Technique of da Vinci robot-assisted anatomic radical prostatectomy.

OBJECTIVES: Robotic radical prostatectomy is a new procedure for treating prostate cancer. Many centers are attempting this new modality but a detailed description of the technique has not yet been published. We report the technique as performed at the Vattikuti Urology Institute. METHODS: At Vattikuti Urology Institute, we have performed more than 30 such operations and have standardized the technique for safe and reproducible treatment of prostate cancer. We collected the patient data and surgical logs to improve and standardize this procedure. We recorded the operation and made relevant modifications after reviewing the recordings to improve the outcome. RESULTS: The operation was developed on the scientific foundations of anatomic radical prostatectomy as described by Walsh and the laparoscopic prostatectomy developed at Montsouris. Our technique differs from these procedures because of the need for two surgical teams and the use of fine, endo-wrist instruments with three-dimensional stereoscopic visualization. We describe the patient setup, positioning, port placement, preparation of the robot, docking of the arms, and the surgical steps of performing anatomic prostatectomy with robotic assistance. CONCLUSIONS: This report describes the current technique of robotic prostatectomy as developed at the Vattikuti Urology Institute.

Laparoscopic radical prostatectomy. preliminary pathologic evaluation.

OBJECTIVES: Although there is increasing evidence of the interest in the laparoscopic approach for radical prostatectomy, carcinologic data, including surgical margin status, remain to be described. METHODS: We analyzed the oncologic results of laparoscopic prostatectomies performed during 2000. The data were compared with retropubic prostatectomies performed between 1994 and 1997 by the same two senior urologists. After matching for preoperative prostate-specific antigen level, the final analysis included 139 patients in both groups, with similar data for age, biopsy Gleason score, and number of positive biopsies. All specimens were processed with the same method of pathologic evaluation. The results were compared using either the chi-square test or Student t test. RESULTS: The mean prostate weight and rate of positive lymph nodes were similar in both groups. No statistical difference was observed in the distribution of either the radical prostatectomy Gleason score or the pathologic stage between the laparoscopic and retropubic groups. In contrast, the decrease in the rate of positive surgical margins was statistically significant in the laparoscopic approach compared with the retropubic approach (P <0.02), particularly in localized cancers (pT2). No difference was observed in either the length or the distribution of the margin location. The rate of positive apical margins in organ-confined disease was significantly decreased in the laparoscopic group. CONCLUSIONS: These results suggest that laparoscopic prostatectomy performed by trained surgeons does not lead to an increased risk of positive margins compared with the retropubic approach.

Open prostatectomy for benign prostatic enlargement in southern Europe in the late 1990s: a contemporary series of 1800 interventions.

OBJECTIVES: Contemporary series of open prostatectomies from Western countries are rare. Frequently, the analysis of the outcome of open prostatectomy refers to old experiences or to series from developing countries. Any comparison with transurethral resection of the prostate can be invalidated by complications of open surgery because of the lack of an adequate healthcare system and technology. METHODS: The Sicilian-Calabrian Society of Urology performed a retrospective study to assess the surgical management of benign prostatic hyperplasia in Sicily and Calabria in 1997 and 1998. A three-page questionnaire was sent to the 36 urologic units of these two Italian regions with more than 7.5 million inhabitants. RESULTS: Twenty-six units (72.3%) replied. Of 31,558 patients treated for symptomatic benign prostatic hyperplasia, 5636 underwent surgery. Open prostatectomy (n = 1804) accounted for 32% of all surgical treatment. The median prostate volume was 75 cm(3) and the median serum prostate-specific antigen level was 3.7 ng/mL. The postoperative median hospitalization time was 7 days. Concomitant low urinary tract disease was present in 25% of the patients. Severe bleeding occurred in 11.6% of open prostatectomies. Blood transfusions were given in 8.2% of cases. Sepsis was reported in 8.6% of the patients. Reinterventions, within 2 years, mainly due to bladder neck stenosis, were reported in 3.6% of cases. CONCLUSIONS: The results of the present survey provide a current picture of open prostatectomy. This procedure, even if performed nowadays and in Western countries, shows the same significant rate of early and late complications reported in the past or in less-developed countries.

