Methods, systems, and kits for treating breast tissue rely on transferring energy to or from cells lining an individual breast duct. Energy can be introduced into the breast duct, e.g., by filling the duct with an electrically conductive medium and applying radiofrequency energy to the medium. Other energy forms could also be used, such as light, ultrasound, radiation, microwave energy, heat, cold, direct current, and the like. By treating individual breast ducts, cancerous and pre-cancerous conditions originating in the duct can be effectively treated.

Methods and compositions are provided for the identification of expression signatures in ER+ breast cancer cases, where the signatures correlate with responsiveness, or lack thereof, to tamoxifen treatment. The signature profiles are identified based upon sampling of reference breast tissue samples from independent cases of breast cancer and provide a reliable set of molecular criteria for predicting the efficacy of treating a subject with ER+ breast cancer with tamoxifen. Additional methods and compositions are provided for predicting tamoxifen responsiveness in cases of ER+ breast cancer by use of three biomarkers. Two biomarkers display increased expression correlated with tamoxifen response while the third biomarker displays decreased expression correlated with tamoxifen response.

Methods and related systems are described for detection of breast cancer in 3D ultrasound imaging data. Volumetric ultrasound images are obtained by an automated breast ultrasound scanning (ABUS) device. In ABUS images breast cancers appear as dark lesions. When viewed in transversal and sagittal planes, lesions and normal tissue appear similar as in traditional 2D ultrasound. However, architectural distortion and spiculation are frequently seen in the coronal views, and these are strong indicators of the presence of cancer. The described computerized detection (CAD) system combines a dark lesion detector operating in 3D with a detector for spiculation and architectural distortion operating on 2D coronal slices. In this way a sensitive detection method is obtained. Techniques are also described for correlating regions of interest in ultrasound images from different scans such in different scans of the same breast, scans of a patient's right versus left breast, and scans taken at different times. Techniques are also described for correlating regions of interest in ultrasound images and mammography images. Interactive user interfaces are also described for displaying CAD results and for displaying corresponding locations on different images.

A dome for applying a vacuum to a patient's breast is comprised of a generally rigid dome capable of withstanding a pressure differential, with a rim and rim cushion underlying the rim of the dome for supporting a rim from the patient's skin surface. The rim may be generally wider than the dome in order to distribute the attendant forces across a greater surface and avoid tissue damage. A sticky sole underlies the rim cushion and seals the rim cushion to the patient's skin to thereby preserve the vacuum within the dome. The sticky sole may be comprised of any adhesive material or even be achieved through the use of an appropriate material for the rim cushion itself. A portable pump unit is connected to the domes and maintains the vacuum within the domes during a recommended protocol. By using the device in accordance with the prescribed protocol, the growth of cancer cells and tumors within the breasts are inhibited.

The present invention relates to a novel gene, Di12, that is differentially expressed as a 1.35 kb RNA in breast cancer tissues and cell lines, and in several normal tissues. The full length cDNA encodes a protein of 339 amino acids. Antibodies to the gene product were developed to investigate the expression of Di12 in breast cancer cell-lines and tumors. The Di12 protein was found in tissue sections of infiltrating ductal carcinomas (IDCs), but not in benign or normal breast specimens. Di12 wag also present in IDC-breast cancer patient sera, and its expression level increased markedly if IDC was accompanied by lymph node or distal metastases. As IDC constitutes ~70% of breast cancers seen clinically, the level of Di12 expression is useful for diseases diagnosis predicting disease progression and monitoring a therapeutic treatment.

This invention relates to human adipose tissue-derived multipotent adult stem cells. More particularly, the invention relates to human adipose tissue-derived multipotent stem cells, which can be maintained in an undifferentiated state for a long period of time by forming spheres and have high proliferation rates, as well as methods for isolating and maintaining the adult stem cells, and methods for differentiating the multipotent adult stem cells into nerve cells, fat cells, cartilage cells, osteogenic cells and insulin-releasing pancreatic beta-cells. Also, the invention relates to cellular therapeutic agents for treating osteoarthritis, osteoporosis and diabetes and for forming breast tissue, which contain the differentiated cells or the adult stem cells. Although the multipotent stem cells are adult stem cells, they have the ability to differentiate into osteogenic cells, nerve cells, astrocytes, fat cells, chrondrogenic cells or insulin-releasing pancreatic beta-cells, and so are effective in treating osteoporosis, osteoarthritis, nerve disease, diabetes, etc. Also, the stem cells form spheres in a serum-free medium containing CORM-2, and thus can be maintained in an undifferentiated state for a long period of time. Also, the stem cells have very high proliferation rates. Accordingly, the stem cells are useful as cellular therapeutic agents.
