Genomic and Transcriptomic Profile of Paired Primary-Metastasis Colorectal Tumors

The goal of this study is to identify mechanisms of metastization in a portuguese cohort of colorectal cancer. Namely, we want to identify patterns of genomic and transcriptomic diversification associated with metastasis.

Dataset ID	Description	Technology	Samples
EGAD00001007686	Samples encompass primary colorectal tumors, adjacent normal colonic mucosa and metastasis of 12 patients, collected by Medical Pathologists from surgically removed specimens. Normal mucosa samples were taken more than 2 cm away from the tumor. Tissues were embedded in optimal cutting temperature (OCT) medium, snapshot frozen in liquid nitrogen within 40 minutes of collection and preserved at -80ºC. Samples were collected between June 2010 and October 2017 as part of a prospective biobanking project.	Illumina NovaSeq 6000	36
EGAD00001009506	Samples encompass primary colorectal tumors or metastasis of 75 patients, collected by Medical Pathologists from surgically removed specimens. Tissues were embedded in optimal cutting temperature (OCT) medium, snapshot frozen in liquid nitrogen within 40 minutes of collection and preserved at -80ºC. Samples were collected between June 2010 and October 2017 as part of a prospective biobanking project.	Illumina NovaSeq 6000	75
