| 内容記述 | Objective: Carbon-ion radiotherapy (CIRT) has demonstrated success in treating radioresistant disease within the head and neck, owing to its unique physical and radiobiological properties. Construction cost remains prohibitive; a center offering only a horizontal port may bridge this difficulty, but removal of the vertical port may prohibit treatment of disease near critical OARs. Building a center only containing a horizontal treatment port has been proposed as one method for cost savings. Methods: Twenty complex cases of head and neck cancer previously treated with conventional CIRT were retrospectively planned using horizontal-port-only treatment incorporating noncoplanar treatment angles to achieve greater degrees of freedom. These were dosimetrically compared with the previous plans. Results: Comparable D95 coverage of both PTV and GTV with ability to meet OAR constraints were feasible with horizontal-port-only treatment. Collectively differences were noted in PTV D95, brain stem Dmax, contralateral eye Dmax and V10 Gy(RBE); further qualitative differences were noted on a plan-by-plan basis dependent on disease location. Conclusions: Horizontal-port-only treatment employing noncoplanar angles was feasible for complicated head and neck disease typically treated with CIRT, though careful consideration is necessary on a plan-by-plan basis. Advances in knowledge: It is worth noting that noncoplanar approaches are not typically used with the current treatment gantry and may extend further the difference between horizontal port planning and a gantry-based gold standard. |
