BACKGROUND Despite better prognosis, there is a group of oropharyngeal squamous cell carcinoma (SCC) human papillomavirus (HPV)+ patients who experience treatment failure and succumb to distant metastasis. METHODS Seventy-eight previously untreated patients nested in a concurrent chemoradiation protocol were reviewed to correlate patterns of(More)
BACKGROUND Radiotherapy, a cornerstone of head and neck cancer treatment, causes substantial morbidity to normal adjoining bone. The authors assessed the radioprotective effect of amifostine therapy on the mineralization of the mandible using micro-computed tomography. They hypothesized that amifostine would safeguard the mandible from radiation-induced(More)
OBJECTIVE Descriptions of mandibular distraction osteogenesis for tissue replacement after oncologic resection or for defects caused by osteoradionecrosis have been limited. Previous work demonstrated radiation decreases union formation, cellularity and mineral density in mandibular distraction osteogenesis. The authors posit that intermittent systemic(More)
BACKGROUND The use of mandibular distraction osteogenesis (MDO) for tissue replacement after oncologic resection or for defects caused by osteoradionecrosis has been described but, in fact, has seen limited clinical utility. Previous laboratory work has shown that radiation (XRT) causes decreased union formation, decreased cellularity, and decreased mineral(More)
PURPOSE Adjuvant radiotherapy in the management of head and neck cancer remains severely debilitating. Fortunately, newly developed agents aimed at decreasing radiation-induced damage have shown great promise. Amifostine (AMF) is a compound, which confers radio-protection to the exposed normal tissues, such as bone. Our intent is to utilize Raman(More)
BACKGROUND The current American Joint Committee on Cancer (AJCC) staging system may not accurately reflect survival in patients with human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (SCC). The purpose of this study was to develop a system that more precisely predicts survival. METHODS CT scans from 156 patients who underwent(More)
BACKGROUND We recently described the imaging characteristics of multiple confluent regional metastases (matted nodes) and found that this characteristic was associated with distant metastasis in patients with oropharyngeal squamous cell carcinoma (SCC). The purpose of this study was to determine if matted nodes are a predictive marker for distant(More)
IMPORTANCE This study describes the effect of adjuvant treatment on shoulder-related quality of life, leisure activities, and employment for patients undergoing neck dissection for head and neck cancer. OBJECTIVE To explore the association between treatment outcome and shoulder-related on critical daily life functions such as employment and recreation. (More)
The advent of stem cell-based therapies makes current models of mandibular distraction osteogenesis unwieldy. We thereby designed an isogenic model of distraction osteogenesis whose purpose was to allow for the free transfer of cells and components between rats. As immune response plays a significant role in healing and prevention of infection, an(More)
IMPORTANCE Understanding the drainage patterns to the retropharyngeal lymph nodes is an important consideration in oropharyngeal squamous cell carcinoma (OPSCC) because treatment of these nodes is related to increased morbidity. Prediction of these drainage patterns could not only help minimize treatment morbidity but also prevent failures in at-risk(More)
