Abstract
BACKGROUND Radical prostatectomy reduces mortality among men with clinically detected localized prostate cancer, but evidence from randomized trials with long-term follow-up is sparse. METHODS We randomly assigned 695 men with localized prostate cancer to watchful waiting or radical prostatectomy from October 1989 through February 1999 and collected follow-up data through 2017. Cumulative incidence and relative risks with 95% confidence intervals for death from any cause, death from prostate cancer, and metastasis were estimated in intention-to-treat and per-protocol analyses, and numbers of years of life gained were estimated. We evaluated the prognostic value of histopathological measures with a Cox proportional-hazards model. RESULTS By December 31, 2017, a total of 261 of the 347 men in the radical-prostatectomy group and 292 of the 348 men in the watchful-waiting group had died; 71 deaths in the radical-prostatectomy group and 110 in the watchful-waiting group were due to prostate cancer (relative risk, 0.55; 95% confidence interval [CI], 0.41 to 0.74; P<0.001; absolute difference in risk, 11.7 percentage points; 95% CI, 5.2 to 18.2). The number needed to treat to avert one death from any cause was 8.4. At 23 years, a mean of 2.9 extra years of life were gained with radical prostatectomy. Among the men who underwent radical prostatectomy, extracapsular extension was associated with a risk of death from prostate cancer that was 5 times as high as that among men without extracapsular extension, and a Gleason score higher than 7 was associated with a risk that was 10 times as high as that with a score of 6 or lower (scores range from 2 to 10, with higher scores indicating more aggressive cancer). CONCLUSIONS Men with clinically detected, localized prostate cancer and a long life expectancy benefited from radical prostatectomy, with a mean of 2.9 years of life gained. A high Gleason score and the presence of extracapsular extension in the radical prostatectomy specimens were highly predictive of death from prostate cancer.

Abstract
BACKGROUND Radical prostatectomy reduces mortality among men with localized prostate cancer; however, important questions regarding long-term benefit remain. METHODS Between 1989 and 1999, we randomly assigned 695 men with early prostate cancer to watchful waiting or radical prostatectomy and followed them through the end of 2012. The primary end points in the Scandinavian Prostate Cancer Group Study Number 4 (SPCG-4) were death from any cause, death from prostate cancer, and the risk of metastases. Secondary end points included the initiation of androgen-deprivation therapy. RESULTS During 23.2 years of follow-up, 200 of 347 men in the surgery group and 247 of the 348 men in the watchful-waiting group died. Of the deaths, 63 in the surgery group and 99 in the watchful-waiting group were due to prostate cancer; the relative risk was 0.56 (95% confidence interval [CI], 0.41 to 0.77; P=0.001), and the absolute difference was 11.0 percentage points (95% CI, 4.5 to 17.5). The number needed to treat to prevent one death was 8. One man died after surgery in the radical-prostatectomy group. Androgen-deprivation therapy was used in fewer patients who underwent prostatectomy (a difference of 25.0 percentage points; 95% CI, 17.7 to 32.3). The benefit of surgery with respect to death from prostate cancer was largest in men younger than 65 years of age (relative risk, 0.45) and in those with intermediate-risk prostate cancer (relative risk, 0.38). However, radical prostatectomy was associated with a reduced risk of metastases among older men (relative risk, 0.68; P=0.04). CONCLUSIONS Extended follow-up confirmed a substantial reduction in mortality after radical prostatectomy; the number needed to treat to prevent one death continued to decrease when the treatment was modified according to age at diagnosis and tumor risk. A large proportion of long-term survivors in the watchful-waiting group have not required any palliative treatment. (Funded by the Swedish Cancer Society and others.).

Abstract
BACKGROUND In 2008, we reported that radical prostatectomy, as compared with watchful waiting, reduces the rate of death from prostate cancer. After an additional 3 years of follow-up, we now report estimated 15-year results. METHODS From October 1989 through February 1999, we randomly assigned 695 men with early prostate cancer to watchful waiting or radical prostatectomy. Follow-up was complete through December 2009, with histopathological review of biopsy and radical-prostatectomy specimens and blinded evaluation of causes of death. Relative risks, with 95% confidence intervals, were estimated with the use of a Cox proportional-hazards model. RESULTS During a median of 12.8 years, 166 of the 347 men in the radical-prostatectomy group and 201 of the 348 in the watchful-waiting group died (P=0.007). In the case of 55 men assigned to surgery and 81 men assigned to watchful waiting, death was due to prostate cancer. This yielded a cumulative incidence of death from prostate cancer at 15 years of 14.6% and 20.7%, respectively (a difference of 6.1 percentage points; 95% confidence interval [CI], 0.2 to 12.0), and a relative risk with surgery of 0.62 (95% CI, 0.44 to 0.87; P=0.01). The survival benefit was similar before and after 9 years of follow-up, was observed also among men with low-risk prostate cancer, and was confined to men younger than 65 years of age. The number needed to treat to avert one death was 15 overall and 7 for men younger than 65 years of age. Among men who underwent radical prostatectomy, those with extracapsular tumor growth had a risk of death from prostate cancer that was 7 times that of men without extracapsular tumor growth (relative risk, 6.9; 95% CI, 2.6 to 18.4). CONCLUSIONS Radical prostatectomy was associated with a reduction in the rate of death from prostate cancer. Men with extracapsular tumor growth may benefit from adjuvant local or systemic treatment.

