In a 57-year-old male patient meningitic symptoms occurred.
CSF
cytology exhibited carcinoma cells, thus establishing the diagnosis of carcinomatous meningeosis. The primary site of the tumor or
metastases
were not detected intra vitam. The autopsy revealed a malignant thymoma with an exclusive metastatic participation of the leptomeninges except for some few regional lymph nodes. Cerebral metastases of malignant thymoma is an extremely rare condition.

Over a period of 13 years, 353 cases of
metastases
in the brain, spinal canal or peripheral nerves were treated in 14,350 inpatients. In 79.6% of the cases, the
metastases
were localized intracranially, in 14.7% spinally, in 2.6% peripherally and in 3.1% in several of these sites. Solitary tumors predominated (65.7%). Of 420 intracranial
metastases
, 336 were located supratentorially (80%) with a slight preponderance on the left side (54.5%), 15% cerebellar, and 5% in the brainstem. Of the spinal
metastases
, 80% were located in the thoracic spinal cord. Almost 60% of the cases also displayed
metastases
outside the nervous system, mainly in the skeletal system and the lungs. The most frequent primary tumor was bronchial carcinoma (26,6%) followed by breast cancer (19.5%) and unknown primary tumor (17.6%), which was also not found on autopsy in 0.8%. Rare primary tumors were parotid and pancreatic carcinomas, testicular and bladder tumors. There are correlations between the primary tumor and the location of the
metastases
in the nervous system in general and in the brain in particular. The latency between diagnosis of the primary tumor and that of the metastasis was 1-3 years. In one out of three cases, the metastasis in the nervous system was the first sign of the tumor condition. In six cases, the metastasis was removed before the primary tumor and two possible kinds of primary tumors were found in seven cases. Compared to intracranial hypertension focal deficit manifestations including focal convulsions occurred twice as frequently in cerebral
metastases
. Spinal metastases led to

The concurrent administration of Metrazol (60 mg/kg, i.v.) to anaesthetized rats enhances the cerebral penetration of the anticancer agent razoxane. Such an enhancement leads to an increase in the therapeutic efficacy of razoxane against intracerebrally sequestered L1210 leukaemia cells in mice. The combination of Metrazol and melphalan was also examined to see if the concentration of other anticancer agents in
CSF
could be enhanced.

Between 1957 and February 1981, 782 patients received cytotoxic chemotherapy for gestational trophoblastic tumors (GTT) in the Department of Medical Oncology, Charing Cross Hospital (London, England). Sixty-nine (8.8%) patients had central nervous system (CNS)
metastases
. Thirty-three of them (48%) presented with CNS disease prior to treatment (CNS presentation group), and 36 (52%) developed CNS disease while on treatment, or relapsed in the CNS after an initial complete or partial remission (late CNS group). Treatment included systemic and intrathecal chemotherapy, and, in several cases neurosurgery, whole brain irradiation, and immunotherapy. Life-table analysis projects an overall survival of 49% for the CNS presentation group and 6% for the late CNS group. Prognosis has improved with time; prior to 1974, 38% of the CNS presentation group and none of the late CNS group survived. After 1974 overall survival has been 80% in the CNS presentation group and 25% in the late CNS group. The principal elements in the successful management of such cases are: (1) CNS prophylaxis with intrathecal methotrexate for patients at risk of developing brain metastases; (2) early detection of CNS lesions by prompt recognition of their clinical features, measurement of the ratio of
CSF
to serum human chorionic gonadotropin concentration, and appropriate use of computerized tomography of the brain; and (3) a combination of systemic and intrathecal therapy for patients developing brain secondaries.

The authors report 5 cases of intramedullary
metastases
, observed in the last 5 years. In 2 cases, the way of spreading was via the
CSF
, in 2 cases via the systemic circulation, and in 1 case along the perineural sheaths. A comparison with similar studies in the literature is followed by a brief discussion on treatment and prognosis.

Clinicopathologic findings are reported in the case of an unusual combined degeneration of the cerebellum and spinal cord associated with bronchial carcinoma. Clinical features were sudden sensory onset, rapid and complete flaccid paraplegia with ascending course, sphincter paralysis, rapid impairment of general condition, and high protein content in
CSF
without inflammatory cell reaction. The neuropathologic findings included massive transverse necrosis at the thoracic level and degeneration of the ascending and descending tracts. The necrotic areas involved mostly white matter without any vascular topography. There was no inflammation or specific vascular alteration. In the cerebellum widespread cortical atrophy was observed. There were no
metastases
in the cord, meninges, vertebral column, or nerve roots. The simultaneous occurrence of two distinct types of nervous tissue alterations reflects the pathomechanisms effective in CNS reactions to extraneuronal malignancy.

