Phase 1/2 trial of XPO1 inhibitor selinexor plus docetaxel in previously treated, advanced KRAS mutant non-small cell lung cancer.

Purpose: Patients with KRAS mutant non-small cell lung cancer (NSCLC) have limited therapeutic options. Based on activity of nuclear export inhibition in preclinical models, we evaluated this strategy in previously treated advanced KRAS mutant NSCLC.

Patients And Methods: The primary outcome of this multi-center phase 1/2 dose escalation trial of selinexor plus docetaxel was safety and tolerability.

The Emerging Role of Immune Checkpoint Blockade for the Treatment of Lung Cancer Brain Metastases.

Lung cancer has the highest incidence of brain metastases (BM) among solid organ cancers. Traditionally whole brain radiation therapy has been utilized for non-small-cell lung cancer (NSCLC) BM treatment, although stereotactic radiosurgery has emerged as the superior treatment modality for most patients. Highly penetrant central nervous system (CNS) tyrosine kinase inhibitors have also shown significant CNS activity in patients harboring select oncogenic drivers.

A Phase II Trial of the WEE1 Inhibitor Adavosertib in SETD2-Altered Advanced Solid Tumor Malignancies (NCI 10170).

Unlabelled: We sought to evaluate the efficacy of WEE1 inhibitor adavosertib in patients with solid tumor malignancies (cohort A) and clear cell renal cell carcinoma (ccRCC; cohort B). NCT03284385 was a parallel cohort, Simon two-stage, phase II study of adavosertib (300 mg QDAY by mouth on days 1-5 and 8-12 of each 21-day cycle) in patients with solid tumor malignancies harboring a pathogenic SETD2 mutation. The primary endpoint was the objective response rate.

Model-driven decision support: A community-based meta-implementation strategy to predict population impact.

Purpose: Standard tools for public health decision making such as data dashboards, trial repositories, and intervention briefs may be necessary but insufficient for guiding community leaders in optimizing local public health strategy. Predictive modeling decision support tools may be the missing link that allows community level decision makers to confidently direct funding and other resources to interventions and implementation strategies that will improve upon the status quo.

Methods: We describe a community-based model-driven decision support (MDDS) approach that requires community engagement, local data, and predictive modeling tools (agent-based modeling in our case studies) to improve decision-making on implementing strategies to address complex public health problems such as overdose deaths.

A Path to Persistence after EGFR Inhibition.

Residual cancer cells persist even after targeted therapies, serving as a reservoir for the subsequent acquisition of genetic alterations that lead to acquired drug resistance and tumor relapse. These initial drug-tolerant persisters (DTP) are phenotypically heterogenous with transient phenotypes attributed to epigenetic, metabolic, and cell-cycle changes. DTPs are responsible for the inevitable relapse seen in EGFR-mutant non-small cell lung cancer (NSCLC) despite high initial response to tyrosine kinase inhibitor (TKI) treatment.

TWIST1 is a critical downstream target of the HGF/MET pathway and is required for MET driven acquired resistance in oncogene driven lung cancer.

MET amplification/mutations are important targetable oncogenic drivers in NSCLC, however, acquired resistance is inevitable and the majority of patients with targetable MET alterations fail to respond to MET tyrosine kinase inhibitors (TKIs). Furthermore, MET amplification is among the most common mediators of TKI resistance. As such, novel therapies to target MET pathway and overcome MET TKI resistance are clearly needed.

p90RSK pathway inhibition synergizes with cisplatin in TMEM16A overexpressing head and neck cancer.

Head and neck squamous cell carcinoma (HNSCC) constitutes one of the most common types of human cancers and often metastasizes to lymph nodes. Platinum-based chemotherapeutic drugs are commonly used for treatment of a wide range of cancers, including HNSCC. Its mode of action relies on its ability to impede DNA repair mechanisms, inducing apoptosis in cancer cells.

Lorlatinib and capmatinib in a ROS1-rearranged NSCLC with MET-driven resistance: tumor response and evolution.

Acquired drug resistance remains a major problem across oncogene-addicted cancers. Elucidation of mechanisms of resistance can inform rational treatment strategies for patients relapsing on targeted therapies while offering insights into tumor evolution. Here, we report acquired MET amplification as a resistance driver in a ROS1-rearranged lung adenocarcinoma after sequential treatment with ROS1 inhibitors.

Male sex and pretreatment weight loss are associated with poor outcome in patients with advanced non-small cell lung cancer treated with immunotherapy: a retrospective study.

The influence of sex and body mass index (BMI) on the efficacy of immune checkpoint inhibitors (ICIs) in advanced non-small cell lung cancer (NSCLC) patients remains unclear. We conducted a retrospective study to evaluate the relationship between sex, BMI, pretreatment weight loss (PWL), and clinical outcomes in 399 stage IV NSCLC patients treated with ICIs using data abstracted from medical records. Multivariable Cox proportional hazards models were used to assess the impact on overall survival and progression-free survival.

Device evaluation: eCoin #x2013; implantable tibial nerve stimulator for overactive bladder.

Introduction: Peripheral nerve stimulation has been demonstrated as a viable alternative to sacral nerve stimulation in managing refractory overactive bladder (OAB). New technologies allow the internalization of tibial nerve stimulators through various apparatuses. One such device, the eCoin, is a small, coin-shaped device that can be implanted adjacent to the tibial nerve that provides pre-programmed stimulation.