Abstract
PURPOSE To prospectively evaluate the feasibility of magnetic resonance (MR) imaging with ferumoxtran-10 in patients with prostate cancer to depict lymph node metastases outside the routine pelvic lymph node dissection (PLND) area. MATERIALS AND METHODS The study was approved by the institutional review boards at all four hospitals; patients provided written informed consent. Two hundred ninety-six consecutive men (mean age, 67 years; range, 47-83 years) with prostate cancer and an intermediate-to-high risk for nodal metastases (prostate-specific antigen level >10 ng/mL, Gleason score >6, or stage T3 disease) were enrolled. MR lymphography of the pelvis was performed 24 hours after intravenous drip infusion of ferumoxtran-10. Positive nodes at MR lymphography were indicated to be inside or outside the routine dissection area (RDA). On the basis of MR lymphography computed tomographic (CT)-guided biopsy, routine PLND, or MR imaging-guided minimal extended PLND was performed. RESULTS MR lymphography findings were positive in 58 patients. Of these, 44 had histopathologic confirmation of lymph node metastases. In 18 of 44 patients (41%), MR lymphography findings showed nodes exclusively outside the RDA, which were confirmed with MR lymphography-guided extended PLND (n = 13) and CT-guided biopsy (n = 5). In another 18 patients (41%), positive nodes were located both inside and outside the RDA at MR lymphography. In these 18 patients, routine PLND was used to confirm the nodes inside the RDA (n = 11); CT-guided biopsy was used to confirm nodes outside the RDA (n = 7). In the remaining eight patients, MR lymphography findings showed only nodes inside the RDA, which was confirmed with PLND (n = 5) and CT-guided biopsy (n = 3). In 14 of the 58 patients (24%), there was no histologic confirmation. CONCLUSION In 41% of patients with prostate cancer, nodal metastases outside the area of routine PLND were detected by using MR imaging with ferumoxtran-10.

Abstract
BACKGROUND The benefit of radical prostatectomy in patients with early prostate cancer has been assessed in only one randomized trial. In 2005, we reported that radical prostatectomy improved prostate cancer survival compared with watchful waiting after a median of 8.2 years of follow-up. We now report results after 3 more years of follow-up. METHODS From October 1, 1989, through February 28, 1999, 695 men with clinically localized prostate cancer were randomly assigned to radical prostatectomy (n = 347) or watchful waiting (n = 348). Follow-up was complete through December 31, 2006, with histopathologic review and blinded evaluation of causes of death. Relative risks (RRs) were estimated using the Cox proportional hazards model. Statistical tests were two-sided. RESULTS During a median of 10.8 years of follow-up (range = 3 weeks to 17.2 years), 137 men in the surgery group and 156 in the watchful waiting group died (P = .09). For 47 of the 347 men (13.5%) who were randomly assigned to surgery and 68 of the 348 men (19.5%) who were not, death was due to prostate cancer. The difference in cumulative incidence of death due to prostate cancer remained stable after about 10 years of follow-up. At 12 years, 12.5% of the surgery group and 17.9% of the watchful waiting group had died of prostate cancer (difference = 5.4%, 95% confidence interval [CI] = 0.2 to 11.1%), for a relative risk of 0.65 (95% CI = 0.45 to 0.94; P = .03). The difference in cumulative incidence of distant metastases did not increase beyond 10 years of follow-up. At 12 years, 19.3% of men in the surgery group and 26% of men in the watchful waiting group had been diagnosed with distant metastases (difference = 6.7%, 95% CI = 0.2 to 13.2%), for a relative risk of 0.65 (95% CI = 0.47 to 0.88; P = .006). Among men who underwent radical prostatectomy, those with extracapsular tumor growth had 14 times the risk of prostate cancer death as those without it (RR = 14.2, 95% CI = 3.3 to 61.8; P < .001). CONCLUSION Radical prostatectomy reduces prostate cancer mortality and risk of metastases with little or no further increase in benefit 10 or more years after surgery.

Can digital rectal examination or transrectal ultrasonography biopsy findings predict the side of nodal metastasis in prostate cancer? Urol Oncol 2007; 26:25-30. [PMID: 18190826 DOI: 10.1016/j.urolonc.2006.12.019] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2006] [Revised: 11/28/2006] [Accepted: 12/05/2006] [Indexed: 11/23/2022]
Abstract
PURPOSE To assess the use of several preoperative parameters in predicting the side of pelvic lymph node metastasis in patients with prostate cancer. MATERIALS AND METHODS A retrospective chart review (January 1982 to February 2004) identified 106 men with pathology proven lymph node positive prostate cancer for whom complete medical records were available. RESULTS The median serum prostate-specific antigen at diagnosis was 11 ng/ml with the clinical stage T1C in 9 patients, T2 in 68, and T3 in 29. The Gleason score on transrectal ultrasonography (TRUS) biopsy was < or =6 in 13, 7 in 41, and > or =8 in 52. A total of 93 patients had documented pretreatment digital rectal examination (DRE) findings: 54 had a unilaterally suspicious DRE, and 31 had a bilaterally suspicious DRE. Of patients with a unilaterally positive DRE, 30 had ipsilateral lymph node metastasis, 16 contralateral, and 8 bilateral. DRE showed a 71% sensitivity and 29% false-negative rate in predicting the side of nodal metastasis. A total of 98 patients had documented TRUS biopsy findings: 37 had unilaterally positive TRUS biopsies and 61 bilaterally positive biopsies. Of patients with unilaterally positive TRUS biopsies, 20 had ipsilateral lymph node metastasis, 11 contralateral, and 6 bilateral. TRUS biopsies showed an 86% sensitivity and 14% false-negative rate in predicting the side of nodal metastasis. CONCLUSIONS DRE and TRUS biopsies do not accurately predict the side of pelvic lymph node metastasis and should not determine the extent of the pelvic lymphadenectomy.

Abstract
Surgical treatment of prostate cancer has seen many improvements in the past two decades, including laparoscopy, robotic surgery, and better assessment of quality of life and functional results. The limits of surgery for locally advanced disease and after failure of radiotherapy have been better defined, together with the roles of neoadjuvant and adjuvant treatment. Patients with clinically organ-confined prostate cancer, reasonable life expectancy, and little or no co-morbidity are the best candidates for radical prostatectomy. This chapter reviews the different technical options for the treatment of prostate cancer, with their respective indications and functional and oncological results.