Three clinico-pathological cases of necrotic myelopathies with a distant malignancy are presented. Two cases had a lymphosarcoma and one case a prostatic carcinoma. They were compared to 13 well studied other cases collected in the literature. These myelopathies were related to solid visceral tumours in 8 cases and to lymphomas in 5 cases. The disease could be individualized on clinical grounds (flaccid paraplegia with bladder and bowell incontinence and sensory loss without clear-cut upper boundary developing over a few weeks with normal
CSF
and fast impairement of general condition), and, on pathological features. It is characterized by one or several spinal cord necrosis areas, often asymetrical, involving mostly white matter, without any vascular topography. Axons are involved as well as myelin sheats. There is mild inflammation and no specific vascular alteration. There is no
metastases
in the cord, meninges, vertebral column or nerve root. No vascular occlusion is found. The mechanism of the disease is unknown. The frequent occurence of lymphomas could suggest the presence of immunopathological factors.

Forty-seven children with histologically confirmed medulloblastoma are considered. Forty-five cases were surgically by direct approach to the tumour, while two cases were treated only with a shunt. A shunt was inserted preoperatively in 14 cases, postoperatively in 4 cases. Surgical resection was total or subtotal in 52% of cases, partial in 35%, and limited to a biopsy in 13%. Radiation treatment to the entire neuraxis was done in 37 cases: 10 of these cases received additional chemotherapy--mostly with CCNU--as primary treatment for medulloblastoma. Ten patients died within 30 days after surgery. Twenty-two patients died months after treatment, mainly from tumour recurrence (19 cases). One patient was lost to follow-up. Thirteen patients are survivors from 10 months to 20 years after treatment. As a whole, the one year survival rate has been 67%, 3 year survival 43%, and 5 year survival 27%. Complications affecting prognosis have been presented by tumour recurrence and
metastases
.
CSF
shunting and lack of prophylactic irradiation to the cerebral hemispheres have been considered responsible for the high incidence of supratentorial
metastases
in our series. Factors influencing prognosis have been the extent of tumour resection and association of primary chemotherapy with radiotherapy. Within 3 years after surgery survival has been 52% in cases with total resection against 31% in cases with partial resection of tumour. As regards chemotherapy, 3 year survival has been 60% for patients with combined treatment (chemo- and radiotherapy) against 37% in patients with radiotherapy alone. It is concluded that the best results in children with medulloblastoma are achieved by a radical resection, associated with a combined primary treatment of radiotherapy and chemotherapy.

The combination of mitozantrone, methotrexate and mitomycin (3M) gives a response rate of around 50% in patients with advanced breast cancer. The predominant toxicity is haematological. In this study, previously untreated patients were given 3M with increasing doses of mitozantrone (7-14 mg m-2) with recombinant human granulocyte colony-stimulating factor (metHuG-
CSF
) (filgrastim) to prevent marrow toxicity. Doses administered were 7 mg m-2 mitomycin i.v. 6 weekly, methotrexate i.v. 35 mg m-2 (maximum 50 mg) 3 weekly and mitozantrone i.v. 3 weekly as follows: 7 mg m-2, six patients (group 1); 10 mg m-2, six patients (group 2); 12 mg m-2, six patients (group 3); 14 mg m-2, six patients (group 4); all on day 1 for six cycles at the assigned dose. All patients received filgrastim (Amgen 0.3 mg ml-1) at a dose of 5 micrograms kg-1 subcutaneously daily on days 4-17 of each cycle. All treatment was given on an out-patient basis. A total of 24 patients were entered into the study. The median age was 63 years (range 48-75). ECOG performance status was 0 in ten, 1 in 11 patients and 2 in three patients. Locoregional disease alone was present in seven patients. The remainder had one or more sites of
metastases
. The actual dose administered to the 24 patients was as follows. The six patients in group 1 all completed six courses of treatment as per protocol. In group 2, three patients completed six courses, two stopped because of toxicity after one and four courses and one had progressive disease after one course. In group 3, three patients completed and three stopped early because of progressive disease. In group 4, two patients completed, one progressed after four courses and three responding patients stopped treatment because of toxicity. The maximum tolerated dose of mitozantrone in the 3M combination was 12 mg m-2. The use of filgrastim with increasing doses of chemotherapy prevents neutropenia, but other toxicities, namely thrombocytopenia and lethargy, then become dose limiting.
