Breast Cancer

In this review we describe the current evidence for use of bisphosphonates as part of the adjuvant treatment of patients with early-stage breast cancer.

At present, caution is urged in use of osteoclast-targeted therapy in early-stage breast cancer patients. Not all are at risk for therapy-induced bone loss, and the majority are not at risk for recurrence following adjuvant therapy. Toxicities exist, and there is financial cost to consider.

A new imaging method--optical imaging mammography--is being developed as a tool that aims to provide a better way to identify breast cancer and to monitor patients’ responses to localized treatment.

A large collaborative sequencing study using data from the Cancer Genome Atlas shows basal-like breast cancers share similar genetic origins and features with serous ovarian tumors.

In a study using mouse models, researchers found evidence that metabolic dysregulation induced by dietary factors can stimulate breast growth and confer breast cancer risk.

The FDA has approved an ultrasound device shown to be capable of detecting small masses in dense breasts. The device is indicated for use in combination with mammography for breast cancer screening.

We speak with Clifford Hudis, MD, Memorial Sloan-Kettering Cancer Center, about the recent advances in breast cancer treatment and the top news to come out of this year’s ASCO Breast Cancer Symposium.

Several presentations at the ASCO Breast Cancer Symposium addressed important questions in triple-negative breast cancer: are there promising new treatment approaches for these patients and how can we identify which patients are high risk?

The 18-month results of the phase III BOLERO-2 trial were presented at the ASCO Breast Cancer Symposium, confirming earlier survival results.

Final results of the RIBBON-2 trial show that adding bevacizumab (Avastin) to chemotherapy does not improve overall survival in advanced breast cancer patients who have been previously treated for their metastatic disease.

A new device called MarginProbe may soon be available to help surgeons determine the minimal amount of tissue to be removed during a lumpectomy and reduce re-excision rates.

In this video, Tari A. King, MD, of the Memorial Sloan-Kettering Cancer Center, discusses what to look for at this year’s ASCO Breast Cancer Symposium.

In assessing the value of innovations in breast cancer radiotherapy, it is important to consider not only the basis of their impact on mortality, local recurrence, and cosmesis; emphasis should also be placed on factors such as treatment tolerance, convenience, and delayed morbidities.

With the publication of mature experiences using accelarated partial breast irradiation (APBI) and accelerated whole breast irradiation (AWBI), the use of shortened courses of radiotherapy has become increasingly popular.

Given their greater convenience and, in most cases, decreased costs, APBI and AWBI are becoming increasingly popular alternatives to conventional WBI for early-stage breast cancer patients who desire BCT. However, given the protracted time to local recurrence and complications following BCT, definitive results from randomized clinical trials comparing conventional WBI vs AWBI or APBI are limited.

For appropriate older women screening provides a benefit in this age group by identifying early-stage breast cancer.

Geriatricians would argue that biological age alone should not be used to estimate a patient's anticipated tolerance for cancer therapy.

In this review we will discuss how to evaluate older breast cancer patients, including estimating survival, defining functional limitations, and providing guidelines for optimal adjuvant therapies.

According to a study of 12,500 women treated for invasive breast cancer, treatment with trastuzumab (Herceptin) increases the risk of congestive heart failure and cardiomyopathy.

A new study provides evidence that older women with early-stage breast cancer who undergo radiation therapy following a lumpectomy are less likely to require a subsequent mastectomy.

Given the current rate of progress in this field, it may not be completely unlikely that women with hormone receptor–positive breast cancer will be cured of this disease in the foreseeable future.

It is time to develop more active treatments in the early-disease setting that actually eradicate ER-positive breast cancer before new mutations and secondary resistance have a chance to develop. In this regard, standard chemotherapy is not the answer.

In this article, we describe the long natural history of HR+ breast cancer and review current research and clinical strategies to address this clinical challenge.

Results of a phase III trial show early, promising data that the subcutaneous formulation of trastuzumab (Herceptin) is as efficacious and safe as the intravenous version of the drug.

A new study suggests suppression of breast cancer metastasis relies on an antitumor immune response. Researchers found that administering interferon can reduce bone metastases and increase the survival time of a metastatic breast cancer mouse model.

The FDA approved the mTOR inhibitor everolimus (Afinitor) last week for use in postmenopausal women with HER2-negative, hormone-receptor-positive advanced breast cancer patients.

The diagnosis of central nervous system (CNS) recurrence is a much dreaded outcome among breast cancer patients, and its incidence varies with disease stage and cancer subtype.

CancerNetwork speaks with Patricia S. Steeg, PhD, who has recently written a perspective in the journal Nature calling for a shift in both the types of drugs that are developed for breast cancer and in the way clinical trials are designed and executed.

The last two decades have seen the development of a variety of novel therapeutic agents that have improved prognoses for women with breast cancer.

In this issue of ONCOLOGY, Drs. Lim and Lin present a comprehensive and up-to-date review of the basic biology of breast cancer brain metastasis (BCBM) and of emerging strategies for treating this increasingly common complication of advanced breast cancer (BC) (BC is second only to non–small-cell lung cancer in the frequency of central nervous system [CNS] metastasis.)
