Development of Nomograms to Predict the Recovery of Erectile Function Following Radical Prostatectomy.

INTRODUCTION: Given the number of confounders in predicting erectile function recovery after radical prostatectomy (RP), a nomogram predicting the chance to be functional after RP would be useful to patients' and clinicians' discussions. AIM: To develop preoperative and postoperative nomograms to aid in the prediction of erectile function recovery after RP. MAIN OUTCOME MEASURES: International Index of Erectile Function (IIEF) erectile function domain score-based erectile function. METHODS: A prospective quality-of-life database was used to develop a series of nomograms using multivariable ordinal logistic regression models. Standard preoperative and postoperative factors were included. MAIN OUTCOME MEASURES: The nomograms predicted the probability of recovering functional erections (erectile function domain scores ≥24) and severe erectile dysfunction (≤10) 2 years after RP. RESULTS: 3 nomograms have been developed, including a preoperative, an early postoperative, and a 12-month postoperative version. The concordance indexes for all 3 exceeded 0.78, and the calibration was good. CLINICAL IMPLICATIONS: These nomograms may aid clinicians in discussing erectile function recovery with patients undergoing RP. STRENGTHS & LIMITATIONS: Strengths of this study included a large population, validated instrument, nerve-sparing grading, and nomograms that are well calibrated with excellent discrimination ability. Limitations include current absence of external validation and an overall low comorbidity index. CONCLUSIONS: It is hoped that these nomograms will allow for a more accurate discussion between patients and clinicians regarding erectile function recovery after RP.

Primary retroperitoneal lymph node dissection in low-stage testicular germ cell tumors: a detailed pathologic study with clinical outcome analysis with special emphasis on patients who did not receive adjuvant therapy.

OBJECTIVE: To evaluate, in detail, the histopathologic features of metastatic testicular germ cell tumors to retroperitoneal lymph nodes treated with primary retroperitoneal lymph node dissection (RPLND) and correlate the findings with patients' outcomes. MATERIALS AND METHODS: We studied 183 patients with documented pathologic stage II disease with or without elevated serum tumor markers, selected from 453 patients who underwent primary RPLND at our institution from 1989 to 2002. Tumor type(s), size and extent of disease, and amount of tumor necrosis were assessed and correlated with outcome. RESULTS: Embryonal carcinoma was the most common tumor type, present as the only component in 99 cases (54%) and the predominant tumor type (>50%) in 142 (78%). The number of positive lymph nodes ranged from 1 to 40 from a total of 2-80 lymph nodes examined (median, 28). Extranodal extension (ENE) was identified in 120 cases (66%). Among 73 patients followed up expectantly and with normal serum tumor markers, 19 experienced relapse, the probability of which was higher in patients with more positive nodes, larger metastases, and presence of ENE. However, none of these differences was statistically significant (all P >.2). The predominance of embryonal carcinoma and the presence of tumor necrosis were not significantly associated with outcome. CONCLUSION: In this cohort, most patients treated with primary RPLND and with positive lymph nodes also had ENE. We did not identify any variables to be significantly associated with relapse after RPLND in patients managed expectantly. Additional studies with more patients are needed to validate our findings.

Defining the impact of vascular risk factors on erectile function recovery after radical prostatectomy.

