Recent advances in delineation of clinical target volume for postoperative 3D-CRT or IMRT in gastric cancer / 中华放射医学与防护杂志

ABSTRACT

The delineation of clinical target volume(CTV)is a critical step in planning three-dimensional conformal radiation therapy(3D-CRT)or intensity-modulated radiation therapy(IMRT)for gastric cancer.Recommendations for target volume construction have been published for two-dimensional(2D)techniques,but are scarce for 3D CT-based CTV contouring.Recent advances and controversies in delineation of postoperative radiotherapy CTV for gastric cancer have been introduced.Further optimization of target volume for postoperative 3D-CRT/IMRT in gastric cancer is necessary.
