Characterization of PSA dynamics and oncological outcomes in patients with metastatic hormone-sensitive prostate cancer treated with androgen receptor signaling inhibitors.

Background: This study investigated the characteristics of prostate-specific antigen (PSA) dynamics when androgen receptor signaling inhibitor (ARSI), or vintage agent (bicalutamide) was used for patients with metastatic hormone-sensitive prostate cancer (mHSPC).

Patients And Methods: A total of 213 mHSPC patients from each of the ARSI and bicalutamide groups treated between 2015 and 2022 were selected from multiple institutions using propensity score-matched analysis to align backgrounds. PSA progression-free survival (PFS) and overall survival (OS) were assessed.

Predicting time to castration resistance with androgen-receptor signaling inhibitors in hormone-sensitive prostate cancer: data from ULTRA-Japan Consortium.

Background: Androgen-receptor signaling inhibitors (ARSIs) become the new standard of care for metastatic hormone-sensitive prostate cancer (mHSPC). It is unknown whether time to castration resistance (TTCR), when using the first-line ARSIs, offers predictive value in mHSPC. We sought to assess the clinical outcomes for mHSPC patients treated with first-line ARSIs focusing on the TTCR.

Increased Red Cell Superoxide Dismutase Activity Is Associated with Cancer Risk: A Hidaka Cohort Study.

Unlabelled: Superoxide dismutase (SOD) catalyzes the highly reactive superoxide anion to form hydrogen peroxide, which facilitates cell proliferation and death. We investigated whether red cell SOD (R-SOD) activity is associated with an increased risk of cancer in a Japanese general population. We prospectively analyzed data from 1,921 participants (800 men and 1,121 women; age, 58.

Real-world outcomes in patients with metastatic castration-resistant prostate cancer beyond progression after upfront androgen receptor signaling inhibitor.

Background: Upfront androgen receptor signaling inhibitor (ARSI) along with androgen deprivation therapy is the current standard of care for metastatic castration-sensitive prostate cancer. However, evidence on second-line therapy after upfront ARSI is scarce. We aimed to evaluate the oncological outcome of ARSI versus docetaxel (DOC) after upfront ARSI therapy in a real-world clinical practice.

Mechanistic insights into lethal hyper progressive disease induced by PD-L1 inhibitor in metastatic urothelial carcinoma.

Hyper progressive disease (HPD) is a paradoxical phenomenon characterized by accelerated tumor growth following treatment with immune checkpoint inhibitors. However, the pathogenic causality and its predictor remain unknown. We herein report a fatal case of HPD in a 50-year-old man with metastatic bladder cancer.

Clinical outcomes and prognostic factors in metastatic nonclear cell renal cell carcinoma treated with immuno-oncology combination therapy.

Background: Metastatic nonclear cell renal cell carcinoma (nccRCC) is a heterogeneous disease with poor prognosis. The clinical characteristics and prognostic factors of immuno-oncology (IO) combination therapy for nccRCC are not well known. This study analyzed patients with metastatic nccRCC treated with IO combination therapy.

C-Reactive Protein-Albumin Ratio Predicts Objective Response to Enfortumab Vedotin in Metastatic Urothelial Carcinoma.

Background: Enfortumab vedotin (EV), an antibody-drug conjugate that targets Nectin-4, is used for patients with metastatic urothelial carcinoma who have experienced progression on platinum-based chemotherapy and checkpoint inhibitors. Despite the widespread use of the drug, evidence remains scarce regarding clinical indicators that can predict the response to EV treatment.

Objective: We aimed to explore the predictive value of clinical indicators derived from peripheral blood tests for treatment responses to EV.

Plasma Gel Matrix as a Promising Carrier of Epigallocatechin Gallate for Regenerative Medicine.

Plasma gel (PG) is a protein matrix prepared from platelet-poor plasma and can be utilized as a drug carrier for controlled release. We previously demonstrated its applicability as a carrier of polyphosphate. Epigallocatechin-3-gallate (EGCG) is the main flavonoid found in green tea and functions as a strong antioxidant.

