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

International braz j urol (2005)

Alberto A. Antunes Kátia Ramos Moreira Leite Marcos F. Dall’Oglio Alexandre Crippa Luciano Nesrallah

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.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.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).Age did not represent a determining factor for pathological findings concerning Gleason score and estimate of tumor volume by the variables in use.

MMP-9 Overexpression Due to TIMP-1 and RECK Underexpression is Associated with Prognosis in Prostate Cancer

The International Journal of Biological Markers (2011)

Sabrina T. Reis José Pontes‐Júnior Alberto A. Antunes Juliana M. Sousa-Canavez Marcos F. Dall’Oglio

Background Extracellular matrix homeostasis is strictly maintained by a coordinated balance between the expression of metalloproteinases (MMPs) and their inhibitors. The purpose of this study was to investigate whether the expression of MMP-9 and its specific inhibitors, TIMP-1 and RECK, are expressed in a reproducible, specific pattern and if the profiles are related to prognosis and clinical outcome in prostate cancer (PC). Methods MMP-9, TIMP-1, and RECK expression levels were analyzed by quantitative real-time polymerase chain reaction (qRT-PCR) in fresh-frozen malignant tissue specimens collected from 79 patients with clinically localized PC submitted to radical prostatectomy (RP). Frozen benign prostatic tissue from another 10 men with prostate cancer, also submitted to RP, was analyzed to determine if the profile of gene expression was maintained. The control group consisted of 11 patients with benign prostate hyperplasia (BPH). Results In the tumor samples, MMP-9 was overexpressed by 9.2 times, and TIMP-1 and RECK were underexpressed (0.75 and 0.80 times, respectively). Overexpression of MMP-9 was significantly related to PSA levels above 10 ng/mL (p=0.033). In addition, MMP-9 overexpression was related to biochemical recurrence, with a marginal statistical significance (p=0.089). MMP-9 was also overexpressed in benign tissues of patients with PC, as were TIMP-1 and RECK, in contrast to their underexpression in tumor samples. Conclusion Our results show that MMP-9 is overexpressed and its negative regulators are underexpressed in PC tissue, emphasizing a possible role of MMP-9 in the carcinogenesis process. Additionally, we noticed a relationship between MMP-9 overexpression and increased levels of PSA, an important prognostic factor. In benign tissue adjacent to tumors, the MMP-9 equilibrium is likely maintained because the expression of its negative regulators is preserved.

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

International braz j urol (2005)

Marcos F. Dall’Oglio Alexandre Crippa Luís C. Oliveira João F. Neves Neto Kátia Ramos Moreira Leite

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.

Perineural invasion by transitional cell carcinoma of the bladder in patients submitted to radical cystectomy: what is the prognostic value?

International braz j urol (2007)

Alberto A. Antunes Luciano Nesrallah Marcos F. Dall’Oglio Alexandre Crippa Adriano Nesrallah

Determine the prognostic value of perineural invasion (PNI) in patients with transitional cell carcinoma (TCC) of the bladder treated with radical cystectomy.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.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.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.

Undergrading and understaging in patients with clinically insignificant prostate cancer who underwent radical prostatectomy

International braz j urol (2010)

Irai S. Oliveira José Pontes‐Júnior Daniel Kanda Abe Alexandre Crippa Marcos F. Dall’Oglio

PURPOSE: The aim of our study is to evaluate the undergrading and understaging rates in patients with clinically localized insignificant prostate cancer who underwent radical prostatectomy. MATERIALS AND METHODS: Between July 2005 and July 2008, 406 patients underwent radical prostatectomy for clinical localized prostate cancer in our hospital. Based on preoperative data, 93 of these patients fulfilled our criteria of non-significance: Gleason score < 7, stage T1c, PSA < 10 ng/mL and percentage of affected fragments less than 25%. The pathologic stage and Gleason score were compared to preoperative data to evaluate the rate of understaging and undergrading. The biochemical recurrence free survival of these operated insignificant cancers were also evaluated. RESULTS: On surgical specimen analysis 74.7% of patients had Gleason score of 6 or less and 25.3% had Gleason 7 or greater. Furthermore 8.3% of cases showed extracapsular extension. After 36 months of follow-up 3.4% had biochemical recurrence, defined by a PSA above 0.4 ng/mL. CONCLUSIONS: Despite the limited number of cases, we have found considerable rates of undergrading and understaging in patients with prostate cancer whose current definitions classified them as candidates for active surveillance. According to our results the current definition seems inadequate as up to a third of patients had higher grade or cancer outside the prostate.

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

BJU International (2005)

Alberto A. Antunes Miguel Srougi Marcos F. Dall’Oglio Alexandre Crippa João Carlos Campagnari

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.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.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.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.

Predicting outcomes in partial nephrectomy: is the renal score useful?

International braz j urol (2017)

André Costa Matos Marcos F. Dall’Oglio José R. Colombo Alexandre Crippa João Alexandre Queiroz Juveniz

