Iressa Shows Promise For Treatment Of Metastatic Breast Cancer When Combined With Hormonal Therapy
May 20, 2008
By Science Daily
Phase II clinical trial led by researchers at The University of Texas M. D. Anderson Cancer Center showed Gefitinib, the once-promising drug formerly approved as a second line treatment for lung cancer, also known as Iressa, enhanced the effectiveness of hormonal therapy for the treatment of specific types of metastatic breast cancer.These findings are surprising and represent the first positive study for Iressa in breast cancer, as well as for the entire class of drugs known as epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors, said Massimo Cristofanilli, M.D., the study’s principal investigator.
GSK Announces Results of First Phase III Trial Evaluating Tykerb(R) (Lapatinib) Plus Herceptin(R) (Trastuzumab)
May 17, 2008
By PRNews Wire
— Results demonstrating that TYKERB and trastuzumab together resulted
in a clinically meaningful extension of progression-free survival (PFS)
— Combining TYKERB and trastuzumab to attack both the inside and
outside of the HER2 receptor may create a more complete HER2 blockade
— Data demonstrating activity of TYKERB alone despite patients’
previous treatment with multiple lines of trastuzumab and chemotherapy
LONDON and PHILADELPHIA, May 16 /PRNewswire-USNewswire/ –
GlaxoSmithKline today announced positive data from the first-ever
randomized, multi-center, open label Phase III trial of the combination of
two targeted agents, TYKERB and trastuzumab, in women with HER2-positive
metastatic breast cancer

Low Vitamin D May Mean Worse Breast Cancer
May 17, 2008
By Audrey Grayson, ABC NEWS-USA
Vitamin D deficiencies have long been associated with disease, but new research suggests that low levels of vitamin D in women with breast cancer can lead to more aggressive forms of the disease, and even death.Researchers at the University of Toronto studied the correlation between vitamin D levels in the blood, the rate of breast cancer metastases — the incidence of having the cancer spread — and the overall survival rates of 512 women who were diagnosed with breast cancer between 1989 and 1995. The women were followed until 2006.
Embryonic pathway delivers stem cell traits
May 16, 2008
By Cristin Carr, Whitehead Institute for Biomedical Research
CAMBRIDGE, Mass. – Studies of how cancer cells spread have led to a surprising discovery about the creation of cells with adult stem cell characteristics, offering potentially major implications for regenerative medicine and for cancer treatment.
Some cancer cells acquire the ability to migrate through the body by re-activating biological programs that have lain dormant since the embryo stage, as the lab of Whitehead Member Robert Weinberg has helped to demonstrate in recent years. Now scientists in the Weinberg lab have shown that both normal and cancer cells that are induced to follow one of these pathways may gain properties of adult stem cells, including the ability to self-renew
Request for Pre-IDE Determination Meeting with FDA for AdnaGen’s AdnaTest Breast Cancer Device for Detection of Circulating Brea
May 7, 2008
By Business Wire
SAN ANTONIO – OncoVista Innovative Therapies Inc. (OTC BB: OVIT.OB), a biopharmaceutical company engaged in the development and commercialization of targeted cancer therapies, announced the submission of a request to the U.S. Food and Drug Administration for a pre-IDE determination meeting for its AdnaGen AdnaTest Breast Cancer device for the detection of circulating breast tumor cells. AdnaGen is a subsidiary of OncoVista and focuses on the development of innovative tumor diagnostics by utilizing its proprietary technology for the detection and analysis of rare cells.
OncoVista’s Chief Executive Officer, Alexander L. Weis, Ph.D., commented: “We are very pleased to have submitted this package to the FDA. The AdnaTest is intended for use as a prognostic test for women with metastatic breast cancer, in whom the presence of circulating tumor cells is associated with decreased progression-free survival and decreased overall survival and as such can be of tremendous benefit in determining those patients who can best benefit from a certain line of chemotherapy treatment
Molecular Profiling Redefines The Nature Of Malignancy And Increases The Adoption Of Targeted Therapeutics
April 21, 2008
Identification of novel cancer-related targets and pathways is redefining our understanding of the nature of malignancy.
Molecular profiling is prompting new, more detailed classifications of malignancy enabling the development of specific/personalized cancer therapies.
In breast cancer, for example, classification has been extended to include metastatic sites (bone, brain), expression of HEr2, and hormone receptor status.
Standard chemo works better against metastatic BRCA1/2 breast cancer than against sporadic tumors
April 18, 2008
By Emma Mason, European CanCer Organisation (ECCO)
The first study to investigate the effects of chemotherapy on metastatic breast cancer in women with the BRCA1 or BRCA2 gene mutation has shown that standard chemotherapy works better in these patients than in women without the BRCA1/2 mutation.
The authors of a study presented at the 6th European Breast Cancer Conference (EBCC-6) in Berlin found that women with BRCA2-associated breast cancer had a significantly higher response rate, a longer time without the disease progressing, and a longer overall survival when treated with anthracycline-based regimens than did women with sporadic breast cancers that were not associated with BRCA1/2.
Women with BRCA1-associated breast cancer also did better than women with sporadic breast cancer, but the rates were not statistically significant.
New type of drug shrinks primary breast cancer tumors significantly in just 6 weeks

Research provides leads to a new target in cancer treatment — the cancer stem cell
A drug that targets the cell surface receptors that play an important role in many types of cancer can bring about significant tumour regression in breast cancer after only six weeks of use, a scientist told the 6th European Breast Cancer Conference (EBCC-6).
Core Biopsy Appears to Release Breast Cancer Cells to Distant Organs
April 17, 2008
By Kristina Rebelo, DocGuide.com
Evidence has been found of metastatic dissemination after core needle biopsy in an in vivo model of human tumour metastasis, researchers reported in a poster presented here at the Annual Meeting of the American Association for Cancer Research (AACR 2008).
In 2005, the American College of Surgeons Consensus Conference issued an official statement regarding the diagnostic workup of image-detected breast abnormalities, saying that breast cancer treatment should optimised by making a definitive diagnosis prior to entering the operating room. Guidelines include the use of image-guided percutaneous needle biopsy as the gold standard for diagnosing image-detected breast abnormalities.
Several studies have demonstrated tumour cell displacement along needle tracks and into draining lymph nodes following core needle biopsies, but the clinical consequences are a subject of ongoing debate.
