Introduction: Effectiveness and safety of second-line tyrosine kinase inhibitors (TKIs) in patients with metastatic renal cell carcinoma (mRCC) for whom first-line immuno-oncology (I-O) combination therapy was discontinued because of adverse events (AEs) remain to be determined.

Patients And Methods: Clinicopathological data were retrospectively collected from 34 institutions between August 2018 and January 2022 for 243 patients with mRCC who received second-line TKIs after first-line I-O combination therapy. Two patients who requested discontinuation of first-line I-O combination therapy were excluded.

Real-world clinical usage and efficacy of apalutamide in men with nonmetastatic castration-resistant prostate cancer: a multi-institutional study in the CsJUC.

Objective: To evaluate the real-world clinical usage and effectiveness of apalutamide in men with nonmetastatic castration-resistant prostate cancer (nmCRPC).

Methods: We retrospectively reviewed the data of 186 men who received apalutamide across 17 institutions. The primary outcomes were the clinical usage of apalutamide for nmCRPC: prior usage of other androgen receptor signaling inhibitors (ARSIs), prior radical treatment, and the distribution of the prostate-specific antigen (PSA) doubling time (PSA-DT) at the initial administration of apalutamide.

Eosinophil is a predictor of severe immune-related adverse events induced by ipilimumab plus nivolumab therapy in patients with renal cell carcinoma: a retrospective multicenter cohort study.

Introduction: Immune-related adverse events (irAEs) induced by immune checkpoint inhibitors are difficult to predict and can lead to severe events. Although it is important to develop strategies for the early detection of severe irAEs, there is a lack of evidence on irAEs associated with ipilimumab plus nivolumab therapy for metastatic renal cell carcinoma (RCC). Therefore, this study aimed to investigate the association between eosinophil and severe irAEs in patients receiving ipilimumab plus nivolumab therapy for RCC.

Improved prognosis of de novo metastatic prostate cancer after an introduction of life-prolonging agents for castration-resistant prostate cancer.

Background: In Japan, since 2014, new treatments such as androgen receptor signaling inhibitors and cabazitaxel have become applicable for metastatic castration-resistant prostate cancer (mCRPC), leading to dramatic changes in treatment options.

Objective: This study aims to evaluate the impact of recent advancements in treatment options on the overall survival (OS) of patients diagnosed with de novo metastatic castration-sensitive prostate cancer (mCSPC) in Japan.

Methods: A retrospective analysis was conducted on 2450 Japanese men diagnosed with de novo mCSPC between 2008 and 2018.

Primary resistance to nivolumab plus ipilimumab therapy affects second-line treatment outcomes in patients with metastatic renal cell carcinoma.

Nivolumab plus ipilimumab (NIVO+IPI) has a long-term response rate of 30% for patients with metastatic renal cell carcinoma (mRCC). However, 20% of patients develop primary resistant disease (PRD) to NIVO+IPI and show poor survival outcomes. In this study, we aimed to evaluate the effect of PRD as a second-line treatment in patients with mRCC.

Cutaneous ureterostomy following robot-assisted radical cystectomy: a multicenter comparative study of transperitoneal versus retroperitoneal techniques.

Background: The aim of this study was to evaluate the differences in perioperative outcomes between transperitoneal and retroperitoneal techniques in cutaneous ureterostomy (CUS).

Methods: Between 2018 and 2023, 55 patients underwent CUS following robot-assisted radical cystectomy. Among the 55 patients, we compared 33 patients who underwent transperitoneal CUS (t-CUS) and 22 who underwent retroperitoneal CUS (r-CUS).

Robot-assisted nephroureterectomy using the GelPoint Platform with a focus on optimizing the port position and specimen retrieval.

Introduction: One of the factors that makes robot-assisted nephroureterectomy difficult is that the optimal port position differs between nephrectomy and bladder cuff excision. In addition, how best to retrieve the specimen after resection while minimizing the size of the wound is a challenge in robot-assisted surgery. To solve these problems, we designed a surgical technique for robot-assisted nephroureterectomy using the GelPoint Platform with a focus on port position optimization and specimen retrieval.

