RESUMO

Optimal urine-based diagnostic tests (UBDT) minimize unnecessary follow-up cystoscopies in patients with non-muscle-invasive bladder-cancer (NMIBC), while accurately detecting high-grade bladder-cancer without false-negative results. Such UBDTs have not been comprehensively described upon a broad, validated dataset, resulting in cautious guideline recommendations. Uromonitor®, a urine-based DNA-assay detecting hotspot alterations in TERT, FGFR3, and KRAS, shows promising initial results. However, a systematic review merging all available data is lacking. Studies investigating the diagnostic performance of Uromonitor® in NMIBC until November 2023 were identified in PubMed, Embase, Web-of-Science, Cochrane, Scopus, and medRxiv databases. Within aggregated analyses, test performance and area under the curve/AUC were calculated. This project fully implemented the PRISMA statement. Four qualifying studies comprised a total of 1190 urinary tests (bladder-cancer prevalence: 14.9%). Based on comprehensive analyses, sensitivity, specificity, positive-predictive value/PPV, negative-predictive value/NPV, and test accuracy of Uromonitor® were 80.2%, 96.9%, 82.1%, 96.6%, and 94.5%, respectively, with an AUC of 0.886 (95%-CI: 0.851-0.921). In a meta-analysis of two studies comparing test performance with urinary cytology, Uromonitor® significantly outperformed urinary cytology in sensitivity, PPV, and test accuracy, while no significant differences were observed for specificity and NPV. This systematic review supports the use of Uromonitor® considering its favorable diagnostic performance. In a cohort of 1000 patients with a bladder-cancer prevalence of ~15%, this UBDT would avert 825 unnecessary cystoscopies (true-negatives) while missing 30 bladder-cancer cases (false-negatives). Due to currently limited aggregated data from only four studies with heterogeneous quality, confirmatory studies are needed.

RESUMO

PURPOSE: Renal cysts comprise benign and malignant entities. Risk assessment profits from CT/MRI imaging using the Bosniak classification. While Bosniak-IIF, -III, and -IV cover complex cyst variants, Bosniak-IIF and -III stand out due to notorious overestimation. Contrast-enhanced ultrasound (CEUS) is promising to overcome this deficit but warrants standardization. This study addresses the benefits of a combined CEUS and CT/MRI evaluation of renal cysts. The study provides a realistic account of kidney tumor boards' intricacies in trying to validate renal cysts. METHODS: 247 patients were examined over 8 years. CEUS lesions were graded according to CEUS-Bosniak (IIF, III, IV). 55 lesions were resected, CEUS-Bosniak- and CT/MRI-Bosniak-classification were correlated with histopathological diagnosis. Interobserver agreement between the classifications was evaluated statistically. 105 lesions were followed by ultrasound, and change in CEUS-Bosniak-types and lesion size were documented. RESULTS: 146 patients (156 lesions) were included. CEUS classified 67 lesions as CEUS-Bosniak-IIF, 44 as CEUS-Bosniak-III, and 45 as CEUS-Bosniak-IV. Histopathology of 55 resected lesions revealed benign cysts in all CEUS-Bosniak-IIF lesions (2/2), 40% of CEUS-Bosniak-III and 8% of CEUS-Bosniak-IV, whereas malignancy was uncovered in 60% of CEUS-Bosniak-III and 92% of CEUS-Bosniak-IV. Overall, CEUS-Bosniak-types matched CT/MRI-Bosniak types in 58% (fair agreement, κ = 0.28). CEUS-Bosniak resulted in higher stages than CT/MRI-Bosniak (40%). Ultrasound follow-up of 105 lesions detected no relevant differences between CEUS-Bosniak-types concerning cysts size. 99% of lesions showed the same CEUS-Bosniak-type. CONCLUSION: The CEUS-Bosniak classification is an essential tool in clinical practice to differentiate and monitor renal cystic lesions and empowers diagnostic work-up and patient care.

RESUMO

Prostate cancer represents one of the most common malignant tumors in male patients in Germany. The pathological reporting of radical prostatectomy specimens following a structured process constitutes an excellent prototype for the introduction of software-based standardized structured reporting in pathology. This can lead to reports of higher quality and could create a fundamental improvement for future AI applications. A software-based reporting template was used to generate standardized structured pathological reports of radical prostatectomy specimens of patients treated at the University Hospital Klinikum rechts der Isar of Technische Universität München, Germany. Narrative reports (NR) and standardized structured reports (SSR) were analyzed with regard to completeness, and clinicians' satisfaction with each report type was evaluated. SSR show considerably higher completeness than NR. A total of 10 categories out of 32 were significantly more complete in SSR than in NR (p < 0.05). Clinicians awarded overall high scores in NR and SSR reports. One rater acknowledged a significantly higher level of clarity and time saving when comparing SSR to NR. Our findings highlight that the standardized structured reporting of radical prostatectomy specimens, qualifying as level 5 reports, significantly increases objectively measured content quality and the level of completeness. The implementation of nationwide SSR in Germany, particularly in oncologic pathology, can serve pathologists, clinicians, and patients.

