Choroidal Metastasis From Papillary Renal Cell Carcinomas: A Case Report and a Review of the Literature.

Choroidal metastasis originating from renal cell carcinomas (RCCs) is rare. To the best of our knowledge, 31 cases of choroidal metastasis from RCC have been reported in the English literature as of January 31, 2024. Nevertheless, physicians need to be vigilant in recognizing this condition, as its progression impacts the quality of life (QOL) of affected patients.

Efficacy of abiraterone acetate for high-risk hormone-naïve metastatic prostate cancer: A comparison with combined androgen blockade therapy with bicalutamide and androgen deprivation therapy alone.

Background: The treatment landscape for men with metastatic hormone-naïve prostate cancer (mHNPC) has dramatically changed with the approval of next-generation anti-androgen drugs. We compared the treatment efficacy of abiraterone with that of combined androgen blockade (CAB) therapy and androgen deprivation therapy (ADT) alone in men with high-risk mHNPC.

Methods: In total, 146 Japanese men with high-risk mHNPC were retrospectively analyzed.

Characterization of Aldosterone-producing Cell Cluster (APCC) at Single-cell Resolution.

Context: The adrenal cortex consists of zona glomerulosa (ZG), fasciculata (ZF), and reticularis. Aldosterone-producing cell clusters (APCCs) that strongly express aldosterone synthase (CYP11B2) are frequently found in adult adrenals and harbor somatic mutations that are also detected in aldosterone-producing adenomas (APAs). Primary aldosteronism is mainly caused by APAs or idiopathic hyperaldosteronism (IHA).

Case Study: A Japanese patient with metastatic renal cell carcinoma who achieved long-term treatment-free survival with pembrolizumab and axitinib in the KEYNOTE-426 phase III trial of pembrolizumab and axitinib versus sunitinib.

Introduction: Our patient treated with pembrolizumab and axitinib is one of the longest survivors in Japan on KEYNOTE 426, despite adverse events, including delayed-onset hepatitis. We herein present a detailed clinical course and short discussion on the case.

Case Presentation: This was a 49-year-old male with clear cell renal cell carcinoma and lung metastases.

Oncological outcomes of dose reductions in cisplatin due to renal dysfunction for patients with metastatic urothelial carcinoma.

Objective: To investigate whether dose reductions in cisplatin due to renal dysfunction were associated with worse clinical outcomes in metastatic urothelial carcinoma (UC) patients.

Patients And Methods: One hundred and fifty one metastatic UC patients who received first-line gemcitabine plus cisplatin (GC) salvage chemotherapy without a previous history of peri-surgical chemotherapy were included in this retrospective study. Patients with endogenous creatinine clearance of 60 mL/min or more were treated with a full dose of cisplatin, while those with 45-59 and 30-44 mL/min were treated with 75% and 50% doses, respectively.

A case in which bladder cancer invaded the ureteral orifice and was resected via photodynamic diagnosis-assisted transurethral resection involving orally administered 5-aminolevulinic acid.

Introduction: Transurethral resection of bladder tumor is widely used in combination with photodynamic diagnosis to treat non-muscle invasive bladder cancer. We experienced an intriguing case, in which bladder cancer infiltrated into the right ureteral orifice and was resected via photodynamic diagnosis-assisted transurethral resection involving the oral administration of 5-aminolevulinic acid.

Case Presentation: This case was a 71-year-old Japanese man.

A case of castration-resistant prostate cancer with liver metastases achieved a complete response by docetaxel chemotherapy.

Castration-resistant prostate cancer (CRPC) patients with liver metastases have an extremely poor prognosis. Herein, we report a rare patient who achieved a complete response by docetaxel chemotherapy for this aggressive disease. A 67-year-old Japanese male diagnosed with local prostate cancer [initial prostate specific antigen (PSA) of 10.

Efficacy of Nivolumab Plus Ipilimumab in a Patient With Renal Cell Carcinoma Concomitant With Cardiac Metastasis: A Case Report.

Background/aim: Patients with metastatic renal cell carcinoma (RCC) with cardiac metastasis have had poor outcomes in the era of molecular targeted therapy. There are few reported outcomes for patients with cardiac metastasis of RCC treated with immune checkpoint inhibitors (ICIs).

Case Report: A 32-year-old female presented with metastatic RCC (unclassified type) with contralateral renal and cardiac metastases, as well as renal hilar lymph node metastases (cT4N2M1).

Meningeal carcinomatosis from bladder cancer: A case report and review of the literature.

A 66-year-old Japanese male patient was referred to Saitama Medical University International Medical Center for treatment of bladder cancer (clinical stage T2 or higher without metastasis), and underwent radical cystectomy with pelvic lymphadenectomy. The histopathological diagnosis was high-grade urothelial carcinoma (pathological stage T2bN2, ly1, v0) and 2 cycles of adjuvant systemic chemotherapy (gemcitabine plus cisplatin) were administered. At 15 months after the operation, mediastinal and lung hilar lymph nodes and multiple bone metastases were identified on computed tomography imaging.
