Abstract
OBJECTIVES To know the necessary information to reproduce the results found in the literature on active surveillance (AS) in prostate cancer (PCa) in our own center so that the information would be objective and correctly given to the patients. We have aimed to study the percentage of candidates for AS chosen in our setting, and the data on infrastaging, subgrading and prediction of insignificant PCa, debugging the predictive value of clinical variables to improve our selection criteria and finally to analyze the results of our patients enrolled in AS. MATERIALS AND METHODS A retro- and prospective review of our data bases was performed. A one-year period was analyzed to know AS candidates. Analysis of our radical prostatectomy specimens for infrastaging, subgrading and prediction of insignificant PCa (Epstein's criteria) was made as well as a uni/multivariate analysis of clinical variables in patients with insignificant PCa in the specimen. A prospective validation was performed with overall survival and survival free of active treatment (SFAT) as endpoints in patients enrolled in AS. RESULTS Between October-2010/October-2011, 44.7% of our PCa were candidates for AS, but only 11.2% choose it. The percentages found for infrastaging, subgrading and prediction of insignificant PCa were 14%, 31.4% and 55.7%, respectively. However, only just 6 patients (6.97%) had≥pT3a+Gleason≥7+volume>0.5cc PCa. The multivariate analysis showed that PSA density and number of affected cores were independent predictors of insignificant PCa. With a mean follow-up of 36±39months, 63 out of 232 patients enrolled in AS went on to active treatment (27.1%), with only 13 due to anxiety without pathologic progression. Median time of SFAT was 72.7 months (CI 95% 30.9-114.4). SFAT at 24 months was 76.4% (69.7-83.1%) and at 48 months 58.1% (48.8-67.4%). Only 10 patients died (4.3%), 9 due to causes different of PCa. Estimated overall survival at 5 years was 92.8% (CI 95% 86.7-98.9%). CONCLUSIONS It should be mandatory to have the exact knowledge of the local data of each Center in order to objectively inform patients about prostate biopsy efficiency, and if percentages of infrastaging, subgrading and prediction of insignificant PCa are in accordance with the literature. At 3 years, we reproduced the results of the longest series of AS, so we have ascertained that our AS protocol can be implemented with increasingly more patients.

Abstract
INTRODUCTION We analyse our experience in the conservative surgical management of penile cancer and/or penile skin pathologies at our institution. MATERIAL AND METHODS We have retrospectively reviewed all the skin grafting procedures performed in penile surgery in the last eight years. We show the indications and results of these surgical procedures and the detailed surgical technique originally described by Bracka. RESULTS Ten patients had several types of partial penile removal surgery followed by free-skin graft resurfacing, creating a neoglans. There were no relevant or major complications; two patients suffered partial necrosis of the skin graft. There was no local recurrence. 6 Patients returned to normal sexual activity after complete healing. CONCLUSIONS There is a significant number of patients with penile cancer and/or other penile skin pathologies who can undergo definitive and non-mutilating surgery with excellent oncologic, cosmetic and functional results with skin grafting.

Abstract
PURPOSE To determine our results in high risk (HR) prostate cancer (PCa) patients treated with radical prostatectomy (RP) and to establish preoperative prognosis factors. MATERIAL AND METHODS Retrospective study of 925 RP. Mean follow-up for the HR group was 89.8+/-53.6 months. Following NCCN criteria, we operated 210 (22.7%) HR and 715 (77.3%) low/intermediate risk patients. End point was metastatic progression. Kaplan-Meier method for survival comparison among groups and Cox regression model for multivariate analysis of preoperative prognostic factors were used. RESULTS Revised period; 1986-2007. Fifty-four patients (25.7%) were free of disease and 8 patients (3.8%) died for other causes free of disease. Disease progressed in 148 patients (70.5%); death due to tumour progression occurred in 42 cases (20%) and due to other causes in 25 patients (11.9%). Seventy-nine patients in HR group (38%) vs 549 low/intermediate risk group (78.5%) did not deserve further treatments (p<0.001). The uni and multivariate analysis for metastatic progression showed both Gleason score at biopsy (RR=1.922; 95% CI 1.106-3.341, p=0.020) and clinical stage (RR=2.290; 95% CI 1.269-4.133, p=0.006) showed independent prognostic value for metastatic progression, but not PSA. CONCLUSIONS A HR patient can be cured in a third of the cases and will need multimodal treatments in more than half of the times. We prompt surgery in a young healthy patient with a resectable tumour, mainly if just one bad prognostic factor is present and defiantly if this is just PSA elevation.

