ABSTRACT

OBJECTIVE: Histological details of positive surgical margins in radical prostatectomy specimens have been related to outcome after surgery in rare studies recently published. Our objective is to assess whether the status of surgical margins, the extent and the Gleason score of positive margins, and the extent of the extraprostatic extension are predictive of biochemical recurrence post-radical prostatectomy. MATERIALS AND METHODS: Three hundred sixty-five radical prostatectomy specimens were analyzed. The length of the positive surgical margin and extraprostatic extension and the Gleason score of the margin were recorded. Statistical analyses examined the predictive value of these variables for biochemical recurrence. RESULTS: 236 patients were stage pT2R0, 58 pT2R1, 25 pT3R0 and 46 pT3R1. Biochemical recurrence occurred in 11%, 31%, 20% and 45.7% of pT2R0, pT2R1, pT3R0 and pT3R1, respectively. The extent of the positive surgical margins and the Gleason score of the positive surgical margins were not associated with biochemical recurrence in univariate analysis in a mean follow up period of 35.9 months. In multivariate analyses, only the status of the surgical margins and the global Gleason score were associated with biochemical recurrence, with a risk of recurrence of 3.1 for positive surgical margins and of 3.8 for a Gleason score > 7. CONCLUSION: Positive surgical margin and the global Gleason score are significant risk factors for biochemical recurrence post-radical prostatectomy, regardless of the extent of the surgical margin, the extent of the extraprostatic extension, or the local Gleason score of the positive surgical margin or extraprostatic tissue. pT2R1 disease behaves as pT3R0 and should be treated similarly.

ABSTRACT

Introduction

The widespread screening programs prompted a decrease in prostate cancer stage at diagnosis, and active surveillance is an option for patients who may harbor clinically insignificant prostate cancer (IPC). Pathologists include the possibility of an IPC in their reports based on the Gleason score and tumor volume. This study determined the accuracy of pathological data in the identification of IPC in radical prostatectomy (RP) specimens. Materials and Methods

Of 592 radical prostatectomy specimens examined in our laboratory from 2001 to 2010, 20 patients harbored IPC and exhibited biopsy findings suggestive of IPC. These biopsy features served as the criteria to define patients with potentially insignificant tumor in this population. The results of the prostate biopsies and surgical specimens of the 592 patients were compared. Results

The twenty patients who had IPC in both biopsy and RP were considered real positive cases. All patients were divided into groups based on their diagnoses following RP: true positives (n = 20), false positives (n = 149), true negatives (n = 421), false negatives (n = 2). The accuracy of the pathological data alone for the prediction of IPC was 91.4%, the sensitivity was 91% and the specificity was 74%. Conclusion

The identification of IPC using pathological data exclusively is accurate, and pathologists should suggest this in their reports to aid surgeons, urologists and radiotherapists to decide the best treatment for their patients. .

ABSTRACT

INTRODUCTION: The aim of this prospective study was to compare the advantage of performing prostate biopsy with a greater number of cores using the classic sextant procedure, with the aim of reducing false negative results. MATERIALS AND METHODS: 100 prostates were acquired from consecutive radical prostatectomies performed by the same surgeon. Fourteen cores were obtained on the bench following surgery using an automatic pistol with an 18-gauge needle. Six of these cores were obtained according to the sextant technique, as described by Hodge et al.; with the addition of a further three lateral cores from each lobe and one from the bilateral transition zone. The whole gland and the fragments were assessed by the same pathologist. An analysis of the frequency of the cancers identified in the cores of the sextant and the extended biopsies was undertaken and the results evaluated comparatively. The chi-square test was used for the comparative analysis of the cancer detection rate, according to the technique used. RESULTS: When 6 cores were removed, the positive cancer rate was 75%, which was increased to 88% when 14 cores were (p < 0.001). The withdrawal of 14 cores resulted in a significant 13% (95% CI [5%-21%]) increase in the positive rate of cancer detection. CONCLUSION: Extended biopsy, with the removal of 14 cores, is more efficient than the sextant procedure in improving the rate of prostate cancer detection.

