Results of a phase II study of a PI3K inhibitor in ER-positive breast cancer showed a trend toward improved progression-free survival.
Breast Cancer Targets
The level of stromal tumor-infiltrating lymphocytes (Str-TILs) may influence which treatment is the most effective in women with HER2-positive breast cancer.
In this preview of the 2014 San Antonio Breast Cancer Symposium, we take a look at some of the studies to watch for at this year's event.
Data from the CLEOPATRA trial show that pertuzumab adds nearly 16 months to median survival times when used with trastuzumab and chemo in HER2-positive breast cancer, according to final results presented at the ESMO 2014 Congress.
HER2-positive breast cancer patients treated with targeted therapy and chemo were less likely to have a pathologic complete response if they had a PIK3CA mutation.
An 8-year follow-up of HER2-positive breast cancer patients receiving adjuvant trastuzumab shows an overall low incidence of cardiac events when administered after chemotherapy and radiotherapy.
After surgery, adjuvant therapy with trastuzumab alone works just as well as trastuzumab combined with lapatinib for women with early-stage HER2-positive breast cancer.
A follow-up analysis of gene expression signatures from the CALGB 40601 trial shows that certain HER2-positive early-stage breast cancer patients may not benefit from more aggressive chemotherapy treatments as part of a neoadjuvant regimen, and that patients with HER2-enriched tumors responded best to dual anti-HER2 treatment.
With the goal of helping to standardize and optimize care, ASCO has issued two new clinical guidelines on treating patients with HER2-positive breast cancer.
Dual HER2-targeted treatment with T-DM1 and pertuzumab resulted in positive antitumor activity in patients with HER2-positive, locally advanced or metastatic breast cancer, with an overall response rate of 41%.
