RESUMEN

PURPOSE: Smoking is a recognized risk factor for bladder BC and lung cancer LC. We investigated the enduring risk of BC after smoking cessation using U.S. national survey data. Our analysis focused on comparing characteristics of LC and BC patients, emphasizing smoking status and the latency period from smoking cessation to cancer diagnosis in former smokers. MATERIALS AND METHODS: We analyzed data from the National Health and Examination Survey (2003-2016), identifying adults with LC or BC history. Smoking status (never, active, former) and the interval between quitting smoking and cancer diagnosis for former smokers were assessed. We reported descriptive statistics using frequencies and percentages for categorical variables and median with interquartile ranges (IQR) for continuous variables. RESULTS: Among LC patients, 8.9% never smoked, 18.9% active smokers, and 72.2% former smokers. Former smokers had a median interval of 8 years (IQR 2-12) between quitting and LC diagnosis, with 88.3% quitting within 0-19 years before diagnosis. For BC patients, 26.8% never smoked, 22.4% were active smokers, and 50.8% former smokers. Former smokers had a median interval of 21 years (IQR 14-33) between quitting and BC diagnosis, with 49.3% quitting within 0-19 years before diagnosis. CONCLUSIONS: BC patients exhibit a prolonged latency period between smoking cessation and cancer diagnosis compared to LC patients. Despite smoking status evaluation in microhematuria, current risk stratification models for urothelial cancer do not incorporate it. Our findings emphasize the significance of long-term post-smoking cessation surveillance and advocate for integrating smoking history into future risk stratification guidelines.

RESUMEN

OBJECTIVES: To apply a new evidence-gathering methodology, called reverse systematic review (RSR), to analyse the influence of different continence classification criteria on urinary continence rates among open retropubic radical prostatectomy (RRP), laparoscopic RP (LRP) and robot-assisted RP (RARP). MATERIALS AND METHODS: A search was carried out in eight databases between 2000 and 2020 through systematic reviews (SRs) studies referring to RRP, LRP or RARP (80 SRs). All references used in these SRs were captured referring to 910 papers in an overall database called the 'EVIDENCE Database'. A total of 422 studies related to post-RP urinary continence were selected for the final analysis, totalling 782 reports referring to 193 618 patients. RESULTS: Overall, 206 (26.4%) reports for RRP, 243 (31.0%) reports for LRP, and 333 (42.6%) reports for RARP were found. Mean overall continence rates, respectively for RRP, LRP and RARP, were: 42%, 34% and 42% at 1 month; 62%, 64% and 65% at 3 months; 73, 77 and 79% at 6 months; and 81%, 85% and 86% at 12 months. The most used criterion was 'No pad' (53.3%), followed by 'Safety pad' (19.3%), 'Not described' (10.6%), and 'No leak' (9.9%). 'No pad' showed the lowest discrepancy in continence rates in each period compared to the overall average for each technique, demonstrating less ability to influence the final results favouring any of the techniques. CONCLUSION: The RSR demonstrated that the 'No pad' criterion was the most used in the literature and showed the lowest bias capable of influencing the results and favouring any of the techniques and is the fairest option for future comparisons.