UNLABELLED: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Erectile function recovery after radical prostatectomy is affected by surgical technique and patient factors. Age and preoperative erectile function are the 2 patient factors that have been consistently shown to impact postoperative erectile function. The presence of vascular risk factors preoperatively seems to negatively impact erectile function recovery after radical prostatectomy independently from age, preoperative erectile function and surgical technique. OBJECTIVE: To examine whether vascular risk factors (VRFs) affect erectile function (EF) recovery after radical prostatectomy (RP). PATIENTS AND METHODS: From our prospective database we identified patients with clinically localised prostate cancer who had undergone RP and had preoperative information on EF and VRFs (hypertension, hypercholesterolaemia, diabetes mellitus, coronary artery disease [CAD], and cigarette smoking), surgeon-graded nerve-sparing status, and EF data collected between 24 and 30 months after RP. RESULTS: In all, 984 patients were included in the analyses. The frequency of the VRFs was as follows: hypertension (38%), hypercholesterolaemia (36%), diabetes mellitus (7%), CAD (5%), and cigarette smoking (37%). On univariate analysis, EF between 24 and 30 months was associated with age (r = 0.37, P < 0.001), EF before RP (r = 0.41, P < 0.001), NSS (r = 0.35, P < 0.001), and VRFs (0-2 vs >3 VRFs; r = 0.15, P = 0.003). On multivariable analysis all variables remained statistically significant, and accounted for 28% of the total variance in EF between 24 and 30 months after RP. CONCLUSIONS: The presence of VRFs seems to adversely affect EF recovery after RP independently of other factors. This observation might be useful for improving patient counselling before treatment and to support the development of new treatment strategies for erectile dysfunction after RP.

Evaluation of prediagnostic prostate-specific antigen dynamics as predictors of death from prostate cancer in patients treated conservatively.

Prostate-specific antigen (PSA) dynamics have been proposed to predict outcome in men with prostate cancer. We assessed the value of PSA velocity (PSAV) and PSA doubling time (PSADT) for predicting prostate cancer-specific mortality (PCSM) in men with clinically localized prostate cancer undergoing conservative management or early hormonal therapy. From 1990 to 1996, 2,333 patients were identified, of whom 594 had two or more PSA values before diagnosis. We examined 12 definitions for PSADT and 10 for PSAV. Because each definition required PSA measurements at particular intervals, the number of patients eligible for each definition varied from 40 to 594 and number of events from 10 to 119. Four PSAV definitions, but no PSADT, were significantly associated with PCSM after adjustment for PSA in multivariable Cox proportional hazards regression. All four could be calculated only for a proportion of events, and the enhancements in predictive accuracy associated with PSAV had very wide confidence intervals. There was no clear benefit of PSAV in men with low PSA and Gleason grade 6 or less. Although evidence that certain PSAV definitions help to predict PCSM in the cohort exist, the value of incorporating PSAV in predictive models to assist in determining eligibility for conservative management is, at best, uncertain.

Sexual bother following radical prostatectomyjsm.

INTRODUCTION: The literature on sexual bother in men with prostate cancer is conflicting. While some data indicate high bother from erectile dysfunction (ED) following prostate cancer treatments, other results suggest the life-saving nature of the treatment may mitigate ED concern. AIM: (i) To determine if sexual bother increases post radical prostatectomy (RP); (ii) To determine if men psychologically adjust to diminished erections; (iii) To identify baseline predictors of post-RP sexual bother. METHODS: We identified 183 men treated with RP who completed inventories including Erectile Function Domain (EFD) and Sexual Bother (SB) preoperatively and at 12 and 24 months postoperatively. Statistical analyses included repeated-measures analysis of variance and linear multiple regression. MAIN OUTCOME MEASURES: The EFD of the International Index of Erectile Function and the SB subscale from the Prostate-Health Related Quality-of-Life Questionnaire. RESULTS: The mean age of the sample was 58 +/- 7 years. The mean EFD scores decreased from baseline to the 24-month time point (24.8 vs. 16.7, P < 0.01). The mean SB scores increased from baseline to the 12 month time point (4.3 vs. 6.7, P < 0.01), and remained stable from the 12 month to 24 month time points (6.7 vs. 6.3, P = not significant [ns]). This was true for men with ED (EFD < 24) and without ED. Only 7% of men with ED moved from being "bothered" at 12 months to "no bother" at 24 months. There were no significant baseline predictors of sexual bother; baseline variables tested were: age, race, marital status, prostate-specific antigen (PSA) value, EFD, sexual desire, and intercourse satisfaction. The change in EFD scores was the only significant predictor of SB scores. CONCLUSIONS: Sexual bother increases post-RP, even in men with "good" erections postoperatively, and includes shame, embarrassment, and a reduction in general life happiness. Because men do not seem to "adjust" to ED, referral or evaluation should occur early in this population.