Abstract
OBJECTIVE To retrospectively evaluate the toxicity of low-dose-rate brachytherapy and to relate it to the dose-volume to organs at risk. MATERIAL AND METHODS We study 160 patients with early prostate cancer, treated with (125)-I implants. Most of them were T1c (63.1%), T2a (35.6%) and Gleason < or =6 (96.2%). Median PSA was 7.2 ng/ml (2.3-13.5); 85.6% were lowrisk cases and 14.4% high-risk cases. Mean follow-up was 24 months (7-48). RESULTS Acute urinary toxicity related to urological quality of life (UQL=CVU) was tolerable in 75% and unsatisfactory in 25%. Urinary retention was present in 6.9%. IPSS, V100 and D90 were related to the urinary toxicity grade. Rectal toxicity (RTOG) G2 was 0.6%. Sexual potency showed no changes with regard to the basal in 69%. Actuarial biochemical control was 89.8% at four years. CONCLUSIONS Brachytherapy with (125)-I seeds yields acceptable toxicity and excellent biochemical control.

Abstract
PURPOSE We evaluate the safety and efficacy of conservative elective treatment of upper urinary tract tumors, and determine predictive factors for recurrence and progression to optimize indications of this type of treatment. MATERIALS AND METHODS Since 1984 we have performed a prospective study of conservative treatment of single, low grade and stage, less than 3 cm. upper tract tumors. The study includes 54 patients with a normal contralateral kidney who had been followed for more than 36 months. Open conservative surgery was performed in 31 cases and endourological surgery in 23. Minimum followup was 36 months, maximum 210 and mean 84.8. Univariate and multivariate analyses of recurrence and progression were performed in relation to age, sex, association with a bladder tumor, bladder tumor stage and grade, sequence of bladder tumor in relation to upper urinary tract tumor, number of previous bladder tumor recurrences, association with bladder carcinoma in situ, upper urinary tract tumor grade, stage, location, size and therapy, and upper urinary tract cytology. RESULTS Of the 54 patients 19 (35%) had recurrence, which was bilateral recurrence in 4, and progression occurred in 9 (16%). At the end of analysis 44 (62.9%) patients were disease-free and alive at a mean time of 92.88 months, 13 (24%) died disease-free at a mean of 72.7 months and 7 (12.9%) died of disease at a mean of 97.85 months. Cause specific mortality occurred in 7 (12.9% cases). Among the 54 initially conservatively treated units 42 (77.7%) kidneys were ultimately preserved. On univariate and multivariate analysis tumor location in the renal pelvis and association with a previous multi-recurrent bladder tumor were variables significantly related to recurrence and progression, as well as bilateral recurrence. CONCLUSIONS Conservative treatment is an optional approach for select upper urinary tract tumors. The strongest risk factors for recurrence and progression were association with a previous multi-recurrent bladder tumor and tumor location in the renal pelvis but these conditions were also the strongest risk factors for bilateral recurrence. Conservative treatment can also be recommended in these cases but only with compliant patients and close followup.

Abstract
PURPOSE We prospectively validated the association of local tumor stage and grade as a predictive factor for occult lymph node micrometastasis in patients with penile carcinoma and clinically negative lymph nodes. MATERIALS AND METHODS In a retrospective study of 66 patients we demonstrated the predictive value of the association of local tumor stage and grade for occult micrometastasis, identifying 3 risk groups. A therapy strategy was designed according to these risk groups. A total of 37 consecutive patients were included in a prospective study in which the same criteria for risk group allocation and the same therapeutic recommendations were used as in the retrospective study. RESULTS In the prospective study we noted positive lymph nodes in 11% of stage T1, 63% of stages T2-3, 15% of grade 1, 67% of grade 2 and 75% of grade 3 cases. The incidence of positive nodes was 0% in the low, 83.3% in the high and 33.3% in the intermediate risk group. These rates were similar to those in the retrospective study with no significant difference. CONCLUSIONS The predictive value of the association of local tumor stage and grade for occult lymph node micrometastasis was validated in a prospective study. This factor allows the differentiation of 3 risk groups of patients with high reliability in the low and high risk groups. However, other prognostic factors are needed in the intermediate risk group to improve the prediction of lymph node involvement.

