RESUMEN

BACKGROUND: Lower urinary tract symptoms due to benign prostate enlargement (LUTS/BPE) can lead to significant disturbances to health-related quality of life (HRQoL) and psychological well-being. The aim of this study was to evaluate the effect of pharmacological treatment of LUTS/BPE on disease specific and generic QOL measures. METHODS: Evolution was a European prospective, multicenter multi-national, observational registry collecting real-life clinical data over 2 years on the management of LUTS/BPE in primary and secondary care. This study investigated disease-specific QOL using questionnaires such as IPSS Q8, BPH Impact Index (BII) and generic QOL using questionnaires like EuroQOL Five Dimension (EQ5D) which encompassed EQ5D VAS and EQ5D health index. RESULTS: The registry enrolled 1838 BPE patients and 1246 patients were evaluable at the end of 24 months. Nearly 70% of patients in the study were previously treated with medical therapy and 17% of these had already discontinued medical treatment previously for various reasons with lack of efficacy being the most common. The mean time since diagnosis of LUTS in the previously treated group was 4.7 years (0-26 years). Medical management produced statistically significant improvement in QOL (disease specific and generic) in previously untreated patients and an insignificant change in generic QOL in previously treated patients. CONCLUSIONS: After 5-years from the onset of symptoms, LUTS/BPE patients previously treated with medication had significantly impaired QOL in patients in a manner comparable to other chronic diseases. Earlier intervention with minimally invasive surgical techniques (MIT) should be considered in LUTS/BPE patients that do not show a significant improvement in QOL with medical therapy.

RESUMEN

BACKGROUND: To use the European Association of Urology Research Foundation (EAURF) registry data to determine the proportion of contemporary Lower Urinary Tract Symptoms associated with Benign Prostatic Enlargement (LUTS/BPE) patients prescribed phytotherapy, and to determine their subjective quality of life and clinical progression responses. METHODS: This was a prospective multicenter multinational observational registry study, conducted over 2 years. Men ≥ 50 years seeking LUTS/BPE were divided at baseline into two cohorts, presently/recently untreated patients (PUP) commencing pharmacotherapy at baseline and presently/recently treated patients (c-PTP) continuing previously received pharmacotherapy, with 24-month follow-up (FU). RESULTS: Overall, 2175 patients were enrolled with 1838 analyzed. Of the PUP cohort (n = 575), 92 (16%) received phytotherapy and 65 (71%, n = 65/92) completed 24-month FU, with France prescribing 34% (n = 30/89) the highest proportion of phytotherapy among all LUTS/BPE medications. In the c-PTP group (n = 1263), only 69 (5%) patients were using phytotherapy, falling to n = 35/69 (51%) at 24-month FU (highest in France 20% (n = 43/210)). Though defined disease progression occurred in ≤ 20%, with only 1% proceeding to surgical intervention, in both groups, clinically meaningful improvement was lower and symptom persistence was higher in PUP but similar in the treated (c-PTP) patients on phytotherapy compared to the other LUTS/BPE medication. CONCLUSION: Low heterogeneous prescribing rates for phytotherapy were reported in both PUP and c-PTP cohorts over the 24-month FU. Although phytotherapy led to subjective improvements, healthcare practitioners should prescribe them with caution until higher quality evidence and guideline recommendations supporting its use are available.

RESUMEN

PURPOSE: A cost minimisation analysis compares the costs of different interventions' to ascertain the least expensive over time. We compared different prostate targeted drug treatments with TURP to identify the optimal cost saving duration of a medical therapy for symptomatic benign prostatic enlargement (BPE). METHODS: The Evolution registry is a prospective, multicentre registry, conducted by the European Association of Urology Research Foundation (EAUrf) for 24 months in 5 European countries. Evolution was designed to register the management of symptomatic BPE in clinical practice settings in 5 European countries. Direct cost evaluation associated with prostate targeted medical therapies and TURP was also recorded and analysed. RESULTS: In total, 1838 men were enrolled with 1246 evaluable at 24 months. Medical therapies were more cost saving than TURP for treatment durations ranging from 2.9 to 70.4 years. Cost saving depended on both medication class and individual country assessed. Daily tamsulosin monotherapy was more cost saving than TURP for ≤ 13.9 years in Germany compared to ≤ 32.7 years in Italy. Daily finasteride monotherapy was more cost saving for ≤ 5.9 years in France compared to ≤ 36.9 years in Spain. Combination therapy was more cost saving for ≤ 5.9 years for Italian patients versus ≤ 13.8 years in Germany. CONCLUSIONS: BPE medical management was more cost saving than TURP for different specific treatment durations. Information from this study will allow clinicians to convey medical and surgical costs over time, to both patients and payors alike, when considering BPE treatment.

