Penile Cancer Mortality in Brazil: Are We Making Progress?

PURPOSE: This study aims to analyze the trends in mortality rates from penile cancer (PeC) and the treatment modalities adopted in Brazil over recent years. MATERIALS AND METHODS: Death records for PeC cases (International Classification of Diseases, version 10 C60) and treatment modalities were extracted from the DATASUS database. A joinpoint regression analysis was conducted to examine the data. RESULTS: A total of 7,848 deaths due to PeC were recorded in Brazil between 1996 and 2020. Increasing mortality trends were observed, with an average annual percentage change (AAPC) of 0.91 (0.6-1.2; P < .001). The North and Northeast regions had the highest age-standardized mortality rates (ASMRs) and AAPCs. From 2008 to 2020, the ASMR in the Northeast region remained stable, whereas the North region surpassed it. The Southeast region exhibited a significant downward trend, with an AAPC of -0.91 (-1.3 to -0.5; P < .001). Penile biopsies declined and were more frequent in the southeastern region. A total of 8,498 penile amputations were performed, with 39.4% and 29.1% conducted in the Southeast and Northeast regions, respectively. CONCLUSION: Brazil has experienced increasing mortality trends in PeC over the past 2 decades. Low schooling, married, and young men from the North or Northeast regions represent the majority of deaths. Urgent efforts are needed to enhance the diagnosis and treatment of PeC to prevent and reduce mortality rates in the country.

Epidemiological profile of COVID-19 in patients with prostate cancer undergoing androgen deprivation therapy at a Brazilian Cancer Center.

Older individuals with cancer constitute a high-risk group for COVID-19. Entry of the virus into cells occurs through the binding of the S protein with angiotensin-converting enzyme 2, which is mediated by the TMPRSS2 gene and regulated by androgen receptors. Androgen deprivation therapy in patients with prostate cancer inhibits AR-TMPRSS2 interactions, which in turn inhibits the aggressiveness of the infection. We were unable to prove an association between the use of androgen deprivation therapy and a reduction in factors associated with worse clinical outcomes. Most of the data presented show a tendency to favor the outcomes of patients who do not undergo androgen deprivation therapy, which can be explained by the fact that, in general, their clinical conditions are better and their performance status scores are lower than those of patients who undergo androgen deprivation therapy. Abstract presented to the oncology department of A.C.Camargo Cancer Center as a conclusion of the Scientific Initiation. OBJECTIVE: To describe the epidemiological aspects of COVID-19 in patients with prostate cancer who received androgen deprivation therapy and those who did not. METHODS: We retrospectively analyzed the medical records of patients with prostate cancer undergoing androgen deprivation therapy and those who did not undergo androgen deprivation therapy. These patients were treated at the A.C.Camargo Cancer Center between March 2020 and March 2021. RESULTS: Of the 78 patients with prostate cancer and positive RT-PCR test results, 50% were undergoing androgen deprivation therapy, and 49% were experiencing a non-metastatic biochemical relapse. Of these, 80.6% were symptomatic on the day of examination compared to 97.2% in the Control Group. A total of 82.1% of the patients receiving androgen deprivation therapy required hospitalization, with 30.8% admitted to the intensive care unit compared to 21.6% in the Control Group. There was no statistically significant difference in the use of a high-flow oxygen cannula, the need for orotracheal intubation and mechanical ventilation, the need for dialysis, multiple organ failure, or death. A significant difference was found between the groups in terms of the average length of stay in the intensive care unit. CONCLUSION: Androgen deprivation therapy was not associated with protective factors or potential treatments in patients with prostate cancer and COVID-19. Although the number of patients analyzed was limited, and there may have been a selection bias, this is a unique study that cannot be expanded or replicated in similar (unvaccinated) populations.

Ergonomic risk assessment of surgeon's position during radical prostatectomy: Laparoscopic versus robotic approach.

BACKGROUND AND OBJECTIVES: Radical prostatectomy (RP) is a definitive surgical therapy for localized prostate cancer. Evidence suggests that the poor ergonomics of surgeons during RP may lead to work-related musculoskeletal disorders and loss of productivity. Since each surgery modality has its physical demands, we compared the ergonomic risk between laparoscopic (LRP) and robotic-assisted (RARP) radical prostatectomy. METHODS: The study assessed the posture of 10 urological surgeons during LRP and RARP surgeries with the Rapid Entire Body Assessment (REBA) scale. RESULTS: We found that the RARP approach resulted in lower REBA scores over the LRP procedure. CONCLUSIONS: Robotic surgery improves body posture for the urological surgeon like in other medical specialties. However, the surgeons display harmful postures in both surgeries.

