Efficacy of early ureteral ligation on prevention of intravesical recurrence after radical nephroureterectomy for upper urinary tract urothelial carcinoma: a prospective single-arm multicenter clinical trial.

OBJECTIVE: The rate of intravesical recurrence after radical nephroureterectomy for upper urinary tract urothelial carcinoma is high. Seeding upper urinary tract urothelial carcinoma cells onto the damaged bladder wall is considered to be one of the causes of intravesical recurrence after radical nephroureterectomy. We evaluated the utility of early ureteral ligation in preventing the intravesical recurrence. METHODS: This prospective single-arm clinical trial included patients who underwent radical nephroureterectomy for upper urinary tract urothelial carcinoma in the Tohoku Urological Evidence-Based Medicine Study Group between 2012 and 2013. Early ureteral ligation was defined as ligation of the ureter as quickly as possible after expanding the retroperitoneal space. A historical control was extracted from 454 patients who underwent radical nephroureterectomy in the same group, using propensity score-matched analysis. Intravesical recurrence-free survival rates were analyzed using Kaplan-Meier curves. Factors predicting intravesical recurrence were assessed using multivariate analyses. RESULTS: Seventy-four patients underwent early ureteral ligation. Seventeen (23%) patients had intravesical recurrence with a median follow-up period of 24 months. The 1- and 2-year intravesical recurrence-free survival rates in the early ureteral ligation group were 81% and 76%, and in the control group 75% and 63%, respectively (P = 0.160). In patients with renal pelvic cancer, the 1- and 2-year intravesical recurrence-free survival rates in the early ureteral ligation group were 89% and 86%, but in the control group 74% and 64%, respectively (P = 0.025). However, intravesical recurrence-free survival rates were similar in patients with ureteral cancer. Multivariate analyses of a subset of patients with renal pelvic cancer identified early ureteral ligation as an independent predictor of intravesical recurrence. CONCLUSIONS: Early ureteral ligation decreases the rate of intravesical recurrence after radical nephroureterectomy in patients with renal pelvic cancer. Thus, early ureteral ligation might help in prevention of intravesical recurrence for renal pelvic cancer.

Clinical implications of intravesical recurrence after radical nephroureterectomy for upper urinary tract urothelial carcinoma.

OBJECTIVES: To characterize the site and clinical implications of intravesical recurrence after radical nephroureterectomy for upper urinary tract urothelial carcinoma. METHODS: Patients who underwent radical nephroureterectomy for upper urinary tract urothelial carcinoma between 2000 and 2011 at 12 institutions participating in the Tohoku Urological Evidence-Based Medicine Study Group were included in the present study. Those who underwent prior or simultaneous radical cystectomy were excluded. The site of intravesical recurrence was investigated, and the survival curves after radical nephroureterectomy were analyzed retrospectively using the Kaplan-Meier method. Multivariate analyses of factors predicting survival were carried out. RESULTS: A total of 534 patients were eligible for the present study. With a median follow up of 47 months, 205 patients (38.4%) had intravesical recurrence. The intravesical recurrence-free survival rates at 1, 2, and 5 years were 74.6%, 62.5% and 56.3%, respectively. In a subset of 137 patients with intravesical recurrence who did not have bladder cancer before or at the diagnosis of upper urinary tract urothelial carcinoma, the most frequent site of intravesical recurrence was around the cystotomy (52.6%), followed by at the posterior wall (39.4%) and at the bladder neck (35.8%). A total of 36 patients (17.6%) developed muscle-invasive bladder cancer after radical nephroureterectomy. On multivariate analyses for the subset of patients with non-muscle invasive (≤pT1) upper urinary tract urothelial carcinoma, intravesical recurrence was an independent predictor of cancer-specific survival (HR 4.27, P = 0.016) and overall survival (HR 3.00, P = 0.018). CONCLUSIONS: Most intravesical recurrences occur around the site of bladder mucosal injury within 1 year after radical nephroureterectomy, providing important insight into the mechanism of intravesical recurrence. Intravesical recurrence after radical nephroureterectomy had an impact on oncological outcomes of patients with non-muscle invasive upper urinary tract urothelial carcinoma.