Abstract
PURPOSE Radioisotope guided sentinel lymph node (SLN) dissection (SLND) for prostate cancer has been shown to increase the sensitivity of detecting early metastases in open pelvic lymph node dissection. We developed a technique that allows SLND to be performed by laparoscopy in conjunction with laparoscopic radical prostatectomy. MATERIALS AND METHODS In 71 consecutive patients SLND was performed by 1 surgeon preceding laparoscopic radical prostatectomy. Mean preoperative prostate specific antigen was 8.88 ng/ml (range 2.1 to 25.4). At 24 hours prior to surgery 3 ml (200 MBq) Tc labeled human albumin colloid were injected into the prostate gland under transrectal ultrasound guidance. An especially designed laparoscopic gamma probe was used to measure radioactivity during surgery. SLNs were identified and removed. If frozen section analysis showed metastases, extended pelvic lymph node dissection was performed. RESULTS Radioactivity was detected on 2, 1 and no sides in 50 (70.4%), 19 (26.7%) and 2 patients (2.8%), respectively. In 81 of the 142 pelvic side walls (54.7%) SLNs were exclusively outside of the obturator fossa. Histopathological examination showed metastases to SLNs in 9 patients (12.9%). Eight of the 11 detected metastases (72.7%) were outside of the obturator fossa. Lymph node metastases were exclusively found in Tc marked lymph nodes. Mean tumor size was 1.7 mm (range 0.2 to 3.9). CONCLUSIONS SLND is feasible by laparoscopy. It detects micrometastases outside of the obturator fossa in a significant number of patients. We noted that the transperitoneal approach allowing wide exposure and a gamma probe with a 90-degree lateral energy window is the most important factor to enable successful laparoscopic SLND.

Abstract
BACKGROUND In 2002, we reported the initial results of a trial comparing radical prostatectomy with watchful waiting in the management of early prostate cancer. After three more years of follow-up, we report estimated 10-year results. METHODS From October 1989 through February 1999, 695 men with early prostate cancer (mean age, 64.7 years) were randomly assigned to radical prostatectomy (347 men) or watchful waiting (348 men). The follow-up was complete through 2003, with blinded evaluation of the causes of death. The primary end point was death due to prostate cancer; the secondary end points were death from any cause, metastasis, and local progression. RESULTS During a median of 8.2 years of follow-up, 83 men in the surgery group and 106 men in the watchful-waiting group died (P=0.04). In 30 of the 347 men assigned to surgery (8.6 percent) and 50 of the 348 men assigned to watchful waiting (14.4 percent), death was due to prostate cancer. The difference in the cumulative incidence of death due to prostate cancer increased from 2.0 percentage points after 5 years to 5.3 percentage points after 10 years, for a relative risk of 0.56 (95 percent confidence interval, 0.36 to 0.88; P=0.01 by Gray's test). For distant metastasis, the corresponding increase was from 1.7 to 10.2 percentage points, for a relative risk in the surgery group of 0.60 (95 percent confidence interval, 0.42 to 0.86; P=0.004 by Gray's test), and for local progression, the increase was from 19.1 to 25.1 percentage points, for a relative risk of 0.33 (95 percent confidence interval, 0.25 to 0.44; P<0.001 by Gray's test). CONCLUSIONS Radical prostatectomy reduces disease-specific mortality, overall mortality, and the risks of metastasis and local progression. The absolute reduction in the risk of death after 10 years is small, but the reductions in the risks of metastasis and local tumor progression are substantial.

Abstract
PURPOSE We developed a preoperative nomogram for prediction of lymph node metastases in patients with clinically localized prostate cancer. MATERIALS AND METHODS The study was a retrospective, nonrandomized analysis of 7,014 patients treated with radical prostatectomy at 6 institutions between 1985 and 2000. Exclusion criteria consisted of preoperative androgen ablation therapy, salvage radical prostatectomy and pretreatment prostate specific antigen (PSA) greater than 50 ng/ml. Preoperative predictors of lymph node metastases consisted of pretreatment PSA, clinical stage (1992 TNM) and biopsy Gleason sum. These predictors were used in logistic regression analysis based nomograms to predict the probability of lymph node metastases. RESULTS Overall 5,510 patients with complete clinical and pathological information were included in the study. Lymph nodes metastases were present in 206 patients (3.7%). Pretreatment PSA, biopsy Gleason sum, clinical stage and institution represented predictors of lymph node status (p <0.001). Bootstrap corrected predictive accuracy of the 3-variable nomogram (clinical stage, Gleason sum and PSA) was 0.76. Inclusion of a fourth variable, which accounts for institutional differences in lymph node metastases, yielded an area under the receiver operating characteristics curve of 0.78. The negative predictive value of our nomograms was 0.99 when they predicted 3% or less chance of positive lymph nodes. CONCLUSIONS Using clinical information, we produced 2 calibrated and validated nomograms, which accurately predict pathologically negative lymph nodes in men with localized prostate cancer who are candidates for radical prostatectomy.

