PurposeTo develop a novel risk tool that allows the prediction of lymph node invasion (LNI) among patients with prostate cancer (PCa) treated with robot-assisted radical prostatectomy (RARP) and extended pelvic lymph node dissection (ePLND).MethodsWe retrospectively identified 742 patients treated with RARP + ePLND at a single center between 2012 and 2018. All patients underwent multiparametric magnetic resonance imaging (mpMRI) and were diagnosed with targeted biopsies. First, the nomogram published by Briganti et al. was validated in our cohort. Second, three novel multivariable logistic regression models predicting LNI were developed: (1) a complete model fitted with PSA, ISUP grade groups, percentage of positive cores (PCP), extracapsular extension (ECE), and Prostate Imaging Reporting and Data System (PI-RADS) score; (2) a simplified model where ECE score was not included (model 1); and (3) a simplified model where PI-RADS score was not included (model 2). The predictive accuracy of the models was assessed with the receiver operating characteristic-derived area under the curve (AUC). Calibration plots and decision curve analyses were used.ResultsOverall, 149 patients (20%) had LNI. In multivariable logistic regression models, PSA (OR: 1.03; P= 0.001), ISUP grade groups (OR: 1.33; P= 0.001), PCP (OR: 1.01; P= 0.01), and ECE score (ECE 4 vs. 3 OR: 2.99; ECE 5 vs. 3 OR: 6.97; P< 0.001) were associated with higher rates of LNI. The AUC of the Briganti et al. model was 74%. Conversely, the AUC of model 1 vs. model 2 vs. complete model was, respectively, 78% vs. 81% vs. 81%. Simplified model 1 (ECE score only) was then chosen as the best performing model. A nomogram to calculate the individual probability of LNI, based on model 1 was created. Setting our cut-off at 5% we missed only 2.6% of LNI patients.ConclusionsWe developed a novel nomogram that combines PSA, ISUP grade groups, PCP, and mpMRI-derived ECE score to predict the probability of LNI at final pathology in RARP candidates. The application of a nomogram derived cut-off of 5% allows to avoid a consistent number of ePLND procedures, missing only 2.6% of LNI patients. External validation of our model is needed. 相似文献

Background
Few predictive models aimed at predicting the presence of lymph node invasion (LNI) in patients with prostate cancer (PCa) treated with extended pelvic lymph node dissection (ePLND) are available to date.Objective
Update a nomogram predicting the presence of LNI in patients treated with ePLND at the time of radical prostatectomy (RP).Design, setting, and participants
The study included 588 patients with clinically localised PCa treated between September 2006 and October 2010 at a single tertiary referral centre.Intervention
All patients underwent RP and ePLND invariably including removal of obturator, external iliac, and hypogastric nodes.Measurements
Prostate-specific antigen, clinical stage, and primary and secondary biopsy Gleason grade as well as percentage of positive cores were included in univariable (UVA) and multivariable (MVA) logistic regression models predicting LNI and formed the basis for the regression coefficient-based nomogram. The area under the curve (AUC) method was used to quantify the predictive accuracy (PA) of the model.Results and limitations
The mean number of lymph nodes removed and examined was 20.8 (median: 19; range: 10-52). LNI was found in 49 of 588 patients (8.3%). All preoperative PCa characteristics differed significantly between LNI-positive and LNI-negative patients (all p < 0.001). In UVA predictive accuracy analyses, percentage of positive cores was the most accurate predictor of LNI (AUC: 79.5%). At MVA, clinical stage, primary biopsy Gleason grade, and percentage of positive cores were independent predictors of LNI (all p ≤ 0.006). The updated nomogram demonstrated a bootstrap-corrected PA of 87.6%. Using a 5% nomogram cut-off, 385 of 588 patients (65.5%) would be spared ePLND. and LNI would be missed in only 6 patients (1.5%). The sensitivity, specificity, and negative predictive value associated with the 5% cut-off were 87.8%, 70.3%, and 98.4%, respectively. The relatively low number of patients included as well as the lack of an external validation represent the main limitations of our study.Conclusions
We report the first update of a nomogram predicting the presence of LNI in patients treated with ePLND. The nomogram maintained high accuracy, even in more contemporary patients (87.6%). Because percentage of positive cores represents the foremost predictor of LNI, its inclusion should be mandatory in any LNI prediction model. Based on our model, those patients with a LNI risk < 5% might be safely spared ePLND. 相似文献3.

