Recent research indicates that more post-treatment screening does not impact colorectal cancer survival rates. A study published in JAMA and reported last week by Clinical Oncology News found no connection between post-treatment screening intensity and cancer recurrence detection when comparing 4,188 patients at 613 medical facilities with high-intensity screening to 4,341 patients at 539 medical facilities with low-intensity screening during the first three years of follow-up. Based on their data, the authors recommend following the guidelines of the UK’s National Institute for Health and Care Excellence, which calls for two CT scans in the first three years and biomarker testing every six months during the first three years post-treatment. The Clinical Oncology News piece quotes MSK’s Dr. Andrea Cercek, who states that unnecessary testing can lead to avoidable patient anxiety.
