Risk Stratification According to Baseline and Early Change in Neutrophil-to-Lymphocyte Ratio in Advanced Non-Small Cell Lung Cancer Treated with Chemoimmunotherapy: A Multicenter Real-World Study.

Background: Chemoimmunotherapy is a standard treatment for advanced non-small-cell lung cancer (NSCLC). However, data on clinical predictive factors remain scarce.

Objective: We aim to identify clinical biomarkers in patients undergoing chemoimmunotherapy.

Brain-derived endothelial cells are neuroprotective in a chronic cerebral hypoperfusion mouse model.

Whether organ-specific regeneration is induced by organ-specific endothelial cells (ECs) remains unelucidated. The formation of white matter lesions due to chronic cerebral hypoperfusion causes cognitive decline, depression, motor dysfunction, and even acute ischemic stroke. Vascular ECs are an important target for treating chronic cerebral hypoperfusion.

Real-world outcomes of nivolumab plus ipilimumab and pembrolizumab with platinum-based chemotherapy in advanced non-small cell lung cancer: a multicenter retrospective comparative study.

Introduction: Nivolumab plus ipilimumab with chemotherapy (NICT) and pembrolizumab with chemotherapy (PCT) are commonly used in patients with advanced non-small cell lung cancer (NSCLC). Compared with immune checkpoint inhibitor (ICI) monotherapy, ICI combination therapy can increase immune-related toxicity instead of prolonging survival. This study aimed to compare the efficacy and safety of NICT and PCT to decide on the favorable treatment.

Sequencing strategies with ramucirumab and docetaxel following prior treatments for advanced non-small cell lung cancer: a multicenter retrospective cohort study.

Objectives: Ramucirumab (RAM) and docetaxel (DOC) are commonly used after first-line therapy for advanced non-small cell lung cancer (NSCLC). Therefore, we aimed to elucidate sequencing strategies of RAM and DOC following prior treatments, including immune checkpoint inhibitor (ICI), cytotoxic agent (CTx) alone, bevacizumab (BEV), and tyrosine kinase inhibitor (TKI).

Methods: We recruited patients with NSCLC who received RAM and DOC and compared the groups with and without prior ICI, CTx alone, BEV, and TKI, respectively.

Secondary subcutaneous abscess due to mixed infections by and after COVID-19.

This report described a rare case of subcutaneous anaerobic bacterial abscess due to and after COVID-19. The patient received incision and drainage of the abscess and antibiotics, thereby achieving recovery. Immunodeficiency related to COVID-19 and its treatment might contribute to secondary skin and subcutaneous bacterial infections.

Impact of treatment line on risks and benefits of immune checkpoint inhibitor in patients with advanced non-small cell lung cancer and interstitial lung disease: a systematic review and meta-analysis of cohort studies.

Background: There is no clear consensus regarding the safety and efficacy of immune checkpoint inhibitors (ICIs) in patients with advanced non-small cell lung cancer (NSCLC) and pre-existing interstitial lung disease (ILD). We aimed to elucidate the impact of ICIs on pre-existing ILD.

Methods: We systematically queried PubMed-MEDLINE, Embase-Scopus, and ISI Web of Science databases up to January 10, 2022.

Respiratory Impedance is Associated with Ventilation and Diffusing Capacity in Patients with Idiopathic Pulmonary Fibrosis Combined with Emphysema.

Purpose: Pulmonary fibrosis and emphysema result in relatively maintained ventilation and reduced diffusing capacity. This pulmonary functional impairment complicates the evaluation of pulmonary function in patients with combined pulmonary fibrosis and emphysema (CPFE). Therefore, a single and easy-to-use pulmonary function index to evaluate patients with CPFE warrants further studies.

A case of synchronous triple autoimmune disorders secondary to thymoma: Pure red cell aplasia, Good's syndrome, and thymoma-associated multi-organ autoimmunity.

Pure red cell aplasia (PRCA), Good's syndrome (GS), and thymoma-associated multiorgan autoimmunity (TAMA) are associated with thymoma. Herein, we describe the case of a 56-year-old woman with PRCA, GS, and TAMA simultaneously. She was treated with cyclosporine, immunoglobulin supplementation, and prednisolone; however, she died of uncontrolled sepsis due to extreme immunosuppression.

Case report: Acute exacerbation of interstitial pneumonia related to messenger RNA COVID-19 vaccination.

Messenger RNA (mRNA) vaccines that protect against COVID-19 are widely used in many countries owing to their high efficacy and safety profiles. Recently, few severe adverse events, such as anaphylaxis and myocarditis, were reported in healthy individuals. The safety of mRNA COVID-19 vaccines has not been adequately studied in patients with interstitial lung disease.

Management of severe hypertension due to lenvatinib in patients with advanced thymic carcinoma: A case report.

Rationale: Thymic carcinoma (TC) is a malignant mediastinal tumor, and there are no established treatments for pre-treated patients with advanced TC. Recently, lenvatinib was approved for such patients in Japan, ahead of other countries. Higher dose lenvatinib may be more efficacious than conventional treatments, although many patients experience grade 3 hypertension.

