Consensus for a postoperative atlas of sinonasal substructures from a modified Delphi study to guide radiotherapy in sinonasal malignancies.

Background: Sinonasal and skull base tumor surgery-related morbidity has been reduced by the use of endoscopic endonasal skull base surgery (EESBS). Postoperative radiation therapy (poRT) requires precise definition of target volumes. To enhance the accuracy of poRT planning, histological and radiological correlations are necessary to locate the tumor attachment on poRT CT scans.

Prediction of the need of enteral nutrition during radiation therapy for head and neck cancers.

Introduction: Patients with a head and neck (HN) cancer undergoing radiotherapy risk critical weight loss and oral intake reduction leading to enteral nutrition. We developed a predictive model for the need for enteral nutrition during radiotherapy in this setting. Its performances were reported on a real-world multicentric cohort.

Voice quality after surgery or radiotherapy for glottic T1 squamous cell carcinoma: Results of the VOQUAL study.

Purpose: Many series have compared voice quality after radiotherapy or surgery for cT1 glottic carcinoma. Different meta-analyses identify better results for radiotherapy while others do not identify any difference, some finally find a superiority of surgery. The purpose of this study was to compare the voice quality in the long term of patients who underwent transoral surgery versus exclusive irradiation for the treatment of cT1 glottic carcinoma.

Multicriteria optimization of radiation therapy: Towards empowerment and standardization of reverse planning for head and neck squamous cell carcinoma.

Purpose: The purpose of this study was to assess if multicriteria optimization could limit interoperator variability in radiation therapy planning and assess if this method could contribute to target volume coverage and sparing of organ at risk for intensity-modulated curative radiation therapy of head and neck cancers.

Material And Methods: We performed a retrospective analysis on 20 patients treated for an oropharyngeal or oral cavity squamous cell carcinoma. We carried out a comparative dosimetric study of manual plans produced with Precision® software, compared with the plans proposed using the multicriteria optimization method (RayStation®).
