Conformal Radiotherapy Facilitates the Delivery of ConcurrentChemotherapy and Radiotherapy: A Case of Primitive NeuroectodermalTumour of the Chest Wall

[摘要] We illustrate the principle of conformal radiotherapy by discussing the case of a patient with a primitive neuroectodermaltumour of the chest wall. Recent advances in radiotherapy planning enable precise localization of the planning target volume(PTV) and normal organs at risk of irradiation. Customized blocks are subsequently designed to produce a treatment fieldthat ‘conforms’ to the PTV. The use of conformal radiotherapy (CRT) in this case facilitated the delivery of concurrentchemotherapy and radiotherapy by significantly reducing the volume of red marrow irradiated.The lack of acute and latetoxicities was attributed to optimal exclusion of normal tissues from the treatment field, made possible by CRT.
