[Prognostic value of PET using 11C-methionine in patients with untreated cerebral gliomas].

We evaluated the prognostic role of positron emission tomography (PET) with 11C-methionine in adults with untreated supratentorial glioma. Histopathologic grading and clinical follow-up data were available from 147 patients with low-grade (n=74) and high-grade gliomas (n=73). Follow-up was conducted until the last clinical contact (n=79) or until death (n=68).

[Results of therapy in Wilms' tumor].

Two hundred seventeen patients (aged under 14) with histologically confirmed Wilms tumor were treated and followed up in 1965-1995. Until 1976 this condition was treated according to the national standard procedures of the time. The SIOP program approach has been introduced ever since.
