Simple prediction tools for disease progression in unvaccinated patients with mild/moderate COVID-19 aged under 65 years: Simplified DOATS and DOAT scores.

DOATS score and DOAT score, COVID-19 progression prediction tools we have developed, utilize clinical information such as presence of diabetes/obesity (DO), age (A), body temperature (T), and oxygen saturation (S). They showed good predictive power, but their scoring calculation was slightly complex, leading us to develop simplified versions. This report discusses the ability of the simplified versions to assess deterioration risk in unvaccinated, mild/moderate COVID-19 patients aged <65 years.

Pretreatment glasgow prognostic score predicts survival among patients administered first-line atezolizumab plus carboplatin and etoposide for small cell lung cancer.

Background: There are no established predictive biomarkers for the effectiveness of first-line atezolizumab plus carboplatin and etoposide therapy in patients with small-cell lung cancer (SCLC). Therefore, the current study aimed to investigate whether the Glasgow prognostic score (GPS), neutrophil-to-lymphocyte ratio (NLR), and body mass index (BMI) can predict the effectiveness of first-line atezolizumab plus carboplatin and etoposide therapy in patients with extensive-disease SCLC.

Methods: We reviewed data from 84 patients who received first-line atezolizumab plus carboplatin and etoposide therapy for SCLC at nine Japanese institutions between August 2019 and May 2021.

Post-progression survival after atezolizumab plus carboplatin and etoposide as first-line chemotherapy in small cell lung cancer has a significant impact on overall survival.

Background: The effect of first-line chemotherapy on overall survival (OS) may be significantly influenced by subsequent therapy for patients with extensive disease small cell lung cancer (ED-SCLC). Therefore, we evaluated the relationship between progression-free survival (PFS), post-progression survival (PPS), and OS of ED-SCLC patients treated with atezolizumab plus carboplatin and etoposide as first-line therapy.

Methods: We analyzed the data of 57 patients with relapsed ED-SCLC treated with atezolizumab plus carboplatin and etoposide (AteCE) as first-line chemotherapy between August 2019 and September 2020.

This retrospective study evaluated patients with relapsed SCLC who were treated with previously AteCE combination therapy followed by amrubicin monotherapy between August 2019 and May 2021. Clinical efficacy and toxicity were analyzed.

Development of dermatomyositis after anti-transcriptional intermediary factor 1-γ antibody seroconversion during treatment for small cell lung cancer.

Background: Inflammatory myositis, such as dermatomyositis, is sometimes complicated by cancer and is recognized as cancer-associated myositis. Although some autoimmune antibodies are considered to be involved in the development of myositis in cancer patients, the precise mechanism has not been clarified. The findings of the present case shed light on the mechanism by which anti-transcriptional intermediary factor 1 (TIF1)-γ Ab was produced and the pathogenesis of cancer-associated myositis.

Clinical Outcomes of Postoperative Adjuvant Chemotherapy for Surgically Resected High-Grade Pulmonary Neuroendocrine Carcinoma.

Introduction: Data on the clinical outcomes of patients receiving adjuvant chemotherapy for surgically resected high-grade pulmonary neuroendocrine carcinoma (HGNEC) (large-cell neuroendocrine carcinoma and small-cell lung cancer) are limited. This study aimed to evaluate the prognostic significance of adjuvant chemotherapy in patients with HGNEC.

Methods: We retrospectively analyzed patients with surgically resected HGNEC at five institutions in Japan between January 2006 and May 2016.

Effectiveness and Safety of EGFR-TKI Rechallenge Treatment in Elderly Patients with Advanced Non-Small-Cell Lung Cancer Harboring Drug-Sensitive EGFR Mutations.

: Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are effective first-line chemotherapeutic agents for patients with advanced non-small-cell lung cancer (NSCLC) harboring drug-sensitive mutations. However, the effectiveness of EGFR-TKI rechallenge after first-line EGFR-TKI treatment is not sufficient in elderly patients (over 75 years of age) harboring drug-sensitive mutations. Therefore, we investigated the effectiveness and safety of EGFR-TKI rechallenge after first-line EGFR-TKI treatment in elderly patients with advanced NSCLC harboring drug-sensitive mutations.

Usefulness of diurnal variation of fractional exhaled nitric oxide for predicting early therapeutic response to asthma treatment.

Objective: Fractional exhaled nitric oxide (FeNO) is considered to be an adjunct for asthma management, although its usefulness remains controversial. Therefore, it may be necessary for new approaches to use FeNO for asthma management. We evaluated whether diurnal variations of FeNO can predict response to asthma treatment.

Pretreatment Glasgow prognostic score predicts survival among patients with high PD-L1 expression administered first-line pembrolizumab monotherapy for non-small cell lung cancer.

