[TYPICAL TYPE CYSTITIS GLANDULARIS PRESENTING URINARY RETENTION IN A YOUNG MAN: ADJUVANT THERAPY USING ORAL CYCLOOXYGENASE-2 INHIBITOR: A CASE REPORT].

A 31-year-old man was referred to our hospital with urinary retention. Cystoscopy revealed multiple edematous papillary tumors on the bladder trigone and neck, which were removed by transurethral resection. The pathological diagnosis was typical type cystitis glandularis. This relapsed six months after surgery and transurethral resection was repeated. Because immunohistochemical findings revealed positive epithelial cyclooxygenase-2 (COX-2) signals, we prescribed an oral COX-2 inhibitor. The tumor revealed shrinkage for six months after medication.

[ISOLATED METASTASIS OF RENAL CELL CARCINOMA TO THE LARYNX: A CASE REPORT].

A 55-year-old man underwent right radical nephrectomy after the diagnosis of right renal cell carcinoma (RCC). He did not show any relapse or metastasis for 3 years and 5 months after surgery. He was admitted to the hospital in April 2014 with a throat discomfort. Laryngoscopy revealed a 5 mm supraglottic mass. The tumor was locally excised and pathology revealed metastatic RCC. While RCC frequently metastasizes to the lungs, bones, lymph nodes, and brain, an isolated metastasis of RCC to the larynx is an extremely rare event. We report a case of isolated RCC metastasis to the supraglottic larynx 3 years and 5 months after radical nephrectomy.

Serum G-CSF May Be a More Valuable Biomarker than Image Evaluation in G-CSF-Producing Urothelial Carcinoma: A Case Report.

Granulocyte colony-stimulating factor (G-CSF)-producing urothelial carcinomas (UCs) are rare and have a poor prognosis. According to the literature, treatment for G-CSF-producing UCs is very difficult. We experienced 2 cases of UC presenting with leukocytosis. In these cases, serum G-CSF levels were higher than the reference value with leukocytosis at diagnosis, and the resected specimens were positive for anti-G-CSF immunostaining. One case had a good prognosis and the other case died after 9 months from diagnosis. A change in serum G-CSF levels was reportedly an effective tumor marker in several reports. In the present cases, evaluation of serum G-CSF levels was found to be more sensitive than computerized tomography. The treatment and outcomes of UC-producing G-CSFs and the efficacy of serum G-CSF as a tumor marker are discussed based on our cases and a review of the literature.

A phase III multicenter, randomized, controlled study of combined androgen blockade with versus without zoledronic acid in prostate cancer patients with metastatic bone disease: results of the ZAPCA trial.

OBJECTIVE: To examine the antitumor activity of zoledronic acid (ZA) combined with androgen deprivation therapy (ADT) for men with treatment-naive prostate cancer and bone metastasis. METHODS: We enrolled 227 men with treatment-naive prostate cancer and bone metastasis. Participants were randomly assigned (1:1 ratio) to receive combined androgen blockade alone (CAB group) or ZA with combined androgen blockade (CZ group). Time to treatment failure (TTTF), time to the first skeletal-related event (TTfSRE), and overall survival (OS) rates were estimated using the Kaplan-Meier method. Hazard ratios (HRs) were calculated using the Cox proportional hazards model. Median follow-up duration was 41.5 months. RESULTS: Median TTTFs were 12.4 and 9.7 months for the CZ and CAB groups, respectively (HR 0.75; 95 % CI 0.57-1.00; p = 0.051). For men with baseline prostate-specific antigen levels <200 ng/mL, median TTTFs were 23.7 and 9.8 months for the CZ and CAB groups, respectively (HR 0.58; 95 % CI 0.35-0.93; p = 0.023). Median TTfSREs were 64.7 and 45.9 months for the CZ and CAB groups, respectively (HR 0.58; 95 % CI 0.38-0.88; p = 0.009). OS was similar between the groups. CONCLUSIONS: This study failed to demonstrate that combined use of ZA and ADT significantly prolonged TTTF in men with treatment-naive prostate cancer and bone metastasis. However, it generates a new hypothesis that the combined therapy could delay the development of castration resistance in a subgroup of patients with low baseline prostate-specific antigen values <200 ng/mL. The treatment also significantly prolonged TTfSRE but did not affect OS.

