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.

Impact of nocturia on disease-specific quality of life for men with localized prostate cancer.

OBJECTIVES: We assessed the impact of nocturia on the general and disease-specific health-related quality of life (HRQOL) for men with localized prostate cancer. MATERIALS AND METHODS: A total of 620 men with prostate cancer were enrolled to our study. All of the subjects completed the questionnaires before primary treatment. We evaluated general HRQOL with the Short Form 36-Item Health Survey (SF-36). The prostate-specific HRQOL was assessed with the University of California, Los Angeles Prostate Cancer Index (PCI). Night-time urinary frequency was assessed by the seventh score of the International Prostate Symptom Score. RESULTS: Of the 581 men, 47 (8%) men reported no nocturia, while 189 (32%) were categorized with one void per night and 345 (59%) with two or more voids per night. Disease-specific HRQOL, including urinary function, bowel function, and sexual function, was negatively associated with increase in frequency of nocturia. The subjects who reported two or more voids per night had significantly lower scores than those of the no nocturia or one void per night group in several domains of the SF-36 and PCI. Based on the proportion odds model, age, urinary function, bowel function, and sexual function showed a strong association with frequency of nocturia. CONCLUSIONS: We found a strong association between the frequency of nocturia and disease-specific HRQOL as well as general HRQOL. Increased severity of nocturia is negatively correlated with overall health status and HRQOL outcomes.

Long-term quality of life following primary treatment in men with clinical stage T3 prostate cancer.

OBJECTIVES: We evaluated the changes of health-related quality of life (HRQOL) during the 5 years after radical prostatectomy (RP) or external beam radiation therapy (EBRT) for clinical stage T3 prostate cancer (cT3PC). PATIENTS AND METHODS: A total of 750 patients who underwent RP (n = 575) or EBRT (n = 175) participated in our longitudinal outcomes study. Of these patients, 48 RP patients (8%) and 63 EBRT patients (36%) presented with cT3PC and were included in this analysis. Patients completed the general and disease-specific HRQOL with the Short Form 36 (SF-36) and University of California, Los Angeles Prostate Cancer Index, respectively. RESULTS: When examining the mean SF-36 values by time, there was significant impact on treatment outcomes for several items of the general HRQOL in the RP subjects. Those who underwent EBRT reported no significant changes in the general HRQOL throughout the follow-up period. With regard to disease-specific HRQOL, the RP subjects had significantly worse urinary HRQOL post-operatively than the EBRT subjects (P < 0.001). The scores for sexual function declined over the 60 months, but more so in the RP group. The two groups showed similar bowel HRQOL scores throughout the follow-up periods. CONCLUSIONS: Both primary treatments for cT3PC can offer satisfactory functional outcomes from the HRQOL perspective, except for a persistent decrease in the sexual activity score. These results may guide the treatment selection and clinical management of patients with HRQOL impairments after treatment for cT3PC.

Five-year follow-up of health-related quality of life after intensity-modulated radiation therapy for prostate cancer.

OBJECTIVE: We evaluated health-related quality of life (HRQOL) in patients with localized prostate cancer who underwent intensity-modulated radiation therapy (IMRT) or three-field conformal radiotherapy (3DCRT). METHODS: A total of 97 patients underwent 3DCRT and 36 underwent IMRT for localized prostate cancer between 2002 and 2004. We measured the general and disease-specific HRQOL with the Medical Outcomes Study 36-Item Health Survey and University of California, Los Angeles Prostate Cancer Index, respectively. RESULTS: There were no significant differences in the pre-operative characteristics of the two groups. The patients in the 3DCRT group were more likely to receive hormonal therapy compared with the IMRT group before and after radiation therapy (P < 0.001 and P = 0.011, respectively). With regard to general HRQOL domains, both the 3DCRT and IMRT group scores showed no significant difference between baseline and any of the observation periods. At 60 months after treatment, the 3DCRT group had significantly worse bowel function and bother scores than baseline (both P < 0.001). On the other hand, there were no significant differences between the baseline and any of the post-treatment time periods in the IMRT group. In the 3DCRT group, sexual function remained substantially lower than the baseline level (P = 0.023). The IMRT group tended to show a decrease in sexual function, which was not statistically significant (P = 0.11). CONCLUSIONS: IMRT can provide the possibility to deliver a high irradiation dose to the prostate with satisfactory functional outcomes for long-term periods.

Metastatic renal cell carcinoma to right ventricle without vena caval involvement.

Cardiac metastases from renal cell carcinoma without vena caval involvement are extremely rare. We report 49-year-old man who presented symptoms of heart failure and thrombocytopenia. Computed tomography and echocardiography revealed a left renal tumor and a right ventricular mass without vena caval involvement. His symptoms progressed rapidly and he died at nine days following diagnosis of the right ventricular tumor.

[Quality of life following endocrine therapy for advanced prostate cancer: a comparative study between LH-RH agonist 1-month depot and 3-month depot].

