Platinum-based neoadjuvant chemotherapy for locally advanced upper tract urothelial carcinoma was safe and potentially improves oncological outcomes. A carboplatin-based regimen may be used as an alternative in patients with impaired renal function.
ObjectiveThe clinical impact of neoadjuvant chemotherapy (NAC) on oncological outcomes in patients with locally advanced upper tract urothelial carcinoma (UTUC) remains unclear. We investigated the oncological outcomes of platinum-based NAC for locally advanced UTUC.ResultsOf 234 patients, 101 received NAC (NAC group) and 133 did not (Control [Ctrl] group). The regimens in the NAC group included gemcitabine and carboplatin (75%), and gemcitabine and cisplatin (21%). Pathological downstagings of the primary tumor and lymphovascular invasion were significantly improved in the NAC than in the Ctrl groups. NAC for locally advanced UTUC significantly prolonged recurrence-free and cancer-specific survival. Multivariate Cox regression analysis using an inverse probability of treatment weighted (IPTW) method showed that NAC was selected as an independent predictor for prolonged recurrence-free and cancer-specific survival. However, the influence of NAC on overall survival was not statistically significant.Materials and MethodsA total of 426 patients who underwent radical nephroureterectomy at five medical centers between January 1995 and April 2017 were examined retrospectively. Of the 426 patients, 234 were treated for a high-risk disease (stages cT3–4 or locally advanced [cN+] disease) with or without NAC. NAC regimens were selected based on eligibility of cisplatin. We retrospectively evaluated post-therapy pathological downstaging, lymphovascular invasion, and prognosis stratified by NAC use. Multivariate Cox regression analysis was performed for independent factors for prognosis.ConclusionsPlatinum-based NAC for locally advanced UTUC potentially improves oncological outcomes. Further prospective studies are needed to clarify the clinical benefit of NAC for locally advanced UTUC.
Objectives: To evaluate the relationship between frailty and lower urinary tract symptoms (LUTS), the association of frailty and LUTS remains unclear. Methods: This cross-sectional study investigated LUTS and frailty in 710 individuals (249 men and 461 women, aged ≥60 years) who participated in the Iwaki Health Promotion Project between 2014 and 2015 in Hirosaki, Japan. Parameters of frailty were compared for individuals with mild and moderate to severe symptoms of LUTS. The International Prostate Symptom Score (IPSS) and Overactive Bladder Symptom Score (OABSS) were used to evaluate LUTS. Frailty was evaluated by the frailty phenotype (FP), modified frailty index (mFI), and frailty discriminant score (FDS). The influence of frailty on LUTS was investigated by multivariate logistic regression analyses.Results: Frailty parameters of age, renal function, and lower physical activity were significantly associated with severity of IPSS and OABSS. FP and mFI were significantly associated with severity of OABSS and IPSS, respectively. The FDS was significantly associated with severity of IPSS and OABSS. FP, mFI, and FDS were significantly associated with severity of nocturia. Multivariate logistic regression analyses revealed that FDS was independently associated with the severity of IPSS, OABSS, and nocturia, whereas FP and mFI were significantly associated with the severity of nocturia alone.Conclusions: Individuals with LUTS are potentially frailer than those without LUTS.Although the influence of frailty on LUTS is different depending on the measurement tool, attention for frailty is necessary for subjects with LUTS.
ObjectiveDespite benefits of neoadjuvant chemotherapy (NAC), the adoption of guideline recommendations for NAC use in patients with muscle-invasive bladder cancer (MIBC) has been slow. We aimed to evaluate temporal trends in NAC use and oncological outcomes in a representative cohort of patients with MIBC.MethodsWe included 532 patients from 4 hospitals who underwent radical cystectomy (RC) for ≥ cT2 MIBC in 1996–2017. We retrospectively evaluated temporal changes in NAC use and progression-free and overall survival. Candidates for NAC were administered with either cisplatin- or carboplatin-based regimens. The impact of NAC on oncological outcomes was examined using multivariate Cox regression analysis with inverse probability of treatment weighting (IPTW) models.ResultsOf 532 patients, 336 underwent NAC followed by RC (NAC group) and 196 underwent RC alone (Ctrl group). NAC use significantly increased from 10% (1996–2004) to 83% (2005–2016). The number of patients administered with cisplatin- and carboplatin-based regimens was 43 and 280, respectively. Oncological outcomes in the NAC group were significantly improved compared to those in the Ctrl group. Multivariable analysis with IPTW models revealed that NAC significantly improved oncological outcomes in patients with MIBC. A nomogram for 5-year overall survival predicted 16% improvement in patients undergoing NAC.ConclusionsNAC use for MIBC increased after 2005. Platinum-based NAC for MIBC potentially improves oncological outcomes.
BackgroundPreviously reported results of a prospective, randomized placebo-controlled study showed that the pollen extract (Cernilton) significantly improved total symptoms, pain, and quality of life in patients with inflammatory prostatitis/chronic pelvic pain syndrome (CP/CPPS) without severe side effects. A phytotherapeutic agent, Eviprostat, is reportedly effective in a rat model of nonbacterial prostatitis. The aim of the present study was to compare the efficacy and safety of Eviprostat to that of the pollen extract in the management of CP/CPPS.MethodsThe patients with category III CP/CPPS were randomized to receive either oral capsules of Eviprostat (two capsules, q 8 h) or the pollen extract (two capsules, q 8 h) for 8 weeks. The primary endpoint of the study was symptomatic improvement in the NIH Chronic Prostatitis Symptom Index (NIH-CPSI). Participants were evaluated using the NIH-CPSI and the International Prostate Symptom Score (IPSS) at baseline and after 4 and 8 weeks.ResultsIn the intention-to-treat analysis, 100 men were randomly allocated to Eviprostat (n = 50) or the pollen extract (n = 50). Response (defined as a decrease in the NIH-CPSI total score by at least 25 %) in the Eviprostat group and the pollen extract group was 88.2 and 78.1 %, respectively. There was no significant difference in the total, pain, urinary, and quality of life (QOL) scores of the NIH-CPSI between the two groups at 8 weeks. This was also the case with the total, voiding, and storage symptoms of the IPSS. There were no severe adverse events observed in any patients in this study.ConclusionBoth the pollen extract and Eviprostat significantly reduced the symptoms of category III CP/CPPS without any adverse events. Eviprostat may have an identical effect on category III CP/CPPS compared the pollen extract.Trial registrationThe study was registered with the University Hospital Medical Information Network Clinical Trials Registry in Japan (UMIN000019618); registration date: 3 November 2015.
