Whether presence or history of extracolonic primary malignancy is a risk for colorectal neoplasia is not fully known. In this study, 26,452 first-time colonoscopy cases were examined using a colonoscopy database. Among the analyzed subjects, 3,026 (11%) subjects had history or concomitance of extracolonic primary malignancy, while the remaining 23,426 subjects did not. Colorectal neoplasia was ...

Volumetric laser endomicroscopy (VLE) is an advanced endoscopic imaging technique that provides high-resolution mucosal and submucosal images of the esophagus. VLE has been used in surveillance Barrett's esophagus (BE) patients undergoing treatment BE neoplasia. Several image-interpretation scoring systems have developed tested. Advances system, such as addition color to areas image marking muc...

BACKGROUND AND AIMS Obesity is a risk factor for colorectal neoplasia. We examined the influence of obesity and metabolic syndrome (MetS) on prevalence of neoplasia at screening colonoscopy. METHODS We evaluated 2020 subjects undergoing first screening colonoscopy. Body mass index (BMI) was calculated at enrolment. Hyperlipidemia (HL), hypertension (HT), and diabetes mellitus (DM) were identi...

AIM To assess the prevalence and location of advanced neoplasia in patients undergoing colonoscopy, and to compare the yield per indication. METHODS In a multicenter colonoscopy survey (n = 18 hospitals) in the Amsterdam area (Northern Holland), data of all colonoscopies performed during a three month period in 2005 were analyzed. The location and the histological features of all colonic neop...

El adenocarcinoma de células caliciformes o goblet cell carcinoma, es una neoplasia poco frecuente, reconocida por la OMS, que característicamente presenta componente mixto: exocrino y endocrino. Es un tumor casi exclusivo del apéndice cecal, pero se han reportado situaciones en las surge otros segmentos tubo digestivo. Se el caso hombre 86 años con extrapendicular colon derecho. estudio morfol...

The immunologic defense mechanism is well demon­trated in neoplasia of animals and human. Spontaneous regression of many human tumors such as malignant melanomas, 1vmphosarcomas, neuroblastomas choriocar­cinomas, adenocarcinomas and leukemias is due to the defense mechanism of lymphoretrcular system. The discovery of carcinoembrvonicantigen in carcinoma of gastrointestinal tract and the alpha-f...

This retrospective study surveyed the histological prevalence of 180 canine neoplasms registered during 2016-2020 in small animal hospital, Rajamangala University Technology Tawan-Ok, Chonburi, Thailand. Histopathologic diagnosis each neoplasia was performed using its published criteria. The were categorized into epithelial, mesenchymal and round-cell neoplasms. Their parameters related to sex,...

Introduction: Gallbladder carcinoma is the most common biliary tract carcinoma. A subset develops in polypoidal precursors that are detectable by ultrasound but not reliably distinguishable from non-neoplastic polyps. Most guidelines recommend cholecystectomy for polyps ≥ 10mm based on a higher rate of neoplasia, however, disagreements exist with management recommendations smaller incidentally ...

BACKGROUND Siblings and other first-degree relatives of patients with "sporadic" (i.e., apparently nonfamilial) colorectal cancer or precursor adenomatous colon polyps have an increased risk of developing colon neoplasia. This observation suggests the presence of inherited genetic determinants for sporadic colon neoplasia. Mice homozygous for a null cyclooxygenase 2 (COX2) (also called PTGS2) a...