Prognostic role of the immunohistochemical expression of proteins related to the renin-angiotensin system pathway in nonmetastatic clear cell renal cell carcinoma.

INTRODUCTION: Stage migration has been observed in renal cell carcinoma (RCC) in recent decades; however, mortality rates have continuously increased in some countries. Tumoral factors have been characterized as major predictors of RCC. Nonetheless, this concept can be improved by combining these tumoral factors with other variables, including biomolecular factors. PURPOSE: This study aimed to assess the immunohistochemical (IHC) expression and prognostic value of renin (REN), erythropoietin (EPO), and cathepsin D (CTSD), and to evaluate whether the concomitant expression of these markers can influence the prognostic outcomes in patients without metastasis. MATERIAL AND METHODS: In total, 729 patients with clear cell RCC (ccRCC) who underwent surgical treatment between 1985 and 2016 were evaluated. All the cases in the tumor bank were reviewed by dedicated uropathologists. The IHC expression patterns of the markers were assessed using a tissue microarray. REN and EPO were classified as "positive" or "negative" expression. CTSD was grouped into "absent or weak expression" or "strong expression." Associations between clinical and pathological variables and the studied markers, in addition to 10-year overall survival (OS), cancer-specific survival (CSS), and recurrence-free survival rates, were described. RESULTS: REN and EPO expressions were positive in 70.6% and 86.6% of patients, respectively. Absent or weak and strong expressions of CTSD were observed in 58.2% and 41.3% of the patients, respectively. EPO expression had no impact on survival rates even when assessed concomitantly with REN. Negative REN expression was associated with advanced age, preoperative anemia, larger tumors, perirenal fat, hilum or renal sinus infiltration, microvascular invasion, necrosis, high nuclear grade, and clinical stages III to IV. In contrast, strong CTSD expression was associated with poor prognostic variables. The expression patterns of REN and CTSD were unfavorable predictors of the 10-year OS and CSS. In particular, the combination of negative REN and strong CTSD expression had a negative impact on these rates, including a higher risk of recurrence. CONCLUSION: Loss of REN expression and strong CTSD expression were independent prognostic factors in nonmetastatic ccRCC, particularly when the concomitant expression pattern of both markers was present. EPO expression did not influence survival rates in this study.

Role of the Renin-Angiotensin System Components in Renal Cell Carcinoma: A Literature Review.

PURPOSE OF REVIEW: The physiological aspects of renin-angiotensin system (RAS) components are described in this review. Additionally, we present the main results of studies that could indicate an association between alterations in these components and cancer, particularly renal cell carcinoma (RCC). RECENT FINDINGS: The RAS undergoes a series of homeostatic and modulatory processes that extend to hypertrophy, hyperplasia, fibrosis, and remodeling, as well as angiogenesis, pro-inflammatory responses, cell differentiation, stem cell programming, and hematopoiesis. The link between cancer-related inflammation and RAS signaling converge in the response to tumor hypoxia and oxidative stress mechanisms, particularly with the angiotensin type 1 receptor leading to activation of transcription factors such as nuclear factor κB (NF-κB), as well as members of the signal transducer and activation of transcription (STAT) family and HIF1⍺. Dysregulation of the physiological actions of RAS in the microenvironment of inflammation and angiogenesis promotes tumor cell growth.

Sex with animals among men attended in referral centers for sexually transmitted infections in northeast Brazil: prevalence, associated factors and behavioral aspects

ABSTRACT Purpose Our objective was to investigate the prevalence of SWA, associated factors, relationship with STIs, and behavioral aspects in men attended at Referral Centers for STIs and acquired immunodeficiency syndrome (AIDS)/CR-STI/AIDS in northeast Brazil. Materials and Methods In this cross-sectional study, a questionnaire with sociodemographic, clinical, sexual and SWA practices information was applied to 400 men attended at two CR-STI/AIDS in Northeast Brazil on the years of 2018 and 2019. Clinical and laboratory diagnoses of STIs were confirmed in medical records. Logistic regression models were performed to identify the independent predictors for SWA. Results The prevalence of SWA over total samples was 15.00%. Of the participants, 239 (59.75%) of the participants were diagnosed with STIs, and of these 37 (15.48%) reported SWA. Most men practiced SWA in adolescence, being the last episode more than 20 years ago, usually with asinine and mules, in vaginal route and without a condom. SWA practitioners have higher percentages of occurrence of some viral STIs. SWA was associated with increasing age, history of residence in a rural area with remained over 12 years, married or widowed/separated, heterosexuals, with less than 7 years of study, Catholics, with hepatitis B, former user of alcoholic beverages and smokers, with a history of STI and intercourse with sex workers. Conclusion SWA practices increase STIs vulnerability. The association between hepatitis B and SWA highlights the importance of educational campaigns and conclusive studies on the topic.

