In regard to RTOG sarcoma radiation oncologists reach consensus on gross tumor volume and clinical target volume on computed tomographic images for preoperative radiotherapy of primary soft tissue sarcoma of extremity in radiation therapy oncology group studies: In regard to Wang et al (Int J Radiat Oncol Biol Phys 2011;81:e525-e528)

摘要

We commend the RTOG radiation oncologists who arrived at a consensus for target volume delineation for preoperative sarcoma radiation therapy that generally follows the protocol for their recently completed RTOG 0630 trial (1), for which we all await local control results. Of interest is the clinical target volume (CTV) definition, which typically entails a 3-cm longitudinal and 1.5-cm radial margin on GTV (2). Notably however, this longitudinal plane target definition differs from that used in previous prospective trials of pre-operative radiation therapy (RT).
