CT scan, and fluorodeoxyglucose-positron emission tomography...

BACKGROUND: Early-onset colorectal cancer (E-CRC) is increasing in incidence, unlike traditional CRC (T-CRC). We sought to characterize differences between E-CRC and T-CRC. MATERIALS AND METHODS: Data sources included the Surveillance, Epidemiology, and End Results database, the Behavioral Risk Factor Surveillance Survey, and The Cancer Genome Atlas (TCGA). We compared demographics, tumor characteristics, and incidence of CRC in subjects aged 20 to 49 years (E-CRC) with those aged ≥ 50 years (T-CRC)...

Previously, in the Asian Cancer Research Group (ACRG) project, we defined four distinct molecular subtypes in gastric cancer (GC). Mesenchymal (microsatellite stable with epithelial-to-mesenchymal transition phenotype, MSS/EMT) tumors showed the worst prognosis among all the subtypes. To develop a gene signature for predicting mesenchymal subtype GC, we conducted gene expression profiling using a NanoString assay in 70 ACRG specimens. The gene signature was validated in an independent set obtained from the prospective Adjuvant chemoRadioTherapy In Stomach Tumor (ARTIST) trial...

Amelanotic signet ring cell melanoma is one of the rare variants of malignant melanoma. Here we are presenting a case of a 58-year-old female with chief complaints of swelling in the left sternal region/breast, and right cervical region. Contrast Enhanced CT scan showed the two well circumscribed lobular mass lesions with central necrosis in the left breast. The radiologist opined the lesions as intramammary nodes. Biopsy from the larger breast mass lesion showed a tumour with cells arranged in discohesive pattern less with hetrogenos morphology...

Microangiopathic hemolytic anemia (MAHA) originates from a mechanical injury of red cells, caused by vascular thrombosis or stenosis. Cancer is a cause of MAHA as a consequence of both chemotherapy and disseminated disease itself. Here we describe the case of a 60-year-old man who developed a signet-ring cell carcinoma originated from the intrahepatic bile ducts, complicated by bone marrow metastasis and MAHA.

Signet ring adenocarcinoma of the breast with synchronous metastasis to the gastrointestinal (GI) tract is a rare occurrence, typically presenting with abdominal pain, dyspepsia, or GI bleed. We report a case of metastatic breast cancer presenting with a complaint of anemia. A further diagnostic evaluation revealed generalized lymphadenopathy, nodular thickening of the urinary bladder wall, bone lesions, and enlarged pancreas. Biopsies from the lymph nodes, pancreatic biopsy, and bladder nodule all revealed a signet cell carcinoma...

SATB2 is a sensitive marker for colorectal adenocarcinomas. No study has investigated its diagnostic utility in metastatic Krukenberg tumors (MKTs) of the ovary. Here we performed immunohistochemical staining SATB2 in 70 MKTs of various origins (stomach 27, colorectum 13, appendix 20 including 19 metastatic adenocarcinomas ex goblet cell carcinoids [AdexGCC] and 1 conventional poorly differentiated carcinoma with signet ring cells, breast 5, bladder 3, lung 2) to assess its diagnostic utility. We also compared SATB2 with CDX2, CK7, CK20, chromogranin, and synaptophysin in MKTs of gastric origin (MKTs-stomach), those of colorectal origin (MKTs-colorectum) and those due to appendiceal AdexGCCs (MKT-AdexGCCs) for their sensitivity and specificity to distinguish these tumors...

The cytoprotective protein clusterin is often dysregulated during tumorigenesis, and in the stomach, upregulation of clusterin marks emergence of the oxyntic atrophy (loss of acid-producing parietal cells)-associated spasmolytic polypeptide-expressing metaplasia (SPEM). The hormone gastrin is important for normal function and maturation of the gastric oxyntic mucosa and hypergastrinemia might be involved in gastric carcinogenesis. Gastrin induces expression of clusterin in adenocarcinoma cells. In the present study, we examined the expression patterns and gastrin-mediated regulation of clusterin in gastric tissue from: humans; rats treated with proton pump (H+/K+-ATPase) inhibitors and/or a gastrin receptor (CCK2R) antagonist; H+/K+-ATPase β-subunit knockout (H/K-β KO) mice; and Mongolian gerbils infected with Helicobacter pylori and given a CCK2R antagonist...

BACKGROUND: To optimize outcome, selection of patients for cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is critical. Recently, Simkens et al.7 evaluated the peritoneal surface disease severity score (PSDSS) and suggested a new prognostic nomogram, the colorectal peritoneal metastases prognostic surgical score (COMPASS) based on age, peritoneal carcinomatosis index score, locoregional lymph node status, and signet ring cell histology. This COMPASS nomogram had better discriminative ability according to the Harrell c-index than PSDSS (c = 0...

BACKGROUND: Reports are limited regarding clinical and pretreatment features that might predict a pathological complete response (pathCR) after treatment in patients with esophageal cancer (EC). This might allow patient selection for different strategies. This study examines the association of a pathCR with pretreatment variables, overall survival (OS), recurrence-free survival (RFS), and patterns of recurrence in a large cohort from a single institution. METHODS: The baseline clinical features of 911 consecutive patients with EC who were treated with trimodality therapy from January 2000 to November 2013 were analyzed...

Pulmonary tumour thrombotic microangiopathy (PTTM) is a rare complication of cancer, which can be lethal due to progressive pulmonary hypertension (PH). Several case reports have demonstrated that imatinib, a platelet-derived growth factor receptor-tyrosine kinase inhibitor, can improve severe PH in patients with PTTM.We describe the case of a 56-year-old woman. Her mean pulmonary arterial pressure (mPAP) was 47 mm Hg, and her dyspnoea worsened rapidly over several days. Although pulmonary embolism was not observed on CT, enlargement of the para-aortic lymph nodes was detected...

A 63-year-old male with a recently diagnosed right lung lesion was referred for staging. F-FDG PET/CT scan revealed a hypodense, cystic-like mass in the right upper lung lobe, which demonstrated low, diffuse (18)F-FDG uptake, likely due to the presence of mucus, as well as intensely hypermetabolic right hilar and right paratracheal lymph nodes. Transbronchial biopsy revealed a primary pulmonary mucinous cystadenocarcinoma with the presence of signet ring cell carcinoma, a co-existence of two rare variants of lung adenocarcinoma...

AIMS: Genome-wide next-generation sequencing has revealed several driver mutations and allows establishing a molecular taxonomy of gastric cancer. However, correlation between the broad mutational spectrum of gastric cancer and its various clinicopathological characteristics has yet to be fully elucidated. METHODS AND RESULTS: Herein, we analyzed the mutational pattern of 77 genes in a cohort of 91 patients with poorly cohesive carcinoma using targeted sequencing and evaluated the clinicopathological significance of the various mutations based its histologic pattern, either signet ring cell (SRC) or other types of poorly cohesive carcinoma (not otherwise specified) (PCC-NOS)...