Primary laparoscopic RPLND for pure seminona metastasis: feasibility of supine and lateral approaches

ABSTRACT Introduction Retroperitoneal lymphadenectomy (RPLND) is well established as a primary treatment, especially for high-risk stage I and stage IIA/B nonseminomatous tumors, but its value in seminomatous tumors is underreported (1). Classically, seminomas with isolated retroperitoneal lymphadenopathy are treated with external beam radiation therapy or systemic chemotherapy. Although these modalities are effective, they are associated with significant long-term morbidity (2, 3). Some retrospective studies have demonstrated the potential of RPLND as a first-line treatment for stage IIa seminoma, and two very recent prospective trials, still with interim results: SEMS TRIAL and PRIMETEST(3-7). The RPLND robotic technique has been previously described in the post-chemotherapy scenario, however, surgical videos of primary laparoscopic approach are lacking, especially in seminomatous disease (8). Materials and Methods We present two cases of primary videolaparoscopic RPLND, using different approaches.Case 1: Thirty four years-old, with prior right orchiectomy for mixed tumor. After 8 months he presented an two cm enlarged interaortocaval lymph node. Percutaneous biopsy showed pure seminoma metastasis.Case 2: Thirty three years-old, with previous left orchiectomy for stage I pure seminoma, without risk factors. After nine months, the patient had a three cm enlarged para-aortic lymph node. Results The surgical time ranged from 150 to 210 minutes, with a maximum bleeding of 300 mL and hospital discharge in 48 hours. In one of the cases, we identified a significant desmoplastic reaction, with firm adhesions to the great vessels, requiring vascular sutures, however, no major complication occurred. Pathological anatomy confirmed pure seminoma lymph node metastases in both cases. Conclusion Laparoscopic primary RPLND proved to be technically feasible, with less postoperative pain and early hospital discharge. We understand that more studies should be performed to confirm our oncological results.

Should obesity be associated with worse urinary continence outcomes after robotic-assisted radical prostatectomy? a propensity score matching analysis

ABSTRACT Purpose: To analyze the association between obesity and urinary incontinence rate in men submitted to robot-assisted radical prostatectomy (RARP) in a high-volume cancer center. Materials and Methods: We reported 1.077 men who underwent RARP as the primary treatment for localized prostate cancer from 2013 to 2017. Patients were classified as non-obese (normal BMI or overweight) or obese men (BMI ≥30kg/m2). They were grouped according to the age, PSA level, D'Amico risk group, Gleason score, ASA classification, pathological stage, prostate volume, salvage/adjuvant radiotherapy, perioperative complications, and follow-up time. Urinary continence was defined as the use of no pads. For the analysis of long-term urinary continence recovery, we conducted a 1:1 propensity-score matching to control confounders. Results: Among the obese patients, mean BMI was 32.8kg/m2, ranging 30 - 45.7kg/m2. Only 2% was morbidly obese. Obese presented more comorbidities and larger prostates. Median follow-up time was 15 months for the obese. Complications classified as Clavien ≥3 were reported in 5.6% of the obese and in 4.4% of the non-obese men (p=0.423). Median time for continence recovery was 4 months in both groups. In this analysis, HR was 0.989 for urinary continence recovery in obese (95%CI=0.789 - 1.240; p=0.927). Conclusions: Obese can safely undergo RARP with similar continence outcomes comparing to the non-obese men when performed by surgeons with a standardized operative technique. Future studies should perform a subgroup analysis regarding the association of obesity with other comorbidities, intending to optimize patient counseling.

False-Positive Uptake in Splenic Hemangioma on 68Ga-PSMA PET/CT Scan for Late Biochemical Recurrence of Prostate Cancer.

