EpCAM and p53 Expressions in Infiltrating Duct Carcinoma of the Breast
Invasive Breast CancerBreast cancer represents the most frequently diagnosed cancer in women. It represents the 5th leading cause of cancer mortality all over the world. In Egypt, breast cancer represents the 2nd most diagnosed cancer among all population. But among Egyptian females it represents the 1st diagnosed cancer representing 32.4%. The main cause of death in breast cancer patients is tumor metastasis. Although only 5-10% of recently diagnosed breast cancer cases show metastasis to distant sites, but still there is a high risk for metastasis in patients with localized primary tumor following successful surgical management. Epithelial cell adhesion molecule (EpCAM) is a cell adhesion molecule. It modifies cadherin mediated cell adhesion and it induces epithelial cell migration and proliferation. Some authors elucidate that EpCAM is involved in metastasis. P53 is a known tumor suppressor gene involved in the control of cell cycle, DNA repair and apoptosis. It's one of the most mutated genes in cancer including breast cancer. Mutant p53 has a big role in tumor progression.
Subzero and Scorpion Trial
Ductal Carcinoma in SituThis is a prospective single-institution pilot study examining the feasibility of performing ultrasound-guided cryoablation to completely ablate breast ductal carcinoma in situ (DCIS). The study is designed such that patients meeting selection criteria will undergo cryoablation followed by surgical resection. The pathology of the surgical specimen will be used to determine the rate of complete tumor ablation. Standard adjuvant therapies otherwise remained unchanged.
Defining the Clinical Potential of Mass Response as a Biomarker for Patient Tumor Sensitivity to...
Stage III Breast CancerStage IV Breast Cancer45 moreThe primary objective of this study, sponsored by Travera in Massachusetts, is to validate whether the mass response biomarker has potential to predict response of patients to specific therapies or therapeutic combinations using isolated tumor cells from varying cancers and biopsy formats.
Diagnostic Study of Early Breast Cancer Using Ultrasound
Ductal Carcinoma In-situThis is a pilot study designed to investigate new techniques to guide the appropriate diagnosis and treatment of Ductal Carcinoma In-situ (DCIS). The microvascularity and stiffness of the lesion may be prognostic factors that can guide the need for more or less extensive therapy or perhaps only imaging follow-up may be needed.
Effects of Diet and Exercise on Ductal Carcinoma in Situ
Ductal Carcinoma In SituBreast CancerThis pilot/feasibility trial seeks to explore whether an acute bout of negative energy balance prior to surgery affects biomarkers of neoplasia. Forty overweight or obese postmenopausal women diagnosed with ductal carcinoma in situ (DCIS) or early stage breast cancer (Stage I or II) who elect mastectomy or lumpectomy will be randomly assigned to 1-of-2 study arms: 1) an Attention Control Group that receives instruction on dietary approaches to correct nutritional deficiencies and progressive resistance training (PRT) that targets the arm ipsilateral to the affected breast; or 2) an Experimental Group that will receive PRT and guidance to correct nutritional deficiencies plus an intensive intervention to promote a 1.5-2 pound/week weight loss through diet, exercise, and behavior modification. This study will explore and contrast changes in body mass index (BMI) observed from enrollment to the time of surgery in the experimental vs. attention control arms, and also monitor changes in energy intake and physical activity. These changes will be studied in relation to the following endpoints: a) changes in select circulating biomarkers and gene expression related to cancer progression, hormonal status, inflammation and other energy-related factors; b) rates of tumor proliferation and apoptosis; c) tumor markers, e.g., insulin receptor, Vascular Epithelial Growth Factor (VEGF), Nuclear Factor kappa beta (NFkB), and phosphoproteins associated with the Convergence of Hormones, Inflammation and Energy-Rated Factors (CHIEF) pathway; and d) functional and health-related outcomes. Because both tumor tissue and blood will be examined from pre-to-post-intervention, this study will provide exciting new data that can elucidate pathways by which energy balance affects breast cancer progression. Although longer term weight loss is recommended for overweight and obese breast cancer survivors, it is not known whether placing the body in a state of negative energy balance will have a favorable impact on the tumor. If beneficial changes in tumor biology and the host environment occur with short-term, pre-surgical weight loss, this study provides proof of concept that weight loss may offer an acceptable and complementary treatment option that could be combined with standard therapies.

Breast CarcinomaBreast Ductal Carcinoma In Situ2 moreThis trial studies the effect of an electronic health (eHealth) support program called PACK Health on patient reported health outcomes in patients with breast cancer. PACK Health monitors breast cancer patients' reported side effects and experience of care when receiving chemotherapy. Participating in the PACK Health coaching program may improve quality of life, decrease hospital admissions and improve overall health.
Zoledronic Acid in Aromatase Inhibitor Induced Musculoskeletal Symptoms
Ductal Carcinoma in SituEstrogen Receptor-positive Breast Cancer6 moreRATIONALE: Zoledronic acid may prevent bone loss and help prevent or lessen musculoskeletal symptoms in women receiving hormone therapy for breast cancer. PURPOSE: This phase II trial is studying how well zoledronic acid works in preventing musculoskeletal symptoms in post-menopausal women with stage I, stage II, or stage III breast cancer receiving letrozole.
Vorinostat in Treating Women With Ductal Carcinoma in Situ of the Breast
Breast CancerRATIONALE: Vorinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PURPOSE: This clinical trial is studying how well vorinostat works in treating women with ductal carcinoma in situ of the breast.
Image-guided Targeted Doxorubicin Delivery With Hyperthermia to Optimize Loco-regional Control in...
Metastatic Breast CancerBreast Cancer6 moreIn this phase I feasibility study, the investigators evaluate the combination of lyso-thermosensitive liposomal doxorubicin (LTLD, ThermoDox) with local hyperthermia and cyclophosphamide (C), for the local treatment of the primary breast tumour in patients with metastatic breast cancer. When heated to 40-43 degrees Celsius (ºC), LTLD releases a very high concentration of doxorubicin locally within seconds. Hyperthermia of the primary tumour will be induced by Magnetic Resonance guided High Intensity Focused Ultrasound (MR-HIFU) on a dedicated Sonalleve MR-HIFU breast system. The investigators hypothesize that by substituting doxorubicin (A) in the AC-chemotherapy regimen for the combination of LTLD and MR-HIFU induced hyperthermia, optimal local tumour control can be achieved without compromising systemic toxicity or efficacy. This will be the first study to evaluate LTLD with MR-HIFU hyperthermia in breast cancer patients.