Chronology of erectile function in patients with early functional erections following radical prostatectomy.

INTRODUCTION: The association between erectile dysfunction (ED) and radical prostatectomy (RP) is well established. It is our clinical experience that some men who have functional erections in the days to weeks after RP go on to lose erectile function (EF) after the first 3 months postsurgery. AIM: To assess EF over a 12-month period in patients with functional erections at 3 months following RP. METHODS: As part of a large prospective quality-of-life (QOL) study of men undergoing RP at our institution, EF is measured postoperatively at regular time intervals using serial administration of the International Index of Erectile Function (IIEF) questionnaire. For study inclusion, patients had to have functional erections (a score 4 or 5 on IIEF question 3) at the third postoperative month, and have at least 12 months of follow-up. MAIN OUTCOME MEASURES: Assessment of EF and phosphodiesterase type 5 inhibitor (PDE5i) use at 3, 6, and 12 months after RP. RESULTS: At 3 months, 76 of 482 patients (16%) had functional erections. Between 3 to 6 months postoperatively, 20% of men deteriorated in their functional status. Of these men, 91% had functional erections at 1 year. Comparing patients who did not require PDE5i to obtain a functional erection at 3 months with those who did, the EF outcomes were superior at 6 months (80% vs. 72%, P = 0.74) and 12 months (100% vs. 88%, P = 0.33). CONCLUSION: The recovery of functional erections in the early postoperative phase, especially without the need for PDE5i, is a good prognostic indicator for EF at 12 months. However, a distinct cohort of men lose functional erections within 6 months after surgery. It is important to inform patients of this possibility, as it has an impact on their QOL and, potentially, on their compliance with post-RP therapy for ED.

Pretreatment prostate-specific antigen (PSA) velocity and doubling time are associated with outcome but neither improves prediction of outcome beyond pretreatment PSA alone in patients treated with radical prostatectomy.

PURPOSE: Controversy exists as to whether current pretreatment prostate-specific antigen (PSA) dynamics enhance outcome prediction in patients undergoing treatment for prostate cancer. We assessed whether pretreatment PSA velocity (PSAV) or doubling time (PSADT) predicted outcome in men undergoing radical prostatectomy and whether any definition enhanced accuracy of an outcome prediction model. PATIENTS AND METHODS: The cohort included 2,938 patients with two or more PSA values before radical prostatectomy. Biochemical recurrence (BCR) occurred in 384 patients, and metastases occurred in 63 patients. Median follow-up for patients without BCR was 2.1 years. We used univariate Cox proportional hazards regression to evaluate associations between published definitions of PSADT and PSAV with BCR and metastasis. Predictive accuracy was assessed using the concordance index. RESULTS: On univariate analysis, two of 12 PSADT and four of 10 PSAV definitions were univariately associated with both BCR and metastasis (P < .05). One PSADT and one PSAV definition had a higher predictive accuracy for BCR over PSA alone, and four PSAV definitions improved prediction of metastasis. However, the improvements in predictive accuracy were small, associated with wide CIs, and markedly reduced if additional predictors of stage and grade were included alongside PSA. Modeling with random variables suggests that similar results would be expected by chance. CONCLUSION We found no clear evidence that any definition of PSA dynamics substantially enhances the predictive accuracy of a single pretreatment PSA alone.

Preservation of ejaculation in patients undergoing nerve-sparing postchemotherapy retroperitoneal lymph node dissection for metastatic testicular cancer.

