Jane Lowe Meisel, MD, reviewed systemic therapy options for treating patients with breast cancer with a group of physicians during a&nbsp;<em>Targeted Oncology&nbsp;</em>live case-based peer perspectives discussion. Meisel explained the treatment considerations she makes for treating patients with breast cancer during the dinner event in terms of 2 case studies.

The SOLAR-1 findings were presented during a satellite symposium at the 2019 European Society for Medical Oncology Breast Cancer Annual Congress in Berlin, Germany.&nbsp;The trial demonstrated the role of&nbsp;<em>PIK3CA&nbsp;</em>as a predictive marker for alpelisib&rsquo;s clinical efficacy, said Peter A. Fasching, MD, associate professor of gynecology and obstetrics at Friedrich-Alexander University of Erlangen-Nuremberg in Germany, during the symposium.

Preventive strategies for severe diarrhea associated with adjuvant treatment with neratinib improved tolerability for the agent when patients received budesonide or colestipol-with-loperamide prophylaxis, according to findings from the CONTROL study.

Biomarker expansion has enjoyed a boom since 2006, with patient incidence of positive biomarkers reaching up to 50% in non&ndash;small cell lung cancer and melanoma and 25% in acute myeloid leukemia and myelodysplastic syndromes, according&nbsp; to the <em>Global Oncology Trends 2018</em> report.

Patients with HER2-positive metastatic breast cancer receiving frontline HER2-targeted therapy with pertuzumab&nbsp;and trastuzumab followed by T-DM1 in the second-line setting may be able to forgo chemotherapy without increasing the risk of early death, according to results from the phase II PERNETTA trial.

Debu Tripathy, MD, of the Department of Breast Medical Oncology, Division of Cancer Medicine, MD Anderson Cancer Center, was an investigator in the phase III MONALEESA-7 trial. The purpose of the study was to examine how endocrine therapy, in combination with a cyclin-dependent kinase inhibitor, affects progression-free survival and overall survival in premenopausal patients with HR-positive, HER2-negative advanced breast cancer.

A supplemental New Drug Application has been submitted to the FDA for the potential approval of neratinib in combination with capecitabine for the treatment of patients with HER2-positive metastatic breast cancer who have progressed on 2 or more prior HER2-targeted treatments.

In June 2019, the FDA approved a number of agents many fields, including diffuse large B-cell lymphoma, head and neck squamous cell carcinoma, small cell lung cancer, gastroenteropancreatic neuroendocrine tumors, and multiple myeloma. The FDA also approved the fifth biosimilar for trastuzumab and another biosimilar for&nbsp;bevacizumab across several indications.

During a recent <em>Targeted Oncology </em>case-based peer perspectives live dinner event, Massimo Cristofanilli, MD, explained the options for treatment based on the case scenario of a woman with ER-positive breast cancer.<br /> &nbsp;

Susan Friedman, executive director and founder, FORCE, a non-profit organization supporting education, advocacy, and research around breast and ovarian cancer, explains the relevance of PARP inhibitors and the recent developments in oncology research that may improve cancer treatment for patients with genetic mutations.

The American Cancer Society, Dana-Farber Cancer Institute, Baptist Cancer Center, and the Mayo Clinic report&nbsp;that treatment patterns varied markedly by cancer type and care facility setting for patients with de novo metastatic disease who died within 1 month after diagnosis, based on an analysis of data from 100,848 patients collected from the National Cancer Database, a hospital-based cancer registry that captures 70% of patients in the United States with a new diagnosis.

The FDA recently released 5 new draft guidance documents that promote broader patient eligibility for cancer clinical trials. The policies encourage inclusion of certain individuals who were previously disqualified due to medical conditions or biological factors, including brain metastases, organ dysfunction, prior or concurrent malignancies, chronic infections, and age.