Abstract
BACKGROUND Radical prostatectomy is widely used in the treatment of early prostate cancer. The possible survival benefit of this treatment, however, is unclear. We conducted a randomized trial to address this question. METHODS From October 1989 through February 1999, 695 men with newly diagnosed prostate cancer in International Union against Cancer clinical stage T1b, T1c, or T2 were randomly assigned to watchful waiting or radical prostatectomy. We achieved complete follow-up through the year 2000 with blinded evaluation of causes of death. The primary end point was death due to prostate cancer, and the secondary end points were overall mortality, metastasis-free survival, and local progression. RESULTS During a median of 6.2 years of follow-up, 62 men in the watchful-waiting group and 53 in the radical-prostatectomy group died (P=0.31). Death due to prostate cancer occurred in 31 of 348 of those assigned to watchful waiting (8.9 percent) and in 16 of 347 of those assigned to radical prostatectomy (4.6 percent) (relative hazard, 0.50; 95 percent confidence interval, 0.27 to 0.91; P=0.02). Death due to other causes occurred in 31 of 348 men in the watchful-waiting group (8.9 percent) and in 37 of 347 men in the radical-prostatectomy group (10.6 percent). The men assigned to surgery had a lower relative risk of distant metastases than the men assigned to watchful waiting (relative hazard, 0.63; 95 percent confidence interval, 0.41 to 0.96). CONCLUSIONS In this randomized trial, radical prostatectomy significantly reduced disease-specific mortality, but there was no significant difference between surgery and watchful waiting in terms of overall survival.

Abstract
Clearly, pelvic lymphadenectomy can provide important staging information in the management of prostate cancer, but this benefit is counterbalanced by a modest increase in morbidity and the significant cost of the procedure. It is difficult to provide universal recommendations concerning the indications for pelvic lymphadenectomy. Part of the problem lies in the fact that urologists perform pelvic lymphadenectomy for several different reasons. Some surgeons perform pelvic lymphadenectomy to better counsel patients after radical prostatectomy about their risk for disease progression and for planning adjuvant radiotherapy or hormonal therapy. For these surgeons, preoperative clinical staging parameters do not exclude patients from pelvic lymphadenectomy, and frozen section analysis intraoperatively provides no useful information. Alternatively, the staging information from pelvic lymphadenectomy can be used to justify cancellation of the subsequent prostatectomy should regional spread of prostate cancer be identified, sparing the patient the morbidity of an unnecessary radical prostatectomy. With this approach, despite the false-negative rate of up to 30%, the expense of frozen section analysis seems justified. For this second group of surgeons, the problem becomes balancing the modest morbidity and cost of pelvic lymphadenectomy against the probability that nodal spread of prostate cancer will be missed if the procedure is omitted. The authors consider a greater than 4% risk for missing regional disease to be unacceptable in this setting. Following this assumption, Table 3 outlines parameters for clinical stage, Gleason score, and preoperative PSA within which pelvic lymphadenectomy is indicated. These recommendations are based on [table: see text] predictions from the Partin nomogram, which has been validated using a series of over 4000 patients. For the large number of patients with clinical T1c disease and a preoperative PSA less than 10 ng/mL, bilateral pelvic lymphadenectomy is indicated only if prostate biopsy identifies tumor of Gleason grade 4 or higher. For lower-grade tumors in this patient population, the risk for nodal metastasis was less than 5% in the Johns Hopkins and Mayo Clinic series of over 5800 patients with prostate cancer. For a large pool of patients, the several thousand dollar cost of pelvic lymphadenectomy and the risk for injury to the obturator nerves and vessels, the formation of lymphoceles, and chronic genital edema can be eliminated with low risk. A nomogram-based approach provides only a starting point for a decision analysis framework to determine whether the surgeon should perform lymphadenectomy at the time of radical prostatectomy because current nomograms predict only lymph node positivity. In a decision analysis framework, some patient and physician value is derived from a negative lymphadenectomy. Moreover, the morbidity associated with pelvic lymphadenectomy and the potential inconvenience associated with treating such morbidity also would be factored into the decision. Consequently, a decision analysis framework that takes into account prognostic value, costs, morbidity, and health state uses ultimately will provide the most informative method for determining when pelvic lymphadenectomy is indicated in patients with prostate cancer.

Abstract
Involvement of the pelvic lymph nodes in patients with prostate cancer worsens the overall prognosis of this common disease entity. Prior radiographic staging techniques, including fine-needle aspiration, are limited by a poor sensitivity and are not reliable. The gold standard for the evaluation of pelvic lymph nodes in men with prostate cancer involves performing a lymphadenectomy. Historically, this procedure was performed using an open surgical technique. Unfortunately, this invasive procedure is associated with significant morbidity. In response, modern surgical technology has provided newer, less invasive techniques, including laparoscopic pelvic lymphadenectomy (LPLND). Improved detection of localized prostate cancer through the institution of screening protocols and early detection programs has decreased the number of patients presenting with lymph node involvement. Various clinical indicators, including prostate-specific antigen, grade, and stage, have been used to improve the selection of "high-risk" patients that are appropriate candidates for pelvic lymph node dissection. The technique of LPLND is a valid option in the armamentarium for staging of prostate cancer. The laparoscopic approach provides the same staging accuracy as the open surgical technique and is superior with respect to morbidity. LPLND is limited to patients who present with a high risk of advanced prostate cancer. In addition, the urologist must accept the additional training, financial expense, and "learning curve" associated with this technique.

Abstract
BACKGROUND To clarify the implications and limitations of external beam radiation monotherapy for localized prostate cancer, the long-term outcomes and prognostic factors were investigated. METHODS Between 1976 and 1994, 91 patients with untreated prostate cancer were treated with external beam radiation therapy alone. Thirty-two were classified as T1b, eight were T2a, four were T2b and 47 were T3. Pelvic lymphadenectomy was carried out in 69 cases; 57 were staged as pN0, eight were pN1, four were pN2 and 22 were pNX. Linac X-rays were used in 55 cases, fast neutron in 15 and a combination of the two in 21. No other therapy was given until relapse and when relapse was evident endocrine therapy was started. RESULTS The observation period ranged from 3 to 206 months with a median of 78 months. Local control rate and disease-free, cause-specific and overall survivals at 10 years were 74.0, 49.6, 74.2 and 39.2%, respectively. By univariate analysis, T category, pN category and histologic grade were significant prognostic indicators for disease-free survival. Multivariate analysis revealed that T category was an independent prognostic factor. In T2b and T3 diseases, pN0/1 patients demonstrated significantly better disease-free survival than pNX. CONCLUSIONS A favorable long-term outcome was achieved by external beam radiation monotherapy in patients with minimally extended prostate cancer (T1b and T2a). For locally advanced disease (T2b and T3), staging pelvic lymphadenectomy would be useful for the selection of patients.