RESUMEN

PURPOSE: To understand the effect of Nitazoxanide (NTZ), Rapamycin, Thalidomide, alone and in combination with BCG on bladder cancer (BC) histopathology and programmed death-ligand 1 (PD-L1) and anti-cytotoxic T lymphocyte antigen 4 (CTLA4) expression. METHODS: Female Fisher-344 rats underwent intravesical N-methyl-N-nitrosourea (MNU) followed by weekly intravesical treatment with saline (controls, n = 10), BCG (n = 10), NTZ (n = 8), BCG plus NTZ (n = 8), Rapamycin (n = 10) BCG plus Rapamycin (n = 10), Thalidomide (n = 10), and BCG plus Thalidomide (n = 10), and euthanized after 8 weeks and their bladders were investigated for BC and PD-L1 and CTLA4 expression. RESULTS: Rapamicyn alone and in combination with BCG had the lowest number of bladder neoplasias in the histopathology exam (1/10). Neoplastic lesions were found in 4/10 BCG recipients, 5/10 Thalidomide recipients, 4/10 Thalidomide plus BCG recipients, 5/8 NTZ and 3/8 NTZ plus BCG recipients. Adding NTZ to BCG increased the expression of PD-L1 and adding Rapamycin or Thalidomide decreased PD-L1 and CTLA4 expression compared to BCG alone. Rapamycin alone significantly increased CTLA4 and slightly increased PD-L1 expression but its combination with BCG significantly decreased both markers. Thalidomide had a similar effect; however, it was only slightly different from the control and BCG alone groups. CONCLUSION: Intravesical BCG combination treatment seems to effectively prevent BC development in an immunecompetent clinically relevant animal model, introducing Thalidomide, Nitazoxanide, and specially Rapamycin as candidates in the intravesical immunotherapy advancement. Our study contributes in understanding the mechanism of cancer immunotherapy.

RESUMEN

OBJECTIVE: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). MATERIALS AND METHODS: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. RESULTS: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. CONCLUSION: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.

RESUMEN

BACKGROUND: The Bacillus Calmette-Guérin (BCG) vaccine may confer cross-protection against viral diseases in adults. This study evaluated BCG vaccine cross-protection in adults with convalescent coronavirus disease 2019 (COVID-19). METHOD: This was a multicenter, prospective, randomized, placebo-controlled, double-blind phase III study (ClinicalTrials.gov: NCT04369794). SETTING: University Community Health Center and Municipal Outpatient Center in South America. PATIENTS: a total of 378 adult patients with convalescent COVID-19 were included. INTERVENTION: single intradermal BCG vaccine (n = 183) and placebo (n = 195). MEASUREMENTS: the primary outcome was clinical evolution. Other outcomes included adverse events and humoral immune responses for up to 6 months. RESULTS: A significantly higher proportion of BCG patients with anosmia and ageusia recovered at the 6-week follow-up visit than placebo (anosmia: 83.1% vs. 68.7% healed, p = 0.043, number needed to treat [NNT] = 6.9; ageusia: 81.2% vs. 63.4% healed, p = 0.032, NNT = 5.6). BCG also prevented the appearance of ageusia in the following weeks: seven in 113 (6.2%) BCG recipients versus 19 in 126 (15.1%) placebos, p = 0.036, NNT = 11.2. BCG did not induce any severe or systemic adverse effects. The most common and expected adverse effects were local vaccine lesions, erythema (n = 152; 86.4%), and papules (n = 111; 63.1%). Anti-severe acute respiratory syndrome coronavirus 2 humoral response measured by N protein immunoglobulin G titer and seroneutralization by interacting with the angiotensin-converting enzyme 2 receptor suggest that the serum of BCG-injected patients may neutralize the virus at lower specificity; however, the results were not statistically significant. CONCLUSION: BCG vaccine is safe and offers cross-protection against COVID-19 with potential humoral response modulation. LIMITATIONS: No severely ill patients were included.

RESUMEN

PURPOSE: To report the prevalence of the definitions used to identify post-prostatectomy incontinence (PPI) after laparoscopic radical prostatectomy (LRP), and to compare the rates of PPI over time under different criteria. MATERIALS AND METHODS: In the period from January 1, 2000, until December 31, 2017, we used a recently described methodology to perform evidence acquisition called reverse systematic review (RSR). The continence definition and rates were evaluated and compared at 1, 3, 6, 12, and >18 months post-operative. Moreover, the RSR showed the "natural history" of PPI after LRP. RESULTS: We identified 353 review articles in the systematized search, 137 studies about PPI were selected for data collection, and finally were included 203 reports (nr) with 51.436 patients. The most used criterion of continence was No pad (nr=121; 59.6%), the second one was Safety pad (nr=57; 28.1%). A statistically significant difference between continence criteria was identified only at >18 months (p=0.044). From 2013 until the end of our analysis, the Safety pad and Others became the most reported. CONCLUSION: RSR revealed the "natural history" of PPI after the LRP technique, and showed that through time the Safety pad concept was mainly used. However, paradoxically, we demonstrated that the two most utilized criteria, Safety pad and No pad, had similar PPI outcomes. Further effort should be made to standardize the PPI denomination to evaluate, compare and discuss the urinary post-operatory function.

