Five-year long-term functional and quality of life outcomes in total glossectomy survivors.

backgroundTotal glossectomy is proven to be a superior treatment option for advanced tongue cancer. Despite its efficacy, the procedure is associated with profound morbidity, notably impacting Speech, swallowing, and overall quality of life. Limited therapeutic benefits and the potential for considerable morbidity render total glossectomy a subject of controversy.

methodsWe performed a multidimensional quality of life evaluation of long-term (more than 5 yrs.) total glossectomy survivors. In this study, we evaluated 25 total glossectomy survivors with comprehensive functional and quality of life outcomes using objective measures (London Speech Evaluation Scale, FOIS, 100 ml Water Challenge, FEES) and Patient-reported outcomes (SHI, PSS HN, EORTC QLQ 30 & HN35).

resultsEORTC QLQ 30 showed overall good global health status (M = 80 ± 20) and functional scale mean scores ranging from 87 to 91, despite issues in pain (M = 31.6 ± 31), swallowing (M = 23.3 ± 24), and Speech (26.1 ± 1). Speech outcomes revealed 80% with moderate to severe intelligibility impairment. Swallowing outcomes showed 84% requiring special food preparation, 24% exhibiting aspiration, and 72% having pharyngeal residue. Speech outcomes showed 88% having moderate-severe speech impairment, and Patient-reported speech outcomes indicated a mean SHI score of (M = 47.2 ± 42).

conclusionPatients undergoing total glossectomy report favourable long-term outcomes in global health-related quality of life despite moderate to severe impairments in objective speech and swallowing evaluations. These positive patient-reported outcomes support the consideration of total glossectomy as a viable treatment option if and when required, underscoring the importance of evaluating treatment outcomes through the patient-perceived quality of life.