Renal epithelioid angiomyolipoma with malignant features: Histological evaluation and novel immunohistochemical findings.

Renal epithelioid angiomyolipoma (EAML) is a potentially malignant tumor type whose characteristics and biomarkers predictive of malignant behavior have not been elucidated. Here, we report three cases of renal EAML with malignant features but without histories of tuberous sclerosis complex. Case 1 involved a 29-year-old man with a 12-cm solid mass in the right kidney who underwent radical right nephrectomy. Case 2 involved a 22-year-old woman with a retroperitoneal mass who underwent radical right nephrectomy and retroperitoneal tumorectomy. Local recurrence was detected 7 years post-surgery. Case 3 involved a 23-year-old man with a 14-cm solid mass in the left kidney who underwent radical left nephrectomy. Microscopically, the tumors in all cases demonstrated proliferation of epithelioid cells with atypia, mitotic activity, necrosis, hemorrhage, and vascular invasion. Epithelioid cells in all cases were immunohistochemically positive for melanocytic and myoid markers and weakly positive for E-cadherin and ß-catenin. Immunohistochemistry revealed activation of the mammalian target of rapamycin pathway. Here, we report the morphological and immunohistochemical features of clinically or histologically malignant renal EAML.

Intravesical seeding of upper urinary tract urothelial carcinoma cells during nephroureterectomy: an exploratory analysis from the THPMG trial.

OBJECTIVE: The Pirarubicin Monotherapy Study Group trial was a randomized Phase II study that evaluated the efficacy of intravesical instillation of pirarubicin in the prevention of bladder recurrence after nephroureterectomy for upper urinary tract urothelial carcinoma. This study conducted further analysis of the Pirarubicin Monotherapy Study Group cohort, focusing on intravesical seeding of cancer cells. METHODS: Using the data from the Pirarubicin Monotherapy Study Group trial, bladder recurrence-free survival rates and factors associated with bladder recurrence in the control group were analyzed. RESULTS: Of 36 patients in the control group, 14 with positive urine cytology had more frequent recurrence when compared with the 22 patients with negative cytology (P = 0.004). Based on the multivariate analysis in the control group, voided urine cytology was an independent predictive factor of bladder recurrence (hazard ratio, 5.54; 95% confidence interval 1.12-27.5; P = 0.036). Of 72 patients in the Pirarubicin Monotherapy Study Group trial, 31 had positive urine cytology. Among the 31 patients, 17 patients who received pirarubicin instillation had fewer recurrences when compared with 14 patients who received control treatment (P = 0.0001). On multivariate analysis, pirarubicin instillation was an independent predictor of better recurrence-free survival rates in the patients with positive urine cytology (hazard ratio, 0.02; 95% confidence interval, 0.00-0.53; P = 0.018). Of 21 patients with bladder recurrence, 17 had recurrent tumor around cystotomy or in the bladder neck compromised by the urethral catheter, supporting the notion that tumor cells seeded in the injured urothelium. CONCLUSIONS: Intravesical instillation of pirarubicin immediately after nephroureterectomy significantly reduced the bladder recurrence rate in patients with positive voided urine cytology. The results suggest that intravesical seeding of upper urinary tract urothelial carcinoma occurs during nephroureterectomy.

Real-world outcomes of patients with renal cell carcinoma, surgically treated at regional hospitals, based on a prospective long-term survey of the pre-robotic era.