Background: There are no established biomarkers for predicting the efficacy of first-line pembrolizumab monotherapy in patients with high programmed death-ligand 1 (PD-L1) expression. In this study, we investigated whether the Glasgow prognostic score (GPS), neutrophil-to-lymphocyte ratio (NLR), and body mass index (BMI) can be used to evaluate the effect of first-line pembrolizumab monotherapy in patients with advanced non-small cell lung cancer (NSCLC) who express high levels of PD-L1.

Methods: We reviewed data from 142 patients with high PD-L1 expression who underwent first-line pembrolizumab monotherapy for NSCLC at six Japanese institutions between February 2017 and June 2019 and assessed the prognostic value of the GPS, NLR, and BMI.

Post-Progression Survival Influences Overall Survival among Patients with Advanced Non-Small Cell Lung Cancer Undergoing First-Line Pembrolizumab Monotherapy.

Background: Among patients with non-small cell lung cancer (NSCLC), the impact of first-line treatment on overall survival (OS) may be influenced by subsequent therapies. Thus, using patient-level data, we assessed the relationships of progression-free survival (PFS) and post-progression survival (PPS) with OS among patients with high-programmed death-ligand 1 (PD-L1) expression undergoing first-line pembrolizumab monotherapy for NSCLC.

Methods: We reviewed data from 133 patients with high PD-L1 expression undergoing first-line pembrolizumab monotherapy for NSCLC at 6 Japanese centers between February 2017 and December 2018.

Association Between Sleep Characteristics and Asthma Control in Middle-Aged and Older Adults: A Prospective Cohort Study.

Background: Nocturnal asthma symptoms are a well-known feature of sleep disturbance. However, there are few reports on the association between sleep-related characteristics and asthma exacerbation. The aim of the current prospective observational study was to explore the factors while sleeping associated with future asthma exacerbation.

Randomized phase II trial of carboplatin + nab-paclitaxel versus cisplatin + gemcitabine for chemotherapy-naïve squamous cell carcinoma: North Japan lung cancer study group 1302.

Background: A subset analysis of the CA031 trial showed significant improvement in the overall response rate after administration of carboplatin plus weekly albumin-bound paclitaxel compared to carboplatin plus paclitaxel for squamous cell carcinoma of the lung (SQ). We conducted this phase II study to compare carboplatin plus weekly albumin-bound paclitaxel (CnP) to cisplatin plus gemcitabine (CG), a standard regimen for SQ.

Methods: Chemotherapy-naïve patients with SQ were randomly assigned to receive cisplatin (80 mg/m) on day 1 plus gemcitabine (1000 mg/m) on days 1 and 8 every 3 weeks or carboplatin (area under the curve: 6 mg/mL/min) on day 1 plus nab-paclitaxel (75 mg/m) on days 1, 8, and 15 every 3 weeks.

Prognostic value of morphological characteristics assessed by CT scan in patients with non-small cell lung cancer treated with nivolumab.

Background: Nivolumab is known to demonstrate superior overall survival compared with docetaxel in pretreated non-small cell lung cancer (NSCLC) patients. Programmed death-ligand 1 (PD-L1) expression is reported to predict the outcome of treatment by nivolumab in lung cancer patients. However, the significance of the morphological characteristics of chest computed tomography (CT) as predictors of nivolumab efficacy for advanced NSCLC patients remains unknown.

Efficacy and safety of S-1 monotherapy in previously treated elderly patients (aged ≥75 years) with non-small cell lung cancer: A retrospective analysis.

Background: S-1 monotherapy is effective and feasible for previously treated patients with advanced non-small cell lung cancer (NSCLC). However, it is not clear whether its effectiveness and tolerability in elderly patients are equivalent to those in younger patients. Hence, this study aimed to evaluate the efficacy and feasibility of S-1 monotherapy in elderly patients with NSCLC who had previously received other treatments.

Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) is a primary intestinal T-cell lymphoma and other organ involvement is very rare. A rare case of MEITL involving the lung and brain is herein reported. The patient developed panperitonitis with a small intestinal perforation, and emergency surgery was performed.

Clinical significance of thyroid hormone and antibodies in patients with idiopathic interstitial pneumonia.

Background: Hypothyroidism was recently reported to be common and to predict mortality in patients with idiopathic pulmonary fibrosis (IPF). In addition, a high prevalence of hypothyroidism was shown in patients with idiopathic pleuroparenchymal fibroelastosis. However, in idiopathic interstitial pneumonia (IIP), a clinical significance of thyroid function has not been clarified in detail.

Efficacy and safety of immune checkpoint inhibitor monotherapy in pretreated elderly patients with non-small cell lung cancer.

Purpose: Immune checkpoint inhibitors (ICIs) are an effective subsequent-line treatment for patients with advanced non-small cell lung cancer (NSCLC). However, it remains unclear whether the efficacy and safety of subsequent-line ICI monotherapy in elderly patients (aged ≥ 75 years) are similar to that in non-elderly patients. Therefore, we aimed to investigate the efficacy and safety of ICI monotherapy in pretreated elderly patients with NSCLC.
