Unlabelled: Patients who have radiographically detectable lesions in their brain or other symptoms compatible with brain tumors pose challenges for diagnosis. The only definitive way to diagnose such patients is through brain biopsy, an obviously invasive and dangerous procedure. Here we present a new workflow termed "CSF-BAM" that simultaneously identifies cell or T cell receptor rearrangements, neuploidy, and using PCR-mediated amplification of both strands of the DNA from CSF samples.

This study examined the impact of s-irAEs and their earliest management strategies on clinical outcomes in advanced non-small cell lung cancer (NSCLC).
Methods: Data were derived from ConcertAI Patient360 NSCLC, a US-based electronic medical record database, between January 2012 and May 2021.
Background: The association between safety and efficacy of immune checkpoint inhibitors is known, but the correlation between severity and impact of specific organ involvement by immune-related adverse events (irAE) and cancer outcomes is poorly understood. Most irAEs are mild-to-moderate but severe irAEs may pose clinical management challenges and affect patient outcomes.
Methods: We assessed the association between irAE grade (G) and specific organ involvement with overall survival (OS) in 9,521 patients across 14 studies involving atezolizumab as mono (IO) or with chemo/targeted (C-IO) therapy as compared with chemo/targeted therapy (C) in advanced non-small cell lung, small-cell lung, renal cell, urothelial, and triple-negative breast cancers.
Human induced pluripotent stem cell-derived models are a well-established preclinical tool, with the ability to retain the genetics of the individual from which they are derived. Here we comment on the global representation and accessibility of such cellular tools from African population groups.

Osimertinib and alectinib, both TKIs, have shown significant improvements in outcomes for patients with resected - and -positive NSCLC, respectively, changing the standard of care in these subgroups. More recently, the LAURA trial showed the efficacy of osimertinib after chemoradiotherapy in patients with unresectable stage III NSCLC harboring mutations.

HiPSCs could be transformative in regenerative and precision medicine, therefore, the generation of diverse lines is critical in the establishment of African-relevant preclinical cellular models. HiPSC lines were derived from two healthy donors of Black African ancestry using Sendai virus reprogramming of dermal fibroblasts, and characterised to confirm stemness markers, trilineage differentiation, and genetic integrity.

We performed a systematic review and meta-analysis of the toxicity of combination treatment of ICIs with TKIs (ICI + TKI) in clinical trials with solid organ malignancies. Our primary endpoint explored the incidence of grade 3 - 5 (G3-5) treatment-related toxicity and our secondary endpoints included the incidence of toxicity by treatment type, disease type and studies with run-in strategies.

Methods: Retrospective series of patients with immune-related encephalitis and literature review.
Concurrent chemoradiotherapy (cCRT) followed by one year of consolidation durvalumab is the current standard-of-care for patients with unresectable stage III non-small cell lung cancer (NSCLC), of good functional status. However, cCRT and consolidation durvalumab may be challenging to administer for selected patient populations underrepresented or even excluded in clinical trials: older and/or frail patients; those with cardiovascular or respiratory comorbidities in which treatment-related adverse events may be higher, and patients with pre-existing autoimmune disorders for whom immunotherapy use is controversial. In this narrative review, we discuss the current evidence, challenges, ongoing clinical trials and potential future treatment scenarios in relevant subgroups of patients with locally advanced NSCLC, who are underrepresented in clinical trials.

Their utility to answer questions surrounding immune-related adverse events (irAEs), common and potentially dangerous toxicities from cancer immunotherapy, are not well defined.
Methods: We developed 50 distinct questions with answers in available guidelines surrounding 10 irAE categories and queried two AI chatbots (ChatGPT and Bard), along with an additional 20 patient-specific scenarios.
Chemoimmunotherapy is currently the preferred first-line treatment option for the majority of patients with advanced non-small cell lung cancer without driver genetic alterations. Most of these patients, however, will experience disease progression within the first year after treatment initiation and both patients and their physicians will be confronted with the dilemma of the optimal second-line treatment. Identification of molecular targets, such as , , , and human epidermal growth factor receptor 2 mutations, and RET rearrangements offer therapeutic opportunities in pretreated patients with corresponding alterations.

Hypertension is characterised by elevated blood pressure (BP) ≥ 140/90 mmHg. Current hypertension guidelines recommend the use of antihypertensives belonging to the following classes: calcium channel blockers (CCB), angiotensin converting inhibitors (ACEI), angiotensin receptor blockers (ARB), diuretics, -blockers, and mineralocorticoid receptor antagonists (MRAs), to manage hypertension.
View Article and Find Full Text PDFWith an increasing number of patients eligible for immune checkpoint inhibitors, the incidence of immune-related adverse events (irAEs) is on the rise. Dermatologic immune-related adverse events (D-irAEs) are the most common and earliest to manifest, often with important downstream consequences for the patient. Current guidelines lack clarity in terms of diagnostic criteria for D-irAEs.
View Article and Find Full Text PDFOver the past 20 years, there has been a paradigm shift in the care of patients with non-small cell lung cancer (NSCLC), who now have a range of systemic treatment options including targeted therapy, chemotherapy, immunotherapy (ICI), and antibody-drug conjugates (ADCs). A proportion of these cancers have single identifiable alterations in oncogenes that drive their proliferation and cancer progression, known as "oncogene-addiction". These "driver alterations" are identified in approximately two thirds of patients with lung adenocarcinomas, via next generation sequencing or other orthogonal tests.

This retrospective study aims to identify the proportion of patients with advanced NSCLC in the Republic of Ireland whose tumors harbor actionable genomic alterations through broad NGS panel testing.
Methods: Institutional review board approval was obtained before study initiation.
Lack of equitable representation of global genetic diversity has hampered the implementation of genomic medicine in under-represented populations, including those on the African continent. Data from the multi-national Pre-emptive Pharmacogenomic Testing for Preventing Adverse Drug Reactions (PREPARE) study suggest that genotype guidance for prescriptions reduced the incidence of clinically relevant adverse drug reactions (ADRs) by 30%. In this study, hospital dispensary trends from a tertiary South African (SA) hospital (Steve Biko Academic Hospital; SBAH) were compared with the drugs monitored in the PREPARE study.
View Article and Find Full Text PDFImmune checkpoint inhibitor (ICI) treatment has become an important therapeutic option for various cancer types. Although the treatment is effective, ICI can overstimulate the patient's immune system, leading to potentially severe immune-related adverse events (irAEs), including hepatitis, colitis, pneumonitis and myocarditis. The initial mainstay of treatments includes the administration of corticosteroids.

Here, we describe pneumococcal disease hospitalizations at Ministry of Health (MoH) facilities in Malaysia between 2013 and 2015.
Methods: This was a retrospective databases analysis.
Immune checkpoint inhibitors have become standard-of-care for the treatment of NSCLC; however, their use brings with it the risk of a unique set of inflammatory side effects, termed immune-related adverse events (irAEs). The recognition, diagnosis, and management of irAEs have become essential to clinical practice, with the potential for high-grade toxicities affecting treatment decision-making. This manuscript provides a state-of-the-art review of irAEs as they pertain to patients with NSCLC, by summarizing the common and severe toxicities of the standard immune checkpoint inhibitor regimens and clinical treatment settings relevant to this disease and future directions.