RESUMEN

We compared intravesical instillations with mitomycin-C (MMC), Bacillus Calmette-Guerin (BCG) Tice, and BCG-RIVM in patients with pTa-pT1 papillary carcinoma and primary carcinoma in situ (CIS) of the bladder. Nine instillations with MMC were given or 6 weekly instillations with BCG. Early recurrences were treated with additional instillations. For toxicity and efficacy 437 patients were evaluated with a median follow-up of 32 months (range 12-56). Drug-induced and bacterial cystitis were the most frequent side-effects. The number and severity of side-effects (chi 2 test) were comparable in both BCG groups, but were significantly less in the MMC group for drug-induced cystitis (P = 0.009), other local side-effects (P = 0.004) and systemic side-effects (P < 0.001). The disease-free percentage (log-rank test) showed no significant difference for the three arms for papillary tumours (P = 0.08), nor the CIS (P = 0.20), although for CIS numbers are small. Additional instillations did not influence toxicity or efficacy.

RESUMEN

OBJECTIVES: To evaluate the short- and long-term effects of neoadjuvant hormonal treatment in locally confined prostate cancer. METHODS: We report the preliminary results of 354 patients (199 with a clinical T2 tumor and 155 with a clinical T3 tumor) of whom 164 randomly received neoadjuvant total androgen deprivation using a luteinizing-hormone-releasing hormone (LHRH) analog (goserelin) plus flutamide for a period of 3 months. RESULTS: Serum prostate-specific antigen (PSA) levels and prostatic volume decreased from a mean of 19.9 ng/mL and 37.7 cm3 to a mean of 0.8 ng/mL and 26.5 cm3 after 3 months of neoadjuvant therapy. "Clinical down-staging" was seen in 32% in the neoadjuvantly treated group. "Pathological downstaging" percentages were 6% and 16% in the direct radical prostatectomy group and neoadjuvantly-treated group, respectively (P < 0.01). In patients with clinical T2 tumors, a significant difference in number of positive margins was shown in favor of the neoadjuvantly treated group (P < 0.01). In patients with clinical T3 tumors, a significant difference could not be detected (P = 0.14). In 215 patients with a mean follow-up time of 15 months, the calculated 95% confidence intervals of mean time of PSA progression-free survival were 26 to 35 months in the neoadjuvantly-treated group and 28 to 37 months in the direct radical prostatectomy group, indicating no significant differences between treatment groups. However, follow-up time is currently too short to draw definite conclusions. CONCLUSIONS: These early data confirm high understaging percentages in clinical staging. The clinical relevance of the statistically significant smaller numbers of patients with positive margins in the neoadjuvantly treated group with a clinical T2 tumor will have to be confirmed when further follow-up allows an accurate evaluation of time to PSA progression, local recurrence, and distant metastases. Presently, neoadjuvant therapy is not advisable outside clinical research settings.

RESUMEN

OBJECTIVES: To investigate if the circadian rhythm of urinary flow values varies within groups of patients with varying degrees of bladder outlet obstruction. METHODS: A total of 170 patients with lower urinary tract symptoms suggestive of bladder outlet obstruction used a home-based uroflowmeter and produced a total of 1670 correctly measured flows at home. These patients also underwent a screening program with free urinary flowmetry in the hospital and a urodynamic pressure and flow study. RESULTS: There is a circadian variability in urinary flow values in men with higher grades of obstruction. These men have a higher peak urinary flow with a smaller voided volume and thus a shorter flow time in the early afternoon when compared with late evening, early morning, and the midnight to morning periods. CONCLUSIONS: This significantly greater maximum flow in the afternoon in men with higher grades of obstruction can be an important bias in studies where the primary end point is to assess a small improvement in maximum flow. Therefore, the circadian rhythm of uroflow has to be taken into account in the evaluation of the efficacy of treatment. Patients participating in clinical research studies should produce their urinary flow in the clinic always during the same time period, either in the morning or in the afternoon, and should not switch their appointment time.