Efficacy and safety of ramucirumab and docetaxel in previously treated patients with squamous cell lung cancer: a multicenter retrospective cohort study.

Objective: Ramucirumab plus docetaxel (RAM/DOC) therapy is currently the standard for previously treated advanced non-small cell lung cancer (NSCLC), irrespective of histology. However, in the clinical trial, only the first-line platinum-based chemotherapy refractory patients were enrolled and the eligible criteria was strict to avoid hemoptysis, especially in squamous cell NSCLC (Sq). Thus, the efficacy and safety data on ramucirumab for Sq in real-world settings after immune checkpoint inhibitors monotherapy or combination therapy approved as novel first-line therapy is lacking.

Impact of treatment timing and sequence of immune checkpoint inhibitors and anti-angiogenic agents for advanced non-small cell lung cancer: A systematic review and meta-analysis.

Objective: Several studies have demonstrated that anti-angiogenic agents (AAs) have the ability to regulate immune-related cells in the tumor microenvironment and may affect the clinical effect of immune checkpoint inhibitors (ICIs). Therefore, we investigated the drug interaction between ICI and AA for advanced non-small cell lung cancer (NSCLC).

Materials And Methods: We systematically searched PubMed-MEDLINE, Embase-Scopus, and ISI Web of Science before August 23, 2021.

Prolonged corticosteroid therapy and cytomegalovirus infection in patients with severe COVID-19.

Systemic corticosteroid therapy is frequently used to treat coronavirus disease 2019 (COVID-19). However, its maximum duration without secondary infections remains unclear. We aimed to evaluate the utility of monitoring cytomegalovirus (CMV) infection in patients with COVID-19 and estimate the maximum duration of systemic corticosteroid therapy without secondary infections.

Efficacy and safety of ramucirumab plus docetaxel in older patients with advanced non-small cell lung cancer: A multicenter retrospective cohort study.

Objective: Ramucirumab (RAM) plus Docetaxel (DOC) is one of the standard treatments after first-line treatment failure in patients with advanced non-small cell lung cancer (NSCLC). However, little is known about the efficacy and safety of RAM plus DOC in older patients. We aimed to clarify these and elucidate the prognostic factors.

Opposite response of lung adenocarcinoma and its choroidal metastases upon ramucirumab plus docetaxel therapy after immunotherapy: a case report.

We report a unique case of advanced non-small cell lung cancer that exhibited the opposite response to its unilateral choroidal metastases upon ramucirumab plus docetaxel treatment. A combination of cisplatin, pemetrexed, and pembrolizumab was administered as first-line treatment, resulting in shrinkage of all the lesions. However, although the patient was continued on a course of pembrolizumab, all the lesions had recurred approximately two months later.

Impact of docetaxel plus ramucirumab on metastatic site in previously treated patients with non-small cell lung cancer: a multicenter retrospective study.

Background: Docetaxel (DOC) plus ramucirumab (RAM) has been recommended as an optimal therapy for previously treated patients with non-small cell lung cancer (NSCLC). In a clinical setting, there are few reports about DOC plus RAM, therefore its effect on factors such as Eastern Cooperative Oncology Group (ECOG) performance status (PS) and metastatic sites is still unknown.

Methods: We recruited NSCLC patients who received DOC plus RAM in four medical facilities in Japan from June 2016 to March 2020.

Mediastinal undifferentiated pleomorphic sarcoma with pleural effusion cytopathologically misdiagnosed as epithelial malignant pleural mesothelioma: An autopsy case report.

Undifferentiated pleomorphic sarcoma (UPS) is a new disease in the World Health Organization's classification of tumors of soft tissue and bone published in 2013. Primary mediastinal UPS is rare, especially with pleural effusion. Herein, we describe the pathological findings of pleural effusion followed by mediastinal UPS, which was initially misdiagnosed as epithelial malignant pleural mesothelioma (MPM).

Lymphoplasmacytic lymphoma involving the mediastinum and the lung, followed by amyloidosis: A surgically and genetically proven case.

A 60-year-old man was admitted for ground glass opacity in the lower lung field and mediastinal lymphadenopathy. Blood tests revealed elevated serum IgM levels, and the urine test detected Bence-Jones protein. Surgical biopsy from the mediastinal lymph node and lung showed small lymphocytes and plasma cells between follicles, and AL kappa amyloid deposition.

Nivolumab treatment beyond progressive disease in advanced non-small cell lung cancer.

Purpose: This study evaluated the efficacy and safety of nivolumab treatment beyond progressive disease (PD) in non-small cell lung cancer (NSCLC).

Patients/methods: Medical records of consecutive patients with advanced NSCLC who received nivolumab between December 2015 and December 2018 were reviewed. Clinical outcomes of three groups of eligible patients who received nivolumab as a second-line treatment after PD were compared based on Response Evaluation Criteria in Solid Tumors v1.
