Management of panurothelial disease in superficial bladder cancer.

BACKGROUND: A 59-year-old female presented with a history of recurrent superficial bladder cancer. Since the initial diagnosis 12 years earlier, she had had 12 recurrences, all treated with transurethral resection with adjuvant bacillus Calmette-Guérin and mitomycin C. Pathology samples had always shown Ta grade 1 transitional-cell carcinoma. At the last recurrence, she presented with several papillary lesions throughout the bladder, discovered on control cystoscopy. Transurethral resection revealed a papillary grade 3 transitional-cell carcinoma of the bladder. INVESTIGATIONS: Intravenous urography and ureteroscopy. DIAGNOSIS: Panurothelial superficial transitional-cell carcinoma. MANAGEMENT: Radical cystectomy with total right ureterectomy and distal left ureterectomy. Reconstruction of the urinary tract was performed with the distal ileum detubulized and rearranged in a U shape. A pyeloileal anastomosis and a proximal ureteroileal anastomosis were performed at the right and left sides respectively.

An improved technique for controlling bleeding during simple retropubic prostatectomy: a randomized controlled study.

OBJECTIVE: To compare two techniques of open prostatic adenectomy (OPA) for controlling bleeding, as OPA is the most effective surgical method for alleviating obstructive symptoms related to benign prostatic hyperplasia (BPH) but there is always a risk of peri-operative bleeding. PATIENTS AND METHODS: The study comprised a prospective and randomized analysis of 62 men with BPH who consecutively had OPA between January 2002 and September 2004. Two techniques were used: in group 1, patients had the Millin modified retropubic prostatectomy, and in group 2 they had a classical transvesical prostatectomy. Blood loss during and after surgery was analysed. RESULTS: The median (range) blood loss during surgery was 362 (50-700) and 640 (200-1500) mL for groups 1 and 2, respectively (P = 0.007). The mean (sd) decrease in haemoglobin level from before to 1 day after surgery was 1.76 (0.31) and 3.15 (0.33) g/dL for groups 1 and 2, respectively (P < 0.001). When comparing the first and third days after surgery, there were no further significant decreases in levels for group 1, at 0.15 (0.31) g/dL (P = 0.175), but there was a significant decrease for group 2, at 0.74 (0.33) g/dL (P = 0.031). There was a similar decrease in haematocrit levels. While three patients from group 2 required a blood transfusion, only one from group 1 had to be transfused. CONCLUSION: The Millin technique, as modified by one of the present authors, can significantly control bleeding during and after surgery, and reduce transfusion rates, when compared to the classic transvesical prostatectomy.

Urinary hyaluronan as a marker for the presence of residual transitional cell carcinoma of the urinary bladder.

OBJECTIVE: The purpose of this report is to evaluate the value of urinary hyaluronan (HA) as a maker of residual transitional cell carcinoma (TCC). PATIENTS AND METHODS: Urine samples were collected from 83 patients hospitalized for transurethral resection (TUR). Patient ages ranged from 36 to 86 years. Samples were taken both before and after surgery. HA analysis was performed using an "ELISA-like" fluorometric assay. RESULTS: Patients were divided into two groups: a control group whose previous diagnosis was negative for tumors (n=22) and another with positive diagnosis for tumors (n=61) which was further sub-divided into with and without residual tumor. After the second procedure 47 individuals did not display residual tumor, whereas 14 (23%) did. The average HA in the control group was 8.3 microg/L pre- and 7.1 post-operatively, hence, no change occurred (p=0.471). In the group with TCC patients, the HA dropped from 885.5 microg/L to 215.3 microg/L with residual tumors and from 234.3 microg/L to 11.2 microg/L for those without residual tumor. Using a cut-off value of 20 microg/L, the sensitivity to detect residual tumor is 92.9% and specificity is 83%. CONCLUSION: HA in addition to being one of the best markers for the initial evaluation of bladder carcinoma can be used to determine the presence of a residual tumor. This is associated with poor prognosis.

The percentage of positive biopsy cores as a predictor of disease recurrence in patients with prostate cancer treated with radical prostatectomy.

