Clinical impact of cancer cachexia on the outcome of patients with non-small cell lung cancer with PD-L1 tumor proportion scores of ≥50% receiving pembrolizumab monotherapy versus immune checkpoint inhibitor with chemotherapy.

This retrospective, multicenter cohort study aimed to determine whether cancer cachexia serves as a biomarker for determining the most effective treatment for patients having non-small-cell lung cancer (NSCLC) with high programmed death ligand 1 (PD-L1) expression treated with immune checkpoint inhibitors (ICIs) alone or combined with chemotherapy (ICI/chemotherapy). We included 411 patients with advanced NSCLC with a PD-L1 tumor proportion score of ≥50%. The patients were treated with pembrolizumab monotherapy or ICI/chemotherapy.

combined with L858R mutation reduced afatinib sensitivity and associated to early recurrence in lung cancer.

Background: The third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) osimertinib is widely used as a first-line treatment for -mutated non-small cell lung cancer (NSCLC). However, there is no established treatment for osimertinib resistance, so second-generation afatinib is an alternative treatment option. The purpose of this study was to elucidate gene alterations associated with afatinib efficacy and resistance by analyzing cell-free DNA (cfDNA) obtained from patients with -mutated NSCLC.

Dynamic FDG PET/CT for differentiating focal pelvic uptake in patients with gynecological cancer.

This study aimed to evaluate the ability of serial whole-body dynamic PET/CT to differentiate physiological from abnormal F-FDG uptake in the abdomen and pelvis of gynecological cancer patients. We conducted a retrospective study of 61 F-FDG PET/CT examinations for suspected gynecological malignancies or metastases between March 2018 and January 2020. Our protocol included four-phase dynamic whole-body scans.

YAP regulates HER3 signaling-driven adaptive resistance to RET inhibitors in RET-aberrant cancer.

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.

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.

CYFRA 21-1 predicts efficacy of combined chemoimmunotherapy in patients with advanced non-small cell lung cancer: a prospective observational study.

Background: Tumor markers such as serum carcinoembryonic antigen (CEA) and cytokeratin fragment 19 (CYFRA 21-1) are utilized for assessing the effectiveness of chemotherapy in non-small cell lung cancer (NSCLC) patients. Yet, it remains uncertain whether these markers can reliably forecast responses to combined chemoimmunotherapy. Our study aimed to examine the significance and effectiveness of these markers in predicting responses among NSCLC patients undergoing combined chemoimmunotherapy.

Viral eradication reduces all-cause mortality in patients with chronic hepatitis C virus infection who had received direct-acting antiviral therapy.

Background And Aims: The impact of hepatitis C virus (HCV) eradication via direct-acting antiviral (DAA) therapy on overall mortality, particularly non-liver-related mortality, is understudied.

Methods: We recruited 4180 patients with chronic HCV infection who achieved sustained virological response (SVR) (HCV eradication) through DAA therapy (n = 2501, SVR group) or who did not receive antiviral therapy (n = 1679, non-SVR group); 1236 from each group were chosen using propensity score matching. Causes of death and all-cause mortality, including non-liver-related diseases, were investigated.

[Resection Case of Residual Gastric MiNEN(MANEC)Diagnosed 44 Years after Gastrectomy].

MANEC, a subtype of MiNEN, is a rare disease, even rarer when found in the remnant stomach. We report a residual gastric MANEC case found 44 years after subtotal gastrectomy. The patient was an 80-year-old female who underwent subtotal gastrectomy at 36 years old and was referred to our hospital for anorexia and weight loss.

Depth of response and treatment outcomes of immune checkpoint inhibitor-based therapy in patients with advanced non-small cell lung cancer and high PD-L1 expression: An exploratory analysis of retrospective multicenter cohort.

The association between depth of response (DpR) and treatment outcomes has been documented across various types of cancer. Immune checkpoint inhibitor (ICI)-based treatment is globally used as first-line treatment for non-small cell lung cancer (NSCLC) with programmed death-ligand 1 (PD-L1) expression ≥ 50%. However, in this population, the significance of DpR is not elucidated.

The impact of renal function on initial therapy in transplant-ineligible multiple myeloma patients.

The prognosis for multiple myeloma (MM) patients has improved with the advent of new drugs, but the prognosis with renal impairment (RI) is poor. The choice of treatment in such cases is critical, but there are no set criteria. We examined the impact of RI on initial therapy in transplant-ineligible MM patients.

Combination of Hydrogen Inhalation and Hypothermic Temperature Control After Out-of-Hospital Cardiac Arrest: A Post hoc Analysis of the Efficacy of Inhaled Hydrogen on Neurologic Outcome Following Brain Ischemia During PostCardiac Arrest Care II Trial.

Objective: The Efficacy of Inhaled Hydrogen on Neurologic Outcome Following Brain Ischemia During Post-Cardiac Arrest Care (HYBRID) II trial (jRCTs031180352) suggested that hydrogen inhalation may reduce post-cardiac arrest brain injury (PCABI). However, the combination of hypothermic target temperature management (TTM) and hydrogen inhalation on outcomes is unclear. The aim of this study was to investigate the combined effect of hydrogen inhalation and hypothermic TTM on outcomes after out-of-hospital cardiac arrest (OHCA).

Impact of Antiplatelet Therapy on 5-Year Outcomes After Fractional Flow Reserve-Guided Deferral of Revascularization in Nonsignificant Obstructive Coronary Artery Disease.

Background: Because the clinical benefit of antiplatelet therapy (APT) for patients with nonsignificant coronary artery disease (CAD) remains poorly understood, we evaluated it in patients after fractional flow reserve (FFR)-guided deferral of revascularization.

Methods And Results: From the J-CONFIRM (Long-Term Outcomes of Japanese Patients with Deferral of Coronary Intervention Based on Fractional Flow Reserve in Multicenter Registry), we investigated 265 patients with deferred lesions who did not require APT for secondary prevention of cardiovascular disease. A 2-year landmark analysis assessed the relationship between APT at 2 years and 5-year major cardiac adverse events (MACE: composite of all-cause death, target vessel-related myocardial infarction, clinically driven target vessel revascularization).

Unraveling the influence of TTF-1 expression on immunotherapy outcomes in PD-L1-high non-squamous NSCLC: a retrospective multicenter study.

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.

Purpose: To assess the effectiveness of switching from the concomitant use of brinzolamide 1% (BZM) and brimonidine 0.1% (BMD) to a BZM/BMD fixed-dose combination (BBFC) for the reduction of corneal epithelial damage.

Study Design: Retrospective cohort study.

Super paramagnetic iron oxide contrast-enhanced magnetic resonance imaging was useful in differentiating an insulinoma from an accessory spleen: a case report with review of literature.

When a neuroendocrine tumor with abundant blood flow is located in the pancreatic tail, it is difficult to distinguish it from accessory spleen. The patient was a 71-year-old woman who was admitted with impaired consciousness and hypoglycemia, raising suspicion of insulinoma. The selective arterial calcium injection test suggested a lesion in the pancreatic tail.

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.
