Sights Set on Potential Targeted Treatment for Triple-Negative Breast Cancer

New research shows triple-negative breast cancer tumors may have high levels of a certain protein in common. Identification of this protein may lead to better understanding of how the cancer grows, and how to more effectively treat it in the future. 

T-DM1 May Overcome Resistance to anti-HER2 Medicines Caused by Gene Mutation

Through a subanalysis of data from EMILIA, the clinical trial that led to FDA approval of T-DM1, researchers found that the amount of HER2 messenger RNA (mRNA) present in HER2 positive, metastatic tumors may predict how well that breast cancer will respond to the medicine. Messenger RNA is a type of molecule that carries genetic information to help make proteins. The more mRNA measured on tumor cells, the more HER2 proteins present, and the more responsive those cells will be to T-DM1.

Delayed Time to Surgery Reduces Survival Rates in Young Women

Young women whose surgery-only breast cancer treatment is delayed longer than 6 weeks have decreased survival rates compared with women who are treated sooner.

Health at Diagnosis may Drive Breast Cancer Survival Gap

NEW YORK (Reuters Health) - Differences in the health and tumor characteristics of white and black women with breast cancer at the time of their diagnoses may be largely to blame for the disparity in survival between the two groups, a new study suggests.

Genetic Makeup of Triple-Negative Breast Cancer Explored

A genetic analysis of triple-negative tumors cataloged in The Cancer Genome Atlas found that triple-negative breast cancers can be broken down into two main groups: those that are basal-like, and those that are non-basal-like. 

Response to Early Chemotherapy may Predict Need for Radiation

How breast cancer responds to early chemotherapy may someday help doctors decide the need for radiation therapy based on individuals’ risk of recurrence, a study showed. 

Young Women More Often Choose Mastectomy Over Lumpectomy

Young women who have a choice of surgical treatment choose mastectomy more often than lumpectomy, or breast-conserving treatment, according to a study presented at a major breast cancer conference.

Study Supports Use of Zoledronic Acid for Early Breast Cancer

Researchers found that postmenopausal women who started taking zoledronic acid when they began treatment with the aromatase inhibitor letrozole saw improved bone strength in the spine and hip compared with women who started zoledronic acid after their bone density dropped too low.

Radiation Therapy Raises Risk of Heart Disease

European researchers found that radiation therapy given at any dosage for breast cancer increases a woman’s risk of heart disease, with higher doses leading to higher rates of risk.

Lumpectomy With Radiation Improves Survival in Early-Stage Breast Cancer

A study published in the journal Cancer suggests that women with early-stage breast cancer who have a lumpectomy followed by radiation therapy have at least an equal, if not greater, chance of survival compared with those who have a mastectomy without radiation therapy.
