Subjective symptoms are triggers for the detection of immune checkpoint inhibitor-induced interstitial lung disease and associate with disease severity: a single-center retrospective study.

Background: Interstitial lung disease (ILD) is one of the most common fatal immune-related adverse events (irAEs). ILD development adversely affects the continuation of anticancer drug therapy, including immune checkpoint inhibitor (ICI) therapy and prognosis. There are no established useful clinical indicators for the early detection of ILD.

Performance status improvement and advances in systemic treatment after brain metastases resection: a retrospective single-center cohort study of non-small cell lung cancer patients.

Background: Brain metastasis (BrM) is prevalent among patients with NSCLC, and surgical resection of BrM constitutes a promising treatment strategy for local management and histopathological diagnosis, although it is offered for a select group of patients. Limited information exists concerning the improvement in performance status (PS) following BrM resection or the outcomes stratified by subsequent systemic therapy.

Methods: We conducted a retrospective single-center cohort study including NSCLC patients with surgically resected BrM and focused on the improvement in PS and subsequent therapy after BrM resection.

Successful treatment of lung cancer coexisting with B‑cell lymphoma with pembrolizumab following rituximab‑included chemotherapy: A case report.

The combined occurrence of lung cancer and B-cell lymphoma, such as mucosa-associated lymphoid tissue (MALT) lymphoma, is rare. The efficacy and safety of immune checkpoint inhibitors (ICIs) remain unknown in this population of patients, and the occurrence of ICI-induced exacerbation of lymphoma is concerning. The present study describes a case of successful treatment with pembrolizumab following rituximab-containing chemotherapy for lung cancer complicated by MALT lymphoma.

Connective tissue growth factor enhances TGF-β1-induced osteogenic differentiation via activation of p38 MAPK in mesenchymal stem cells.

Objectives: Cellular differentiation is based on the effects of various growth factors. Transforming growth factor (TGF)-β1 plays a pivotal role in inducing osteogenic differentiation of mesenchymal stem cells (MSCs). In this study, we investigated the influence of connective tissue growth factor (CTGF), known to function synergistically with TGF-β1, on osteogenic differentiation in MSCs.

polymorphism for predicting nivolumab benefit in patients with advanced non‑small‑cell lung cancer.

Immune checkpoint inhibitors (ICIs), such as nivolumab, play an essential role in non-small-cell lung cancer (NSCLC) treatment. Programmed death ligand-1 has been used as a predictive biomarker for the efficacy of ICI treatment in patients with NSCLC; however, its predictive value is considered insufficient. Therefore, there is an urgent need for better predictive biomarkers.

Outcomes of immune checkpoint inhibitors for postoperative recurrence of non-small cell lung cancer.

Objectives: Immune checkpoint inhibitors (ICIs) are effective treatment options for patients with advanced non-small cell lung cancer (NSCLC); however, there is a dearth of data on outcomes of patients receiving ICIs for postoperative recurrence. The objective of this study was to investigate the short- and long-term outcomes of patients who received ICIs for postoperative recurrence.

Methods: A retrospective chart review was performed to identify consecutive patients who received ICIs for postoperative recurrence of NSCLC.

Sarcomatoid malignant pleural mesothelioma treated with nivolumab: A case series.

Immune checkpoint therapy (ICT) with nivolumab has been widely used to treat malignant pleural mesothelioma (MPM) since clinical trials confirmed its efficacy. However, only a few clinical trials have been conducted for the treatment of sarcomatoid MPM, which is a rare histological type of MPM. Additionally, clinical reports of sarcomatoid MPM are scarce.

Usefulness of pro-gastrin-releasing peptide as a predictor of the incidence of brain metastasis and effect of prophylactic cranial irradiation in patients with limited-stage small-cell lung cancer.

Prophylactic cranial irradiation (PCI) is recommended for patients with limited-stage small-cell lung cancer (LS-SCLC) who respond well to initial treatment. However, PCI is often omitted because of its potential neurotoxicity in the era of modern diagnostic imaging devices. In the present study, we aimed to investigate the risk factors for brain metastasis (BM) in patients eligible for PCI and who may benefit more from it.

How to Manage the Cortex After CTR Insertion.

Capsular tension ring (CTR) realizes safe cataract surgery. However, residual cortex removal becomes difficult with CTR. Originally, the flushing technique was developed for intracameral antibiotic administration.

Hydro-dispersion of subincisional cortex.

Background: A simple technique to facilitate removal of subincisional cortex in cataract surgery is presented.

Methods: A disposable 27-gauge blunt needle attached to a 5.0-ml syringe containing balanced salt solution (BSS) is introduced through the side port incision into the anterior chamber.

Survival impact of treatment for chronic obstructive pulmonary disease in patients with advanced non-small-cell lung cancer.

