BACKGROUND Lymph node density (LND) has previously been reported to reliably predict recurrence risk and survival in oral cavity squamous cell carcinoma (OSCC). This multicenter international study was designed to validate the concept of LND in OSCC. METHODS The study included 4254 patients diagnosed as having OSCC. The median follow-up was 41 months.(More)
BACKGROUND The American Joint Committee on Cancer (AJCC) stage III classification of oral cavity squamous cell carcinoma (OCSCC) represents a heterogeneous group of patients with early local disease with regional metastases (T1N1 and T2N1) and advanced local disease with or without regional metastasis (T3N0 and T3N1). OBJECTIVE The aim of this study was(More)
The main goal of the RAC project is to develop a robotic soccer team for the RoboCup small-size league competitions. This paper is focused on two main issues: omnidirectional drive control design and modelling, and robot design and construction. The robot hardware implementation and design options are presented. Based on the robot kinematic model, a motion(More)
BACKGROUND We aimed to study the importance of clinical N classification (cN) in a subgroup of patients with oral cavity squamous cell carcinoma (OSCC) and pathologically negative neck nodes (pN-). METHODS A total of 2,258 patients from 11 cancer centers who underwent neck dissection for OSCC (1990-2011) had pN- disease. The median follow-up was 44(More)
