Management of regional lymph nodes in patients with malignant melanoma: questionnaire survey of UK current practice.

In 2001, a short postal questionnaire regarding the management of regional lymph nodes in patients with cutaneous malignant melanoma was sent to 69 NHS departments of plastic and reconstructive surgery in the UK. Questionnaires were returned by 53 units, giving a response rate of 76.8%. Of these 53 units, 49 reported that they treat patients with primary malignant melanoma. There was considerable variation in the number of melanoma patients managed by each unit. This survey confirmed that elective lymph-node dissection is not routinely practiced in the UK; observation and therapeutic lymph-node dissection for patients who develop regional metastasis is the preferred pattern of care. The majority of centres in the UK do not use sentinel lymph node mapping: only 15 of the 49 units do so (30.6%). The number of sentinel lymph node biopsies performed in each unit varied significantly. There was considerable variation in the materials used and the process of care for sentinel lymph node biopsy. On the basis of this current practice, we recommend the setting up of a prospective clinical melanoma register to record the surgical treatment of melanoma patients.
