BACKGROUND We examined the prognostic value of lymph node density in predicting cancer-specific mortality (CSM) for patients with lymph nodes positive (pN+) laryngeal squamous cell carcinoma (SCC) after laryngectomy. METHODS The records of 156 patients with laryngeal SCC who initially underwent curative resection of the primary tumor combined with neck dissection were reviewed. RESULTS The ...

OBJECTIVE We studied the long-term outcome of radical cystectomy for transitional cell carcinoma and evaluated prognostic factors for disease specific survival. MATERIALS AND METHODS A retrospective review was carried out for all cystectomies performed for transitional cell carcinoma between 1989 and 2002. Disease specific survival was correlated to patient, pathological and operative factors...

BACKGROUND The purpose of this study was to evaluate the utility of lymph node density for predicting the survival of patients with tonsillar cancer and positive neck nodes. METHODS We reviewed data for 64 patients diagnosed with tonsillar cancer with lymph node metastasis in a retrospective single center audit. RESULTS Lymph node density (≥0.05), extracapsular spread (ECS), number of ECS (...

We propose a weighted-density connected dominating set (wDCDS) based data gathering algorithm for wireless sensor networks. The wDCDS is constructed using the weighted-density of a sensor node, which is defined as the product of the number of neighbors available for the node and the fraction of the initially supplied energy available for the node. A data gathering tree (wDCDS-DG tree) rooted at...