Chronic obstructive pulmonary disease (COPD) may coexist with lung cancer, but the impact on prognosis is uncertain. Moreover, it is unclear whether pharmacological treatment for COPD improves the patient's prognosis. We retrospectively investigated patients with advanced non-small-cell lung cancer (NSCLC) who had received chemotherapy at Kyoto University Hospital.

Relapsing polychondritis after treatment with PD-1 blockade.

Nivolumab, a programmed death 1 blockade drug, is used in various types of cancers and can cause a unique immune-related adverse event (irAE). Relapsing polychondritis (RP) is a rare autoimmune disease that mainly involves inflammation of the auricle, nose and airway cartilage. A 72-year-old man with mandibular cancer received nivolumab after surgery for the primary lesion and radiation therapy for lung metastases.

The role of comprehensive analysis with circulating tumor DNA in advanced non-small cell lung cancer patients considered for osimertinib treatment.

Background: EGFR mutations are good predictive markers of efficacy of EGFR tyrosine kinase inhibitors (EGFR-TKI), but whether comprehensive genomic analysis beyond EGFR itself with circulating tumor DNA (ctDNA) adds further predictive or prognostic value has not been clarified.

Methods: Patients with NSCLC who progressed after treatment with EGFR-TKI, and with EGFR T790 M detected by an approved companion diagnostic test (cobas ), were treated with osimertinib. Plasma samples were collected before and after treatment.

Abundant oleoyl-lysophosphatidylethanolamine in brain stimulates neurite outgrowth and protects against glutamate toxicity in cultured cortical neurons.

Lysophosphatidylethanolamines (LPEs) are bioactive lysophospholipids that have been suggested to play important roles in several biological processes. We performed a quantitative analysis of LPE species and showed their composition in mouse brain. We examined the roles of oleoyl-LPE (18:1 LPE), which is one of the abundant LPE species in brain.

PD-L1 polymorphisms predict survival outcomes in advanced non-small-cell lung cancer patients treated with PD-1 blockade.

Background: We previously reported that PD-L1 polymorphisms are associated with the efficacy and immune-related adverse events of PD-1 blockade with nivolumab. However, the association between PD-L1 polymorphisms and survival outcomes under PD-1/PD-L1 blockade is still uncertain. Here, we aimed to investigate whether PD-L1 polymorphisms are associated with survival outcomes in advanced non-small-cell lung cancer (NSCLC) patients treated with nivolumab.

Structurally different lysophosphatidylethanolamine species stimulate neurite outgrowth in cultured cortical neurons via distinct G-protein-coupled receptors and signaling cascades.

Neurite outgrowth is important in neuronal circuit formation and functions, and for regeneration of neuronal networks following trauma and disease in the brain. Thus, identification and characterization of the molecules that regulate neurite outgrowth are essential for understanding how brain circuits form and function and for the development of treatment of neurological disorders. In this study, we found that structurally different lysophosphatidylethanolamine (LPE) species, palmitoyl-LPE (16:0 LPE) and stearoyl-LPE (18:0 LPE), stimulate neurite growth in cultured cortical neurons.

A Randomized Phase II Study of Maintenance Bevacizumab, Pemetrexed or Bevacizumab Plus Pemetrexed for Advanced Non-squamous Non-small Cell Lung Cancer.

Background/aim: Continuation maintenance therapy is standard for advanced nonsquamous non-small cell lung cancer; however, the optimal maintenance strategy has yet to be determined.

Patients And Methods: Patients without disease progression after four cycles of carboplatin (CBDCA)+ pemetrexed (PEM)+ bevacizumab (BEV) were randomized to maintenance therapy with BEV, PEM, or BEV+PEM. The primary endpoint was 1-year progression-free survival (PFS) rate.

Management and Outcomes of Newly Diagnosed Non-Small Cell Lung Cancer Patients with Brain Metastases: A Real-World Study in Japan.

Background: Brain metastases (BM) are one of the strongest negative prognostic factors in patients with non-small cell lung cancer (NSCLC). Molecularly targeted agents are standard of care for NSCLC patients with a driver mutation; however, their efficacy in patients with BM is not fully understood because patients with BM are usually excluded from clinical studies. This study investigated the current management and outcomes of newly diagnosed NSCLC patients with BM in Japanese clinical practice, focusing on their driver mutation status.

Acquired Resistance to Alectinib in ALK-Rearranged Lung Cancer due to ABCC11/MRP8 Overexpression in a Clinically Paired Resistance Model.

Alectinib is used as a first-line treatment for anaplastic lymphoma kinase (ALK)-rearranged non-small cell lung cancer (NSCLC). Whereas other ALK inhibitors have been reported to be involved in resistance to ATP-binding cassette (ABC) transporters, no data are available regarding the association between resistance to alectinib and ABC-transporters. To investigate whether ABC-transporters contribute to alectinib resistance, ABC-transporter expression in alectinib-resistant cell lines derived from a patient with ALK-rearranged NSCLC and from H2228 lung cancer cells was evaluated and compared with that in each parent cell type.
