Postsurgical management of the patient undergoing radical prostatectomy.

Radical prostatectomy is a useful procedure for the treatment of prostate cancer limited to the gland; however, failure may occur as a result of the immediate or delayed complications of surgery, or to disease recurrence related to incomplete tumour excision. Seventy-nine radical prostatectomies were performed between April 1985 and August 1991 in patients with prostate cancer (primarily stage B1) who averaged 63 years of age. Immediate post-operative complications included vesicocutaneous fistulae, cystic lymphangiomas, abdominal wall abscesses, extraperitoneal haematoma, acute cholecystitis, and enterocutaneous fistula. Massive pulmonary embolism accounted for 2 deaths. Of the 77 surviving patients followed up for an average of 34 months, 79.2% (61) were continent, 15.6% had stress-related incontinence or severe incontinence and 5.2% were lost to follow-up. Sexual potency was preserved in 13 of the 33 patients (39%) who were pre-operatively potent. A favourable outcome as defined by no recurrence was seen in 69 patients (87.3%). Four patients (5.1%) are living with recurring prostatic cancer and 1 patient has died of the disease 46 months after surgery.

Radical prostatectomy 1972-1987 single institutional experience: comparison of standard radical prostatectomy and nerve-sparing technique.

During the period of time from 1972 to 1987 a total of 104 radical prostatectomies were performed at the Ohio State University. From 1972 to 1985, standard radical retropubic prostatectomy was done in 60 patients and from 1986 to June 30, 1987, radical retropubic nerve-sparing prostatectomy was carried out in 44 patients. Transrectal ultrasound evaluation was available only for three quarters of the patients in the latter group. In the early part of the series, standard prostatectomy revealed 51 percent of the patients to have organ-confined disease and in the latter series 75 percent had organ-confined disease. In the earlier study only a retrospective analysis of the pathology reports was available, and in the latter study prospective evaluation was available with regard to pre- and postoperative staging, erectile function, blood loss and replacement, PSA data, and clinical and pathologic staging. It appears the radical nerve-sparing prostatectomy has several advantages including decreased blood loss, increased reservation of erectile function in 70 percent of the patients who were potent preoperatively, and a more accurate assessment of clinical stage prior to surgery through the use of transrectal ultrasonography.

Male urethral sphincteric anatomy and radical prostatectomy.

Continence after radical prostatectomy is a multifactorial problem with no clear common denominator. At the heart of success is proper patient selection and operative skill in the precise dissection of the sphincteric anatomy. In general, surgeons who know the anatomy protect the patient by virtue of less blood loss, better margins of resection, and greater functional preservation.

Adjuvant radiation therapy in patients with detectable prostate specific antigen following radical prostatectomy.

Adjuvant radiation therapy following radical prostatectomy for adenocarcinoma of the prostate was given to 25 patients. Of these patients 8 had microscopic lymph node metastasis, 8 had seminal vesicle invasion without positive lymph nodes, 6 had positive surgical margins and 3 had only capsule penetration. Their only evidence of residual disease was detectable serum prostate specific antigen (PSA) by the Yang assay. A total of 15 patients (60%) had a subsequent decrease in PSA to less than 0.3 ng./ml. and an additional 5 (20%) had a decrease in PSA by more than 50%. Currently 8 patients have no detectable PSA after a median followup of 18 months (17 to 38 months) since initiating radiation therapy. Only 1 of 12 patients with detectable PSA immediately after radical prostatectomy has had a durable response to adjuvant radiation therapy. In contrast 7 of 13 patients with a delayed increase in PSA had a durable response. The ability of adjuvant radiation therapy to eliminate serum PSA in patients with a delayed increase in PSA after radical prostatectomy is encouraging. However, longer followup, including the use of nonradiated control subjects, is needed to assess the ability of adjuvant radiation therapy to control local disease and prolong patient survival.

Multivariate analysis of factors predicting local relapse after radical prostatectomy--possible indications for postoperative radiotherapy.

