PURPOSE: This study aimed to clarify the efficacy and toxicity of first-line combination treatment with paclitaxel, cisplatin, and gemcitabine (PCG) for advanced/metastatic urothelial carcinoma (UC) in cisplatin-unfit patients compared with cisplatin-fit patients. METHODS: We conducted a retrospective study of patients who received first-line PCG. Using international consensus criteria, patients were classified into cisplatin-fit and -unfit groups. Cisplatin-unfit patients received PCG with adjustment of the cisplatin dose after assessing 24-hour urinary creatinine clearance, without modifying the administration interval. RESULTS: From 2008 to 2017, 50 patients received first-line PCG, of whom 30 and 20 were classified into the cisplatin-fit and -unfit groups. After a median follow-up of 15.0 months, the median overall survival (OS) and progression-free survival (PFS) were 15.0 and 9.8 months in all patients, 15.0 and 10.0 months in the cisplatin-fit group, and 13.2 and 9.3 months in the cisplatin-unfit group, respectively. There was no significant difference in OS (hazard ratio [HR]: 1.33, 95% confidence interval [CI]: 0.69-2.54) or PFS (HR: 1.38, 95% CI: 0.74-2.55) between the groups. The overall response rate and complete response rate were 58% (95% CI: 43.2-71.8) and 32% (95% CI: 19.5-46.7) in all patients, and 55% (95% CI: 31.5-76.9) and 35% (95% CI: 15.4-59.2) in the cisplatin-unfit group, respectively. The common grade 3 of 4 adverse events experienced were neutropenia (78%), followed by thrombocytopenia (56%), anemia (46%), and febrile neutropenia (16%). The 24-hour urinary creatinine clearance did not differ significantly between the groups after one, two, or three courses of PCG. CONCLUSIONS: We found no significant difference regarding OS and PFS between the cisplatin-fit patients with a full dose of cisplatin and -unfit patients with cisplatin-dose-adjusted chemotherapy. In select cisplatin-unfit patients, PCG with dose adjustment of cisplatin may be useful for treating advanced/metastatic UC without any significant adverse events or impaired renal function compared with cisplatin-fit patients with a full dose of cisplatin.

OBJECTIVES: To prospectively assess the efficacy and safety of Lactobacillus vaginal suppositories for the prevention of recurrent cystitis. METHODS: In this single-arm, open-label, phase II clinical trial, participants used vaginal suppositories containing the GAI 98322 strain of Lactobacillus crispatus for 1 year either every 2 days or three times per week. The primary end-point was the response rate, as assessed by the number of episodes of recurrent cystitis during the year of administration. The secondary end-points were the response rate, as assessed by episodes of recurrent cystitis during the 1 year after completion of the administration period; the total number of episodes of recurrent cystitis before, during and after administration; adverse events; and changes in urine bacteria and the vaginal microbiome. RESULTS: A total of 28 women were enrolled, and 21 completed the study. A total of 18 patients achieved an effective response (86%) during administration. The suppressive effects of Lactobacillus vaginal suppositories on episodes of cystitis continued up to 1 year after the last suppository was administered. There was a significant reduction in the mean number of episodes of cystitis, both during and after administration of Lactobacillus vaginal suppositories. No treatment-related adverse events were observed. Amplicon sequencing analysis of the vaginal microbiome showed that Lactobacillus species colonized the vagina during the periods when episodes of cystitis were absent. CONCLUSIONS: Vaginal suppositories containing the GAI 98322 strain of Lactobacillus crispatus effectively prevent episodes of recurrent cystitis, both during administration and for at least 1 year after administration.

