... Abstract Delineation of the targets for intensity-modulated radiation therapy (IMRT) of the head and neck is a crucial step in treatment planning, determining the risks of marginal or out-of-field local/regional recurrences. Delineation of the gross tumor volumes needs to take into account both...

... not pinpoint the limitations of autotransplantation. Head and neck reconstruction is probably the field where autologous free tissue transfer falls short in spite of the revolutionary role. Unlike the hand, specialized head and neck structures such as the tongue, eyes, nose, etc., may not be reconstructed...

.... In the present study, we found a high expression of JAM-A in head and neck squamous cell carcinoma (HNSCC) as well as β-catenin in immunohistochemistry. The expression of JAM-A and β-catenin was of a low level in differentiation-induced cancer pearl regions of HNSCC. Real-time PCR showed the high expression...

... Abstract Human papillomavirus (HPV)-related head and neck malignancies (HNMs) have become a serious health risk over the past 20 years. Despite decreases in non-HPV-related HNMs, the incidence of HPV-related HNMs has skyrocketed, and a new form of tumorigenesis is developing. HPV type 16...

.... Depending on the area of the skull base that is to be accessed, the neck may be slightly flexed or extended ( fig. 1 ). Access to the frontal sinuses and the most rostral areas of the cranial base is further achieved via the use of angled endoscopes. Injection and Mucosal Decongestion Prior...

... Abstract Ultrasound is a highly valuable method for investigating organs and lesions of the head and neck region. Several diseases have a typical sonographic appearance, such as cysts, neurogenic tumors, or hemangiomas. However, the most common indication for sonography of this region...

... Abstract Head and neck cancer (HNSCC) includes squamous cell carcinomas of the oral cavity,pharynx and larynx. Approximately 38,500 cases of HNSCC are estimated to occur in theUSA in 2004, with 11,000 deaths. HNSCCs represent about 3% of all malignant tumors in theUSA. However, in other parts...

... Abstract Objectives: Little is known about the extent of intratumoral genetic heterogeneity inhead and neck squamous cell carcinoma (HNSCC). Material: Therefore, we examined79 stage III and IV primary HNSCCs and matched lymph node metastases for over- andunderrepresentation of specific...

... Abstract Background/Aims: Squamous cell carcinoma of the head and neck (HNSCC) is the6th most common malignancy worldwide with a 5-year survival that has not improved overthe last 20-25 years. Factors of prognostic significance for this tumour type include the presenceof regional lymph node...
