The WHO definition of the 3 classes of well differentiated endocrine tumor, well differentiated endocrine carcinoma and poorly differentiated carcinoma, allows an efficient general classification of GEP NETs fitting European Union (EU) current clinical use. The ENETS grading and TNM staging systems are complementary tools allowing to improve patients' stratification, and their adoption is stron...

IMPORTANCE The literature on Merkel cell carcinoma (MCC) of the eyelid remains scarce, and there has yet to be a study using the most up-to-date TNM staging system for this rare but aggressive tumor. OBJECTIVE To analyze the TNM stage, management, and outcomes of patients with MCC of the eyelid. DESIGN, SETTING, AND PARTICIPANTS Retrospective case series of 21 patients from 5 tertiary refer...

The International Staging Committee (ISC) of the International Association for the Study of Lung Cancer (IASLC) collected 68,463 patients with nonsmall cell lung cancer and 13,032 patients with small cell lung cancer, registered or diagnosed from 1990 to 2000, whose records had adequate information for analyzing the tumor, node, metastasis (TNM) classification. The T, N, and M descriptors were ...

Abstract Background Inflammatory response biomarkers have been studied as promising prognostic factors in renal cell carcinoma, but few studies focused on papillary carcinoma (PRCC). This study was performed to evaluate the value of preoperative neutrophil-to-lymphocyte ratio (NLR) PRCC patients. Methods In total, 122 postoperative patients selected from 366 non-clear were enrolled our institut...

The tumor-node-metastasis (TNM) staging system for lung cancer has been modified since its first edition in the late 1960s. Its seventh edition has been recently published and, for the first time, a truly worldwide database was analyzed in order to propose modifications in the staging. Significant changes have been made in the tumor and metastasis descriptors. Although the recommendations for t...

Novel biomarkers are required to improve prognostic predictions obtained with lung cancer staging systems. This study of 62 surgically-treated Non-Small Cell Lung Cancer (NSCLC) patients had two objectives: i) to compare the predictive value of T-stage classifications between the 6(th) and 7(th) editions of the Tumor, Node, and Metastasis staging system (TNM); and ii) to examine the association...

Magnetic nanoparticles have proven to be extremely useful in a broad range of biomedical applications. To ensure optimal efficiency, precise characterization these particles is required. Thermal Noise Magnetrometry (TNM) recently developed technique that has already been validated against other techniques. TNM offers unique advantage no external excitation the system required drive measurement....

The 8th edition of the TNM was released in 2016 and included major revisions, especially for stage III. We aimed to compare the prognostic value of the 7th and 8th editions of the AJCC TNM classification for stage III gastric cancer. Clinical data from 1557 patients operated on for stage III gastric cancer according to the 7th edition between 2007 and 2014 were analyzed and compared using the 7...

PURPOSE Unequivocal pathologic markers for the prognosis of pancreatic endocrine tumors are often lacking. Suggestions for prognostic guidance include the WHO classification. Recently, a tumor-node-metastasis (TNM) staging system was proposed. We evaluate this system, as well as assess other potential prognostic factors such as tumor Ki67, size, endocrine syndrome, heredity, body mass index (BM...

Objective of the study is to review the current 7th edition of the TNM classification of renal tumors and to perform a critical analysis of the recent evidence in order to identify the limitations of this new staging system. A search of the english literature was performed through the Medline and Pubmed database using the following keywords: renal cell carcinoma, staging system and TNM. Overa...