Real world evidence of enfortumab vedotin in patients with advanced urothelial cancer: A multicenter observational study.

Objectives: To explore the characteristics of patients and assess the effectiveness of enfortumab vedotin (EV) in those with treatment-resistant advanced urothelial cancer in a real-world setting.

Patients And Methods: A multicenter observational study was conducted on 103 evaluable patients with advanced urothelial cancer who received EV. Outcomes were assessed by radiographic response, progression-free survival (PFS), and overall survival (OS), with treatment-related adverse events (trAEs).

Hypoxia-inducible factor-prolyl hydroxylase inhibitor Roxadustat (FG-4592) reduces renal fibrosis in Dahl salt-sensitive rats.

Objective: Although hypoxia-inducible factor-prolyl hydroxylase (HIF-PH) inhibitors have been developed for the treatment of renal anemia, their effects on cardiac and renal dysfunction remain unknown. We previously reported on Dahl salt-sensitive rats, in a rat model of salt-sensitive hypertension, that exhibited anemia and impaired expression of duodenal iron transporters after the development of hypertensive cardiac and renal dysfunction. Therefore, we investigated the effects of Roxadustat (FG-4592), an HIF-PH inhibitor, on anemia, iron regulation, and cardiac and renal dysfunction in Dahl salt-sensitive rats.

Plasma Gel Made of Platelet-Poor Plasma: In Vitro Verification as a Carrier of Polyphosphate.

Plasma gel (PG) is a blood-derived biomaterial that can be prepared by heating or chemical cross-linking without the aid of intrinsic coagulation activity and has gradually been applied in the field of esthetic surgery. To explore the applicability of PG in regenerative therapy or tissue engineering, in this study, we focused on the advantages of the heating method and verified the retention capacity of the resulting PG for polyphosphate (polyP), a polyanion that contributes to hemostasis and bone regeneration. Pooled platelet-poor plasma (PPP) was prepared from four healthy male adult donors, mixed with synthetic polyP, and heated at 75 °C for 10 or 30 min to prepare PG in microtubes.

Nephron-sparing ureteroscopic surgery vs. radical nephroureterectomy: comparable survival-outcomes in upper tract urothelial carcinoma.

Purpose: This study investigates the utility of ureteroscopic surgery (URS) as an alternative to radical nephroureterectomy (RNU) in managing upper tract urothelial carcinoma (UTUC), with a focus on survival outcomes and re-evaluation of current the European Association of Urology guidelines criteria.

Methods: We conducted a retrospective, multi-institutional review of 143 UTUC patients treated with URS (n = 35) or RNU (n = 108). Clinicopathological factors were analyzed, and survival outcomes were assessed using Kaplan-Meier analysis and Cox proportional-hazards models.

Prognostic Impact of Immune-Related Adverse Events as First-Line Therapy for Metastatic Renal Cell Carcinoma Treated With Nivolumab Plus Ipilimumab: A Multicenter Retrospective Study.

Background: Immune checkpoint inhibitors can cause various immune-related adverse events (irAEs). This study aimed to evaluate the association between the incidence of irAEs and oncological outcomes of metastatic renal cell carcinoma (mRCC) treated with nivolumab plus ipilimumab as first-line therapy.

Patients And Methods: We retrospectively analyzed data from 69 patients with mRCC treated with nivolumab plus ipilimumab as first-line therapy between September 2018 and September 2021 at 4 institutions.

Dimethyl Fumarate Ameliorated Cardiorenal Anemia Syndrome and Improved Overall Survival in Dahl/Salt-Sensitive Rats.

Cardiovascular disease, chronic kidney disease, and anemia are known to adversely affect each other. Inflammation is commonly involved in these diseases. Cardiorenal anemia syndrome (CRAS) is the name given to this mutually harmful condition.