RESUMEN

PURPOSE: Evaluate tryptophan and thymine (TT) impact on carcinogenesis and intravesical BCG bladder cancer treatment. METHODS: After identification of TT in vitro inhibitory effect in multiple cancer cell cultures, bladder cancer animal model was induced by MNU intravesical instillations and randomized into four groups: Control (n = 9), BCG (n = 9), TT (n = 7), and BCG + TT (n = 8). BCG groups received intravesical 106 CFU BCG in 0.2 ml saline for 6 consecutive weeks and TT groups received 1 g/kg (1:1) of TT via daily gavage. After 15 wk of protocol, animals were euthanized and the urinary bladders submitted to histopathology, immunohistochemistry, and Western blotting. RESULTS: Urothelial cancer was identified in 100%, 85.7%, 44.5%, and 37.5% of Control, TT, BCG, and BCG + TT groups, respectively. Cell proliferation marked by nuclear Ki-67 was higher in the Control compared to animals in the other groups (P = 0.03). BCG, TT, and BCG + TT groups showed proliferative cell decline and TLR4/5 labeling increase in the urothelium. BCG decreased the urothelial VEGF labeling, even in TT association. CONCLUSION: TT inhibit urothelial carcinogenesis and potentiate the intravesical BCG in the treatment of bladder cancer by reducing cell proliferation and activating TLRs.

RESUMEN

PURPOSE: Nitazoxanide (NTZ) has shown a promising antitumoral effect, the current study compared the anti-neoplastic effects of intravesical NTZ and BCG plus NTZ in NMIBC animal model. METHODS: 30 rats, Fisher 344 were instilled with 4 intravesical doses of 1.5 mg/kg of N-methyl-N-nitrosourea (MNU) every 15 days for BC induction. The animals were divided into 3 groups (Group BCG 106 UFC - 1 mg of BCG; Group NTZ - 300 mg/kg of NTZ; Group NTZ + BCG - simultaneous treatment of BCG and NTZ) and received weekly intravesical treatment for 6 consecutive weeks. Animals were submitted to ultrasound imaging and euthanasia, their bladders were collected and histopathological, immunohistochemical tests (ki67 e c-Myc) and Western Blotting (PI3K, mTOR, and p-4E-BP) were performed. RESULTS: Histopathological tests showed 66.67%, 62.5% and 37.5% incidence of BC in animals treated with BCG, NTZ, and NTZ + BCG, respectively. Nuclear positivity for ki-67 in BC animals were 12.4% (IC 10.1-14.6%), 13.2% (IC 10.5-15.9%) and 8.8% (IC 6.0-11.6%) in BCG, NTZ and NTZ + BCG group, respectively (p = 0.063). Between animals with carcinoma, c-Myc strong positive was 40.10% in NTZ, 32.2% in BCG and 19.90% in the NTZ + BCG group (p < 0.001). Blotting has shown mTOR (p = 0.0473) and PI3K inhibition (p = 0.0349) in the presence of BCG, added to 4-EBP inhibition in the presence of NTZ (p = 0.0004). CONCLUSIONS: Results show the possible synergy between the gold standard BC treatment BCG and NTZ, in which multiple targets inhibition such as c-Myc and downstream mTOR, p-4E-BP and PI3K might play a role.

