The role of ultrasound in detection and management of regional disease in melanoma patients☆

Abstract 

Melanoma follow-up programs are directed towards early detection of tumor recurrence. Because the majority of first relapses occur in the regional lymph node area, special focus is placed on this region using various techniques in addition to physical examination. During the last several years, particularly ultrasound B-scan has evolved as a technique of major importance for detection of such regional melanoma recurrences. The technique shows high sensitivity and specificity, discriminating regional or subcutaneous melanoma metastases from nonspecific nodes. Furthermore, suspicious findings can be evaluated quickly and reliably by the minimally invasive technique of ultrasound-guided fine-needle aspiration cytology (FNAC). For regional metastases located deeply or close to vulnerable structures, the new method of ultrasound-guided anchor-wire–marking facilitates subsequent surgery. In summary, ultrasound B-scan has become an essential technique in the follow-up of melanoma patients. Semin Oncol 29:353-360. Copyright 2002, Elsevier Science (USA). All rights reserved.