ABSTRACT

OBJECTIVE: Preoperative determination of prostate cancer (PCa) tumor volume (TV) is still a big challenge. We have assessed variables obtained in prostatic biopsy aiming at determining which is the best method to predict the TV in radical prostatectomy (RP) specimens. MATERIALS AND METHODS: Biopsy findings of 162 men with PCa submitted to radical prostatectomy were revised. Preoperative characteristics, such as PSA, the percentage of positive fragments (PPF), the total percentage of cancer in the biopsy (TPC), the maximum percentage of cancer in a fragment (MPC), the presence of perineural invasion (PNI) and the Gleason score were correlated with postoperative surgical findings through an univariate analysis of a linear regression model. RESULTS: The TV correlated significantly to the PPF, TPC, MPC, PSA and to the presence of PNI (p < 0.001). However, the Pearson correlation analysis test showed an R2 of only 24%, 12%, 17% and 9% for the PPF, TPC, MPC, and PSA respectively. The combination of the PPF with the PSA and the PNI analysis showed to be a better model to predict the TV (R2 of 32.3%). The TV could be determined through the formula: Volume = 1.108 + 0.203 x PSA + 0.066 x PPF + 2.193 x PNI. CONCLUSIONS: The PPF seems to be better than the TPC and the MPC to predict the TV in the surgical specimen. Due to the weak correlation between those variables and the TV, the PSA and the presence of PNI should be used together.

ABSTRACT

OBJECTIVE: We aim at determining the prognostic value of squamous differentiation in patients with transitional cell carcinoma (TCC) of the bladder that were treated with radical cystectomy. MATERIALS AND METHODS: From January 1993 to January 2005, we retrospectively selected 113 patients. Correlations among squamous differentiation with other clinical and pathological features were assessed by both chi-square and Fisher tests. The Kaplan-Meier method was used to evaluate survival curves and statistical significance was determined by the log-rank test. Multivariate analysis was performed through a Cox proportional hazards regression model. RESULTS: Squamous differentiation was observed in 25 (22.1%) of the 113 patients. This finding was significantly related only to the pathological stage. Mean follow-up after cystectomy was 31.7 +/- 28.5 months. Disease recurrence occurred in 16 (64%) and 30 (34%) patients with and without squamous differentiation (log-rank test, p = 0.001), and mortality occurred in 10 (40%) and 14 (16%) of the patients with and without squamous differentiation respectively. Univariate analysis revealed that pathological stage, squamous differentiation, tumor size and lymph node involvement were significant predictors of cancer-specific survival. However, only squamous differentiation and tumor size were independent prognostic variables on multivariate analysis. CONCLUSIONS: Squamous differentiation was an independent prognostic factor for cancer specific survival in patients with bladder cancer treated with radical cystectomy. Further studies with a larger number of patients are necessary to confirm these results.

ABSTRACT

PURPOSE: The biological behavior and clinical outcome of renal cell carcinoma are difficult to predict. We investigated the prognostic impact of clinicopathological variables to establish a risk stratification model to predict recurrence and survival rates. MATERIALS AND METHODS: We studied 230 patients with renal cell carcinoma (stages T(1-4) N(x) M(0)) who underwent radical nephrectomy and/or nephron sparing surgery, and were followed for a median of 48 months (range 3 to 140). Univariate and multivariate analyses were performed, and the influence of clinical presentation, histological tumor size, tumor grade, lymph node involvement and microvascular tumor invasion on disease-free and cancer specific survival curves was determined. A composition model based on independent prognostic variables was then created to stratify tumors into low, intermediate and high risk of progression. RESULTS: The tumor recurrence rate was 17% (39 of 230) and the cancer specific mortality rate was 13% (31 of 230). Multivariate analyses determined that microvascular tumor invasion, tumor grade and tumor size were the only independent prognostic factors. Disease-free survival rates for low, intermediate and high risk tumors were 94.7%, 56.8% and 13.1%, respectively. Cancer specific survival rates were 94.7%, 61.7% and 32.0%, respectively. CONCLUSIONS: Tumor size, Fuhrman grade and microvascular tumor invasion are strong and independent predictors of survival of patients with renal cell carcinoma. Risk assessment and stratification based on this triad of pathological features may allow better individualization of followup schedules and trials of adjuvant treatment for patients with renal cell carcinoma.

