Resection of metastatic melanoma following wire localization guided by computed tomography or ultrasound.
Melanoma is an aggressive tumour with the propensity to metastasize through the lymphatic system and blood. Patients at high risk for developing metastatic disease are evaluated clinically together with chest X-rays and when indicated computed tomography (CT) scans. Wire localization is routinely used in non-palpable breast cancer to facilitate surgical resection. This study demonstrates the applicability of wire localization and surgical resection of non-palpable, deep subcutaneous or Intramuscular metastatic melanoma detected by CT or ultrasound. The medical records of six patients with malignant melanoma were retrospectively reviewed. Each patient with malignant melanoma developed metastatic involvement detected by CT scan or ultrasound at the UCSF/Mount Zion Medical Center, California, USA. A Copanz needle was inserted into the tumours under local anaesthesia. The patients were transported to the operating room and underwent wire-guided surgical resection of the tumour under general anaesthesia or intravenous sedation. In all six patients the tumour was successfully resected following CT- or ultrasound-guided wire localization of the metastatic foci. In conclusion, nonpalpable metastatic melanoma may be resected using CT-or ultrasound-guided wire localization. This technique offers several advantages, Including minimal surgical dissection, shorter operative times and decreased postoperative morbidity.
