Objectives: Nocturnal polyuria (NP) is one of the causes of nocturia that impairs quality of life. It is necessary to consider that NP is latent when the initial treatment for nocturia is unsatisfactory. Therefore, it is important to establish a treatment for NP based on the pathophysiology. We have previously reported the relationship between NP and fluctuation in blood pressure. The present study aimed to investigate the association between NP and 24‐h blood pressure fluctuations in a multicenter prospective study. Methods: This study included male patients with lower urinary tract symptoms. We categorized the patients into the nonnocturnal polyuria (non‐NP) group (≤0.33) and the NP group (>0.33) based on the nocturnal polyuria index from the frequency volume chart. We measured the 24‐h diurnal blood pressure and compared the two groups. Results: Among 90 patients, 46 in the non‐NP group and 44 in the NP group were included. There was no significant difference in the systolic and diastolic blood pressure during waking time between the two groups; however, the degree of systolic blood pressure reduction during sleep time in the NP group was significantly less than that in the non‐NP group (p = 0.039). In the multivariate analysis, systolic BP during sleep was significantly associated with NP (OR 0.970, p = 0.028). Conclusion: NP is associated with inadequate nocturnal blood pressure reduction in males, suggesting that reduction in nocturnal blood pressure may lead to improvement in nocturia.

Background: This study is part of the SNPs in Nivolumab PD‐1 inhibitor for RCC (SNiP‐RCC). Here we aimed to reveal clinical factors for tumor response, progression, and survival in nivolumab for advanced clear cell renal cell carcinoma (RCC) in Japanese patients. Methods: We included patients from 23 institutions in Japan. We evaluated the objective response, radiographic progression‐free survival (PFS), overall survival (OS), and treatment‐related grade ≥ 3 (serious adverse events [SAEs]). Results: We included 222 patients. The median age was 69 years (interquartile range 62–74 years), and 71% of the patients were male. Pancreas metastasis, lung metastases, prior cytokine therapy, and SAEs, were associated with objective response. The median PFS was 18 months. Liver metastases (hazard ratio [HR], 1.61), age ≥ 75 (HR, 0.48), previous resection of primary sites (HR, 0.47), and SAEs (HR, 0.47) were independent prognostic factors for PFS. Karnofsky Performance Status <70 (HR, 2.90), high platelets (HR, 4.48), previous resection of primary sites (HR, 0.23), and pathological grade (HR, 0.19 for grade 2 and HR, 0.12 for grade 3) were independent prognostic factors for OS. SAEs were reported in 45 (20.3%) cases. In the group of patients with prior nephrectomy, SAEs were associated with objective response, PFS, and OS. Conclusion: The SNiP‐RCC study identified clinical parameters correlated with treatment outcomes in Japanese patients with priorly treated advanced clear cell RCC undergoing nivolumab monotherapy.

Objectives: To compare overall survival between patients with metastatic renal cell carcinoma treated by cytoreductive nephrectomy and those not treated by cytoreductive nephrectomy. Methods: We retrospectively evaluated 278 patients with metastatic renal cell carcinoma treated with first‐line tyrosine kinase inhibitors between January 2008 and November 2019. Patients were divided into two groups: a cytoreductive nephrectomy group (immediate or deferred cytoreductive nephrectomy) and a group who received systemic tyrosine kinase inhibitor therapies alone without cytoreductive nephrectomy (control group). Overall survival comparisons were made in all patients in the control versus the cytoreductive nephrectomy group, the control versus the immediate cytoreductive nephrectomy group, the control versus the deferred cytoreductive nephrectomy group, and the deferred cytoreductive nephrectomy versus the immediate cytoreductive nephrectomy group. Analyses were weighted using the propensity score‐based inverse probability of treatment weighting method to adjust for group imbalances. Results: The median (range) age of the patients was 65 (59–73) years. Of the 278 patients, 132 and 146 were in the control group and the cytoreductive nephrectomy (immediate, n = 107 and deferred, n = 39) group, respectively. A significant difference was noted between the control and cytoreductive nephrectomy groups in age, clinical stage, International Metastatic Renal Cell Carcinoma Database Consortium risk factors, and the number of metastatic sites. Inverse probability of treatment weighting‐adjusted Cox regression analysis showed a significant difference in overall survival between the control and the cytoreductive nephrectomy groups and between the control and the immediate or deferred cytoreductive nephrectomy groups. However, there was no significant difference in overall survival between the immediate and the deferred cytoreductive nephrectomy groups. Conclusions: Our findings suggest that metastatic renal cell carcinoma patients undergoing cytoreductive nephrectomy are more likely to have longer overall survival than those who receive tyrosine kinase inhibitor therapy only.

Among patients in whom the T-cell response was analyzed, five patients showed a vaccine-induced T-cell response against at least one HLA class I-restricted TUMAP and two patients had T-cell responses to multiple TUMAPs. Although a phase III trial using IMA901 vaccine plus sunitinib compared to sunitinib monotherapy as first line treatment in patients with metastatic RCC has not shown survival benefit,[4] IMA901-specific CD8-positive T cell responses were recognized in some patients. Editorial Comment to Phase I/II study of multipeptide cancer vaccine IMA901 after single-dose cyclophosphamide in Japanese patients with advanced renal cell cancer with long-term follow up.

Objectives: To assess the safety and efficacy of combined therapy with interferon-alpha (INF-α) and active vitamin D3 for metastatic renal cell carcinoma (RCC). Methods: Sixteen patients with metastatic RCC were enrolled in this prospective study. All received oral alfacalcidol (1 µg once daily) and INF-α (Sumiferon; 3 million units, three times a week). The primary endpoint was the response rate (defined as complete + partial remission). Secondary endpoints were cancer-specific survival and toxicity. The median follow-up period was 17 months (range: 5–49 months). Results: The median age of the patients was 68 years (range: 41–73 years). The sites of metastases were: lung in 13 patients, bone in one, lung and bone in one, and lung, bone, and lymph nodes in one. Four patients (25%) had a partial response (PR), 10 patients (62.5%) showed no change (NC), and two patients (12.5%) had progressive disease (PD). The median cancer-specific survival time was 45 months. One patient had to discontinue vitamin D3 because of hypercalcemia. Kaplan-Meier survival analysis revealed that metastasis at the time of initial diagnosis and older than average age were significant predictors of poor survival ( P < 0.05). Conclusions: Combined treatment with INF-α and active vitamin D3 has shown to be safe and effective for metastatic RCC patients. [ABSTRACT FROM AUTHOR]