Abstract
OBJECTIVES To improve the treatment of locally advanced prostate cancer (Stages B2 and C), a prospective randomized trial was conducted to compare radical prostatectomy versus external beam radiotherapy with the combination of endocrine therapy in both modalities. METHODS One hundred patients were enrolled and 95 were evaluated. Forty-six patients underwent radical prostatectomy with pelvic lymph node dissection, and 49 were treated with radiation by linear accelerator with 40 to 50 Gy to the whole pelvis and a 20-Gy boost to the prostatic area. For all patients, endocrine therapy was initiated 8 weeks before surgery or radiation, and continued thereafter. The living patients were asked to respond to a quality-of-life questionnaire. RESULTS The follow-up period ranged from 6.0 to 94.4 months (median 58.5). The progression-free and cause-specific survival rates at 5 years were 90.5% and 96.6% in the surgery group and 81.2% and 84.6% in the radiation group, respectively. The surgery group had better progression-free and cause-specific survival rates (P = 0.044 and 0.024, respectively). More patients in the surgery group complained of urinary incontinence. The questionnaire revealed that quality of life was less disturbed in the radiation group. CONCLUSIONS Radical prostatectomy combined with endocrine therapy may contribute to the survival benefit of patients with locally advanced prostate cancer. External beam radiotherapy in combination with endocrine therapy can be used in selected patients because of its low morbidity.

Abstract
OBJECTIVES The sites of recurrent carcinoma of the prostate were localized with radiolabeled monoclonal antibody, and these sites were correlated with the response of patients treated with pelvic radiation after prostatectomy. METHODS Radionuclide scans were performed with indium 111-labeled CYT-356, a monoclonal antibody that binds to prostate epithelial cells, in 48 men diagnosed with recurrent carcinoma detected by prostate-specific antigen (PSA) screening after radical retropubic prostatectomy. RESULTS In 48 patients with recurrent carcinoma detected by PSA screening following radical retropubic prostatectomy, 73% had monoclonal antibody activity beyond the prostatic fossa, and only 3 patients (6%) had activity in the prostatic fossa alone; 65% had monoclonal antibody activity in pelvic lymph nodes despite the fact that lymph node dissections were pathologically negative at the time of prostatectomy in 90% of the patients; and 23% of patients had monoclonal antibody activity in abdominal and extrapelvic retroperitoneal nodes. Of 48 patients, 13 underwent external beam radiation therapy after monoclonal antibody scans. Six patients had scans showing activity beyond the field of radiation, and radiation therapy failed in 4 of these patients. Seven patients had scans with no activity beyond the field of radiation therapy, and radiation therapy failed in only 2 of these patients. CONCLUSIONS The scans frequently show monoclonal antibody uptake in pelvic, abdominal, and extrapelvic retroperitoneal sites beyond the region of limited obturator node dissections and may account for the understaging and subsequent failure of radical prostatectomy in some patients. The monoclonal antibody scan seems to be a good predictor of which patients will respond to radiation therapy after radical prostatectomy, but because these patients often have nodal activity beyond the radiated field, this initial response may not be curative.

Abstract
BACKGROUND Laparoscopic pelvic lymphadenectomy (LPLND) can be performed safely and with minimal morbidity in the staging of prostate cancer. Its utility in evaluating patients at high risk for metastatic disease before primarily nonsurgical treatment modalities was evaluated. METHODS Twenty-four consecutive patients who underwent LPLND between June 1993 and July 1996 were studied. These patients were considered poor surgical candidates based on several risk factors, as follows: elevation of serum PSA >20 in 19 patients (79%); elevation of serum acid phosphatase in 4 patients (17%); digital rectal examination findings indicative of extraprostatic extension or seminal vesical involvement in 14 patients (58%); and poorly differentiated tumors on prostate biopsy in 19 patients (79%). Nineteen patients (79%) had two or more of these risk factors. Median PSA for the entire series of patients was 35.2 ng/mL (range 7.9 to 133 ng/mL), and median Gleason score was 7 (range 5 to 9). Preoperative CT or MRI was negative for pelvic lymph node metastases in 17 of 23 patients (79%), and bone scan was negative in all 24 patients. RESULTS Unilateral (n = 2) or bilateral (n = 22) LPLND was performed in all patients. Six patients (25%) had lymph node metastases detected laparoscopically. Five of the six patients had palpable extraprostatic extension (T3a/b) or invasion of a seminal vesical (T3c), and in four of these patients the site of the metastatic lymph nodes was ipsilateral to the palpable prostate abnormality. None of the risk factors was independently predictive of lymph node metastases within this series of patients. An average of 10.8 +/- 6.5 lymph nodes was removed at a mean operative time of 174 +/- 10 minutes for patients undergoing bilateral LPLND. Estimated blood loss was minimal for 20 of 22 patients (92%) undergoing LPLND alone, and there were no complications requiring open exploration. Mean postoperative hospital stay was 1.2 +/- 0.5 days for patients undergoing LPLND alone. CONCLUSIONS LPLND can be used efficiently to identify patients with nodal metastases from select high-risk patients. This, in turn, can exclude such patients from noncurative local and regional therapy.

