Comparing the M.D. Anderson Symptom and Dysphagia Inventories for Head and Neck Cancer Patients.

Objectives: Where patient-reported outcome measures (PROMs) may be administered at multiple patient visits, it is advantageous to capture these symptoms with as few questions as possible. In this study, the M.D.

Patient-Reported Outcomes-Guided Adaptive Radiation Therapy for Head and Neck Cancer.

Purpose: To identify which patient-reported outcomes (PROs) may be most improved through adaptive radiation therapy (ART) with the goal of reducing toxicity incidence among head and neck cancer patients.

Methods: One hundred fifty-five head and neck cancer patients receiving radical VMAT (chemo)radiotherapy (66-70 Gy in 30-35 fractions) completed the MD Anderson Symptom Inventory, MD Anderson Dysphagia Inventory (MDADI), and Xerostomia Questionnaire while attending routine follow-up clinics between June-October 2019. Hierarchical clustering characterized symptom endorsement.

Extended SSD VMAT treatment for total body irradiation.

In this work, we develop a total body irradiation technique that utilizes arc delivery, a buildup spoiler, and inverse optimized multileaf collimator (MLC) motion to shield organs at risk. The current treatment beam model is verified to confirm its applicability at extended source-to-surface distance (SSD). The delivery involves 7-8 volumetric modulated arc therapy arcs delivered to the patient in the supine and prone positions.
