Background: Although chemoimmunotherapy is recommended for advanced nonsquamous non-small cell lung cancer (NSCLC) with low programmed cell death ligand 1 (PD-L1) expression, no head-to-head comparisons of immune checkpoint inhibitors (ICIs) have been performed. Therefore, we compared the effect and safety of regimens in these patients to guide evidence-based treatment.

Methods: This retrospective study included patients with advanced nonsquamous NSCLC with a PD-L1 tumor proportion score of 1% to 49% administered ICI combination platinum-based chemotherapy between May 2018 and May 2023 at 19 institutions in Japan.

The original concept of the airway-to-lung size mismatch, termed dysanapsis, was introduced on spirometry and was extended by computed tomography (CT) evaluation of the central airways. CT-assessed dysanapsis allows a risk estimation of lung disease development in healthy subjects, although radiation exposure limits its use, particularly for younger subjects. This study investigated which spirometry indices can be used to estimate CT-assessed central airway dysanapsis in healthy subjects.

Purpose: Rearranged during transfection (RET) aberrations represent a targetable oncogene in several tumor types, with RET inhibitors displaying marked efficacy. However, some patients with RET-aberrant cancer are insensitive to RET tyrosine kinase inhibitors (TKIs). Recently, drug-tolerant mechanisms have attracted attention as targets for initial therapies to overcome drug resistance.

Article Synopsis
  • The study investigated the role of thyroid transcription factor 1 (TTF-1) as a predictor for treatment response in advanced non-squamous non-small-cell lung cancer (NSCLC) patients undergoing chemotherapy or chemoimmunotherapy with specific levels of PD-L1 expression.
  • Out of 624 patients surveyed, 283 met the criteria, revealing that TTF-1 positivity was associated with significantly longer progression-free survival (PFS) and overall survival (OS) in those receiving chemotherapy, but not in the chemoimmunotherapy group.
  • The findings suggest that TTF-1 expression can help predict treatment effectiveness for chemotherapy, while its impact on chemoimmunotherapy remains unclear in patients with PD-L1 levels between

Immune-mediated necrotizing myopathy (IMNM), an inflammatory muscle disease, typically presents as severe muscle weakness due to immunologic mechanisms. Some cases also show cutaneous manifestations, interstitial lung disease, and sicca symptoms. In this report, we present a unique case of an elderly man with a history of mild and stable Sjögren's syndrome (SS) for over 10 years, who later developed interstitial lung disease and myositis, leading to a diagnosis of IMNM confirmed by the presence of anti-signal recognition particle antibodies.

Although many researchers have devoted their much effort to establish the strategy for developing a stimuli-responsive molecule and tuning of their properties according to the preprogrammed design, it is still challenging to create desired molecules from the scratch. We recently demonstrated that the molecules with a large structural difference between the theoretically optimized structures in the ground and excited states have a potential to exhibit stimuli-responsive luminescent properties. We defined these molecules as an excitation-driven molecule and have shown that they are a versatile platform for designing stimuli-responsive luminescent molecules.

Introduction: Several studies explored the association between thyroid transcription factor-1 (TTF-1) and the therapeutic efficacy of immunotherapy. However, the effect of TTF-1 on the therapeutic efficacy of programmed death-1 (PD-1) inhibitor/chemoimmunotherapy in patients with non-squamous non-small cell lung cancer (non-Sq NSCLC) with a programmed death-ligand 1 (PD-L1) tumor proportion score of 50% or more who are highly susceptible to immunotherapy remains unresolved. Therefore, we evaluated whether TTF-1 has a clinical impact on this population.

Heavy atoms can form highly coordinated states, and their optical properties have attracted much attention. Recently, we have demonstrated that a reversible coordination-number shift of hypervalent tin(IV) from five to six can provide predictable hypsochromic shifts in light absorption and emission properties in small molecules and a π-conjugated polymer film. Herein, we show the preparation of seven-coordinated tin and reveal that the binding constant of the seven coordination with ethylenediamine (EDA, = 2900 M) is 200 times higher than that of six coordination with propylamine (PA, = 14 M) owing to the chelate effect.

  • Second-line immune checkpoint inhibitor (ICI) therapy in non-small cell lung cancer (NSCLC) patients with ≤ 49% PD-L1 expression has limited effectiveness, and there is a need to understand predictors of its efficacy after platinum-based chemotherapy.
  • A study involving 54 advanced NSCLC patients in Japan found that those who did not experience disease progression after first-line chemotherapy had significantly better response rates and overall survival when treated with ICI monotherapy compared to those who had disease progression.
  • Maintaining a non-progressive disease status after chemotherapy emerged as a key independent prognostic factor for better outcomes with ICI therapy, along with a trend suggesting that a modified Glasgow Prognostic Score of 0 could correlate with longer survival.

Background: Effective use of lung volume data measured on computed tomography (CT) requires reference values for specific populations. This study examined whether an equation previously generated for multiple ethnic groups in the United States, including Asians predominantly composed of Chinese people, in the Multi-Ethnic Study of Atherosclerosis (MESA) could be used for Japanese people and, if necessary, to optimize this equation. Moreover, the equation was used to characterize patients with chronic obstructive pulmonary disease (COPD) and lung hyperexpansion.