Between 1970 and 1983, 273 patients underwent radical surgery (radical prostatectomy--261, radical cystoprostatectomy--12) for newly diagnosed adenocarcinoma of the prostate at Duke University Medical Center and received no adjuvant radiotherapy. A total of 46 patients developed local recurrence. Forty developed local relapse only and six developed simultaneous local and distant failure. The crude local relapse rate was 17% (46/273). The actuarial local failure rate at 5, 10, and 15 years was 12%, 32%, and 35%, respectively. Univariate and multivariate analyses were performed to identify factors predictive of local relapse after radical surgery. Possible prognostic factors analyzed were: age, type of biopsy, use of adjuvant hormonal therapy, histologic grade, histologic involvement of seminal vesicles, positive surgical margins, clinical stage, and elevated acid phosphatase. Factors identified as significant predictors of local relapse by univariate analysis were: poorly differentiated histology (p = 0.0001), seminal vesicle involvement (p = 0.0009), and positive surgical margins (p = 0.0001). An elevated preoperative acid phosphatase was of borderline significance (p = 0.06). On multivariate analysis, poorly differentiated histology (p = 0.0007), positive margins (p = 0.0015), and elevated acid phosphatase (p = 0.0273) were significant predictors of local failure. Seminal vesicle involvement was no longer a significant predictor of local failure. However, on subsequent univariate and multivariate analyses, seminal vesicle involvement was the only significant predictor for the development of distant metastases (p = 0.0019, multivariate). Thus, patients with poorly differentiated tumors, positive surgical margins, or elevated preoperative acid phosphatase are at high risk for local relapse after radical prostatectomy. These patients should be included in future clinical trials studying the role of adjuvant radiotherapy after radical prostatectomy, or offered adjuvant radiotherapy if they cannot or will not participate in such trials.

Radical prostatectomy after definitive radiation therapy for prostate cancer.

Radical prostatectomy was performed in 14 patients following local failure of radiation therapy for adenocarcinoma of the prostate. Ten patients were treated with external beam and 4 with interstitial radiation. The interval from beginning radiation therapy to biopsy-proved residual or recurrent disease was twenty-four to one hundred fourteen months (mean 61 months). Ten patients had significant anterior and lateral fibrosis. Five patients had loss of tissue planes between the prostate and rectum, however, no rectal injuries occurred. Estimated blood loss was 300-8,000 cc (median 1,000 cc). Operative time was one hundred ten to three hundred seventy-five minutes (median 185 minutes). Significant late complications are impotence (100%) and incontinence (55%). Tumor volume was 1.1-27.2 cc (mean 11.1 cc). Seven patients had seminal vesicle involvement, 9 had level III capsule penetration, and 6 had positive surgical margins. Follow-up ranges from one to fifty-two months (median 18 months). Currently, 6 patients are clinically without disease and have serum prostate-specific antigen (PSA) of 0.0 ng/mL. Four patients have no clinical evidence of disease but do have detectable serum PSA, and 4 patients have evidence of metastatic bone disease on bone scan with elevated serum PSA levels. Radical prostatectomy following radiation therapy has no greater immediate morbidity or mortality compared with radical prostatectomy without prior irradiation and takes only slightly longer to perform. However, there is a marked increased risk of impotence and incontinence. More patients followed for a longer time are needed to assess the benefit of radical prostatectomy on survival of patients who fail radiation therapy.

[Urinary continence after radical prostatectomy: the urodynamic proof of an anatomical hypothesis (author's transl)].

Prostatic carcinoma can be cured by a radical operation. In radical prostatectomy the whole so-called internal sphincter is removed. It is generally accepted and often proved that the external sphincter which is mostly somatically innervated cannot resume the funciton of continence. The postoperative urinary incontinence after radical prostatectomy is frequent and therefore the radical prostatectomy is not performed in many places. The problem of postoperative continence as well as incontinence after enucleation of the adenoma will be briefly discussed. In 1966, HUTCH described the so-called 'baseplate'. It is a bundle of smooth muscle fibers, circulary arranged around the bladder neck, which are also responsible for passive continence. He proposed that a certain sphincter function can be achieved by a tubular anastomosis of this anatomical substratum with the distal urethral stump. We were able to prove this anatomical hypothesis urodynamically. A specially constructed double-lumen perfusion catheter enabled us to register the so-called functional urethra profile and simultaneously register a new sphincter pressure wave in the transformed 'baseplate' which was responsible for the continence. We could observe this new sphincter region in all continent patients after radical prostatectomy whereas in the incontinent patients it was absent. Since 1972 we have employed the procedure proposed by HUTCH and have performed 20 radical prostatectomies. All these patients have been postoperatively completely continent. We are of the opinion that undue restraint concerning radical prostatectomy is no more justified.

