TLDR
It is recommended that carcinoembryonic antigen (CEA) be ordered preoperatively, if it would assist in staging and surgical planning, and data are insufficient to recommend the routine use of p53, ras, thymidine synthase, dihydropyrimidine dehydrogenase,Thymidine phosphorylase, microsatellite instability, 18q loss of heterozygosity, or deleted in colon cancer (DCC) protein in the management of patients with col
Abstract
Purpose To update the recommendations for the use of tumor marker tests in the prevention, screening, treatment, and surveillance of gastrointestinal cancers. Methods For the 2006 update, an update committee composed of members from the full Panel was formed to complete the review and analysis of data published since 1999. Computerized literature searches of Medline and the Cochrane Collaboration Library were performed. The Update Committee’s literature review focused attention on available systematic reviews and meta-analyses of published tumor marker studies.

Glycosylation in cancer: mechanisms and clinical implications

TL;DR: The roles of glycans are highlighted by the fact that alterations in glycosylation regulate the development and progression of cancer, serving as important biomarkers and providing a set of specific targets for therapeutic intervention.

Wild-Type BRAF Is Required for Response to Panitumumab or Cetuximab in Metastatic Colorectal Cancer

TL;DR: BRAF wild-type is required for response to panitumumab or cetuximab and could be used to select patients who are eligible for the treatment and should be used for selection.

International validation of the consensus Immunoscore for the classification of colon cancer: a prognostic and accuracy study

Franck Pagès, +120 more
- 26 May 2018 - 
TL;DR: The immunoscore provides a reliable estimate of the risk of recurrence in patients with colon cancer and supports the implementation of the consensus Immunoscore as a new component of a TNM-Immune classification of cancer.

Towards the introduction of the 'Immunoscore' in the classification of malignant tumours.

Jérôme Galon, +56 more
TL;DR: In colorectal cancer, the Immunoscore may add to the significance of the current AJCC/UICC TNM classification, since it has been demonstrated to be a prognostic factor superior to the AJCC or UICCTNM classification.

Genetic alterations during colorectal-tumor development.

TL;DR: It is found that ras-gene mutations occurred in 58 percent of adenomas larger than 1 cm and in 47 percent of carcinomas, which are consistent with a model of colorectal tumorigenesis in which the steps required for the development of cancer often involve the mutational activation of an oncogene coupled with the loss of several genes that normally suppress tumors.

Clinical Score for Predicting Recurrence After Hepatic Resection for Metastatic Colorectal Cancer: Analysis of 1001 Consecutive Cases

TL;DR: There is a need for clearly defined and widely applicable clinical criteria for the selection of patients who may benefit from hepatic resection for metastatic colorectal cancer and studies of preoperative staging techniques or of adjuvant therapies should consider using such a score for stratification of patients.

Microsatellite instability in cancer of the proximal colon

TL;DR: Colorectal tumor DNA was examined for somatic instability at (CA)n repeats on human chromosomes 5q, 15q, 17p, and 18q, and this instability was significantly correlated with the tumor's location in the proximal colon and with increased patient survival and loss of heterozygosity.
