This week's artwork was donated by Lonny, a pediatric cancer patient who received treatment at The Children's Hospital of Philadelphia . Smith TJ, et al. Recommended colorectal cancer surveillance guidelines by the American Society of Clinical Oncology.
Tests are to be recommended only if they have an impact on the outcomes listed below.
All tests described in the literature for postoperative monitoring were considered. In addition, the data were critically evaluated to determine the optimal frequency of monitoring. Colorectal Cancer Surveillance Expert Panel was guided by the principle of cost minimization, ie, when two strategies were believed to be equally effective, the least expensive test was recommended. Keywords included colorectal cancer, follow-up, and carcinoembryonic antigen, as well as the names of the specific tests. The search was broadened by articles from the tumor marker ASCO panel literature search, as well as from bibliographies of selected articles.
