Presurgical immune-oncology/tyrosine kinase inhibitor combination therapy for renal cell carcinoma with a vena cava tumor thrombus: a single-institution case series.

Background: Although current guidelines recommend administering adjuvant immunotherapy following resection of advanced primary renal cell carcinoma (RCC), the clinical benefit of presurgical immunotherapy for patients with RCC remains uncertain. Case Description: We conducted a retrospective analysis of five patients diagnosed with RCC who developed inferior vena cava (IVC) tumor thrombus and were treated with radical nephrectomy following combined immunotherapy with a tyrosine kinase inhibitor. The median follow-up after nephrectomy was 23 months (range, 19-30 months). In all cases, the size of the IVC tumor thrombus decreased, and three of the cases demonstrated a decrease in the tumor thrombus level. Surgical margins were negative in all cases, and none of the patients experienced any major intraoperative complications. However, adhesions were encountered at the operative sites during surgery in all cases. One patient required a lymphatic intervention due to abdominal lymphatic leakage (Clavien IIIa) within 90 days after operation. Our case series demonstrated a median progression-free survival (PFS) of 11 months [95% confidence interval (CI)]: 5.5-22.5 months). No patient died during the follow-up period. Conclusions: Presurgical therapy combined with immunotherapy and tyrosine kinase inhibitors warrants consideration. Nevertheless, surgeons should be mindful of the difficulties that may arise beyond the clinical stage.

Time to revisit role of transcatheter balloon aortic valvuloplasty: a bridge-therapy to subsequent treatment case report.

Recently there has been a noticeable resurgence in the usage of percutaneous balloon aortic valvuloplasty (BAV) by the development of less invasive endovascular therapies including transcatheter aortic valve implantation (TAVI). We performed BAV in a 91-year-old man with end-stage severe symptomatic aortic stenosis (AS) and an impending abdominal aortic aneurysm (AAA) rupture who had been refused surgical treatment because of the comorbidities with stage V chronic kidney disease (CKD) and severe left ventricular dysfunction. Improvement in hemodynamics and kidney function was observed after BAV. Subsequently, we performed endovascular aneurysm repair (EVAR) successfully for AAA using iodinated contrast. No deterioration of kidney function was confirmed after the procedure. The patient was discharged without any adverse events. At present, the possibilities of TAVI or surgical aortic valve replacement (s-AVR) are under consideration as the definitive therapy for the upcoming aortic valve restenosis. In conclusion, this inoperable patient with multiple comorbidities was successfully treated, at lower risk, by catheter-based two-stage therapy.

[Evaluation of supplemental administration of Eviprostat in patients with benign prostatic hyperplasia with persistent symptoms following treatment with alpha1-adrenoceptor blocker].

We examined the effectiveness of supplemental administration of Eviprostat in patients with benign prostatic hyperplasia (BPH) whose lower urinary tract symptoms (LUTS) caused by BPH were not adequately relieved by an alpha1-adrenoceptor blocker. Twenty-nine patients with insufficient improvement in the International Prostate Symptom Score (IPSS) and quality of life (QOL) score after administration of 50 mg naftopidil for 4 weeks or more received 6 tablets of Eviprostat in addition to naftopidil for another 2 weeks or more. With supplemental administration of Eviprostat, significant improvement was observed in the symptoms of incomplete emptying, daytime frequency, intermittency, weak stream, total IPSS, sum of the IPSS subscores for voiding symptoms (intermittency, weak stream and straining), sum of the IPSS subscores for storage symptoms (daytime frequency, urgency and nocturia), and QOL score. Supplemental administration of Eviprostat is therefore effective for the improvement of LUTS and QOL in BPH patients resistant to an alpha1-adrenoceptor blocker.
