Brain metastases occur in 20-40% of patients with cancer and their frequency has increased over time. Lung, breast and skin (melanoma) are the commonest sources of brain metastases, and in up to 15% of patients the primary site remains unknown. After the introduction of MRI, multiple lesions have outnumbered single lesions. ⋯ A small subgroup of these latter may benefit from surgery. The response rate of brain metastases to chemotherapy is similar to the response rate of the primary tumor and extracranial metastases, some tumor types being more chemosensitive (small cell lung carcinoma, breast carcinoma, germ cell tumors). New radiosensitizers and cytotoxic or cytostatic agents, and innovative technique of drug delivery are being investigated.

Clinical TrialLow molecular weight heparin for deep vein thrombosis in glioma patients.
The treatment and secondary prophylaxis of deep vein thrombosis (DVT) and pulmonary embolism, a common complication in patients with malignant glioma, has remained controversial. We treated 11 patients with malignant glioma and DVT prospectively with low molecular weight heparin (LMWH) at 175 IU/kg for 10 days and then for 3 months at 100 IU/kg. No patient developed bleeding complications or any other severe side effects of LMWH treatment. ⋯ After increasing the dose to 175 IU/kg he had no further recurrence. One patient had recurrence of DVT after a fracture of the leg affected by DVT at 8 months after the diagnosis of DVT and 5 months after the end of LMWH therapy. LMWH therapy may be safe and effective in the treatment and secondary prophylaxis of DVT in patients with malignant glioma.
