Don’t routinely order imaging studies for staging purposes on patients newly diagnosed with localized primary cutaneous melanoma unless there is suspicion for metastatic disease based on history and physical exam.
Routine imaging studies for localized melanoma including chest radiographs, brain MRI, cross-sectional imaging and PET/CT are insensitive at the lower limits of resolution and do not significantly improve staging of these patients. There is a low risk of metastases and also a risk of detecting findings unrelated to the melanoma (e.g., false positive findings or incidental, unrelated findings). Imaging should be performed if there are concerning findings on history and physical exam, and such tests should be driven by symptoms.
The Society of Surgical Oncology (SSO) maintains disease site workgroups (DSWGs) to represent the various disease sites associated with surgical oncology.
The DSWGs are comprised of experts in the following disease sites: gastrointestinal, melanoma/sarcoma, breast, hepatobiliary, endocrine/head & neck and colorectal. The SSO Quality Committee initiated the Choosing Wisely measure development process by asking the DSWGs to identify tests or procedures commonly used in their respective areas of expertise whose necessity should be questioned and discussed. The Quality Committee received submissions from all six disease sites; however, because the list was limited to five measures, the Committee felt it was precluded from incorporating measures representing all disease sites. As a means of refining the list of Choosing Wisely measures, the Quality Committee elected to include the five measures impacting the largest number of patients. The draft list was reduced significantly – eliminating the endocrine, hepatobiliary, and sarcoma measures. The five measures were selected from the breast, colorectal and melanoma sets. These five measures were submitted to and approved by the SSO Executive Council.
