ABSTRACT
BACKGROUND: Epidemiological studies concerning melanoma are most often performed by general practitioners and dermatologists in patients previously aware of the risk of nevi. OBJECTIVE: To determine the efficiency of early detection of melanoma by occupational medicine specialists trained in the use of ABCDE criteria during annual systematic examination of workers. METHODS: A total of 370 subjects with suspect lesions that demonstrated at least 2 of 5 ABCDE criteria were selected from 65000 employees examined; these subjects were requested to see their physician about possible excision. Of the 370 subjects, 273 (73.8%) were seen at a second-year follow-up visit to determine their outcome. RESULTS: Among the 273 subjects who were seen again, 172 (63.0%) had consulted a physician. For the 101 subjects who had not seen a physician, the main reason was the negligence (86.1%). A total of 353 atypical nevi were observed. The mean number of ABCDE criteria noted per lesion was 2.6. Lesion diameter greater than 6 mm was the most frequent (80.5%) and enlargement the least frequent criteria seen; heterochromous coloration and diameter greater than 6 mm was the most common association (54.5%). Five histologically confirmed melanomas were found among nevi excised in 78 subjects. CONCLUSION: This screening approach seems efficient for the early detection of melanoma, demonstrating an incidence of 7.7 per 100000 vs. 9 per 100000 in the general French population.