RESUMEN

PURPOSE: To evaluate the underexplored context of cystoscopy adherent versus non-adherent patients in the follow-up of urothelial high-risk non-muscle-invasive bladder cancer (NMIBC). METHODS: We performed a retrospective study (2005-2016) that evaluated patients´ demographical characteristics, histopathological data, recurrence, progression and cancer-specific mortality between adherent and non-adherents patients in the first 3 years of a proposed cystoscopy protocol. RESULTS: Among the 198 included patients, comparing cystoscopy non-adherent (n = 36, 18%) and adherent patients (n = 162, 82%), there was no demographic or histopathological differences; the rates of disease recurrence, progression and cancer-specific mortality were 15 (41.7%) versus 68 (42.2%), p = 0.58; 12 (33.3%) versus 28 (17.9%), p = 0.014 and 4 (11.1%) versus 19 (11.7%), p = 0.98, respectively. Cystoscopy non-adherence was associated with an inferior number of urinary cytology (p < 0.001) and 2.33 HR for cancer progression, p = 0.014, (95% CI 1.18-4.59). CONCLUSIONS: Non-adherence to follow-up cystoscopy in NMIBC is associated with more than twice progression risk. Future studies are needed to confirm our results and correlate cystoscopy non-adherence to other covariates.

RESUMEN

PURPOSE: To evaluate mini-sling long-term results and correlate them to failure predictors. Many studies show comparable results among different single-incision slings developed as an attempt to reduce complications while keeping good results, but there is a lack of evidence about mini-slings outcomes in the long term. METHODS: This prospective, single-center study evaluated 40 patients for long-term outcomes after mini-sling placement. Objective cure was defined as leakage of less than 1 g in 1-hour pad-test and no leakage at Valsalva maneuver. An objective improvement was defined as leakage of a maximum 50% of the preoperative test. Subjective continence was considered as a zero score at International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). Patients were also evaluated for comorbidities and previous surgeries. RESULTS: The mean age was 56 (±9.3) years, the mean ICIQ-SF score was 16 (±2.98) before surgery and 3.5 (± 5) at last follow-up, showing sustained improvement in the long term, mean 100 (84-109) months follow-up. The objective results show 67.5% of success, 17.5% of improvement, and 15% of failure. Age and parity were not related to outcomes (p = 0.33), but previous surgeries increase failure rate with 5.66 OR (p = 0.04). Success, improvement, and failure rates were 85, 10, and 5% for treatment-naive patients versus 50, 25, and 25% for patients with previous surgeries, respectively. CONCLUSION: Mini-sling Ophira shows good long-term results with low complications rates in patients without previous anti-incontinence surgery. Randomized trials are necessary to compare mini-slings results to other mid-urethral slings in recurred stress urinary incontinence.

RESUMEN

PURPOSE: To identify how the most frequently used parameters in daily clinical practice diagnosing bladder outlet obstruction (BOO) due to benign prostate hyperplasia (BPH) correlate to each other. MATERIALS AND METHODS: The study included 452 patients with lower urinary tract symptoms (LUTS) of the UNICAMP urology outpatient clinic of LUTS. INCLUSION CRITERIA: patients with BOO due to BPH who agreed to participate in the study. EXCLUSION CRITERIA: patients with urinary tract infection, neurological diseases that compromised the lower urinary tract, prior prostatic surgery, radiotherapy or urethral stenosis. Patient assessment: history, international prostate symptoms score (IPSS), nocturnal quality of life score (NQoL) questionnaires, physical and digital rectal examination (DRE), PSA, transabdominal ultrasound with intravesical prostate protrusion (IPP), post-mictional residue and free urofl owmetry. RESULTS: There was no strong Spearman correlation among the studied variables. The only moderate correlations occurred between IPSS and NQoL (p<0001; c=0.56) and between IPP and prostate volume (p<0001; c=0.57). Weak correlations between IPP and post-mictional residue (p<0001; c=0.31) and free urofl owmetry (p<0001; c=-0.26); and between IPSS and free urofl owmetry (p<0001, c=-0.21) were observed. CONCLUSION: In this study, we found moderate, weak, very weak and absent correlation among the various parameters used in the diagnosis and management of BOO due to BPH. As the value of these tools is variable, the creation of a logical and objective algorithm was not possible and the treatment is based on the interpretation of clinical symptoms.

