A pre-planned subgroup analysis of data from the MONALEESA-2 trial demonstrated similar clinical benefit and safety profiles in elderly patients compared to younger patients with HR+/HER2-advanced breast cancer, supporting a paradigm shift in the future medical management of these patients from the current standard of letrozole to combined treatment of letrozole plus ribociclib.

Yu (Amy) Zong, Shanghai Jiaotong University School of Medicine, discusses a meta-analysis of nanoparticle albumin-bound paclitaxel as neoadjuvant chemotherapy of breast cancer.&nbsp;

Neoadjuvant chemotherapy with nanoparticle albumin-bound nab-paclitaxel has demonstrated substantial activity across major subgroups of breast cancer, a meta-analysis of clinical trials showed.

The results of a recent randomized study showed anti-HER2 DC1 vaccination to be a safe and immunogenic treatment to induce tumor-specific T-cell responses in patients with HER2-positive breast cancer.

Sibylle Loibl, MD, PhD, discusses the most recent subanalysis of the GeparSepto trial, how the drugs match up in terms of toxicities, and a separate set of data looking at patients with breast cancer who are also pregnant.

Julia White, MD, discusses the upcoming phase II trial, the toxicities associated with the treatment, and the potential for control of these metastases. According to White, the trial is still accruing its 143 patients.

Julia White, MD, professor of Radiation Oncology, Ohio State University, discusses a phase II study of whole brain radiotherapy with concurrent lapatinib in patients with brain metasteses from HER2-positive breast cancer.

Mark D. Pegram, MD, director of the Breast Cancer Oncology Program, Stanford Women&rsquo;s Cancer Center, co-director of Molecular Therapeutics Program, Stanford Medicine, discusses a phase II trial looking at ONT-380 in HER2+ breast cancer.&nbsp;

The phase II HERMIONE trial was halted after the antibody-drug conjugate MM-302 combined with trastuzumab (Herceptin) failed to improve progression-free survival (PFS) versus chemotherapy plus trastuzumab in patents with HER2-positive metastatic breast cancer who had previously received trastuzumab, pertuzumab (Perjeta), and ado-trastuzumab emtansine (T-DM1, Kadcyla).

The 2017 Miami Breast Cancer Conference, to be held March 9 to 12 at the Fontainebleau Miami Beach, welcomes an expanded group of program chairs, and a newly established curriculum committee made up of a multidisciplinary group of breast cancer specialists.

An attempt to strengthen neoadjuvant treatment of patients with locally advanced HR-positive and HER2-positive breast cancer by adding estrogen deprivation therapy to a standard regimen failed to significantly improve response rates.

Higher levels of tumor-infiltrating lymphocytes (TILs) were associated with improvements in overall survival (OS) for patients with advanced HER2-positive breast cancer treated with docetaxel, trastuzumab (Herceptin), and pertuzumab (Perjeta).

Debu Tripathy, MD, chair, Breast Medical Oncology, University of Texas MD Anderson Cancer Center, discusses the potential for immunotherapy in the treatment of HER2+ breast cancer.

An expert panel, consisting of the College of American Pathologists, American Society for Clinical Pathology, and the American Society of Clinical Oncology&nbsp;issued comprehensive, evidence-based guidelines for clinicians and pathologists regarding the testing of HER2 status for patients with gastroesophageal adenocarcinoma.&nbsp;

In an interview with <em>Targeted Oncology</em>, Frankie Holmes, MD, discusses HER2-directed therapy with trastuzumab (Herceptin) and pertuzumab (Perjeta).

New findings from a study suggest it is unlikely that any single gene can predict response to targeted therapy for patients with HER2-positive breast cancer. Instead, gene networks&mdash; specifically those involving PI3 kinase &mdash;may provide a clearer picture of patient outcomes.

Though some clinicians may characterize the treatment landscape of HER2-positive breast cancer as overcrowded, Mark Pegram, MD, firmly believes that there is still much to learn in this space.

According to phase I data presented at the 2016 ESMO Congress, a&nbsp;novel HER2-targeting antibody-drug conjugate showed promising antitumor activity across multiple tumor types, including HER2-postive breast cancer.

Chau Dang, MD, medical oncologist, chief, West Harrison Medical Oncology Service, Memorial Sloan Kettering Cancer Center, discusses the future of HER2+ breast cancer treatment.
