Capturing acute toxicity data during lung radiotherapy by using a patient-reported assessment tool.

Background: Comprehensive and accurate assessment of symptoms experienced by patients undergoing lung radiotherapy (RT) is challenging. This study aims to evaluate the feasibility and utility of collecting acute toxicity information by using a patient-reported instrument, the Thoracic Symptom Self-Assessment Tool (TSSAT).

Methods: The TSSAT is based on the CTCAE v3.
