Description
Changyou Zhong and co-authors compare two planning styles for lattice radiotherapy in bulky tumors in a study from 2026. Lattice therapy plants high-dose spheres inside a tumor like seeds. When the tumor stretches far head-to-foot, standard arc plans need wide-open jaws. Wide jaws leak dose and blur the lattice pattern.
Their pipe-joint method segments the beam path lengthwise, guided by the beam's-eye view. Nineteen patients with bulky tumors were replanned four ways each. Dose maps for tumor and healthy tissue were scored side by side. Sharper longitudinal control should spare the valleys between dose peaks. Big tumors, the hardest radiotherapy cases, are exactly where such gains matter.