ABSTRACT

OBJECTIVE: Determine the prognostic value of perineural invasion (PNI) in patients with transitional cell carcinoma (TCC) of the bladder treated with radical cystectomy. MATERIALS AND METHODS: From January 1993 to January 2005, 113 people were selected from 153 patients with TCC of the bladder treated with radical cystectomy. The association between the presence of PNI and other pathologic characteristics were analyzed through Fisher exact test. The Kaplan-Meier method was utilized to assess the survival curve and the statistical significance was determined by the Breslow test. The multivariate analysis was performed through the Cox regression model. RESULTS: The PNI was identified in 10 (8.8%) of the 113 patients. This variable significantly related to the microvascular invasion and to tumor staging. The mean segment after surgery was 31.7 +/- 28.5 months. Recurrence occurred in 5 (50%) and in 41 (39.8%) patients (p=0.363) and mortality occurred in 2 (20%) and 22 (21.9%) patients (p=0.606) with or without PNI respectively. In Cox regression analysis, patients with PNI presented with 1.53 times (IC 95% 0.60 to 3.91; p=0.371) and 1.60 times (IC 95% 0.37 to 6.95; p=0.532) the risk of recurrence and mortality when compared to patients without PNI. CONCLUSIONS: The PNI does not constitute an independent variable of disease-free and cancer specific survival in patients with TCC of the bladder treated with radical cystectomy.

ABSTRACT

OBJECTIVE: Recto-urethral fistula formation following radical prostatectomy is an uncommon but potentially devastating event. There is no consensus in the literature regarding the treatment of these fistulas. We present here our experiences treating recto-urethral fistulas. MATERIAL AND METHODS: We analyzed 8 cases of rectourethral fistula treated at our institution in the last seven years. Seven of the patients underwent repair of the fistula using the modified York-Mason procedure. RESULTS: The causes of the fistula were radical retropubic prostatectomy in five patients, perineal debridement of Fournier's gangrene in one, transvesical prostatectomy in one and transurethral resection of the prostate in the other patient. The most common clinical manifestation was fecaluria, present in 87.5% of the cases. The mean time elapsed between diagnosis and correction of the fistula was 29.6 (7-63) months. One spontaneous closure occurred after five months of delayed catheterization. Urinary and retrograde urethrocystography indicated the site of the fistula in 71.4% of the cases. No patient presented recurrence of the fistula after its correction with the modified York-Mason procedure. CONCLUSION: The performance of routine colostomy and cystostomy is unnecessary. The technique described by York-Mason permits easy access, reduces surgical and hospitalization times and presents low complication and morbidity rates when surgically correcting recto-urethral fistulas.

OBJETIVO: As fístulas reto-uretrais são de acesso difícil e por vezes complexo, sendo seu fechamento espontâneo raro. Com o diagnóstico precoce e aumento do número de intervenções, principalmente a cirurgia por adenocarcinoma da próstata localizado, sua incidência apesar de rara vem crescendo. Nós demonstramos a nossa experiência dos casos de fístulas reto-uretrais entre 2000 a 2006 com uma serie de oito pacientes, sendo que sete realizaram correção da fístula pela Técnica de York Mason modificada. MATERIAL E MÉTODO: Nos retrospectivamente analisamos os prontuários de todos os casos de fístulas reto-uretrais tratados no nosso serviço no período de 2000 a 2006. Sete de oito pacientes realizaram reparo da fístula através do procedimento de York Mason modificado. RESULTADOS: Cinco pacientes tiveram a fístula como conseqüência da Prostatectomia Radical Retropúbica, sendo os outros três após debridamento devido a Fasceíte de Fournier, Prostatectomia Transvesical e Ressecção Transuretral da Próstata. A fecalúria foi o quadro clínico prevalente em 87,5 por cento dos casos, o tempo médio entre o diagnóstico e a correção da fístula foi de 29,6 (7-63 meses) ocorreu um fechamento espontâneo após cinco meses de sondagem vesical de demora, a Uretrocistografia Retrograda e Miccional demonstrou a localização da fístula em 71,4 por cento. Nenhum paciente apresentou recidiva da fístula após correção pela técnica de York Mason modificada. A colostomia foi realizada em 50 por cento dos casos e não ocorreram casos de incontinência fecal ou estenose anal. CONCLUÇÃO: Após identificação de fístula reto-uretral, não é necessário à realização de colostomia e cistostomia de rotina.

