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)

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)
Many patients with advanced head and neck cancer are already in a poor nutritional status and need supportive nutritional therapy at the time of initial diagnosis. Malnutrition is associated with delayed recovery, prolonged hospital stay and unfavorable prognosis. By using percutaneous endoscopic gastrostomy (PEG), the social stigmatization for the patient(More)
