Early growth response-1 gene: potential radiation response gene marker in prostate cancer

This study was undertaken to determine whether the transcription factor EGR-1 expression: (1) in the primary tumor, correlates with radiation response in terms of complete local tumor control with no evidence of disease or recurrence and no evidence of metastasis; (2) in the postirradiated biopsies correlates with residual tumor; and (3) correlates with the expression of Egr-1 target genes such as TP53, pRB, and Bax. The authors analyzed: (1) 25 pretreated surgically resected paraffin-embedded primary adenocarcinomas of the prostate for the presence of EGR-1 expression and mutation, and correlated this with clinical endpoints such as serum prostate-specific antigen levels and current clinical status; (2) 27 postirradiated biopsies of prostate for the presence of EGR-1 expression, and correlated these findings to the residual tumor status; and (3) 12 prospective prostate tumor specimens for EGR-1 expression and its target genes. EGR-1 expression was determined by immunohistochemistry and mutations were screened in two regions of the Egr-1 gene (trinucleotide AGC repeats in transactivation domain [TD] and poly A tract in 3'UTR) by polymerase chain reaction-single strand conformational polymorphism analysis. Of 25 patients, 18 patients showed expression of EGR-1. EGR-1 overexpression correlated with treatment failure. No correlation with EGR-1 overexpression and its target genes was found, which may indirectly suggest that overexpressed EGR-1 may lack transactivation function. In summary, EGR-1 overexpression in the mutant form may provide an indication of clinical failure (local recurrence or metastasis).

Bladder cancer clinical guidelines panel summary report on the management of nonmuscle invasive bladder cancer (stages Ta, T1 and TIS). The American Urological Association

PURPOSE

The American Urological Association convened the Bladder Cancer Clinical Guidelines Panel to analyze the literature regarding available methods of treating nonmuscle invasive bladder cancer, and to make practice policy recommendations based primarily on treatment outcomes data.

MATERIALS AND METHODS

The panel searched the MEDLINE database for all articles related to nonmuscle invasive bladder cancer published from 1966 to January 1998. Outcomes data were extracted from articles accepted after panel review and meta-analyzed to produce comparative probability estimates for alternative treatments.

RESULTS

All of the intravesical agents (thiotepa, bacillus Calmette-Guerin, mitomycin C and doxorubicin) when used as adjuvant therapy after transurethral resection resulted in a lower probability of recurrence compared to resection alone. However, there is no evidence that intravesical therapy affects long-term progression.

CONCLUSIONS

For patients with no prior intravesical therapy adjuvant intravesical chemotherapy or immunotherapy is a treatment option after endoscopic removal of low grade Ta bladder cancers. Intravesical instillation of bacillus Calmette-Guerin or mitomycin C is recommended for carcinoma in situ, and after endoscopic removal of T1 and high grade Ta tumors.

Combined post-chemotherapy retroperitoneal lymph node dissection and resection of chest tumor under the same anesthetic is appropriate based on morbidity and tumor pathology

PURPOSE

We determine if post-chemotherapy resection of residual retroperitoneal and chest tumor under the same anesthetic is reasonable based on tumor pathology and morbidity, and if the finding of necrosis in the abdomen allows observation of chest tumor.

MATERIALS AND METHODS

We retrospectively reviewed 143 post-chemotherapy patients who underwent resection of residual retroperitoneal and chest disease under the same anesthetic.

RESULTS

Retroperitoneal pathology was generally predictive of chest pathology. Concordance existed in 77.5% of patients with necrosis, 70% with teratoma and 69% with cancer of the abdomen. However, the correlation was much stronger (86%) in predicting necrosis/fibrosis if cases were categorized as uncomplicated by Indiana University criteria. Although the morbidity of the combined approach is higher than that of standard post-chemotherapy retroperitoneal lymph node dissection, it was acceptable.

CONCLUSIONS

The morbidity of post-chemotherapy retroperitoneal lymph node dissection and resection of chest disease under the same anesthetic is acceptable. Retroperitoneal pathology generally predicts chest pathology but this correlation is much stronger if the case is uncomplicated based on our criteria. In an uncomplicated case the discovery of necrosis of the abdomen allows observation of chest tumor.

En bloc nephrectomy in patients undergoing post-chemotherapy retroperitoneal lymph node dissection for nonseminomatous testis cancer: indications, implications and outcomes

PURPOSE

We review the indications for nephrectomy at post-chemotherapy retroperitoneal lymph node dissection, identify patients at risk for nephrectomy and assess the impact of nephrectomy on outcome.

MATERIALS AND METHODS

Using a computerized data base and chart review we retrospectively reviewed the records of 848 patients who underwent retroperitoneal lymph node dissection after chemotherapy.

RESULTS

En bloc nephrectomy was performed at retroperitoneal lymph node dissection after chemotherapy in 162 of the 848 patients (19%). The indications for nephrectomy included contiguous involvement of perirenal structures in 73% of the cases, renal vein thrombosis in 6%, a poorly functioning or nonfunctioning renal unit in 5% and a combination of these conditions in 16%. Pathological studies of the hilum revealed cancer in 20% of the cases, teratoma in 49% and fibrosis in 31%. Patients requiring nephrectomy had significantly more advanced disease and larger disease volume at presentation and after chemotherapy. There were no significant differences in perioperative morbidity or mortality compared with patients who did not undergo nephrectomy. Only 3 patients required perioperative dialysis and none required long-term renal support.

CONCLUSIONS

These findings support en bloc nephrectomy at post-chemotherapy retroperitoneal lymph node dissection in select patients with large volume perihilar retroperitoneal disease.

