Background
There are no evidence-based guidelines for surveillance of patients with melanoma following surgical treatment. We performed a systematic review to identify current stage-specific surveillance practices for patients with melanoma by country and physician specialty.
Methods
Three major medical indices, MEDLINE, the Cochrane Library database, and Scopus, were reviewed to identify articles published in January 1970 to October 2011 that included detailed information about surveillance of patients with melanoma after initial surgical treatment. Data on surveillance intervals and recommended evaluation were extracted and categorized by country and, when reported, physician specialty.
Results
One hundred four articles from 10 countries and 4 physician specialties (dermatology, surgical oncology, medical oncology, and general practice) met the inclusion criteria, including 43 providing specific patient-level data. The articles showed wide variation with respect to surveillance intervals and recommended evaluations. Variation was greatest for patients with stage I disease, for whom follow-up frequency ranged from 1 to 6 visits per year during years 1 and 2 after treatment. All 4 physician specialties agreed that for years 1–3, the follow-up frequency should be 4 times per year for all patients. For years 4 and 5, surgical oncologists recommended 2 follow-up visits per year, whereas general practitioners, dermatologists, and medical oncologists recommended 4 visits per year. Recommended imaging and laboratory evaluations were most intense in the United Kingdom and most minimalist in The Netherlands. While general practitioners did not recommend routine laboratory or imaging tests for surveillance, all other specialties utilized both in their surveillance practice. Self skin-examination was recommended for surveillance in all countries and by all practitioner specialties.
Conclusions
There is significant intercountry and interspecialty variation in surveillance of patients with melanoma. As the number of melanoma survivors increases, it will be critical to examine the benefits and costs of various follow-up strategies to establish consensus guidelines for melanoma post-treatment surveillance.
