- Abstract
Purpose: We investigated induction carboplatin based chemotherapy in patients with nonorgan confined urothelial carcinoma who were considered unfit for cisplatin. A comparison was made with patients who received induction cisplatin based combination chemotherapy., Materials and Methods: We identified 167 patients with nonorgan confined urothelial carcinoma who received induction cisplatin based combination chemotherapy (126) or gemcitabine and carboplatin (41) at our hospital between 1990 and 2010. Of the patients 124 completed 4 cycles of cisplatin based combination chemotherapy or gemcitabine and carboplatin. Clinical response (ycTNM) was evaluated according to RECIST (Response Evaluation Criteria in Solid Tumors) 1.1. Radical cystectomy and bilateral extended pelvic lymph node dissection were performed in 106 patients. A pathological complete response was defined as no evidence of disease (ypT0N0). Disease specific survival was analyzed using the Kaplan-Meier method. Multivariate analysis was performed., Results: Complete clinical response rates did not differ significantly among the treatment groups. A pathological complete response was seen in 33.7% of specimens in the cisplatin based combination chemotherapy group vs 30.3% in the gemcitabine and carboplatin group (p = 0.808). We found no significant difference in disease specific survival between patients who started cisplatin based combination chemotherapy and those who started gemcitabine and carboplatin. For patients who completed 4 cycles and underwent radical cystectomy there was also no significant difference in disease specific survival between the groups. On multivariate analysis a pathological complete response was the only variable significantly associated with disease specific survival (p<0.045)., Conclusions: Induction gemcitabine and carboplatin for nonorgan confined urothelial carcinoma achieves clinical and pathological response rates, and survival outcomes comparable to those of the cisplatin based combination chemotherapy schemes. Our data suggest that a carboplatin based regimen can be considered a reasonable alternative for cisplatin unfit patients in the preoperative setting., (Copyright © 2013. Published by Elsevier Inc.)

- Abstract
Objective: To evaluate the efficacy and tolerability of bicalutamide 150 mg once-daily as immediate hormonal therapy in patients with prostate cancer or as adjuvant to radical prostatectomy or radiotherapy., Patients and Methods: In all, 8113 patients with localized (T1-2, N0/Nx) or locally advanced (T3-4, any N; or any T, N+) prostate cancer (all M0) were enrolled in three complementary, double-blind, placebo-controlled trials. Patients were randomized to receive standard care plus either oral bicalutamide 150 mg once-daily or oral placebo. Primary endpoints were progression-free survival (PFS) and overall survival (OS). Data were collated from individual trials and evaluated in a combined analysis., Results: Overall, at a median follow-up of 9.7 years, bicalutamide significantly improved PFS (hazard ratio 0.85, 95% confidence interval 0.79-0.91; P= 0.001). Compared with placebo there was no difference in OS (hazard ratio 1.01, P= 0.77). Patients who derived benefit from bicalutamide in terms of PFS were those with locally advanced disease, with OS significantly favouring bicalutamide in patients with locally advanced disease undergoing radiotherapy (P= 0.031). Patients with localized disease showed no clinically or statistically significant improvements in PFS; there was a survival trend in favour of placebo in patients with localized disease undergoing watchful waiting (P= 0.054). The overall tolerability of bicalutamide was consistent with previous analyses, with breast pain (73.7%) and gynaecomastia (68.8%) the most frequently reported adverse events in patients randomized to bicalutamide., Conclusions: Bicalutamide 150 mg, either as monotherapy or adjuvant to standard care, improved PFS in patients with locally advanced prostate cancer, but not in patients with localized disease. A pre-planned subset analysis showed a benefit for OS in patients with locally advanced disease undergoing radiotherapy. Bicalutamide 150 mg might represent an alternative for patients with locally advanced prostate cancer considering androgen-deprivation therapy., ([PETER IVERSEN], [MANFRED P.

- Abstract
Background and Purpose: The ongoing Early Prostate Cancer (EPC) programme is assessing bicalutamide ('Casodex') 150 mg, either alone or as adjuvant to treatment of curative intent, in patients with localised or locally advanced prostate cancer (n=8113). This paper presents an exploratory analysis of the subgroup of the EPC programme who received radiotherapy with curative intent (n=1370) in order to determine the efficacy (in terms of progression-free survival [PFS]) and tolerability of bicalutamide 150 mg in this setting., Patients and Methods: 1370 patients with T1-4, MO, any N prostate cancer received bicalutamide 150 mg or placebo adjuvant to radiotherapy of curative intent. This analysis was undertaken at median 5.3 years' follow-up., Results: In patients with locally advanced disease (n=305), bicalutamide adjuvant to radiotherapy significantly increased PFS by 53% (event-time ratio 1.53; 95% confidence intervals [CI] 1.16, 2.02) compared with placebo and reduced the risk of disease progression by 42% (hazard ration [HR] 0.58; 95% CI 0.41, 0.84; P=0.00348). In these patients, objective progression was experienced by 33.5% of those randomised to bicalutamide versus 48.6% for those randomised to placebo. The between-group difference in patients with localised disease (n=1065) failed to reach statistical significance (HR 0.80; 95% CI 0.62, 1.03; P=0.088). The most common adverse events were breast pain (74.8%) and gynaecomastia (66.6%), which were mild to moderate in >90% of cases., Conclusions: Bicalutamide 150 mg/day given as adjuvant to radiotherapy significantly improved PFS in patients with locally advanced prostate cancer. For patients with localised disease, the results at this stage from the radiotherapy subgroup and the overall EPC programme suggest that adjuvant hormonal therapy is currently not appropriate. There were no unexpected tolerability findings.

