Adjuvant therapy for renal cell carcinoma, finally a new standard?

Localized renal cell carcinoma (RCC) has the potential to be cured with surgery alone; however, some patients have a high risk of relapse and may benefit from additional treatment. Several efforts have been made to identify effective strategies, with mostly negative results. However, recent results with immune checkpoint inhibitors may change the current standard, and several ongoing trials are exploring new alternatives. In this perspective, we aim to provide an overview of previous adjuvant therapy efforts, current data supporting the use of checkpoint blockade, and a future outlook for adjuvant therapy in renal cell carcinoma.

Remote research on locomotion interfaces for virtual reality: Replication of a lab-based study on teleporting interfaces.

The wide availability of consumer-oriented virtual reality (VR) equipment has enabled researchers to recruit existing VR owners to participate remotely using their own equipment. Yet, there are many differences between lab environments and home environments, as well as differences between participant samples recruited for lab studies and remote studies. This paper replicates a lab-based experiment on VR locomotion interfaces using a remote sample. Participants completed a triangle-completion task (travel two path legs, then point to the path origin) using their own VR equipment in a remote, unsupervised setting. Locomotion was accomplished using two versions of the teleporting interface varying in availability of rotational self-motion cues. The size of the traveled path and the size of the surrounding virtual environment were also manipulated. Results from remote participants largely mirrored lab results, with overall better performance when rotational self-motion cues were available. Some differences also occurred, including a tendency for remote participants to rely less on nearby landmarks, perhaps due to increased competence with using the teleporting interface to update self-location. This replication study provides insight for VR researchers on aspects of lab studies that may or may not replicate remotely.

Neoadjuvant immunotherapy for muscle invasive urothelial bladder carcinoma: will it change current standards?

Immunotherapy, in the form of immune checkpoint inhibitors (ICI), has shown activity in metastatic urothelial bladder carcinoma, resulting in the approval of several ICI agents in the first- and second-line settings. This has led to an increased interest in studying their efficacy in the neoadjuvant setting for muscle invasive disease - an area of significant unmet need. This non-systematic review will look at the evidence supporting the use of ICI in the neoadjuvant setting for this tumor, results of early-phase studies, ongoing trials, and possible future applications for these drugs.

Primary Adrenal Insufficiency during Immune Checkpoint Inhibitor Treatment: Case Reports and Review of the Literature.

As the indications and clinical use of immune checkpoint inhibitors increase, it is expected that we will face some of their less frequently reported complications. Primary adrenal insufficiency is one of them, and given its unspecific symptoms and potentially serious consequences, it is important to have a high degree of clinical suspicion. We present 3 cases and a review of the literature concerning its main clinical characteristics, diagnostics, and management.

Immune Checkpoint Inhibitor Dosing: Can We Go Lower Without Compromising Clinical Efficacy?

In just a few years, immune checkpoint inhibitors have dramatically changed the landscape in oncology, offering durable responses and improved survival for many patients across several tumor types. With more than 3,300 new agents in the immuno-oncology pipeline plus a wide array of combinations being studied, it seems this new era is just getting started. These advances come with a significant caveat: most of the world population does not have access to their benefits, because the yearly cost of a novel anticancer medication can routinely exceed $100,000. There is a large amount of data showing that checkpoint inhibitors have significant activity at doses much lower than those currently approved. We review the evidence for reduced drug dosing as a strategy to increase the number of patients who can be treated and what would be needed to further validate this approach.

Is Cytoreductive Nephrectomy Still a Standard of Care in Metastatic Renal Cell Carcinoma?

Cytoreductive nephrectomy has been an integral part of management in metastatic renal cell carcinoma for patients with good performance status, based on the benefit shown by prospective trials in the interferon era and retrospective trials in the targeted therapies era. Clinical Trial to Assess the Importance of Nephrectomy (CARMENA), the first prospective phase III trial comparing a targeted agent alone (sunitinib) versus nephrectomy plus sunitinib, has been recently published, showing non-inferiority for the nephrectomy-sparing arm. In this article, we discuss the impact of nephrectomy including its immune-mediated effects, surgical morbidity and mortality, and the clinical data supporting the indications of nephrectomy in order to analyze the CARMENA trial in context, with the aim to identify optimal strategies for different patient populations in the metastatic setting.
