Fatigue following head and neck cancer radiotherapy: a systematic review of dose correlates.

Introductions: Radical radiotherapy (RT) is the cornerstone of Head and Neck (H&N) cancer treatment, but it often leads to fatigue due to irradiation of brain structures, impacting patient quality of life.

Objective: This study aimed to systematically investigate the dose correlates of fatigue after H&N RT in brain structures.

Methods: The systematic review included studies that examined the correlation between fatigue outcomes in H&N cancer patients undergoing RT at different time intervals and brain structures.