OBJECTIVE: To analyse the prognostic value of the percentage of positive biopsy cores (PPBC) in determining the pathological features and biochemical outcome of patients with prostate cancer treated by radical prostatectomy, as published data evaluating the prognostic value of PPBC in such patients have limitations. PATIENTS AND METHODS: A group of 534 patients with clinically localized prostate cancer was selected. The PPBC was defined as the number of positive biopsy cores/total number of biopsy cores x 100, and grouped into categories of <25%, 25.1-50%, 50.1-75% and 75.1-100%. Patients were divided in low-, intermediate- and high-risk groups according to the usual variables. RESULTS: The mean follow-up was 60.5 months. PPBC was associated with the preoperative serum prostate-specific antigen (PSA) level, biopsy Gleason score and clinical stage. On multivariate analysis, PPBC was a significant predictor of extraprostatic disease and seminal vesicle involvement. Of patients in the four PPBC categories, 16%, 27%, 33% and 60%, respectively, had biochemical recurrence (P < 0.001), and on Cox regression analysis, PPBC was an independent predictor of disease recurrence. After segregating patients into risk groups the PPBC further stratified patients using thresholds of 75% (P = 0.006), 25% (P = 0.026) and 50% (P = 0.011) for low-, intermediate- and high-risk groups, respectively. CONCLUSIONS: We confirmed, with a longer follow-up, the clinical utility of the PPBC in determining the pathological features and biochemical outcome of patients with prostate cancer treated with radical prostatectomy, and established thresholds for use in patients in the three risk groups.

Analysis of risk factors of involvement of seminal vesicles in patients with prostate cancer undergoing radical prostatectomy.

OBJECTIVE: To determine through preoperative serum PSA level, Gleason score on biopsy and percentage of fragments affected by tumor on biopsy, the probability of involvement of the seminal vesicles. MATERIALS AND METHODS: During the period between March 1991 to December 2002, we selected 899 patients undergoing radical prostatectomy for treatment of localized prostate adenocarcinoma. The analyzed preoperative variables were PSA, percentage of positive fragments and Gleason score on the biopsy. Pre-operative PSA was divided in scales from 0 to 4.0 ng/mL, 4.1 to 10 ng/mL, 10.1 to 20 ng/mL and > 20 ng/mL, Gleason score was categorized in scales from 2 to 6. 7 and 8 to 10, and the percentage of affected fragments was divided in 0 to 25%, 25.1% to 50%, 50.1% to 75%, and 75.1% to 100%. All these variables were correlated with the involvement of seminal vesicles in the surgical specimen. RESULTS: Of the 899 patients under study, approximately 11% (95% CI, [9% - 13%]) had involvement of seminal vesicles. On the multivariate analysis, when PSA was < or = 4, the Gleason score was 2 to 6, and less than 25% of fragments were involved on the biopsy, only 3.6%, 7.6% and 6.2% of patients respectively, had involvement of seminal vesicles. On the multivariate analysis, we observed that PSA, Gleason score and the percentage of involved fragments were independent prognostic factors for invasion of seminal vesicles. CONCLUSION: The preoperative variables used in the present study allow the identification of men with minimal risk (lower than 5%) if involvement of seminal vesicles.

Sarcomatoid differentiation in renal cell carcinoma: prognostic implications.

INTRODUCTION: Renal cell carcinoma with sarcomatoid differentiation is a tumor with aggressive behavior that is poorly responsive to immunotherapy. The objective of this study is to report our experience in the treatment of 15 patients with this tumor. MATERIALS AND METHODS: We retrospectively analyzed 15 consecutive cases of renal cell carcinoma with sarcomatoid differentiation diagnosed between 1991 and 2003. The clinical presentation and the pathological stage were assessed, as were the tumor's pathological features, use of adjuvant immunotherapy and survival. The study's primary end-point was to assess survival of these individuals. RESULTS: The sample included 8 women and 7 men with mean age of 63 years (44-80); follow-up ranged from 1 to 100 months (mean 34). Upon presentation, 87% were symptomatic and 4 individuals had metastatic disease. Mean tumor size was 9.5 cm (4-24) with the following pathological stages: 7% pT1, 7% pT2, 33% pT3, and 53% pT4. The pathological features showed high-grade tumors with tumoral necrosis in 87% of the lesions and 80% of intratumoral microvascular invasion. Disease-free and cancer-specific survival rates were 40 and 46% respectively, with 2 cases responding to adjuvant immunotherapy. CONCLUSIONS: Patients with sarcomatoid tumors of the kidney have a low life expectancy, and sometimes surgical resection associated with immunotherapy can lead to a long-lasting therapeutic response.

