breast carcinoms

Aromatase inhibitors have often been likened to that of 'medical scalpels' for the treatment of breast carcinoma. By inhibiting the singular step of aromatisation, they have proven to be extremely effective allies in the treatment of breast cancer among postmenopausal women. However, their relevance soon may not be limited to the post-menopausal age group alone. Recent studies have hinted at their utility amongst the premenopausal women; combined with ovarian ablation techniques, aromatase inhibitors may prove to be equally effective and more, as compared to tamoxifen in this age-group...

Oncogene-induced senescence is thought to act as a barrier to tumorigenesis by arresting cells at risk of malignant transformation. Nevertheless, numerous findings suggest that senescent cells may conversely promote tumor progression through the development of the senescence-associated secretome they produce. It is likely that the composition and the physiological consequences mediated by the senescence secretome are dependent on the oncogenes that trigger the senescence program. Breast cancer represents a heterogenous disease that can be divided into breast cancer subtypes due to different subsets of genetic and epigenetic abnormalities...

A series of novel quinazoline derivatives have been designed and synthesized, and their inhibitory activities have also been tested against A549 (carcinomic human alveolar basal epithelial cell), MCF-7 (breast cancer) and HeLa (cervical cancer cell). Of these compounds, compound 4t showed the most potent inhibitory activity (IC50=0.22 µg/mL for HeLa, IC50=0.15 µg/mL for A549 and IC50=0.24 µg/mL for MCF-7). Docking simulation had been performed to position compound 4t into the vascular endothelial growth factor receptor (VEGFR) active site to determine the probable binding model...

Breast cancer and lung cancer are the most common tumors that metastasize to iris. The metastasis of iris was generally diagnosed on ophthalmologic examination. In this case, we reported iris metastasis of patients with adenocarcinoma of breast cancer and MRI findings. We report a case of a 51-year-old. She was diagnosed breast cancer two years ago. After adjuvant chemotherapy, radiotherapy and trastuzumab, she was admitted to hospital with the complaints of headache on February 2012. The magnetic resonance imaging (MRI ) revealed multiple brain metastasis...

Several studies have revealed the diagnostic value of fluorodeoxyglucose-positron emission tomography for breast carcinomas. However, breast carcinomas display considerable variation in 18F-labeled 2-fluoro-2-deoxy-D-glucose uptake, and few papers have reported the clinical utility of the standardized uptake values (SUV). The purpose of this study is to investigate the relationship between SUV assessed by positron emission tomography (PET) and the clinicopathological characteristics of breast carcinoma. We reviewed 52 breast carcinomas of 45 patients presented at our department between January 2004 and July 2005...

The literature of breast-screening is vastly large, and enlarges by newer publications permanently. This summary can only be confined to publish data, with arbitrary selection. The mass-screening of complaintless and symptomless persons for early recognition of certain illnesses is to be completed according to district-principles, and to preliminarily agreed criteria. The breast-screening started in 1963 with the HIP-study, since then it is underway in a number of countries of the world. In Hungary, this activity started relatively early, in 1969...

OBJECTIVE: To ivestigate the incidence of neuroendocrine (NE) cells and hormone products in adenocarcinomas and to explore its clinicopathological significance. METHODS: 356 cases of adenocarcinomas were studied by immunocytochemistry with antibodies for chromorgranin and polypeptide hormones. RESULTS: The prevalence of NE cells and hormone products were detected in 54 of 130(41.5%) and 32 of 54 (59.3%) colorectal carcinomas, 38 of 96(39.6%) and 14 of 38 (36.8%) gastric cancer, 8 of 21(38.1%) and 4 of 8(50...

Progranulin (pgrn; PC-cell-derived growth factor, epithelin precursor, or acrogranin) has been identified recently as an autocrine regulator of tumorigenesis in several cancer cells including SW-13 adrenal carcinomas and some breast cancers, but how pgrn promotes tumor progression is not well understood. SW-13 cells do not form tumors in nude mice but become highly tumorigenic when their pgrn expression is elevated, and this provides a useful model in which to investigate the role of pgrn in tumorigenesis. Here we show that, in SW-13 cells, the level of pgrn expression is a major determinant of the intrinsic activity of the mitogen-activated protein kinase, phosphatidylinositol 3'-kinase, and focal adhesion kinase signaling pathways...

Fourier transform infrared spectroscopic study of human breast normal and carcinomal tissues has been carried out. Some distinctive spectral differences which are mainly due to nucleic acids and proteins are observed between normal and carcinomal tissues. This method of analysis results in nearly 100% diagnostic accuracy of carcinomal tissues from normal tissues. The spectral patterns of well-differentiated carcinomal tissues exhibit marked heterogeneity, however that of poorly differentiated carcinomas demonstrate significant similarity...

The results obtained in histochemical examination of the stroma of mammary gland carcinomas allow to draws the following conclusions. The reaction for alkaline phosphatase proved suitable for detecting proliferation zones in the stroma of mammary gland carcinoma. Proliferation of fibroblasts, myofibroblasts, endothelial cells, and possibly also of other cells is involved. At present, myofibroblasts can not be cytoenzymatically differentiated from fibroblasts. The reactions for acid phosphatase and nonspecific esterase provide a quick and reliable picture on the amount of macrophages...

The nitro-imidazole Ro-07-0582, a known radiosensitiser of hypoxic cells in animals, was administered orally to seven patients with metastatic tumour, before irradiation. The delay imposed on the growth of tumour treated in this way was compared to that of tumour in the same patient treated with radiation alone. Two patients died before any assessment of response could be made. Qualitative evidence from a further three patients suggested some enhancement of radiation effect in two patients but not in the third...

1. Women with uterine fibroids do not have an higher cancer risk than women without fibroids. 2. The carcinome of the breast is the most frequent cancer under autopsy cases with uterine fibroids. The carcinoma of the endometrium and of the pancreas are slightly increases, but tumours of other organs are less frequent. 3. The risk of sarcomatous degeneration of uterine fibroids is with 0,6% about fifty more less frequent then the risk of develope another cancer. 4. Hysterectomy does not diminuish the cancer risk of patients with uterine fibroids: Instead of the (not more possibles) cancers of the genital systems there develope tumours in other organs...

By means of fundus photographs of metastatic choroidal carcinomate in 20 patients it is shown that the slightly prominent yellowish-grey (rarely more intense whitish-yellow) areas appear to be either lobular, composed of various nodes, or more homogeneous and solitary. Illustrations are presented of mammary carcinomata (14x), bronchial carcinomata (3x) and uterine carcinomata (3x). The bilateral metastases, occurring in 5 cases, appear all over the eye-ground; the left eye was more frequently affected. Scarring from irradiation (or the use of cytostatics) is followed in the region of the tumour either by pure depigmentation, an almost regular patchy or punctate pigmentation, irregular displacement of pigment such as follows a severe choroiditis disseminata, or a dark, almost regular pigmentation...