Providing prostate cancer survivorship care in Japan: Implications from the USA care model.

Despite an increasing number of prostate cancer survivors in Japan, the current delivery of prostate cancer survivorship care is insufficient and lacks a multidisciplinary approach. We carried out a study to characterize prostate cancer survivorship care in Japan, examine the Japanese workforce available to deliver survivorship care, introduce a conceptual framework for survivorship and identify opportunities to improve Japanese survivorship care. We systematically searched PubMed for prostate cancer survivorship care studies, including those from Japan. We also searched the internet for prostate cancer guidelines relevant to survivorship care. We found 392 articles, of which 71 were relevant, read in detail and reported here. In Japan, survivorship care is mostly provided by urologists. Primary care as a specialty does not exist in Japan, and there are no independent nurse practitioners or physician assistants to assist with survivorship care. Japanese quality of life studies characterize the long-term effects of prostate cancer treatment, but routine use of patient-reported outcomes is not common in Japan. In the USA, in light of a growing comprehensive awareness of challenges facing survivors and their providers, the American Cancer Society prostate cancer survivorship care guidelines serve as a tool for optimizing the management of long-term treatment effects and coordination of care. In order to deliver high-quality survivorship care in Japan, urologists need to establish collaborations with other disciplines within the delivery system. A multidisciplinary guideline for prostate cancer survivorship care in Japan appears warranted.

[Inflammatory Myofibroblastic Tumor of the Bladder : A Case Report].

A 39-year-old female visited our hospital because of a bladder tumor. Computed tomography and magnetic resonance imaging showed a retrovesical tumor in dome of the bladder. Cystoscopy showed edematous inflammatory changes of the mucosa of the bladder wall. We diagnosed her with urachal carcinoma from cystoscopy finding and image inspections. She received partial cystectomy with pelvic lymphadenectomy. Histopathological examination revealed inflammatory myofibroblastic tumor because these specimens presented positive for anaplastic lymphoma kinase in immunohistochemical studies. She has been followed up for 16 months without any evidence of local recurrence.

Serum luteinizing hormone concentration is significantly associated with recovery of urinary function after radical prostatectomy.

OBJECTIVE: To perform a longitudinal investigation of the correlation between functional recovery and sex hormone concentrations after radical prostatectomy (RP). PATIENTS AND METHODS: A total of 72 consecutive patients undergoing RP between January 2012 and June 2013 were prospectively included and serially followed after surgery for comparative analysis. Their luteinizing hormone (LH) and total testosterone (TT) concentrations were measured before surgery and 3 and 12 months after surgery. They also filled out a health-related quality of life questionnaire before and at 1, 3, 6 and 12 months after surgery. RESULTS: The mean LH concentration increased from 4.28 U/L at baseline to 5.53 U/L at 3 months and remained high at 12 months after RP (both P < 0.001). There were no significant changes in the TT concentration after RP. LH at baseline was negatively correlated with the urinary function (UF) score at 3 and 12 months after RP (P = 0.030 and 0.032, respectively). After RP, subjects with high baseline LH (n = 37) were more likely than those with low LH concentrations to report lower UF scores (P = 0.014). Multivariate analysis of variance in an interaction of time × LH concentration for UF scores indicated a significant relationship between changes in UF score and LH concentration (P = 0.004). CONCLUSIONS: Radical prostatectomy affects sex hormones by increasing LH concentrations, while TT concentrations remain stable after surgery. Baseline LH concentrations are significantly associated with the recovery of urinary outcomes after RP.

Transdifferentiation of Small Cell Carcinoma of the Urinary Bladder from Urothelial Carcinoma after Transurethral Resection of a Bladder Tumor, Intravesical Bacillus Calmette-Guerin Instillation, and Chemotherapy: A Case Report.

