a This includes patients with pathological downstaging after neoadjuvant chemoradiation (n = 69); a complete remission of histologically proven colorectal cancer was staged as stage 0.
b Staging of the lung in this cohort was done with chest CT (n = 415) or chest X-ray (n = 197).
c Other localisations were brain and skeletal metastases.
d Of 23 patients, 20 patients had no surgery and 3 patients had no resection resulting in an unknown TN status. Of 23 patients, 11 patients had an unknown M status and 12 patients had M0 status.
