Mucinous colorectal tumors

Signet ring cell carcinoma (SRCC) represents an extremely rare histological type for colon cancer, accounting for less than 1% of all colon neoplasms. SRCC is usually aggressive and it is associated with poor prognosis. It can be divided into mucinous adenocarcinoma (MAC) with signet cells and signet cell of more than 50% of the tumor area. Main differential diagnosis is metastatic gastric signet cell carcinoma.

The Tn neoantigen (GalNAcα1-O-Ser/Thr) is an O-glycan expressed in various types of human cancers. Studies in several Tn-expressing cancer cell lines and pancreatic tumors have identified loss of Cosmc expression caused by either mutations or promoter hypermethylation. In this study, we explored the mechanism(s) for Tn expression in human colorectal cancers (CRC).

Broad copy number aberrations (BCNAs) represent a common form of genome instability in colorectal cancer (CRC). CRCs show large variations in their level of aneuploidy: microsatellite-instable (MSI) tumors are known to have a near-diploid karyotype while microsatellite-stable (MSS) tumors show high level of chromosomal instability.
