Association between immune-related adverse events and survival in patients with renal cell carcinoma treated with nivolumab plus ipilimumab: immortal time bias-corrected analysis.

Background: Immune-related adverse events (irAEs) in patients treated with immune check inhibitors are associated with favourable response rate and survivals in multiple cancers, including renal cell carcinoma (RCC). The aim of this study was to investigate how irAEs were associated with improved survivals in advanced RCC patients treated with nivolumab plus ipilimumab.

Materials And Methods: This retrospective study included patients who received nivolumab plus ipilimumab at six centres, institutions, or hospitals between September 2018 and February 2022.

Increasing age predicts adverse pathology including intraductal carcinoma of the prostate and cribriform patterns in deferred radical prostatectomy after upfront active surveillance for Gleason grade group 1 prostate cancer: analysis of prospective observational study cohort.

Background: In men undergoing upfront active surveillance, predictors of adverse pathology in radical prostatectomy specimens, including intraductal carcinoma of the prostate and cribriform patterns, remain unknown. Therefore, we aimed to examine whether adverse pathology in radical prostatectomy specimens could be predicted using preoperative patient characteristics.

Methods: We re-reviewed available radical prostatectomy specimens from 1035 men prospectively enrolled in the PRIAS-JAPAN cohort between January 2010 and September 2020.

A Case of Septic Pulmonary Embolism Caused by Pyelonephritis With Klebsiella pneumoniae in a Patient With Poorly Controlled Type 2 Diabetes Mellitus.

Septic pulmonary embolism (SPE) is caused by the microbe that is responsible for any clinical condition that may include urinary tract infections as in this case. We report a case of pyelonephritis with that led to SPE in an 80-year-old woman with poorly controlled diabetes mellitus (DM). Computed tomography (CT) revealed multiple nodules in the peripheral area of the bilateral lung and a contrast defect in the right renal vein, which was suspected to be an embolism.

A phase II randomized trial of metastasis-directed therapy with alpha emitter radium-223 in men with oligometastatic castration-resistant prostate cancer (MEDAL).

Background: The significance of metastasis-directed therapy for oligometastatic prostate cancer has been widely discussed, and targeted therapy for progressive sites is a feasible option as a multidisciplinary treatment for castration-resistant prostate cancer (CRPC). When oligometastatic CRPC with only bone metastases progresses after targeted therapy, it tends to progress as multiple bone metastases. The progression of oligometastatic CRPC after targeted therapy may be due in part to the presence of micrometastatic lesions that, though undetected on imaging, were present prior to targeted therapy.

Pretreatment Hemoglobin Levels and Platelet-to-Lymphocyte Ratio Predict Survival Benefit from Pembrolizumab in Advanced Urothelial Carcinoma.

Background/aim: Several prognostic risk factors have been recognized when using cisplatin-based conventional chemotherapy for the treatment of advanced urothelial carcinoma (UC); these include performance status (PS), liver metastasis, hemoglobin (Hb) levels, time from prior chemotherapy (TFPC), and other systemic inflammation scores including neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). However, the benefit of these indicators for predicting outcome of immune checkpoint inhibitors is not fully understood. Here, we investigated the predictive value of the indicators in patients who received pembrolizumab for the treatment of advanced UC.

Peritoneal closure and the processus vaginalis transection method to prevent inguinal hernia after robot-assisted radical prostatectomy.

Objectives: Postoperative inguinal hernia (IH) is one of the most common complications of radical prostatectomy (RP) including robot-assisted RP (RARP). However, a procedure to prevent IH after RARP has not been established. We investigated the impact of processus vaginalis transection (PVT) and PVT with peritoneal closure on IH after RARP.

Clinical outcomes of nivolumab plus ipilimumab in patients with metastatic non-clear cell renal cell carcinoma: Real-world data from a Japanese multicenter retrospective study.

Objectives: Although nivolumab plus ipilimumab has become a standard treatment regimen for metastatic clear cell renal cell carcinoma (ccRCC), its efficacy in non-clear cell carcinoma (nccRCC) has not been fully examined. In the current study, we evaluated the clinical outcomes of nivolumab plus ipilimumab in nccRCC compared with ccRCC.

Methods: We retrospectively analyzed 22 patients with metastatic and/or locally advanced unresectable nccRCC who received nivolumab plus ipilimumab as a first-line therapy and compared them with 107 patients with ccRCC.

Clinical outcomes of intraductal carcinoma or cribriform in radical prostatectomy specimens of men opting for active surveillance: data from the PRIAS-JAPAN study.

Background: Among early stage prostate cancer patients, intraductal carcinoma of the prostate (IDC-P) and invasive cribriform are key prognostic factors; however, their presence and clinical significance following active surveillance (AS) are unknown. In men who opted for AS, we aimed to examine the presence and impact of IDC-P or cribriform, utilizing radical prostatectomy (RP) specimens.

Methods: We re-reviewed 137 RP specimens available in the PRIAS-JAPAN prospective cohort between January 2010 and September 2020.

Paraganglioma with High Levels of Dopamine, Dopa Decarboxylase Suppression, Dopamine β-hydroxylase Upregulation and Intra-tumoral Melanin Accumulation: A Case Report with a Literature Review.

Object Exclusively dopamine-producing pheochromocytoma/paraganglioma (PPGL) is an extremely rare subtype. In this condition, intratumoral dopamine β-hydroxylase (DBH), which controls the conversion of norepinephrine from dopamine, is impaired, resulting in suppressed norepinephrine and epinephrine production. However, the rarity of this type of PPGL hampers the understanding of its pathophysiology.

Late recurrence of late-onset large cell calcifying Sertoli tumor successfully managed by early surgical intervention.

Large cell calcifying Sertoli tumor is an uncommon testicular neoplasm. We present a case of a 36-year-old man with a late-onset large cell calcifying Sertoli tumor that resulted in a solitary lung metastasis 5 years after radical orchiectomy. Pulmonary wedge resection was performed, and there was no recurrence at the 18-month follow-up after resection of the lung metastasis.

Platelet-to-Lymphocyte Ratio Predicts the Efficacy of Pembrolizumab in Patients With Urothelial Carcinoma.

Background/aim: This study aimed to determine useful predictive factors for selecting patients with advanced urothelial carcinoma (UC) who might benefit clinically from treatment with pembrolizumab.

Patients And Methods: We retrospectively analyzed 54 patients who underwent pembrolizumab treatment for UC. The hemoglobin, albumin, lymphocyte and platelet (HALP) score, neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) were calculated as indices of systemic inflammatory response, and the relationships between these scores and the initial tumor response or overall survival, as well as other clinicopathological factors, were assessed.

A case of juvenile-onset pheochromocytoma with KIF1B p.V1529M germline mutation.

In 2008, a familial noradrenergic pheochromocytoma (PCC) with a KIF1B germline mutation in exon 41 was reported in a 24-year-old female proband and her family. However, in 2020, the same research group reported that the cause of PCC in this family was a MAX germline mutation and was not due to the KIF1B mutation. In this study, we investigated the pathogenicity of a KIF1B germline mutation detected in a 26-year-old woman with juvenile-onset noradrenergic PCC.