[The Indiana pouch continent cutaneous urinary diversion]

Initially, the procedure was simply an ileo-caecal segment, as it was thought that peristalsis of the terminal ileum and the ileo-caecal valve accounted for continence. The Rowland group made some modifications, using 8-10 cm of terminal ileum and 30 cm of caecum and ascending ileum. By constructing an efferent limb using staples, a highly reliable continence mechanism is created. The absorbable staples reduce the operating time by about 1 hour and make the been operated on using these staples, and no problems with stones or infections have been encountered, with only 2 patients reporting fragments of staples in their urine.

[The Indian pouch as an orthotopic reservoir]

Patients undergoing this procedure should be strongly motivated and should have normal or near-normal bowel function. A reservoir is made using an 18-20 cm segment of terminal ileum, caecum and ascending colon. The ureters are implanted along the taenia of the ascending colon. The result is a neo-bladder that is close to the ideal ellipsoid shape. The stapling technique used decreases operating time and the detubularisation maintains low pressure in the neo-bladder. Although the operation has so far been performed on only 10 patients results have been very favourable and it has proved to be a useful alternative form of diversion.

Postchemotherapy retroperitoneal lymph node dissection is effective therapy in selected patients with elevated tumor markers after primary chemotherapy alone

OBJECTIVES

Elevated tumor markers after primary chemotherapy for metastatic testis cancer are usually an indication of persistent cancer. Subsequent treatment has usually been salvage chemotherapy. This article examines the possibility that selected patients can achieve long-term disease-free survival with surgery alone.

METHODS

Using a computerized data base of 627 postinduction chemotherapy retroperitoneal lymph node dissections (PC-RPLND), 23 patients with elevated tumor markers who have undergone PC-RPLND after induction chemotherapy alone were identified. Of the 23 patients, 15 were considered candidates for salvage chemotherapy, but instead underwent salvage surgery. Case histories were reviewed to establish selection criteria for PC-RPLND.

RESULTS

Eight patients originally presented as clinical Stage C, 6 as clinical Stage B-3, and 1 as clinical Stage B-2. All patients initially received cisplatin combination chemotherapy. Twelve patients had an elevated alpha-fetoprotein level and 3 patients had an elevated beta human chorionic gonadotropin level prior to PC-RPLND. Seven patients had rising markers at the time of PC-RPLND. Seven patients had teratoma only in their resected specimen and all have no evidence of disease (NED) at a median of 35 months. Two patients had necrosis only in their RPLND specimen and both are NED at 10 and 42 months. Six patients had cancer in their resected specimen and 2 are NED, 1 is alive with disease, and 3 are dead of disease. Five of the 6 patients with cancer in their resected specimen were the only patients who received postoperative chemotherapy.

CONCLUSIONS

Some patients with modest elevations of tumor markers after induction chemotherapy may only have teratoma or necrosis in the postchemotherapy resected specimen. These patients (n = 9) remain continuously NED. Patients who undergo salvage surgery and have cancer in the resected specimen do less well, but selected patients can be cured with this modality and thus avoid the morbidity of salvage chemotherapy.

Continent cutaneous urinary diversion

Using the case history of a 57-year-old woman with a G3 T1 bladder cancer as a reference point, general considerations on tumor biology and therapeutic choices are reviewed. Options for urinary tract diversion or reconstruction are presented. This author recommends radial cystectomy for this patient with continent cutaneous urinary diversion, the Indiana pouch. Important technical points of the surgical procedure are emphasized.

Nerve sparing post-chemotherapy retroperitoneal lymph node dissection for advanced testicular cancer

PURPOSE

Nerve sparing techniques are used routinely during retroperitoneal lymph node dissection in patients with low stage testis cancer in an attempt to preserve postoperative ejaculation. Preservation of ejaculation without an increased retroperitoneal recurrence rate in such patients prompted us to reevaluate the role of nerve sparing techniques in select patients undergoing post-chemotherapy retroperitoneal lymph node dissection.

MATERIALS AND METHODS

Of 472 patients who underwent post-chemotherapy retroperitoneal lymph node dissection between March 1988 and January 1995, 93 (19.7%) underwent a nerve sparing procedure. Two patients died of disseminated cancer within 6 months after post-chemotherapy retroperitoneal lymph node dissection. In 10 patients the ejaculatory status could not be established from the clinical notes and the patient was lost to followup. The remaining 81 patients form the basis of this report. Disease status, complications and ejaculatory status were evaluated. Mean followup was 35.5 months.

RESULTS

Of the patients 76.5% reported normal ejaculation after post-chemotherapy retroperitoneal lymph node dissection. Testis cancer recurred after nerve sparing surgery in 6 patients but no tumor was retroperitoneal. Ten pregnancies have been reported to date with uneventful term deliveries in 7.

CONCLUSIONS

Select patients are candidates for nerve sparing post-chemotherapy retroperitoneal lymph node dissection. Although indications for nerve sparing techniques in the post-chemotherapy population have expanded, the local recurrence rate has not increased. Nerve sparing post-chemotherapy retroperitoneal lymph node dissection can preserve the inherent fertility potential of the patient without increasing retroperitoneal relapse rates.

Role of Retroperitoneal Lymph Node Dissection in the Management of Testicular Cancer

BACKGROUND: Retroperitoneal lymph node dissection is an important component of staging and management of nonseminomatous germ-cell carcinoma of the testis. Ejaculatory impotence has been a dominant aspect of operative morbidity. METHODS: The author has led the investigation of a series of modifications of operative techniques with the aim of reducing morbidity while retaining the prognostic and therapeutic benefits for retroperitoneal lymph node dissection. RESULTS: The advances in surgical techniques have reduced the incidence of ejaculatory impotence to less then 5%. Guidelines for the type of retroperitoneal lymph node dissection for different clinical stages of disease are presented. CONCLUSIONS: The advances in surgical techniques for retroperitoneal node dissection have minimized morbidity. The procedure plays a role in many clinical stages of testicular cancer.

