Prostaglandin E2 (PGE2) promotes colorectal carcinogenesis. Overall, systemic PGE2 production can be assessed by measuring its major metabolite, PGE-M, in urine. We examined the potential role of PGE-M as a biomarker for colorectal adenoma risk and chemopreventive response to anti-inflammatory drugs. We conducted a prospective case-control study nested within the Nurses' Health Study. Among wom...

Background and aims: Cyclooxygenase 2 (COX-2) expression in subepithelial macrophages of colorectal adenoma has been suggested as the first in a series of steps leading to colorectal tumorigenesis. We tested the hypothesis that chemokines released from human colorectal adenoma epithelium might be involved in COX-2 expression in macrophages of the lamina propria. Methods: Endoscopic samples of s...

BACKGROUND Lack of confidence in postpolypectomy surveillance guidelines may be a factor in the observed low adherence rates among providers. OBJECTIVE To assess the 2006 postpolypectomy colonoscopy surveillance guidelines, which recommend 3-year follow-up colonoscopy for individuals with high-risk adenomas (defined as > or =3 adenomas or any advanced adenomas) and 5- to 10-year follow-up for...

BACKGROUND & AIMS A previously published study by our group suggested that adenoma-like dysplasia-associated lesions or masses (DALMs) in ulcerative colitis (UC) may be treated adequately by polypectomy and continued endoscopic surveillance. The length of follow-up evaluation in these patients averaged only 42 months. The purpose of this study was to evaluate the long-term outcome of our previo...

A few studies have shown inconsistent results regarding the association between the visceral fat proportion and colorectal adenomas. We aimed to investigate the association between abdominal fat distribution measured by computed tomography (CT) and colon adenoma.A total of 336 participants underwent physical examination, blood tests, colonoscopy, and abdominal computed tomography at Chung-Ang U...

BACKGROUND AND STUDY AIMS Adenoma detection is a key objective of colonoscopy, particularly in the context of colorectal cancer screening. The aim of this observational study was to identify the technical colonoscopy factors associated with adenoma detection. PATIENTS AND METHODS The study analyzed data from the English Bowel Cancer Screening Programme. The indication for all colonoscopies wa...

OBJECTIVES To evaluate the immunohistochemical expression of estrogen receptors (ER) and progesterone receptors (PR) in colorectal adenoma and adenocarcinoma and to correlate this immunohistochemical expression with different clinicopathological parameters. METHODS The study was retrospectively designed. A total of 86 tissue samples, including 33 paraffin blocks from patients with colorectal ...

Canalicular adenomas are uncommon benign salivary gland neoplasms of the oral cavity. They are typically located on the upper lip, buccal mucosa and infrequently found on the palate and derived from minor salivary glands. Intra-mandibular localization of canalicular adenoma is extremely rare. Due to benign character of the tumour, canalicular adenomas rarely present with bone erosion. Histologi...
