Cerebral granular cell tumors: report of a case and a note on their nature and expected behavior.

A case of cerebral granular cell tumor (GCT) is reported. Histologically, the growth was composed of benign astrocytes, granular cells and transitional forms between both elements. Glial fibrillary acidic protein was detected in the glial component and, to a lesser extent, in the granular cells. Alpha-1-antichymotrypsin was demonstrated in the latter component only. Ultrastructural study also supported the evidence that neoplastic astrocytes became granular cells. The survey of the literature and our own results suggest that GCTs in this particular location, even when histologically benign, seem to have a worse prognosis than the low-grade supratentorial astrocytomas.

[Conservative treatment of breast cancer. Experience of the Consultation Group of Breast Oncology of the Santa Maria Hospital].

Since 1983, the Oncology Breast Group Consultation of the H.S.M. has been practicing a Conservative Treatment in women with early stage breast carcinoma. So far, 61 women stages I and II, were submitted to Conservative Treatment, which consists of limited Surgery, followed by Radiotherapy. 20 patients had performed associated systemic therapy, because they presented axillary positive lymphnodes. 10 of there were pre-menopause and they had performed Chemotherapy and the other 10 were post-menopause receiving Hormonotherapy. Of the 61 patients that constitute this series, two had local failure; two had hepatic metastasis and another two had secondary neoplasms. The remaining 55 are in good condition. In 54 patients with follow-up superior to 3 month oesthetical evaluation revealed excellent results in 26 cases, good in 24, medium (fair) in 6, middling in one and bad in 4. Follow-up varies between 3 months and 6 years, and it is not possible to present results of 5 years survival because almost all patients have a follow-up of less than 2 years.
