introduction: the adaptive neuro-fuzzy inference system (anfis) is a soft computing model based on neural network precision and fuzzy decision-making advantages, which can highly facilitate diagnostic modeling. in this study we used this model in breast cancer detection. methodology: a set of 1,508 records on cancerous and non-cancerous participant’s risk factors was used.  first, the risk fact...

background: cancer-screening programs are effective in reducing cancer prevalence and mortality; however, cancer remains the leading cause of death in elderly people in korea. the aim of this study was to identify the factors associated with elders’ participation in the national cancer screening program (ncsp) and differences in screening rates by gender. methods: original data from the korea n...

gastrointestinal (gi) cancers are a significant source of morbidity and mortality in iran, with stomach adenocarcinoma as the most common cancer in men and the second common cancer in women. also, some parts of northern iran have one of the highest incidences of esophageal cancer in the world. multi-disciplinary organ-based joint clinics and tumor boards are a well-recognized necessity for mode...

conclusions expression of armc3 in tumor samples and normal adjacent tissue is very important. the expression of this gene in tumor-adjacent tissue may be associated with the stage of cancer; it may be that these tissues are affected by epigenetic and oncogenic changes of breast cancer. accordingly, aberrant expression of armc3 in tumor samples may be an attractive candidate for use as a tumor ...

introduction: as one of the most common cancers among head and neck malignancies, cancer of the oral cavity probably has some variations in countries with a high prevalence of esophageal cancer.  materials and methods: patients with oral cavity cancer who were treated at two tertiary referral centers from january 1999 to january 2009 were included in this study. in addition to demographic data,...

background: brca1 and brca2 genes have been recognized to be responsible for 20-30% of hereditary breast can­cers and approximately 50% of familial breast and ovarian cancers. therefore, the demand for brca1 and brca2 muta­tion screening is rapidly increasing as their identification will affect medical management of people at increased risk. because of high costs involved in analysis of brca1 a...

background: metastasis and recurrence of colorectal cancer after treatment is attributed to stem cells. the aim of this study was to determine the relationship between the expression of stem cell marker cd166 in colorectal cancer by immunohistochemistry and clinicopathologic parameters.methods: from 2006 to 2012, 121 colectomy specimens of patients with colon cancer that were operated in babol ...