Background
The Rotterdam European Randomized Study of Screening for Prostate Cancer risk calculators (ERSPC-RCs) help to avoid unnecessary transrectal ultrasound-guided systematic biopsies (TRUS-Bx). Multivariable risk stratification could also avoid unnecessary biopsies following multiparametric magnetic resonance imaging (mpMRI).Objective
To construct MRI-ERSPC-RCs for the prediction of any- and high-grade (Gleason score ≥3 + 4) prostate cancer (PCa) in 12-core TRUS-Bx ± MRI-targeted biopsy (MRI-TBx) by adding Prostate Imaging Reporting and Data System (PI-RADS) and age as parameters to the ERSPC-RC3 (biopsy-naïve men) and ERSPC-RC4 (previously biopsied men).Design, setting, and participants
A total of 961 men received mpMRI and 12-core TRUS-Bx ± MRI-TBx (in case of PI-RADS ≥3) in five institutions. Data of 504 biopsy-naïve and 457 previously biopsied men were used to adjust the ERSPC-RC3 and ERSPC-RC4.Outcome measurements and statistical analysis
Logistic regression models were constructed. The areas under the curve (AUCs) of the original ERSPC-RCs and MRI-ERSPC-RCs (including PI-RADS and age) for any- and high-grade PCa were compared. Decision curve analysis was performed to assess the clinical utility of the MRI-ERSPC-RCs.Results and limitations
MRI-ERSPC-RC3 had a significantly higher AUC for high-grade PCa compared with the ERSPC-RC3: 0.84 (95% confidence interval [CI] 0.81–0.88) versus 0.76 (95% CI 0.71–0.80, p < 0.01). Similarly, MRI-ERSPC-RC4 had a higher AUC for high-grade PCa compared with the ERSPC-RC4: 0.85 (95% CI 0.81–0.89) versus 0.74 (95% CI 0.69–0.79, p < 0.01). Unlike for the MRI-ERSPC-RC3, decision curve analysis showed clear net benefit of the MRI-ERSPC-RC4 at a high-grade PCa risk threshold of ≥5%. Using a ≥10% high-grade PCa risk threshold to biopsy for the MRI-ERSPC-RC4, 36% biopsies are saved, missing low- and high-grade PCa, respectively, in 15% and 4% of men who are not biopsied.Conclusions
We adjusted the ERSPC-RCs for the prediction of any- and high-grade PCa in 12-core TRUS-Bx ± MRI-TBx. Although the ability of the MRI-ERSPC-RC3 for biopsy-naïve men to avoid biopsies remains questionable, application of the MRI-ERSPC-RC4 in previously biopsied men in our cohort would have avoided 36% of biopsies, missing high-grade PCa in 4% of men who would not have received a biopsy.Patient summary
We have constructed magnetic resonance imaging-based Rotterdam European Randomized study of Screening for Prostate Cancer (MRI-ERSPC) risk calculators for prostate cancer prediction in transrectal ultrasound-guided biopsy and MRI-targeted biopsy by incorporating age and Prostate Imaging Reporting and Data System score into the original ERSPC risk calculators. The MRI-ERSPC risk calculator for previously biopsied men could be used to avoid one-third of biopsies following MRI. 相似文献4.

Background
The current recommendation of using transrectal ultrasound-guided biopsy (TRUSB) to diagnose prostate cancer misses clinically significant (CS) cancers. More sensitive biopsies (eg, template prostate mapping biopsy [TPMB]) are too resource intensive for routine use, and there is little evidence on multiparametric magnetic resonance imaging (MPMRI).Objective
To identify the most effective and cost-effective way of using these tests to detect CS prostate cancer.Design, setting, and participants
Cost-effectiveness modelling of health outcomes and costs of men referred to secondary care with a suspicion of prostate cancer prior to any biopsy in the UK National Health Service using information from the diagnostic Prostate MR Imaging Study (PROMIS).Intervention
Combinations of MPMRI, TRUSB, and TPMB, using different definitions and diagnostic cut-offs for CS cancer.Outcome measurements and statistical analysis
Strategies that detect the most CS cancers given testing costs, and incremental cost-effectiveness ratios (ICERs) in quality-adjusted life years (QALYs) given long-term costs.Results and limitations
The use of MPMRI first and then up to two MRI-targeted TRUSBs detects more CS cancers per pound spent than a strategy using TRUSB first (sensitivity = 0.95 [95% confidence interval {CI} 0.92–0.98] vs 0.91 [95% CI 0.86–0.94]) and is cost effective (ICER = £7,076 [€8350/QALY gained]). The limitations stem from the evidence base in the accuracy of MRI-targeted biopsy and the long-term outcomes of men with CS prostate cancer.Conclusions
An MPMRI-first strategy is effective and cost effective for the diagnosis of CS prostate cancer. These findings are sensitive to the test costs, sensitivity of MRI-targeted TRUSB, and long-term outcomes of men with cancer, which warrant more empirical research. This analysis can inform the development of clinical guidelines.Patient summary
We found that, under certain assumptions, the use of multiparametric magnetic resonance imaging first and then up to two transrectal ultrasound-guided biopsy is better than the current clinical standard and is good value for money. 相似文献5.

