Purpose: This paper describes the protocol for the development of 3D-printed custom applicators in treating skin carcinoma, the evaluation of the materials used, and the methods for segmentation and rendering of the applicators.
Material And Methods: The segmentation and rendering process for the applicator had six phases: (i) determination of the volume of the lesion using a computed tomography (CT) scan; (ii) delineation of the patient surface, using the same CT images; (iii) creation of the applicator in the planner and segmentation of the mold; (iv) preliminary dosimetry and establishment of the route of the catheter from the brachytherapy unit; (v) creation of the 3D applicator using specialized software; and (vi) applicator printing. Following this process, the patient returned for a second CT to undergo the definitive dosimetry with the applicator in place.
Objective/hypothesis: The 10-item Eating-Assessment Tool (EAT-10) is a dysphagia screening test. In HNC patients, screening and diagnosis of dysphagia are not well-established. To determine the metrological properties of the EAT-10 compared with videofluoroscopy in non-surgical HNC-patients and to assess the relationship between EAT-10 scores and patients' self-reported symptoms.

Available evidence suggests that exercise therapy prior to oncological treatment could potentially improve deglutition and quality of life; however, a randomized clinical trial is needed to confirm this observation.
Methods/design: The Redyor study is a single-blind randomized clinical trial designed to compare the effect of prophylactic oropharyngeal exercises on quality of life and dysphagia of 52 patients with HNC referred to the Radiotherapy Department.
