Background And Objectives: Due to heterogeneous characteristics of primary cancers, the efficacy of pulmonary metastasectomy (PM) in nonprimary lung cancers has not been investigated. This study aims to investigate the clinical outcomes of PM for non-primary lung cancer.
Methods: A systematic search for meta-analyses on PM for nonprimary lung cancers was conducted, encompassing publications up to January 3, 2024.

Background: Anti-programmed death-1 (PD-1)/cytotoxic T lymphocyte antigen-4 antibodies are efficacious in various malignancies.
Objectives: This study presents the first results of ipilimumab-nivolumab in invasive mucinous or non-mucinous lepidic adenocarcinoma (invasive mucinous adenocarcinoma (IMA) or invasive non-mucinous lepidic adenocarcinomas (INLA), respectively) of the lung.
Design: Dual anti-CTLA-4 and anti-PD-1 blockade in rare tumors (DART) is a prospective, open-label, multicenter (1016 US sites), multi-cohort phase II trial of ipilimumab (1 mg/kg intravenously (IV) every 6 weeks) plus nivolumab (240 mg IV every 2 weeks).
Background: Invasive mucinous adenocarcinoma (IMA) is a rare histological subtype of lung invasive adenocarcinoma with unique clinical, radiological, histopathological, and genomic characteristics. There have been limited studies on the effectiveness of systemic therapy for lung IMA, with conflicting results reported.
Methods: We retrospectively investigated the medical records of patients diagnosed with lung IMA.
Introduction: Immune checkpoint inhibitors (ICIs) may be associated with hyperprogressive disease (HPD). However, there is currently no standardized definition of HPD, with its risk factors and clinical implications remaining unclear. We investigated HPD in lung cancer patients undergoing immunotherapy, aiming to redefine HPD, identify risk factors, and assess its impact on survival.

In this study, we explored the utility of ctDNA-based MRD detection to predict recurrence in a real-world cohort of primarily early-stage non-small cell lung cancer (NSCLC) patients treated with curative intent.
Methods: Longitudinal plasma samples were collected post curative-intent treatment from 36 patients with stage I-IV NSCLC.
Treating advanced thyroid cancer presents challenges due to its resistance to various treatment modalities, thereby limiting therapeutic options. To our knowledge, this study is the first to report the efficacy of temsirolimus in conjunction with dual immunotherapy of nivolumab/ipilimumab to treat heavily treated advanced PDTC. A 50-year-old female initially presented with a rapidly enlarging mass on her right neck.

Activins, members of the TGF-beta superfamily, have been isolated and identified in the endocrine system, but have not been substantially investigated in the context of the immune system and endocrine-unrelated cancers. Here, we demonstrated that tumor-bearing mice had elevated systemic activin levels, which correlated directly with tumor burden. Likewise, cancer patients have elevated plasma activin levels compared to healthy controls.

MATERIAL AND METHODS Data from all cases reported in the literature were pooled for analysis and additional data were collected from the Organ Procurement Transplantation Network (OPTN) registry. Recurrence-free survival (RFS), overall survival (OS), and cancer-specific survival (CSS) of patients who underwent DLT for lung cancer were determined.

We investigated the incidence and types of PTM and its impact on survival following double lung transplantation (DLT). The incidence and type of PTM as well as the annual and cumulative risks of each malignancy after DLT were analyzed.

However, according to the International Society for Heart and Lung Transplantation, lung cancer constituted a mere 0.1% of the indications for lung transplantation over the past two decades.

However, the role of CD4+ T cells in promoting LTS fibrosis is unknown. The mTOR signaling pathways have been shown to regulate the T cell phenotype.

Although there is great interest in harnessing this cytokine as a therapeutic in natural or engineered formats, the clinical potential of native IL-4 is limited by its instability and pleiotropic actions. Here, we design IL-4 cytokine mimetics (denoted Neo-4) based on a de novo engineered IL-2 mimetic scaffold and demonstrate that these cytokines can recapitulate physiological functions of IL-4 in cellular and animal models.

We developed a regenerative immunotherapy from the helminth soluble egg antigen (SEA) to stimulate production of interleukin (IL)-4 and other type 2-associated cytokines without negative infection-related sequelae. The regenerative SEA (rSEA) applied to a murine muscle injury induced accumulation of IL-4-expressing T helper cells, eosinophils, and regulatory T cells and decreased expression of IL-17A in gamma delta (γδ) T cells, resulting in improved repair and decreased fibrosis.

However, there are several limitations to autologous cell therapy, including low availability, poor quality of starting cellular material and limited expansion capability. Recently, induced pluripotent stem cell (iPSC)-derived allogeneic cell therapy platforms have gained popularity, as they seek to overcome many of the challenges inherent to current autologous cell therapies.

It can be used, for example, to determine the parts of the system that when influenced by outside controlling signals, can ultimately steer the behavior of the entire network. One of the challenges in utilizing the ideas from network controllability on real systems is that there is typically more than one potential solution (often many) suggested by the topology of the graph that perform equally well.

Here, we applied micro- and ultrafine porcine urinary bladder matrix (UBM) particulate to promote type 2 immune responses in cornea wounds. Results demonstrated that UBM particulate substantially reduced corneal haze formation as compared to the saline-treated group.

Colorectal cancers with activating mutations in are associated with distinct clinical characteristics, although the pathogenesis is not well understood. The Wnt-driven multiple intestinal neoplasia (Min) enterotoxigenic (ETBF) murine model is characterized by IL17-dependent, distal colon adenomas.

We hypothesize that broadly active glutamine antagonist, DON will reduce collagen formation and fibrosis-associated gene expression in iLTS mice.

Senescent cells (SnCs) are implicated in the pathogenesis of age-related diseases including osteoarthritis (OA), in part via expression of a senescence-associated secretory phenotype (SASP) that includes immunologically relevant factors and cytokines. In a model of posttraumatic OA (PTOA), anterior cruciate ligament transection (ACLT) induced a type 17 immune response in the articular compartment and draining inguinal lymph nodes (LNs) that paralleled expression of the senescence marker p16INK4a (Cdkn2a) and p21 (Cdkn1a). Innate lymphoid cells, γδ+ T cells, and CD4+ T cells contributed to IL-17 expression.

Several studies have shown that YAP is upregulated in cancer cells, and more recently in the T regulatory (Treg) subset of CD4+ cells. These observations suggest that the transcriptional co-activator may promote tumor persistence and progression.

To explore the immune and stromal connections underpinning the foreign body response, we analyzed fibrotic capsules surrounding surgically excised human breast implants from 12 individuals. We found increased numbers of interleukin 17 (IL17)-producing γδ T cells and CD4 T helper 17 (T17) cells as well as senescent stromal cells in the fibrotic capsules.
