Cerebral metastases of cutaneous melanoma

Abstract

Cerebral metastases of cutaneous melanoma carry a very poor prognosis. We report our experience of 31 patients who presented with cerebral metastasis of cutaneous melanoma in a 5-year period between mid-1991 and mid-1996. Cerebral metastases were diagnosed on computerized tomography (CT) scan after patients became symptomatic. The overall median survival in our series was 4 months. Seventeen patients (55%) received treatment with radiotherapy and dexamethasone with resolution of their symptoms, although median survival remained at 4 months. Six patients (19%) had surgery followed by whole brain radiotherapy, with median survival of 5 months. The remaining eight patients received dexamethasone alone. Data from patients surviving less than 2 months and over 6 months suggest that the poor prognostic factors are the presence of more than one cerebral metastasis and additional extracranial metastases.
