A number of risk-group stratification or staging systems have been found useful at stratifying patients with differentiated thyroid carcinoma into risk groups. Those identified as high risk could be subjected to more aggressive treatment, while those at low risk could be spared of such treatment. However, the best stratification system in patients with follicular thyroid carcinoma (FTC) remains...

The latest revision of the International System for Staging Lung Cancer was published in June 1997. We discuss the following 4 major items in the new TNM staging system. 1) The fact that stage I was divided into stage IA (T1N0M0) and IB (T2N0M0) is reasonable, as the survival prospects for the subsets differ significantly. 2) The fact that stage II was divided into stage IIA (T1N1M0) and IIB (T...

Objective This study is to establish a new staging system for nasopharyngeal carcinoma (NPC) based on the magnetic resonance imaging (MRI) and intensity-modulated radiation therapy (IMRT). Methods Totally 492 patients with nasopharyngeal carcinoma were included in this study. These patients were diagnosed by pathological detection (without distant metastasis) and underwent the initial treatme...

We evaluated the prognostic significance of five staging systems in 470 consecutive, previously untreated patients with multiple myeloma diagnosed between 1989 and 2006. The five staging systems were those proposed by Durie and Salmon, Bataille et al., the South West Oncology Group, Weber et al. and the International Staging System. This last proved to be superior to the others.

Optimal treatment policies of maxillary sinus carcinoma remain to be defined. In this study 20 cases of maxillary sinus malignant tumors in the past 10 years were retrospectively reviwed. The most common histopathological diagnosis were squamous cell carcinoma. All patients were staged clinically according to the 1997 AJCC staging systems. The T classification of the tumors of the patients was ...

HYPOTHESIS A gastrointestinal stromal tumor (GIST) staging system can be created with the Surveillance, Epidemiology and End Results (SEER) database. DESIGN A review of records in the SEER database from 2537 patients with GISTs from June 1, 1977, through August 1, 2004. PATIENTS AND METHODS Patients were compared using all available clinicopathologic factors, and a TGM (tumor, grade, metast...
