Diagnosis and treatment of early melanoma. NIH Consensus Development Conference. January 27-29, 1992.

The National Institutes of Health Consensus Development Conference on Diagnosis and Treatment of Early Melanoma brought together experts in dermatology, pathology, epidemiology, public education, surveillance techniques, and potential new technologies as well as other health care professionals and the public to address (1) the clinical and histological characteristics of early melanoma; (2) the appropriate diagnosis, management, and followup of patients with early melanoma; (3) the role of dysplastic nevi and their significance; and (4) the role of education and screening in preventing melanoma morbidity and mortality. Following 2 days of presentations by experts and discussion by the audience, a consensus panel weighted the scientific evidence and prepared their consensus statement. Among their findings, the panel recommended that (1) melanoma in situ is a distinct entity effectively treated surgically with 0.5 centimeter margins; (2) thin invasive melanoma, less than 1 millimeter thick has the potential for long-term survival in more than 90 percent of patients after surgical excision with a 1 centimeter margin; (3) elective lymph node dissections and extensive staging evaluations are not recommended in early melanoma; (4) patients with early melanoma are at low risk for relapse but may be at high risk for development of subsequent melanomas and should be followed closely; (5) some family members of patients with melanoma are at increased risk for melanoma and should be enrolled in surveillance programs; and (6) education and screening programs have the potential to decrease morbidity and mortality from melanoma.
