PSA Kinetics Affect Prognosis in Patients With Castration-resistant Prostate Cancer Treated With Enzalutamide.

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.

The Significance of Longitudinal Psoas Muscle Loss in Predicting the Maintenance Efficacy of Durvalumab Treatment Following Concurrent Chemoradiotherapy in Patients with Non-Small Cell Lung Cancer: A Retrospective Study.

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.

Cumulative incidence and risk factors for medication-related osteonecrosis of the jaw during long-term prostate cancer management.

Bone-modifying agents (BMA) are extensively used in treating patients with prostate cancer with bone metastases. However, this increases the risk of medication-related osteonecrosis of the jaw (MRONJ). The safety of long-term BMA administration in clinical practice remains unclear.

Epithelial-mesenchymal transition status is a remarkable biomarker for the combination treatment with avutometinib and defactinib in KRAS-mutated non-small cell lung cancer.

Background: Recent therapeutic strategies for KRAS-mutated cancers that inhibit the MAPK pathway have attracted considerable attention. 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.

The prognostic impact of peripheral blood eosinophil counts in metastatic renal cell carcinoma patients treated with nivolumab.

Although immune checkpoint inhibitors (ICIs) have gained approval for metastatic renal cell carcinoma (mRCC), the response rate is still limited. Therefore, it is urgent to explore novel markers of responses to ICIs that can help assess clinical benefits. Recently, it has been noted that peripheral blood eosinophil counts are an independent factor correlated with clinical outcome of ICIs in some types of cancer.

Japanese sake making using wild yeasts isolated from natural environments.

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.

First-Line Chemoimmunotherapy versus Sequential Platinum-Based Chemotherapy Followed by Immunotherapy in Patients with Non-Small Cell Lung Cancer with ≤49% Programmed Death-Ligand 1 Expression: A Real-World Multicenter Retrospective Study.

Background: The long overall survival (OS) observed among patients with non-small cell lung cancer (NSCLC) with high programmed death-ligand 1 (PD-L1) expression in chemoimmunotherapy (CIT) groups in previous phase III trials suggests the limited efficacy of CIT among the subgroup with ≤49% PD-L1 expression on tumor cells. Hence, sequential treatment with first-line platinum-based chemotherapy followed by second-line immune checkpoint inhibitor treatment (SEQ) is an option. This study examined whether first-line CIT would provide better outcomes than SEQ in patients with advanced NSCLC with ≤49% PD-L1 expression.

Predictive Value of Modified Glasgow Prognostic Score and Persistent Inflammation among Patients with Non-Small Cell Lung Cancer Treated with Durvalumab Consolidation after Chemoradiotherapy: A Multicenter Retrospective Study.

Background: Durvalumab consolidation after chemoradiotherapy (CRT) is a standard treatment for locally advanced non-small cell lung cancer (NSCLC). However, studies on immunological and nutritional markers to predict progression-free survival (PFS) and overall survival (OS) are inadequate. Systemic inflammation causes cancer cachexia and negatively affects immunotherapy efficacy, which also reflects survival outcomes.

Endobronchial metastasis of hepatocellular carcinoma treated with Lenvatinib: A case report.

Endobronchial metastasis (EBM) of hepatocellular carcinoma (HCC) is rare though HCC often metastasizes to the lungs. In this case report, a 74-year-old man with a history of HCC with chronic hepatitis C experienced hemoptysis and a dry cough. During immunotherapy for postoperative recurrent HCC, chest computed tomography (CT) revealed soft tissue shadows in the right upper and lower lobe bronchi, and we pathologically diagnosed as EBM of HCC using bronchoscopy.

Rationale and design of phase II clinical trial of dual inhibition with ramucirumab and erlotinib in exon 19 deletion-positive treatment-naïve non-small cell lung cancer with high PD-L1 expression (SPIRAL-3D study).

Background: Osimertinib is a standard treatment option for epidermal growth factor receptor (EGFR) mutation-positive non-small cell lung cancer (NSCLC). However, osimertinib monotherapy yields poor clinical outcomes in some patients, necessitating the development of novel treatment strategies. In addition, several studies have suggested that high programmed cell death-ligand 1 (PD-L1) expression is associated with poor progression-free survival (PFS) for osimertinib monotherapy in patients with advanced NSCLC harboring EGFR mutations.

