Objectives The optimal treatment for elderly patients (age > 70 years) with glioblastoma remains controversial. We conducted a prospective trial in 32 consecutive elderly patients with glioblastoma who underwent surgery followed by radiotherapy (RT) plus concomitant and adjuvant temozolomide. Patients and Methods 32 patients 70 years of age or older with a(More)
PURPOSE to investigate the factors affecting survival and toxicity in patients treated with stereotactic radiosurgery (SRS), with special attention to volumes of brain receiving a specific dose (V10 - V16 Gy) as predictors for brain radionecrosis. PATIENTS AND METHODS Two hundred six consecutive patients with 310 cerebral metastases less than 3.5 cm were(More)
PURPOSE To analyze the recurrence patterns in patients with newly diagnosed glioblastoma (GBM) treated with conformal radiotherapy (RT) plus concomitant and adjuvant temozolomide (TMZ), and to compare the patterns of failure according to different target volume delineations. METHODS AND MATERIALS One hundred and five patients with GBM which recurred after(More)
Stereotactic radiosurgery (SRS) delivered in 2–5 fractions (multi-fraction SRS) has been employed in patients with brain metastases as an alternative to single-fraction SRS with the aim to reduce late radiation-induced toxicity while maintaining high local control rate. In the present study we have evaluated the efficacy and toxicity of multi-fraction SRS(More)
OBJECTIVE To assess the long-term efficacy and safety of conventional radiotherapy (RT) in the control of acromegaly according to recent stringent criteria of cure. DESIGN A retrospective longitudinal study. PATIENTS AND METHODS Forty-seven patients with active acromegaly were treated with conventional RT between 1982 and 1994. All patients were first(More)
Epigenetic silencing of the O6-methylguanine-DNA-methyltransferase (MGMT) gene by promoter methylation is correlated with improved progression-free survival (PFS) and overall survival (OS) in adult patients with newly diagnosed glioblastoma multiforme (GBM) who receive alkylating agents. The aim of this study is to determine the correlation between MGMT and(More)
PURPOSE Radiotherapy (RT) and chemotherapy may prolong survival in older patients (age ≥70 years) with glioblastoma multiforme (GBM), although the survival benefits remain poor. This Phase II multicenter study was designed to evaluate the efficacy and safety of an abbreviated course of RT plus concomitant and adjuvant temozolomide (TMZ) in older patients(More)
Glioblastoma is the most frequent primary malignant brain tumor in adults. Postoperative radiotherapy (RT) with concomitant and adjuvant chemotherapy with temozolomide is the standard treatment, however the prognosis remains poor with a median survival in the range of 12-15 months. In recent years, several targeted agents have been developed as potential(More)
Chordoma is a rare, slow-growing, locally aggressive, primary bone tumor that arises from the skull base region in approximately 25–35% of cases. The therapeutic approach to chordoma has traditionally been surgery, followed by radiation therapy. The advent of charged particle radiotherapy has let us consider protons as the postoperative treatment of choice,(More)
Meningiomas located in the region of the base of skull are difficult to access. Complex combined surgical approaches are more likely to achieve complete tumor removal, but frequently at a cost of treatment related high morbidity. Local control following subtotal excision of benign meningiomas can be improved with conventional fractionated external beam(More)