A 73-year-old male underwent transurethral resection of a bladder tumor in August 2010 and April 2011. Pathological examination revealed urothelial carcinoma. After the surgery, chemotherapy and intravesical Bacillus Calmette-Guerin instillation were performed. In September 2014, he once again underwent transurethral resection of the bladder tumor for recurrence, and was again diagnosed with urothelial carcinoma, pT2, by pathological examination. After neoadjuvant chemotherapy, radical cystectomy for tumor recurrence was performed. Pathological examination at this time revealed small cell carcinoma, pT3N0. It is rare for urothelial carcinoma to change to small cell carcinoma, and the mechanism and cause of this change are still unknown. In this case report, we discuss what causes small cell carcinoma of the urinary bladder and review the literature regarding its origin.

[Total penectomy for corpus cavernosum abscess: a case report].

Abscess of corpus cavernosum penis is a rare infection condition. A 69-year-old-man was referred toour hospital with gradual development of penis swelling. T2-weighted magnetic resonance imaging of the pelvis showed abscess formation in the corpus cavernosum. There was no apparent cause of his penile abscess from either history or clinical examination. Open drainage improved his clinical symptoms transiently. However, severe penile pain relapsed, and abscess progressively extended in the corpus cavernosum and spongiosum, necessitating total penectomy. The surgical specimen revealed intensive inflammation and his condition improved immediately after penectomy.

Long-term quality of life after radical prostatectomy: 8-year longitudinal study in Japan.

OBJECTIVES: To assess long-term health-related quality of life in patients undergoing radical prostatectomy. METHODS: A total of 120 patients with at least 5 years of follow up after radical prostatectomy were included in the present study. Health-related quality of life outcomes were assessed using three questionnaires, the Short Form 36-Item Health Survey, the University of California, Los Angeles Prostate Cancer Index and the International Prostate Symptom Score. RESULTS: A total of 91 patients (73%) responded at a median follow-up time of 102 months (range 85-123 months). Among general health-related quality of life domains, mental and role composite summary score remained stable throughout the follow-up period. At the final survey, no significant differences were observed in any of the domains compared with the age-matched average score of the Japanese population. Although the slight decrease in urinary function scores and International Prostate Symptom Score beyond 5 years postoperatively compared with 5 years, the differences were not significant. The sexual function summary score showed a substantially lower score just after radical prostatectomy and remained at a deteriorated level (P < 0.001). Responders at the final survey were more likely to report favorable general, urinary and sexual outcomes at 60 months compared with non-responders. CONCLUSIONS: When taking age-related changes into account, general health-related quality of life seems to remain stable in the long term after radical prostatectomy: patients with favorable health-related quality of life outcomes during the first 5 years after radical prostatectomy maintain favorable outcomes thereafter.

Low-dose maintenance gemcitabine-carboplatin chemotherapy could be an alternative to continuous standard chemotherapy for patients with metastatic urothelial carcinoma.

OBJECTIVES: To examine whether low-dose maintenance gemcitabine-carboplatin chemotherapy is beneficial for patients with metastatic urothelial carcinoma. METHODS: We retrospectively reviewed the records of 36 patients with metastatic urothelial carcinoma who received first-line chemotherapy (gemcitabine/cisplatin, gemcitabine/carboplatin, or methotrexate/vinblastine/adriamycin/cisplatin) between 2006 and 2012. Those who had responded, but were unable to tolerate ongoing first-line chemotherapy, had been switched to low-dose maintenance chemotherapy consisting of 1 g/m(2) of gemcitabine and area under the curve 2-4 of carboplatin given on day 1 of a 6-week cycle, and were continued unless disease progression was seen. RESULTS: After a median of three cycles of first-line chemotherapy, 17 patients had been switched to low-dose maintenance chemotherapy. The median age was 70 years (range 56-79 years), and 12 patients (70.6%) had renal dysfunction (creatinine clearance <60 mL/min). The median number of cycles of low-dose maintenance chemotherapy was six (range 2-22), and the median survival time from initiation of first-line chemotherapy was 12 months (range 4-32 months). Adverse events requiring hospitalization were seen in three patients, but all of them recovered within a few days with conservative treatment. Seven patients discontinued within 9 months, whereas 10 patients continued on low-dose maintenance chemotherapy for ≥9 months. Patients with only lymph node metastases or who had a good response to previous first-line chemotherapy were likely to be able to continue low-dose maintenance chemotherapy. CONCLUSIONS: Low-dose maintenance gemcitabine-carboplatin chemotherapy might represent an alternative for patients with metastatic urothelial carcinoma not tolerating continuous first-line standard chemotherapy regimens.

