PRODEFENSIN-A6 ASSAY METHOD FOR THE IN VITRO DIAGNOSIS OF COLORECTAL CANCER

摘要

The present invention relates to a method for the in vitro diagnosis of colorectal cancer by determining the presence of the Prodefensin-A6 tumour marker in a biological sample taken from a patient suspected of having colorectal cancer, it being possible for said method to be used both in early diagnosis, screening, therapeutic follow-up and prognosis, and in relapse diagnosis in relation to colorectal cancer.
