Updated Swiss guidelines for the treatment and follow-up of cutaneous melanoma.

Melanoma is the most common lethal cutaneous neoplasm. In order to harmonize treatment and follow-up of melanoma patients, guidelines for the management of melanoma in Switzerland have been inaugurated in 2001. These have been approved by all Swiss medical societies involved in the care of melanoma patients. New data necessitated changes concerning the safety margins (reduction to maximally 2 cm) and modifications of the recommendations of follow-up.
