Purpose
The three main treatment modalities used in cancer management are surgery, radiation therapy and chemotherapy. The World Health Organisation recognises that at least 50% of all patients with cancer require radiation therapy at some stage of their disease and up to 60% would benefit from radiation therapy. (1)
Accuracy in treatment preparation and delivery is a important component of modern radiotherapy and requires knowledge and understanding of the technology used in radiotherapy and the site within the body that is irradiated.(2)
One of the factors that presents a considerable relevance in the therapy corresponds to the determination of the immobilization system, in order to allow the patient to remain in the stipulated treatment position, as comfortable as possible, during the time necessary to perform the clinical procedure, throughout all treatments, without compromising their reproducibility.
Immobilization systems are designed both to provide the best therapeutic strategy, as well as to allow the positioning performed to be the most suitable and comfortable for the patient.
Therefore, it is pertinent to assess the relationship between patient comfort and reproducibility, in order to conclude that greater discomfort rates may be associated with variations in positioning, manifested by deviations in reference image consultation, such asportal images or Cone Beam Computed Tomography (CBCT).
Understand the relationship between the comfort manifested by the patient during their positioning in the treatments, and the positional deviations observed to guarantee the reproducibility of the entire treatment.
