Which AEs are most common with immunotherapy? Most concerning? Are some patients more likely to experience AEs? Should immunotherapy be used for patients with a pre-existing autoimmune condition? Do AEs predict response? Moffitt’s Dr. Hatem Soliman addresses these and other questions in this interview.

A literature review involving 24 recent studies yielded an update to ASCO’s recommendations on appropriate use of breast cancer biomarker assay results to guide adjuvant endocrine and chemotherapy decisions in early-stage breast cancer.

The NR2F1 gene normally prevents pre-malignant cells from spreading to other parts of the body. HER2 suppresses NR2F1, allowing pre-cancerous cells to move to other organs where they can become cancerous.

The phase 2 trial of giredestrant in breast cancer patients whose disease has progressed, failed to show benefit.

“For patients with T1cN1-2 or T2-4N0 (stage II or III), early-stage TNBC, the Panel recommends use of pembrolizumab (200 mg once every 3 weeks or 400 mg once every 6 weeks) in combination with neoadjuvant chemotherapy, followed by adjuvant pembrolizumab after surgery.”

According to the final results from the phase 3 PALLAS trial, palbociclib offers no benefit over endocrine therapy alone in women with early HR+ HER2- breast cancer. The primary endpoint — 4-year invasive DFS — was nearly equivalent in the test and control arms of the study. None of the secondary endpoints showed a significant difference either. There was a high rate of palbociclib discontinuation (42%), mostly due to grade 3 or 4 neutropenia. But even in those who completed the two-year planned course showed no benefit over endocrine therapy alone. The results were not just disappointing, but surprising given that CDK 4/6 inhibitors plus endocrine therapy is the standard of care for advanced breast cancer.
