In January 1987, the 4th edition of the TNM classification for malignant lung tumours by the International Union Cancer (UICC) came into effect. Thus, for the first time, a uniform worldwide staging system for lung cancer became available. In order to validate the new TNM definitions for lung cancer the data of 3,000 patients were analysed prospectively. Several items were examined: 1) the agre...
BACKGROUND The clinical and neurobiological underpinnings of transient nonmotor (TNM) psychiatric symptoms during the optimization of stimulation parameters in the course of subthalamic nucleus deep brain stimulation (STN-DBS) remain under intense investigation. METHODS Forty-nine patients with refractory Parkinson's disease underwent bilateral STN-DBS implants and were enrolled in a 24-week ...
Purpose Determine which posterior uveal melanoma (PUM) size classification with three categories has the best prognostic discrimination. Methods Single-institution study of 424 consecutive patients with PUM. The tumor's largest basal diameter (LBD), smallest basal diameter (SBD), and thickness (TH) were estimated by fundus mapping and ultrasonography. Tumors were assigned to "small," "medium,...
Revisions in stage grouping of the TNM subsets (T=primary tumor, N=regional lymph nodes, M=distant metastasis) in the International System for Staging Lung Cancer have been adopted by the American Joint Committee on Cancer and the Union Internationale Contre le Cancer. These revisions were made to provide greater specificity for identifying patient groups with similar prognoses and treatment op...
BACKGROUND The prognosis of a gastrointestinal stromal tumor (GIST) is influenced by its anatomic site; however, few studies on the prognosis of gastric GISTs have been reported. The aims of this study were to evaluate long-term prognoses of patients who underwent surgical resection for gastric GISTs and to compare the clinical efficacy of two staging systems: the National Institutes of Health ...
PURPOSE To validate the 8th edition of the American Joint Committee on Cancer/Union for International Cancer Control (AJCC/UICC) TNM staging system for human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC) and investigate whether a modified classification better reflects the prognosis. MATERIALS AND METHODS Medical records of patients diagnosed with non-metastatic H...
BACKGROUND Gastric cancer (GC) is common and its prognosis is often poor due to difficulties in early diagnosis and optimal treatment strategies. TNM staging system is useful in predicting prognosis but only possible after surgery. Therefore, it is desirable to investigate prognostic factors/markers that may predict prognosis before surgery by which helps appropriate management decisions preope...
The aim of this study was to evaluate the treatment and prognosis of gastric gastrointestinal stromal tumors (GISTs) according to the 7th UICC/AJCC tumor-node-metastasis (TNM) system and the modified National Institutes of Health (NIH) risk classification. The study cohort consisted of 1057 patients with gastric GIST who underwent surgery between January 2000 and December 2007 from 13 instituti...
BACKGROUND We hypothesized that incorporation of tumor thickness into the tumor-node-metastasis (TNM) system will provide better prognostic information. Tumors were reclassified as T1 if ≤5-mm thick/≤4-cm diameter, and T2 if >5-mm thick/≤4-cm diameter. METHODS A retrospective analysis was conducted of 322 patients with T1 and T2 oral squamous cell carcinoma (SCC) between 1987 and 2012. Univar...