Post-chemotherapy resection of nonseminomatous germ cell testicular tumors metastatic to the mediastinum

PURPOSE

We determined if the behavior of germ cell tumors metastatic to the mediastinum is different from that of primary mediastinal germ cell tumors, a group known to have distinct clinical features.

MATERIALS AND METHODS

A search of the computerized data base for germ cell tumors metastatic to the mediastinum at our university revealed 80 patients, 65 of whom underwent concomitant retroperitoneal lymph node dissection at mediastinal surgery.

RESULTS

Of the patients 60 (75%) are free of disease, 14 (18%) died of cancer and 6 (8%) are living with disease. Mediastinal pathology included teratoma in 65% of the patients, cancer in 26% and fibrosis in 9%. Of the 65 patients who underwent retroperitoneal lymph node dissection 75% had teratoma, 15% had fibrosis and 10% had cancer. Mediastinal relapses after dissection were rare (4 of 80 patients).

CONCLUSIONS

Germ cell tumors metastatic to the mediastinum appear to behave similarly to those metastatic to the retroperitoneum. Primary mediastinal germ cell tumors have an entirely different clinical course. Teratoma is the predominant pathological type of post-chemotherapy germ cell cancer metastatic to the mediastinum.

The impact of pre-donated autologous blood and intra-operative isovolaemic haemodilution on the outcome of transfusion in patients undergoing radical retropubic prostatectomy

OBJECTIVE

To assess the impact of pre-donated autologous blood and intra-operative isovolaemic haemodilution on the outcome of transfusions in patients undergoing radical retropubic prostatectomy.

PATIENTS AND METHODS

The charts and transfusion records of 192 consecutive patients undergoing radical retropubic prostatectomy were reviewed retrospectively.

RESULTS

Of 192 patients, 14% required homologous transfusions, the rate of which varied significantly depending upon blood availability (autologous, haemodilution or homologous) (P < 0.001): 66% of patients with only autologous blood available were transfused a mean of 1.96 units (range 1-6) of blood, of which 87% received autologous alone. 12% both autologous and homologous and 1% homologous blood only. Of the pre-donated autologous units, 44% were wasted.

CONCLUSIONS

Both the pre-donation of autologous blood and intra-operative isovolaemic haemodilution lower the risk of homologous blood transfusion. It is recommended that patients pre-donate 2 units of autologous blood and undergo intra-operative isovolaemic haemodilution before radical prostatectomy.

Malignant testicular neoplasms in immunosuppressed patients

PURPOSE

Testicular cancers were studied in patients on immunosuppression.

MATERIALS AND METHODS

A retrospective analysis was done of testicular cancer in patients on immunosuppression reported on between 1975 and 1995.

RESULTS

The management schemes adopted in the immunosuppressed population followed the generally accepted management concepts. No patient with low stage (A to B1) disease died of testis cancer. Only 4 of 66 patients (6.1%) with the acquired immunodeficiency syndrome died of testis cancer compared to 5 of 20 (25%) after transplantation, implying significantly higher cause specific mortality in post-transplant patients (Fisher's exact test, p < 0.01). The incidence of adverse effect of therapy did not differ from the expected incidence in other patients.

CONCLUSIONS

Patients on immunosuppression with testicular neoplasms should be treated in the standard fashion as indicated by tumor histology and stage of disease, since most will tolerate therapy and benefit from the standard treatment protocols.

Present experience with the Indiana pouch

The Indiana pouch was developed as a modification of the Glichrist procedure in 1984. The need for full detubularization of the reservoir was recognized early and was achieved by an ileal patch on the cecal reservoir or by an antimesenteric incision of the cecal segment with folding and transverse closure, the efferent limb and continence mechanism were modified to promote ease of catheterization and improved continence. These modifications gave markedly better results with lower reoperation rates. A group of 81 patients with a minimum of 2 years of follow-up are reported herein. The most recent modification uses absorbable GIA and TA55 staples to detubularize and close the reservoir. This stapling technique has been employed in 20 patients and has resulted in decreased operating times without any significant increase in complications. In its current form, the Indiana pouch meets all the criteria for a satisfactory continent cutaneous reservoir and has a favorable reoperation rate as compared with other pouches.

Delayed orchiectomy after chemotherapy for metastatic nonseminomatous germ cell tumors

PURPOSE

We reviewed current experience at our university with delayed orchiectomy after chemotherapy in patients with metastatic nonseminomatous germ cell tumors.

MATERIALS AND METHODS

We retrospectively analyzed the records of 160 patients with metastatic germ cell cancer who were given systemic chemotherapy, and subsequently underwent orchiectomy and retroperitoneal lymph node dissection.

RESULTS

Analysis of 160 testicular specimens revealed necrosis or scar in 70 (43.7%), pure teratoma in 50 (31.2%) and persistent germ cell cancer in 40 (25%). Corresponding incidences of histopathological findings in the post-chemotherapy retroperitoneal lymph node dissection specimens were significantly different, correlating with less than half of the cases (chi-square, p = 0.002).

CONCLUSIONS

Our study confirms the need for delayed orchiectomy after systemic chemotherapy even when there seems to be a partial or complete clinical response at other sites.

Hyperamylasemia after post-chemotherapy retroperitoneal lymph node dissection for testis cancer

PURPOSE

Postoperative hyperamylasemia was evaluated in patients undergoing post-chemotherapy retroperitoneal lymph node dissection for testis cancer.

MATERIALS AND METHODS

Serum levels of amylase, lipase and bilirubin were evaluated prospectively in the immediate postoperative period in 39 consecutive patients who underwent post-chemotherapy retroperitoneal lymph node dissection.

RESULTS

Hyperamylasemia was found in 16 patients (41%), hyperlipasemia in 17 (43%) and hyperbilirubinemia in 9 (23%). Peak elevations were observed at 24 hours postoperatively and most returned to normal at 1 week. Elevation of these parameters was significantly associated with length and difficulty of the procedure. No patient demonstrated clinical acute pancreatitis.

