Colorectal cancers can be found anywhere from the cecum to the rectum. The cecum and ascending colon are involved in approxmiately 20% of cases. Colonic mass; pathology proven adenocarcinoma, with small regional lymphadenopathies Colorectal cancer (CRC) is the third most common cancer worldwide and represents 10% of all new cancer diagnoses (1). CRC is a heterogeneous disease that exhibits substantial spatial phenotypic and genotypic variations. Malignant CRC tumors are biologically complex, and our current understanding of how CRC behaves probably is limited At CT, colorectal cancer typically appears as a discrete soft-tissue mass that narrows the colonic lumen. Colorectal cancer can also manifest as focal colonic wall thickening and luminal narrowing. Complications of primary colonic malignancies such as obstruction, perforation, and fistula can be readily visualized with CT The apple core sign, also known as a napkin ring sign, is most frequently associated with constriction of the lumen of the colon by a stenosing annular colonic carcinoma due to bowel wall thickening with resultant circumferential constriction of the lumen

Radiology of colorectal cancer In the past 20 years, the radiology of colorectal cancer has evolved from the barium enema to advanced imaging modalities like phased array magnetic resonance imaging (MRI), virtual colonoscopy and positron emission tomography (PET). Nowadays, primary rectal cancers are preferably imaged with transr One of the challenges facing radiologists and clinicians is determining the cause of a diffusely dilated colon (≥ 6 cm) on abdominal radiographs. Pseudo-obstruction, dilatation of the colon without mechanical obstruction, can occur as a result of adynamic ileus, ACPO (also known as Ogilvie syndrome), or toxic megacolon

This is a basic article for medical students and other non-radiologists. Large bowel obstruction (LBO) occurs when there is mechanical obstruction of the large bowel and is often impressive on imaging on account of the ability of the large bowel to massively distend.This condition requires prompt diagnosis and treatment and metastatic colon cancer is 91%, 72%, and 13%.2 The scope of this guideline is to address the issues re-lated to the evaluation and treatment of patients who have been diagnosed with colon cancer. Matters pertinent to colon cancer screening and surveillance after colon cancer treatment,3 as well as rectal cancer,4 are addressed in sepa Colorectal cancer (CRC) is a rapid abnormal cell growth that affects the large intestines and/or rectum. These clusters of cells are called adenomatous polyps and develop from the tissue membrane of glandular tissue. Polyps can start as benign and non-cancerous but with time can develop and become cancerous bowel obstruction, it may not be sufficient to distinguish obstruction from other causes of colonic dilatation. Com-puted tomography is the imaging method of choice as it can establish the diagnosis and cause of large-bowel ob-struction. A contrast agent enema may be used to confirm or exclude large-bowel obstruction. In this review, the im advanced cancer. In a meta-analysis of radiographic studies,10 the DT ranged from 9.4 to 55.4 months for intramucosal cancer and 4.7 to 12.2 months for advanced cancer. Colorectal cancer grew rather slowly when the cancer was limited to the mucosa. However, when tumors grew down into the submucosa, growth speeds were accelerated.1

Inflammatory bowel disease and in particular ulcerative colitis is a predisposing factor for colorectal carcinoma. Dysplastic changes occur in adenomas in these patients and hence they warrant routine screening with colonoscopy. The dysplastic. An apparent dose-response relation was observed for those men with radiographic changes, similar to that seen in this CARET population for lung cancer , although colorectal cancer occurs only about half as often. Unlike our lung cancer results, no clear effect was evident on colon cancer risk for those without pleural changes or asbestosis on. The current standard of care for early-stage colorectal cancer consists of surgical resection followed by adjuvant chemotherapy (AC) in patients deemed to be at high risk of recurrence based on the presence of certain clinicopathologic features. 2,3 The goal of AC is to eradicate any post-surgery MRD that is undetectable by radiographic or. Appendix cancer is similar in some respects to colorectal cancer, particularly in that early-onset incidence is rising in both diseases (incidence rates of individuals of all ages with appendix cancer have risen 232% between 2000 and 2016 in the United States).

Most patients whose large bowel cancer has spread to other organs do not respond to immune therapy. We detected a rare gene mutation, termed 9p24.1 copy-number gain (CNG), in an otherwise incurable colorectal cancer that provoked an immune therapy response. We identified this gene mutation by gene-panel sequencing of DNA from a liver metastasis biopsy from a patient who had disease refractory. The correct answer is A. In the BECOME trial, 241 Chinese patients with colon cancer with liver metastases were randomized to mFOLFOX6 or mFOLFOX6 + bevacizumab.