Biochemical recurrence without PSA progression characterizes a subset of patients after radical prostatectomy. Prostate-specific antigen.

OBJECTIVES: To characterize a subset of patients with biochemical recurrence after radical prostatectomy but with little, if any, subsequent rise in serum prostate-specific antigen (PSA) and no clinical progression during long-term follow-up. METHODS: Of a series of 600 patients, 158 with biochemical recurrence after radical prostatectomy were examined. We identified a subset with measurable serum PSA levels during long-term follow-up, but with very low PSA velocity and no clinical recurrence. Serum PSA was measured with the ultrasensitive TOSOH assay with a PSA recurrence defined as a serum PSA of 0.07 ng/mL or greater. RESULTS: We identified 14 patients (8.8% of biochemical recurrences) with a detectable serum PSA level after radical prostatectomy yet without clinical or PSA progression at a mean follow-up after radical prostatectomy of 10.3 years. The mean time to PSA recurrence was 5.8 years, and the mean PSA velocity after recurrence was 0.028 ng/mL/yr. No clinical or pathologic features were found that could be used to identify this subset of patients. CONCLUSIONS: A subset of patients with biochemical recurrence after radical prostatectomy will not exhibit a progressive rise in serum PSA or clinical progression at 10 years follow-up. This suggests that serum PSA kinetics should be observed after biochemical recurrence before adjuvant hormonal therapy or radiotherapy.

Radical perineal prostatectomy in obese patients.

OBJECTIVES: To evaluate the efficacy of radical perineal prostatectomy in obese patients. No study has ever been published providing evidence of success of any type of prostatectomy specifically in patients with significant truncal obesity. METHODS: A retrospective review of 103 patients who underwent radical perineal prostatectomy between 1996 and 2002 was performed. Obesity is defined as having a body mass index greater than 30 kg/m(2). Seven obese patients were found. The operative time, blood loss, hospital length of stay, perioperative complications, urinary continence, and quality of specimen were assessed. RESULTS: The mean age was 61 years (range 56 to 67). The body mass index ranged between 30.21 and 47.9 (average 39.27). The average operative time and blood loss was 142 minutes and 542 mL, respectively. No complications occurred and no blood transfusions were needed perioperatively. Two specimens had a positive surgical margin. Six (85.7%) of the 7 patients went home on postoperative day 2; the remaining patient left on day 3. The 1-year continence rate was 66%. CONCLUSIONS: Radical perineal prostatectomy remains an excellent option for obese patients. It remains to be seen if this is the case with radical retropubic prostatectomy.

Early hospital discharge after radical retropubic prostatectomy: impact on cost and complication rate.

OBJECTIVES: To assess the impact of shortened hospital stay after radical retropubic prostatectomy for localized prostate cancer on complication rates and hospital costs. METHODS: A comparison of results between 171 consecutive patients undergoing radical retropubic prostatectomy between July 1989 and January 1993 (group 1) and 101 consecutive patients operated on since February 1993 (group 2) during a prospective effort to reduce hospital length of stay by home-based preoperative bowel preparation, direct admission to the operating room on the day of surgery, earlier and more extensive postoperative ambulation, earlier initiation of postoperative oral intake, earlier use of oral analgesics, and routine pelvic drain removal at 72 to 96 hours after surgery independent of volume of drainage. RESULTS: Median length of stay was reduced from 8 to 5 days (p < 0.0001, group 1 versus group 2), with 10% of patients in group 2 having hospital stays of 4 days or less. The overall nature and rate of complications (13.5% versus 11.9%, p = NS) were similar in both groups. Reduced length of stay was associated with a 32% decrease in hospital-associated cost per case in group 2 versus group 1 for patients in diagnosis-related group (DRG) 334 (radical prostatectomy with comorbidity) and a 26% decrease for DRG 335 (radical prostatectomy without comorbidity). CONCLUSIONS: Reduced hospital length of stay after radical retropubic prostatectomy results in significant cost savings without increasing morbidity.