Prognostic value of the percentage of positive fragments in biopsies from patients with localized prostate cancer.

OBJECTIVE: To assess the prognostic value of the percentage of positive fragments (PPF) in biopsies from patients with localized prostate cancer (PCa) undergoing radical prostatectomy. MATERIALS AND METHODS: During the period from March 1991 to November 2000, 440 patients were selected. Cases receiving neoadjuvant or adjuvant hormone therapy, or adjuvant radiotherapy, were excluded, as were cases presenting Gleason scores higher than 6 at biopsy. PPF was defined as the total number of fragments divided by the total number of biopsy fragments times 100. This variable was initially divided into categories from 0 to 25%, 25.1% to 50%, 50.1 to 75% and 75% to 100%. During the postoperative period, patients were assessed every 2 months for 1 year, then every 6 months for 5 years, and then yearly. Biochemical recurrence was defined as serum PSA higher than or equal to 0.4 ng/mL. Median follow-up was 60 months. RESULTS: One hundred and nine (24.8%) of the 440 patients under study had biochemical recurrence. In the univariate analysis, PPF significantly influenced disease-free survival (log-rank, p < 0.001), and patients with PPF between 75 and 100% presented a risk of a biochemical recurrence of the disease 3 times higher than patients with PPF between 0 and 25% (p < 0.001). After the Cox regression analysis, both serum PSA (p = 0.001) and PPF (p < 0.001) showed to be independent predictive factors for disease-free survival following surgery. CONCLUSION: PPF measurement in biopsy is a simple and practical method, which should be routinely used as a predictive factor for biochemical recurrence in patients with PCa presenting Gleason scores between 2 and 6.

Pathological extension of prostate cancer as defined by Gleason score on biopsy.

INTRODUCTION: Based on the importance of the Gleason score on the behavior of prostate adenocarcinoma, this study attempts to predict the extension of prostate adenocarcinoma pre-operatively, as defined by the Gleason score on biopsy, in individuals who will undergo radical prostatectomy. MATERIALS AND METHODS: We selected 899 individuals who underwent retropubic radical prostatectomy from 1988 to 2004. Clinical and pathological data obtained in the preoperative period were retrospectively analyzed through digital rectal examinations of the prostate, initial serum PSA levels and pathological data provided by biopsy. The Gleason score on biopsy was assessed and divided into 3 groups: 2 to 6, 7, and 8 to 10, and correlated with the possibility of the disease being confined to the prostate. RESULTS: From the 899 selected patients, 654 (74%) showed Gleason scores of 2 to 6, 165 (18%) had a score of 7 and 80 (9%) had scores of 8 to 10 on biopsy. The likelihood of confined diseases, extraprostatic extensions, invasion of seminal vesicles and lymph nodal involvement were respectively: 74%, 18%, 8% and 0.8% for a Gleason score of 2 to 6, 47%, 30%, 19% and 4% for a Gleason score of 7, and 49%, 29%, 18% and 4% for a Gleason score of 8 to 10. CONCLUSION: In patients who will undergo radical prostatectomy due to prostate adenocarcinoma, a Gleason score of 7 on biopsy shows the same behavior as a Gleason score of 8 to 10 in relation to extension of disease.

Prostate biopsy: is age important for determining the pathological features in prostate cancer?