PURPOSE: Renal cancer surgery is frequently performed in small regional hospitals in Japan. This study evaluated the outcomes of renal cancer surgery, comparing results from the pre-robotic surgery era with those obtained with robotic surgery. METHODS: This prospective cohort study was conducted on patients who underwent renal cancer surgery between 2008 and 2013 at 14 hospitals, comprising 13 regional hospitals and a university hospital, registered in the Tohoku Urological Evidence-Based Medicine Study Group. The patients' backgrounds; perioperative data; annual postoperative renal function; and prognostic surveys, performed over a median follow-up period of 10 years were obtained. RESULTS: In 930 surgical cases at the 14 registered hospitals, the 10-year recurrence-free survival rates of cT1a, cT1b, cT2, and cT3 were 0.9326, 0.8501, 0.5786, and 0.5101, respectively. Meanwhile, the 10-year overall survival rates were 0.9612, 0.8662, 0.7505, and 0.7209, respectively. Long-term observation in patients with cT1 showed that vessel involvement and high tumor grade were prognostic factors for recurrence. As a noteworthy fact, radical nephrectomy was performed in 53.3% of patients with cT1a at the regional hospitals. However, even in patients with preoperative chronic kidney disease stage 3, radical nephrectomy was not a prognostic factor of renal function. This indicates that compensatory mechanisms had been working for a long time in many patients who underwent radical nephrectomies without hypertension and preoperative proteinuria, which were predictors of end-stage renal disease. CONCLUSION: Based on a prospective long-term survey of the pre-robotic era, our results suggested no difference of the survival outcomes between the university hospital and regional hospitals. Our study provides baseline data to evaluate the outcomes of renal cancer robotic surgery, performed at regional hospitals.

[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.

Early Experiences of Contact Laser Vaporization of the Prostate using the 980 nm High Power Diode Laser for Benign Prostatic Hyperplasia.

OBJECTIVES: We report early experiences of contact laser vaporization of the prostate for symptomatic benign prostatic hyperplasia (BPH). METHODS: A total of 80 patients recruited at four institutions in Japan from April 2013 through September 2014 underwent contact laser vaporization of the prostate using 980 nm high power diode laser with an end-firing fiber in the contact mode. Patients were followed prospectively at 1 day, 2, 4, 8, 12, and 24 weeks, postoperatively per protocol, and at 1 and 2 years post-protocol. RESULTS: Of 76 eligible patients, 64 (84.2%) achieved more than 50% decrease in International Prostate Symptom Score at 24 weeks (95% confidence interval: 74.0-91.6%), clearing the pre-fixed non-inferiority efficacy level to transurethral resection of the prostate (65%). Symptom scores, maximum flow rate, post-void residual urine, and prostate volume showed significant improvements at 12 and 24 weeks after the surgery. Perioperative complications included transient urinary retention (n = 20), retrograde ejaculation (5), bladder neck contracture (4), urethral stricture (3), stone in prostatic bed (3), bladder stone (2), bladder perforation (1), bladder deformity (1), and transient urgency incontinence (1). Urinary retention and bladder neck contracture occurred almost exclusively at one institution. Improved symptom scores, maximum flow rate, and post-void residual urine observed at 24 weeks remained virtually unchanged at 1 and 2 years. CONCLUSIONS: Early experience of contact laser vaporization in Japan showed efficacy comparable to transurethral resection of the prostate as a surgical procedure for BPH at 24 weeks. Long-term efficacy of the procedure remains uncertain.

[Long-term prognosis of incidental renal cell carcinoma--clinical analysis of renal cell carcinoma detected by our health checkup].