- Abstract
Purpose: We evaluated the efficacy and tolerability of 150 mg bicalutamide daily given in addition to standard care, in patients with localized or locally advanced prostate cancer., Materials and Methods: The bicalutamide Early Prostate Cancer program consists of 3 randomized, double blind, placebo controlled trials prospectively designed for combined analysis. A total of 8,113 men with T1b-T4, M0, any N (N0 in 1 trial) prostate cancer were randomized to bicalutamide 150 mg/day (4,052) or placebo (4,061) in addition to standard care (radical prostatectomy, radiotherapy or watchful waiting). Primary end points were objective progression-free survival (PFS) and overall survival., Results: At median 5.4 years of followup (21.6% progression events) bicalutamide significantly improved PFS in the overall population. This result was driven by positive results in trials 24 and 25, with the North American trial (trial 23) showing no difference. Patients with locally advanced disease gained most benefit from bicalutamide in terms of PFS, irrespective of underlying therapy. Overall survival was similar in the bicalutamide and placebo groups, across the program and in each trial. Among watchful waiting patients survival appeared to be improved with bicalutamide in those with locally advanced disease, whereas survival appeared to be reduced with bicalutamide in those with localized disease. The most common adverse events with bicalutamide were gynecomastia and breast pain. Other adverse events occurred with a similarly low incidence in the 2 treatment groups., Conclusions: This analysis confirms that bicalutamide provides benefit in patients with locally advanced disease. The current data suggest that early or adjuvant hormonal therapy for patients at low risk of disease progression, such as those with localized disease, is not appropriate.

- Abstract
Objectives: To report an exploratory subgroup analysis assessing the extent to which the overall benefit found in the Early Prostate Cancer program is dependent on lymph node status at randomization. The program is ongoing, and the overall survival data are immature. The first combined analysis of the bicalutamide (Casodex) Early Prostate Cancer program at 3 years' median follow-up showed that bicalutamide, 150 mg once daily, plus standard care (radical prostatectomy, radiotherapy, or watchful waiting), significantly reduced the risk of objective progression and prostate-specific antigen (PSA) doubling in patients with localized/locally advanced prostate cancer., Methods: Men (n = 8113) with localized/locally advanced disease received bicalutamide 150 mg or placebo once daily, plus standard care. The time to event data (objective progression, PSA doubling) was analyzed by lymph node status at randomization., Results: Compared with standard care alone, bicalutamide significantly reduced the risk of objective progression, irrespective of lymph node status, with the most pronounced reduction in patients with N+ (hazard ratio [HR] 0.29; 95% confidence interval [CI] 0.15 to 0.56) compared with those with N0 (HR 0.59; 95% CI 0.48 to 0.73) and Nx (HR 0.60; 95% CI 0.50 to 0.72) disease. The largest decrease in risk of PSA doubling with bicalutamide was observed in N+ disease (HR 0.16; 95% CI 0.09 to 0.29), with significantly reduced risks seen in N0 (HR 0.45; 95% CI 0.40 to 0.51) and Nx (HR 0.38; 95% CI 0.33 to 0.44) disease., Conclusions: The greatest reduction in the risk of objective progression and PSA doubling with bicalutamide was seen in patients with N+ disease. However, bicalutamide also provided a statistically significant benefit in those with N0 and Nx disease.