INTRODUCTION: The influence of age on the aggressiveness of prostate cancer (PCa) is controversial. This study aims to assess the influence of age in determining the pathological features of biopsies from patients diagnosed with PCa. PATIENTS AND METHODS: We selected 1422 patients with clinical suspicion of PCa; among them, 547 (38.5%) had received a diagnosis of adenocarcinoma. Patients were categorized into the following age groups: up to 50 years old, 51 to 60 years, 61 to 70 years, 71 to 80 years, and over 80 years. The evaluated variables were histological grade, presence of perineural invasion and estimate of tumor volume through measurement of the maximum percentage of tissue with cancer in one fragment and total percentage of tissue with cancer in the sample. RESULTS: The mean age of patients was 66.4 years, with age range from 32 to 94 years. The estimate of tumor volume by maximum percentage of tissue with cancer in one fragment (p = 0.064), total percentage of tissue with cancer in the sample (p = 0.443), and Gleason score (p = 0.485) were not statistically different in relation to the age groups under study. The presence of perineural invasion occurred more frequently among the 50 years and 81 years age groups when compared with patients aged from 51 to 60 and from 61 to 80 years (p = 0.005). CONCLUSIONS: Age did not represent a determining factor for pathological findings concerning Gleason score and estimate of tumor volume by the variables in use.

Serum PSA and cure perspective for prostate cancer in males with nonpalpable tumor.

INTRODUCTION: Many studies have shown the association between PSA levels and the subsequent detection of prostate cancer. In the present trial, we have studied the relationship between preoperative PSA levels and clinical outcome following radical prostatectomy in men with clinical stage T1c. MATERIALS AND METHODS: 257 individuals with clinical stage T1c undergoing retropubic radical prostatectomy were selected in the period from 1991 to 2000. Following surgery, biochemical recurrence-free survival curves were constructed according to PSA levels between 0-4; 4.1-10; 10.1-20 and > 20 ng/mL. RESULTS: Of the total of 257 selected patients, 206 (80%) had Gleason scores from 2 to 6 and 51 (20%), presented Gleason scores 7 and 8, as defined by the pathological report from prostate biopsy. There was no biochemical recurrence of disease when the PSA was lower than 4, regardless of Gleason score. Biochemical recurrence-free survival according to PSA between 0-4; 4.1-10; 10.1-20 and > 20 was 100%, 87.6%, 79% and 68.8% for Gleason scores 2-6 and 100%; 79.4%; 40% and 100% for Gleason scores 7-8 respectively. When all individuals were grouped, regardless of their Gleason scores, the probability of biochemical recurrence-free survival was 100%, 65.1%, 53.4% and 72.2% according to PSA between 0-4; 4.1-10; 10.1-20 and > 20 ng/mL respectively. CONCLUSION: Non-palpable prostate cancer presents higher chances of cure when the PSA is inferior to 4 ng/mL.

Prediction of pathological stage in prostate cancer through the percentage of involved fragments upon biopsy.

INTRODUCTION: The need for defining the extension of disease in patients undergoing radical prostatectomy due to prostate adenocarcinoma is a relevant factor cure in such individuals. In order to identify a new independent preoperative factor for predicting the extension of prostate cancer, we assessed the role of the percentage of positive fragments upon biopsy. MATERIALS AND METHODS: A retrospective study compared the percentage of positive fragments on biopsy with the extension of disease as defined by the pathological examination of the surgical specimen from 898 patients undergoing radical prostatectomy due to clinically localized prostate cancer. RESULTS: On the univariate analysis, the percentage of positive fragments on biopsy showed a statistical significance for predicting confined disease (p < 0.001), which was found in 66.7% of the cases under study. Additionally, we observed that the total number of removed fragments exerts no influence on the extension of the disease (p = 0.567). CONCLUSION: the percentage of positive fragments is an independent factor for predicting the pathological stage of prostate adenocarcinoma, and the number of removed fragments is not related to the extension of the disease.

Analysis of prognostic factors in patients with transitional cell carcinoma of the bladder treated with radical cystectomy.

