Hippocampal dose during Linac-based stereotactic radiotherapy for brain metastases: An observational study

2017

Abstract Introduction Aim of the present study is to evaluate homolateral and contralateral hippocampus (H-H, C-H, respectively) dose during Fractionated Stereotactic Radiotherapy (FSRT) or Radiosurgery (SRS) for brain metastases (BM). Materials & methods Patients with BM   3 months, were considered for SRS/FSRT (total dose 15–30 Gy, 1–5 fractions). For each BM, a Flattening Filter Free (FFF) Volumetric Modulated Arc Therapy (VMAT) plan was generated with one or two arcs. Hippocampi were not considered during optimizations phase and were contoured and evaluated retrospectively in terms of dose: the Dmedian, Dmean, D0.1cc and the V1Gy, V2Gy, V5Gy and V10Gy were analyzed. Results From April 2…

Moderate Hypofractionated Postprostatectomy Volumetric Modulated Arc Therapy With Daily Image Guidance (VMAT-IGRT): A Mono-institutional Report on Fe…

2017

The aim of this study was to evaluate the acute toxicity profiles of a moderate hypofractionated regimen with volumetric modulated arc therapy (VMAT) in patients with prostate cancer (PC) who underwent radical prostatectomy.From December 2012 to February 2016, 125 patients, previously having undergone radical prostatectomy, received adjuvant (64 patients) or salvage (61 patients) radiotherapy (RT) inside an institutional protocol of moderate hypofractionation schedule using the VMAT technique (Varian RapidArc, Palo Alto, CA). Eligible patients were 85 years old, with an Eastern Cooperative Oncology Group performance status of 0 to 2, histologically proven adenocarcinoma of the prostate with…

Increased efficacy of stereotactic ablative radiation therapy after bevacizumab in lung oligometastases from colon cancer.

2018

Aim: Metastases from colorectal cancer are poorly responsive to stereotactic ablative radiation therapy (SABR) due to intratumoral hypoxia. Intratumoral oxygenation is improved by administration of angiogenesis inhibitors. Thus, there could be a clinical synergistic effect of SABR with bevacizumab on metastases from colorectal cancer. The aim of this study was to evaluate the feasibility and efficacy of SABR after bevacizumab in lung oligometastases from colon cancer. Methods: The data of patients with lung metastases from colon cancer who underwent SABR were retrospectively evaluated according to the following inclusion criteria: number of metastases ≤3; lung oligometastases from colon can…
