For staging of bone tumors, TNM and Enneking's systems are used with some differences. Magnetic resonance imaging is particularly useful for defining the extent of high-grade tumors, including transcortical and intertrabecular infiltration and periosteal extension. The concepts of compartment and curative surgical margins are important for bone tumor staging.

ovarian cancer is the most lethal gynecological cancer and about 70% of the patients are advanced stagein the time of diagnosis. decision about management (surgical debulking versus neoadjuant chemotherapy) in ovarian cancer patients is dependent on initial staging by abdominopelvic mdct or mri, so, radiologist expertise on ovarian cancer staging is very important. involvement of mesenteric roo...

The tumor-node-metastasis staging system has been the lynchpin of cancer diagnosis, treatment, and prognosis for many years. For meaningful clinical use, an orderly grouping of the T and N categories into a staging system needs to be defined, usually with respect to a time-to-event outcome. This can be reframed as a model selection problem with respect to features arranged on a partially ordere...

introduction: c - reactive protein (crp) is an acute-phase plasma protein that can be used as a marker of activation of the immune system. in response to several inflammatory reactions,the concentration of crp increases and recently have been applicated as a cancer detector in some studies. we aimed to evaluate the relation between crp level and the staging and grading of gastric and colon mali...

a set of one hundred and twenty nine patients with known primary malignancy and suspected brain metastasis was reviewed in present study. the patients were selected among patients presented to the mri section of imam khomeini hospital or a private mri center in tabriz (iran). primary tumor site, clinical manifestations, number and site of lesions were identified in this patient population. the ...

OBJECTIVE To investigate the completeness of tumor, node, and metastasis (TNM) staging for invasive bladder cancer in the Danish Cancer Registry (DCR). METHODS From the DCR, we retrieved data on TNM stage, year of diagnosis, sex, and age of all-incident invasive bladder cancer patients between 2004 and 2009. Data on comorbidity was obtained from the Danish National Patient Register. We estima...