CONCLUSIONS

Extended retraction of the pancreas during post-chemotherapy retroperitoneal lymph node dissection may cause a minor reversible injury to the pancreas expressed as hyperamylasemia, hyperlipasemia and, rarely, jaundice. These findings are important to consider in the differential diagnosis of hyperamylasemia following post-chemotherapy retroperitoneal lymph node dissection.

Clinical stage B non-seminomatous germ cell testis cancer: the Indiana University experience (1965-1989) using routine primary retroperitoneal lymph node dissection

Between 1965 and 1989, 1180 patients at Indiana University, U.S.A., underwent retroperitoneal lymph node dissection (RPLND) for non-seminomatous germ cell (NSGC) testis cancer of whom 638 cases had primary RPLND. A subset of 174 cases were considered clinical stage B (or II) before surgery (retroperitoneal nodal metastases by clinical staging). Surgery revealed that 23% (n = 41) had pathological stage A disease (no cancerous nodes). This error rate in clinical staging has decreased somewhat with improved techniques, but remains approximately 20% over the last decade. The relapse rate in pathological stage A (n = 41) was 5% (n = 2), both of whom were cured by chemotherapy. The relapse rate in pathological stage B without postoperative adjuvant treatment (n = 54) was 35% (n = 19); 2 patients died. This indicates that 65% of pathological stage B cases were cured by RPLND alone. From 1979 to 1989, the 140 pathological stage B cases participated in a randomised prospective trial of post-RPLND adjuvant chemotherapy versus no postoperative treatment. Forty two per cent (n = 59) received postoperative platinum-based therapy (two cycles), and there has been no relapse after RPLND for stage B disease. While advances in chemotherapy for NSGC testis cancer have led to its application by several study groups to clinical stage B (or II) testis cancer (with surgery reserved only for those in partial remission), the equivalent cure rate with RPLND surgery with chemotherapy rescue reserved for those who relapse appears to have both cost and risk-benefit advantages.

Incidental appendectomy during urological surgery

PURPOSE

To investigate the issue of incidental appendectomy during urological surgery we retrospectively studied its consequences in 2 groups of urological patients.

MATERIALS AND METHODS

We studied 147 patients undergoing cystectomy and urinary diversion (group 1) and 200 undergoing primary retroperitoneal lymphadenectomy (group 2). Incidental appendectomy was performed in 122 (83%) and 114 (57%) patients, respectively.

RESULTS

The incidence of infectious complications in group 2 was significantly higher among patients who underwent incidental appendectomy compared to those without appendectomy (9.6% and 2.3%, respectively, p = 0.032). No difference was noted among the patients in group 1 (10.6% and 12.0%, respectively, p = 0.51).

CONCLUSIONS

When evaluating the prophylactic merits, incidental appendectomy can be performed safely during radical cystectomy and urinary diversion. It is probably contraindicated in patients undergoing retroperitoneal lymphadenectomy for testis cancer due to the apparent added risk of infectious complications.

Cystography after radical retropubic prostatectomy: clinical implications of abnormal findings

OBJECTIVES

In many institutions, cystography is obtained routinely after radical retropubic prostatectomy to assess the integrity of the vesicourethral anastomosis before the removal of the catheter. This study presents the Indiana experience with cystograms performed following radical retropubic prostatectomy.

METHODS

The experience with 260 cystograms performed in 245 consecutive patients following radical retropubic prostatectomy was reviewed retrospectively, with a special reference to the clinical implications of abnormal findings.

RESULTS

After a standard catheterization period of 14 to 21 days (mean, 19.2), 94.3% of the catheters were removed safely without adverse clinical consequences. The presence of a minimal contained contrast extravasation did not affect outcome after the removal of the catheter. The overall incidence of clinically significant extravasation was found to be 5.7% and was further reduced to 2.4% if extravasation was not suggested clinically in the postoperative course.

CONCLUSIONS

Based on the current literature, significant extravasation is a common finding during the first 5 to 8 postoperative days. Therefore, management strategies advocating early urethral catheter removal should include routine cystographic studies. Otherwise, cystographic confirmation of anastomotic integrity before the removal of the catheter following 14 to 21 days of catheterization is not indicated in the routine postradical prostatectomy patient.

Color Doppler flow imaging for deep venous thrombosis screening in patients undergoing pelvic lymphadenectomy and radical retropubic prostatectomy for prostatic carcinoma

Patients undergoing pelvic lymphadenectomy and radical retropubic prostatectomy are traditionally considered to be at high risk for postoperative venous thromboembolic complications. A prospective deep venous thrombosis screening regimen was initiated at our medical center in 1990 following 2 cases of fatal pulmonary embolism that occurred after hospital discharge. During a 3-year period 245 consecutive patients undergoing radical retropubic prostatectomy for prostate cancer were screened postoperatively for lower extremity deep venous thrombosis using ultrasound duplex scanning with color Doppler flow imaging. The results were correlated only with the development of clinical deep venous thrombosis. No additional diagnostic modalities were used to confirm a normal venous system in asymptomatic patients. Venous thromboembolic complications were encountered in 9 of the 245 patients (3.6%). In 2 patients deep venous thrombosis was associated with nonfatal pulmonary embolism. Only 2 of the 9 cases of deep venous thrombosis were detected by color Doppler flow imaging screening. The striking decrease in the incidence of deep venous thrombosis following radical prostatectomy in the last decade and the low yield of screening at a single point in time may warrant reconsideration of the need for deep venous thrombosis screening among patients undergoing pelvic lymphadenectomy and radical retropubic prostatectomy for prostate cancer.