Introduction and Objective The R.E.N.A.L. nephrometry system (RNS) has been validated in multiple open, laparoscopic and robotic partial nephrectomy series. The aim of this study was to test the accuracy of R.E.N.A.L. nephrometry system in predicting perioperative outcomes in surgical treatment of kidney tumors <7.0cm in a prospective model. Materials and Methods Seventy-one patients were selected and included in this prospective study. We evaluate the accuracy of RNS in predicting perioperative outcomes (WIT, OT, EBL, LOS, conversion, complications and surgical margins) in partial nephrectomy using ROC curves, univariate and multivariate analyses. R.E.N.A.L. was divided in 3 groups: low complexity (LC), medium complexity (MC) and high complexity (HC). Results No patients in LC group had WIT >20 min, versus 41.4% and 64.3% MC and HC groups respectively (p=0.03); AUC=0.643 (p=0.07). RNS was associated with convertion rate (LC:28.6% ; MC:47.6%; HC:77.3%, p=0.02). Patients with RNS <8 were most often subjected to partial nephrectomy (93% x 72%, p=0.03) and laparoscopic partial nephrectomy (56.8% x 28%, p=0.02), AUC=0.715 (p=0.002). The RNS was also associated with operative time. Patients with a score >8 had 6.06 times greater chance of having a surgery duration >180 min. (p=0.017), AUC=0.63 (p=0.059). R.E.N.A.L. score did not correlate with EBL, complications (Clavien >3), LOS or positive surgical margin. Conclusion R.E.N.A.L. score was a good method in predicting surgical access route and type of nephrectomy. Also was associated with OT and WIT, but with weak accuracy. Although, RNS was not associated with Clavien >3, EBL, LOS or positive surgical margin.

Survival of patients with prostate cancer and normal PSA levels treated by radical prostatectomy

International braz j urol (2005)

Marcos F. Dall’Oglio Alexandre Crippa Alberto A. Antunes Luciano Nesrallah Kátia Ramos Moreira Leite

INTRODUCTION: The unpredictability of prostate cancer has become a daily challenge for the urologist, with different strategies being required to manage these cases. In this study, we report on the perspectives for curing prostate cancer in males undergoing radical prostatectomy with Gleason score of 2-6 on prostate biopsy in relation to pre-operative PSA levels. MATERIALS AND METHODS: From 1991 - 2000, we selected 440 individuals whose pathological diagnosis revealed a Gleason score of 2-6 upon prostate biopsy and who subsequently underwent retro-pubic radical prostatectomy due to localized prostate cancer. The clinical stage identified in the group under study was T1c: 206 (46.8%); T2a: 122 (27.7%); T2b: 93 (21.1%); T2c: 17 (3.9%); T3a: 2 (0.5%). Following surgery, we constructed a biochemical recurrence-free survival curve according to pre-operative PSA levels between 0-4; 4.1-10; 10.1-20 and > 20 ng/mL, with a median follow-up of 5 years. RESULTS: Following radical prostatectomy, the pathological stage was confirmed as pT2a: 137 (31.1%); T2b: 118 (26.8%); T2c: 85 (19.3%); T3a: 67 (15.2%); T3b: 6 (1.4%); T3c: 22 (5%). The biochemical recurrence-free survival, according to PSA values between 0-4; 4.1-10; 10.1-20 and > 20 ng/mL, was 86.6%, 62.7%, 39.8% and 24.8% respectively. CONCLUSION: Better chances for curing low-grade prostate cancer occur in individuals with normal PSA for whom a biopsy is not usually recommended.

Radical Retropubic Prostatectomy on Outpatient Basis

Journal of cancer research updates (2014)

Bruno Costa do Prado Cláudia Marquez Simões Flávio Guilherme Moreira Arêas Alexandre Crippa Marcos F. Dall’Oglio

Introduction: This study evaluated the possibility of performing in our midst the open radical prostatectomy with discharge on the same day of the procedure, aiming the improvement of postoperative recovery and reduce hospital costs without loss of quality of care, or decreased patient satisfaction with treatment. Patients and Methods: We selected 27 patients with localized prostate cancer during the period from April 2011 to January 2012, which had a low surgical risk and opted for the open radical prostatectomy. We evaluated the feasibility of outpatient open radical prostatectomy, perioperative complications, and patient satisfaction with treatment. Results: Eleven (40.7%) patients were discharged on the same day of the procedure; thirteen were discharged in the morning after surgery and three in the second postoperative day. All patients underwent general anesthesia. The use of opioids in safe doses for epidural anesthesia was administered in 13 patients, improving pain control and enabling early discharge in 8 (61.5%) patients. Only 3 (21.4%) patients who did not receive epidural opioid achieved discharge on the same day of surgery (p = 0.04). No patient had a major complication or was readmitted to the hospital. There was no difference in patient satisfaction with treatment between the group of the same day surgery and the patients with longer hospitalization. Conclusion: The open radical prostatectomy can be performed with safety on an outpatient basis, in properly selected patients, with no decrease in patient satisfaction with treatment.

Anatrophic nephrotomy as nephron-sparing approach for complete removal of intraparenchymal renal tumors

International braz j urol (2012)

Marcos F. Dall’Oglio Lucas Ballarotti Carlo C. Passerotti Davi V. Paluello José R. Colombo

OBJECTIVE: Partial nephrectomy for small kidney tumors has increased in the last decades, and the approach to non-palpable endophytic tumors became a challenge, with larger chances of positive margins or complications. The aim of this study is to describe an alternative nephron-sparing approach for small endophytic kidney tumors through anatrophic nephrotomy. PATIENTS AND METHODS: A retrospective analysis of patients undergoing partial nephrectomy at our institution was performed and the subjects with endophytic tumors treated with anatrophic nephrotomy were identified. Patient demographics, perioperative outcomes and oncological results were evaluated. RESULTS: Among the partial nephrectomies performed for intraparenchymal tumors between 06/2006 and 06/2010, ten patients were submitted to anatrophic nephrotomy. The mean patient age was 42 yrs, and the mean tumor size was 2.3 cm. Mean warm ischemia time was 22.4 min and the histopathological analysis showed 80% of clear cell carcinomas. At a mean follow-up of 36 months, no significant creatinine changes or local or systemic recurrences were observed. CONCLUSION: The operative technique described is a safe and effective nephron-sparing option for complete removal of endophytic renal tumors.