ABSTRACT: A 71-year-old man underwent 68Ga-PSMA PET/CT for evaluation of a late biochemical recurrence after radical prostatectomy. An intense PSMA uptake was identified in spleen. Additional evaluation with a contrast-enhanced MRI showed a splenic lesion consistent with splenic hemangioma.

Simultaneous laparoscopic nephroureterectomy and robot-assisted anterior pelvic exenteration with intracorporeal ileal conduit urinary diversion: step-by-step video-illustrated technique

ABSTRACT Introduction: One of the most remarkable characteristics of urothelial carcinomas is multifocality. However, occurrence of synchronous bladder cancer and upper urinary tract urothelial cancer (UTUC) is exceptional. Minimally invasive approach for these synchronous tumors was just occasionally reported (1-4). The aim of this video article is to describe step-by-step the technique for simultaneous laparoscopic nephroureterectomy and robot-assisted anterior pelvic exenteration with intracorporeal ileal conduit urinary diversion (ICUD). Patients and methods: A 66-year-old female presented with synchronous BCG refractory non-muscle invasive bladder cancer and a right-side UTUC. She was a former smoker and had previously been submitted to multiple transurethral resections of bladder tumor, BCG and right distal ureterectomy with ureteral reimplant. We performed a simultaneous laparoscopic right nephroureterectomy and robot-assisted anterior pelvic exenteration with totally intracorporeal ICUD. Combination of robot-assisted and pure laparoscopic approaches was proposed focusing on optimization of total operative time (TOT). Results: Surgery was uneventful. TOT was of 330 minutes. Operative time for nephroureterectomy, anterior pelvic exenteration and ICUD were 48, 135, 87 minutes, respectively. Estimated blood loss was 150mL. Postoperative course was unremarkable and patient was discharged after 7 days. Histopathological evaluation showed a pT1 high grade urothelial carcinoma plus carcinoma in situ both in proximal right ureter and bladder, with negative margins. Twelve lymph nodes were excised, all of them negative. Conclusion: In our preliminary experience, totally minimally invasive simultaneous nephroureterectomy and cystectomy with intracorporeal ICUD is feasible. Pure laparoscopic approach to upper urinary tract may be a useful tactic to reduce total operative time.

Cost-Effectiveness Analysis of Prostate Cancer Screening in Brazil.

INTRODUCTION: Prostate cancer is one of the most common malignancies among men worldwide. Prostate-specific antigen (PSA) screening shows uncertain benefits and harms from clinical and economic perspectives, resulting in an important impact on healthcare systems. Because of nonstandardized studies and substantial differences among populations, data are still inconclusive. OBJECTIVE: The objective of this study was to carry out long-term cost-effectiveness and cost-utility analysis on the PSA-screened population from the service provider's perspective in the Brazilian population. METHODS: We performed a cost-effectiveness and cost-utility analysis using clinical outcomes obtained from 9692 men enrolled in the PSA screening program. Prostate cancer treatments, 5-year follow-up outcomes, and all related costs were examined. Data were compared with a nonscreened prostate cancer population to calculate incremental cost-effectiveness ratio (ICER) and incremental cost-utility ratio (ICUR). ICER and ICUR were compared with the Brazilian-established willingness-to-pay (WTP) threshold (WTP = R$ 114 026.55). RESULTS: A total of 251 of 9692 men had a diagnosis of prostate cancer (2.6%), of which 90% had localized disease. Two hundred and five patients were treated as follows: surgery (45.37%); radiation therapy (11.22%); radiation plus androgen deprivation therapy (21.95%); active surveillance (13.17%); exclusive androgen deprivation therapy (7.32%); and watchful waiting (0.98%). Two simulated cohorts were compared based on screening and nonscreening groups. Values obtained were-ICER of R$ 44 491.39 per life saved and ICUR of R$ 10 851.56 per quality-adjusted life year (QALY) gained-below the Brazilian WTP threshold and showed cost-effectiveness and cost-utility advantages. CONCLUSION: According to the Brazilian WTP, PSA screening is a cost-effective policy from a hospital and long-term perspective and should have more standardized studies developed in different populations and economies.

