Cost-effectiveness analysis of first line pembrolizumab monotherapy for high programmed cell death ligand 1 expressed, advanced non-small cell lung cancer in Japan.

Background: Pembrolizumab monotherapy significantly extends progression-free and overall survival compared to platinum-based chemotherapy for advanced non-small cell lung cancer (NSCLC), but also has a significant impact on medical costs.

Aim: To clarify the health economic evidence for selecting the first-line treatment for patients with stage IV advanced NSCLC with a programmed cell death ligand 1 tumor proportion score of 50% or greater in Japan, we assessed the cost-effectiveness of pembrolizumab monotherapy compared with that of platinum-based chemotherapy.

Method: Using a Markov model, the study simulated three health states for patients, based on clinical data and utility values from KEYNOTE-024.

High-pH mobile phase in reversed-phase liquid chromatography-tandem mass spectrometry to improve the separation efficiency of aminoglycoside isomers.

In chromatography, the use of extreme conditions can often lead to unique separation selectivity. In this study, a highly basic mobile phase (pH > 11), which is not typically employed for reversed-phase liquid chromatography (RPLC), was utilized in RPLC-tandem mass spectrometry (MS/MS) to achieve effective separation between electrically neutral bases of aminoglycosides (AGs). A mixture of AGs was simultaneously analyzed using 500 mmol L ammonia aqueous solution (pH 11.

Empagliflozin cost-effectiveness analysis in Japanese heart failure with mildly reduced and preserved ejection fraction.

Aims: Empagliflozin, a sodium-glucose co-transporter 2 inhibitor, was shown to be effective in patients with heart failure with preserved ejection fraction (HFpEF) in the EMPEROR-Preserved trial. The present study aims to evaluate the cost-effectiveness of empagliflozin among Japanese patients with HFpEF.

Methods And Results: A Markov cohort model was developed to evaluate the cost-effectiveness of empagliflozin added to standard of care (SoC) compared with SoC alone in patients with HFpEF from the perspective of the Japanese healthcare system and with a lifetime horizon.

Cost-effectiveness of combination therapy of polatuzumab vedotin plus rituximab, cyclophosphamide, doxorubicin, and prednisolone for previously untreated diffuse large B-cell lymphoma in Japan.

Aim: The POLARIX trial showed that Pola + R-CHP (polatuzumab vedotin plus rituximab, cyclophosphamide, doxorubicin, and prednisolone) prolongs progression-free survival (PFS) in patients with previously untreated diffuse large B-cell lymphoma (DLBCL) compared with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone), the conventional standard of care, with a similar safety profile. However, Pola + R-CHP has not been evaluated from the viewpoint of health economics in Japan. This study evaluates the cost-effectiveness of Pola + R-CHP for previously untreated DLBCL from a Japanese public healthcare payer's perspective.

Prognostic Impact of Visceral Pleural Invasion in Resected Solitary Lung Metastases from Gastric Cancer.

Purpose: Pulmonary resection of metastases from gastric cancer is extremely rare because gastric cancer metastasis to the lungs or thoracic cavity occurs as multiple pulmonary metastases, carcinomatous lymphangitis, or carcinomatous pleurisy. Therefore, the significance of surgery for pulmonary metastasis of gastric cancer remains unclear. This study aimed to investigate the surgical outcomes and prognostic factors for survival after the resection of pulmonary metastases from gastric cancer.

Development of a HPLC system using a phase-separation multiphase flow as an eluent coupled to a silica-particle packed column.

The study reports the development of a high-performance liquid chromatography (HPLC) system in which a phase-separation multiphase flow as the eluent and a silica-particle based packed column as the separation column were combined to form the phase separation mode. Twenty-four types of mixed solutions of water/acetonitrile/ethyl acetate and water/acetonitrile were applied as eluents to the system at 20 °C. 2,6-Naphthalenedisulfonic acid (NDS) and 1-naphthol (NA) were injected as model analytes into the system.

Budget impact analysis of comprehensive genomic profiling for untreated advanced or recurrent solid cancers in Japan.

Aims: In Japan, the use of comprehensive genomic profiling (CGP) is only available for cancer patients who have no standard of care (SoC), or those who have completed SoC. This may lead to missed treatment opportunities for patients with druggable alterations. In this study, we evaluated the potential impact of CGP testing before SoC on medical costs and clinical outcome in untreated patients with advanced or recurrent biliary tract cancer (BTC), non-squamous non-small cell lung cancer (NSQ-NSCLC), or colorectal cancer (CRC) in Japan between 2022 and 2026.

Cost-effectiveness analysis of empagliflozin in patients with heart failure with reduced ejection fraction in Japan based on the EMPEROR-Reduced trial.