ABSTRACT

OBJECTIVE: Current published data regarding the prognostic value of microvascular invasion (MVI) in patients with prostate cancer (PCa) have yielded mixed results. Furthermore, most important series had surgical procedures performed by multiple surgeons and surgical specimens analyzed by multiple pathologists. We determined the relation of MVI with other pathologic features and whether this finding can be used as an independent prognostic factor in patients with PCa. MATERIALS AND METHODS: We selected 428 patients with clinically localized PCa treated with radical prostatectomy (RP). MVI was correlated to other pathologic features. The Kaplan-Meier method was used to evaluate survival curves and statistical significance was determined by the log-rank test. Multivariate analysis was performed through a Cox proportional hazards regression model. RESULTS: Eleven percent out of the 428 patients presented MVI. Except for the lack of association with biopsy Gleason score, MVI was related to all clinical and pathologic features of RP specimens. Mean follow up after surgery was 53.9 ± 20.1 months. Patients with MVI presented a recurrence rate of 44.6 percent compared to only 20.2 percent for patients without MVI (Log-rank test - p < 0.001). After Cox regression analysis, MVI was an independent prognostic feature related to biochemical recurrence. CONCLUSIONS: MVI is associated to advanced pathologic features of PCa and is an important prognostic factor regarding disease recurrence in patients treated with RP. These findings support the recommendations to the routine evaluation of this variable in pathologic reports of RP specimens.

ABSTRACT

OBJECTIVES: The treatment of recurrent prostate cancer after radiotherapy or brachytherapy through radical prostatectomy has been little indicated due to the concern over the procedure's morbidity. We present the experience of our service with postradiotherapy radical prostatectomy. MATERIALS AND METHODS: Between 1996 and 2002, 9 patients submitted to radiotherapy due to prostate cancer were treated with salvage surgery for locally recurrent disease. All patients had a biopsy of the prostate confirming the tumor recurrence, increase in the PSA levels and staging without evidence of a systemic disease. We have assessed the morbidity and the recurrence-free survival rate after salvage radical prostatectomy. RESULTS: Preradiotherapy PSA varied from 6.2 to 50 ng/mL (mean 17.3) and clinical staging T1, T2 and T3 in 33.3%, 44.4% and 22.2% of the patients respectively. The interval for the biopsy after conforming external beam radiotherapy or brachytherapy varied from 8 to 108 months (median: 36). Four patients received antiandrogenic therapy neoadjuvant to the surgery with a mean of 7 months (1-48) after radiotherapy. From the six patients potent before the surgery, three have presented erectile dysfunction. Urinary incontinence as well as bladder neck sclerosis occurred in two patients (22.2%). Biochemical recurrence occurred in two individuals (22.2%) 12 months after the surgery. Biochemical recurrence-free survival rate was 77.8% with median follow-up time of 30 months (8-102). CONCLUSION: Salvage radical prostatectomy is a safe and effective alternative for the treatment of locally recurrent prostate cancer after radiotherapy and brachytherapy.

ABSTRACT

OBJECTIVE: To develop a preoperative nomogram to predict pathologic outcome in patients submitted to radical prostatectomy for clinical localized prostate cancer. MATERIALS AND METHODS: Nine hundred and sixty patients with clinical stage T1 and T2 prostate cancer were evaluated following radical prostatectomy, and 898 were included in the study. Following a multivariate analysis, nomograms were developed incorporating serum PSA, biopsy Gleason score, and percentage of positive biopsy cores in order to predict the risks of extraprostatic tumor extension, and seminal vesicle involvement. RESULTS: In univariate analysis there was a significant association between percentage of positive biopsy cores (p < 0.001), serum PSA (p = 0.001) and biopsy Gleason score (p < 0.001) with extraprostatic tumor extension. A similar pathologic outcome was seen among tumors with Gleason score 7, and Gleason score 8 to 10. In multivariate analysis, the 3 preoperative variables showed independent significance to predict tumor extension. This allowed the development of nomogram-1 (using Gleason scores in 3 categories - 2 to 6, 7 and 8 to 10) and nomogram-2 (using Gleason scores in 2 categories - 2 to 6 and 7 to 10) to predict disease extension based on these 3 parameters. In the validation analysis, 87% and 91.1% of the time the nomograms-1 and 2, correctly predicted the probability of a pathological stage to within 10% respectively. CONCLUSION: Incorporating percent of positive biopsy cores to a nomogram that includes preoperative serum PSA and biopsy Gleason score, can accurately predict the presence of extraprostatic disease extension in patients with clinical localized prostate cancer.
