The American Society of Clinical Oncology (ASCO) meeting of 2016 is behind us, but oncologists, patients, and journalists are still analyzing the most interesting presentations made there. Below, we describe some of the more prominent results in triple negative breast cancer (TNBC), both promising and disappointing.
“IMMU-132, an anti-Trop-2 antibody-drug conjugate (ADC) was safe, tolerable, and yielded meaningful clinical activity in heavily pretreated patients with metastatic triple-negative breast cancer (TNBC), according to data from a phase II clinical trial presented at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics, held Nov. 5–9.
” ‘TNBC comprises about 15 to 20 percent of all invasive breast cancers diagnosed in the United States and is more prevalent in young and African-American women. It has a high recurrence rate and is perhaps the most difficult type of breast cancer to treat successfully with current cytotoxic agents. Currently, there are no targeted treatments available for TNBC,’ said Aditya Bardia, MD, MPH, assistant professor of medicine at Harvard Medical School, and attending physician of medical oncology at the Massachusetts General Hospital Cancer Center in Boston.”
“The molecular mechanisms underlying metastatic dissemination are still not completely understood. We have recently shown that β1 integrin-dependent cell adhesion to fibronectin (FN) and signaling are affected by a transmembrane molecule, Trop-2, which is frequently upregulated in human carcinomas. Here we report that Trop-2 promotes metastatic dissemination of prostate cancer cells in vivo and is abundantly expressed in metastasis from human prostate cancer…”
