Stereotactic Body Radiation Therapy for Mediastinal and Hilar
WebNov 15, 2016 · Normal tissue constraints are respected during treatment planning. When treating in three fractions, the volumes of liver receiving 21 Gy (V 21) or more and 15 Gy (V 15) or more are kept below 30 and 50 %, respectively. The corresponding doses to these volumes in single fraction would be V 12 and V 7 [ 42 ]. WebIn this algorithm, the prescription dose of the dose-escalation plan was escalated before violating any organ-at-risk (OAR) dose constraint. Dose metrics for 3 targets (gross target volume [GTV], tumor vessel interface [TVI], and dose-escalated planning target volume [DE-PTV]) and 9 OARs (duodenum, large bowel, small bowel, stomach, spinal cord ... WebGiven these toxicities, a follow-up Phase II study from Stanford of 20 patients with locally advanced pancreatic cancer was conducted with priority given to meeting duodenal constraints. 13 This study also transitioned treatment to linear accelerator (linac)-based SBRT with IMRT. The protocol continued to use a 25 Gy single fraction SBRT regimen. dr hennings office
