RESUMEN
We collected 6 case-reports of symptomatric non removable low grade fibrillary astrocytoma of adults treated with a procarbazine-CCNU-vincristine chemotherapy regimen. All patients had drug-resistant epilepsy but brain imaging was stable. Total gross resection was rejected because of Volume or tumor location. After 4 to 7 cycles of chemotherapy, 2 patients had partial response and one minor response on brain MRI. All of them were seizure-free. Progression free survival was not reached at 5 Years. Up-front chemotherapy for low-grade astrocytomas may be useful and has to be prospectively evaluated.

Systemic metastases from ovarian carcinoma are frequent, but they seldom affect the central nervous system. We present here the case of a patient treated for an ovarian cancer by surgery and chemotherapy. Three months after the end of chemotherapy, the patient developed cerebral metastases from ovarian carcinoma (CMOC) treated by iterative surgery and and whole brain irradiation. As the frequency of solitary cerebral metastasis of ovarian cancer is higher than with other cancers, it is likely that they behave slightly differently. Literature analysis reveals an increase in the incidence of CMOC since the middle of the nineties. CMOC can occur during or after adjuvant chemotherapy and the best management strategies to better define determinants of survival for patients are not well known. It appears that a better outcome of CMOC may be obtained by an aggressive treatment, if possible, including surgery, radiotherapy, and chemotherapy. Taking into account the increase in the incidence of the CMOC and their early occurrence, some authors have proposed a prophylactic brain radiotherapy in patients who receive adjuvant chemotherapy.

PURPOSE: We reviewed a series of 14 cases of filum terminale ependymoma and 264 cases in the literature, to study the characteristics of these tumors and specifically to determine factors influencing recurrence. MATERIAL AND METHODS: This series analyzed data between 1984 and 1998. The mean follow-up period was 5.5 years and the median age 40 years. Pain was the first symptom, except in one case, with progressive sensitive-motor deficit. Four patients had a myelography and a CT scan, and ten a MRI. All patients were operated with a total resection in 12 cases. All tumors, except one, were a myxopapillary ependymoma. RESULTS: Clinical results were excellent in 2 cases, good in 8, stable in 2 and worse in 2. Two patients had a recurrence after an initial sub-total resection, both were operated on again, followed by post-operative radiotherapy. Among the 278 filum terminale ependymoma, removal was total in 200 (72%). A recurrence occurred in 15% of them after total removal, and in 43% after partial removal (p<0.001). Among patients with partial removal, recurrence was observed in 33% of them if they had post-operative radiotherapy, and in 55% of them if they did not have post-operative radiotherapy (p<0.05). CONCLUSION: The extent of tumor removal has a statistically significant effect upon recurrence. This review is in favor of post-operative radiotherapy in case of partial removal, but this systematic attitude can be discussed after a critical analysis of this study. Long term follow-up is mandatory due to the possibility of late recurrence.
