Medical history, physical examination, and carcinoembryonic antigen testing should be performed every 3 to 6 months for 5 years. Patients at higher risk of recurrence should be considered for testing in the more frequent end of the range. A computed tomography scan (abdominal and chest) is recommended annually for 3 years, in most cases. Positron emission tomography scans should not be used for surveillance outside of a clinical trial. A surveillance colonoscopy should be performed 1 year after the initial surgery and then every 5 years, dictated by the findings of the previous one. If a colonoscopy was not preformed before diagnosis, it should be done after completion of adjuvant therapy (before 1 year). Secondary prevention (maintaining a healthy body weight and active lifestyle) is recommended. If a patient is not a candidate for surgery or systemic therapy because of severe comorbid conditions, surveillance tests should not be performed. A treatment plan from the specialist should have clear directions on appropriate follow-up by a nonspecialist.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1200\/jco.2013.50.7442","type":"journal-article","created":{"date-parts":[[2013,11,12]],"date-time":"2013-11-12T23:31:39Z","timestamp":1384299099000},"page":"4465-4470","source":"Crossref","is-referenced-by-count":313,"title":["Follow-Up Care, Surveillance Protocol, and Secondary Prevention Measures for Survivors of Colorectal Cancer: American Society of Clinical Oncology Clinical Practice Guideline Endorsement"],"prefix":"10.1200","volume":"31","author":[{"given":"Jeffrey A.","family":"Meyerhardt","sequence":"first","affiliation":[{"name":"Jeffrey A.
