Cerebral metastases of malignant melanoma: contemporary treatment modalities and survival outcome.

The aim of our study was to analyze prognostic factors, effect of treatment and survival outcome of a contemporary cohort of melanoma patients with cerebral metastases and eventually propose new recommendations regarding therapy. Sixty four patients with melanoma brain metastases were treated in our department within a 15-year period. We performed a retrospective analysis of their survival with respect to the type of treatment instituted. Four groups were formed according to treatment: Group A patients treated with surgery followed by radiotherapy; group B temozolomide as first-line treatment and radiotherapy after cerebral disease progression; group C radiotherapy alone; group D supportive care only. Patients* characteristics influenced the selection of treatment modality: Group A (7.8%) patients with a single brain metastasis (p=0.001) and controlled extra-cranial disease (p<0.0001), while Group D (21.8%) patients with ulcerated primary lesions (p=0.010) and uncontrolled extra-cranial disease (p<0.0001). Only group B (26.6%) and C (43.7%) patients with similar characteristics including more than one brain lesion. Median overall survival was 3 months. In univariate analysis, median survival for groups A, B, C and D was 12, 5, 3 and 2 months, respectively (p<0.0001). The survival difference between the surgery and non-surgery groups was statistically significant (p=0.0011). Patients treated with supportive care had the worse prognosis (p<0.0001). A survival benefit for patients receiving first-line treatment with temozolomide, as compared to those receiving radiotherapy alone was noted (p=0.0267). In multivariate survival analysis, the number of brain lesions (p=0.0138), the absence of uncontrolled extra-cranial disease (p=0.00221) and the type of treatment for the cerebral disease (p=0.0053) remained significant independent survival predictors. Patients' characteristics remain a critical factor for treatment selection. The number of brain metastases, the extent of disease and the type of treatment represent independent survival predictors. Melanoma patients with a single brain metastasis and controlled extra-cranial disease gain a survival benefit, if surgically treated. Including temozolomide in the first-line treatment of melanoma patients with brain metastases who would have been treated with radiotherapy alone, might present a promising future direction affecting the length of survival.

Malignant fibrous histiocytoma of the trunk metastatic to the liver: treatment with transcatheter intrahepatic chemoembolization.

We report a patient with symptomatic liver metastases as the sole site of recurrence of a previously resected malignant fibrous histiocytoma of the trunk. We treated the patient with two sessions of transcatheter chemoembolization. Tumor regression was achieved, and the patient remained free of symptoms 23 months after the diagnosis of liver involvement, when he died of acute myocardial infarction. To our knowledge, this is the only case of transcatheter chemoembolization of liver metastases from soft-tissue sarcoma reported in the literature. Although it is a single case, it shows that this method may be a promising therapy for this grave disease.
