Background: The aim of this study was to identify poor prognostic factors and explore optimal second-line treatment strategies for patients with epidermal growth factor receptor (EGFR)-mutant nonsmall cell lung cancer (NSCLC) who developed resistance to EGFR tyrosine kinase inhibitors (TKIs).
Patients And Methods: We retrospectively evaluated patients with advanced or recurrent EGFR-mutant NSCLC who received platinum-based systemic therapy after EGFR-TKI failure from January 2017 to July 2022 at 20 institutions. Logistic regression analysis was used to identify factors associated with 1-year mortality after the start of systemic therapy.
Background: In Japan, chemoimmunotherapy was approved as treatment for advanced or recurrent non-small-cell lung cancer (NSCLC), including for patients with epidermal growth factor receptor (EGFR) mutations, in December 2018. However, the impact of its approval on real-world clinical outcomes among patients with EGFR-mutant NSCLC remains unclear. The aim of our study was to assess that impact.

Although ALK tyrosine kinase inhibitors (ALK-TKIs) are effective for treating ALK-positive NSCLC, some patients still show suboptimal responses and poor outcomes. Clinically simple and detectable biomarkers for this group are limited.

However, in some patients, the therapeutic efficacy of osimertinib is suboptimal, leading to heterogeneity in treatment response, which presents a clinical challenge. It remains unclear how the expression level of EGFR-mutant protein affects osimertinib treatment and clinical outcomes.

To identify patients who do not benefit from the addition of immune checkpoint inhibitors (ICI) to chemotherapy, we conducted a retrospective study at 19 institutions in Japan. We analyzed 851 patients with advanced NSCLC with a PD-L1 tumor proportion score of 1% to 49% who received chemoimmunotherapy (n = 504) or chemotherapy (n = 347) between March 2017 and June 2022.

However, older patients remain underrepresented in clinical trials, and optimal treatment strategies for this population remain unclear. This study sought to evaluate the efficacy and safety of first-line treatment with either platinum-based chemotherapy alone (Chemo) or in combination with ICIs (ICI/Chemo) in older patients with NSCLC who have low PD-L1 expression.

Therapeutic strategies that inhibit the mitogen-activated protein kinase pathway, a critical effector pathway in KRAS-mutated cancers, have garnered significant attention. Among several molecular-targeted drugs, avutometinib (CKI27(2)/CH5126766/RO5126766/VS-6766), a novel dual RAF/MEK clamp, shows promise for patients with KRAS-mutated cancers.

However, their effect on clinical outcomes has yet to be fully elucidated. In this study, we investigated the impact of irAEs, particularly pneumonitis, on clinical outcomes in patients receiving combined immunotherapy and chemotherapy for NSCLC.
View Article and Find Full Text PDFBackground: The efficacy of immune checkpoint inhibitor (ICI) monotherapy on non-small-cell lung cancer (NSCLC) varies by epidermal growth factor receptor (EGFR) mutation subtypes. However, the impact of these subtypes on the clinical outcomes of chemoimmunotherapy (Chemo+ICI) or platinum-based chemotherapy (Chemo) in real-world practice remains unclear.
Objective: This study evaluated the impact of EGFR mutation subtypes on NSCLC treatment outcomes of Chemo and Chemo+ICI.
Objectives: In patients with non-small cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) mutations, a chemoimmunotherapy regimen of atezolizumab, bevacizumab, carboplatin, and paclitaxel (ABCP) has shown promising outcomes following treatment with EGFR-tyrosine kinase inhibitors (EGFR-TKIs). However, evidence on whether ABCP provides a survival advantage over platinum-based chemotherapy in real-world clinical settings remains limited. This study aimed to investigate the efficacy and safety of ABCP versus platinum-based chemotherapy in patients with EGFR-mutant NSCLC who underwent EGFR-TKI treatment.

However, it remains unclear whether the FAN score is a prognostic factor for platinum-based first-line chemotherapy. We included 126 patients with mUC who received platinum-based first-line chemotherapy.

However, very few studies have compared the efficacy of these drugs in patients with mRCC, particularly those with bone metastases (BM), which are associated with a poor prognosis. This study compared the efficacy of nivolumab and TKIs as second-line treatments for mRCC patients with BM and examined the microenvironments of primary tumors and BM lesions.

We examined whether patients ineligible for clinical trials may benefit from ICI-Chemo.
Methods: This multicenter retrospective cohort study enrolled patients with aNSCLC, including unresectable Stage III (IIIB/IIIC) and IV disease with a PD-L1 tumor proportion score of 1-49% treated with ICI-Chemo or Chemo as first-line therapy from 2018 to 2023 in Japan.
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.

Background/aim: There is little evidence regarding the predictive value of prostate-specific antigen (PSA) kinetics in patients with castration-resistant prostate cancer treated with an androgen receptor signaling inhibitor. This study investigated the correlation between PSA kinetics and prognosis in patients with castration-resistant prostate cancer treated with enzalutamide.
Patients And Methods: We analyzed data from 103 patients who received enzalutamide as primary treatment for castration-resistant prostate cancer at our hospital, focusing on the associations between overall survival and PSA kinetics variables, such as maximal PSA response, PSA nadir, and time to PSA nadir.

Sarcopenia assessed at a single time point is associated with the efficacy of immunotherapy, and we hypothesized that longitudinal changes in muscle mass may also be important. This retrospective study included patients with non-small cell lung cancer (NSCLC) who received durvalumab treatment after concurrent chemoradiotherapy (CCRT) between January 2017 and April 2023. Muscle loss and sarcopenia were assessed based on the lumbar skeletal muscle area.

The RAF/MEK clamp avutometinib (VS-6766/CH5126766/RO5126766/CKI27) is promising for patients with KRAS-mutated cancers. Although avutometinib monotherapy has shown clinical activity in patients with KRAS-mutated cancers, effective combination strategies will be important to develop.

Saccharomyces cerevisiae is one of the most important microorganisms for the food industry, including Japanese sake, beer, wine, bread, and other products. For sake making, Kyokai sake yeast strains are considered one of the best sake yeast strains because these strains possess fermentation properties that are suitable for the quality of sake required. In recent years, the momentum for the development of unique sake, which is distinct from conventional sake, has grown, and there is now a demand to develop unique sake yeasts that have different sake making properties than Kyokai sake yeast strains.
