OBJECTIVES To assess the feasibility and safety of performing robot-assisted resections of head and neck tumors, and to predict which variables lead to successful robot-assisted resection and better functional outcome. DESIGN Prospective nonrandomized clinical trial. SETTING Academic tertiary referral center. PATIENTS Thirty-six patients with oral(More)
From 1984 through 1992, staff at The Marine Mammal Center (TMMC, Sausalito, California, USA) examined 207 northern elephant seals (Mirounga angustirostris) with a condition of unknown etiology called northern elephant seal skin disease (NESSD). The skin lesions were characterized by patchy to extensive alopecia and hyperpigmentation, punctate or coalescing(More)
OBJECTIVES/HYPOTHESIS Recent reviews of laryngeal cancer have detected a trend toward reduced survival, linked temporally to an abrupt change in treatment of these patients during the 1990s to nonsurgical regimens. Because organ preservation also is an important goal for hypopharyngeal cancer, we sought to determine treatment trends and survival data for(More)
PURPOSE Extracellular matrix metalloprotease inducer (EMMPRIN) is a tumor surface protein that promotes growth and is overexpressed in head and neck cancer. These features make it a potential therapeutic target for monoclonal antibody (mAb)-based therapy. Because molecular therapy is considered more effective when delivered with conventional cytotoxic(More)
BACKGROUND Detection of regional and distant metastatic disease has significant implications for patient management. Fluorescent imaging may be a useful technique for metastasis detection and removal. METHODS Anti-epidermal growth factor receptor antibody (cetuximab) and isotype-matched control antibody (immunoglobulin G [IgG]) were labeled with a(More)
OBJECTIVE Anatomic identification of parathyroid glands during surgery is challenging and time consuming. We sought to determine whether 5-aminolevulinic acid (5-ALA) could produce parathyroid gland fluorescence to improve their detection in a preclinical model. METHODS Thirty-two rats were administered 0 to 700 mg/kg of 5-ALA by intraperitoneal injection(More)
Optical fluorescent technology has the potential to deliver real time imaging of cancer into the operating room and the clinic. To determine the efficacy of fluorescently labeled anti-vascular endothelial growth factor (VEGF) antibody to be used as a cancer specific optical contrast agent to guide surgical resections, we evaluated the sensitivity and(More)
OBJECTIVE To analyze factors affecting 15-year surgical outcomes of choanal atresia repair. DESIGN Case series. SETTING Tertiary care pediatric hospital. PATIENTS Between April 17, 1996, and March 23, 2010, a total of 42 patients aged 3 days to 15 years underwent endoscopic or transpalatal choanal atresia repair by our pediatric otolaryngology(More)
To evaluate cetuximab treatment in head and neck squamous cell carcinoma xenografts and cell lines, we investigated a preclinical model of head and neck squamous cell carcinoma. Head and neck squamous cell carcinoma cell lines SCC-1, FaDu, CAL27, UM-SCC-5 and UM-SCC-22A were used to generate subcutaneous flank xenografts in SCID mice. Mice were divided into(More)
The HNSCC cell line, FaDu was stably transfected with control vector (FaDu) or with plasmid expressing small interfering RNA against EMMPRIN (FaDu/siE). Tumor cells were treated with bevacizumab (0, 25, 50, and 75 ng/ml) in vitro, and then cell counts were performed at 72 h. For in vivo analysis, tumor cells were xenografted onto the flank of SCID mice, and(More)