[Upper tract urothelial carcinoma associated with giant hydronephrosis due to ligation of a ureter: a case report].

A 73-year-old woman was referred to our hospital with a complaint of left lumbar backache. Computed tomography (CT) revealed left giant hydronephrosis containing high-density fluid suspected of hemorrhage in the renal pelvis and swelling of cervical and mediastinal lymph nodes. Positron emission tomography (PET)-CT showed a small high uptake lesion in the left kidney parenchyma, and cervical and mediastinal lymph nodes. Percutaneous pelvic puncture yielded discharge of hemorrhagic fluid with negative cytology. Preoperative diagnosis was left giant hydronephrosis due to ligation of a left ureter at uterine myomectomy 43 years ago with renal hemorrhage caused by recent back injury, and cervical and mediastinal lymph node involvement of unknown origin. Because severe lumbar backache persisted, we performed palliative left nephrectomy and biopsy of cervical lymph nodes. The pathological diagnosis was invasive urothelial carcinoma with squamous differentiation and lymph node involvement.

Impact of prostate size on urinary quality of life scores after open radical prostatectomy: a single-center experience.

OBJECTIVE: The aim of this study was to assess the effects of prostate size on long-term health-related quality of life (HRQoL) and functional outcomes after radical prostatectomy (RP). MATERIAL AND METHODS: A total of 207 consecutive patients who underwent RP for localized prostate cancer was stratified by pathological prostate gland weight into group 1, patients with prostate glands weighing less than 30 g; group 2, those with prostates weighing 30-50 g; and group 3, those with prostates weighing more than 50 g. Urinary HRQoL was assessed before surgery and at 1, 3, 6, 12, 18, 24, 36, 48 and 60 months after RP using a Japanese version of the Expanded Prostate Cancer Index Composite (EPIC) questionnaire. RESULTS: Baseline urinary function was significantly (p < 0.05) reduced in patients with the largest glands (group 3), as demonstrated by EPIC urinary domain summary and subscale scores, including scores for urinary bother, irritation and obstruction, compared with patients with smaller glands (groups 1 and 2). At follow-up ranging from 18 to 36 months, patients in group 3 had improved EPIC urinary domain summary and subscale scores, including scores for urinary irritation and obstruction and urinary bother subscale scores, compared with their baseline scores (p < 0.05). CONCLUSIONS: In patients with large prostate glands, postoperative improvement was observed in HRQoL and functional outcome after RP. Thus, RP may be beneficial in patients with large prostates.

Salvage chemotherapy with docetaxel, ifosfamide and nedaplatin (DIN) for patients with advanced germ cell tumors: a preliminary report.

OBJECTIVE: We investigated the efficacy and toxicity of a docetaxel, ifosfamide and nedaplatin regimen as salvage therapy for patients with advanced testicular germ cell tumor. METHODS: Eleven patients with advanced germ cell tumor refractory or relapsed after cisplatin-based chemotherapy were treated using docetaxel, ifosfamide and nedaplatin. The docetaxel, ifosfamide and nedaplatin regimen comprised docetaxel (75 mg/m(2)) on Day 1, ifosfamide (2 g/m(2)) on Days 1-3 and nedaplatin (75 mg/m(2)) on Day 2 of a 3-week cycle. RESULTS: Ten (91%) of the 11 patients achieved favorable responses, including complete response in one case and partial response in nine cases. Nine (81%) of the 11 patients have continued to show no evidence of disease after docetaxel, ifosfamide and nedaplatin therapy followed by subsequent surgical resection, with a median follow-up period of 52 months. One patient died of the disease 3 months after completing docetaxel, ifosfamide and nedaplatin chemotherapy. One patient was lost to follow-up with a status of alive with disease. Ten (91%) of the 11 patients developed Grade 4 leukopenia, which was managed using granulocyte colony-stimulating factor. No patients developed sensory neuropathy or renal dysfunction. CONCLUSIONS: The docetaxel, ifosfamide and nedaplatin regimen was efficacious and well-tolerated as salvage chemotherapy for patients with advanced germ cell tumor.

