简要总结
In this study, we aim to define the recommended dose of a VEGFR-TKI (pazopanib) in combination with RT pre-operatively given.
详细描述
Study design A dose escalation trial of Pazopanib, starting at 400mg daily, orally in combination with the standard 25 x 2Gy preoperative radiotherapy in newly diagnosed extremity sarcoma patients. Dose of pazopanib will be escalated via 600mg to maximally 800mg. Overall treatment time of pazopanib is 40 days.
Treatment plan: Pazopanib Dose level Dose of pazopanib orally, once daily, # patients
- (starting) 400 mg 3
- 600 mg 3
- (maximum) 800 mg 3
Treatment plan: radiotherapy RT is given during 5 weeks with a once daily fraction of 2 Gray (50 Gray in 25 daily fractions)
RT planning: The dose planning should be performed by CT based Intensity Modulated RT (IMRT) or 3 Dimensional Conformal RT (3D-RT) according to the local planning protocol of the participating institute.
