title: [Extramedullary localization of acute leukemia. I. The involvement of the central nervous system].
abstract: The involvement of the central nervous system in acute leukemia was studied in 15 adult patient. 60% of the patients were up to 35 years of age and 12 of them (80%) were with acute lymphoblastic leukemia. In 12 of the patients the nervous system was affected in the acute course of the disease, in one female patients--in the course of induction treatment and in the remaining patients--after the induction treatment. The manifestations of neuroleukemia are predominantly meningoradicular irritation with headache--in 86.7% of the patients, diplopia, papilledema, dysarthria and palpebral ptosis with affection of the cranial nerves (III, IV, V, VI, VII, VIII, IX, XII). In 12 patients (87.5%) blast cells were found in the cerebrospinal fluid in numbers ranging from 70 up to 36,000/mm3. In 26.7% of the patients other extramedullary localizations of leukemia were found parallelly (testes, thyroid gland hypopharynx, muscles). The application of methotrexate intrathecally and radiation therapy of the cranium led to a remission in 43% of the patients. Favourable results with considerably prolonged survival can be achieved also in patients with many recurrences of the disease. The need of neuroleukemia prophylaxis is proved (it is obligatory for the patients with acute lymphatic leukemia and with some forms of acute myeloblastic leukemia).