- Abstract
Purpose: We determine the efficacy and tolerability of bicalutamide as immediate therapy, either alone or as adjuvant to treatment of curative intent, in patients with clinically localized or locally advanced prostate cancer., Materials and Methods: This international program consists of 3 ongoing, randomized, double-blind, placebo controlled clinical trials (trials 23, 24, and 25). Men with localized or locally advanced (T1-T4, Nx/N0, M0) prostate cancer were randomized to receive 150 mg. bicalutamide daily or placebo, in addition to standard care with radical prostatectomy, radiotherapy or watchful waiting. Primary end points are time to objective progression and overall survival. In this first analysis data from the trials were combined in a single overview analysis according to protocol., Results: Data are available for 8,113 patients (4,052 randomized to bicalutamide, 4,061 to standard care alone) at a median followup of 3.0 years. Treatment with bicalutamide provided a highly significant reduction of 42% in the risk of objective progression compared with standard care alone (9.0% versus 13.8%, hazards ratio 0.58; 95% confidence interval 0.51, 0.66; p <<0.0001). The overall result was reflected in 2 of the 3 trials (trials 24 and 25) with trial 3 (trial 23) showing a nonsignificant difference at this time. Reductions in the risk of disease progression were seen across the entire patient population, irrespective of primary treatment or disease stage. Overall survival data are currently immature and longer followup will determine if there is also a survival benefit with bicalutamide. The most frequently reported side effects of bicalutamide were gynecomastia and breast pain., Conclusions: Immediate treatment with 150 mg. bicalutamide daily, either alone or as adjuvant to treatment of curative intent, significantly reduces the risk of disease progression in patients with localized or locally advanced prostate cancer. This benefit must be balanced with the morbidity associated with long-term hormonal therapy. Followup is ongoing to determine potential survival benefits of this treatment approach.

- Abstract
Objectives: To evaluate the feasibility, efficacy, and toxicity of antegrade chemotherapy delivered continuously as adjuvant treatment for patients with upper tract transitional cell carcinoma., Methods: During a 6-year interval, 12 patients with upper tract transitional cell malignancies underwent continuous antegrade intraluminal infusion chemotherapy (CAIIC) with adriamycin. After placement of percutaneous access and surgical treatment of the primary lesion, patients received 5-day cycles of CAIIC. Patients received between two and four treatment cycles at 2-week intervals. After therapy, patients with no evidence of residual disease were then monitored long-term with retrograde pyelography and upper tract cytology., Results: Twelve patients underwent a total of 35 5-day cycles of CAIIC. No patient experienced hematologic and/or local/regional toxicity during or after drug infusion. Three patients were treated for upper tract carcinoma in situ, and 9 patients had discrete exophytic tumors. Two patients died (treatment unrelated) before a final assessment of therapeutic outcome, leaving 10 patients available for evaluation of the therapeutic response. One patient with carcinoma in situ and 5 of 7 patients with discrete upper tract tumors remained disease free after surgery and adjuvant therapy. Both patients with discrete tumors in whom therapy failed had residual gross disease after primary surgical treatment., Conclusions: CAIIC using adriamycin was well tolerated for periods of up to 5 days over multiple cycles. Early data suggest a limited efficacy in treating patients with gross residual disease. The efficacy of this approach in preventing the recurrence of upper tract disease after surgical ablation awaits further assessment.

- Abstract
The management of hormone-refractory metastatic prostate cancer remains a therapeutic dilemma. We report the results of a phase II trial with deferoxamine administrated at a dose of 50 mg/kg (maximum dose 5 g) administered intravenously over 8 hr daily, repeated for 5 days at 4-week intervals for 2 courses. Fourteen patients with advanced hormone-refractory prostate cancer were treated and 28 courses were delivered. Essentially no toxicity was observed. Using combined clinical and prostate-specific antigen (PSA) criteria. 13 of 14 patients had disease progression. However, 9 of 14 patients had stable measurable or evaluable disease and progressed solely based on PSA criteria. Deferoxamine in this dose and schedule has no activity in hormone-refractory prostate cancer. Further investigation of the effect of deferoxamine on PSA production/expression is warranted.

- Abstract
Background: 5-fluorouracil (5-FU) is a known radiosensitizer that enhances efficacy, in vivo and in vitro, when administered during radiotherapy. The following study was performed to evaluate the toxicity of continuous infusion 5-FU administered concomitant with brachytherapy in patients with locally advanced prostate cancer., Methods: Over a 26-month period, a total of 25 patients with newly diagnosed, locally advanced prostate cancer underwent radioactive gold (Au198) brachytherapy. Twenty-four of 25 patients were surgically staged and confirmed node negative. Au198 seed placement was performed transperineally under fluoroscopic and ultrasonographic guidance using an average of 195 mCi of Au198. Within 4 hours after seed placement, 25 patients received 5-FU administered as a continuous infusion over 4 days, at 1 of 8 dose levels ranging from 200-1100 mg/m2/day. Patients had clinical follow-up for a minimum of 1 year. Decreases in serum prostate specific antigen (PSA) and prostate volume (normalized to pretreatment values) were determined at 12 months., Results: 5-FU associated toxicity was negligible, with Grade 1 nausea in four patients and no Grade 2 or higher toxicity. No unique locoregional toxicity was noted. At 12 months after treatment, PSA values decreased on average to 16.4% of pretreatment values. Twelve-month prostate volumes decreased to 55% of the pretreatment values., Conclusions: These findings suggest that continuous infusion 5-FU can be administered safely concomitant with brachytherapy at doses up to 1100 mg/m2 per day for 4 days.
