The aim of the project was to determine any effect of hyperbaric air on Bacteroides fragilis strains cultivated under hyperbaric conditions. Previously, it was hypothesized that there was a correlation between the presence of Bacteroides bacteria in patients preferring a meaty diet and cancer of the small intestine, and particularly of the large intestine and rectum. With respect to the fact that Bacteroides fragilis (BAFR) group are important producers of endotoxins, measurement and statistical evaluation of endotoxin production by individual strains of isolated Bacteroides species were used to compare bacteria isolated from various clinical samples from patients with colon and rectum cancer in comparison with strains isolated from other non-cancer diagnoses...

Several markers of pancreatobiliary lineage have been described in the literature. However, none have demonstrated sufficient specificity and sensitivity to warrant diagnostic use. We evaluated the utility of T-complex-associated-testis-expressed 3 (TCTE3) as a pancreatobiliary marker. A set of 247 adenocarcinomas from the gastrointestinal (GI) tract was identified including 18 from the gastroesophageal junction (GEJ), 29 stomach, 17 ampullary, 62 pancreatic, and 16 common bile duct and gallbladder (CBD/GB), 13 non-ampullary small intestine, 32 colon, and 24 rectum...

We report 2 unusual cases of Stage IV rectal cancer for which pathological complete response was achieved with neoadjuvant chemotherapy(NAC)consisting of a combination of 5-fluorouracil(5-FU), oxaliplatin, Leucovorin(mFOLFOX6)or irinotecan(FOLFIRI), and bevacizumab, without radiotherapy. Case 1: A 65-year-old man was diagnosed as having rectal cancer with an invasive carcinoma of the prostate and lymph node metastasis. He refused to undergo surgery and received NAC instead. After NAC with mFOLFOX6 and FOLFIRI was performed, CT scan and colonoscopy revealed no evidence of disease...

We present the case of a 61-year-old patient with local residual neoplasia (LRN) of the rectum and the case of a 65-year-old patient with LRN of the cecum. In both cases, the lesion measured 25 mm in diameter and its center was fixed by submucosal fibrosis causing the non-lifting sign. For endoscopic treatment, which was uneventful,a combination of endoscopic mucosal resection (EMR) and full-thickness resection (FTR) was used. In both cases, histological examination showed completely resected tubular adenoma with HGIN...

Chia-Lin Chou, Chien-Jen Tseng, Yow-Ling Shiue
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...

PURPOSE: We propose a method of image-guided brachytherapy (IGBT) that combines MRI-based target volume delineation for the first fraction with CT datasets of subsequent fractions, using an automatic, applicator-based co-registration, and report our preliminary experience. MATERIALS AND METHODS: The MRI of the first fraction was used for the first brachytherapy planning. For each subsequent brachytherapy fraction, after the same applicator insertion, a new CT scan with the applicator in place was obtained...

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)...

Osseous metaplasia (OM) is rarely observed in colorectal cancer (incidence < 0.4% in rectal cancer), where it has a non-specific clinical presentation and unknown pathogenesis. Here, we report three cases of colorectal carcinoma with OM and propose a new hypothesis. All three patients (two males and one female) were Chinese and had different sites of colorectal carcinoma with OM: rectum, sigmoid colon, and appendix. The pathologic diagnoses were serrated adenocarcinoma; moderately to poorly differentiated adenocarcinoma with micropapillary carcinoma and cribriform comedo-type adenocarcinoma; and mucinous adenocarcinoma, respectively...

This study evaluated the intestinal anti-inflammatory effects of goat whey in a mouse model of colitis induced by 2,4-dinitrobenzenesulfonic acid that resembles human IBD. At a concentration of 4 g/kg/day, the goat whey improved the symptoms of intestinal inflammation, namely by decreasing the disease activity index, colonic weight/length, and leukocyte infiltration. Moreover, goat whey inhibited NF-κB p65 and p38 MAPK signaling pathways and consequently down-regulated the gene expression of various proinflammatory markers such as IL-1β, IL-6, IL-17, TNF-α, iNOS, MMP-9, ICAM-1...

Hodgkin lymphoma (HL) commonly presents as nodal disease, but in a subset of cases, the disease primarily develops in extranodal sites. Primary classical HL of the gastrointestinal (GI) tract is an extremely rare occurrence. Primary nature of the disease is confirmed after a complete lymphoma work up including chest radiograph, computed tomography scan, peripheral blood, and bone marrow studies. Only a few cases of primary GI lymphomas with limited immunohistochemical or molecular confirmation have been reported in literature...

Primary squamous cell carcinoma (SCC) of the rectum is a very rare entity making up to 0.1-0.25/1,000 cases of all colorectal cancers. Here, we present the case of an otherwise healthy 63-year-old female who presented with progressive pelvic discomfort, new onset constipation and a complex mass in presacral region on imaging which was proved to be poorly differentiated SCC of the rectum. The correct diagnosis was achieved by fine needle aspiration (FNA) via endoscopic ultrasound (EUS-guided FNA) as initial conventional colonoscopy failed to establish the diagnosis...

Neuroendocrine tumors can arise from any portion of the gastrointestinal tract including the colon and rectum. In the scope of all colon and rectal malignancies, they are a rare cause of colorectal carcinoma. Relating to their pluripotent neuroendocrine cellular origins these carcinomas can produce a variety of biologically active peptides with several resultant paraneoplastic syndromes. One of these paraneoplastic syndromes is the syndrome of inappropriate antidiuretic hormone (SIADH). In the SIADH, supraphysiologic levels of vasopressin (antidiuretic hormone, AVP) precipitates exorbitant free water retention and resultant electrolyte abnormalities, most notably hyponatremia...
