The lymph node ratio (LNR) combines two types of information—about the extent of neck dissection and about the extent of the pathological examination of the specimen—and thus represents an interesting variable for risk assessment in patients with head and neck cancer. This retrospective study with data from January 1, 1980, to December 31, 2010, evaluates(More)
To evaluate the utility of lymph node ratio (LNR) as a potential prognostic predictor and to test whether LNR may be useful as a potential selection criterion for adjuvant treatment in patients with oropharyngeal squamous cell carcinoma (OPSSC). This retrospective study included 384 patients with regionally metastasized OPSCC who underwent primary surgery(More)

STUDY DESIGN This was a retrospective study that identified 374 patients with OSCC who underwent primary surgery from 1980 to 2010. Of these patients, 148 were identified with(More)
The aim of this study was to investigate B-mode and elastographical ultrasound criteria capable of differentiating between benign and malignant parotid tumours and to define characteristic elastographical patterns for pleomorphic adenomas and Warthin’s tumours. Fifty-seven patients with parotid gland tumours were examined using a combination of B-mode and(More)

BACKGROUND Transoral laser microsurgery (TLM) has led to an expansion of the therapeutic modalities for malignomas of head and neck. This study aims to assess the oncologic results and functional outcomes of TLM in early carcinomas. PATIENTS AND METHODS This is a retrospective study of 947 cases with T1-2 carcinomas primarily managed with laser surgery(More)
BACKGROUND The purpose of this study was to evaluate retrospectively the oncologic results of endoscopic and open surgical techniques in treating T2 glottic carcinomas. METHODS The medical chart of 354 patients with T2 glottic cancer managed with primary surgery were reviewed. Laser microsurgery and frontolateral partial laryngectomy were compared for(More)
