INTRODUCTION: The epidemiology of squamous cell oral cavity and pharyngeal cancers (OCPC) has changed rapidly during the last years, possibly due to an increase of human papilloma virus (HPV) positive tumors and successes in tobacco prevention. Here, we compare incidence and survival of OCPC by HPV-relation of the site in Germany and the United States (US). MATERIALS AND METHODS: Age-standardized and age-specific incidence and 5-year relative survival was estimated using data from population-based cancer registries in Germany and the US Surveillance Epidemiology and End Results (SEER) 13 database...

Oral squamous cell carcinoma (OSCC) is the most common oral and pharyngeal cancer, and is responsible of approximately 3% of cancers in men and 2% in women in the Western World, with increasing incidence rates in developing countries. Early detection by screening is necessary to prevent fatal disease because early, curable lesions are rarely symptomatic. The overall 5-yr survival rate is approximately 50% when surgery, radiation, or both are employed as treatment options, but lymph node involvement greatly influences this estimate, by decreasing the survival rate by about 50%...

We evaluated the efficacy of dose de-escalation to the normal larynx using conformal radiotherapy (CRT) for T1/T2 glottic cancer. For conventional RT (2DRT, n = 38), the laryngeal box received a median equivalent dose in 2 Gy fractions (EQD2) of 66 Gy. For CRT (n = 42; 3D-CRT, 20; intensity-modulated RT, 22), clinical target volume (CTV)1 (gross tumor with a 3-mm margin) and CTV2 (laryngeal box) received median EQD2s of 66.6 Gy and 52.2 Gy, respectively. With a 71-month median follow-up, five-year local control and overall survival rates for 2DRT vs...

The E26 transformation-specific (ETS) family is one of the largest families of transcription factors. Upon activation by MAPK pathway, ETS participates in cell proliferation, differentiation, migration, apoptosis, and metastasis. However, the mechanism by which ETS is deregulated in cancer is unclear. In this study, the authors investigated the role of ETS factor, ETS2, in hypopharyngeal cancer pathogenesis in hypopharyngeal cancer tissues (N = 20) and corresponding non-neoplastic tissues (N = 20). The results showed that expression of ETS2 was increased in cancer tissues as compared with the expression in corresponding non-neoplastic tissues...

Human cytomegalovirus (CMV) is an infectious herpes virus present in approximately 50% of the world's population. Pharyngitis is an uncommon manifestation of CMV infection, and vocal cord immobility (VCI) following CMV pharyngitis is quite rare. An 83-year-old man with well-controlled diabetes mellitus and hypertension was admitted due to dyspnea, odynophagia, and dysphagia. Laryngeal fiberscopy revealed bilateral vocal cords almost fixed at the median position, with mucosal redness, swelling, and edema at the hypopharyngeal area...

BACKGROUND: En bloc excision of cervical chordoma is a technically complex procedure, due to the involvement and closeness of the tumor to the spinal cord, cervical nerve roots, and vertebral arteries. Studies have previously shown that en bloc excision of chordomas with negative margins improves local control and prolongs disease-free survival compared with intralesional excision. True en bloc spondylectomy in the cervical spine is not feasible since bilateral vertebral artery sacrifice is not possible...

Background: Overexpression of proangiogenic vascular endothelial growth factor A family VEGFAxxx is associated with tumor growth and metastasis. The role of the alternatively spliced antiangiogenic family VEGFAxxxb is poorly investigated in head and neck squamous cell carcinomas (HNSCCs). The antiangiogenic isoform binds to bevacizumab and its expression level could influence the treatment response and progression-free survival. In this study, the relative expression of VEGFAxxx and VEGFA165b isoforms and splicing regulatory factors genes was investigated in a series of HNSCCs...