OBJECTIVES: To evaluate the clinical parameters associated with the recovery of ejaculation after nerve-sparing postchemotherapy retroperitoneal lymph node dissection (PC-RPLND) for nonseminomatous germ cell tumor. METHODS: We queried our institutional database for all patients who had undergone nerve-sparing PC-RPLND from 1995 to 2005 using a bilateral template. Nerve sparing was performed whenever technically feasible and oncologically prudent. Antegrade ejaculation was defined as any seminal fluid expulsion and was determined by patient report. We evaluated the recovery of antegrade ejaculation using clinical and pathologic parameters and fit a logistic regression model to determine which preoperative variables were associated with antegrade ejaculation. RESULTS: A total of 341 patients had undergone PC-RPLND during the study period, 136 (40%) with nerve-sparing techniques. Postoperative antegrade ejaculation was reported by 107 of 136 patients (79%) with information available. On multivariate analysis, a right-sided primary testicular tumor (odds ratio 0.4, 95% confidence interval 0.1-1.0, P = .044) and residual masses > or = 5 cm (odds ratio 0.1, 95% confidence interval 0.0-0.7, P = .020) were associated with retrograde ejaculation. However, 40 of 54 patients (74%) with right-sided primary tumors and 4 of 9 patients (44%) with a mass > or = 5 cm reported antegrade ejaculation. The 5-year relapse-free survival rate was 98%, with a median follow-up of 39 months (interquartile range 19-66). CONCLUSIONS: Nerve-sparing PC-RPLND is associated with excellent functional return of antegrade ejaculation, is feasible in select patients with bulky disease, and results in excellent oncologic outcomes.

Comprehensive prospective comparative analysis of outcomes between open and laparoscopic radical prostatectomy conducted in 2003 to 2005.

PURPOSE: In a nonrandomized prospective fashion we compared the oncological, functional and morbidity outcomes after laparoscopic and retropubic radical prostatectomy. MATERIALS AND METHODS: Between January 2003 and December 2005 a total of 1,430 consecutive men with clinically localized prostate cancer underwent radical prostatectomy, laparoscopic in 612 and retropubic in 818. The surgical approach was selected by the patient. Preoperative staging, respective surgical techniques, pathological examination and followup were uniform. Functional outcome was measured by patient completed health related quality of life questionnaire. RESULTS: Positive surgical margin rates (11%) and freedom from progression (median followup 18 months) were comparable between laparoscopic and retropubic radical prostatectomy (HR 0.99 for laparoscopic vs retropubic radical prostatectomy, p = 0.9). We found no significant association between operation type and time to postoperative potency (HR 1.04 for laparoscopic vs retropubic radical prostatectomy; 95% CI 0.74, 1.46; p = 0.8). Patients who underwent laparoscopic radical prostatectomy were less likely to become continent than those treated with retropubic radical prostatectomy (HR 0.56 for laparoscopic vs retropubic radical prostatectomy; 95% CI 0.44, 0.70; p <0.0005). Laparoscopic radical prostatectomy was associated with less blood loss (mean ml +/- SD 315 +/- 186 vs 1,267 +/- 660) and lower overall transfusion rate (3% vs 49%). No significant difference was noted in cardiovascular, thromboembolic and urinary complications. Emergency room visits and readmissions were higher after laparoscopic radical prostatectomy (15% vs 11% and 4.6% vs 1.2%, respectively). CONCLUSIONS: At our institution and during the study period laparoscopic radical prostatectomy and retropubic radical prostatectomy provided comparable oncological efficacy. Laparoscopic radical prostatectomy was associated with less blood loss and a lower transfusion rate, and higher postoperative hospital visits and readmission rate. While the recovery of potency was equivalent, that of continence was superior after retropubic radical prostatectomy.

The indication for postchemotherapy lymph node dissection in clinical stage IS nonseminomatous germ cell tumor.

