Radiosurgery with or without A 2-mm margin for 93 single brain metastases.
Int J Radiat Oncol Biol Phys
March 2008
Purpose: Retrospective comparison of Linac radiosurgery (RS) in 93 single brain metastases with or without a 2-mm margin.
Patients And Methods: A total of 153 patients had Linac RS (between April 1992 and June 2004), with 139 patients (90.8%) evaluable in June 2005.
Purpose: To study the impact of fused (18)F-fluoro-deoxy-D-glucose (FDG)-hybrid positron emission tomography (PET) and computed tomography (CT) images on conformal radiotherapy planning for esophageal carcinoma patients.
Methods And Materials: Thirty-four esophageal carcinoma patients were referred for concomitant radiotherapy and chemotherapy with radical intent. Each patient underwent CT and FDG-hybrid PET for simulation treatment in the same treatment position.
Article Synopsis
- The study investigates how combining PET and CT imaging impacts radiotherapy planning for non-small-cell lung cancer patients.
- A total of 101 patients were analyzed, with PET imaging revealing additional metastatic disease in 8 patients, affecting their eligibility for curative treatment.
- Image fusion resulted in significant changes in tumor volume estimates for many patients, with 23% experiencing a decrease and 26% an increase in gross tumor volume, highlighting its importance in treatment planning.