PURPOSE: We retrospectively evaluated the characteristics and long-term prognosis of incidentally detected renal cell carcinoma by health checkup. MATERIALS AND METHODS: From January 1987 to December 2005, 556 patients were treated for renal cell carcinoma in our department. Among them, 56 patients were detected by abdominal ultrasonography in health checkup of our health care center. We reevaluated the pathological stage according to 2002 TNM classification and tumor type of renal cell carcinoma according to 2004 World Health Organization histological classification. Survival analysis was determined by Kaplan-Meier's method and log-rank test. RESULTS: Of the patients, 50 were male and 6 were female. The age of the patients ranged 37 to 68 years old at diagnosis (median 54 years). The tumors were located in the right kidney in 22 patients and in the left kidney in 34. Pathologically T1a tumors were found in 40 patients (71%), T1b in 13 (23%), T2 in 2 (4%) and T3b in 1 patients (2%). One case of T3b had N2 and M1 disease. The followup time after the operation ranged 3 to 215 months (median 121 months). Seven patients died of renal cell carcinoma. One of the 7 patients in T1a disease died at 64 months, 4 in T1b at 47, 91, 119, 163 months, 1 in T2 at 39 months and 1 in T3b at 13 months, postoperatively. The cause specific 10-year survival rate was 97% for T1a disease and 57% for T1b (p < 0.01), respectively. CONCLUSION: Most of renal cell carcinomas were T1a disease, which were detected incidentally by health checkup. The cause specific survival rate was significantly higher for T1a disease than for T1b. Our data suggested that early detection was important for good prognosis. The abdominal ultrasonography was only method for detection in routine health checkup and should be broadly implemented.

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.

Analysis of Thermally Denatured Depth in Laser Vaporization for Benign Prostatic Hyperplasia using a Simulation of Light Propagation and Heat Transfer (secondary publication).

Background and Aims: Laser vaporization of the prostate is expected as a less invasive treatment for benign prostatic hyperplasia (BPH), via the photothermal effect. In order to develop safer and more effective laser vaporization of the prostate, it is essential to set optimal irradiation parameters based on quantitative evaluation of temperature distribution and thermally denatured depth in prostate tissue. Method: A simulation model was therefore devised with light propagation and heat transfer calculation, and the vaporized and thermally denatured depths were estimated by the simulation model. Results: The results of the simulation were compared with those of an ex vivo experiment and clinical trial. Based on the accumulated data, the vaporized depth strongly depended on the distance between the optical fiber and the prostate tissue, and it was suggested that contact laser irradiation could vaporize the prostate tissue most effectively. Additionally, it was suggested by analyzing thermally denatured depth comprehensively that laser irradiation at the distance of 3 mm between the optical fiber and the prostate tissue was useful for hemostasis. Conclusions: This study enabled quantitative and reproducible analysis of laser vaporization for BPH and will play a role in clarification of the safety and efficacy of this treatment.

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.

Identification of two novel mutations in adenine phosphoribosyltransferase gene in patients with 2,8-dihydroxyadenine urolithiasis.

Five mutations in the adenine phosphoribosyltransferase (APRT) gene have been described in Japanese patients with APRT deficiency. We investigated the APRT gene from three patients with APRT deficiency and two novel mutations, G133D and V84M, were determined.

[The perioperative charge equivalence of radical prostatectomy with 1-year follow up since the diagnosis of prostate cancer].

We assessed the 1-year charges in the group of patients undergoing radical prostatectomy and the changes in hospital costs and resource use following implementation of a clinical care path. A total of 69 consecutive men treated with radical prostatectomy for clinically localized prostate cancer were enrolled in the study. Hospital and outpatient records were analyzed for each patient in regard to preoperative, operative and postoperative charges of a 12-month period. Parameters included number of encounters, diagnostic and therapeutic interventions, hospitalization and operative charges, and follow-up visits, diagnostic tests and interventions for 1 year. The mean first-year cost of treatment with radical prostatectomy for localized prostate cancer was 144 x 10(4) yen. The increases in the first-year cost with higher prostate specific antigen (PSA) level for the diagnosis level appeared to primarily be associated with increased inpatient resource use and greater use of hormonal therapy. Length of the stay in a hospital significantly influenced the first-year cost. After implementation of the radical prostatectomy care path hospital costs decreased by 30% (66 x 10(4) yen vs 46 x 10(4) yen), total costs decreased 40% (190 x 10(4) yen vs 113 x 10(4) yen) and length of hospital stay decreased by 56% (37.0 vs 16.6). The first-year costs with radical prostatectomy are influenced greatly by the hormonal therapy and the number of hospital days. By standardizing preoperative and postoperative management for patients undergoing radical prostatectomy, significant savings can be achieved toward shorter hospital stays and lower hospital costs.