RESUMEN

BACKGROUND: We investigated the role of prostaglandin receptors (e.g. prostaglandin E2 receptor 2 (EP2), EP4) and the efficacy of celecoxib in urothelial tumourigenesis and cancer progression. METHODS: We performed immunohistochemistry in bladder cancer (BC) tissue microarrays, in vitro transformation assay in a normal urothelial SVHUC line, and western blot/reverse transcription-polymerase chain reaction/cell growth assays in BC lines. RESULTS: EP2/EP4 expression was elevated in BCs compared with non-neoplastic urothelial tissues and in BCs from those who were resistant to cisplatin-based neoadjuvant chemotherapy. Strong positivity of EP2/EP4 in non-muscle-invasive tumours or positivity of EP2/EP4 in muscle-invasive tumours strongly correlated with disease progression or disease-specific mortality, respectively. In SVHUC cells, exposure to a chemical carcinogen 3-methylcholanthrene considerably increased and decreased the expression of EP2/EP4 and phosphatase and tensin homologue (PTEN), respectively. Treatment with selective EP2/EP4 antagonist or celecoxib also resulted in prevention in 3-methylcholanthrene-induced neoplastic transformation of SVHUC cells. In BC lines, EP2/EP4 antagonists and celecoxib effectively inhibited cell viability and migration, as well as augmented PTEN expression. Furthermore, these drugs enhanced the cytotoxic activity of cisplatin in BC cells. EP2/EP4 and PTEN were also elevated and reduced, respectively, in cisplatin-resistant BC sublines. CONCLUSIONS: EP2/EP4 activation correlates with induction of urothelial cancer initiation and outgrowth, as well as chemoresistance, presumably via downregulating PTEN expression.

RESUMEN

PURPOSE: To determine the effectiveness and harms of bladder-preserving trimodal therapy (TMT) as a first-line treatment versus radical cystectomy (RC) plus radical pelvic lymphadenectomy in the treatment of muscle-invasive bladder cancer in terms of overall survival. METHODS: We included parallel clinical trials and prospective and retrospective cohort studies that included patients older than 18 years old, diagnosed with muscle-invasive bladder cancer, who underwent TMT compared with RC. The planned comparison was TMT versus RC plus pelvic lymphadenectomy as first-line treatment. The primary outcome was overall survival (OS) and secondary outcomes were salvage cystectomy and cancer-specific survival and progression-free survival. A search strategy was designed for MEDLINE, CENTRAL, Embase, and LILACS. We saturated information with conference abstracts, in progress clinical trials, literature published in non-indexed journals, and other sources of gray literature. Standardized tools assessed the risk of bias independently. We performed the statistical analysis in R v3.4.1 and effect sizes were reported in terms of hazard ratios (HR) and the corresponding 95% confidence intervals (95%CI). Accordingly, we used a random effect model due to the statistical heterogeneity found in included studies. RESULTS: We found 2682 records with the search strategies and, finally, 11 studies were included in the quantitative analysis. The summary HR for OS was 1.06 95%CI (0.85-1.31) I2 = 77%, showing no statistical difference. Regarding cancer-specific survival, the summary HR was 1.23 95%CI (1.04-1.46) I2 = 14%. On the other side, for the progression-free survival, the summary HR was 1.11 95%CI (0.63-1.95) I2 = 78%. Only one study described HR for adverse events (1.37 95%CI 1.16-1.59). CONCLUSION: We found no differences in overall survival and progression-free survival between these two interventions. Nonetheless, we found that cancer-specific survival favored patients who received radical cystectomy.

