background: our study aims to determine the correlation between breast cancer tumor size according to imaging (ultrasonography and mammography) with final pathologic report as a gold standard. methods: we included 132 women with pathologically proven invasive breast cancer between april 2011 and december 2013. study variables included tumor size according to pathology (as a gold standard), ultr...

background: breast cancer (bc) is the second most commonly diagnosed cancer after lung cancer. survival of bc patients is affected by intermediate events. this study was aimed to investigate the disease course of primary non-metastatic bc patients with first recurrence of the tumor (frt) as the intermediate event using the illness- death model. methods: this retrospective cohort study was condu...

background: new blood vessels formation is a critical step in tumor progression. vascular density affects the clinical outcome and prognosis of malignant tumors. the aim of this study was to investigate the relation between the vascular endothelial growth factor (vegf) expression and vascular density with the clinical and histopathologic features in oral squamous cell carcinoma (oscc).   method...

background and objectives: involvement of lymph nodes is an important prognostic factor in the most cancers, including colorectal cancer. in the recent years, invasion to blood and lymphatic vessels has been shown to predict involvement of lymph nodes and the number of involved nodes has been less studied issue. the aim of this study was determination of the relationship between the size of col...

background:  giant cell tumor of tendon sheath (gctts) is often thought of as a volar finger mass. we hypothesized that gctts are equally common on the dorsal and volar aspects of the hand. in addition, we hypothesized that there are no factors associated with the location (volar versus dorsal) and largest measured dimension of a gctts.  methods:  a total of 126 patients with a pathological dia...

background: papillary thyroid carcinoma (ptc), occurs mostly in women and sex hormones may play a role in the pathogenesis and clinical course. the objective of this study was to determine the status and prevalence of estrogen and progesterone receptors in ptc with regard to age, gender, tumor size and lymph node involvement. methods: immunohistochemical stains were performed on 92 tissue block...

background : meningiomas are common benign tumors of the central nervous system. patients with meningiomas achieve postoperative optimal functional recovery, but there is a probability of tumor recurrence months or years after surgical resection. this study aims to evaluate the prevalence of recurrent meningioma and the correlation between tumor recurrence and certain factors. materials and met...

Background: New blood vessels formation is a critical step in tumor progression. Vascular density affects the clinical outcome and prognosis of malignant tumors. The aim of this study was to investigate the relation between the Vascular Endothelial Growth Factor (VEGF) expression and vascular density with the clinical and histopathologic features in oral squamous cell carcinoma (OSCC). &nbsp...