RESUMEN

OBJECTIVES: To compare the pharmacodynamics and tolerability of the new goserelin acetate 10.8-mg depot with the 3.6-mg depot in patients with advanced prostate cancer during the first 3 months of therapy. METHODS: One hundred sixty patients were randomized in two comparative studies to receive either the 10.8-mg goserelin acetate depot every 12 weeks or the 3.6-mg goserelin acetate depot every 4 weeks for 12 weeks and then the 10.8-mg depot every 12 weeks thereafter. Data for pharmacodynamic assessments were collected prospectively, whereas clinical response data were collected retrospectively. RESULTS: Serum testosterone profiles of the 10.8-mg goserelin acetate depot and the 3.6-mg goserelin acetate depot were similar; testosterone levels in both groups fell below castrate levels by day 21 after administration. Decreases in serum prostate-specific antigen level after 3 months of therapy were also similar in both groups: 94% with the 10.8-mg depot and 92.5% with the 3.6-mg depot. For all patients, the median time to progression was 152.7 weeks and the median time to death was 213.6 weeks. The safety profile of the 10.8-mg goserelin acetate depot was similar to that of the 3.6-mg depot; hot flashes was the most common adverse event. The incidence of injection site reactions was very low (2 [0.3%] of 614 administrations). CONCLUSIONS: The new 10.8-mg depot was pharmacodynamically equivalent to the current 3.6-mg depot and was well tolerated, both locally and systemically. The observed times to progression and survival were as expected in this patient population. The 10.8-mg goserelin-acetate depot provided a dosing schedule that was convenient for the patient and the physician, and it has the potential to reduce health care costs while maintaining the quality of life in patients being treated for advanced prostate cancer.

RESUMEN

OBJECTIVES: In this article we describe the long-term follow-up of patients with carcinoma in situ (CIS) of the urinary bladder and examine whether the extent of CIS, the presence of associated papillary tumors, or the response to treatment influence the course of the disease. METHODS: Fifty-two patients with CIS of the bladder, treated in a randomized prospective study, are described. In 23 patients with concomitant papillary tumors all macroscopically visible lesions were completely resected transurethrally (TUR). CIS was histologically confirmed in all patients by biopsy, 29 of whom had primary CIS. The patients were treated with intravesical mitomycin, bacille Calmette-Guérin (BCG)-RIVM or BCG-Tice and followed regularly by urine cytology, cystoscopy, and biopsy. RESULTS: Complete response was achieved in 65% of the patients. Of these responders, 24% later had a recurrence of CIS or a superficial tumor and 18% had progressive disease (PD). In the nonresponding patients, progression occurred in 67%. In the whole group, PD was seen in 35% of the patients, and radical cystectomy was performed in 21%. The disease-related death rate was 13%. The risk for recurrence or PD was not higher in patients with more extensive CIS, defined as three or more positive biopsy results or when CIS was associated with papillary tumors compared to patients with one or two biopsy specimens positive for CIS or CIS alone. Nonresponding patients showed a significantly higher progression rate and cystectomy rate than responding patients (P = 0.0012 and 0.008, respectively). CONCLUSIONS: CIS of the bladder is a malignancy with a poor prognosis, especially in patients not responding after intravesical treatment. Early detection and adjuvant intravesical treatment after TUR of concomitant papillary tumors are required. In patients not responding after intravesical treatment, radical surgery is necessary before progression occurs. The number of biopsies positive for CIS, not the presence of concomitant superficial tumors, was an indicator for progression or recurrence.

RESUMEN

OBJECTIVES: We investigated the symptomatic and urodynamic effects of several noninvasive and minimally invasive treatment modalities to quantify these effects and to compare subjective and objective results within groups with various degrees of obstruction. METHODS: In a prospective study at one center, 487 patients who completed a full screening program including urodynamic investigation started treatment with watchful waiting, terazosin, transurethral microwave thermotherapy, or laser treatment of the prostate; they were re-evaluated symptomatically and urodynamically after 6 months of therapy. The symptomatic and urodynamic results of 87 patients from another center who underwent transurethral resection of the prostate and who had their second urodynamic evaluation 6 months after surgery were also included. RESULTS: In patients without bladder outlet obstruction (BOO), improvement in maximum flow and symptom scores with little change in the degree of obstruction was most apparent, whereas a decrease of detrusor pressure at maximum flow was observed mainly in patients with BOO. The urodynamic effect but not the symptomatic effect of treatments depended on the initial grade of BOO. Urodynamic changes were more marked in the minimally invasive treatment groups compared with the noninvasive treatment groups. CONCLUSIONS: In symptomatic patients with benign prostatic hyperplasia, symptomatic improvement in the short term does not seem to depend on changes in urodynamic parameters. Future well-controlled studies focusing on the durability of symptomatic and urodynamic effects will be needed to illustrate the relative potential of urodynamic and other clinical parameters to predict a favorable response to current and innovative treatments.

