Cohort A consisted of 1208 patients, out of whom 78 (6%) were diagnosed with local recurrence. Forty-six patients were diagnosed between scheduled follow-up visits. Fifty-eight patients were symptomat... A majority of patients with local recurrence were diagnosed outside of the scheduled follow-up. Most of the patients were symptomatic at diagnosis. Symptoms were common in patients after rectal cancer...
