For de novo stage IV breast cancer, does resection of the primary tumor improve outcomes? Two studies presented at the 2016 ASCO Annual Meeting reached different conclusions. A prospective randomized study conducted in Turkey concluded there is a survival benefit at 5 years,1 whereas a U.S....
In patients with HER2-positive early breast cancer, pathologic complete response rates after neoadjuvant therapy were higher with docetaxel plus carboplatin plus trastuzumab (Herceptin) plus pertuzumab (Perjeta), or TCH+P, than with ado-trastuzumab emtansine (Kadcyla) plus pertuzumab, or T-DM1+P,...
The risk of recurrence in estrogen receptor–positive breast cancer is known to continue after 5 years, but just how much is that risk once endocrine therapy is stopped? The Early Breast Cancer Trialists’ Collaborative Group (EBCTCG) has concluded it is “appreciable,” with distant recurrences...
In a study of older women with newly diagnosed stage I to III breast cancer, approximately 1 in 5 lost the ability to complete some of the basic tasks necessary for independent living within 1 year of initiating treatment. The study also found that a simple survey can help identify which women are...
Low-dose oral cyclophosphamide plus methotrexate maintenance therapy yielded no disease-free survival benefit in women with hormone receptor–negative early breast cancer, according to the phase III International Breast Cancer Study Group (IBCSG) 22-00 trial. Some evidence of benefit was...
Bacteria that have the potential to abet breast cancer are present in the breasts of cancer patients, while beneficial bacteria are more abundant in healthy breasts, where they may actually be protecting women from cancer, according to Gregor Reid, PhD, of the Lawson Health Research Institute, and...
A review of more than 50 studies (many randomized controlled trials) concluded that surgery and radiation therapy “remain standard-of-care treatment options” in the management of ductal carcinoma in situ.1 The review continues the widely reported discussion on managing ductal carcinoma in situ,...