Complications of post-chemotherapy retroperitoneal lymph node dissection

The surgical morbidity rate of 603 patients who underwent lymphadenectomy after primary chemotherapy for clinical stages II and III testis cancer from 1982 to 1992 was reviewed. There were 144 complications in 125 patients (20.7%). The majority of patients (93%) had a tumor volume of greater than 5 cm. Five patients died 3 to 47 days postoperatively, for an operative mortality rate of 0.8%. Pulmonary complications were the most frequent cause of severe morbidity: 6 patients had the adult respiratory distress syndrome and 5 needed prolonged ventilation. The underlying cause was a combination of bleomycin induced pulmonary toxicity, and large volume retroperitoneal and pulmonary disease resected in these patients. Limiting inspired oxygen concentration and perioperative volume replacement are imperative to minimize bleomycin related pulmonary morbidity. Additional procedures, such as nephrectomy and colectomy, did not add to the morbidity rate. Among patients undergoing concomitant venacavectomy there was a higher occurrence of postoperative chylous ascites. Most of the other complications (gastrointestinal, lymphatic, neurological and renal) were temporary and treated conservatively. Perioperative management of the post-chemotherapy testis cancer patient is different from that of the patient undergoing primary retroperitoneal lymphadenectomy. The latter operation is usually performed in physically fit patients and the surgical template of dissection is of a smaller scale. Thus, the complications in this group are minor and without mortality. Specific technical considerations and difficulties are common to post-chemotherapy patients. Factors, such as large volume of disease, post-chemotherapy desmoplastic reaction and extensive retroperitoneal dissection, make these patients more prone to have complications. Decreased pulmonary, renal and nutritional reserves add to the surgical morbidity. Knowledge of possible pitfalls and their causes can avoid unnecessary operative complications.

The role of retroperitoneal lymphadenectomy in clinical stage B testis cancer: the Indiana University experience (1965 to 1989)

Between 1965 and 1989, 1,180 patients underwent retroperitoneal lymph node dissection for nonseminomatous germ cell testis cancer (638 underwent primary dissection). Of these patients, 174 were considered to have clinical stage B disease preoperatively (suspected retroperitoneal node metastases by clinical staging). Surgery revealed that 41 patients (23%) actually had pathological stage A disease (no cancerous nodes). This nonspecificity in clinical staging remains consistent despite advance in clinical staging methods during this 25-year period. Of the pathological stage B cancer patients 65% were cured by retroperitoneal lymph node dissection alone. These long-term data indicate that primary retroperitoneal lymph node dissection for low stage metastatic nonseminomatous germ cell testis cancer (pathological stage B) not only had diagnostic but also therapeutic impact. Furthermore, this cure rate with long-term followup is equivalent to that of current series of primary chemotherapy alone for stage B disease, which are still relatively early reports. This cure rate with single modality therapy (retroperitoneal lymph node dissection alone) was accomplished within an average of 4 hours and, therefore, should be more time and cost-effective than prior reports of 3 and 4 courses of primary chemotherapy. In the post-cisplatin era (1979 to 1989), 140 patients with clinical stage B disease were treated with primary retroperitoneal lymph node dissection: 32 (23%) had pathological stage A cancer and 2 of them (6%) had relapse. Both patients are currently disease-free with subsequent chemotherapy. Of the remaining 108 patients with pathological stage B disease 49 received no adjuvant chemotherapy and 59 received cisplatin-based adjuvant chemotherapy. Among the former 49 patients 18 (37%) had relapse and 2 died. No patient receiving postoperative cisplatin-based adjuvant chemotherapy had relapse. The overall survival rate in these 140 clinical stage B cancer patients was 98%. There were 3 deaths, only 1 from cancer. The addition of cisplatin-based adjuvant chemotherapy postoperatively has rendered pathological stage B nonseminomatous germ cell testis cancer entirely free of subsequent relapse. Therefore, retroperitoneal lymph node dissection as monotherapy is curative in two-thirds of the patients with stage II disease, while the remaining one-third with progression to clinical relapse can be reliably saved by chemotherapy. Future considerations in selecting therapy for clinical stage II nonseminomatous germ cell testis cancer will be risk-benefit, cost-benefit and quality of life issues. Several cooperative studies will examine these issues, involving European and United States groups.

Evolution of the Indiana continent urinary reservoir

The Indiana continent urinary diversion evolved from the Gilchrist procedure. Full detubularization of the reservoir segment, tapering of the efferent limb with staples, plication of the ileocecal valve, and tunneled tenial implants have resulted in a reliable and reproducible continent cutaneous urinary reservoir. In this report the first 69 patients treated with these techniques are reviewed after a minimum 2-year followup. Overall day and night continence rates were 97% by 1 year after surgery. More than 80% of all patients are able to sleep a normal nighttime interval without catheterizing or leaking. Early plus late reoperation rates for problems related to the pouch were 17%. This rate compares favorably to other series of continent cutaneous reservoirs and even to series of ileal conduits.

The fertility of patients with clinical stage I testis cancer managed by nerve sparing retroperitoneal lymph node dissection

Nerve sparing retroperitoneal lymph node dissection reliably preserves emission and ejaculation in patients with clinical stage I nonseminoma. The fertility of 51 patients who underwent nerve sparing retroperitoneal lymph node dissection was assessed by 3 different methods: standard semen analysis, analysis of chromatin content by deoxyribonucleic acid histogram and assessment of ultimate fertility status by a questionnaire. Approximately 75% of these patients have semen analyses generally considered to be in the normal range. Virtually all patients who underwent deoxyribonucleic acid histogram analysis had histograms similar to controls. A retrospective analysis of fertility was performed in 201 patients who had previously undergone nerve sparing retroperitoneal lymph node dissection. Of these patients who attempted pregnancy after nerve sparing retroperitoneal lymph node dissection 76% have been successful. Approximately 75% of patients who present with clinical stage I nonseminoma are potentially fertile. Nerve sparing retroperitoneal lymph node dissection is capable of preserving this potential in allowing these patients to father children.

