San Antonio Breast Cancer Symposium

Women with HER2-positive breast cancer and high levels of stromal tumor-infiltrating lymphocytes (S-TILs) treated with chemotherapy alone had an 80% lower likelihood of disease recurrence compared to those with lower TIL counts.

Charles L. Shapiro, MD, discusses the IBIS II trial, which studied anastrozole in preventing breast cancer in postmenopausal women at increased risk of breast cancer.

Brian Leyland-Jones, MBBS, PhD, director of Edith Sanford Breast Cancer Research, discusses the results of the SWOG S0500 trial, which looked at circulating tumor cell (CTC) levels in patients with metastatic breast cancer.

According to results of the Phase III SWOG S0500 clinical trial, switching chemotherapy based on level of elevated CTCs after one cycle of chemotherapy did not improve OS or PFS in women with metastatic breast cancer.

Study investigators reported at the 2013 San Antonio Breast Cancer Symposium that the addition of carboplatin to standard neoadjuvant chemotherapy increased pathologic complete response (pCR) rates in patients with triple-negative breast cancer (TNBC).

According to the results of a prospective, randomized, controlled trial, in women with metastatic breast cancer that responds to frontline chemotherapy, locoregional treatment (LRT) of the primary tumor and axillary nodes does not produce an increase in overall survival (OS).

Findings reported at the 2013 San Antonio Breast Cancer Symposium showed that PIK3CA-mutated tumors in patients with HER2-positive (HER+) breast cancer (BC) are associated with a much lower rate of pathological complete response (pCR).

A new study reported at the 2013 San Antonio Breast Cancer Symposium shows that a prescribed exercise program reduces joint pain in breast cancer survivors taking aromatase inhibitors (AIs), with pain reductions observed at all levels of exercise.

According to newly reported findings from the International Breast Cancer Intervention Study II (IBIS-II), anastrozole may be a new option for primary prevention of breast cancer in postmenopausal women at high risk for the disease.

In women with hormone receptor-positive, HER2-negative metastatic breast cancer, the addition of dasatinib to standard aromatase inhibitor therapy with letrozole doubled progression-free survival (PFS) compared with letrozole alone.

If treated with hormonal therapy and considered to be at low risk for breast cancer recurrence, women aged 65 and older with hormone receptor-positive, axillary node-negative breast cancer may be able to forego radiation therapy (RT) after breast conserving surgery.

Sukumar Nagendran, MD, vice president, medical affairs, Quest Diagnostics, describes BRCAvantage, a test to detect BRCA1 and BRCA2 genes.

Rodrigo Goncalves, MD, postdoctoral fellow, Washington University School of Medicine, discusses the development of a standardized Ki-67 assay.

According to results from the large randomized BETH trial, bevacizumab did not improve invasive disease-free survival (IDFS) or overall survival (OS) when added to adjuvant therapy for HER2-positive breast cancer.

Neil M. Iyengar, MD, discusses a phase II study looking at an omega-3 fatty acid in triple-negative breast cancer (TNBC) survivors.

Massimo Cristofanilli, MD, director, Breast Care Center, Jefferson University Hospitals, discusses molecular subtyping in the diagnosis and treatment of breast can

Pathologic complete response (pCR) to neoadjuvant chemotherapy had a significant correlation with survival in early HER2-positive breast cancer after 4 years of follow-up.

HER2-positive breast cancer may not only be immunogenic but treatment with trastuzumab may also relieve suppression of antitumor immunity, according to new data presented by Sherene Loi, MD, PhD.

According to an analysis of key screening studies presented at the 2013 San Antonio Breast Cancer Symposium, the benefit of screening mammography is more consistent across studies than has previously been thought.

Many important issues will be addressed in the presentations at the 36th San Antonio Breast Cancer Symposium (SABCS), held annually in San Antonio, Texas, this year December 10-14.