The anatomic radical perineal prostatectomy: a contemporary and anatomic approach.

OBJECTIVES: We applied the advances in anatomic techniques as developed for the radical retropubic prostatectomy to the perineal approach to radical prostatectomy. The anatomic radical perineal prostatectomy maximizes cancer control and minimizes postoperative incontinence and impotence. This technique capitalizes on the many advantages associated with the perineal approach to the prostate. METHODS: The anatomic radical perineal prostatectomy addresses the posterior surface and posterior bladder neck regions prior to urethral division at the prostatic apex. Anatomic dissection of the striated urethral sphincter and preservation of the bladder neck, as well as a "watertight" anastomosis, are accomplished with excellent exposure. Cavernosal nerve preservation is possible in appropriately selected patients. Data are accumulated prospectively and reported herein. RESULTS: Prostate-specific antigen detectability is seen in 2% and 4% of pT2 and pT2 to T3b cases, respectively at an average follow-up of 1 year. Immediate full continence is seen in 30% of cases; ultimately, 97.5% achieve full urinary control. Nerve-sparing techniques result in spontaneous erectile activity in 73%. Average length of hospital stay is less than 2 days, with most recent patients discharged on the day after surgery. CONCLUSIONS: The anatomic radical perineal prostatectomy is a safe and effective method of treating men with clinically localized prostate cancer and should be part of every urologist's surgical armamentarium.

PSA levels and the rate of positive surgical margins in radical prostatectomy specimens preceded by androgen blockade in clinical B2 (T2bNxMo) prostate cancer. The Lupron Depot Neoadjuvant Study Group.

OBJECTIVES: Neoadjuvant hormonal therapy reduces positive margins in patients undergoing radical prostatectomy. All patients experience a decrease in serum prostate specific antigen (PSA), but not always to a level that is nondetectable. The results of several prospective, randomized trials indicate that the incidence of positive margins decreases with the use of androgen deprivation prior to radical prostatectomy. It has been suggested that a greater decline in PSA levels would result in fewer positive margins. In a recent US trial of patients with T2bNxMO prostate cancer, we reported that 18% of patients randomized to receive 3 months of leuprolide acetate and flutamide had positive margins, compared to 48% of those who had radical prostatectomy alone (P < 0.001). We correlated the PSA levels prior to and following androgen deprivation and the presence of a positive margin following radical prostatectomy (RP). METHODS: One hundred and thirty-seven of 149 patients randomized to receive presurgery androgen deprivation (AD) underwent radical prostatectomy. Of these, 135 had a PSA level obtained both prior to androgen deprivation and prior to surgery. We analyzed the percent positive margins in patients whose PSA values became undetectable and in those whose values remained above 0.1 ng/mL despite androgen deprivation. RESULTS: Eight of 43 patients (19%) with a nadir PSA < or = 0.1 ng/mL had a positive surgical margin and 16/92 (17%) with a nadir PSA > 0.1 ng/mL had tumor at the margin. There were no statistical differences in these two groups (P = 1.0 by Fisher's Exact Test [two-tailed], and the Pearson correlation was -0.015). CONCLUSIONS: There was no correlation between an undetectable PSA and a PSA > 0.1 ng/mL and the presence of tumor at the margin when 3 months of AD was given prior to RP. It is possible that longer periods of AD prior to RP will reduce PSA to an undetectable level in a higher percent of patients. However, these data suggest that an undetectable level will not result in less positive margins.

Systematic sextant biopsies in the prediction of extracapsular extension at radical prostatectomy.

