Randomized Controlled Trial
The minimal clinically important difference of the Richmond Agitation-Sedation Scale in patients with cancer with agitated delirium.
The Richmond Agitation-Sedation Scale (RASS) is commonly used to assess psychomotor activity; however, to the authors' knowledge, its minimal clinically important difference (MCID) has not been determined to date. The objective of the current study was to identify the MCID for RASS using 2 anchor-based approaches. ⋯ For patients with persistent restlessness/agitation, a reduction of ≥4 points in RASS was considered to be the MCID for both nurses and caregivers. These preliminary findings may have implications for sample size calculation and the interpretation of treatment effect in future delirium trials.

Multiple myeloma (MM) is the second most common hematologic malignancy and represents approximately 10% of all hematological neoplasms. Standard therapy consists of induction therapy followed by high-dose chemotherapy and autologous stem cell transplantation (ASCT) or, if ASCT cannot be performed, standard doublet, triplet, or quadruplet, novel agent-containing induction treatment until progression. Although MM is still regarded as mostly incurable by current standards, the development of several novel compounds, combination therapies, and immunotherapy approaches has raised great hopes about transforming MM into an indolent, chronic disease and possibly achieving a cure for individual patients. ⋯ Especially in the field of immunotherapy, including monoclonal antibodies, checkpoint inhibition, and chimeric antigen receptor T cells, current advances are rapid and highly promising. This review aims to summarize the newest and most promising immunotherapeutic agents for MM, their clinical efficacy, their adverse event (AE) profiles, and the ways in which these AEs can best be overcome or avoided.

Advances in cancer immunotherapy and a growing body of research have focused on the role of the antitumor response in breast cancer. Triple-negative breast cancer (TNBC) is the most immunogenic breast cancer subtype, and there is strong evidence that tumor-infiltrating lymphocytes in TNBC have prognostic value and are associated with clinical outcome and improved survival. Evading antitumor immunity is a hallmark for the development and progression of cancer. ⋯ Blockade of the PD-1/PD-L1 axis has emerged as a promising therapeutic option to enhance antitumor immunity and is actively being investigated in TNBC, with encouraging results. In this article, the authors review the current literature on checkpoint inhibitors in TNBC with a focus on PD-1/PD-L1 antibodies and discuss combination strategies and novel approaches for improving antitumor immunity and clinical outcome.

The current study compares the results of irradiation with protons and irradiation with carbon ions via a raster scan technique in patients with G1 and G2 skull base chondrosarcomas. ⋯ No significant difference between carbon ions and protons in the therapy of skull base chondrosarcoma could be detected in these initial retrospective results.

Human epidermal growth factor receptor 2 (HER2)-targeted therapies are highly effective at preventing breast cancer recurrence but are associated with cardiotoxicity in some patients, and minimal data are available regarding racial disparities in the incidence of this toxicity. The authors conducted a retrospective study to analyze the association of black or white race with treatment-induced cardiotoxicity and incomplete therapy among patients with HER2-positive early breast cancer. ⋯ Black patients have a higher rate of cardiotoxicity and resultant incomplete adjuvant HER2-targeted therapy than white patients. This patient population may benefit from enhanced cardiac surveillance, cardioprotective strategies, and early referral to cardiology when appropriate.
