We sought to determine if treatment in a regional cancer center (RCC) impacts guideline adherence and outcomes for patients with melanoma.</p> </sec> <sec id="jso23981-sec-0002" sec-type="section"> <title>Methods</title> <p>In Alberta, Canada, 561 patients with stage I–IIIC primary melanoma were diagnosed between January 2009 and December 2010. The electronic health record was used to capture demographic and pathologic data. Provincial guidelines for sentinel lymph node biopsy (SLNB) and wide local excision (WLE) are based on recommendations of several pre‐existing guidelines including the National Comprehensive Cancer Network.</p> </sec> <sec id="jso23981-sec-0003" sec-type="section"> <title>Results</title> <p>148 of 561 patients were identified as having been treated at a RCC. Median follow‐up was 45 months. Patients treated at the RCC presented with higher stage melanomas. The RCC was more likely to follow guideline recommendations for performing SLNB (81.3% vs. 55.4%, <italic>P </italic>< 0.0001) but not for the extent of WLE (76.6% vs. 84.1%, <italic>P </italic>= 0.054). Overall survival was impacted by tumor thickness (HR 1.14, <italic>P </italic>< 0.0001), ulceration (HR 5.58, <italic>P </italic>< 0.0001), and mitoses (HR 0.59, <italic>P </italic>= 0.05).</p> </sec> <sec id="jso23981-sec-0004" sec-type="section"> <title>Conclusions</title> <p>The RCC more closely followed guidelines for SLNB but not for WLE. Despite patients treated at the RCC presenting with a more advanced stage, overall survival and disease‐free survival appear to not be affected by treatment center. <italic>J. Surg.