BACKGROUND: The aim of this study is to compare the perioperative outcomes and learning curves between intracorporeal and extracorporeal urinary diversion at our medium-sized institution. METHODS: Between January 2018 and September 2020, a single surgeon at our institution performed 46 consecutive robot-assisted radical cystectomies with ileal conduit. We compared the perioperative outcomes between patients who underwent intracorporeal versus extracorporeal urinary diversion. We also investigated learning curves for the first and last 10 patients in each group. RESULTS: The extracorporeal group had shorter overall operative time (P = 0.003) and urinary diversion time (P < 0.0001) than the intracorporeal group. The intracorporeal group had shorter length of hospital stay (P = 0.02). There was no difference in complication and readmission rates. The extracorporeal group demonstrated no difference between the first and last 10 patients for overall operative time or time for cystectomy, lymph node dissection, or urinary diversion. However, the intracorporeal group had shorter urinary diversion time for the last 10 patients compared with the first 10 patients. The first 10 patients in the extracorporeal group had shorter overall operative time than the first 10 in the intracorporeal group, but there was no difference for the last 10 patients. CONCLUSIONS: Intracorporeal urinary diversion requires longer overall operative time than extracorporeal diversion for the first 10 patients, due to longer urinary diversion time. However, there is no difference in overall operative time for the last 10 patients. The benefit of intracorporeal over extracorporeal urinary diversion was not confirmed at our medium-sized institution.

We report a 62-year-old male with metastatic fumarate hydratase-deficient renal cell carcinoma (FH-deficient RCC) without fumarate hydratase (FH) mutation (FH-deficient-like RCC). The International Metastatic RCC Database Consortium risk score was intermediate, and immunotherapy with nivolumab and ipilimumab (Ipi/ Nivo) was initiated. Four cycles of Ipi/Nivo and 5 cycles of nivolumab resulted in a complete response of the metastases. Hypophysitis occurred as an immune-related adverse event after four cycles of Ipi/Nivo. The prognosis of patients with FH-deficient RCC is generally poor. Few reports of FH-deficient RCC successfully treated with Ipi/Nivo have been published. Ipi/Nivo can be effective for treating FH-deficient RCC.

BACKGROUND: The advantages of photodynamic diagnostic technology using 5-aminolevulinic acid (ALA-PDD) have been established. The aim of this prospective cohort study was to evaluate the usefulness of ALA-PDD to diagnose upper tract urothelial carcinoma (UT-UC) using the Olympus VISERA ELITE video system. METHODS: We carried out a prospective, interventional, non-randomized, non-contrast and open label cohort pilot study that involved patients who underwent ureterorenoscopy (URS) to detect UT-UC. 5-aminolevulinic acid hydrochloride was orally administered before URS. The observational results and pathological diagnosis with ALA-PDD and traditional white light methods were compared, and the proportion of positive subjects and specimens were calculated. RESULTS: A total of 20 patients were enrolled and one patient who had multiple bladder tumors did not undergo URS. Fifteen of 19 patients were pathologically diagnosed with UT-UC and of these 11 (73.3%) were ALA-PDD positive. Fourteen of 19 patients were ALA-PDD positive and of these 11 were pathologically diagnosed with UC. For the 92 biopsy specimens that were malignant or benign, the sensitivity for both traditional white light observation and ALA-PDD was the same at 62.5%, whereas the specificities were 73.1% and 67.3%, respectively. Of the 38 specimens that were randomly biopsied without any abnormality under examination by both white light and ALA-PDD, 11 specimens (28.9%) from 5 patients were diagnosed with high grade UC. In contrast, four specimens from 4 patients, which were negative in traditional white light observation but positive in ALA-PDD, were diagnosed with carcinoma in situ (CIS). CONCLUSIONS: Our results suggest that ALA-PDD using VISERA ELITE is not sufficiently applicable for UT-UC. Nevertheless, it might be better particularly for CIS than white light and superior results would be obtained using VISERA ELITE II video system. TRIAL REGISTRATION: The present clinical study was approved by the Okayama University Institutional Review Board prior to study initiation (Application no.: RIN 1803-002) and was registered with the UMIN Clinical Trials Registry (UMIN-CTR), Japan (Accession no.: UMIN000031205).

