A national retrospective study led by researchers at MD Anderson Cancer Center found no association between intensity of post-treatment surveillance and detection of recurrence or overall survival in patients with stage I, II or III colorectal cancer. Published in the Journal of the American Medical Association, the study is the largest of surveillance intensity in CRC ever conducted.
An analysis by researchers from the International Agency for Research on Cancer casts doubt on validity of an endpoint used in key studies of multi-cancer detection tests.
