Importance The development of immune checkpoint inhibitors targeting cytotoxic T-lymphocyte antigen 4 (CTLA-4) and programmed cell death-1 (PD-1) has significantly improved the treatment of a variety of cancers and led to US Food and Drug Administration approvals for patients with a variety of malignant neoplasms. Immune checkpoint inhibitors enhance(More)
Laboratory studies suggest that vitamin D (vitD) enhances chemotherapy-induced cell death. The objective of this study was to determine whether pretreatment vitD levels were associated with response to neoadjuvant chemotherapy (NACT) in women with breast cancer. Study patients (n = 82) were enrolled on the I-SPY TRIAL, had HER2-negative tumors, and(More)
T cell checkpoint blockade therapies are revolutionizing the treatment of patients with cancer. Highlighted by the recent success of PD-1 plus CTLA-4 blockade in patients with melanomas, synergistic immunotherapy combinations of modalities represent an important opportunity to improve responses and outcomes for patients. We review the rationale and(More)
The immune system plays an essential role in the surveillance and eradication of neoplastic cells. This interaction is modulated via immunologic regulators (checkpoints). Antibodies that block the checkpoints cytotoxic T lymphocyte-associated antigen 4 (CTLA-4), and the programmed cell death protein 1 pathway (PD1/PD-L1) have demonstrated efficacy in a(More)
PURPOSE Breast cancer survivors (BCS) taking aromatase inhibitors (AIs) are at an increased risk for decreased bone density and fractures. Given the role vitamin D plays in bone metabolism, we examined the prevalence of and risk factors for vitamin D deficiency in a study of postmenopausal BCS on AIs. METHODS We collected data on 391 postmenopausal women(More)
The pioneers of tumor immunology and cancer immunotherapy, including the late William B. Coley and Lloyd J. Old, have championed the potential for immunotherapy for over a century. Finally, advances in our understanding of the fundamentals of tumor immunology are translating into clinical success, with recent US Food and Drug Administration approval of(More)
The Common Terminology Criteria for Adverse Events (CTCAE) were developed to document the adverse effects of chemotherapy but are now also used to document immune-related adverse events (irAE). Characterization of irAE by the CTCAE has implications for determining dose-limiting toxicity (DLT) and, consequently, the recommended phase II dose (RP2D) of(More)
The incidence of melanoma and associated mortality rate from advanced disease in older adults is increasing over time. Checkpoint inhibitors have demonstrated a survival benefit for the treatment of stage IV or unresectable stage III disease and have become one of the standards of care. Data suggests that adults aged 65 and older benefit from treatment with(More)