Abstract
A good staging system should be able to accurately reflect the natural history of a malignant disease, to express the extent of the disease at the time of diagnosis, and stratify patients in prognostically distinctive groups. The staging system for prostate cancer, as it is today, fails to fulfill these requirements. Approximately one third of the patients who undergo surgery for complete excision of prostate cancer in fact do not have a localize disease. The incidence of tumor at the inked margin may reach 30% for T1 stage and up to 60% for clinical T2b prostate cancer according to comparison with pathologic examination of resected specimen. Several concepts have been recently proposed as a means of improving the accuracy of the available staging system. In this paper, we review current aspects of clinical and pathological staging of prostate cancer, and the importance of these new concepts on the early stages of prostate cancer.

Abstract
PURPOSE We evaluated the efficacy of a totally extraperitoneal approach to endoscopic pelvic lymph node dissection. MATERIALS AND METHODS Extraperitoneal endoscopic pelvic lymphadenectomy was performed in 125 patients with clinically localized prostate cancer. All patients were candidates for brachytherapy, cryotherapy or radical perineal prostatectomy. The first 65 patients underwent lymphadenectomy regardless of local clinical stage, prostate specific antigen (PSA) or tumor grade. The last 60 patients met 2 of 3 selection criteria, consisting of clinical local stage T2b or greater, prostate specific antigen greater than 20 and Gleason score 7 or higher. Patients were evaluated for morbidity and mortality, nodal yield, operative time, conversion rate to transperitoneal laparoscopic or open lymphadenectomy and hospital stay. RESULTS Mean operative time was 104 minutes, mean length of stay was 2.1 days and mean nodal yield was 10.2. Of the patients 19.2% had positive nodes, and positive nodal yield increased to 32.9% when selection criteria were used. Of the cases 4% were converted to a transabdominal laparoscopic approach and 2.4% to open lymphadenectomy. Symptomatic lymphoceles required percutaneous drainage in 2.4% of the patients. One patient died of massive pulmonary embolism. CONCLUSIONS This study demonstrates that the extraperitoneal endoscopic pelvic lymph node dissection is an effective and relatively safe method of surgically staging prostate cancer. It compares favorably to other methods of surgical staging.

Abstract
PURPOSE We compared the results of extended (obturator, hypogastric, common and external iliac nodes) to modified (obturator and hypogastric nodes only) laparoscopic pelvic lymph node dissection in patients with clinically localized prostate cancer. MATERIALS AND METHODS A total of 189 patients with stage T1 to T3 prostate cancer underwent modified (150) or extended (39) laparoscopic pelvic lymph node dissection for pelvic nodal assessment before definitive treatment. RESULTS Twice as many lymph nodes were removed via extended than modified laparoscopic pelvic lymph node dissection (mean 17:8 versus 9.3). The overall positivity rate was 23 of 189 lymph nodes (12.2%), including 14 of 150 (7.3%) for modified and 9 of 39 (23.1%) for extended dissection (p = 0.02). Two patients (22%) who underwent extended dissection had positive lymph nodes in the external iliac area. Patients who presented with the high risk features of prostate specific antigen (PSA) greater than 20 ng./ml., Gleason score 7 or greater, or stage T2b disease or greater had a 26.5% (p = 0.0002), 22% (p = 0.0006) or 16.4% (p = 0.003) likelihood of positive lymph nodes, respectively. For extended versus modified laparoscopic pelvic lymph node dissection node positivity in high risk patients was 27% versus 18.8% (p = 0.4), 30 versus 26.4% (p = 0.8) and 25.4 versus 14.6% (p = 0.17) for Gleason score 7 or greater, PSA greater than 20 ng./ml. and disease stage T2b to T3a, respectively. Patients who underwent the extended procedure had a higher complication rate (35.9 versus 2%, p < 0.0001). No laparotomy was required. CONCLUSIONS Despite yielding a 2-fold higher node count and higher node positivity rate, extended laparoscopic pelvic lymph node dissection offers no advantage over modified laparoscopic pelvic lymph node dissection for diagnosing positive lymph nodes when results are analyzed by prognostic factors. The extended procedure is associated with a much higher complication rate. In patients with the high risk features of PSA greater than 20 ng./ml., Gleason score 7 or greater and stage T2b to T3a disease modified laparoscopic pelvic lymph node dissection can be performed safely and effectively to help identify those who may benefit most from curative therapy.

Abstract
PURPOSE Prostate cancer clinical staging methods and decision support tools were reviewed to assess their accuracy to predict pathological staging results and determine what comprises an appropriate clinical staging evaluation. MATERIALS AND METHODS The MEDLINE data base was searched and 238 abstracts were obtained. Data were extracted from 142 articles that evaluated the preoperative accuracy of digital rectal examination, prostate specific antigen, prostatic acid phosphatase, systematic biopsy parameters (including Gleason scoring), seminal vesicle biopsy, various imaging studies and pelvic lymphadenectomy versus pathological staging results. The sensitivity, specificity and accuracy rates were calculated and tabulated from the reported data on each method or decision support tools for organ confined, nonorgan confined and lymph node metastatic tumor. RESULTS Decision support tools based on logistic regression analysis, which combine several statistically independent staging parameters, had greater accuracy than any single clinical staging method alone. The most accurate decision support tools for clinical staging combined digital rectal examination (T stage), systematic biopsy parameters (including Gleason scoring) and prostate specific antigen. CONCLUSIONS The components that comprise the most accurate decision support tools for clinical staging represent an appropriate staging evaluation for the newly diagnosed prostate cancer patient in 1997. Limited use of radiographic imaging and seminal vesicle biopsy may be indicated in select patients to detect bone metastases, and plan pelvic lymphadenectomy and surgical therapy.

