Abstract
To develop an Radiation Therapy Oncology Group (RTOG) atlas delineating gross tumor volume (GTV), and clinical target volume (CTV) to be used for preoperative radiotherapy of primary extremity soft tissue sarcoma (STS).
A consensus meeting was held during the RTOG meeting in January 2010 to reach agreement about GTV and CTV delineation on CT images for preoperative radiotherapy of high-grade large extremity STS. Data were presented to address the local extension of STS. Extensive discussion ensued to develop optimal criteria for GTV and CTV delineation on CT images.
A consensus was reached on appropriate CT-based GTV and CTV. GTV is gross tumor defined by T1 contrast-enhanced MRI images. Fusion of MRI and CT is recommended to delineate the GTV. CTV for high-grade large STS typically includes GTV plus 3 cm margins in the longitudinal directions. If this causes the field to extend beyond the compartment, the field can be shortened to include the end of a compartment. The radial margin from the lesion should be 1.5 cm including any portion of the tumor not confined by an intact fascial barrier, bone or skin surface.
The consensus on GTV and CTV for preoperative radiotherapy of high-grade large extremity STS is available as web-based images as well as descriptive format through the RTOG. This is expected to improve target volume consistency and allow for rigorous evaluation of the benefits and risks of such treatment.