PURPOSE: The aim of this study was to compare the prognostic value of pretreatment inflammation-based scoring systems in terms of overall survival (OS) and progression-free survival (PFS) in patients with germ cell tumors (GCTs) receiving bleomycin, etoposide, and cisplatin (BEP) chemotherapy. MATERIALS AND METHODS: We evaluated 63 patients with GCTs retrospectively. The Glasgow prognostic score (GPS), neutrophil-to-lymphocyte ratio, prognostic index, platelet-to-lymphocyte ratio (PLR), prognostic nutritional index (PNI), systemic immune-inflammation index, and albumin-to-globulin ratio (AGR) were measured in all patients before chemotherapy. To assess the predictive ability of each scoring system, areas under the receiver operating characteristic curve were calculated, and multivariate analysis was performed to identify associations between the predictive scores and OS. RESULTS: Of all the inflammation-based scoring systems, the GPS had the greatest area under the curve (0.847) for predicting OS, followed by the PNI (0.829) and AGR (0.810). Kaplan-Meier analyses revealed that the GPS, PNI, and AGR were significantly associated with OS, whereas the GPS, PLR, and PNI were significantly associated with PFS. In the multivariate analysis, the GPS was an independent predictor of OS and PFS. CONCLUSIONS: We demonstrated that the GPS was the most valuable biomarker of OS and PFS in patients with GCTs.

CONTEXT: Androgen deprivation therapy is the mainstay treatment of metastatic prostate cancer, achieved mainly by gonadotropin-releasing hormone (GnRH) agonists or antagonists. OBJECTIVE: To investigate the differential impact of GnRH agonists and antagonists on clinical safety and oncologic outcomes. EVIDENCE ACQUISITION: This meta-analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. A literature search using the electronic databases (MEDLINE, Web of Science, Cochrane Library, and Scopus) included randomized controlled trials comparing the clinical safety and oncologic outcomes of GnRH agonists and antagonists. The endpoints of interest were the following: (1) treatment-related adverse effects (AEs), (2) prostate-specific antigen (PSA) progression, and (3) overall mortality. The relative risk (RR) was used as the summary statistic, and results were reported with 95% confidence intervals (CIs). EVIDENCE SYNTHESIS: Eight clinical trials (20 published studies) comprising 2632 men met our inclusion criteria; of them, 1646 received GnRH antagonist and 986 had GnRH agonist. Treatment-emerging AEs occurred in 73% patients in the GnRH antagonist group and 68% in the GnRH agonist group (RR: 1.10, 95% CI: 1.04-1.15). Serious AEs occurred in 9.8% of the GnRH antagonist and 11% of the GnRH agonist group (RR: 0.92, 95% CI: 0.73-1.17). Antagonists were associated with higher injection site reaction rates (38%) than agonists (4.8%). GnRH antagonist was associated with fewer cardiovascular events (RR: 0.52, 95% CI: 0.34-0.80). There was no significant difference in PSA progression, but GnRH antagonist was associated with lower overall mortality rates than GnRH agonists (RR: 0.48, 95% CI: 0.26-0.90, p = 0.02). CONCLUSIONS: Existing data indicate that GnRH antagonist use is associated with significantly lower overall mortality and cardiovascular events as compared with agonists. These findings should be interpreted with caution owing to the short follow-up duration and assessment of cardiovascular events as secondary endpoints in the included trials. Further studies are needed to validate or refute these observations. Injection site reactions were significantly higher in the GnRH antagonist group. PATIENT SUMMARY: Gonadotropin-releasing hormone (GnRH) antagonist is associated with lower death rates and cardiovascular events than GnRH agonists, based on the data from trials with short follow-up duration. GnRH agonists are associated with lower adverse events, such as decreased libido, hot flushes, erectile dysfunction, back pain, weight gain, constipation, and injection site reactions. There were no significant differences in prostate-specific antigen progression or fatigue.

骨盤臓器脱に対する治療として, 2010年に経腟メッシュ手術が, 2014年に腹腔鏡下仙骨膣固定術が保険収載され, 泌尿器科医が骨盤臓器脱に対する治療を行うことも一般的になってきている.

2020年4月の診療報酬改定により, 新たにロボット支援腹腔鏡下仙骨膣固定術が保険収載された. 腹腔鏡下仙骨膣固定術は, 正確な剥離操作を要し, 深部での縫合結紮操作を多用する手術であることなど, 良性疾患に対する手術でありながら手技の難易度が比較的高い術式であると考えられる. これに対して手術支援ロボットを用いることで, 手術の難易度が低減されること, 手術成績が向上することが期待される.

当院でも2020年8月よりロボット支援下仙骨膣固定術を導入した. ロボット支援下仙骨膣固定術のメリットやデメリット, 導入の意義などについて, 手術導入に向けた取り組みについて述べる.