OBJECTIVES: To evaluate the clinical utility of transrectal ultrasound-guided systematic sextant needle biopsies in the prediction of extracapsular extension (ECE) at radical prostatectomy. METHODS: A retrospective analysis of 104 men who underwent systematic biopsy and radical prostatectomy at our institution was performed. All patients underwent preoperative staging by transrectal ultrasound and transrectal ultrasound-guided systematic sextant biopsy. The presence of pathologic ECE was correlated to the number of positive core biopsies on each side of the prostate by chi-square analysis. Sensitivity, specificity, positive and negative predictive values, and likelihood ratios (LRs) were calculated for both positive (two or three biopsies positive per side) and negative (no or one positive biopsy per side) test results. RESULTS: Forty-two (20.2%) of 208 sides demonstrated evidence of ECE at radical prostatectomy. Chi-square analysis demonstrated a significant correlation between the number of positive biopsies and the presence of ECE at radical prostatectomy (P = 0.001). Overall, the finding of multiple positive core biopsies (two or three per side) had predictive value with regard to the presence of ECE (sensitivity 62%, specificity 77%, positive predictive value 40%, negative predictive value 89%). The corresponding LRs were 2.5 for a positive and 0.5 for a negative test result. CONCLUSIONS: The probability of ECE at radical prostatectomy can be more accurately assessed preoperatively by the combined use of transrectal ultrasound and systematic sextant needle biopsies.

Immediate sexual rehabilitation by simultaneous placement of penile prosthesis in patients undergoing radical prostatectomy: initial results in 50 patients.

OBJECTIVES: To evaluate the results of simultaneous placement of a penile prosthesis with radical prostatectomy. METHODS: From June 1993 to June 1996, 50 men underwent a combination procedure of non-nerve sparing radical retropubic prostatectomy and placement of a penile prosthesis. We performed a retrospective chart review of these patients, examining patient age, preoperative prostate-specific antigen level, Gleason score, operative time, estimated blood loss, analgesic use, length of hospital stay, time until intercourse, and complications. This group was compared with a group of 72 men undergoing radical prostatectomy alone during the same time interval. RESULTS: No significant differences were noted in preoperative patient variables. The mean operative time for prosthesis insertion was 82 minutes, and the mean time to sexual intercourse was 12.7 weeks. No prosthesis infections have occurred, with a mean follow-up of 1.7 years. Four men (8%) have required revision of their inflatable penile prosthesis. There were no significant differences between the combination procedure and radical prostatectomy alone with regard to estimated blood loss, length of hospital stay, or analgesic use. CONCLUSIONS: Simultaneous placement of a penile prosthesis during radical prostatectomy provides early return to sexual function, with no apparent increase in morbidity. Further study will be required to determine the impact of combination surgery on psychosocial adjustment and quality of life.

Ambulatory radical retropubic prostatectomy.

OBJECTIVES: To review the experience of 40 consecutive patients who underwent radical retropubic prostatectomy and to determine if and how the procedure could be performed safely on an ambulatory basis. METHODS: Between June 20, 1994 and November 26, 1996, 40 consecutive men with clinically localized prostate carcinoma underwent radical retropubic prostatectomy. Retrospective data regarding the patient population, patient satisfaction, clinical outcome, and length of hospitalization were evaluated. RESULTS: The average age for the patients was 62.6 years (range 44 to 75) with an average PSA of 10.44 ng/mL. Eighty percent (32 of 40) of the patients were discharged on postoperative day 1, 17.5% (7 of 40) were discharged on postoperative day 2, and 2.5% (1 of 40) were discharged on postoperative day 7. The average operative time was 89.5 minutes (range 65 to 135), measured from the time of incision to completion of closure. The organ-confined rate was 80% (32 of 40). The continence evaluated at 6 months was 90.9% (30 of 33). The potency at 4 months was 35% (10 of 28) and at 1 year was 55.6% (10 of 18). Postoperative complications were minimal, with 7.5% (3 of 40) bladder neck contractures and 2.5% (1 of 40) wound infections. Patient satisfaction assessed by questionnaires revealed that 90% (36 of 40) thought that the length of hospitalization was adequate and 97.5% (39 of 40) would choose to have the procedure again. A second series of 15 patients have also undergone radical retropubic prostatectomy utilizing a pelvic block to expedite discharge. Of these 15 procedures, 10 were performed on an ambulatory basis. CONCLUSIONS: Radical retropubic prostatectomy can be performed expediently with the maintenance of patient satisfaction, continence rates, potency rates, recurrence rates, complication rates, and pathologic results. The advantage to such an approach is expedited patient discharge, cost savings to the medical system, and no alteration in patient recovery or clinical outcome, such as organ-confined rate, potency, and continence. In this series, the majority of patients were discharged on postoperative day 1. On the basis of this experience, we have performed the procedure on an outpatient basis, while maintaining the same high quality of care. To date, 10 patients have undergone ambulatory radical retropubic prostatectomy and were discharged the same day of surgery without complications.

