OBJECTIVE In the 1997 TNM staging system, tumors were classified into a single subdivision: T2a, and bilateral tumor involvement (T2b). In the 2002 TNM staging system, tumors are subclassified as T2a (less than one half of one lobe involvement), T2b (more than one half of one lobe involvement), and T2c (bilateral involvement). A recent study questioned the existence of a true pathologic pT2b tu...

BACKGROUND The aim of this study is to develop a prognostic nomogram for patients with adenocarcinoma of esophagogastric junction and compare its predictive accuracy with the traditional tumor-node-metastasis (TNM) malignant staging system. METHODS Patients from the Surveillance, Epidemiology, and End Results Program (from 1988 to 2011) and the First Affiliated Hospital of Xi'an Jiaotong Univ...

Abstract The knowledge of component temperatures during transient operation conditions is essential for an optimal design a gearbox. This because critical peak limit the transferable power as well load capacity. Moreover, understanding thermal behavior gearbox key to improving its efficiency. Therefore, Thermal Network Method (TNM) calculation program WTplus was extended calculate in gearboxes ...

Since January of 2010, the seventh edition of UICC tumor node metastasis (TNM) Classification, which has recently been revised, has been applied to almost all cases of malignant tumors. Compared to previous editions, the merits and demerits of the current revisions were analyzed. Many revisions have been made for criteria for the classification of lymph nodes. In particular, all the cases in wh...

PURPOSE We evaluated urinary collecting system invasion as a prognostic parameter of renal cell carcinoma. MATERIALS AND METHODS A total of 1,124 patients who underwent nephrectomy for a renal tumor at 5 European centers were included in this retrospective study. Several variables were analyzed including urinary collecting system invasion, age, sex, TNM stage, Fuhrman grade, histological subt...

OBJECTIVE Although designated as T4 or M1 in the current TNM classification system revised in 1997, non-small cell lung cancer with ipsilateral pulmonary metastases is treated as a locally advanced disease and reported survival rates are relatively good. We intended to analyze the prognosis of ipsilateral pulmonary metastases and validate current TNM classification system. METHODS Data of 121...

OBJECTIVE There is heterogeneity in the prognosis of gastric cancers staged according to the tumornodes- metastasis (TNM) system. This study evaluated the prognostic potential of an immune score system to supplement the TNM staging system. METHODS An immunohistochemical analysis was conducted to assess the density of T cells, B cells, and myeloid-derived suppressor cells (MDSCs) in cancer tis...