BACKGROUND: The initial management of patients with clinical stage IS (cIS) nonseminomatous germ cell tumor (NSGCT) has evolved from primary retroperitoneal lymph node dissection (RPLND) to induction chemotherapy. The objectives of the current study were to determine the clinical outcome, patterns of relapse, and incidence of teratoma in the retroperitoneum for men with cIS NSGCT. METHODS: Between 1988 and 2004, 24 patients with cIS stage NSGCT were evaluated and treated at Memorial Sloan-Kettering Cancer Center. Clinical and pathologic data were obtained from the institutional prospective database. Seven patients underwent primary RPLND, and 17 patients received induction chemotherapy as initial management. Clinical outcomes, patterns of relapse, and pathologic findings were reported. RESULTS: Six of the 7 patients who underwent primary RPLND had viable germ cell tumor (GCT) present. Four of those patients did not receive adjuvant chemotherapy, and all experienced systemic relapse. Of the 17 patients who received induction chemotherapy, 3 patients underwent elective postchemotherapy RPLND (PC-RPLND), and 14 patients were followed expectantly. Four patients who were followed expectantly relapsed in the retroperitoneum and underwent PC-RPLND. Of the 7 patients who underwent PC-RPLND, 1 patient had fibrosis (14%), but 6 patients (86%) had teratoma, including 1 patient who also had a viable GCT in the retroperitoneum. Overall, the incidence of teratoma or viable GCT in the retroperitoneum after chemotherapy was 43% (6 of 14 patients). At a median follow-up of 35 months, 23 men remained alive, and 1 man had died of disease. CONCLUSIONS: The current data suggest that patients with cIS stage NSGCT will benefit from adjuvant PC-RPLND.

Nonrandomized comparison of primary chemotherapy and retroperitoneal lymph node dissection for clinical stage IIA and IIB nonseminomatous germ cell testicular cancer.

PURPOSE Patients with clinical stage (CS) IIA and IIB nonseminomatous germ cell tumor (NSGCT) with adenopathy more than 2 cm, multiple masses, elevated serum tumor markers, or disease outside the primary landing zone have increasingly been recommended to receive primary chemotherapy over time at our institution. The impact of these selection factors on the outcome of patients managed primarily by retroperitoneal lymph node dissection (RPLND) or chemotherapy was examined. PATIENTS AND METHODS Between 1989 and 2002, 252 patients with CS IIA and IIB NSGCT were referred to our institution for initial management, of whom 136 underwent RPLND and 116 received chemotherapy and postchemotherapy RPLND. Patient information was obtained from a prospective RPLND database. Results Proportionately more patients received chemotherapy over time (22% in 1989 to 1993 v 68% in 1999 to 2002), and the relapse-free survival (RFS) subsequently improved from 84% (1989 to 1998) to 98% (1999 to 2002; P = .004) without increasing the proportion who received any chemotherapy (70% v 79%; P = .16). By increasingly selecting patients with adverse features for primary chemotherapy, the RFS after RPLND improved from 78% to 100% (P = .019), but rates of pathologic stage II and retroperitoneal teratoma were unaffected. Retroperitoneal histology and RFS did not change over time for chemotherapy patients. Primary chemotherapy was associated with improved RFS compared with RPLND (98% v 79%; P < .001), but disease-specific survival did not differ significantly (100% v 98%; P = .3). CONCLUSION Patient selection factors have significantly improved the outcome of patients with CS IIA and IIB NSGCT without substantially increasing the proportion of patients exposed to chemotherapy.

Improved clinical outcome in recent years for men with metastatic nonseminomatous germ cell tumors.

