[Brain metastases as an initial manifestation of tumor disease].
A retrospective study compared a group of 122 patients with brain metastases from unknown primaries with a second group of 121 patients, who developed brain metastases in the course of a known malignant disease. Special attention was paid to the kind of primary cancer, therapeutic influences and prognostic differences. The results pointed to a late occurrence of brain metastases in breast cancer, no patient with this type of cancer being found in group 1. Melanoma and colorectal cancer were also found predominantly in group 2, whereas lung cancer was the most common cause of metastasis in group 1 and the most frequent cancer in both groups. Clinical course, therapy and outcome showed no significant differences between the two groups. Mean survival time was 4.6 (+/- 6) months for the patient series as a whole. Patients with breast cancer had a significantly higher survival rate than those with other forms of cancer. Localisation and degree of malignancy mainly determine the life-prognosis, the type and intensity of therapy being of secondary importance.
