this article reviews the recently published data on the diagnosis of cancer with proteomics, including the major proteomics technologies and promising strategies for biomarker discovery and development. most of the tumor markers are proteins that either numerically increase in response to the alteration of cancer conditions or are produced by cancer cells. however, they are natural compounds o...
Introduction & Objective: Basal cell carcinoma is the most common malignant tumor in humans. The role of ultraviolet radiation is well known in pathogenesis of BCC. More recently some immunohistochemical markers such as p53 gene and Ki-67 antigen are suggested in the pathogenesis. Some of the recent studies correlate these markers to recurrence or metastasis of the tumor. This study is done t...
Background & Aims : This study aimed to explore the correlation of serum level of HER2-neu, CA 15-3, and CEA with TNM staging for breast cancer Material & Methods : In this study serum samples of 50 patients with breast cancer were assessed with ELISA method for level of HER2-neu, CA15-3 and CEA preoperatively.

perivascular epithelioid cell tumor (pecoma) is composed of hmb45+ epithelioid cells with clear to granular cytoplasm and perivascular distribution. we describe a uterine pecoma in a 33 years old woman where tumor cells were positive for hmb45 but negative for epithelial markers and negative or positive for smooth muscles markers.
Background and Objectives: Giant cell Tumor of bone (GCT) is often regarded as a benign tumor, but its clinical course is unpredictable, has a high rate of recurrence, and even can metastases and transform to a malignant tumor. Histological features of the tumor often could not predict its future biologic behavior, so it is just called ''Giant cell tumor'' without indicating maligna...
the value of clinical use of tumor markers cea and ca15-3 for early detection of recurrent breast cancer still is a controversial. this study was investigated relationship between tumor markers cea and ca15-3 and recurrence breast cancer. data regarding 147 women who had breast cancer were entered into the study. patients were reviewed for 120 months after treatment. maximum time for relapse wa...
