Background: The oncologic behavior of mucinous adenocarcinoma (MA) of colorectal differs from non-mucinous adenocarcinoma (NMA). MA is more advanced at diagnosis and has a poorer prognosis than NMA. We aimed to evaluate prognostic factors and survival rate in patients with MA compared with NMA in Western Iran. Methods: During 2008-2015 in a retrospective study, 83 patients with CRC referred to...

AIMS Human telomerase reverse transcriptase (hTERT) is believed to a reliable marker for telomerase activity. The expression of telomerase activity has not been investigated in a consecutive series of patients with colorectal adenocarcinoma in North Queensland. The objective of this study was to evaluate the significance of hTERT mRNA expression in colorectal adenocarcinoma in North Queensland....

Colorectal carcinoma (CRC) is a common pathology in the adult population but remains very rare neoplasia childhood with delayed diagnosis and advanced stage grim prognosis that can be fatal, research regarding pediatric adenocarcinoma remain rare. IT represents approximately 1% of neoplasms. It usually associated predisposing genetic factors; this closely linked inheritance familial syndromes. ...

Cases of primary colorectal adenocarcinoma metastasized to the palatine tonsil are extremely rare. To the best of our knowledge, only 10 cases have thus far been previously documented in the English literature. A 37-year-old Chinese woman presented with a right palatine tonsil swelling and odynophagia 5 months after a surgical resection of rectal adenocarcinoma was performed. The patient underw...

To investigate the role of telomerase in the multistep Colorectal carcinogenesis, we examined telomerase activity in 31 adenomatous polyps and 22 paired cancer-normal mucosa specimens from non-hereditary nonpolyposis colorectal cancer patients. Telomerase activity was detected in 18% of normal mucosa, 16% of small «1.0 cm) polyps, 20% of intermediate polyps, 71% of large (>2.0 cm) polyps, and ...

Extent neuroendocrine differentiation can be encountered in many human neoplasm derived from different organs and systems using immunohistochemistry and ultrastructural techniques. The tumor cells' behaviors resemble those of neurons and neuroendocrine cells. The presence of neuroendocrine differentiation reputedly appears to be associated with a poorer prognosis than the adenocarcinoma counter...

Characteristic morphological and histochemical changes in mucosa adjacent to colorectal adenocarcinomas have been described. It has been suggested that this type of mucosa, labelled transitional mucosa (TM) because of its specific association with colorectal adenocarcinoma, is indicative of a premalignant change. In an investigation of mucosa adjacent to anal tumours extending into the rectum a...

Colorectal adenocarcinoma is positioned as the third of most common cancer which cases rise in Indonesia lately. More than 90% colorectal carcinoma are type. One prognostic factor invasion state tumor (T). Uncontrollable proliferation cell causes transformation paracellular permeability that increase claudin-4 expression (a protein located on main integral membrane). Claudin-4 activation influe...

A 56-year-old female with a background of metastatic rectal adenocarcinoma presented with a subglottic mass causing biphasic stridor. Transoral laser microsurgery and the use of fibrin glue prevented the need for tracheostomy. Six months postoperatively there was no evidence of recurrence. Laryngeal metastasis of colorectal adenocarcinoma, although remarkably rare, is perhaps more prevalent tha...

BACKGROUND Synchronous early primary cancers are rare and in addition synchronous adenocarcinoma of both rectum and gallbladder is extremely rare. CASE REPORT We report an unusual case of synchronous early primary adenocarcinoma of rectum and gallbladder. The patient was a 72-year-old woman with complaints of bloody stools and constipation. An endoscopy revealed adenocarcinoma of the lower re...