External validation of hemoglobin and neutrophil levels as predictors of the effectiveness of ipilimumab plus nivolumab for treating renal cell carcinoma.

Introduction: Pretreatment hemoglobin and neutrophil levels were previously reported to be important indicators for predicting the effectiveness of ipilimumab plus nivolumab (IPI + NIVO) therapy for renal cell carcinoma (RCC). Therefore, we aimed to validate this in a large external cohort.

Methods: In total, 172 patients with RCC who underwent IPI + NIVO treatment at a multicenter setting were divided into three groups according to their pretreatment hemoglobin and neutrophil levels (group 1: non-anemia; group 2: anemia and low-neutrophil; and group 3: anemia and high-neutrophil).

Retroperitoneal cutaneous ureterostomy following radical cystectomy: A multicenter comparative study of robotic versus open surgery.

Introduction: The aim of this study was to evaluate the differences in perioperative outcomes of cutaneous ureterostomy (CUS) between open surgery (open radical cystectomy, ORC) and robot-assisted surgery (robot-assisted radical cystectomy, RARC), including the stent-free rate, readmission rates due to urinary tract infection (UTI), and changes in renal function.

Methods: Between 2005 and 2023, a total of 37 patients underwent CUS following ORC, while 24 patients underwent CUS following RARC. Perioperative outcomes were compared between these two groups.

Methods: Fifty-five patients who underwent RICIC at two institutions were evaluated (Bricker, n = 23; Wallace, n = 32). We investigated changes in estimated glomerular filtration rate and hydronephrosis before surgery and at 3, 6, and 12 months after surgery.

Impact of lymph node dissection on surgical and oncological outcomes in patients undergoing robot-assisted radical cystectomy for bladder cancer: a multicenter retrospective study.

This study was performed to clarify the therapeutic and diagnostic roles of lymph node dissection (LND) by examining the impact of LND and lymph node yield (LNY) on oncological outcomes in patients undergoing robot-assisted radical cystectomy (RARC). Between 2014 and 2021, 216 patients underwent LND during RARC at Tokushima University Hospital and affiliated hospitals. Among the 216 patients, we compared 115 patients with an LNY of ≥ 20 and 101 with an LNY of < 20 to investigate the impact of LNY on surgical and oncological outcomes.

Treatment patterns and prognosis in patients with Bacillus Calmette-Guérin-exposed high-risk non-muscle invasive bladder cancer: a real-world data analysis.

Purpose: The International Bladder Cancer Group designated the subgroup that is resistant to Bacillus Calmette-Guérin (BCG) but does not meet the criteria for BCG-unresponsive NMIBC as "BCG-exposed high-risk NMIBC" to guide optimal trial design. We aimed to investigate the treatment patterns and prognoses of patients with BCG-exposed NMIBC.

Methods: We conducted a retrospective chart review of 3283 patients who received intravesical BCG therapy for NMIBC at 14 participating institutions between January 2000 and December 2019.

The impact of second transurethral resection on survival outcomes in patients with non-muscle-invasive bladder cancer treated with bacillus Calmette-Guérin therapy.

Objective: Several guidelines recommended that second transurethral resection should be performed in patients with diagnosis of high-risk non-muscle-invasive bladder cancer. However, therapeutic benefits of second transurethral resection before bacillus Calmette-Guérin intravesical instillation were conflicting amongst previous studies. We investigated the prognostic impact of second transurethral resection before bacillus Calmette-Guérin instillation in high-risk non-muscle-invasive bladder cancer patients.

Impact of early urinary catheter removal on successful voiding and physical function in stroke patients.

Objective: The aim of the present study was to identify factors related to the success of trial without catheter (TWOC) in patients with stroke and to examine the effect of the timing of urinary catheter removal on the course of stroke.

Methods: Patients who were admitted to the Stroke Care Unit of our institution between March 2018 and October 2021 were included. To identify factors related to success of TWOC, a multivariate analysis was performed on the patient's condition at admission and catheter indwelling time.
