RESUMEN
Antiresorptive agent-related osteonecrosis of the jaw (ARONJ) is a severe adverse event associated with use of bone resorption inhibitors (BRIs), such as zoledronic acid and denosumab. Based on the results of phase 3 clinical trials for BRIs, the frequency of ARONJ is reported to be 1 to 2%, but the actual frequency could be higher. We investigated 173 patients with prostate cancer with bone metastases who were treated either with zoledronic acid or denosumab at our hospital between July 2006 and June 2020. ARONJ occurred in 13 patients (8%); i.e., ten out of 159 patients (6%) who were treated with zoledronic acid, and three out of 14 patients (21%) who were treated with denosumab. Multivariate analysis showed that longer duration of BRI exposure and dental treatment before the initiation of BRI are associated with risk of ARONJ. ARONJ is associated with decreased mortality but the association is not significant. Generally, the occurrence of ARONJ may be underestimated; therefore, further studies are warranted to determine the actual frequency of ARONJ.

Radical cystectomy is an invasive procedure frequently followed by postoperative complications. Although the protocol of enhanced recovery after surgery (ERAS) is used in the postoperative course, several components of the ERAS protocol may increase the workload of medical workers. In this study, we added naldemedine tosylate only to routine postoperative management instead of using the ERAS protocol and evaluated the effect on the postoperative course of robot-assisted radical cystectomy (RARC). We retrospectively investigated 58 patients who underwent RARC from May 2015 to February 2022 at our hospital and evaluated the postoperative complications, such as ileus and urinary tract infections, and, length of hospital stay (LOS). We used naldemedine tosylate for the patients who underwent RARC after November 2019. As a result, naldemedine tosylate reduced 26.8% of postoperative complications within 30 days after the operation (pï¼0.041) and shortened LOS 8 days (pï¼0.018). Naldemesine tosylate improved the postoperative course of RARC.

Castleman's disease is a rare lymphoproliferative disease, mostly found in the mediastinum. The number of Castleman's disease cases involving the kidneys is still limited. We report a case of primary renal Castleman's disease sporadically detected during a regular health check-up as pyelonephritis with ureteral stones. In addition, computed tomography showed renal pelvic and ureteral wall thickening with paraaortic lymphadenopathy. A lymph node biopsy was performed, but it did not confirm either malignancy or Castleman's disease. The patient underwent open nephroureterectomy for diagnostic and therapeutic purposes. The pathological diagnosis was renal and retroperitoneal lymph node Castleman's disease with pyelonephritis.

We report the use of combination chemotherapy of gemcitabine (800 mg/m² on day1 and 8) and nedaplatin (60 mg/m² on day 1), including neoadjuvant therapy in four cases of squamous cell carcinoma of the urinary tract. In each case, the dose was reduced after assessing the performance status and renal function of the patient. Among the four cases, the best overall outcome was complete response in one case, partial response in two cases, and stable disease in one case. The main adverse event observed was thrombocytopenia; however, no serious adverse events were observed, and this regimen was safely administered. Therefore, we believe that this regimen could be an effective treatment option for progressive squamous cell carcinoma originating from the urinary tract.

Salvage radical prostatectomy is a postradiation treatment for patients with localized prostate cancer. In 2016, Ozu et al. (Ozu C, Aoki K, Nakamura K, Yagi Y, Muro Y, Nishiyama T, et al. The initial case report: salvage robotic assisted radical prostatectomy after heavy ion radiotherapy. Urol Case Rep 2016;7:45-7) first reported salvage robotic-assisted radical prostatectomy (sRARP) after heavy-ion radiotherapy (HIRT). Thereafter, sRARP has been performed in >100 cases. However, it is currently avoided owing to some difficulties. Herein, we report about sRARP in a 67-year-old man who received two sessions of HIRT despite some expected challenges. He was initially treated with HIRT for prostate cancer in 2009 and received the second HIRT as salvage treatment for local recurrence in 2016. In 2019, he had biochemical recurrence and underwent sRARP. There were no significant peri- or postoperative complications. Subsequently, 12 months after sRARP, hormonal therapy was introduced after the diagnosis of biochemical recurrence. The patient's prostate-specific antigen level is currently undetectable.
RESUMEN
Objective: The objective of this study is to evaluate the need for sterile gloves during cystoscopy by comparing the incidence of UTI symptoms between patients in whom the procedure is performed with non-sterile gloves with those performed with non-sterile gloves. Patients and Methods: This study had a randomized, prospective, single-blind design and included patients aged >20 years who underwent cystoscopy in either of two outpatient clinics between September 2015 and November 2021. The patients were allocated to a sterile group or a non-sterile group. Only the urologists were aware of whether or not the gloves were sterile. The patients were instructed to report any symptoms suggestive of UTI after cystoscopy. Results: A total of 1258 patients were enrolled in the sterile group and 1376 in the non-sterile group. Symptoms of UTI were reported by six patients (0.48%) in the sterile group and six (0.44%) in the non-sterile group. The between-group difference was not statistically significant (p = 0.88). Conclusion: It is not necessary to use sterile gloves during routine cystoscopy.
RESUMEN
Introduction: Small-cell carcinoma of the prostate has a poor prognosis, and treatment options for the refractory disease are unclear. Case presentation: A 68-year-old man with prostate cancer was referred to our hospital. He was treated with combined androgen blockade (bicalutamide and degarelix acetate). The disease progressed to castration-resistant prostate cancer, but with additional treatment, prostate-specific antigen levels remained below 0.02 ng/mL. However, computed tomography revealed enlarged right inguinal lymph nodes; moreover, his neuron-specific enolase levels were elevated. Histopathologic analysis of a biopsied lymph node confirmed small-cell carcinoma. After administering cytotoxic chemotherapy (etoposide plus cisplatin and amrubicin), the patient temporarily improved before relapsing. After genetic testing of the biopsy specimen revealed a BRCA2 deletion, we administered the oral PARP-2 inhibitor olaparib, which has achieved partial remission for 8 months. Conclusion: PARP-2 inhibition may improve the survival of patients with BRCA2-positive small-cell carcinoma of the prostate.
RESUMEN
Introduction: Patients with nonmetastatic but exceptionally high-risk prostate cancer are liable to have biochemical failure and may even die. Triple combination therapy, which consists of surgery, radiotherapy, and androgen-deprivation therapy, as first-line treatment, may control the disease for a long period. Case presentation: We treated a patient with super-high-risk, nonmetastatic prostate cancer, with triple combination therapy. He was biochemical relapse free at 60 months after the initiation of treatment. Conclusion: Triple combination therapy may be an option for super-high-risk, nonmetastatic prostate cancer.
