In this study, we evaluated the predictability of a modified Club Urológico Español de Tratamiento Oncológico (CUETO) scoring model and preoperative neutrophil-to-lymphocyte ratio (NLR) in patients with non-muscle invasive bladder cancer (NMIBC).

From August 2005 to May 2016, a total of 281 patients received intravesical bacillus Calmette–Guérin therapy after transurethral resection of a bladder tumor. The pathologic stage of all patients was Ta or T1. Of 281 patients, 84 (29.9%) experienced recurrence and 14 (5.0%) developed progression. The mean follow-up period was 46 months. The cut-off value for NLRs was 2.29.

One hundred-eight patients (38.4%) displayed a high NLR (> 2.29). In Kaplan–Meier curve analysis, a high NLR was associated with lower recurrence-free survival (RFS) (P < .001) and progression-free survival (PFS) (P = .002). CUETO scores were associated with RFS (P < .001), but not with PFS (P = .423). A combination of NLRs and the CUETO risk model correlated with RFS (P < .001) and PFS (P = .002). In multivariate analysis, female gender, concomitant carcinoma in situ (CIS), tumor number >3, recurrent tumors, and a high NLR were independent factors predicting recurrence (all P < .05). Concomitant CIS, recurrent tumors, and a high NLR were independent factors for predicting progression (all P < .05).

In patients with NMIBC, an NLR >2.29 was identified as a significant factor for predicting tumor recurrence and progression. Inclusion of preoperative NLR enhanced the accuracy of the CUETO model to predict disease progression.

This study aimed to evaluate the outcomes of topical steroid therapy according to potency as the first-line treatment for boys with symptomatic phimosis.

From April 2017 to March 2019, we retrospectively reviewed 45 boys with severe phi - mosis (Kikiros retractability grade 4 or 5) who presented with phimosis-related complications. During the first year of the study period, methylprednisolone aceponate (MPA, Advantan®, potent topical steroid) was administered in 24 boys. Hydrocortisone butyrate (HCB, Bandel®, moderately potent topical steroid) was administered in 21 boys in the subsequent period. Topical steroids were administered for 4–8 weeks in all patients. Success of the therapy was determined by two conditions at 3 months after therapy: achieving Kikiros grade 3 and less with disappearance of symptoms.

Of 45 boys, 35 (77.8%) achieved success of the therapy. Mean age was 46.64±22.42 months. Recurrence of phimosis with clinical complications was confirmed in three of 35 patients with initial success (8.6%) during the follow-up period. All boys with recurrence showed remission after additional topical steroid therapy. Success rate of the MPA group was higher than that of the HCB group (91.7% and 61.9% respectively, P = .029). Side effects associated with the topical steroid application were not observed in all children.

Topical steroid application is an effective and safe procedure as first-line treatment in symptomatic boys with severe phimosis. Moreover, the potency of topical steroids for the treatment of phimosis is considered a factor affecting the success rate.

Recently, controversy exists regarding the oncologic outcomes associated with the use of phosphodi esterase 5 inhibitor (PDE5i). Therefore, we attempted to verify the effect of PDE5i on biochemical recurrence (BCR) following radical prostatectomy (RP) in patients with prostate cancer (PCa). From January 2011 to May 2016, 351 patients who had undergone bilateral neurovas cular bundle saving and who were confirmed as having pT2N0M0 disease were included in the present study. We divided these patients into three groups: no PDE5i use, PDE5i use on demand , and PDE5i use for rehabilitation. We retrospectively analyzed the effect of PDE5i on BCR of PCa. Mean follow-up period was 34.4 months and mesurement of outcome was whether the patients developed BCR during regular follow-up. 25 (7.1%) patients showed BCR and univariate analysis found no significant differences in BCR between the three groups (5 (6.9%) in no PDE5i use, 8 (9.5%) in PDE5i use on demand, 12 (6.2%) in PDE5i use for rehabili tation). Multivariable analyses showed that treatment type was not a significant factor for BCR between the groups with no PDE5i use and PDE5i use (HR = 1.34 [0.49–3.70]; P = .573) and between the groups with on demand and rehabilitation use (HR = 1.37 [0.35–5.37]; P = .646). Kaplan-Meier survival curves show that there were no significant differences in PSA recurrence-free survival in three groups (P > .05). Use of PDE5is was not associated with any adverse effects on BCR after RP in patients with PCa.

To evaluate the effects of the presence of previous or synchronous non-muscle invasive bladder cancer (NMIBC) on the oncologic outcomes of radical nephroureterectomy in patients with upper tract urothelial carci­noma (UTUC). In total, 505 patients with UTUC were enrolled from four different institutions. The clinicopathologic parameters of patients with and without previous or synchronous NMIBC were compared, and Kaplan-Meier estimates and multivariate Cox regression analyses were performed. The median follow-up period was 38.4 months. In all, 408 patients had primary UTUC, 45 (8.9%) had a history of NMIBC, 59 (11.7%) had concomitant bladder cancer, and seven (1.4%) had experienced both. Tumors in patients with associated NMIBC were more commonly multifocal (P =. 001) and associ­ated with surgical margin positivity (P =. 001). Kaplan-Meier estimates revealed that previous or synchro­nous NMIBC was significantly associated with bladder recurrence (P <. 001) and locoregional recurrence/ distant metastasis (P =. 008). A multivariate Cox regression model identified previous or synchronous NMIBC as an independent predictor of bladder recurrence (P <. 001). However, the presence of previ­ous or synchronous NMIBC was not a prognostic indicator of locoregional recurrence/distant metastasis. In patients with UTUC, previous or synchronous NMIBC was significantly associated with an increased risk of cancer recurrences in the bladder after radical nephroureterectomy. The present find­ings suggest that a close monitoring should be required for the patients with previous or concomitant NMIBC.
