- 요약Concomitant chemotherapy and radiation treatment (CCRT) for head and neck cancer (HNC) has devastating effects to swallow function, leading to dysphagia in over 2/3 of patients. Acute and long-term alterations to swallow function have detrimental impacts to health status and quality of life, with increased risk of aspiration/aspiration pneumonia, decreased diet tolerance, need for alternative means of nutrition, and increased feelings of isolation and depression reported. CCRT-induced injury to swallow-related structures leads to dysphagia. CCRT induces mitochondrial dysfunction, oxidative stress, microvascular injury, increased inflammatory markers, and tissue remodeling. However, the timing and extent to which tissue injury occurs in swallow-related structures is unclear. Various swallow-based interventions exist to support function/combat CCRT-induced changes. Dysphagia intervention often includes a myriad of exercises and high variability, including: type, duration, and dose of exercise; adherence; timing of implementation. Broadly, intervention has been shown to yield positive outcomes on swallow function in patients treated for HNC. Lingual exercise is a common clinical intervention method for patients diagnosed with HNC. It is often done in conjunction with other exercises and thus isolated impacts are less clear. Some research has been devoted to specifically assessing impacts of lingual exercise in this patient population, however conclusions are limited. Simultaneously, intervention initiation varies, which may impact both acute and long-term outcomes. Reactive intervention is defined as intervention initiated once a patient demonstrates signs or symptoms of dysphagia. In contrast, proactive intervention is defined as intervention initiated prior to the development of deficits, and is used as a way to maintain or support swallow function with the goal of mitigating treatment-induced deficits. It is broadly understood that proactive intervention is preferable, however, there is a lack of standardization and optimization for this patient population. Additionally, numerous factors contribute to the availability of and adherence to proactive intervention for patients, including provider access, education/knowledge of importance of proactive intervention, symptom burden, motivation, etc. Given this gap and limitations of current clinical understanding, this dissertation employed a translational rat model of CCRT to the tongue base, with the addition of a progressive resistance tongue training paradigm at early and delayed time points to assess the impacts of CCRT and timing of intervention implementation on both functional swallow- and related-outcomes as well as underlying peripheral mechanistic changes.This study found that CCRT negatively impacts bolus, tongue, and underlying mechanistic outcomes, and the addition of exercise intervention yields improved outcomes in the setting of CCRT. Early exercise intervention (i.e. proactive) yielded better outcomes compared to delayed intervention, thus indicating the importance of earlier intervention. CCRT to the tongue base resulted in decreased bolus speed, muscle fiber CSA, percent area collagen, and protrusive tongue force 6 months post-CCRT. Lingual exercise increased genioglossus (GG) collagen deposition and muscle fiber CSA, and improved bolus outcomes. The use of early intervention specifically resulted in increased bolus speed and bolus area compared to delayed intervention. In summation, the impacts of CCRT and lingual exercise on swallow function and underlying physiology persist beyond the acute post-treatment phase. This study provided translational evidence that proactive intervention is preferable in improving swallow outcomes and the underlying peripheral mechanism.
