Assessing the effect of metastasis-directed therapy in oligometastatic disease using the restricted mean survival time.

Background: Metastasis-directed therapy (MDT) with stereotactic body radiotherapy (SBRT) is emerging as an effective therapeutic option for oligometastatic disease (OMD). However, a lack of phase III data, consensus guidelines, and toxicity concerns limit its widespread use. Randomized controlled trials (RCTs) routinely report hazard ratios (HRs) and medians that lack clear clinical and robust interpretation.

Converging survival trends in non-small cell lung cancer patients with and without brain metastasis receiving state-of-the-art treatment.

Introduction: Historically, patients with brain metastasis (BM) have been excluded from clinical trials investigating treatments for non-small cell lung cancer (NSCLC) due to their unfavorable prognosis. Advanced treatments have increased survival prospects for NSCLC patients with BM. This study evaluated the life expectancy of NSCLC patients with and without BM in the context of contemporary treatments.

mutations detected by tumour next-generation sequencing in non-small cell lung cancer: impact on response to therapy and disease course.

Background: Data regarding the prevalence and clinical relevance of mutations in non-small cell lung cancer (NSCLC) is limited. Our objective was to evaluate the impact of pathogenic variants detected by tumour next-generation sequencing (NGS) on disease course and response to therapy.

Methods: We performed a retrospective analysis of all consecutive NSCLC patients with available NGS reports in a single institution between 01/2015 and 08/2020.

Correlations between pathogenic variants in DNA repair genes and anticancer treatment efficacy in stage IV non-small cell lung cancer: A large real-world cohort and review of the literature.

Background: Mutations in genes involved in DNA damage repair (DDR), a hallmark of cancer, are associated with increased cancer cell sensitivity to certain therapies. This study sought to evaluate the association of DDR pathogenic variants with treatment efficacy in patients with advanced non-small cell lung cancer (NSCLC).

Methods: A retrospective cohort of consecutive patients with advanced NSCLC attending a tertiary medical center who underwent next-generation sequencing in 01/2015-8/2020 were clustered according to DDR gene status and compared for overall response rate (ORR), progression-free survival (PFS) (patients receiving systemic therapy), local PFS (patients receiving definitive radiotherapy), and overall survival (OS) using log-rank and Cox regression analyses.

Avelumab for the treatment of locally advanced or metastatic Merkel cell carcinoma-A multicenter real-world experience in Israel.

Background: Merkel cell carcinoma (MCC) is a rare and aggressive malignancy of the skin, affecting predominantly the fair-skinned older population exposed to high levels of ultraviolet light. Immune suppression is considered a significant risk factor. With the recent advances in the field of immunotherapy, the treatment paradigm for advanced MCC, traditionally based on chemotherapy, has largely shifted to anti-PD-L1 and PD-1 agents such as avelumab and pembrolizumab, respectively.

First-line programmed death-1 inhibitor treatment for locoregionally advanced or metastatic cutaneous squamous cell carcinoma - A real-world experience from Israel.

Objective: Cutaneous squamous cell carcinoma (cSCC) is the second most common non-melanoma skin cancer worldwide. It is usually treated surgically, with very high cure rates. However, in 3%-7% of cases, cSCC metastasizes to lymph nodes or distant organs.

Venous thromboembolism incidence and risk assessment in lung cancer patients treated with immune checkpoint inhibitors.

Background: There are scarce data on venous thromboembolism (VTE) rates among non-small cell lung cancer (NSCLC) patients treated with immune-checkpoint inhibitors (ICI). The Khorana Score (KS), used to guide thromboprophylaxis in cancer patients, was validated in patients receiving chemotherapy.

Objective: To assess VTE rates and KS performance among NSCLC patients treated with ICI or chemotherapy.

Social-Stress-Responsive Microbiota Induces Stimulation of Self-Reactive Effector T Helper Cells.

Stressful life events are considered a risk factor for autoimmune disorders, though the mechanisms are unclear. Here we demonstrate that chronic social stress induces virulence-associated transcriptional patterns in the murine gut microbiota. The stress-influenced microbiota increased the presence of effector T helper cells in the mesenteric lymph nodes, including myelin-autoreactive cells.