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.

Surgical and oncologic outcomes of laparoscopic partial nephrectomy: a Japanese multi-institutional study of 1375 patients.

BACKGROUND AND PURPOSE: Despite clear trends toward minimally invasive surgery, information about laparoscopic partial nephrectomy (LPN) in Japan is sparse. We conducted a retrospective survey to clarify time trends for LPN and analyze surgical and oncologic outcomes. PATIENTS AND METHODS: A nationwide survey was performed. Between 1998 and 2008, 1375 patients underwent LPN at 54 institutions. Complications, patterns of tumor recurrence, and recurrence-free survival were analyzed. RESULTS: Renal pedicle clamping was used in 1031 (75%) cases, and renal cooling was performed in 64%. Median warm/cold ischemic time was 37/53 minutes. Median tumor size was 2.26 cm (interquartile range 1.6 to 2.7). Multivariate analysis identified total operative time, operative blood loss, and surgical margin status as independently associated with high grade (grade 3-5) urologic and nonurologic complications. Despite increases in central tumor, a trend was seen toward shorter warm/cold ischemic time in recent cases, and the overall complication rate did not change throughout the study period. With a median follow-up of 26 months for 1193 malignancies, recurrence occurred in 22 (1.7%) patients, including local recurrence in 7 (0.5%), lung in 8 (0.7%), lymph nodes in 2 (0.1%), and bone in 4 (0.3%). Of the 26 cases with positive surgical margins, local tumor recurrence occurred in only one. CONCLUSIONS: This is the first nationwide survey of LPN in Japan to be reported. LPN could be performed with acceptable positive margins and complication rates. Most tumor recurrences occur as metastases, and surgical margin status appears to have little impact on oncologic outcomes.

Morphological subtyping of papillary renal cell carcinoma: clinicopathological characteristics and prognosis.

AIM: The aim of the study was to evaluate the clinicopathological and prognostic significance of morphological subtyping of papillary renal cell carcinoma (PRCC). METHODS: The patients treated for renal cell carcinoma in our department from January 1985 to March 2006 were evaluated retrospectively. Thirty-two of the 591 patients (5.4%) were diagnosed with PRCC. To determine the prognostic factors, we re-evaluated the pathological stage according to the 2002 TNM classification of malignant tumors, and the tumor type of renal cell carcinoma according to the 2004 World Health Organization histological classification. Survival was analysed using the Kaplan-Meier method and the log-rank test. RESULTS: The age at diagnosis ranged from 33 to 81 years (median: 63 years old) and the follow-up time after the surgical treatment ranged from 4 to 191 months (median: 54 months). The cancer-specific 5-year survival rate of the 32 PRCC patients was 74%. Pathologically, 17 patients (53%) and 15 patients (47%) were diagnosed with type 1 and type 2 PRCC, respectively. The type 2 PRCC patients had a significantly higher tumor grade (P < 0.001), a more advanced stage (P < 0.001), more frequent vascular invasion (P < 0.001), and a higher sarcomatoid component (P = 0.038) compared to the type 1 PRCC patients. The type 1 patients had a better cancer-specific 5-year survival rate than the type 2 patients (94% vs 50%) (P = 0.008). CONCLUSION: The morphological subtyping of PRCC is significantly associated with clinicopathological features and the prognosis. Our results provide evidence of the clinical utility of dividing PRCC into two subtypes.

Impact of salvage therapy for biochemical recurrence on health-related quality of life following radical prostatectomy.