Complications of primary retroperitoneal lymph node dissection

The surgical morbidity in 478 patients who underwent primary retroperitoneal lymphadenectomy for clinical stages I and II nonseminomatous testicular cancer from 1982 to 1992 was reviewed. There were 54 complications in 51 patients (10.6%) and no operative related mortality. Superficial wound infection was the most frequent complication, comprising 45% of the total number of complications. Most major complications were related to small bowel obstruction and atelectasis. No complications caused permanent disability. The complication rate was less in patients who underwent a modified unilateral procedure (9.4%) than in those who underwent bilateral dissection (19.3%). Complications were significantly less with procedures done during the latter 6 years of the study (1987 to 1992). The ejaculation rate of patients undergoing a nerve sparing procedure was 98%, which reflects the increase in experience gained with the technique of nerve sparing modified unilateral dissection for early stage testicular cancer. This study reinforces the view that primary retroperitoneal lymph node dissection is an operation with minimal morbidity and no long-term effects. Furthermore, this study serves as the basis for cost-benefit and risk-benefit analyses of primary retroperitoneal lymph node dissection in low stage testicular cancer, which can be set against surveillance and primary chemotherapy programs.

Stage I nonseminomatous germ-cell testicular cancer--management options and risk-benefit considerations

The results obtained with primary retroperitoneal lymph-node dissection (RPLND) in 464 patients with clinical stage A nonseminomatous germ-cell (NSGC) testicular cancer over a period of 25 years (1965-1989) were reviewed. Results were analyzed in clinical terms and subdivided into early (1965-1978) and contemporary (1979-1989) findings so as to be comparable with series using radiotherapy or surveillance. Between 1965 and 1978 (86 clinical stage A patients), the overall relapse rate of 15% (n = 13) was similar to that obtained in radiotherapy series but the survival (98.8% after RPLND) was superior to that achieved with irradiation (87%). From 1979 to 1989, 378 clinical stage A cases had primary RPLND, of whom 29% (n = 111) had cancerous nodes. The relapse rate for pathological stage A patients (n = 267) was 11% and two patients died. The rate of relapse for pathological stage B patients who did not receive adjuvant chemotherapy was 32%. No relapse was seen among 46 pathological stage B patients given postoperative adjuvant chemotherapy. The mortality of 0.7% observed among 378 clinical stage A RPLND cases was lower than the 2% value reported in surveillance series. Although not statistically significant, these consistent results reported for two eras (pre- and postplatinum) spanning a period of 25 years suggest a sound basis for the surgical approach. The anatomic and medical principles in oncology, which have supported this approach, remain cogent today. They are discussed herein. Now that nerve-sparing techniques have been developed, the one long-term morbidity of RPLND (i.e., anejaculation) can be avoided.(ABSTRACT TRUNCATED AT 250 WORDS)

Nerve sparing retroperitoneal lymphadenectomy after primary chemotherapy for metastatic testicular carcinoma

Initial success with nerve sparing retroperitoneal lymph node dissections in patients with low stage nonseminomatous germ cell tumors of the testis has led to the application of these techniques to a select group of 40 patients treated after chemotherapy at our institution between March 1988 and November 1991. A minimum 1-year followup was available for 38 patients. There have been no abdominal relapses, and 34 of the 38 patients report normal ejaculation postoperatively. Nerve sparing techniques are applicable to select patients undergoing retroperitoneal lymph node dissection after primary chemotherapy for metastatic disease without increasing the chance of local recurrence. Emission and ejaculation are preserved in the majority of patients.

Complications of primary retroperitoneal lymph-node dissection for low-stage testicular cancer

The surgical complications encountered in 478 patients who underwent primary retroperitoneal lymph-node dissection for clinical stage A and B nonseminomatous testicular cancer during the period ranging from 1982 to 1992 were reviewed. There were 54 complications in 51 patients (10.6%), and there was no surgery-related mortality. There were 16 minor complications and 38 major complications. The most frequent complication encountered was superficial wound infection, and many of the major complications were related to small-bowel obstruction and atelectasis. The incidence of complications was significantly lower in patients operated on during the last 6 years of the study (1987-1992). The complication rate was lower in patients who underwent modified unilateral procedures than in those who had bilateral dissections. The ejaculation rate of patients undergoing nerve-sparing procedures was 98%. This study reinforces the conclusion that primary retroperitoneal lymph-node dissection is an operation yielding minimal morbidity and no long-standing effect.

Fertility considerations in nerve-sparing retroperitoneal lymph-node dissection

Nerve-sparing retroperitoneal lymph-node dissection (RPLND) maintains the patient's ability to ejaculate postoperatively. However, since testicular cancer patients sometimes have diminished spermatogenesis, questions have been raised as to the advisability of nerve preservation relative to ultimate fertility. Fertility status was assessed in clinical stage A patients by two methods. These included standard semen analysis and a post-RPLND survey. The results show that approximately 75% of non-seminomatous testicular cancer patients who present in clinical stage A have fertility potential as based on semen analysis. Additionally, of those patients responding to the post-RPLND survey who had attempted pregnancy following RPLND, 76% reported attainment of pregnancy. Nerve-sparing RPLND maintains fertility potential in clinical stage I patients; furthermore, this fertility potential appears to be worth preserving as many patients will be capable of impregnating their partners.

