A 63-year-old woman was referred to a breast surgeon with a breast mass discovered incidentally during follow-up study after colon cancer surgery. Invasive adenocarcinoma was revealed on core needle biopsy. Wide excision of the breast including the tumor was performed. On standard histological examination the tumor showed features of moderately differentiated adenocarcinoma. The immunohistochem...
Background: Breast cancer is a malignant proliferation of epithelial cells that lining the ducts or lobules of the breast. Breast cancer is the second common cancer (after lung cancer) in women. Gallic acid, being a polyphenols, has been reported for its antiproliferative activity against many cancer cell lines. Objective of the present study is effect of gallic acid on proliferation and apopto...
In the present study, various 28 hybrid molecules containing hydrazone and sulfonate moieties were synthesized characterized by FTIR, 1H-NMR, 13C-NMR spectroscopy LC-MS spectrometry, besides elemental analysis. The compounds evaluated for their antiproliferative effects against six cancer cell lines, namely A549 (non-small lung cancer), MCF-7 (breast HT-29 (colorectal adenocarcinoma PC-3 (andro...
In this study, we show that proliferation of breast cancer cells is suppressed by IGF-1–activated JNK MAPK pathway. The molecular mechanism by which c-jun-NH,-kinase (JNK) activation induces antiproliferative signals in IGF-1–stimulated breast cancer cells remains unknown. Tyrosine phosphatase SHP1 is known to negatively regulate signal transduction pathways activated by cell surface receptors ...
Radiation therapy has a solid role in the management of breast adenocarcinoma. It significantly reduces the rates of disease recurrence. Nevertheless, radiation therapy is not without side effects and patients who have undergone breast irradiation are at increased risk for lung disease, sarcomas, acute leukemia and esophageal cancer. We present a case of radiation-induced breast osteosarcoma 29...
Occult breast cancer is defined by the presence of axillary metastases without an identifiable primary breast tumor. Here, we report a rare case of a male occult breast cancer with dermatomyositis. We performed a modified radical mastectomy consisting of whole breast mastectomy and axillary lymph node dissection. Immunohistochemistry and fluorescent in situ hybridization analyses demonstrated a...
frequency of all types of colorectal tumors in the patients referred to selected hospitals in tehran
background colorectal cancer (crc) is one of the most common cancers worldwide which is not extensively researched in iran. objectives the present study aims to investigate the epidemiologic characteristics of crc in patients referred to selected hospitals of tehran university of medical sciences. patients and methods in this descriptive-analytic study 218 patients with colorectal cancer were i...
BACKGROUND The stomach is an infrequent site of breast cancer metastasis. It may prove very difficult to distinguish a breast cancer metastasis to the stomach from a primary gastric cancer on the basis of clinical, endoscopic, radiological and histopathological features. It is important to make this distinction as the basis of treatment for breast cancer metastasis to the stomach is usually wit...
We previously demonstrated a unique protective role for the transient receptor potential, melastatin-2 (TRPM2) cation channel in breast cancer cells. In the present study, we investigated the chemotherapeutic effects elicited by inhibiting this protective role in metastatic breast adenocarcinoma cells. TRPM2 inhibition led to dose-dependent increases in MDA-MB-231 breast adenocarcinoma cell dea...
the present research is a field study in order to investigate scale and ways of doing breast self examination (bse). 270 nurses employed by the medical sciences university’s hospitals related to the ministry of health, and medical education in city of tehran are selected and involved in research on the basis of simple random sampling. the data collection tool was a protrayed questionnaire which...