Effectiveness of a single immediate mitomycin C instillation in patients with low risk superficial bladder cancer: short and long-term followup. J Urol 1999; 161:1120-3.

Abstract
PURPOSE We analyze the impact of a single mitomycin C instillation in patients with low risk superficial bladder cancer with short and long-term followup. MATERIALS AND METHODS A total of 131 patients with low risk superficial bladder cancer were included in a prospective randomized controlled trial. All patients had a 3 cm or less single, papillary, primary or recurrent tumor and were disease-free for more than 1 year. Patients with muscular invasion, G3 tumor or bladder carcinoma in situ on pathological examination were excluded from study. The tumor was completely resected before patients were randomized into 2 arms of no further treatment (control group) and a single immediate instillation of 30 mg mitomycin C (mitomycin C group). Recurrences were considered early within the first 2 years of followup. RESULTS At 24-month followup the recurrence-free interval was significantly increased, and recurrence, and recurrence and tumor per year rates were decreased in the mitomycin C compared to the control group. However, at long-term followup these differences were not statistically significant and the recurrence-free interval curves were parallel. A shorter hospital stay and catheterization period were noted in the mitomycin C group compared to the control group, which were not significant. Early recurrences were concentrated in the first year in the control but not in the mitomycin C group. A significant relationship between early and late recurrences was found in the mitomycin C but not in the control group. CONCLUSIONS Our analysis confirms the positive effect of a single immediate mitomycin C instillation in patients with low risk superficial bladder cancer. This benefit is limited to early recurrence and is not maintained with long-term followup. Thus, this approach is an alternative to observation or endovesical chemotherapy. Our study also suggests that cell implantation as a mechanism of early recurrence can be controlled with a single mitomycin C instillation.

Abstract
PURPOSE We analyzed the long-term results of radical transurethral resection for the treatment of a large series of patients with muscle infiltrating bladder cancer entered into a prospective study to determine progression predictive factors. MATERIALS AND METHODS The study included 133 patients with invasive bladder cancer treated by radical transurethral resection who had negative biopsies of the muscle layer of the tumor bed. Followup was more than 5 years for all subjects and more than 10 years in 59 (44.4%). A comparative nonrandomized study was performed of a control group of 76 patients with invasive pathological stage pT2-3a, N0-3 bladder cancer treated by cystectomy. In those patients treated by radical transurethral resection univariate and multivariate analyses were performed to establish clinical progression predictive factors. RESULTS At 5 and 10 years of followup cause specific survival rates were 80.5 and 74.5%, and bladder preservation rates were 82.7 and 79.6%, respectively. No significant difference was noted in terms of cause specific survival, with respect to the control group. The initial presence of associated bladder carcinoma in situ was the only independent progression predictive factor. CONCLUSIONS For patients with invasive bladder cancer radical transurethral resection is justified when the tumor is clinically limited to the muscular layer and when all biopsies of the periphery and depth of the tumor bed show muscular tissue negative for tumor cells. Patients with initial associated bladder carcinoma in situ should not be excluded from this treatment but endovesical bacillus Calmette-Guerin immunotherapy should be administered and a closer followup is recommended.

Upper urinary tract involvement in patients with bladder carcinoma in situ (Tis): its impact on management. Urology 1997; 49:347-52.

