Feasibility Study to Investigate Rectal Mucus in Aero-Digestive Tract Cancer.

Summary

The aim of the study is to assess the feasibility of genomic and epigenetic analysis of rectal mucus to detect non-colorectal cancers of the aero- digestive tract using samples collected by the OriCol™ Sampling Device. The primary objective of the study is to assess whether significant changes in DNA mutation and methylation associated with Non-colorectal cancers of the Aero-digestive Tract (NCRCADT) can be detected in rectal mucus as shed cells and cell-free DNA (cfDNA) pass through the gut and theoretically can be collected from rectal mucus. Secondary objectives will assess the participant acceptability of the OriCol™ Sampling Device for Pancreatic Ductal Adenocarcinoma, Non-Small Cell Cancer of the Lung, Colorectal Cancer and Urological Cancer controls as well as contributing to a genomic library collating information about rectal mucus.