RESUMEN

OBJECTIVES: To evaluate clinical and urodynamic changes in patients with and without bladder outlet obstruction (BOO) and to compare the clinical and urodynamic results of terazosin treatment between patients with and without BOO. METHODS: In a prospective study, 97 patients who completed a full screening program including urodynamic investigation with pressure-flow study analysis started treatment with terazosin. A total of 60 patients completed 6 months of treatment and were re-evaluated with International Prostate Symptom Scores (IPSS), uroflowmetry, and urodynamic investigation with pressure-flow study analysis. Patients were stratified using the linear passive urethral resistance relation (lin-PURR) classification according to Schäfer. Patients with a lin-PURR of 3 or more were classified as patients with BOO and patients with a lin-PURR of 2 or less were classified as patients without BOO. The clinical and urodynamic changes within and between the groups with and without BOO were evaluated. RESULTS: Terazosin resulted in significant symptomatic relief (9 points on the IPSS scale; P < 0.01) and a significant improvement of free urinary flow (3.0 mL/s; P < 0.01). In patients with BOO, a statistically significant improvement of all urodynamic obstruction variables (P < 0.01) was shown. In patients without BOO, a significant improvement of free urinary flow (4.4 mL/s; P < 0.01), a statistically significantly improved bladder capacity (increase of 70 mL; P = 0.01), and no statistically significant changes in urodynamic obstruction variables (P > 0.05) were shown. Patients with a hypoactive detrusor were more prone to early dropout. When comparing the changes of symptoms (P = 0.89), quality of life (P = 0.85), and the number of patients with improvements of free uroflow of at least 30% (P = 0.15), there appeared to be no significant difference between the groups with and without BOO. CONCLUSIONS: Although there is a statistically significant difference in urodynamic response to terazosin treatment between patients with and without BOO, we cannot recommend the use of pressure-flow studies in the selection of patients for terazosin treatment because the clinical results of treatment appear not to be significantly different between patients with and without BOO. It seems more useful, and certainly less expensive and less invasive, to start alpha 1-blocker therapy if, on clinical grounds, the urologist considers the patient to be a candidate for alpha 1-blocker therapy, and to continue therapy in those who respond.

RESUMEN

OBJECTIVES: To determine long-term efficacy of intravesical mitomycin C (MMC) versus bacille Calmette-Guérin (BCG) in patients with superficial bladder cancer with regard to recurrences and progression. METHODS: Patients with superficial bladder cancer (pTa, pT1, pTis) were treated with intravesical MMC (30 mg, weekly for 4 weeks, and thereafter monthly for 5 months) or BCG (weekly for 6 weeks). RESULTS: Three hundred forty-four patients were eligible (171 in the BCG group, 173 in the MMC group). The median follow-up was 7.2 years. Toxicity was not significantly different between the two treatment groups. Efficacy of the two treatment policies was similar with regard to tumor recurrence. With regard to progression to invasive disease, MMC was more effective than BCG in patients without carcinoma in situ (CIS) (P = 0.006). CONCLUSIONS: We can confirm the conclusions of other studies that intravesical treatment with 30 mg of MMC remains an effective treatment option that can also be used in high-risk patients. Like others, we could not confirm that a 6-week course of BCG is more effective in the prevention of tumor progression. Of the 33 patients with tumor progression after intravesical therapy, 20 died of bladder cancer, confirming that tumor progression after intravesical therapy carries a poor prognosis. In this study the difference in toxicity between BCG and MMC was not significant. When comparing studies with MMC and BCG, differences in treatment schedule and/or patient selection should be kept in mind.

RESUMEN

The incidence and methods available for the diagnosis of metastatic prostate cancer, together with the development and efficacy of various treatments, are discussed. In patients with good prognostic characteristics, maximal androgen deprivation, with blockade of both testicular and adrenal androgens, seems to be the favored approach. Surgical castration, although effective, seems inferior to depot luteinizing hormone-releasing hormone therapy with respect to patients' acceptance and preference. Nonsteroidal antiandrogens, such as flutamide, have advantages over steroidal compounds both in efficacy and side effects. Recent studies have demonstrated that combination therapy may be superior in terms of progression-free survival and overall survival in patients with metastatic prostate cancer.

