Introduction: Breast cancer is a cancer that is caused by abnormal growth of breast cells. Modeling and simulation of the growth and treatment of breast cancer, along with providing the possibility of doing experiments and research, can reduce the time and cost of treatment by predicting some cases. The purpose of the present research was to develop an agent-based model for the simulation of b...
in a cross-sectional study aiming to investigate the anatomical distribution of colorectal cancer in a six years period, patients file were studied and 150 patients with colorectal cancer were selected based on age, gender, place of residency, place of anatomical tumor and biological symptom. the findings indicated that 91(59.9) of patients had adenocarcinum, 54 (35.5) pulyp and 7 (4.6) had oth...
Background: Baculoviral inhibitor of apoptosis repeat-containing 5 (BIRC5) gene is an inhibitor of apoptosis that expresses in human embryonic tissues but it is absent in most healthy adult tissues. The copy number of BIRC5 has been indicated to be highly increased in tumor tissues; however, its association with the age of onset in breast cancer is not well understood. Methods: Forty tumor tiss...
Background: Members of the tumor necrosis factor (TNF) superfamily of ligands and their receptors (TNFR) are critical regulators of the adaptive immune system. A proliferation inducing ligand (APRIL) is a member of tumor necrosis factor superfamily. APRIL was identified via database mining in 1998 by Hahne, et al. APRIL allows tumor cells to proliferate at a reasonable rate even in low serum. A...
Introduction: Mesenchymal stem cells (MSCs) are present in most tissues of the body. These cells are involved in various biological processes, such as maintaining tissue homeostasis and wound healing. Recent studies have shown that tumor associated MSCs (TA-MSCs) are also present in tumor microenvironment (TME) of most solid tumors. MSCs have a strong tendency to migration toward tumor tissues....
primary fallopian tube carcinoma is a rare tumor that histologically and clinically resembles epithelial ovarian cancer. here we introduce a case of tubal carcinoma in a postmenopausal woman. the diagnosis of primary fallopian tube carcinoma is rarely considered preoperatively and is usually first appreciated by the pathologist. because of low frequency of tubal carcinoma, there are few systemi...
A case of iris metastasis secondary to prostate cancer is reported and the clinical features of the patient are described. A 75 years old man referred with a right iris tumor , secondary glaucoma and severe anterior uveitis. He had history of multiple bone metastases due to prostate cancer. The iris tumor was diagnosed as prostate cancer metastasis and the literature was searched using medline ...
RAB42, member rat sarcoma oncogene family was proved to play a key role in cancer-promoting progression. However, its function the progression of bladder cancer still uncertain. We explored and pan-cancer using bioinformatics analysis, including expression, prognostic, genetic alteration, functional pathways, tumor microenvironment drug resistance. Our results indicated that expression increase...
background: trace elements play an important role in a number of biological processes. astaxanthin (asx), a carotoid pigment found in certain marine plant and animals, has shown anti cancer and anti free radical properties. this work intended to understand the effect of astaxanthin in breast cancer (invasive ductal carcinoma, idc) by using micro-pixe method. for this aim the concentration of tr...
Introduction: Ovarian cancer is caused by malignant changes in the cells of the ovary. In various studies, cancer has been regarded as a biological system that has a set of characteristics; therefore, presenting a model of this system can considerably help to study and predict the phenomena related to the growth and spread of cancer. This study attempted to model and simulate the growth and spr...
