چکیده
BACKGROUND Venous invasion by tumour is an independent prognostic indicator of both prognosis and risk of development of distant metastases in colorectal carcinoma. The use of special stains to aid its detection in pathology specimens is not currently universally recommended. AIMS To determine whether an elastica stain significantly increases the incidence of detection of vascular invasion compared with routinely stained sections. METHODS Serial sections from the 75 cases of colorectal carcinoma were stained by haematoxylin and eosin (H&E) only and elastica counterstained with H&E. The incidence of both intramural and extramural venous invasion was recorded and compared with that seen when the tumours were originally reported. RESULTS Extramural venous invasion had been noted in 14 of the pathology reports and was seen in 18 cases when only the H&E sections were viewed in the study. It was present in 32 cases when elastica stained sections were analysed. Intramural venous invasion was seen in eight cases on H&E sections and 30 cases on elastica stained sections. CONCLUSION The use of elastica stained serial sections to detect venous invasion in tumours should be recommended in guidelines for the reporting of colorectal carcinomas.

Accuracy of Elastic Tissue Stain in Detecting Venous Invasion in Colorectal Cancer
Objective: To determine the accuracy of Elastic tissue stains in detecting venous invasion in Colorectal cancer (CRC). Methods: Hematoxylin and Eosin (H&E) stained section from 100 cases of colorectal carcinoma were assessed for presence of venous invasion and compared with sections stained with Elastic Van Gieson (EVG) stain. Total number of cases showing evidence of venous invasion with H&E a...
متن کاملAltered expression of Lnc-OC1 and SIRT1 genes in colorectal cancer tissue
Backgrounds: SIRT1 plays an important role in many physiological processes, including metabolism, neuronal protection, senecence and inflammatory, by staging histones and multiple transcription factors. However, the complex mechanisms of SIRT1 signaling in tumors are not yet fully understood, as it acts as both an oncogen and a tumor suppressor. On the other hand, it has been shown that the Lnc...
متن کاملConclusions from a study of venous invasion in stage IV colorectal adenocarcinoma.
AIMS Venous invasion is an established predictor of prognosis in colorectal cancer (CRC). The reported incidence of venous invasion in CRC specimens varies between 10% and 89.5%, mainly as a result of interobserver variability and differences in specimen processing (for example, staining with haematoxylin and eosin (H+E) alone versus the addition of an elastic fibre stain). This study was perfo...

PURPOSE Venous invasion (VI) is widely accepted as a poor prognostic factor in colorectal cancer (CRC), and is indicated as a high-risk factor determining the use of adjuvant chemotherapy in CRC. However, there is marked interobserver and intraobserver variability in VI identification and marked variability in the real prevalence of VI in CRC. MATERIALS AND METHODS We investigated the detecti...
متن کاملInvestigating FGF11 gene transcription level in cancer cells among colorectal cancer patients
Background: Colorectal cancer (CRC) is the fourth leading cause of cancer-caused death around the world. Reports of the unnecessary transcription of family genes of the fibroblast growth factor in several types of cancer indicate the role of these factors in tumorgenesis and progression of cancer. Therefore, the level of FGF11 transcription was evaluated in colorectal cancer tumor tissues relat...