RESUMEN

PURPOSE: To better understand potential modifiable risk factors guiding preventive interventions against lower urinary tract symptoms (LUTS). METHODS: A prospective cross-sectional study, including healthy men aged 40-70 years under routine urological evaluation, measured the strength of association between the International Prostate Symptom Score (IPSS) and socio-demographic, lifestyle, and health-related factors using logistic and linear regression adjusted for confounding factors. Men with urethral or prostate surgery were excluded. RESULTS: Among 743 men, mean age 59.64 ± 9.66, 22.6% reported moderate, and 5.0% severe LUTS. The adjusted odds of severe LUTS increased with: increasing age (OR = 1.07, 95% CI = 1.05-1.09, p < .0001), increasing prostate volume (OR = 1.02, 95% CI = 1.01-1.04, p = .004), decreasing education (tertiary qualification, no versus yes, OR = 2.34; 95% CI = 1.16-4.70; p = .0133), delayed ejaculation (yes versus no, OR = 2.63, 95% CI = 1.43-4.83, p < .0001), and increasing blood pressure (systolic ≥130 mmHg, OR = 2.03, 95% CI = 1.44-2.86, p < .0001 or diastolic ≥85 mmHg, OR = 1.47, 95% CI = 1.03-2.10, p = .0345); severe LUTS decreased with: increasing the weekly sexual frequency (OR = 0.80, 95% CI = 0.69-0.91, p = .0012) and increasing HDL cholesterol (OR = 0.98, 95% CI = 0.97-0.99, p = .037). Odds were not significant for age of sexual initiation, precocious ejaculation, masturbatory pattern, physical activity, smoking, alcohol consumption, penile length (objective and subjective), abdominal circumference, obesity, comorbid conditions, metabolic syndrome, serum glycaemia, testosterone, SHBG, PSA, and estradiol. CONCLUSIONS: One in every four men under routine urological evaluation who considered themselves healthy present moderate and severe LUTS. Modifiable behavioral (education, sexual frequency, and ejaculation) and health-related (blood pressure and HDL cholesterol) targets were identified for future interventional studies and potential preventive actions and patient counseling.

RESUMEN

OBJECTIVE: To evaluate the overactive bladder (OAB) diagnosis using OAB-V8 and ICIQ-OAB questionnaires in women with different schooling and cultural levels. MATERIALS AND METHODS: Three hundred and eighty six healthy women answered a clinical questionnaire filling out information about schooling, demographic and gynecological data. The OAB-V8 and ICIQ-OAB questionnaires were used to evaluate OAB diagnosis and symptoms; and the QS-F questionnaire, to determine the sexual function. All questionnaires were validated in Portuguese. RESULTS: The mean age was 37.3 years-old. Regarding to schooling level, 23.1% had concluded primary education; 65.8%, secondary school; and 11.1% had higher education. Considering the OAB-V8 (score ≥8), 51.8% of evaluated women had OAB diagnosis. There was a positive linear correlation between the OAB-V8 and ICIQ-OAB questionnaires in its sections "a" (r=0.812, p<0.001) and "b" (r=759, p<0.001). There was a positive linear correlation between age and the amount of time used to answer the OAB-V8, ICIQ-OAB and QS-F questionnaires (p<0.001). The ICIQ-OAB was the hardest to answer for all schooling levels when compared to the other questionnaires. Women who had concluded primary and secondary education significantly demanded more help to answer all questionnaires than those with higher education (p<0.05). Furthermore, women with higher education took significantly less time answering all questionnaires when compared to their less educated counterparts (primary and secondary schooling), since they were quicker to answer each individual question. CONCLUSION: Educational level and ageing had an impact on women response using different questionnaires for OAB and sexual function evaluations.