Prospective randomized phase II trial of a single early intravesical instillation of pirarubicin (THP) in the prevention of bladder recurrence after nephroureterectomy for upper urinary tract urothelial carcinoma: the THP Monotherapy Study Group Trial.

PURPOSE: We evaluated the efficacy of a single early intravesical instillation of pirarubicin (THP) in the prevention of bladder recurrence after nephroureterectomy for upper urinary tract urothelial carcinoma (UUT-UC). PATIENTS AND METHODS: From December 2005 to November 2008, 77 patients clinically diagnosed with UUT-UC from 11 institutions participating in the Tohoku Urological Evidence-Based Medicine Study Group were preoperatively enrolled in this study. Patients were randomly assigned to receive or not receive a single instillation of THP (30 mg in 30 mL of saline) into the bladder within 48 hours after nephroureterectomy. Cystoscopy and urinary cytology were repeated every 3 months for 2 years or until the occurrence of first bladder recurrence. RESULTS: Seventy-two patients were evaluable for efficacy analysis, 21 of whom had a subsequent bladder recurrence. Significantly fewer patients who received THP had a recurrence compared with the control group (16.9% at 1 year and 16.9% at 2 years in the THP group v 31.8% at 1 year and 42.2% at 2 years in the control group; log-rank P = .025). No remarkable adverse events were observed in the THP-treated group. Based on multivariate analysis, THP instillation (hazard rate [HR], 0.26; 95% CI, 0.07 to 0.91; P = .035) and open surgery (HR, 0.28; 95% CI, 0.09 to 0.84; P = .024) were independently predictive of a reduced incidence of bladder recurrence. CONCLUSION: In this prospective randomized phase II study, a single intravesical instillation of THP seemed to reduce bladder recurrence after nephroureterectomy. A phase III, large-scale, multicenter study is needed to confirm these observations.

Extraperitoneal laparoscopic retroperitoneal lymph node dissection after chemotherapy for nonseminomatous testicular germ-cell tumor: surgical and oncological outcomes.

PURPOSE: To assess the surgical and oncological outcomes of laparoscopic retroperitoneal lymph node dissection (RPLND) after chemotherapy. METHODS: Twenty patients with metastatic nonseminomatous testicular germ-cell tumor underwent extraperitoneal laparoscopic RPLND after chemotherapy. The procedure was not indicated for patients with a pre-chemotherapy mass larger than 5 cm. Morbidity and oncological outcome were reviewed retrospectively. Surgical complications were graded according to the Clavien classification system. RESULTS: Laparoscopic RPLND was completed in all patients, and there was no conversion to open surgery. The median operating time was 223 min (range, 137-399 min). The median blood loss was 20 ml (range, 10-520 ml). There were no intraoperative complications. Postoperatively, 4 patients (20 %) had prolonged lymphorrhea (grade I) and 9 (45 %) had chyle leakage (grade I). Histological examination of the residual mass revealed necrosis in 16 (80 %) and the presence of teratoma with/without viable tumor in 4 (20 %). With a median follow-up of 45 months (range, 24-112), no patient has had disease recurrence. Normal antegrade ejaculation was preserved in all of the 14 patients studied. CONCLUSIONS: Extraperitoneal laparoscopic RPLND can be performed with acceptable morbidity and excellent cancer control in select patients. Surgeons should be aware of relatively high incidence of chyle leakage following this procedure.