Can stage A1 tumor extent be predicted by transurethral resection tumor volume, per cent or grade? A study of 64 stage A1 radical prostatectomies with comparison to prostates removed for stages A2 and B disease.

We studied 64 totally embedded radical prostatectomy specimens of stage A1 prostate cancer. The transurethral resection specimens were studied and compared to previously studied stages A2 and B cancer in which tumor volumes also were calculated. At radical prostatectomy 6% of the specimens had no residual cancer, 74% had minimal cancer and 20% had substantial cancer. Although most stages A2 and B tumors were larger, there was overlap among all stages. Transurethral resection tumor volume, per cent and grade were not statistically correlated with either radical prostatectomy residual tumor volume, or whether tumor was classified as minimal or substantial. Gleason sum 2 to 4 versus 5 to 7 tumor on transurethral resection showed no difference in predicting radical prostatectomy residual tumor or minimal versus substantial tumor status. Because 20% of all stage A1 cancers have substantial tumor at radical prostatectomy unpredictable by transurethral resection, radical prostatectomy remains an option for young men with stage A1 prostate cancer.

Morbidity of pelvic lymphadenectomy and radical prostatectomy for prostatic cancer.

Radical retroperitoneal pelvic lymphadenectomy is associated with rather minimal morbidity but, when combined with radical prostatectomy, the morbidity is increased. The only complication that seemed to be solely owing to the lymphadenectomy was lymphocele formation, which occurred in 10 per cent of the patients. This rate is below that reported in the gynecologic-oncology literature.

[Radical prostatectomy: role of ultrasonography in the follow-up].

After a brief summary about surgical technique of radical prostatectomy and its indications in the different stages of prostatic cancer, the Authors describe complications and surgical sequelae of this operation. The Authors report a brief series. It is composed with 13 patients. Their have been submitted to radical prostatectomy for prostatic cancer between January 1989 and September 1991. Pathological stage was B1 in 6 patients, B2 in 2 patients, C1 in 4 cases and C2 in 1. Particularly the role of ultrasonography in detection and follow-up of early complications such as lymphocele, pelvic hematoma and anastomotic urine leakage is stressed. Transrectal ultrasound is especially useful in the detection of urine leakage from vesico-urethral anastomosis. This technique is compared with traditional cystourethrography and advantages and disadvantages of the two techniques are discussed. Later complications of radical prostatectomy are anastomotic stenosis, pelvic recurrences, nodal or parenchymal metastasis, urinary incontinence. The role of transrectal ultrasound in the detection of anastomotic strictures is stressed, especially when the study is done during micturition. Transrectal ultrasound is not so satisfying in the detection of pelvic recurrences, especially if they are smaller than 1 cm. In case of large masses digital examination is diagnostic itself. At last the Authors describe urinary incontinence and its etiology as a complication of radical prostatectomy. Particularly a surgical technique for vesico-urethral anastomosis proposed by Rocca Rossetti and its value in post-operative continence is described. The Authors show the results of transrectal ultrasound in the detection of striated urethral sphincter and its function after radical prostatectomy.

Radical prostatectomy: the pros and cons of the perineal versus retropubic approach.

Radical prostatectomy is frequently recommended for the treatment of localized adenocarcinoma of the prostate. The use of the perineal versus the retropubic approach is mostly dependent upon the experience of the individual surgeon. This study was performed to evaluate the short-term differences between the 2 operations. Between 1988 and 1989, 173 patients were identified with organ confined prostate cancer (stage A or B) who were treated with radical prostatectomy. Of this total population 122 patients underwent radical perineal prostatectomy (group 1) and 51 patients underwent radical retropubic prostatectomy (group 2). The median estimated blood loss for group 1 was 565 cc and for group 2 it was 2,000 cc (p less than 0.001). Group 1 received a median of 0 units of blood during hospitalization, while group 2 received a median of 3 units of blood (p less than 0.001). The total operative time was slightly shorter for group 1 but the anesthesia time was similar for both patient populations. There was no difference in the incidence of positive surgical margins, and in in-hospital and long-term complication rates between the 2 groups. In light of these significant findings it is our belief that the radical perineal prostatectomy is an excellent approach for the treatment of adenocarcinoma of the prostate.