Abstract
CT Scan, MR Imaging Scan, and Pedal Lymphangiography. Patients with a PSA greater than 25 ng/mL, a Gleason score greater than 6, and a positive DRE should undergo CT scan with FNA of lymph nodes at least 6 mm in size. Otherwise, CT scan, MR imaging scan, and pelvic lymphangiogram are not indicated. This should eliminate use of these staging studies in over 90% of patients with newly diagnosed adenocarcinoma of the prostate. Pelvic Lymph-Node Dissection. Pelvic lymph-node dissection can be safely eliminated in patients who meet the following predictive criteria: 1. PSA not more than 5 ng/mL or 2. Gleason score not more than 5 or 3. A combination of the following: PSA not more than 25 ng/mL, Gleason score not more than 7, and negative DRE. Following these criteria should eliminate the need for pelvic lymphadenectomy in 60% of patients with newly diagnosed prostate cancer.

Abstract
We report a new method for lymphadenectomy, the minilaparotomy (inguinal) pelvic lymph node dissection (MLPLND), and compare it with laparoscopic pelvic lymph node dissection (LPLND) in terms of cost, effectiveness, operation time and morbidity. We reviewed a series of 111 consecutive patients: 51 had MLPLND and 60 had LPLND. All patients had proved adenocarcinoma of the prostate by biopsy. Of the MLPLND patients, only 1 had to stay overnight in the hospital, and all left within 24 hours. Pelvic lymphadenectomy consisted of nodal removal along the internal iliac vessels and the external iliac vein, and nodes of the obturator foramen. A total of 14% of the patients had disease involving the lymph nodes. The cost of MLPLND was 50% of the cost of LPLND, with no interoperative or postoperative morbidity. This new operation can be performed thoroughly an inexpensively in approximately 35 minutes, with little or no morbidity. Since the drawbacks of laparoscopic techniques associated with instrument costs and the learning curve for this technically difficult operation are eliminated, staging pelvic lymphadenectomy can be performed routinely on a wider variety of patients with potential metastatic disease. Currently, we recommend MLPLND to any patient with a tumor of Gleason score 7 or higher or a serum prostate-specific antigen value of 15 ng/mL or higher.

Abstract
Laparoscopic surgical techniques were originally applied to the staging of prostate cancer in the form of laparoscopic pelvic lymph node dissection. The efficiency of laparoscopic pelvic lymph node dissection has proven to be comparable to open lymphadenectomy in tissue yield and also shows a considerable decrease in postoperative morbidity. Subsequently, laparoscopy has been used as an adjuvant to perineal prostatectomy for preliminary dissection of the seminal vesicles. Laparoscopic radical prostatectomy has been performed but the long-term efficacy of this treatment is unknown at this point. Future clinical applications of laparoscopic surgical techniques in the diagnosis and treatment of prostate cancer include harvesting of primary and metastatic prostatic tissue for adjuvant gene therapies for prostate cancer.

Abstract
PURPOSE Statistical models using preoperative Prostate-Specific Antigen, Gleason primary grade or score of the biopsy specimen, and clinical stage have been developed to predict those patients with clinically localized prostate cancer at low risk for lymph node metastasis. It has been recommended that these patients do not require pelvic lymph node dissections. Four such models were evaluated to assess their accuracy in identifying this subgroup of patients. METHODS AND MATERIALS We reviewed the records of 214 patients with clinically localized prostate cancer who underwent pelvic lymph node dissections. Data from these patients were entered into the four models. RESULTS Lymph node metastasis was detected in 14% of patients. The results showed the following for each of the proposed models respectively: 78, 50, 76, and 42% of the patients were identified as low risk and, hence, would be spared pelvic lymph node dissections. The false negative rates are 13 (7.8%), 5 (4.6%), 14 (8.6%), and 1 (1.1%). Sensitivities are 56.7, 83.3, 53.3, and 96.7%. CONCLUSIONS While the pelvic lymph node dissection is the most accurate method of detecting occult nodal metastasis, statistical models can identify a cohort of low risk patients that may be spared lymphadenectomy.

Abstract
PURPOSE The purpose of this study was to identify pretherapy factors associated with pelvic lymph node involvement (LNI) in patients with localized prostatic carcinoma (CaP), and to develop a model that would allow for estimation of this risk at the time of initial diagnosis. METHODS AND MATERIALS Between January 1988 and December 1992, 2439 patients with clinical Stage T1a-3cN0-XM0 CaP underwent radical retropubic prostatectomy and bilateral pelvic lymph node dissection as sole initial therapy at a single medical institution. Preoperative factors were evaluated for their association with pelvic LNI in univariate and multivariate logistic regression analysis. A model was developed that incorporated independent predictive variables, and probability plots were generated to estimate the likelihood of pelvic LNI in the patient with a new diagnosis of localized CaP. RESULTS Within clinical tumor stage, three groups (Tla-2a, T2b-c, and T3) were identified in which the observed rate of pelvic LNI was distinctly different. Gleason primary grades were also combined (1-2, 3, and 4-5) because of a similar observation. Univariate analysis identified clinical tumor stage (p < 0.0001), Gleason primary grade (p < 0.0001), and serum prostate-specific antigen (p < 0.0001) as factors associated with pelvic LNI. Each of these variables retained independent significance (p < or = 0.0002) in the multivariate model. Patient age (p = 0.12) and history of prior transurethral resection of the prostate (p = 0.36) were not found to correlate with this endpoint. Probability plots provided an estimate of the likelihood for pelvic LNI according to the combination of pretherapy clinical tumor stage, Gleason primary grade, and serum prostate-specific antigen level. CONCLUSION Clinical tumor stage as determined by digital rectal examination, Gleason primary grade of the diagnostic biopsy specimen, and pretherapy serum prostate-specific antigen value can be combined to estimate the probability of pelvic LNI for the patient with a new diagnosis of localized CaP. This information may be of value in directing the pretherapy diagnostic evaluation, as an aid in radiation therapy treatment planning, and in the conduct of clinical research efforts.