PURPOSE: The integration of chemotherapy and surgery for metastatic nonseminomatous germ cell tumors (NSGCT) results in survival rates of greater than 80% overall. We evaluated men undergoing postchemotherapy retroperitoneal lymph node dissection (PC-RPLND) for NSGCT to determine associations between year of treatment and clinical outcome. PATIENTS AND METHODS: We evaluated 504 men who underwent PC-RPLND from 1989 to 2002 for NSGCT at our center. Data were obtained from our prospective surgical database and a multivariable logistic regression model was constructed to evaluate variables associated with 15-month relapse in 392 patients with complete data. RESULTS: From 1989 to 1997, clinical stage IIa, IIb, IIc, and III NSGCT was seen in 4%, 20%, 23%, and 47% of patients, respectively, compared with 18%, 26%, 11%, and 38%, respectively, from 1998 to 2002 (P < .001). The median prechemotherapy nodal size for 1989 to 1997 and 1998 to 2002 was 5.0 and 3.5 cm, respectively (P < .001). On multivariable analysis, prechemotherapy retroperitoneal nodal size (odds ratio [OR], 1.12; 95% CI, 1.03 to 1.21; P = .005) and presence of visceral metastasis (OR, 2.10; 95% CI, 1.02 to 4.33; P = .04) were significantly associated with 15-month relapse. Men who received a complete RPLND were significantly less likely to experience relapse (OR, 0.22; 95% CI, 0.09 to 0.50; P < .0005). CONCLUSION: In more recent years, men are presenting with less advanced metastatic NSGCT. This stage migration together with effective therapy has resulted in an improved relapse-free survival.

Incidence of metastatic nonseminomatous germ cell tumor outside the boundaries of a modified postchemotherapy retroperitoneal lymph node dissection.

INTRODUCTION: Modified template retroperitoneal lymph node dissections (RPLND) have become increasing applied in the postchemotherapy (PC) setting. We evaluated our experience with PC-RPLND to determine the incidence of disease extending outside the boundaries of a modified PC-RPLND. PATIENTS AND METHODS: From 1989 through 2003, a total of 532 men underwent PC-RPLND for metastatic nonseminomatous germ cell tumor (NSGCT). Of these, 269 (51%) had either viable germ cell tumor (GCT) or teratoma present in the RPLND specimen. After Institutional Review Board approval, clinical and pathologic data were obtained from our prospective surgical database. The incidence of retroperitoneal disease outside the boundaries of five modified templates was reported for the presence of viable GCT or teratoma. RESULTS: Of the 269 patients with viable GCT or teratoma, 20 to 86 (7% to 32%) patients had evidence of extratemplate retroperitoneal disease, depending on the boundaries of the modified template. There was no difference in the histologic distribution for patients with disease confined to or outside of the modified templates. Despite the absence of preoperative radiographic evidence of disease outside the boundaries of the Testicular Tumor Study Group template, the incidence of extratemplate metastasis for men with residual retroperitoneal masses less than 1, 1 to 2, 2 to 5, and more than 5 cm was two of 24 (8%), seven of 38 (18%), 27 of 92 (29%), and 14 of 55 (25%), respectively. CONCLUSION: Our data suggest a bilateral RPLND is a prudent approach for the management of men with metastatic NSGCT after chemotherapy, given that at least 7% to 32% of men will have teratoma or viable GCT outside the boundaries of a modified template.

Pretreatment nomogram predicting ten-year biochemical outcome of three-dimensional conformal radiotherapy and intensity-modulated radiotherapy for prostate cancer.

OBJECTIVES: To update our previously published nomogram predicting for biochemical outcome with 10-year data from a larger cohort of patients treated with three-dimensional conformal radiotherapy (RT) or intensity-modulated RT for localized prostate cancer. METHODS: From 1988 to 2004, 2253 patients were treated with three-dimensional conformal RT or intensity-modulated RT for clinical Stage T1-T3 prostate cancer. Prescription doses ranged from 64.8 to 86.4 Gy. The median follow-up time was 7 years. The nomogram was developed using a proportional hazards regression model predicting for the probability of biochemical relapse after RT according to the nadir plus 2 ng/mL definition of prostate-specific antigen (PSA) relapse. RESULTS: The 10-year PSA relapse-free survival rate was 62%. The nomogram incorporated the following variables to predict likelihood of PSA failure after RT: pretreatment PSA level, Gleason score, radiation dose, use of neoadjuvant androgen deprivation, and clinical stage. The concordance index of this long-term nomogram was 0.72. CONCLUSIONS: A nomogram predicting the 10-year probability of biochemical control after three-dimensional conformal RT or intensity-modulated RT for prostate cancer was reasonably accurate and discriminating. The nomogram also provided evidence that long-term biochemical control can be achieved after conformal RT for the treatment of localized prostate cancer.

