OBJECTIVE: To determine the effectiveness of follow-up tests for signaling recurrences in patients with intermediate- and high-risk malignant melanomas treated with curative intention. DESIGN: Retrospective analysis of prospectively collected data. SETTING: North Central Cancer Treatment Group. PATIENTS: A total of 261 patients with resected local (> or = 1.69 mm) and regional nodal malignant melanomas who were enrolled in a single prospective adjuvant trial were studied. All patients were scheduled to be followed up monthly for 2 months, then every 2 months for the first year, every 4 months the second year, every 6 months the next 3 years, and annually thereafter, with each visit consisting of a history, physical examination, complete blood cell count, blood chemistry panel, and a chest x-ray. RESULTS: Of the 145 evaluable patients who developed recurrent melanomas, 99 patients (68%) developed symptoms that signaled the diagnosis of recurrent disease. Physical examination of asymptomatic patients led to the diagnosis of recurrent disease in 37 patients (26%). The other nine patients (6%) with recurrent disease had abnormal chest x-rays. Laboratory results were never a sole indicator of recurrent disease. CONCLUSION: The majority of recurrences following resection of primary melanomas are discovered by history and/or physical examination despite the frequent use of other follow-up tests. The present data indicate that routine blood analyses and chest x-rays have limited value in the postoperative follow-up of patients with resected intermediate- and high-risk melanomas.
