The relaxin family peptide receptor 4 (RXFP4) is a G protein-coupled receptor (GPCR) expressed in the colorectum with emerging roles in metabolism and appetite regulation. It is activated by its cognate ligand insulin-like peptide 5 (INSL5) that is expressed in enteroendocrine L cells in the gut. Whether other evolutionarily related peptides such as relaxin-2, relaxin-3, or INSL3 activate RXFP4 signal transduction mechanisms with a pattern similar to or distinct from INSL5 is still unclear. In this study, we compare the signaling pathways activated by various relaxin family peptides to INSL5...

Metastases to the female genital tract from gastric cancer are rare, but they significantly worsen the prognosis of such patients. The potential routes for metastasis to the female genital tract from gastric cancer include hematogenous spread, lymphatic spread and surface implantation. The rate of lymphatic metastasis to the ovary from gastric cancer has been reported to be higher compared with that from colorectal cancer. Uterine or Fallopian tube metastases are usually secondary to ovarian metastases, which are typically identified prior to the detection of gastric cancer in half of all synchronous cases, with complaints of abdominal distention, pain, palpable mass, or abnormal uterine bleeding...

BACKGROUND & AIMS: Nearly 20% of the global cancer burden can be linked to infectious agents. Fusobacterium nucleatum promotes tumor formation by epithelial cells via unclear mechanisms. We aimed to identify microRNAs (miRNAs) induced by F nucleatum and evaluate their ability to promote colorectal carcinogenesis in mice. METHODS: Colorectal cancer (CRC) cell lines were incubated with F nucleatum or control reagents and analyzed in proliferation and would healing assays...

Alcohol consumption is the third leading risk factor for disease and mortality in Europe. As evaluated by the International Agency for Research on Cancer (IARC) Monographs, a causal relationship is established for consumption of alcoholic beverages and cancers of the oral cavity, pharynx, larynx, oesophagus, liver, colorectum and female breast, even at low and moderate alcohol intakes. The higher the amount of alcohol consumed, the higher the risk of developing cancer. In Europe, an estimated 10% (95% CI: 7%-13%) of all cancer cases in men and 3% (95% CI: 1%-5%) of all cancer cases in women are attributable to alcohol consumption...

OBJECTIVES: Evidence suggests a possible role of Fusobacterium nucleatum in colorectal carcinogenesis, especially in right-sided proximal colorectum. Considering a change in bowel contents and microbiome from proximal to distal colorectal segments, we hypothesized that the proportion of colorectal carcinoma enriched with F. nucleatum might gradually increase along the bowel subsites from rectum to cecum. METHODS: A retrospective, cross-sectional analysis was conducted on 1,102 colon and rectal carcinomas in molecular pathological epidemiology databases of the Nurses' Health Study and the Health Professionals Follow-up Study...

Hypercholesterolemia resulting in atherosclerosis is associated with an increased risk of ischemic heart disease and colorectal cancer (CRC). However, the roles of apoliprotein (Apo) E (Apoe) and low-density lipoprotein (Ldl) receptor (Ldlr) in colorectal carcinogenesis have not yet been investigated. In this study, we examined the susceptibility of Apoe-deficient and Ldlr-deficient mice, which are genetic animal models of atherosclerosis to azoxymethane (AOM)/dextran sodium sulfate (DSS)-induced colorectal carcinogenesis...

Importance: State-specific information about the health burden of smoking is valuable because state-level initiatives are at the forefront of tobacco control. Smoking-attributable cancer mortality estimates are currently available nationally and by cancer, but not by state. Objective: To calculate the proportion of cancer deaths among adults 35 years and older that were attributable to cigarette smoking in 2014 in each state and the District of Columbia. Design, Setting, and Participants: The population-attributable fraction (PAF) of cancer deaths due to cigarette smoking was computed using relative risks for 12 smoking-related cancers (acute myeloid leukemia and cancers of the oral cavity and pharynx; esophagus; stomach; colorectum; liver; pancreas; larynx; trachea, lung, and bronchus; cervix uteri; kidney and renal pelvis; and urinary bladder) from large US prospective studies and state-specific smoking prevalence data from the Behavioral Risk Factor Surveillance System...

It is recommended that small (6-10 mm) lesions be treated with endoscopic resection (ER), while diminutive (≤ 5 mm) lesions are not currently an indication for ER according to the Japanese guidelines. The aim of this study was to evaluate the molecular alterations, and therefore treatment indications, in diminutive vs. small tubular adenoma (TA). We prospectively analyzed genetic instability, including microsatellite instability (MSI) and loss of heterozygosity, methylation status, KRAS/BRAF mutations, and Ki-67 staining in 96 TAs without a villous component...

Squamous cell carcinoma (SCC) of the anal canal is seldom diagnosed at an early stage. Chemoradiation therapy is a standard in Europe and the United States, though in squamous cell carcinoma there is no evidence-based therapy. In Japan, endoscopic submucosal dissection (ESD) is the standard minimally invasive treatment for early stage cancer of the digestive tract, including the colorectum. Therefore, if the lesion is diagnosed at an early stage, ESD may be selected for anal canal lesions. We experienced two cases of early stage anal canal cancer in which the diagnosis and the extent of the lesions were confirmed using magnifying endoscopy with narrow-band imaging (NBI), as well as performing ESD...

BACKGROUND: Colorectal laterally spreading tumors (LSTs) are classified into LST-Gs and LST-NGs, according to macroscopic findings. In the present study, we determined the genetic and epigenetic alterations within colorectal LSTs and protruding adenomas. METHODS: A crypt isolation method was used to isolate DNA from tumors and normal glands of 73 macroscopically verified colorectal LSTs (histologically defined adenomas; 38 LST-Gs and 35 LST-NGs) and 36 protruding adenomas...

Gastrointestinal follicular lymphoma (GI-FL) is a rare extranodal variant of follicular lymphoma (FL) that has been increasingly reported in the literature. An especially indolent course is linked to the disease after a lack of observed patient death in past studies. However, overall survival (OS) and associated prognostic factors remain unclear. A large population-based database was utilized to identify demographic and clinicopathologic characteristics of GI-FL, along with survival differences among primary sites...

This article offers a historical perspective on the discovery of 3 types of serrated colorectal polyps recognized in the past 60 years. The first to be discovered was the hyperplastic polyp, which is still the most commonly encountered serrated polyp. In the past 20 years, the carcinoma-associated sessile serrated adenoma/polyp has been recognized, but its diagnosis can be difficult owing to overlapping histologic features with hyperplastic polyps. Less is known about the third type, the traditional serrated adenoma, because it is far less common than the other 2 types, and its association with cancer is currently under investigation...

: Laterally spreading tumors (LST) are colorectal adenomas that develop into extremely large lesions with predominantly slow progression to cancer, depending on lesion subtype. Comparing and contrasting the molecular profiles of LSTs and colorectal cancers offers an opportunity to delineate key molecular alterations that drive malignant transformation in the colorectum. In a discovery cohort of 11 LSTs and paired normal mucosa, we performed a comprehensive and unbiased screen of the genome, epigenome, and transcriptome followed by bioinformatics integration of these data and validation in an additional 84 large, benign colorectal lesions...
