AIM To assess the metastatic topography of intraparotideal and neck lymph nodes in parotid cancer and its influence on tumour recurrence and survival. METHODS The lymph node spread of 142 patients with primary parotid carcinoma treated from 1986 to 2006 was analysed. Disease-free survival (DFS) and overall survival (OS) were calculated. The role of the(More)
Human papillomavirus(HPV)-related head and neck cancer is recognized as a distinct tumor entity with rising incidence reported for several countries. These tumors arise from squamous cells, typically in the oropharynx. In contrast to cancer associated with other risk factors, HPV-related cancer is driven by viral oncoprotein activity and has individual(More)
There are few well-established patient risk factors associated with human papillomavirus (HPV) infection in cancers of the oral cavity and oropharynx. The purpose of this study was to determine if there were significant different risk factors and tumor characteristics between HPV-positive and HPV-negative cancer cases. HPV was evaluated in cancer tissue and(More)
BACKGROUND Oncogenic human papillomaviruses (HPV) DNA have repeatedly been observed in many head and neck carcinomas (HNSCCs), and HPV infections are currently considered a possible factor in the etiology of these tumors. However, the reported prevalences of HPV-DNA in HNSCC are variable. In the current study the authors used highly sensitive polymerase(More)
Although studies have established human papillomaviruses (HPVs) as a risk factor for oral and oropharyngeal cancer, it is not clear whether viral infection affects survival in head and neck malignancies. This investigation examined the relationship between HPV and survival in carcinomas of the oral cavity and oropharynx. Formalin-fixed, paraffin-embedded(More)
OBJECTIVES/HYPOTHESIS Histopathological characteristics of pleomorphic adenomas, especially of capsular alterations such as thin capsule areas, capsule-free regions, capsule penetration, satellite nodules, and pseudopodia in the different subtypes, are described. STUDY DESIGN Prospective unselected series of 100 consecutive cases from 1997 to 2000. (More)
OBJECTIVE To analyze the incidence and risk factors for clinically apparent and occult lymph node metastases in patients with major salivary gland cancers. DESIGN Cohort of patients with a median follow-up of 46 months (range, 1-174 months). SETTING University-based referral center. PATIENTS A total of 160 consecutive patients with complete clinical(More)
CONCLUSIONS The presented results add further support to the observation that laser microsurgery is the preferential surgical treatment for recurrent respiratory papillomatosis (RRP). A meticulous follow-up for early recognition of local recurrence and malignant transformation is recommended. OBJECTIVES Endoscopic microsurgery continues to be the(More)
PURPOSE Quality of life (QOL) should be improved during palliative chemotherapy for end-stage recurrent head and neck cancer. Therefore, we evaluated QOL in head and neck cancer patients during palliative chemotherapy with cisplatin and docetaxel. METHODS Thirty patients were included in a prospective study between 2003 and 2007. Response,(More)
PURPOSE Patients with human papillomavirus (HPV)-containing oropharyngeal squamous cell carcinomas (OSCC) have a better prognosis than patients with HPV-negative OSCC. This may be attributed to different genetic pathways promoting cancer. EXPERIMENTAL DESIGN We used comparative genomic hybridization to identify critical genetic changes in 60 selected(More)
