BACKGROUND The stage of esophageal cancer is currently determined by the anatomic TNM classification system as opposed to information about tumor biology. METHODS A retrospective review was made of a prospective electronic database. Patients had esophageal cancer, dedicated positron emission tomography (PET) using F-18-fluorodeoxyglucose (FDG-PET) and maximum standardized uptake value (maxSUV...

As with most cancers the prognosis in pharyngeal and oral cavity cancer largely depends on tumour stage. Physical examination, including endoscopy should be combined with technical radiologic imaging to record the precise extent of tumour. The TNM staging system of the head and neck region is, in fact, an anatomic staging system that describes the anatomic extent of the primary tumour as well a...

Tumour volume is a significant prognostic factor in the treatment of malignant head and neck tumours. Studies of laryngeal and pharyngeal tumours have shown tumour volume to be an important predictor for tumour recurrence. Some studies (for instance nasopharyngeal carcinoma) have shown through multivariate modelling that tumour volume is a dominant covariate that overwhelms T stage, N stage and...

OBJECTIVE To investigate the completeness of TNM (Tumor-Node-Metastasis) staging for prostate cancer (PC) in the Danish Cancer Registry (DCR). METHODS We identified 20,184 men registered with first-time PC in the DCR between 2004 and 2009. These patients were linked to the Danish National Patient Register to obtain data on comorbidity according to the Charlson Comorbidity Index (CCI). We calc...

BACKGROUND AND OBJECTIVES The eighth TNM edition for gastric cancer was released in 2016 and included major revisions, especially of stage III. The purpose of this study was to evaluate the prognostic value of the new AJCC TNM classification in comparison with the 7th edition for stage III gastric cancer. METHODS Clinical and histopathological data on 1,496 patients operated on for stage III ...

BACKGROUND Ubiquitin modification of proteins influences cellular processes relevant to carcinogenesis. CHIP (carboxyl-terminus of Hsc70-interacting protein) is a chaperone-dependent E3 ubiquitin ligase, regulating the stability of heat shock protein 90 (HSP90) interacting proteins. CHIP is implicated in the modulation of estrogen receptor (ESR1) and Her-2/neu (ERBB2) stability. LOX (lysyl-oxid...

PURPOSE The aims of this study were to compare the 7th and 8th editions of the American Joint Committee on Cancer (AJCC) staging manuals on tumor, node, and metastasis (TNM) staging systems and to evaluate whether the 8th edition represents a better refinement of the 7th staging system, when applied for the classification of gastric cancers. MATERIALS AND METHODS A total of 5,507 gastric canc...

The production of beta-galactosidase by Sf9 cells infected with recombinant Autographa californica nucleopolyhedrovirus (AcNPV) was investigated in shake-flask culture using two serum-free basal media: Grace's medium and TNM-FH (Grace's medium supplemented with lactalbumin hydrolysate and yeast extract). At the time of infection, cells grown in serum-supplemented TNM-FH were transferred into fr...

The interaction of glycoprotein 130 (gp130) with the cytokines of Interleukin-6 (IL-6) family has proved to play a crucial part in several cancers. Our current study is designed to discover the clinical prognostic significance of gp130 in non-metastatic gastric cancer. We examined intratumoral gp130 expression in retrospectively enrolled 370 gastric cancer patients who underwent radical gastrec...