PURPOSE: There were few studies which reported the longitudinal quality of life (QOL) for Japanese men who received endocrine therapy for advanced or metastatic prostate cancer. A pilot randomized trial was conducted to assess QOL and the incidence of hot flash following endocrine therapy using luteinizing hormone-releasing hormone (LH-RH) agonist goserelin acetate 1-month or 3-month depot alone in patients with advanced or metastatic prostate cancer. MATERIAL AND METHODS: A total of 28 patients with advanced or metastatic prostate cancer who received LH-RH analogue goserelin acetate depot alone for 12 months were randomized (1:1) to two different formulations. Fifteen patients received the 1-month depot and thirteen patients received 3-month depot, namely Zoladex 3.6 mg depot and Zoladex LA 10.8 mg depot, respectively. We measured health related QOL using European Organization for Research and Treatment of Cancer (EORTC) and EuroQol (EQ-5D) questionnaire and evaluated the incidence of hot flashes between the two groups for one year after diagnosis. Moreover, we evaluated the incidence of hot flashes between the 1M and 3M depot. A baseline interview was conducted before treatment. Follow-up interviews were conducted in person at scheduled study visits of 3, 6, 9 and 12 months after treatment. RESULTS: Five (18%) patients dropped out of the study. Thus, we analyzed 23 eligible patients (11 in the 1M arms and 12 in the 3M arms). No significant differences between the two treatment arms were detected in categories of age, average pre- PSA values, Gleason scores and clinical T stage. According to EORTC, each treatment group showed similar QOL scores in all domains before and after treatment. With regard to EQ-5D, the 1M-treatnent arm reported better utility scores than 3M treatment arm, which was no significant statistically. The overall incidence of hot flash was 61% (58% in 1M group and 64% in 3M group). CONCLUSION: There were no differences with regard to general and disease specific HRQOL between the both formulations of goserelin acetate. Hot flashes are the major adverse effects of endocrine therapy for Japanese patients with prostate cancer.

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.

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,

Health-related quality of life after intensity modulated radiation therapy for localized prostate cancer: comparison with conventional and conformal radiotherapy.

OBJECTIVE: No previous studies have reported the longitudinal health-related quality of life (HRQOL) for intensity modulated radiation therapy (IMRT). We compared HRQOL after IMRT with that after conventional and after conformal radiation therapy (XRT). METHODS: A total of 110 patients underwent XRT (34 patients underwent conventional radiation therapy and 76 underwent conformal radiation therapy) and 30 underwent IMRT for clinically localized prostate cancer between 2000 and 2002. We measured the general and disease-specific HRQOL using the Medical Outcomes Study 36-Item Health Survey and University of California, Los Angeles, Prostate Cancer Index, respectively. RESULTS: There were no significant differences in the preoperative characteristics and HRQOL scores of the two groups. Repeated measure analyses of variance revealed significantly different patterns of alteration in several general HRQOL domains between XRT and the IMRT groups. In the urinary domain, there was no difference in the alteration patterns between the two groups. The XRT group suffered worse bowel function at 3 and 6 months than the IMRT group (P < 0.05). In the XRT group, sexual function decreased at 3 months and remained substantially lower than the baseline level. However, the IMRT group showed no significant difference from the baseline level at any of the observation periods. At 18 months the XRT group showed worse sexual function than the IMRT group. CONCLUSION: The two approaches showed different longitudinal profiles regarding general and disease-specific HRQOL during the first 2 years after treatment. The IMRT approach produced little impairment in bowel and sexual function.

Health related quality of life in Japanese men after radical prostatectomy or radiation therapy for localized prostate cancer.

BACKGROUND: We performed a retrospective survey of general and disease specific health-related quality of life (HRQOL) after radical prostatectomy (RP) and external beam radiotherapy (XRT) in Japanese men. METHODS: A total of 186 patients underwent RP and 78 underwent XRT for clinically localized prostate cancer between 2000 and 2002. We measured the general and disease specific HRQOL with the MOS 36-Item Health Survey and the University of California, Los Angeles Prostate Cancer Index, respectively. Each treatment group was further divided into four subgroups according to the time scale. RESULTS: Patients from the RP group were significantly younger than those from the XRT group. The tumor characteristics differed significantly in their distributions among the treatment groups. Patients undergoing XRT had low scores in most of the general measures of HRQOL just after treatment, but after 6 months there were no differences between the treatment groups, except for the physical domains. The RP group was associated with worse urinary function, whereas the XRT group had worse bowel function and bother during the first 6 months after treatment. Thereafter, however, urinary and bowel domain did not differ between the groups. Both groups reported poor sexual function, although the RP group scored lower sexual bother. CONCLUSION: The patients who underwent RP had significantly worse urinary and better bowel function than those treated with XRT. Both treatment groups had decrements in sexual function throughout the post-treatment period; careful attention should be paid to this side-effect in preoperative counselling, especially in younger patients, regardless of the primary treatments.