Abstract
OBJECTIVES This report assesses the feasibility of laparoscopic pelvic lymphadenectomy in irradiated patients with prostate cancer being considered for salvage therapy. METHODS Six men, each with a prior history of external beam radiation therapy, and prostate-specific antigen or clinical failure, were selected as potential candidates for salvage therapy. Utilizing a standard diamond pattern trocar conformation, laparoscopy was performed to evaluate pelvic lymph node status. RESULTS The procedure was successfully completed in all patients with a mean operating room time of 154 minutes. Blood loss averaged 55 cc. Serious intraoperative or postoperative complications were not encountered in the follow-up of 6 months. Metastatic disease was demonstrated in 1 patient. CONCLUSIONS Laparoscopic pelvic lymph node dissection is technically feasible in patients who have received irradiation, and appears to confer no additional morbidity over standard laparoscopic lymphadenectomy.

Abstract
OBJECTIVES To provide a risk-to-benefit analysis of open staging pelvic lymph node dissection (PLND) for prostate cancer. METHODS The medical records of all patients presenting with prostate cancer from July 1989 to April 1994 were reviewed. A total of 245 patients with clinically localized disease were selected to undergo radical retropubic prostatectomy (RRP) preceded by open PLND. Univariate and multivariate analyses were performed to evaluate the predictive value of the preoperative serum prostate-specific antigen (PSA) concentration, clinical stage, and Gleason score with regard to final nodal status. The cost and morbidity associated with PLND in the setting of RRP was also defined. RESULTS Overall, only 16 patients (6.5%) had lymph node metastases. Lymph node involvement correlated significantly with elevated serum PSA values (P = 0.0001), high Gleason score (P = 0.0022), and advanced clinical stage (P = 0.0001). Lymph node metastases were particularly uncommon in patients with nonpalpable tumors (1 of 67 [1.5%]), PSA values less than 10 (2 of 154 [1.3%]), and Gleason score less than 6 (1 of 26 [3.8%]). Overall, 179 patients (73.1%) presented with at least one or more of these favorable characteristics, and only 4 (2.2%) had lymph node involvement. Complications related to the lymphadenectomy occurred in 10 patients (4.1%). The cost per metastasis diagnosed in patients with low-risk characteristics was approximatley $43,600. CONCLUSIONS An open staging PLND may no longer be justified on a routine basis in patients undergoing radical retropubic prostatectomy.

Abstract
The result of 33 laparoscopic obturator lymph node dissections in patients with locally confined prostatic cancer are presented and compared with open surgery dissections. The hospitalization time was 3 days with the laparoscopic technique, a reduction by 50% compared with open surgery. The operation time was increased from 60 to 100 minutes. No serious complications were encountered. The postoperative recovery was fast and uneventful. The number of glands dissected out was slightly lower than that at open surgery. Obturator lymph node metastases were found in 15% of the patients in the laparoscopic series.

Abstract
Current treatment of prostate cancer is highly controversial, however accurate assessment of pelvic lymph node status is important to determine early in the course of therapy if adjuvant hormonal ablation is necessary. Indications for laparoscopic assessment of pelvic lymph nodes are now better defined and the technique requires a high degree of technical skill and expertise. A series of 50 patients who underwent laparoscopic pelvic lymphadenectomy is presented. A greater than 40% chance of node positivity was found in a group of patients who had either a clinical stage B2, C, DO, or a prostate-specific antigen level greater than 40 ng/dl, or a total Gleason score of 7, 8, 9, or 10. Laparoscopic pelvic lymphadenectomy remains the current method to accurately stage lymph node involvement in prostate carcinoma.

Abstract
To evaluate the usefulness of external beam radiotherapy for patients with prostate cancer confined to the pelvis, long-term results and prognostic factors were analyzed. During the period 1975-1989, 44 cases were treated with staging pelvic lymphadenectomy followed by monotherapy using external beam irradiation by Linac X-ray and/or fast neutrons and observed without any treatment until relapse was evident. All patients were followed until death or for a mean of 78.6 mo (range: 36-113 mo) for patients still alive. Four cases died of prostate cancer at 26, 28, 54, and 83 mo from the start of radiation. Eleven cases died of other causes (10-72 mo, mean 36.4 mo). Fourteen cases (31.8%) manifested clinical relapse of cancer; 4 had local relapse, 7 developed bone metastases, and 3 relapsed at lymph nodes. After relapse, endocrine therapy was effective in most cases. The five-year disease-free survival rates of pN0 (32 cases) and pN1 (8 cases) patients were 79.8% and 52.5%, respectively, but that of pN2 (4 cases) was worse. Cause-specific survival was similar between patients with pN0 and pN1 disease, the rate at 5 yr being 92.5% in the former and 100% in the latter. Those with high levels of serum prostate specific antigen (PSA) before treatment and advanced local disease (clinical stage C) showed unfavorable prognoses. The number of argyrophilic nucleolar organizer regions (AgNORs) might be a predictive factor in patients treated with irradiation. In conclusion, prostate cancer patients with stage A2-C, diagnosed as pN0-1 by staging pelvic lymphadenectomy, were successfully treated with external beam radiotherapy.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The sensitivity and accuracy rate of computerized tomography (CT) in lymph node staging of localized prostatic carcinoma is commonly considered to be low. Fine needle aspiration cytology of pathological lymph nodes seen on radiological staging can enhance this low accuracy rate. We prospectively investigated the accuracy of CT and fine needle aspiration cytology in lymph node evaluation of 285 patients with clinically locally confined prostatic carcinoma. The sensitivity, specificity and accuracy rates of this combined method were 77.8%, 100% and 96.5%, respectively. False-negative staging results were found in only 10 patients with minimal nodal disease. Although in contrast with previous reports, combined CT and fine needle aspiration cytology in our hands seems to be a highly efficient staging method for lymph node involvement. This method could be considered as an alternative to surgical lymphadenectomy in the preoperative evaluation of the nodal status of patients with localized prostatic carcinoma who are scheduled for radical prostatectomy or curative radiotherapy.