Comparative quality-of-life analysis after radical prostatectomy or external beam radiation for localized prostate cancer.

OBJECTIVES: To determine and compare quality-of-life (QOL) evaluations from patients who received external beam radiation therapy or radical prostatectomy for the treatment of localized prostate cancer, and to compare differences in QOL assessments for urinary and sexual function after radical prostatectomy as reported by patient and physician. METHODS: Two hundred three patients treated by radical prostatectomy and 257 patients treated by external beam irradiation, all beyond 12-month follow-up after therapy, responded to a QOL questionnaire. The difference in responses with regard to bladder, bowel, and sexual function, overall satisfaction with treatment, and choice of the same treatment were assessed. Satisfaction with and choice of the same treatment were also specifically assessed according to bowel and bladder function and current disease status. The medical records of patients treated by radical prostatectomy were reviewed by an independent data manager to record the physician's assessment of continence and sexual function for comparison with that patient's assessment as noted in the questionnaire. RESULTS: Problems with urinary continence were more frequent among patients treated by radical prostatectomy; problems with gastrointestinal function were more frequent after irradiation. Sexual dysfunction was similar in both groups, although surgical patients experienced a greater impact on sexual relationships. The physician estimates of urinary continence were more favorable than the patient-reported outcomes. However, the physician estimate of sexual function closely approximated that of the patient. Preservation of sexual function among patients who underwent nerve-sparing surgery was disappointingly low. Only for the response to the question dealing with difficulty in achieving an erection was there a statistically significant benefit for patients receiving nerve-sparing versus non-nerve-sparing procedures. Patient satisfaction with and choice of the same treatment varied according to function and current disease status. Patients who had incontinence or bowel dysfunction or had evidence of recurrent disease were statistically less likely to choose the same treatment again when compared with functional and disease-free counterparts. Because irradiated patients were on average 6 years older than surgical patients, responses were adjusted for age; adjustment for age did not alter results. CONCLUSIONS: QOL is determined by the treatment received, by the assessment source, and by the patient's function and disease status at the time of assessment. Prospective and longitudinal studies will more accurately quantify immediate and chronic alterations in QOL. Uniformity of evaluation through consolidation of QOL instruments will permit more accurate cross-series and cross-treatment comparisons.

Positive surgical margins with radical retropubic prostatectomy: anatomic site-specific pathologic analysis and impact on prognosis.

OBJECTIVES: To correlate the extent and location of positive surgical margins after radical prostatectomy with disease progression. METHODS: Data on 495 patients who underwent radical prostatectomy by one surgeon were analyzed. All radical prostatectomy specimens were sectioned entirely using 2 to 3-mm step sections by one pathologist. One hundred fifty-one patients (30.5%) had one or more positive surgical margins and were subjected to further detailed analysis. Recurrence was defined as a serum prostate-specific antigen (PSA) level of 0.2 ng/mL and rising on at least two postoperative measurements. RESULTS: The mean follow-up was 25.3 months (range 3 to 73). The overall recurrence rate was 13.3%. Neoadjuvant hormonal treatment was given to 37 (25%) of those with a positive margin. Patients with positive surgical margins had a significantly higher incidence of recurrence compared with those with negative margins (27.8% versus 6.9%, P = 0.001). The recurrence rate for various locations was 29% apex/urethra, 30% posterior, 33% anterior, 36% lateral, 48% posterolateral, and 57% bladder neck. Time to recurrence was shorter in patients older than 70 years (P<0.055); with a preoperative PSA greater than 10 ng/mL (P<0.0001); with a biopsy Gleason score greater than 7 (P = 0.02); with a prostatectomy Gleason score greater than 7 (P<0.001); with seminal vesicle invasion (P = 0.0001); having more than 1 location of a positive margin (P = 0.002); or having a positive margin at the bladder neck (P = 0.0003) or the posterolateral surface of the prostate (P = 0.02) compared with other locations. Multivariate proportional hazards analyses indicated that age older than 70 (P = 0.005), a prostatectomy Gleason score of 7 (P = 0.015) or 8 to 10 (P = 0.003), and positive margin(s) at the bladder neck (P = 0.003) were independently associated with a shorter time to recurrence among patients with a positive margin. CONCLUSIONS: In our study, among patients with positive surgical margins, those with multiple positive margins, or a margin involving the bladder neck or the posterolateral surface of the specimen carried a higher risk of progression. A positive margin at the bladder neck appears to be the most significant adverse prognostic indicator. This information may help in decisions regarding additional therapy.