OBJECTIVE: To analyze the results of the treatment of transitional cell carcinoma (TCC) of the bladder with radical cystectomy and determine which prognostic factors can be utilized as disease-free survival and cancer-specific survival independent variables. MATERIALS AND METHODS: Medical records of 113 patients submitted to radical cystectomy and bilateral iliac lymphadenectomy between 1993 and 2005 were reviewed. The risk factors analyzed were age, sex, pathological stage, tumor grade, presence of carcinoma in situ and the presence of lymph nodes involvement. RESULTS: After a mean follow-up of 31.7 +/- 28.5 months, 46 patients (40.7%) presented recurrence and 24 patients (21.2%) died due to cancer. Only pathological stage and the lymph nodes involvement became independent variables for recurrence and survival. Patients with T4 stage presented 9.6 times the risk of recurrence of the disease when compared with stage T0 patients (p = 0.010) and the patients with lymph node involvement presented 2.5 times the risk of recurrence (p = 0.047) and 3.1 times the risk of death (p = 0.022) when compared to patients without lymph nodes involvement. CONCLUSIONS: Pathological stage and the involvement of lymph nodes represented more important prognostic variables, and in the presence of advanced stage tumors (T3/T4) and involvement of lymph nodes, the institution of adjuvant treatment should be considered.

Age impact in clinicopathologic presentation and the clinical evolution of prostate cancer in patients submitted to radical prostatectomy.

OBJECTIVE: To assess the influence of age in pathological findings and clinical evolution of prostate cancer in patients treated with radical prostatectomy. MATERIALS AND METHODS: Five hundred and fifty-six patients operated on between 1991 and 2000 were selected. Patients were divided into age groups of between 10 and 49 years, 50 to 59 years, 60 to 69 years and 70 to 83 years. RESULTS: Patients having less than 60 years of age presented clinical stage (p = 0.001), PSA (p = 0.013) and biopsy Gleason score (p = 0.013) more favorable than older patients. Age groups did not show any relationship between either postoperative Gleason score or pathological stage or risk of non-confined organ disease and involvement of seminal vesicles. After a mean follow-up of 58.3 months, 149 (27%) patients presented recurrence. Patients aged between 40 and 59 years presented a disease-free survival rate significantly higher when compared to patients aged between 60 and 83 years (p = 0.022). However, when controlled with clinical stage, PSA, Gleason score and percentage of positive fragments, there was no relationship between age and biochemical recurrence risk (p = 0.426). CONCLUSIONS: Even though younger patients presented more favorable preoperative characteristics, postoperative pathological findings and biochemical recurrence rates did not differ between studied age groups.

A new nomogram to predict pathologic outcome following radical prostatectomy.

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.

Renal lymphoma. Atypical presentation of a renal tumor.

Primary renal lymphoma is a rare lesion that represents less than 1% of the kidney's lesions. The authors discuss the case of a 67-year-old woman with a renal mass identified 7 years after treatment of a non-Hodgkin's lymphoma, and analyze clinical and prognostic aspects of renal lymphomas. Radiological findings in this case showed an uncommon presentation of the renal lymphomatous lesion which served as a warning that tumors might appear during follow-up as atypical and uncommon lesions.

Salvage radical prostatectomy: an alternative treatment for local recurrence of radioresistant cancer.

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.

Microvascular invasion is an independent prognostic factor in patients with prostate cancer treated with radical prostatectomy.

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% compared to only 20.2% 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.

Complications in radical cystectomy performed at a teaching hospital.

OBJECTIVES: Radical cystectomy with urinary diversion has been the standard treatment to infiltrative bladder neoplasms. We have analyzed a series of radical cystectomies performed by residents at a school hospital and compared the rates of complications in this series with those reported in literature. MATERIALS AND METHODS: During the period of December 1996 to December 2000, 59 surgeries were performed by 8 residents in our department, always oversaw by the same assistant. We have analyzed age, gender, pathological staging, type of diversion used, surgical time, need for blood transfusion and blood volume used during surgery, immediate complications (1 to 30 days), late complications, and follow-up time. RESULTS: There were 51 men and 8 women. Mean age was 61.3 years (28 to 89), and the majority of the group was over 60 years (60%). Mean follow-up time was 8.5 months (3 to 36). Camey II ileal neobladder was used in 36 (62%) cases, ureterosigmoidostomy in 8 (13.8%), Bricker in 12 (20.7%), and Mainz-Pouch II diversion in 2 (3.5%) cases. Blood transfusion was required in 25 (42%) cases. Immediate complications were observed in 19% of the patients, and late complications in 19% as well. CONCLUSION: When oversaw by an experienced surgeon, a resident gathers the conditions to perform a radical cystectomy, without significant increase in complication rates.