Orgasm associated incontinence (climacturia) following radical pelvic surgery: rates of occurrence and predictors.

PURPOSE: Orgasm associated incontinence, that is the inadvertent leakage of urine at orgasm, has received little attention in the literature. We evaluated the rate of occurrence of orgasm associated incontinence following radical pelvic surgery as well as its associated factors and predictors. MATERIALS AND METHODS: From January 2005 to March 2006, 696 patients were evaluated for post-radical pelvic surgery sexual dysfunction. A database was created, and descriptive statistics, chi-square analysis and logistic regression analysis were used to evaluate associated factors and predictors. RESULTS: Of 475 patients 96 (20%) reported orgasm associated incontinence following radical pelvic surgery. The incidence was significantly less in the cystoprostatectomy group than in the open and laparoscopic radical prostatectomy groups (p <0.05). Orgasm associated incontinence was more commonly found within 12 months following surgery vs greater than 12 months (RR 0.81, 95% CI 0.72-0.92, p <0.01) and in patients with orgasm associated pain (RR 1.09, 95% CI 1.01-1.16, p <0.01) and penile length loss (RR 1.32, 95% CI 1.09-1.59, p <0.01). On multivariate analysis all factors associated on univariate analyses remained predictive. Orgasm associated incontinence was not associated with patient age, the degree of nerve sparing, surgical margin status, seminal vesicle or lymph node involvement, preoperative erectile function, nocturnal erections, libido level or daytime continence. CONCLUSIONS: Orgasm associated incontinence occurs in a fifth of men (96 of 475) following radical pelvic surgery. The incidence of orgasm associated incontinence is greater with radical prostatectomy than with radical cystectomy and it is unrelated to the type of prostatectomy performed (open vs laparoscopic). Orgasm associated incontinence is more likely to be reported within year 1 following surgery and in men who complain of orgasmic pain and/or penile shortening.

Clinical outcome following post-chemotherapy retroperitoneal lymph node dissection in men with intermediate- and poor-risk nonseminomatous germ cell tumour.

OBJECTIVE: To evaluate the outcome in patients treated with chemotherapy and retroperitoneal lymph node dissection (RPLND) after an initial diagnosis of International Germ Cell Cancer Collaborative Group (IGCCCG) intermediate- and poor-risk metastatic nonseminomatous testicular germ cell tumour (NSGCT), as the integration of chemotherapy and surgery in managing advanced NSGCT continues to develop. PATIENTS AND METHODS: Between 1989 and 2003, 157 patients initially diagnosed with IGCCCG intermediate- and poor-risk NSGCT had RPLND after chemotherapy at the authors' institution, with a median follow-up of 36 months. Progression-free probability (PFP) and disease-specific survival (DSS) were estimated using the Kaplan-Meier method. Cox proportional hazards regression analysis was used to assess the prognostic significance of risk factors for disease progression after RPLND. RESULTS: In all, 68 (43%) and 89 (57%) patients were assigned as intermediate- and poor-risk, respectively. At the time of RPLND the median residual retroperitoneal mass was 3.0 cm and 29 (19%) men had elevated serum tumour markers (alpha-fetoprotein, human chorionic gonadotrophin, or both). Retroperitoneal residual masses were completely resected in 147 (94%) patients; retroperitoneal histology revealed fibrosis in 73 (47%), teratoma in 63 (40%) and viable GCT in 21 (13%). The 5-year overall DSS and PFP were 81% and 70%, respectively. Patients with poor-risk NSGCT were at no greater risk of disease progression than those with intermediate-risk NSGCT. In a multivariate analysis, residual mass size, incomplete surgical resection and the presence of teratoma and viable germ cell cancer independently predicted disease progression after RPLND. CONCLUSIONS: Patients with advanced NSGCT have long-term freedom from disease progression when chemotherapy is combined with resection of residual masses. Our data suggest that the tumour response to chemotherapy, coupled with complete resection of all residual masses, predicts long-term freedom from disease progression.