Laparoscopic radical prostatectomy: technique.

Ongoing progress in laparoscopy has permitted extension of its indications for performance of complex oncologic and reconstructive surgeries such as radical prostatectomy. Laparoscopic radical prostatectomy is now feasible when performed by urologists trained in laparoscopy. Although the procedure is technically rewarding, it is more important to evaluate it in regards to efficacy. The short-term oncologic and functional efficacy rates (regarding urinary continence) seem equivalent to the rates for open surgery. Longer follow-up is needed to assess the preservation of potency with the laparoscopic technique. The integration and application of open nerve-sparing techniques to the laparoscopic approach should be feasible owing to the excellent visual accuracy at the prostatic apex. Initially, the operating time is lengthy (> 7 hours), but the length improves considerably with each series of 20 or more cases. Overall, the learning curve for laparoscopic radical prostatectomy is approximately 50 cases. Whether the laparoscopic approach will ever be as time efficient for the urologist as open radical prostatectomy remains to be seen. The authors' preliminary impression from the patient's perspective is that laparoscopic prostatectomy may offer significant advantages over open surgery in terms of the immediate postoperative quality-of-life concerns.

Postoperative radiotherapy after radical prostatectomy: a randomised controlled trial (EORTC trial 22911).

BACKGROUND: Local failure after prostatectomy can arise in patients with cancer extending beyond the capsule. We did a randomised controlled trial to compare radical prostatectomy followed by immediate external irradiation with prostatectomy alone for patients with positive surgical margin or pT3 prostate cancer. METHODS: After undergoing radical retropubic prostatectomy, 503 patients were randomly assigned to a wait-and-see policy, and 502 to immediate postoperative radiotherapy (60 Gy conventional irradiation delivered over 6 weeks). Eligible patients had pN0M0 tumours and one or more pathological risk factors: capsule perforation, positive surgical margins, invasion of seminal vesicles. Our revised primary endpoint was biochemical progression-free survival. Analysis was by intention to treat. FINDINGS: The median age was 65 years (IQR 61-69). After a median follow-up of 5 years, biochemical progression-free survival was significantly improved in the irradiated group (74.0%, 98% CI 68.7-79.3 vs 52.6%, 46.6-58.5; p<0.0001). Clinical progression-free survival was also significantly improved (p=0.0009). The cumulative rate of locoregional failure was significantly lower in the irradiated group (p<0.0001). Grade 2 or 3 late effects were significantly more frequent in the postoperative irradiation group (p=0.0005), but severe toxic toxicity (grade 3 or higher) were rare, with a 5-year rate of 2.6% in the wait-and-see group and 4.2% in the postoperative irradiation group (p=0.0726). INTERPRETATION: Immediate external irradiation after radical prostatectomy improves biochemical progression-free survival and local control in patients with positive surgical margins or pT3 prostate cancer who are at high risk of progression. Further follow-up is needed to assess the effect on overall survival.

The place of radical prostatectomy in the treatment of early localized prostate cancer.

