Chromosomal amplification at 3q is common to multiple human cancers, but has a specific predilection for squamous cell carcinomas (SCC) of mucosal origin. We identified and characterized a novel oncogene, SCC-related oncogene (SCCRO), which is amplified along the 3q26.3 region in human SCC. Amplification and overexpression of SCCRO in these tumors correlate with poor clinical outcome. The importance of SCCRO amplification in malignant transformation is established by the apoptotic response to short hairpin RNA against SCCRO, exclusively in cancer cell lines carrying SCCRO amplification. The oncogenic potential of SCCRO is underscored by its ability to transform fibroblasts (NIH-3T3 cells) in vitro and in vivo. We show that SCCRO regulates Gli1--a key regulator of the hedgehog (HH) pathway. Collectively, these data suggest that SCCRO is a novel component of the HH signaling pathway involved in the malignant transformation of squamous cell lineage

OBJECTIVE: To report a unique presentation of disseminated histoplasmosis. STUDY DESIGN: Case report. SETTING: University hospital, tertiary referral center. PATIENT: Our patient presented with vertigo, tinnitus, and unilateral hearing loss, and was initially found to have a 5-mm enhancing left internal auditory canal mass, as revealed by a magnetic resonance imaging (MRI) scan. Subsequently, the patient developed multiple focal neurologic deficits. INTERVENTIONS: Magnetic resonance imaging and treatment with intravenously administered amphotericin B, with subsequent oral administration of itraconazole. MAIN OUTCOME MEASURES: Clinical presentation and imaging findings of Histoplasmosis involving the cranial nerve VIII. RESULTS: A subsequent MRI scan revealed enlargement of the initial lesion and multiple parenchymal lesions. Further workup revealed a pulmonary lesion; the diagnosis of disseminated histoplasmosis was made on the basis of bronchoalveolar lavage culture. CONCLUSION: Infectious processes, including disseminated histoplasmosis, should be considered in the differential of internal auditory canal masses, especially in the setting of rapid progression of symptoms

OBJECTIVE: The purpose of this study was to compare quality of life issues in patients with advanced laryngeal versus oropharyngeal cancer after treatment with chemoradiation. DESIGN: A cohort study of 31 patients with laryngeal or oropharyngeal squamous cell carcinoma treated with chemoradiation completed the University of Washington quality of life instrument version 4 (UW-QOL v4). Statistical analysis was performed with Wilcoxon rank sum and chi-square tests. SETTING: Academic tertiary care center. RESULTS: Both groups reported similar impairment in the domains of swallowing, chewing, and taste. Oropharyngeal cancer patients reported significantly worse quality of life in the domain of saliva (P < 0.007). CONCLUSION: Swallowing, chewing, and taste were adversely affected by chemoradiation for both groups. Oropharyngeal patients experienced significantly worse problems with saliva than laryngeal patients. These patients reported high levels of satisfaction with health-related quality of life issues. SIGNIFICANCE: Specific head and neck subsites have different morbidities when treated with primary chemoradiation for advanced tumors

We have developed a combined surgical technique involving traction sutures, the harmonic scalpel, and laryngeal nerve monitoring for the removal of mediastinal goiters. This technique is safe, expeditious, and effective; it minimizes the risk of blood loss or nerve injury; and it obviates the need for sternotomy. During a 4-year period, we performed this operation on 21 patients. We observed only two complications: one patient developed postoperative seroma 1 week after surgery and another experienced vocal fold paralysis after intentional sacrifice of the recurrent laryngeal nerve, which was encompassed by cancer. No other recurrent laryngeal nerve was injured. Operative blood loss was negligible, no systemic infection or permanent hypoparathyroidism was observed, and no patient required a chest tube or chest incision. Almost all patients were discharged home on postoperative day 1
