The study aimed to gather long-term data on the function and complications of patients with nasopharyngeal carcinoma after receiving Intensity-Modulated Radiation Therapy (IMRT) and to identify predictive factors for negative outcomes.
Researchers conducted a longitudinal study, tracking 42 patients' functional performance, speech, and swallowing abilities at multiple time points post-treatment, revealing initial recovery followed by a decline in function years later.
The findings indicated that higher radiation doses were linked to poorer dietary intake and speech understandability, with a notable percentage of patients becoming dependent on feeding tubes five years after treatment.
