Intraoperative Radiotherapy With INTRABEAM: Technical and Dosimetric Considerations
Methods and materials: Dose measurements were performed for a low energy (50 kV) X-ray INTRABEAM source. For spherical, flat, surface, and needle applicators, the following dosimetric parameters were measured: depth-dose (DD) profiles, surface dose (Ds), output factors (OF), and target dose homogeneity (DH). Optical density versus exposure calibration films were employed to obtain 2-dimensional...
متن کاملIntraoperative radiotherapy (IORT) for breast cancer using the Intrabeam system.
INTRODUCTION Intraoperative radiotherapy (IORT) with low-energy X-rays (30-50 KV) is an innovative technique that can be used both for accelerated partial breast irradiation (APBI) and intraoperative boosting in patients affected by breast cancer. Immediately after tumor resection the tumor bed can be treated with low-distance X-rays by a single high dose. Whereas often a geographic miss in cov...
متن کاملHigh relapse-free survival after preoperative and intraoperative radiotherapy and resection for sulcus superior tumors.
STUDY OBJECTIVES Relapse-free survival in patients with sulcus superior tumors. DESIGN Prospective registration study. SETTING Department of surgical oncology of a university hospital. PATIENTS Twenty-one patients treated with preoperative radiotherapy (46 Gy), lobectomy and chest-wall resection, and intraoperative radiotherapy (10 Gy).

متن کاملImmunotherapy Combined with Large Fractions of Radiotherapy: Stereotactic Radiosurgery for Brain Metastases—Implications for Intraoperative Radiotherapy after Resection
Brain metastases (BM) affect approximately a third of all cancer patients with systemic disease. Treatment options include surgery, whole-brain radiotherapy, or stereotactic radiosurgery (SRS) while chemotherapy has only limited activity. In cases where patients undergo resection before irradiation, intraoperative radiotherapy (IORT) to the tumor bed may be an alternative modality, which would ...
متن کاملResection of Pediatric Brain Tumors: Intraoperative Ultrasound Revisited
BACKGROUND Extent of resection is a very important prognostic marker in most pediatric brain tumors. Intraoperative imaging facilitates resection control. Intraoperative ultrasound (IOUS) is a cost-effective alternative to intraoperative magnetic resonance, but scant literature addresses its utility in this context. METHODS We retrospectively reviewed all pediatric brain tumors operated at ou...