Abstract
OBJECTIVES To analyze the biologic behavior and etiologic mechanism of upper-tract involvement in patients with bladder cancer in situ (Tis) and its impact on management of these patients. METHODS One hundred thirty-eight patients with bladder Tis, 786 with superficial bladder cancer, and 179 patients with invasive bladder cancer treated by cystectomy were studied: 34 (24.6%), 18 (2.3%), and 7 (3.9%) developed upper-tract involvement in each group, respectively. Sixty-three patients with primary urothelial upper-tract tumors were also studied. Taking progression-free survival as an end point, univariate and multivariate analyses were performed. RESULTS The upper-tract recurrence rate was significantly higher in patients with bladder Tis than in patients with superficial bladder tumors (P <0.001); it was also significantly higher in patients treated with cystectomy because of bladder Tis compared with those treated because of invasive tumors (P <0.01). Patients with bladder Tis and upper-tract involvement showed high rates of upper-tract bilaterality (32.3%) and prostate involvement (67.4%). On pathologic examination, the upper tract showed predominantly superficial (Ta-T1-Tis) tumors (67.4%) and distal ureter location as the only finding (47%). In patients with bladder Tis, upper-tract involvement alone does not have a negative impact on the survival rate according to univariate and multivariate analysis (P = NS). CONCLUSIONS In patients with bladder Tis, upper-tract involvement represents a diffuse process; therefore, a close evaluation of both the prostate and the upper tract is recommended. Upper-tract involvement has no impact on bladder-preservation strategy. Many of these patients could also be offered a conservative management for the involved upper tract.

Extravesical involvement in patients with bladder carcinoma in situ: biological and therapy implications. J Urol 1996; 155:895-9; discussion 899-900.

Abstract
PURPOSE The biological and therapeutic implications of extravesical involvement in patients with bladder carcinoma in situ were analyzed. MATERIALS AND METHODS Of 138 patients with bladder carcinoma in situ 87 (63%) had extravesical involvement, including the prostate in 53, the upper urinary tract in 11 and both structures in 23 (pan-urothelial involvement). With survival free of disease as an end point, univariate and multivariate analyses were done. RESULTS Patients with extravesical involvement had worse survival than those with bladder carcinoma in situ alone (p < 0.001). In multivariate analysis prostate involvement (p = 0.0007) and pan-urothelial involvement (p = 0.0001) were selected as significant variables. When pathological patterns were considered prostatic stromal invasion (p = 0.0002) was the only variable selected. With these data 3 patient groups with disease mortality risk were defined. CONCLUSIONS Prostate involvement and pan-urothelial involvement behave as independent prognostic factors, with the latter probably reflecting an extremetly diffuse character of carcinoma in situ. However, the upper urinary tract had no influence on survival. In patients with upper urinary tract and/or prostatic involvement limited to the mucosa treatment can be conservative. Patients with ductal or stromal involvement should undergo radical treatment. For upper tract involvement conservative approaches may be considered if there are no radiological signs of invasion or low grade tumor.

Abstract
PURPOSE The prognostic value of prostate involvement in patients with superficial bladder cancer was analyzed. MATERIALS AND METHODS We studied 96 patients with prostate involvement. Taking progression-free survival rate as an end point, univariate and multivariate analyses were done. RESULTS The presence or absence of bladder carcinoma in situ is related to poor and good prognoses, respectively (p < 0.001). Stromal invasion (p < 0.001) and pan-urothelial involvement (p = 0.03) were also identified as independent factors of poor prognosis. CONCLUSIONS Patients with tumor limited to the mucosa can be treated conservatively. Cystoprostatectomy can be performed in patients with ductal involvement. The prognosis of patients with stromal invasion is poor despite radical treatment.

Abstract
We report 18 consecutive patients with testis cancer and retroperitoneal residual masses with normal tumor markers, who underwent lymphadenectomy. Aiming to preserve the antegrade ejaculation, we carried out surgical modifications which basically attempt to preserve: (1) both sympathetic lumbar trunks, (2) the superior hypogastric plexus and (3) some of the postganglionic branches. With a mean follow-up of 28.1 months (range 6-62 months), 15 (83.3%) of the 18 patients preserved ejaculation, without significant differences between ejaculation volumes before and after lymphadenectomy. At the present time, 3 of 4 possible patients have fathered children. Mass size seems to be an important predictive factor of ejaculation preservation. One patient relapsed in the retroperitoneal dissection area, representing a recurrence rate of 5.5%. The disease-free survival rate was 94.4%, and 1 patient died due to disease progression with lung recurrence. Thus preservation of ejaculation was possible in most of these patients.