Today a number of treatment options exist for men diagnosed with early localized prostate carcinoma, of which the most important are radical prostatectomy, external beam radiotherapy and brachytherapy. New advances in brachytherapy using the implantation of iodine-125 and palladium-103 seeds have significantly altered its place in the treatment of localized disease and provided an alternative to external beam radiotherapy and potentially radical prostatectomy. Drawing on recently published data and our own experiences of retropubic radical prostatectomy in 100 consecutive men with localized disease, we review the place of radical prostatectomy in the treatment of early prostate cancer today. For many urologists radical prostatectomy remains the treatment of choice for men aged 70 years or less, with localized disease, a life expectancy of over 10 years and no co-morbidity. However, this has to be balanced against recent advances in brachytherapy, which now provides a minimally invasive alternative therapy for some patients with organ-confined disease and for those in whom surgery is contraindicated.

[Transrectal ultrasonography in the assessment of patients after radical prostatectomy. Normal and pathologic ultrasonography anatomy of vesico-urethral anastomosis].

OBJECTIVE: To determine the ultrasound characteristics of the vesico-urethral anastomotic complex in patients with radical prostatectomy to separate normal prostate fossae from those affected by local recurrence or residual tumour. MATERIAL AND METHODS: Between January 1998 and June 1999 15 ultrasound guided transrectal biopsies of vesico-urethral anastomosis or prostate fossae were performed in patients with radical prostatectomy. The selection criteria to perform puncture in these patients were a negative extension study (abdominal-pelvic CT and bone scan), PSA higher than 0.4 ng/mL and/or suspicious DRE. The study was completed with 10 transrectal ultrasound (TRU) after radical prostatectomy in patients with normal PSA and DRE. TRU parameters in patients with tumour-positive biopsies were compare to those from patients with negative biopsies and those obtained from TRU in patients with both normal PSA and normal DRE. RESULTS: The ultrasound parameters that best described prostate fossa abnormalities were the presence of hypoechoic masses or nodes and the integrity or not of the retro-anastomotic fat layer. When a hypoechoic mass or node was found at the anastomosis level, 80% biopsies were positive for tumour local recurrence. The percentage increases when changes are seen at the retro-anastomotic fat layer. CONCLUSIONS: In spite of a good correlation between ultrasound abnormalities and positive biopsies, ultrasound findings from the vesico-urethral anastomosis in patients with radical prostatectomy are not well defined. Nodes or ultrasound irregularities can exist in normal prostate fossae as well as normal anastomosis ultrasound in the presence of tumoral relapses. We believe TRU of vesico-urethral anastomosis to be the best method available to evaluate local recurrence or tumoral persistence after radical prostatectomy.

[Prostate cancer recurrence after radical prostatectomy and salvage radiotherapy].

OBJECTIVE: To evaluate the efficacy of the radiotherapy to prostatic bed in patients with biochemical recurrence for prostate cancer after radical prostatectomy. MATERIAL AND METHODS: We analyse the results of 292 patients underwent radical prostatectomy for localized prostate cancer T1-T2 between January 1992 and June 2003, with an average folow-up of 36 months (range 6 months to 12 years). We detect biochemical recurrence (PSA >0.20 ng/ml) in 75 (26%) patients. Of 75 patients with biochemical recurrence, 9 (12%) was diagnosed of local recurrence by the following criteria: a) The first PSA obtained 6 weeks after radical prostatectomy <0.20 ng/ml. b) The time to biochemical recurrence >6 months. c) The prostate specific antigen doubling time >6 months. d) The prostate specific antigen velocity after radical prostatectomy <0.75 ng/ml/year. e) The prostate specific antigen level after radical prostatectomy <2.5 ng/ml. The 9 patients diagnosed of local recurrence received an average dose of 56.42 Gy in the prostate bed. RESULTS: Of all 9 patients with local recurrence, 7 (77.7%) has complete response with an average time of follow-up of 25 months (6-30 months). The time between the radiotherapy and the response, in patients with complete response, was lower than 3 months. Were not observed significant adverse effects associated to radiotherapy. CONCLUSIONS: The salvage radiotherapy may be beneficial in select patients with local recurrence. The characteristics of prostate specific antigen elevation are useful in distinguishing men with local recurrence from those with distant metastases.