Utilization of bone scans in conjunction with prostate-specific antigen levels in the surveillance for recurrence of adenocarcinoma after radical prostatectomy.

Follow-up evaluation of patients who have undergone radical prostatectomy routinely consists of serial bone scintigraphy and, more recently, prostate-specific antigen (PSA) levels. The utility of serial bone scans in combination with PSA levels is retrospectively reviewed in 118 men treated by radical prostatectomy for clinical Stage A or B disease who, at the time of surgery, had no evidence of metastatic disease. Of the 118 patients, 75.4% had no abnormality on either test (mean follow-up 32.4 mo), 9.3% demonstrated a detectable or rising PSA level with negative bone scan (mean follow-up 35 mo), and 8.5% exhibited a detectable and or rising PSA level and positive bone scan (mean follow-up 30.7 mo). Follow-up bone scans were read as either positive or indeterminate with undetectable PSA levels in 6.8% of patients (mean follow-up 27.3 mo). Critical review of the equivocal studies suggests that postoperative PSA levels more truly represent the clinical situation than bone scans. Following radical prostatectomy, routine bone scintigraphy provides little additional information when PSA levels are negative. If PSA becomes detectable or the patient develops symptoms, bone scintigraphy should then be performed.

Neo-adjuvant hormonotherapy does not facilitate radical prostatectomy.

Sixty-eight patients who underwent radical prostatectomy without or after neo-adjuvant hormonotherapy for B2 or C stage prostate cancer were evaluated as concerned to the ease of the surgical procedure. Although it is difficult to assess this parameter, we experienced more difficulties and blood loss was higher in patients who had preoperative hormonal deprivation. Ongoing randomized trials could demonstrate an oncological benefit of neo-adjuvant hormonotherapy before radical prostatectomy. This eventual benefit will have to be balanced against an increased surgical difficulty.

The effect of radiation therapy after radical prostatectomy in patients with elevated prostate specific antigen levels.

We analyzed the effects of pelvic radiation therapy given to patients who had an elevated prostate specific antigen level after radical prostatectomy. Among men who previously received adjuvant radiation therapy and had appropriately stored serum 15 had elevated prostate specific antigen levels after radical prostatectomy but before radiation therapy. After radiation therapy the prostate specific antigen level decreased by more than 50% in 80% and to female levels in 53% of the patients. We also prospectively treated 29 men who had increasing levels of prostate specific antigen 9 to 95 months after radical prostatectomy but who were otherwise without evidence of disease by the usual criteria. However, 19 of the patients had local disease as evidenced by random needle biopsy of the urethrovesical anastomosis. Complications of radiation therapy were minimal and maximal prostate specific antigen decrease occurred by 6 months after treatment. In 82% of the patients prostate specific antigen levels decreased by more than 50% and in 43% they decreased to female levels. Female levels were achieved after radiation therapy given many years postoperatively even in stage D1 cancer patients but some of the patients subsequently had increasing prostate specific antigen levels. These data suggest that local-regional disease may be the only site of disease persistence after radical prostatectomy in some of the patients who subsequently have distant metastasis. We conclude that radiation therapy after radical prostatectomy can cause elevated prostate specific antigen to decrease to undetectable levels in many patients but the durability and ultimate therapeutic value of this effect are unknown.

Evaluation of radical prostatectomy specimens. A comparative analysis of sampling methods.

We evaluated 104 radical prostatectomies for clinical stage B (n = 93) and stage A (n = 11) prostate cancer. Seven (8%) stage B cases had no gross cancer. By submitting only gross stage B cancer along with standard sections of proximal and distal margins, base of seminal vesicles, and most apical section (next to distal margin), we identified 91% of capsular penetration and 96% of positive margins as compared with identification by complete microscopic examination. Although this method identified 100% capsular penetration and positive margins in stage A cases, 28% of all the cases were grossly normal. Stage A tumor was often difficult to identify because of its heterogeneous location, its gross similarity to nodular hyperplasia, and the confounding presence of post-transurethral resection scarring. In 98% of all stages B and A cases, this method identified to within 1, the Gleason sum of the totally embedded radical prostatectomy. Using this sampling method, key pathologic parameters were identified with an average of 13 blocks (range 7-36) as compared with totally embedding the prostate, using an average of 42 blocks (range 21-81). Based on our study and our understanding of stages A and B disease, we recommend that in grossly normal glands, alternate posterior sections (stage B) and alternate entire sections (stage A) be submitted. Use of this sampling method will achieve a greater uniformity in the processing of specimens and a more accurate pathologic analysis of radical prostatectomy specimens.