Abstract
A prospective study was done to evaluate treatment of patients with muscle-infiltrating bladder cancer by transurethral resection exclusively. Inclusion criteria for this study were histological confirmation of muscular bladder infiltration, endoscopic radical transurethral resection, disappearance of hardened areas after transurethral resection, and negative biopsies of the depth and periphery of the tumor bed. The study began in April 1981. The average followup in series 1 (April 1981 to December 1986, 59 patients) was 55.4 months. Actually, of the patients 31 (52.5%) are without evidence of recurrence and 28 (47.5%) have recurrent disease. Of the latter patients 11 (18.6%) had invasive bladder recurrence, including 7 (11.9%) who had recurrence at 3 months, which indicated clinical understaging. Three patients (5%) had metastases without bladder tumor. The remaining 14 patients (23.7%) had superficial bladder recurrence. The overall survival rate was 83% (49 of 59 patients) and 43 patients (72.8%) still retain the bladder. The present data are confirmed by the results of series 2 (December 1986 to August 1989). Therefore, the data would justify conservative management in a selected group of patients with muscle-infiltrating bladder cancer.

Abstract
Of the 101 patients with penile cancer, we have analyzed 66 from whom we had enough information: 42 (63.3%) patients with corpora cavernosa invasion (T2-3) and 24 (36.6%) without (T1). With respect to the tumor grade, in 36 (54.3%) patients it was well differentiated (G I), in 23 (34.8%) moderately (G II) and in 7 (10.6%) poorly differentiated (G III). We also analyzed the inguinal lymph node condition. Of the 66 patients, 28 (42.4%) developed nodal metastases, and 38 (57.6%) were considered free of nodal metastases and disease with an average follow-up of 76.2 months (range 38-192). The presence of metastatic nodes was influenced by both tumor stage and grade with significant differences between T2-3 and T1 (p = 0.001) and between G II-III and G I (p < 0.01), but each of them alone was not a sufficiently reliable predictive factor. In order to associate local stages and tumor grades in relation to the presence of metastatic nodes, we checked that none of the patients with T1, G I (group 1) developed nodal metastases, and therefore, 'wait and see' should be the suitable approach. Twenty (80%) of the patients with T2-3, G II-III (group 2) developed metastatic lymph nodes, thus, in this group, an early lymphadenectomy should be performed. In the remaining 22 patients with T1, G II-III and T2, G I (group 3), 8 (36.4%) showed metastatic lymph nodes; in this group, other factors such as age, cultural level and obesity should be taken into account when deciding on lymphadenectomy.

Abstract
Of our 276 patients with superficial bladder carcinoma, 242 were male, and 36 of these had recurrence in prostatic urethra, 26 with macroscopic tumors, and 10 with tumors in situ (TIS). These recurrences represent an incidence of 13.3%, with an average follow-up of 34.3 months. When the urethral tumor was limited to the mucosa, we chose conservative therapy, and the patients entered a random program with Mitomycin or Adriamycin administered endovesically. With this program, we could control the disease in 59.3% of the patients. However, 22.2% of them had recurrence with prostatic stromal infiltration, so that we performed a more exhaustive exploration of the prostate, taking biopsies not only at the 5 and 7 o'clock positions, but also making a wider resection in order to find the incipient infiltration of the prostatic stroma, and trying to avoid a possible understaging. When the urethral tumor had infiltrated the prostatic stroma, we performed cystoprostatourethrectomy, getting a survival rate free of disease of 40%. An association with vesical TIS was detected in 61.1% of these patients, with terminal ureteral tumor in 8.3% and with the anterior urethra in 11.1%, showing the diffuse pattern of the disease. We conclude that when recurrence of prostatic urethra is present, it is necessary to monitor the whole urothelium during follow-up.

Abstract
In a sample of 306 patients with superficial bladder tumors (Ta, Tl), 48 were affected by associated carcinoma in situ (TIS). We included 40 of them in a random program with Mitomycin C or Adriamycin, administered endovesically. We found that those patients with associated TIS whose progression rate had increased to 37.1% compared to 8.8% in the original series (p less than 0.01), had a worse prognosis. Besides, 10 of them required radical cystectomy. With this chemotherapy program, we achieved a high rate of complete response (70%), but its duration was limited by a recurrence rate of 42.9%, with a time free of disease of 26.2 months. In the whole group, the survival rate free of disease was 77.5%, with an average follow-up of 37.3 months. On the other hand, we found extravesical recurrences not only in the prostatic urethra (13; 32.5%) but also at the end of the ureter (3; 7.5%).
