Eastern Cooperative Oncology Group (ECOG) trials have demonstrated that recurrence patterns are different for estrogen receptor (ER)-positive vs ER-negative breast cancer. While ER-negative disease carries a high risk for early recurrence—peaking around year 1.5 from diagnosis—risk steadily...
Estrogen receptor (ER)-positive breast cancer often recurs years after the initial diagnosis, and understanding the patterns of timing regarding relapse could identify patients needing more aggressive treatment. At the 2011 San Antonio Breast Cancer Symposium, several investigative teams reported...
James Ingle, MD, of the Mayo Clinic, Rochester, Minnesota, formally discussed the ABCSG-12 and ZO-FAST bisphosphonate studies presented at the 2011 San Antonio Breast Cancer Symposium, noting, “There is a lot of interest in the effect of bisphosphonates on the tumor microenvironment and the impact ...
The story of bisphosphonates, and their disease-modifying potential in breast cancer, is still evolving. While some studies presented at the 2011 San Antonio Breast Cancer Symposium failed to show gains, others found benefits. The theme that is emerging is that bisphosphonates may be most...
Modest benefit reported from AVEREL1 triggered comments among trialists about the future of bevacizumab (Avastin) in breast cancer. “Although there’s controversy about the recent revoking of FDA approval of bevacizumab for metastatic breast cancer, I think there is a consensus in our disappointment ...

According to C. Kent Osborne, MD, of Baylor College of Medicine, Houston, key findings include the following: ...
The availability of effective therapies for HER2-positive tumors has made breast cancer a better managed disease, but outcomes could be further enhanced through the targeting of other players in this pathway, emerging data suggest. C. Kent Osborne, MD, of Baylor College of Medicine, Houston,...
There is an emerging theme in HER2-positive breast cancer: The greater the pathway inhibition, the better the outcome. The latest evidence comes from the phase III Clinical Evaluation of Pertuzumab and Trastuzumab (CLEOPATRA) trial of 808 patients with previously untreated metastatic disease. The...
Women with atypical breast lesions have approximately a 5% to 11% risk of developing breast cancer within 5 years, depending on histology, and this risk can be reduced with chemoprevention, according to a presentation at the 2011 San Antonio Breast Cancer Symposium.1 Investigators tracked the...

Michael P. Link, MD, 2011–2012 President of ASCO and a pediatric oncologist himself (at Stanford University School of Medicine and the Lucile Salter Packard Children’s Hospital at Stanford), said the crizotinib study by Mosse and colleagues has far-ranging implications. “The molecular driver (ALK)...
The value of the targeted agent crizotinib (Xalkori) may not be restricted to the 5% of patients with non–small cell lung cancer who have abnormalities in the ALK gene. In a phase I study conducted by the Children’s Oncology Group consortium, crizotinib halted tumor growth and, in some cases,...