COVID-19 Testing Among Out-of-Hospital Cardiac Arrest Patients: Implications for Public Health.

Objective: The objective of this study was to compare COVID-19 test positivity among out-of-hospital cardiac arrest patients whose resuscitative efforts were terminated in the field with the surrounding community.

Methods: This was a retrospective cohort study of out-of-hospital cardiac arrest patients for whom unsuccessful resuscitative efforts were terminated in the field. Emergency medical services (EMS) personnel obtained postmortem COVID-19 nasal swab specimens from these patients between July 1, 2020 and February 28, 2022 to facilitate patient contact tracing and awareness of potential occupational exposure.

Phase II Study of Docetaxel and Trametinib in Patients with KRAS Mutation Positive Recurrent Non-Small Cell Lung Cancer (NSCLC; SWOG S1507, NCT-02642042).

Purpose: Efficacy of MEK inhibitors in KRAS+ NSCLC may differ based on specific KRAS mutations and comutations. Our hypothesis was that docetaxel and trametinib would improve activity in KRAS+ NSCLC and specifically in KRAS G12C NSCLC.

Patients And Methods: S1507 is a single-arm phase II study assessing the response rate (RR) with docetaxel plus trametinib in recurrent KRAS+ NSCLC and secondarily in the G12C subset.

Targeting the epidermal growth factor receptor following complete surgical resection in patients with early-stage non-small cell lung cancer.

Introduction: Activating mutations in the () gene are one of the most common targetable oncogenic drivers of non-small cell lung cancer (NSCLC). Osimertinib is a third-generation EGFR tyrosine kinase inhibitor (EGFR-TKI) that selectively inhibits EGFR-TKI sensitizing ( or ) and mutations and has superior CNS penetration. Osimertinib is approved in mutant stage IB-IIIA NSCLC following complete tumor resection.

How I Do It: Transperineal prostate biopsy using local anesthetic in an outpatient setting.

Transperineal prostate biopsy (TPPB) is proven to be an effective diagnostic tool for prostate cancer detection. It allows satisfactory sampling of apical and anterior areas which is not well achieved with the transrectal route, without the associated risks of urinary tract infection or sepsis. The main objective of this paper is to describe the technique utilized in our institution to perform transperineal prostate biopsy under local anesthetic in the outpatient clinic setting.

An EMS Transport Destination Officer is Associated with Reductions in Simultaneous Emergency Department Arrivals.

A centralized transport destination officer (TDO) is one technique used by EMS systems to distribute patients. This retrospective analysis examines the effect of a TDO on simultaneous arrivals and consecutive simultaneous arrivals at emergency departments in a suburban EMS system, and their relationship to transport unit throughput. Each system hospital arrival from July 1, 2020 to February 28, 2022, at six study hospitals was evaluated.

Introduction: This Phase 1/2 study (NCT02349633) explored the safety and antitumor activity of PF-06747775 (oral, third-generation epidermal growth factor receptor [EGFR] tyrosine kinase inhibitor) in patients with advanced non-small cell lung cancer after progression on an EGFR inhibitor.

Methods: Phase 1 was a dose-escalation study of PF-06747775 monotherapy (starting dose: 25 mg once daily [QD]). Phase 1b/2 evaluated PF-06747775 monotherapy at recommended Phase 2 dose (RP2D; Cohort 1); PF-06747775 200 mg QD plus palbociclib (starting dose: 100 mg QD orally; Cohort 2A); and PF-06747775 monotherapy at RP2D in a Japanese lead-in cohort.

Clinicopathologic and Genomic Landscape of Non-Small Cell Lung Cancer Brain Metastases.

Background: In patients with non-small cell lung cancer (NSCLC), 10%-40% will eventually develop brain metastases. We present the clinicopathologic, genomic, and biomarker landscape of a large cohort of NSCLC brain metastases (NSCLC-BM) samples.

Materials And Methods: We retrospectively analyzed 3035 NSCLC-BM tested with comprehensive genomic profiling (CGP) during routine clinical care.

Decreases in out of hospital cardiac arrest (OHCA) outcome metrics persist when known COVID patients are excluded from analysis.

Objective: A decline in OHCA performance metrics during the pandemic has been reported in the literature but the cause is still not known. The Montgomery County Fire and Rescue Service (MCFRS) observed a decline in both the rate of return of spontaneous circulation (ROSC) and the proportion of resuscitations that resulted in cerebral performance category (CPC) 1 or 2 discharge of the patient beginning in March of 2020. This study examines whether the decline in these performance metrics persists when known COVID positive patients are excluded from the analysis.

UBA1 and DNMT3A mutations in VEXAS syndrome. A case report and literature review.

Vacuoles, E1 enzyme, X linked, autoinflammatory, somatic (VEXAS) syndrome is a recently described X-linked autoinflammatory condition associated with somatic mutation of the ubiquitin-like modifier activating enzyme 1 (UBA1) gene. It often coexists with myelodysplastic syndrome, which can occur due to DNA (cytosine-5)-methyltransferase 3A (DNMT3A) mutation. These patients, predominantly males, present after the fifth decade of life with unique systemic inflammatory clinical features and have haematological abnormalities and vacuolated precursor cells on bone marrow pathology.
