RESUMEN
Objective: To investigate patient-reported outcomes of taste alterations and quality of life (QoL) in patients with nasopharyngeal carcinoma (NPC). Methods: In this single-center retrospective study medical records of 191 patients with NPC undergoing chemoradiotherapy (CRT) in the Department of Radiotherapy, Jiangsu Cancer Hospital, the Affiliated Cancer Hospital of Nanjing Medical University from January 2021 to December 2021 were reviewed. A total of 120 patients met eligibility criteria and were included. The taste alterations and QoL at multiple time points during radiotherapy (RT) were compared. Results: There were significant differences in the intensity of taste, discomfort, phantogeusia and parageusia or overall taste alterations at multiple time points during CRT (p-Value<0.001). These four parameters were significantly higher two or four weeks after CRT, or at the end of CRT compared to before CRT (p-Value <0.001). The intensity of taste, discomfort, phantogeusia and parageusia or overall taste alterations were all significantly higher four weeks after CRT compared to two weeks after CRT (p-Value <0.001), and at the end of CRT compared to four weeks after CRT (p-Value <0.001). The chemotherapy-induced taste alteration scale (CiTAS) scores were highest at the end of CRT (p-Value <0.001). There were significant differences in QoL at multiple time points during CRT (p-Value <0.001), and each parameter differed significantly at various time points (p <0.05). The QoL of all areas at the end of CRT were significantly higher than those before CRT, or two or four weeks after CRT (p-Value <0.001). Conclusions: In patients with NPC undergoing CRT, taste alterations increasingly worsen as treatment progresses, with poor QoL outcomes.
