  1. 1. Breast cancer : Multifocality, heterogeneity, and related genetic signatures

    Författare :Gyula Pekar; Dumanski Jan; Sapino Anna; Uppsala universitet; []
    Nyckelord :breast; breast cancer multifocality; molecular phenotypes; intertumoral heterogeneity; biobanking; gene copy number aberrations;

    Sammanfattning : Breast carcinoma often exhibits a complex subgross morphology and may occupy a large volume of the breast tissue and show unifocal, multifocal or diffuse growth patterns. Expression of estrogen- and progesterone receptors, HER2 overexpression, tumor grade, and proliferative activity allows us to classify breast carcinoma into molecular subgroups (Luminal A, Luminal B, HER2-type, triple negative, and basal-like).

  3. 2. Breast tomosynthesis – new perspectives on breast cancer screening

    Författare :Kristina Lång; Malmö Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast cancer; Breast tomosynthesis; Mammography; Breast cancer screening; Cancer detection rate; Recall rate; False positive rate; Image perception; Reading time; Lesion visualisation; Detection error;

    Sammanfattning : Abstract: Mammography is currently the established method in breast cancer screening, although the sensitivity is known be affected by overlapping tissue concealing tumours. Breast tomosynthesis takes advantage of multiple exposures at different angles reducing the negative effect of obscuring tissue. LÄS MER

  4. 3. Tissue Factor Biological Functions : Coagulation Activity in Microparticles and Signaling with Focus On Migration and Apoptosis

    Författare :Mikael Åberg; Agneta Siegbahn; Carl-Henrik Heldin; Teet Velling; Björn Dahlbäck; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tissue factor; Apoptosis; Migration; Chemotaxis; Simvastatin; Platelet Derived Growth Factor; Cell Signaling; Microparticles; Prostasomes; Trombosis; Coagulation; Prostate Cancer; Breast Cancer; Caspase-3; Caspase-8; NFkappaB; PAR2; Transactivation; Monocytes; Clinical chemistry; Klinisk kemi;

    Sammanfattning : Background: Tissue factor (TF) is a 47 kDa transmembrane glycoprotein known as the main initiator of blood coagulation. TF is over-expressed on many malignant cells and apart from increasing the risk of thrombosis, the presence of TF/FVIIa also promotes the progression of cancer and metastasis by intracellular signaling.

  5. 4. Cytogenetic studies of primary and metastatic breast cancer

    Författare :Adewale Adeyinka; Avdelningen för klinisk genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; histokemi; cytokemi; Histologi; tissue culture; cytochemistry; histochemistry; Histology; metastases; prognosis; male breast cancer; breast cancer; trisomy 12; Cytogenetics; chromosomes; vävnadskultur; Clinical genetics; Klinisk genetik;

    Sammanfattning : A series of primary and metastatic breast carcinomas obtained from female and male patients were cytogenetically analysed. Trisomy 12 was identified as a recurrent and sometimes early event in breast carcinogenesis. LÄS MER

  7. 5. TISSUE MICROARRAY PERSPECTIVES ON CYCLIN D1 IN BREAST CANCER: Progression, prognosis and prediction

    Författare :Karin Jirström; Tumörmikromiljö; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pathological anatomy; General pathology; tamoxifen resistance; CCND1; Breast cancer; tissue microarrays; Patologi allmän ; patologisk anatomi;

    Sammanfattning : Breast cancer is a truly heterogenous disease, reflected in the existence of a wide spectrum of phenotypic subsets of tumours with varying intrinsic aggressiveness as well as ability to respond to a given treatment. Recent advances in large-scale genomic and proteomic screening techniques have confirmed this heterogeneity also at a molecular level, but there is still a bottleneck to be overcome before the discoveries in the laboratory can be translated into the much more complex clinical situation in order to develop better targeted therapies.