Frequency and location of extracapsular extension and positive surgical margins in radical prostatectomy specimens.

Positive surgical margins have been reported with disturbing frequency in radical prostatectomy specimens and may portend an increased risk of eventual treatment failure. We determined the location of any cancer, extracapsular extension and positive surgical margins in 144 consecutive step-sectioned radical prostatectomy specimens. Of the 46 stage A cancer patients 98% had residual cancer in the prostate after transurethral resection and in 76% cancer was found posteriorly in the gland. Extracapsular extension was identified in 10 patients (22%): anteriorly in 5, posterolaterally in 5 and on the most apical transverse section in 4. Positive margins were found in 10 patients (22%) and half of these occurred posterolaterally. Of the 98 stage B cancer patients tumor was located posteriorly in 97%. Extracapsular extension was found in 62 patients (63%) and in 87% of these it was located posterolaterally. Positive margins were found in 23%, most commonly in the posterolateral and rectal areas (57% and 26%, respectively), and in more than half of these the positive margin resulted from incision into the capsule. In 18 of the 144 patients (13%) a single positive surgical margin was the only pathological indicator of treatment failure and half of these occurred in the area of the neurovascular bundle. Some of these patients with extraprostatic tumor might have been cured if wide excision of the neurovascular bundle had been performed. Overemphasis on preservation of potency during radical prostatectomy may leave some patients with persistent local disease.

Postoperative radiation therapy after radical prostatectomy for prostate carcinoma.

BACKGROUND: The role and benefit of adjuvant radiation therapy after radical prostatectomy is unclear. This role was evaluated in 58 patients who, after undergoing radical prostatectomy for prostate carcinoma, had local extension of disease beyond the prostate or positive surgical margins. Thirty-nine patients treated surgically alone were compared with 19 patients who received adjuvant postoperative radiation therapy. All patients were followed for at least 5 years, and 50 patients had 10-year follow-ups. RESULTS: At 10 years, the actuarial local failure rate was 31% for patients treated with prostatectomy alone versus 6% for the group receiving postoperative radiation therapy (P less than 0.05). The actuarial survival and metastasis-free survival were similar for both groups. When patients with involved lymph nodes were excluded from analysis, the addition of radiation therapy resulted in improved recurrence-free survival (91% versus 46% at 10 years, P = 0.04) and in a trend toward improved metastasis-free survival (91% versus 55%, P = 0.08). Complications occurred in similar frequencies in both groups. CONCLUSIONS: In patients with local disease extension or positive surgical margins after radical prostatectomy, adjuvant radiation therapy improved local control and was administered with acceptable side effects.

Prostate specific antigen and local recurrence after radical prostatectomy.

We evaluated the location of recurrent disease in 63 patients with carcinoma of the prostate who had abnormal levels of prostate specific antigen (greater than 0.4 ng./ml., Tandem-R assay) 6 to 240 months after radical prostatectomy but who were otherwise considered to be without evidence of disease. The evaluation involved physical examination including digital rectal examinations by 3 urologists, isotopic bone scans, computerized tomography scans of the abdomen and pelvis, cystoscopy, and random needle biopsies of the urethrovesical anastomotic area. In 6 patients metastatic disease to the bone and/or lymph nodes was found and local prostate cancer was discovered in 5. Among 57 patients without evidence of disease by the usual methods of evaluation needle biopsies of the anastomosis revealed local disease in 42%. No local disease was discovered in 30 post-radical prostatectomy patients with normal prostate specific antigen levels. There was a wide range of transrectally palpable contours after radical prostatectomy in patients with and without elevated prostate specific antigen levels. We conclude that prostate specific antigen but not digital rectal examination is an excellent early indicator of possible local recurrence after radical prostatectomy. Whether the prevalence of local disease after radical prostatectomy using prostate specific antigen levels and needle biopsies of the anastomosis is greater than heretofore has been appreciated will require further study.