Retroperitoneal lymph node dissection in patients with low stage testicular cancer with embryonal carcinoma predominance and/or lymphovascular invasion.

PURPOSE: The outcome after primary retroperitoneal lymph node dissection (RPLND) was analyzed in patients with clinical stage I-IIA nonseminomatous germ cell testicular cancer with embryonal carcinoma predominance (ECP) or lymphovascular invasion (LVI). MATERIALS AND METHODS: Between 1989 and 2002, 267 patients with clinical stage I-IIA nonseminomatous germ cell testicular cancer, and ECP and/or LVI underwent RPLND. Patient information was obtained from a prospective database. Median followup was 53 months. RESULTS: Overall 42% of patients had pathological stage (PS) II disease, of whom 54% had low volume (PN1) disease and 16% had retroperitoneal teratoma. The 5-year progression-free probability was 90% overall, 90% for PS I and 86% for PN1. All patients with relapse were continuously free of disease following standard chemotherapy with or without resection of residual masses and the 10-year actuarial overall survival was 100%. When adjuvant chemotherapy was restricted to patients with PN2 disease, the estimated 5-year relapse rate was 9% and an estimated 72% of patients avoided chemotherapy. CONCLUSIONS: The low risk of systemic relapse in patients with PS I and PN1 after RPLND alone combined with the 16% incidence of retroperitoneal teratoma and the favorable morbidity profile supports RPLND over primary chemotherapy for the treatment of patients with low stage disease with ECP and/or LVI who are not candidates for surveillance. An estimated 72% of patients are spared the potential toxicity of chemotherapy if adjuvant therapy is restricted to patients with PN2. After primary RPLND and selective adjuvant chemotherapy late recurrence is distinctly uncommon and long-term cancer control is anticipated in essentially all patients.

Retroperitoneal lymph node dissection for nonseminomatous germ cell testicular cancer: impact of patient selection factors on outcome.

PURPOSE: To investigate the impact of patient selection criteria on the outcome of patients with nonseminomatous germ cell testicular cancer (NSGCT) treated by primary retroperitoneal lymph node dissection (RPLND). Since 1999, our criteria have excluded patients with persistent postorchiectomy elevation of serum tumor markers (STM) or clinical stage (CS) IIB disease from RPLND. PATIENTS AND METHODS: Between 1989 and 2002, 453 patients underwent primary RPLND at our institution for CS I to IIB NSGCT. Patient information was obtained from a prospective database. Retroperitoneal pathology and relapse rates were compared for patients treated before and after application of the current selection criteria in 1999. RESULTS: By excluding patients with elevated STM or CS IIB disease after 1999, the proportion of pathologic stage II patients with low-volume (pN1) retroperitoneal disease increased significantly (40% before 1999 v 64% after 1999; P = .01), without significantly affecting the rate of retroperitoneal teratoma (21% v 22%, respectively; P = .89) or pathologic stage I disease (56% v 67%, respectively; P = .06). For patients who did not receive adjuvant chemotherapy, the 4-year progression-free probability improved significantly from 83% before 1999 (95% CI, 79% to 88%) to 96% after 1999 (95% CI, 91% to 100%; P = .005). Elevated postorchiectomy STM (P < .0001), clinical stage (P = .0002), and pre-1999 RPLND (P = .05) were independent pretreatment predictors of progression. CONCLUSION: Excluding patients with CS IIB disease or elevated postorchiectomy STM from primary RPLND has had a favorable impact on the extent of retroperitoneal disease and has significantly reduced the risk of relapse after RPLND. For patients with normal STM and CS I to IIA disease, the low rate of systemic progression and 22% incidence of retroperitoneal teratoma supports RPLND as the preferred primary intervention.