RESUMO

BACKGROUND: Transrectal prostate biopsy (TRPB) is the gold standard for prostate cancer diagnosis and among the most common urological interventions. Short-term antibiotic prophylaxis (PAP) is recommended for TRPB. Fluoroquinolone-PAP as standard of care needs to be revaluated due to the restrictions on the use of fluoroquinolone antibiotics by the German Federal Institute for Drugs and Medical Devices. OBJECTIVES: The aim of the study was to analyze clinical practice of PAP for TRPB with focus on infectious complications and potential differences between fluoroquinolone-PAP and cotrimoxazole-PAP. METHODS: We performed a retrospective monocentric study of clinical and microbiological characteristics of patients with TRPB between 3 January 2019 and 28 January 2021. RESULTS: A total of 508 men were included; median age was 68 years. In all, 55.9% of our cohort received cotrimoxazole-PAP and 40.0% fluoroquinolone-PAP. Postinterventional complications occurred in 5.5%, of those 50.0% were infectious complications. Complication rate did not differ between patients with fluoroquinolone-PAP and cotrimoxazole-PAP. Urinary cultures in case of postinterventional complications yielded pathogens with antimicrobial resistance against the used PAP substance indicating selection of resistant bacteria. CONCLUSION: Cotrimoxazole-PAP for TRPB is not associated with an increase of infectious complications compared to fluoroquinolone-PAP. Cultures obtained prior to TRPB to identify antimicrobial resistance facilitate targeted PAP and therefore can reduce complications.

RESUMO

OBJECTIVES: Acute kidney injury following cardiac surgery depicts a severe clinical problem that is strongly associated with adverse short- and long-term outcome. We analyzed two common genetic polymorphisms that have previously been linked to renal failure and inflammation, and have been supposed to be associated with cardiac surgery associated-acute kidney injury (CSA-AKI). METHODS: A total of 1415 consecutive patients who underwent elective cardiac surgery with CPB at our institution were prospectively enrolled. Patients were genotyped for Apolipoprotein E (ApoE E2,E3,E4) (rs429358 and rs7412) and TNF-α-308 G > A (rs1800629). RESULTS: Demographic characteristics and procedural data revealed no significant differences between genotypes. No association between ApoE (E2,E3,E4) and TNF-α-308 G > A genotypes and the RIFLE criteria could be detected. Several multiple linear regression analyses for postoperative creatinine increase revealed highly significant associations for aortic cross clamp time (p < 0.001), CPB-time (p < 0.001), norepinephrine (p < 0.001), left ventricular function (p = 0.004) and blood transfusion (p < 0.001). No associations were found for ApoE (E2,E3,E4) and TNF-α-308 G > A genotypes or baseline creatinine. When the sample size is 1415, the multiple linear regression test of R(2 )= 0 for seven covariates assuming normal distribution will have at least 99% power with significance level 0.05 to detect an R(2) of 0.108 or 0.107 as observed in the data. CONCLUSIONS: ApoE (E2,E3,E4) polymorphism and the TNF-α-308 G > A polymorphism are not associated with renal injury after CPB.

RESUMO

AIM: The feasibility and safety of a presurgical treatment approach with sunitinib for renal cell carcinoma (RCC) with level III/IV tumour thrombus in the inferior vena cava (IVC) were to be evaluated and its potential ability to reduce the surgical morbidity explored. PATIENTS AND METHODS: In our institution, we treated five consecutive patients with suspected RCC and a level III/IV IVC tumour thrombus with preoperative sunitinib (50 mg, 4 weeks on, 2 weeks off). Side dose effects were assessed and the effect on the tumour size and the dependent surgical approach documented with a computed tomographic scan before and after the treatment. The data were analyzed retrospectively. RESULTS: The overall tolerability to presurgical sunitinib was good. All procedures were carried out without perioperative complications. In four patients, a reduction in tumour size was observed, which resulted in avoidance of a bicavital surgical approach with cardiopulmonary bypass in one patient. This patient was diagnosed with papillary renal cancer; the other four patients had clear cell carcinomas. CONCLUSION: Presurgical treatment with sunitinib is able to ease surgery for RCC tumour thrombi regardless of the histological subtype in selected patients. In our series, surgery was possible without additional morbidity. Two courses of a presurgical therapy with sunitinib seems to be an appropriate duration. In accordance with previously published data, presurgical sunitinib treatment may become more widely used in RCC with level III/IV IVC tumour thrombi but administered with restraint in cases of level I/II thrombi. The effects on the risk of recurrence and survival remain to be evaluated prospectively.