Background: Several studies have reported the cost-effectiveness of sodium-glucose co-transporter 2 inhibitors in heart failure patients; however, their economic implications have not been sufficiently elucidated in Japan.

Methods: A Markov cohort model was developed to evaluate the cost-effectiveness of empagliflozin plus standard of care (SoC) vs. SoC for patients with heart failure with reduced ejection fraction (HFrEF) in Japan.

Importance of TKI treatment duration in treatment-free remission of chronic myeloid leukemia: results of the D-FREE study.

Treatment-free remission (TFR) is a new goal for patients with chronic myeloid leukemia in chronic phase (CML-CP) with a sustained deep molecular response (DMR) to treatment with tyrosine kinase inhibitors (TKIs). However, optimal conditions for successful TFR in patients treated with second-generation (2G)-TKIs are not fully defined. In this D-FREE study, treatment discontinuation was attempted in newly diagnosed CML-CP patients treated with the 2G-TKI dasatinib who achieved BCR-ABL1 levels of ≤ 0.

Weight-adjusted urinary creatinine excretion predicts transplant outcomes in adult patients with acute myeloid leukemia in complete remission.

Sarcopenia is a prognostic factor for cancer. Because creatinine is formed from creatine phosphate in muscle tissue, urinary creatinine excretion (UCE) serves as an index of muscle volume. However, as of yet, there are no studies assessing the clinical impact of UCE or weight- adjusted urinary creatinine excretion (WA-UCE) on allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients.

[Clinical features of thyroid dysfunction in adult Japanese after allogeneic hematopoietic stem cell transplantation].

A 22-year-old man with a history of mediastinal germ cell tumor, which was diagnosed at age 20 and remained disease-free after chemotherapy, was diagnosed with acute myeloid leukemia (AML) M2 in January 2020. Karyotype analysis of bone marrow (BM) specimen at diagnosis detected 47,XXY, inv (16) in all cells. Following induction treatment, he achieved complete remission with a remarkable decrease in the minimal residual disease marker.

Mutation profiles of diffuse large B-cell lymphoma transformation of splenic B-cell lymphoma/leukemia, unclassifiable on whole-exome sequencing.

A 58-year-old male was diagnosed with splenic B-cell lymphoma/leukemia, unclassifiable (SPLL-U). The lymphoma transformed into diffuse large B-cell lymphoma (DLBCL), and multidrug chemotherapy and autologous stem cell transplantation achieved complete remission. Two years later, the lymphoma relapsed as SPLL-U.

Motor Progression and Nigrostriatal Neurodegeneration in Parkinson Disease.

Objective: The motor severity in Parkinson disease (PD) is believed to parallel dopaminergic terminal degeneration in the striatum, although the terminal was reported to be virtually absent by 4 years postdiagnosis. Meanwhile, neuromelanin-laden dopamine neuron loss in the substantia nigra (SN) elucidated a variability at early stages and gradual loss with less variability 10 years postdiagnosis. Here, we aimed to clarify the correlation between motor impairments and striatal dopaminergic terminal degeneration and nigral neuromelanin-laden dopamine neuron loss at early to advanced stages of PD.

Cyclophosphamide-induced cardiotoxicity at conditioning for allogeneic hematopoietic stem cell transplantation would occur among the patients treated with 120 mg/kg or less.

Cyclophosphamide (CY)-induced cardiotoxicity involves rare lethal complications. We previously reported the cardiac events of 811 allogeneic hematopoietic stem cell transplant (allo-HSCT) recipients; 12 out of 811 recipients (1.5%) developed fatal heart failure.

[A favorable clinical course of acute myeloid leukemia with t (6;21;8)(p23;q22;q22)].

Variants of the t (8;21) (q22;q22) involving chromosome 8, 21, and other chromosomes account for about 3% of all t (8;21) (q22;q22) in patients with acute myeloid leukemia (AML). However, the prognosis of AML with variant t (8;21) remains unknown due to the scarcity of reported cases. Herein we report a case of AML with t (6;21;8) (p23;q22;q22).

[Relationship between volunteer group participation and depressive symptoms in older Japanese: A 3-year JAGES longitudinal study using propensity score matching].

Objectives　In this study, we aim to clarify the optimal threshold for the frequency of volunteer group participation among older people aged 65 years and above, which is expected to prevent the risk of developing depression.Methods　We utilized longitudinal data from 2013 to 2016, collated by the Japan Gerontological Evaluation Study for people aged ≥65 years living in 24 municipalities and not certified as requiring long-term care. In addition, those who were not depressed in 2013 (≥5 points on the Geriatric Depression Scale-15) were followed up for 3 years and classified according to the frequency of participation in the volunteer group in 2013 (≥once per year, ≥once per month, ≥once per week).