RESUMEN

BACKGROUND AND PURPOSE: Neoadjuvant hormonal therapy (NHT) has been used for more than a decade for prostate cancer, but the results of clinical trials are only now becoming available, and the value of the treatment is not yet clear. The authors reviewed the results of the European randomized trials to increase our understanding of the role of this treatment. PATIENTS AND METHODS: We report the results of 402 patients with prostate cancer (220 clinical stage T(2) and 182 clinical T(3) tumor), of whom 192 were randomly assigned to NHT using an LHRH analog (goserelin) plus flutamide for a period of 3 months (NHT) and 210 underwent radical prostatectomy only (RP). RESULTS: "Pathologic downstaging" occurred in 15% and 7% of the NHT and the RP group, respectively (P < 0.01). Fifty of the 189 patients in the NHT group (26%) and 68 of the 209 patients in the RP group (33%) developed disease progression, as determined by rising serum prostate specific antigen (PSA) concentration. Regarding local disease progression, the advantage for the use of NHT approached but did not reach statistical significance:18 of 189 patients (10%) in the NHT group and 33 of 209 patients (16%) in the RP group (P = 0. 07). CONCLUSIONS: Although there was a trend in favor of the NHT group with respect to the number of patients with PSA progression and the number with local disease progression, it did not reach statistical significance. These results may be attributable to a true lack of benefit of adjuvant hormonal ablation or to a lack of statistical power to demonstrate a difference in a subset of patients who might benefit from this therapy.

RESUMEN

Since 1941, when the androgen dependency of prostatic carcinoma was described first, the question whether neoadjuvant hormone manipulation enhances surgical curability has been of actual importance. With the availability of reversible luteinizing hormone-releasing hormone analogues and non-steroidal antiandrogens, interest in preoperative hormonal manipulation has recently been reinnovated. An overview of the published, sometimes conflicting clinical and pathological studies evaluating the value of neoadjuvant hormone manipulation is given. We conclude that further well-controlled clinical investigations comparing downstaging and downgrading percentages, percentages of local control and survival are needed to prove the benefit of neoadjuvant treatment in patients with locally confined prostatic carcinoma.

RESUMEN

OBJECTIVE: To compare the efficacy and tolerability of the alpha 1 A-subtype selective drug tamsulosin with the nonsubtype-selective agent alfuzosin in the treatment of patients with lower urinary tract symptoms (LUTS) suggestive of bladder outlet obstruction (BOO), often termed symptomatic benign prostatic hyperplasia (BPH). PATIENTS AND METHODS: The study comprised 256 patients with benign prostatic enlargement and LUTS suggestive of BOO (symptomatic BPH) who received tamsulosin 0.4 mg once daily or alfuzosin 2.5 mg three times daily during 12 weeks of treatment. The response was assessed by measurements of maximum urinary flow rate (Qmax), a symptom score (Boyarsky) and blood pressure at regular intervals. RESULTS: Tamsulosin and alfuzosin produced comparable improvements in Qmax and total Boyarsky symptom score. Both treatments were well tolerated with respect to adverse events. Tamsulosin had no statistically significant effect on blood pressure compared with baseline but alfuzosin induced a significant reduction in both standing and supine blood pressure, compared with baseline (P < 0.05). CONCLUSION: Tamsulosin is the first adrenoceptor antagonist that is selective for the alpha 1 A-subtype; this specificity may explain its lack of effect on blood pressure compared with alfuzosin, an agent that is not receptor subtype specific. Moreover, this finding may partly explain why tamsulosin, in contrast to other currently available alpha 1-adrenoceptor antagonists, can be administered without dose titration. Another advantage compared with alfuzosin (and prazosin) is the once-daily dosing regimen of tamsulosin.

RESUMEN

OBJECTIVE: To evaluate the long-term efficacy and safety of terazosin in the treatment of benign prostatic hyperplasia (BPH). METHODS: Thirty-three sites in 13 countries enrolled men with BPH who had an International Prostate Symptom Score (IPSS) > or = 12 [corrected]. After a 2-week, no-treatment lead-in period and a 26-week, single-blind treatment period, patients responding to terazosin were randomly assigned to receive either terazosin or placebo for a 24-week, double-blind withdrawal period. RESULTS: Of the initial 427 patients enrolled, 378 were evaluable, 273 of whom completed the single-blind period, of which 186 patients were randomized. During the single-blind treatment period, IPSS, quality-of-life score (QOL), peak flow rate (PFR), and nocturia score (NOC) improved significantly (p < or = 0.05). During the double-blind withdrawal period, IPSS, QOL, PFR, and NOC deteriorated significantly in the placebo group compared with the terazosin group. The most common adverse event resulting in premature termination from the study was dizziness. There were no clinically important mean reductions in diastolic blood pressure (DBP) for patients normotensive at baseline. Terazosin significantly reduced mean DBP in hypertensive patients during the single-blind period and maintained the reduction during the double-blind period. CONCLUSION: Treatment with terazosin has a beneficial effect on BPH, continuing for at least 12 months, and can be safely considered for medium- to long-term use in those who benefit.