[A Case of Primary Signet Ring Cell Carcinoma of the Urinary Bladder Showing Effectiveness of Chemotherapy with Gemcitabine and Cisplatin].

A 55-year-old female presented to the hospital with a complaint of gross hematuria. Transurethral resection of bladder tumor was performed. The specimens pathologically showed signet ring cells and no urothelial carcinoma components.

Prospective Observational Study Evaluating the Prognostic Value of the G8 Screening Tool for Extensive-Stage Small Cell Lung Cancer Patients Who Received Programmed Death-Ligand 1 Inhibitor plus Platinum-Etoposide Chemotherapy.

Background: Programmed death-ligand 1 (PD-L1) inhibitor plus platinum-etoposide chemotherapy is used as a first-line treatment for extensive-stage small cell lung cancer (ES-SCLC), regardless of age.

Objective: We examined the role of the Geriatric 8 (G8) screening tool for evaluating treatment outcomes in patients with ES-SCLC treated with PD-L1 inhibitor plus platinum-etoposide chemotherapy as first-line therapy.

Patients And Methods: Between September 2019 and October 2021, we prospectively evaluated patients with ES-SCLC treated with immunochemotherapy at ten institutions in Japan.

Significance of localized expression of full-length growth differentiation factor-15 in cachexia of advanced non-small cell lung cancer.

Purpose: Growth differentiation factor-15 (GDF-15) is one of the key cachexia-inducing factors. Clinical trials on therapies targeting GDF-15 for cancer and cancer cachexia are underway. While the role of circulating GDF-15 in cachexia has been clarified, the effects of GDF-15 expression within cancer cells remain to be fully elucidated.

TTF-1 Expression and Clinical Outcomes of Combined Chemoimmunotherapy in Patients With Advanced Lung Adenocarcinoma: A Prospective Observational Study.

Introduction: Lung adenocarcinoma with negative TTF-1 expression is believed to be a poor prognostic factor for certain systemic treatments. Nevertheless, the impact of TTF-1 expression on combined chemoimmunotherapy remains unclear. We aimed to investigate the relationship between tumor TTF-1 expression and the efficacy of combined chemoimmunotherapy in patients with advanced lung adenocarcinoma.

Comprehensive Kinase Activity Profiling Revealed the Kinase Activity Patterns Associated with the Effects of EGFR Tyrosine Kinase Inhibitor Therapy in Advanced Non-Small-Cell Lung Cancer Patients with Sensitizing EGFR Mutations.

EGFR mutations are strong predictive markers for EGFR tyrosine kinase inhibitor (EGFR-TKI) therapy in patients with non-small-cell lung cancer (NSCLC). Although NSCLC patients with sensitizing EGFR mutations have better prognoses, some patients exhibit worse prognoses. We hypothesized that various activities of kinases could be potential predictive biomarkers for EGFR-TKI treatment among NSCLC patients with sensitizing EGFR mutations.

Comparison of the prognosis of symptomatic cerebral infarction and pulmonary embolism in patients with advanced non-small cell lung cancer.

Background: Lung cancer patients face a high risk of thromboembolism (TE), which is considered to be a poor prognostic factor. However, the impact of symptomatic cerebral infarction (CI) and pulmonary embolism (PE) on the prognosis of advanced non-small cell lung cancer (NSCLC) patients is not fully understood.

Methods: We retrospectively identified 46 patients with advanced NSCLC who developed symptomatic CI or PE at five hospitals in Japan between January 2010 and December 2019.

Predictive value of p53 and AXL immunostaining for the efficacy of immune checkpoint inhibitor-based therapy after osimertinib treatment in patients with epidermal growth factor-mutant non-small cell lung cancer.

Background: Current evidence indicates that immune checkpoint inhibitors (ICIs) have a limited efficacy in patients with lung cancer harboring epidermal growth factor receptor (EGFR) mutations. However, there is a lack of data on the efficacy of ICIs after osimertinib treatment, and the predictors of ICI efficacy are unclear.

Methods: We retrospectively assessed consecutive patients with EGFR-mutant NSCLC who received ICI-based therapy after osimertinib treatment at 10 institutions in Japan, between March 2016 and March 2021.
