Adaptive Staged-Dose Gamma Knife Radiosurgery for the Treatment of Large Brain Metastases: Report of 40 Consecutive Cases and Analysis of Literature.

Background: Brain metastases are the most common brain tumors, being one of the most frequent neurological complications of systemic cancer and an important cause of morbidity and mortality. Stereotactic radiosurgery is efficacious and safe in the treatment of brain metastases, with good local control rates and low adverse effects rate. Large brain metastases present some issues in balancing local control and treatment-related toxicity.

Stereotactic Radiosurgery with Gamma Knife in Recurrent Rathke's Cleft Cyst: Case Report and Literature Analysis.

Background: Rathke's cleft cyst is a benign expansive lesion of the sella turcica. If related to clinical disorders, the patient needs surgical treatment.

Objective: To demonstrate the efficacy of radiosurgery in the treatment of relapse of Rathke's cleft cyst as an alternative to surgery.

Gamma Knife Radiosurgery for Treatment of Brain Metastases during the COVID-19 Outbreak.

Introduction: The WHO declared 2019 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) a public health emergency of international concern. The National and Regional Health System has been reorganized, and many oncological patients died during this period or had to interrupt their therapies. This study summarizes a single-centre experience, during the COVID-19 period in Italy, in the treatment of brain metastases with Gamma Knife stereotactic radiosurgery (GKRS).

Radiotherapy for oligometastatic cancer: a survey among radiation oncologists of Lombardy (AIRO-Lombardy), Italy.

Aims: To evaluate the use of radiotherapy (RT) for oligometastatic cancer (OMC) among radiation oncologists in Lombardy, Italy.

Methods And Study Design: A survey with 12 items regarding data of 2016 was sent to all 34 Lombardy RT centers. The survey included six general items and six specific items regarding patient/disease/treatment characteristics.

Pattern of care and outcome in elderly patients with glioblastoma: Data in 151 patients from 3 Lombardia Hospitals.

The appropriate treatment approach for elderly patients with glioblastoma multiforme (GBM) is unclear, although different studies suggest survival benefit in fit patients treated with radiotherapy and chemiotherapy after surgery. We performed a retrospective analysis of 151 patients older than 65years with GBM treated in 3 Lombardia Hospitals. In univariate regression analysis higher KPS (p=0.

Impact of radiotherapy technique on the outcome of early breast cancer treated with conservative surgery: A multicenter observational study on 1,176 patients.

Purpose: To quantify the impact of radiotherapy technique on cosmetic outcome and on 5-year local control rate of early breast cancer treated with conservative surgery and adjuvant radiation.

Methods And Materials: A total of 1,176 patients irradiated to the breast in 1997 were entered by eight centers into a prospective, observational study. Surgical procedure was quadrantectomy in 97% of patients, with axillary dissection performed in 96%; pT-stage was T1 in 81% and T2 in 19% of cases; pN-stage was N0 in 71%, N + (1-3) in 21%, and N + (>3) in 8% of cases.

Are international guidelines for the prescription of adjuvant treatment for early breast cancer followed in clinical practice? Results of a population-based study on 1547 patients.

Aims And Background: The results of several randomized trials and meta-analyses have been reported on adjuvant treatment for early breast cancer and treatment guidelines have been defined accordingly, but detailed data are lacking on the appropriateness of treatment prescription in clinical practice.

Methods: We performed a prospective, observational, multicenter study to monitor the prescription, delivery and effectiveness of radiotherapy following conservative surgery for early breast cancer; 1610 patients treated with postoperative radiation to the breast in 1997 were entered by 12 centers in Lombardy, Italy. Here we report the results of a secondary analysis focused on the prescription of medical adjuvant treatment (1547 eligible patients).
