Image-guided radiation therapy (IGRT) in gastrointestinal tumors.
CONTEXT Daily setup errors and changes in body habitus during external beam radiotherapy can result in interfraction variation, contributing to uncertainties in treatment delivery. The conventional method of patient positioning using external skin markings is inadequate in reducing these interfraction variations. OBJECTIVE To evaluate use of on-board imaging with daily kV-kV image matching to...
متن کاملAssociation between radiation pneumonitis and tumor response in patients with NSCLC treated with chemoradiation
Dang and colleagues recently reported in the journal that tumor response to definitive chemoradiation, as assessed using the RECIST criteria, and the risk of radiation pneumonitis were positively correlated in patients with non-small cell lung cancer (NSCLC). We had previously reported similar findings in a study that used positron tomography both to measure tumor response and to assess normal ...
متن کاملHow accurate is image guided radiation therapy (IGRT) delivered with a micro-irradiator?
There is significant interest in delivering precisely targeted small-volume radiation treatments, in the pre-clinical setting, to study dose-volume relationships with tumor control and normal tissue damage. In this work we investigate the IGRT targeting accuracy of the XRad225Cx system from Precision x-Ray using high resolution 3D dosimetry techniques. Initial results revealed a significant tar...
متن کاملComparison of 5FU-base Chemoradiation with and without Eloxatin on Pathologic Complete Response in Neoadjuvant Chemoradiation of Rectal cancer
Background and Objectives: To compare pathologic complete response (pCR) in patients with advanced rectal cancer receiving neoadjuvant chemoradiotherapy (NACT) by 5-FU or Xeloda (capecitabine) with and without Eloxatin (oxaloplatin injection). Materials and Methods: Seventy-five consecutive patients with the diagnosis of advanced rectal adenocarcinoma were included. Two basic chemotherapy r...
متن کاملTomotherapy as a tool in image-guided radiation therapy (IGRT): theoretical and technological aspects
Helical tomotherapy (HT) is a novel treatment approach that combines Intensity-Modulate Radiation Therapy (IMRT) delivery with in-built image guidance using megavoltage (MV) CT scanning. The technique utilises a 6 MV linear accelerator mounted on a CT type ring gantry. The beam is collimated to a fan beam, which is intensity modulated using a binary multileaf collimator (MLC). As the patient ad...