Prostate Cancer Screening in Brazil: a single center experience in the public health system

ABSTRACT Purpose: Incidence and mortality of prostate cancer (PCa) are still increasing in developing countries. Limited access to the health system or more aggressive disease are potential reasons for this. Ethnic and social differences in developed countries seem to make inappropriate to extrapolate data from other centers. We aim to report the epidemiological profile of a PSA-screened population from a cancer center in Brazil. Materials and Methods: We retrospectively selected 9.692 men enrolled in a PCa prevention program, comprising total PSA level and digital rectal examination at the first appointment, associated with complementary tests when necessary. Men aged over 40 years-old were included after shared decision-making process. Prostate biopsy (TRUS) was performed when clinically suspected for PCa. After the diagnosis, patients underwent appropriate treatment. Results: TRUS was performed in 5.5% of men and PCa incidence was 2.6%. Overall ratio between number of patients who needed to be screened in order to diagnose one cancer was 38.9 patients, with 2.1 biopsies performed to diagnose a cancer. Positive predictive value (PPV) of TRUS biopsy in this strategy was 47.2%, varying from 38.5% (<50 years-old) to 60% (>80 years-old). We evidenced 70 patients (27.9%) classified as low risk tumors, 74 (29.5%) as intermediate risk, and 107 (42.6%) as high-risk disease. Conclusions: PSA-screening remains controversial in literature. In front of a huge miscegenated people and considering the big proportion of high-risk PCa, even in young men diagnosed with the disease, it is imperative to inform patients and health providers about these data particularities in Brazil.

Prognostic Impact of Loss of SETD2 in Clear Cell Renal Cell Carcinoma.

PURPOSE: To evaluate the prognostic impact of immunohistochemical expression of SETD2 in patients with clear cell renal cell carcinoma (ccRCC). PATIENTS AND METHODS: A total of 662 patients with primary or metastatic ccRCC were evaluated. Two genitourinary pathologist reviewed all of the cases for uniform reclassification and determined the selection of the most representative tumor areas for construction of the tissue microarray (TMA). RESULTS: SETD2 nuclear staining showed that 101 areas (15.3%) had negative expression, and 561 areas (84,7%) had positive expression of SETD2. The protein expression of SETD2 was associated with clinical stage (P < .001), pathological stage (P < .001), tumor size (P < .001), perinephric fat invasion (P < .001), Eastern Cooperative Oncology Group status (P = .004), surgery type (P < .001), International Society of Urologic Pathologists grade (P < .001), and tumor necrosis (P < .001). SETD2 influenced disease-specific survival (DSS) and overall survival (OS). DSS rates in patients with positive and negative expression of SETD2 were 90.2% and 58.4%, respectively (P < .001). OS rates in patients with positive and negative expression of SETD2 were 87% and 55.4%, respectively (P < .001). In a multivariate Cox analysis, low SETD2 expression was an independent predictor of DSS (hazard ratio [HR], 1.690; 95% confidence interval [CI], 1.0582.700; P = .031) and OS (HR, 1.641; 95% CI, 1.039-2.593; P = .037). CONCLUSION: Our study showed that the negative expression of SETD2 was associated with a worse prognosis, and it was an independent predictor of survival in patients with ccRCC. We believe that the protein expression of SETD2 is an important biomarker in the management of patients with ccRCC.

Consensus on Treatment and Follow-Up for Biochemical Recurrence in Castration-Sensitive Prostate Cancer: A Report From the First Global Prostate Cancer Consensus Conference for Developing Countries.

PURPOSE: To present a summary of the treatment and follow-up recommendations for the biochemical recurrence in castration-sensitive prostate cancer (PCa) acquired through a questionnaire administered to 99 PCa experts from developing countries during the Prostate Cancer Consensus Conference for Developing Countries. METHODS: A total of 27 questions were identified as related to this topic from more than 300 questions. The clinician's responses were tallied and presented in a percentage format. Topics included the use of imaging for staging biochemical recurrence, treatment recommendations for three different clinical scenarios, the field of radiation recommended, and follow-up. Each question had 5-7 relevant response options, including "abstain" and/or "unqualified to answer," and investigated not only recommendations but also if a limitation in resources would change the recommendation. RESULTS: For most questions, a clear majority (> 50%) of clinicians agreed on a recommended treatment for imaging, treatment scenarios, and follow-up, although only a few topics reached a consensus > 75%. Limited resources did affect several areas of treatment, although in many cases, they reinforced more stringent criteria for treatment such as prostate-specific antigen values > 0.2 ng/mL and STAMPEDE inclusion criteria as a basis for recommending treatment. CONCLUSION: A majority of clinicians working in developing countries with limited resources use similar cutoff points and selection criteria to manage patients treated for biochemically recurrent castration-sensitive PCa.