OBJECTIVE: To determine the impact of salvage therapy for prostate-specific antigen (PSA) recurrence on the health-related quality of life (HRQOL) of patients after radical retropubic prostatectomy (RP). METHODS: Between January 2000 and December 2003, a total of 249 patients who underwent RP were available for 2-year follow up. Of the respondents, 203 men did not show evidence of recurrence (group A), and 46 men received salvage hormonal therapy and/or radiotherapy after RP because of a rise in PSA (group B). The general and prostate-target HRQOL was assessed with the Medical Outcomes Study 36-Item Short Form and University of California, Los Angeles Prostate Cancer Index, respectively. Patients completed the HRQOL instruments by mail at baseline and at 24 months after RP. RESULTS: All of the patients completed both questionnaires. At baseline no significant differences were found between the two groups in any of the HRQOL domains. There were significant improvements in mental health and social function for the patients without biochemical recurrence postoperatively. Repeated measure anova revealed significantly different patterns of alteration in several general HRQOL domains among the treatment groups. The urinary and bowel domains were equivalent between the two treatment groups at baseline and 24 months after RP. The patients treated with salvage hormonal therapy tended to show delayed recovery of sexual function. CONCLUSION: Using a self-administered questionnaire, biochemical recurrence following RP was found to impose a substantial burden in patients with localized prostate cancer.

Psychological distress in Japanese men with localized prostate cancer.

OBJECTIVE: To investigate: (i) the level of psychological distress; and (ii) the relationships between the level of psychological distress and general or disease-specific HRQOL of Japanese men with localized prostate cancer following surgery or radiotherapy. PATIENTS AND METHODS: The study was a retrospective cross-sectional survey of 253 men with localized prostate cancer treated with radical prostatectomy and 87 with external beam radiotherapy were collected. The measures used four questionnaires including: (i) the Medical Outcomes Study 36-Item Health Survey; (ii) The University of California, Los Angeles Prostate Cancer Index; (iii) International Prostate Symptom Score; and (iv) Hospital Anxiety and Depression Scale (HADS). RESULTS: Mean anxiety and depression scores were 4.0 and 4.7, respectively (standard deviation, 3.3 and 3.7). On the anxiety section of HADS, 291 patients (85%) scored 7 points or less; and on the depression scale, 183 (54%) patients scored 4 points or less. Those 'cases' (HADS total, >10) with psychological distress scored lower in all domains of the general and disease related health-related quality of life (HRQOL) than the 'non-cases' (HADS total,

Natural history of voiding function after radical retropubic prostatectomy.

OBJECTIVES: To report results from a 2-year longitudinal survey of lower urinary tract function and quality of life (QOL) in men after radical retropubic prostatectomy (RP) for localized prostate cancer. METHODS: Between November 2001 and September 2003, self-report assessments were provided to 225 patients who underwent RP alone. The University of California Los Angeles Prostate Cancer Index (UCLA PCI), the International Prostate Symptom Score (IPSS), and the IPSS QOL score were administered before and 3, 6, 12, 18, and 24 months after RP. RESULTS: The overall mean total IPSS and IPSS QOL score progressively improved with time. The mean scores of several components improved significantly postoperatively. No significant difference was observed in nocturia between the baseline assessment and any of the postoperative follow-up assessments. The IPSS of the younger patients continued to recover significantly more rapidly than that of the older patients after RP. According to the UCLA PCI scores, urinary function substantially declined just after RP and continued to recover but scored lower than the baseline. The mean total IPSS and IPSS QOL scores observed in men with a UCLA PCI urinary function score of 80 or more were significantly better than in men with scores less than 80 at 24 months postoperatively. CONCLUSIONS: Radical retropubic prostatectomy has a significant beneficial effect on lower urinary tract symptoms. The rate of improvement was lowest for nocturia among the seven symptoms of IPSS. Urinary continence after RP and age can affect the recovery of voiding function.