RESUMO

OBJECTIVE: Cardiac surgery using cardiopulmonary bypass (CPB) initiates an inflammatory response that shows a wide inter-individual range and determines postoperative morbidity. Previous research suggests that genetic diversity contributes to individual susceptibility to perioperative trauma and stress. Nevertheless, the genetic triggering of the tumor necrosis factor-alpha (TNF-α) release remains unclear. We tested two genetic single-nucleotide polymorphisms (SNPs) from the promoter region of the TNF-α gene for associations with perioperative TNF-α level after CPB. METHODS: We prospectively included 122 patients, who underwent elective coronary artery bypass grafting (CABG). Patients were genotyped for TNF-α -863 C/A (rs1800630) and TNF-α -308 G/A (rs1800629). Plasma level of TNF-α was obtained preoperatively, at the end of CPB, 6h postoperatively, and on the first postoperative day (POD). RESULTS: Demographic characteristics and operative data revealed no significant differences between the different genotypes. Multiple linear regression analyses revealed significant associations for the TNF-α 863 C/A polymorphism: the major -863 CC variant was associated with higher TNF-α level preoperatively (p = 0.003), after CPB (p = 0.005), and 6h postoperatively (p = 0.010), independently from CPB time, left ventricle (LV) function and age. Contrarily, the AA allele had lower TNF-α level preoperatively (p = 0.008), after surgery (p = 0.024) and 6h postoperatively (p = 0.001). For the TNF-α 308 G/A polymorphism, only few significant associations could be observed: -308 GG carriers were associated with lower TNF-α level immediately after CPB (p = 0.020), whereas 308 AA carriers were significantly associated with elevated TNF-α level preoperatively (p = 0.032) and immediately after CPB (p = 0.05). No heterozygote variant of both SNPs revealed any significant associations with perioperative TNF-α level. CONCLUSIONS: The current study suggests that the major -863 CC variant determines elevated TNF-α level preoperatively and throughout the postoperative course after CPB.

RESUMO

BACKGROUND: Antifibrinolytics are widely used in cardiac surgery to reduce bleeding. Allogeneic blood transfusion, even in primary cardiac operations with low blood loss, is still high. In the present study we evaluated the impact of tranexamic acid compared to aprotinin on the transfusion incidence in cardiac surgical patients with low risk of bleeding. METHODS: This prospective, randomized, double-blind study included 220 patients undergoing primary coronary artery revascularization (coronary artery bypass grafting [CABG]) or aortic valve replacement (AVR). Randomized in blocks of 20, patients received either tranexamic acid (approximately 6 g) or full-dose aprotinin (approximately 5-6 x 10(6) Kallikrein Inhibiting Units). Transfusion was guided by a strict transfusion algorithm. Molecular markers of hemostasis were determined to assess differences in the mode of action of the two drugs. Primary end-points were the incidence of allogeneic red cell transfusion and 24-h postoperative blood loss. Data were analyzed according to the intention-to-treat principle and compared using the chi(2) and Mann-Whitney U-test. RESULTS: Two-hundred-twenty patients were enrolled (CABG: 134, AVR: 86). In the aprotinin Group 47% of patients received allogeneic blood during the hospital stay as compared to 61% in the tranexamic acid group (P = 0.036). Aprotinin conferred a 23% reduction in allogeneic transfusion risk (RR 0.77, 95% CI 0.53-0.88). Overall, no significant difference in postoperative bleeding was observed, although 24-h blood loss was reduced in aprotinin-treated CABG patients (500, 350-750 mL vs 650, 475-875 mL (median, 25th-75th percentile); P = 0.039). Despite the lower transfusion rate, the hemoglobin concentration on the first postoperative day was higher in the aprotinin group (11.3, 9.9-12.1 vs 10.6, 9.9-11.6 mg/dL; P = 0.023). The fibrinolytic activity at the end of operation determined by D-Dimer was comparable in both groups. (0.15, 0.11-0.17 mg/L [aprotinin] versus 0.18, 0.12-0.24 mg/L [tranexamic acid]). The activated partial thromboplastin time was prolonged up to 4 h postoperatively in the aprotinin group, while the heparin requirement was reduced: 19% of the patients in the aprotinin group and 45% in the tranexamic acid group received at least one additional bolus heparin during cardiopulmonary bypass (P < 0.001). Troponin T levels postoperatively and on postoperative day 1 were significantly higher in the tranexamic acid group (P = 0.017). No differences in renal, cardiac, or mortality outcomes were observed. CONCLUSION: Considering the rate of transfusion of red blood cells, tranexamic acid was slightly inferior in patients undergoing CABG, but there was no difference in patients receiving AVR. Tranexamic acid seems to be less effective in operations with increased bleeding such as CABG. Clinical benefit depends on specific patient and institution characteristics (ClinicalTrials.gov NCT00396760).