Stage II nonseminomatous germ-cell testicular tumors--the Indiana experience and risk-benefit analysis

Controversy exists in the appropriate management of patients with nonseminomatous testicular cancer presenting as clinical stage B disease. Traditional treatment in the United States has included retroperitoneal lymph-node dissection (RPLND). Conversely, in Europe and other places some of these patients have been managed with primary chemotherapy. The experience with RPLND in clinical stage B disease at Indiana University from 1965 to 1989 was reviewed. A total of 174 patients were considered to be in clinical stage B prior to RPLND. After RPLND, 23% of these patients (n = 41) were found to have pathological stage A disease. In all, 77% (n = 133) were determined to be in pathological stage B. Of those pathological stage B patients who did not receive adjuvant chemotherapy, 65% were cured by RPLND alone. The pathological stage B patients who went on the receive postoperative adjuvant chemotherapy displayed an overall 14% chance of relapse. (Patients treated early in the series did not receive cisplatin-based chemotherapy.) The overall survival over the entire period was 96%. In the more modern era, during which cisplatin-based chemotherapy was available, the overall survival was 98%. RPLND is an effective procedure for the management of clinical stage B nonseminomatous testicular cancer. It provides excellent survival in patients found to have pathological stage B disease; additionally, it avoids the unnecessary toxicity of chemotherapy in the 23% of patients who in fact are in pathological stage A.

Management of chylous ascites after retroperitoneal lymph node dissection for testicular cancer

Iatrogenic ascites is an uncommon complication of surgery of the retroperitoneum, the base of the mesentery or mediastinum. We treated 18 patients with chylous ascites occurring after retroperitoneal dissection for testicular cancer. Patients were diagnosed by paracentesis or on clinical grounds (increasing abdominal girth). Of interest, 6 patients underwent resection of the inferior vena cava as part of the procedure, and this appears to be a high risk group for this complication. Management options include dietary restriction of fat, administration of medium chain triglycerides and diuretics, hyperalimentation, peritoneovenous shunt or surgery. The majority of patients were managed successfully by dietary treatment.

Primary retroperitoneal lymph node dissection in clinical stage A non-seminomatous germ cell testis cancer. Review of the Indiana University experience 1965-1989

The results of primary retroperitoneal lymph node dissection (RPLND) in 464 patients with clinical stage A non-seminomatous germ cell (NSGC) testis cancer treated over 25 years (1965-1989) were reviewed. The results were analysed in clinical terms and subdivided into early (1965-1978) and contemporary (1979-1989) groups in order to be comparable with series using radiotherapy or surveillance. Between 1965 and 1978 (86 clinical stage A patients) the overall relapse rate of 15% (n = 13) was similar to that of radiotherapy series but survival (97.7% after RPLND) was superior to that achieved with irradiation (87%). From 1979 to 1989, 378 clinical stage A patients had primary RPLND and 30% of them (n = 112) had cancerous nodes. The relapse rate for pathological stage A (n = 266) was 12% and 2 patients died. The relapse rate in pathological stage B patients without adjuvant chemotherapy was 34%. No relapse was seen among 48 pathological stage B patients who received post-operative adjuvant chemotherapy. The death rate was 0.8% among 378 clinical stage A RPLND patients. While not statistically significantly different from death rates reported in current surveillance series, these consistent results spanning 2 eras (before and after cisplatin) over 25 years suggest a sound basis for the surgical approach. The anatomical and medical principles in oncology, which have supported this approach, still remain cogent today. Now that nerve-sparing techniques have been developed, the only long-term morbidity of RPLND (anejaculation) has been avoided. It would seem appropriate to include nerve-sparing RPLND techniques in the management of clinical stage A disease.

Retroperitoneal lymphadenectomy for clinical stage A testis cancer (1965 to 1989): modifications of technique and impact on ejaculation

Results with primary retroperitoneal lymphadenectomy in 464 patients with clinical stage A nonseminomatous germ cell testis cancer (1965 to 1989) were reviewed. The false-negative staging error by clinical methods remains at 30%. The relapse rate in pathological stage A cancer patients was 11% (37 of 323), with 2 deaths. For pathological stage B disease 64% of the patients were cured by retroperitoneal lymphadenectomy alone. With modern adjuvant chemotherapy no stage B tumor relapsed since 1979 and the survival rate was 100%. For all 25 years (464 patients) the relapse rate was 14% and the survival rate was 98.9% (3 cancer and 2 noncancer deaths). Because these results are based on preoperative clinical staging, they are directly comparable with series using radiotherapy or surveillance.

Prognosis and other clinical correlates of pathologic review in stage I and II testicular carcinoma: a report from the Testicular Cancer Intergroup Study

PURPOSE

The Testicular Cancer Intergroup Study (TCIS) was undertaken to evaluate the pathologic findings in early-stage testicular cancer as determined by central pathology review, to compare these findings with the interpretation by the contributing pathologists, and to make correlations with various clinical parameters and outcomes.

PATIENTS AND METHODS

The prospective study of non-seminomatous germ cell testicular cancer staged surgically involved 459 eligible patients with stage I (node-negative) or stage II (node-positive) disease. Pathologic materials from both the orchiectomy and lymphadenectomy specimens were submitted to a central laboratory for evaluation.

RESULTS

Central and local pathologists differed significantly in their identification of certain cellular histologies (primarily yolk sac tumors [YST]) and recognition of invasion into vascular structures. In contrast to our prior findings with local pathologic assessment, venous/lymphatic invasion as determined by central review predicted relapse in both stages. In pathologic stage I disease, the relapse rate was 19.4% (12 of 62 cases) for those with invasion versus 6.0% (10 of 168 cases) for those without invasion. In pathologic stage II disease, the respective relapse rates were 63.5% (40 of 63 cases) and 24.0% (six of 25 cases). Vascular invasion was jointly predictive with nodal stage for risk of relapse. The percentage of embryonal carcinoma (EC) in the primary tumor was predictive of nodal stage and relapse in a univariate, but not a multivariate, analysis. In a large substudy, immunohistochemical staining identified a correlation between stain intensity in YST and serum alpha-fetoprotein (AFP) levels. In a similar fashion human chorionic gonadotropin (HCG) staining reactivity occurred exclusively in patients with syncytiotrophoblasts and correlated with serum levels of beta-HCG.