RESUMEN

Prophylactic intravesical treatment with chemotherapeutic agents or one of the different strains of the immunomodulator bacillus Calmette-Guérin (BCG) reduces tumor recurrence and may prevent progression after transurethral resection (TUR) of superficial bladder cancer. Clinical and pathological prognostic factors are used to categorize different groups at risk for disease recurrence and progression. Solitary low-grade (G1, 2A), low-stage (pTa) tumors have less than a 5% risk of progression, while pT1 G3 tumors with concomitant carcinoma in situ (CIS) have a considerably higher risk of progression and metastases. Thus, prospective clinical trials should consider the different risks associated with different prognostic groups and stratify patients accordingly. The Dutch Cooperative Trial evaluated mitomycin versus BCG-Tice versus BCG-RIVM in 469 patients with pTA/pT1 carcinoma and CIS of the urinary bladder after TUR. Of 437 evaluable patients, 50 had CIS, 254 had pTA tumors, and 133 had pT1 tumors. No statistical differences were observed in toxicity between the two strains of BCG, but local and systemic side effects were more frequent in the BCG groups versus the mitomycin group. No differences in response rate were observed between the 3 treatment groups in patients with CIS. A statistically significant difference in favor of mitomycin was seen, however, in patients with papillary tumors. Mitomycin and BCG-RIVM were equally effective, and mitomycin proved significantly more effective than BCG-Tice. No significant difference in efficacy was observed between the two strains of BCG. Disease recurrence during the study in patients with papillary tumors was seen in 43% of mitomycin-treated patients, 64% of the BCG-Tice group, and 46% of patients treated with BCG-Rivm. However, a subgroup analysis for time to first recurrence for pTa versus pT1 and for grade 1 and 2 versus grade 3 papillary tumors showed no statistically significant between-group difference. Further studies comparing identical regimens, doses, and patient groups are needed to define more clearly which patient groups and tumors are more likely to respond to intravesical therapy.

RESUMEN

OBJECTIVES: To evaluate the long-term effects of 3-month neoadjuvant hormonal treatment in patients treated by radical prostatectomy for locally confined prostate cancer. METHODS: We report the results of 402 patients (220 with a clinical T2 tumor and 182 with a clinical T3 tumor) of whom 192 randomly received neoadjuvant total androgen deprivation using a LHRH analogue (goserelin) plus flutamide for a period of 3 months and 210 underwent radical prostatectomy only. RESULTS: 'Clinical downstaging' was seen in 30% of cases in the neoadjuvantly treated group (NEO). 'Pathological downstaging' occurred in 7 and 15% of cases in the direct radical prostatectomy (DP) group and the NEO group, respectively (p<0.01). In patients with clinical T2 as well as in patients with clinical T3 tumors, a significant difference in the number of positive margins was shown in favor of the NEO group (cT2, p<0.01; cT3, p = 0.01). This advantage, although there was a trend in favor of the NEO group, specifically in cT2 tumors, did not translate in a significantly better PSA progression rate (p = 0.18). However, when evaluating the local control rate in cT2 tumors, we observed local recurrence in 3 of 102 (3%) patients in the NEO group versus 12 of 114 (11%) patients in the DP group. The difference is statistically significant (p = 0.03). In the cT3 group, this difference was not statistically significant (NEO group: 15 of 87 (17%), and DP group: 21 of 95 (22%) patients; p = 0.41). CONCLUSIONS: In this study, the clinical revelance of pathological downstaging and the lower percentage of patients with positive margins in the neoadjuvantly treated group with a clinical T2 tumor is not confirmed by a lower PSA progression rate. However, this study indicates that there may be a trend that this advantage in favor of the NEO group directly translates into a better local control rate in clinical T2 tumors. Better local control in cT2 tumors is only going to be of relevance if subsequently you can show that there is a better survival for these patients. Unfortunately, this article reports a study which is not yet mature enough to show relevant information. Presently, neoadjuvant therapy should not be given outside clinical research settings.