CONCLUSIONS

A number of tumor histology correlates with clinical parameters have been identified or confirmed. Careful pathologic scrutiny of the primary testicular tumor, especially for vascular invasion, provides important prognostic information.

Resection of the inferior vena cava or intraluminal vena caval tumor thrombectomy during retroperitoneal lymph node dissection for metastatic germ cell cancer: indications and results

A total of 42 patients underwent inferior vena caval resection (40) or intraluminal tumor thrombectomy (2) during retroperitoneal lymph node dissection for bulky abdominal metastatic nonseminomatous germ cell cancer (7% of all post-chemotherapy retroperitoneal lymph node dissection cases). The 3 indications for vena caval resection included tumor clearance (38%), vena caval scar occlusion (14%) and vena caval tumor thrombus (48%). En bloc vena caval resection to achieve tumor clearance was justified by subsequent nodal pathology (cancer in 63% of the specimens and teratoma in 31%). Vena caval resection in the presence of scar occlusion was de facto required by virtue of its incorporation in the specimen. Vena caval resection or thrombectomy is indicated for intraluminal tumor thrombus because thrombus pathology (cancer 35%, teratoma 45% and fibrosis 20%) reflected nodal pathology in 71% of the patients with cancer, 78% with teratoma and 100% with fibrosis. The complications of vena caval resection were generally transitory. The 71% survival rate justifies this intensive surgical approach because these patients had exhausted all chemotherapy options.

Nerve-sparing retroperitoneal lymphadenectomy with preservation of ejaculation

The feasibility of sparing postganglionic fibers of lumbar sympathetic nerves during the course of retroperitoneal lymphadenectomy has been investigated at our university medical center beginning in 1978. We selected 75 patients for nerve-sparing retroperitoneal lymphadenectomy in an effort to preserve ejaculatory function postoperatively. This cohort of patients was selected on the basis of clinical stage. Of the 75 patients 73 had clinical stage I disease. However, 14 of these 73 patients had pathological stage II cancer. No patient was treated with adjuvant chemotherapy after nerve-sparing retroperitoneal lymphadenectomy. Of these 14 patients with pathological stage II disease 4 had relapse: 1 with proved retroperitoneal recurrence, and 3 with serological elevations of tumor markers and questionable clinical findings as to anatomical site of relapse. All 4 patients are free of disease after chemotherapy and/or surgical (1) rescue. There were no local recurrences in the 61 patients with negative nodes. All 75 patients ejaculate and had no evidence of disease more than 2 years after nerve-sparing retroperitoneal lymphadenectomy. It is clear that nerve-sparing retroperitoneal lymphadenectomy is a feasible technique. As noted, it can even be applied to selected patients with low volume positive nodes, yet maintaining relapse and survival figures that are acceptable. Ejaculation is reliably preserved when this nerve-sparing technique is applied accurately in retroperitoneal lymphadenectomy.

Continent urinary reservoirs

Public awareness of the alternatives to wet stomas and the patient's concern for body image have significantly increased the demand for continent urinary reservoirs. In the final analysis, preservation of renal function is the standard for judging the success of a diversion, and long-term observations must be made with this point in mind. It seems likely that the continent reservoirs now available will preserve renal function.

Serum markers in testicular germ-cell neoplasms

At the present time, serum determinations of alpha fetoprotein and beta-HCG are the most useful markers in the management of germ-cell testis tumors. Serial determinations are vital to the monitoring of the response of the patient's tumor to therapy. Subsequent elevation of tumor markers is often the first evidence of recurrence of tumor and allows effective treatment to be instigated while the volume of recurrent tumor is extremely low. This markedly increases the likelihood of achieving complete remissions.

Testicular germ-cell neoplasms: curative approaches

Approximately 80 per cent of all patients with testis cancer will present with low-volume disease. If they are pathologic stage I, there is virtually a 100 per cent cure rate even though 5 to 10 per cent will relapse after node dissection. Those who have relapsed have been salvaged with systemic chemotherapy. If clinical stage I patients are followed on observation protocols, 20 to 30 per cent of the patients will relapse. Unfortunately, a small percentage of these patients will not be salvaged with chemotherapy because they have more advanced disease at the time that the relapse is discovered. The main objection to retroperitoneal lymph node dissection in patients with low-stage disease has been the issue of infertility induced by the procedure. This problem has been alleviated by the development of the prospective nerve-sparing procedures. Long-term follow-up is still required to make certain that the relapse rate is not significantly higher than with a full retroperitoneal lymph node dissection. Experience has demonstrated that patients with stage II disease will achieve a 98 to 99 per cent cure rate regardless of whether they have adjuvant chemotherapy after surgery, or full-course chemotherapy should they relapse (approximately 50 per cent). Advanced disease is best treated initially by systemic chemotherapy. The emphasis in the last few years has been on a reduction in the toxicity of chemotherapy while maintaining the high degree of efficacy. Surgery is used as an adjunct to chemotherapy in those patients who achieve a partial remission. Careful follow-up cannot be over emphasized in patients with any form of treatment for testis cancer. It is especially important that those patients who have teratoma present in the surgical specimens obtained at the time of a postchemotherapy lymph node dissection have prolonged follow-up, because recurrences have been noted as long as 6 to 8 years after the initial event. Although primary retroperitoneal or mediastinal germ-cell tumors do exist, the vast majority arise from the testis. If the diagnosis of germ-cell tumor has been made by some means other than orchiectomy, a careful review of the patient's history and physical findings is needed to guide the physician to the possible testicular site of origin. If no physical findings are present, scrotal ultrasound may be helpful in localizing a primary tumor of the testis. If such localization is possible, then a radical orchiectomy should be performed to prevent future seeding from persistent tumor in the testicle.(ABSTRACT TRUNCATED AT 400 WORDS)