Purpose
To assess adherence rates to pelvic lymph node dissection (PLND) according to National Comprehensive Cancer Network (NCCN) PLND guideline (2% or higher risk) and D’Amico lymph node invasion (LNI) risk stratification (intermediate/high risk) in contemporary North American patients with prostate cancer treated with radical prostatectomy (RP).Material and methods
We relied on 49,358 patients treated with RP and PLND (2010–2013) in SEER database. Adherence rates were quantified and multivariable (MVA) logistic regression analyses tested for independent predictors.Results
According to NCCN PLND guideline and D’Amico LNI classification, PLND was recommended in 63.3% and 64.9% of patients, respectively. Corresponding adherence rates were 68.8% and 69.1%. Adherence rates improved from 67.3% to 71.6% and from 67.6% to 72.0%, respectively, over time. In MVA, more advanced clinical stage, higher biopsy Gleason score and higher number of positive biopsy cores predicted PLNDs that were performed below NCCN LNI nomogram risk threshold. Conversely, lower clinical stage, lower PSA and lower biopsy Gleason score predicted PLND omission in individuals with risk level above NCCN LNI nomogram risk threshold. MVA results for D’Amico classification were virtually identical.Conclusions
Adherence to NCCN PLND guideline and D’Amico LNI classification for purpose of PLND is suboptimal in SEER population-based patients treated with RP. However, adherence rates have improved over time. Patients, who did not undergo PLND despite elevated LNI risk, had more favorable PCa characteristics than the average. Conversely, patients, who underwent PLND despite low-risk, had worse PCa characteristics than the average. 相似文献6.

Objectives
To investigate lymph node invasion (LNI) rates in prostate cancer (PCa) patients. Recent studies demonstrated an inverse stage migration in PCa patients toward more advanced and unfavorable diseases. We hypothesized that this trend is also evident in LNI rates, in PCa patients treated with radical prostatectomy (RP) and pelvic lymph node dissection (PLND).Patients and methods
Within the Surveillance, Epidemiology, and End Results database (2004–2014), we identified patients who underwent RP and PLND. Annual trends of LNI rates and PLND extent were plotted. Univariable and multivariable logistic regression models tested the hypothesis that LNI rates are increasing annually, even after adjustment for clinical or pathological characteristics.Results
Of 96,874 patients treated with RP and PLND, 4.1% (n = 4,002) exhibited LNI. The rate of LNI (2.5%–6.6%.), the mean (6.5–8.4) and median (5–6) number of removed lymph nodes increased during the study period. In multivariable logistic regression models, more contemporary year of diagnosis was associated with higher LNI rate, when year of diagnosis was modeled as a continuous, categorized or cubic spline variable, with adjustment for either clinical (prostate specific antigen, clinical tumor stage, and biopsy Gleason group) or pathological characteristics (pathologic tumor stage and Gleason group), as well as PLND extent (number of removed lymph nodes).Conclusion
We confirmed the hypothesis about increasing LNI rate over time in RP patients. This observation implies an increasing rate of unfavorable PCa defined as LNI. This finding is novel for contemporary epidemiological North American or European databases. 相似文献7.

Introduction
In last 20 years, lymph node staging procedures in breast cancer have been modified. The objective of this study is to describe the evolution of these procedures at our hospital.Methods
A prospective observational study that included women with breast cancer who were treated surgically between 2001 and 2017. Four groups were identified according to the therapeutic regimen and 3 study periods defined by the lymph node dissection.Results
1319 patients met the inclusion criteria. Primary conservative surgery was the most frequent therapy (54.13%), and 615 (46.62%) axillary lymph node dissections (ALND) were performed in the 20-year study period. The percentage of ALND decreased progressively over time, going from 91% in the first period to 34% in the last period. The futile ALND fell to 6.6% in the last year. In the primary conservative surgery, no futile ALND was performed in the last two years.Conclusion
The introduction of sentinel lymph node biopsy and the ACOSOG Z0011 criteria have modified the indication for ALND. Thus, ALND without involvement have been reduced, thereby avoiding the associated morbidity. The study demonstrates the progressive decrease in the indication of lymphadenectomy in the different study groups, similar to reports by other authors. Several clinical trials have described that these changes have not negatively impacted survival. 相似文献8.

Background
The extent of lymph node dissection (LND) in bladder cancer (BCa) patients at the time of radical cystectomy may affect oncologic outcome.Objective
To evaluate whether extended versus limited LND prolongs recurrence-free survival (RFS).Design, setting, and participants
Prospective, multicenter, phase-III trial patients with locally resectable T1G3 or muscle-invasive urothelial BCa (T2-T4aM0).Intervention
Randomization to limited (obturator, and internal and external iliac nodes) versus extended LND (in addition, deep obturator, common iliac, presacral, paracaval, interaortocaval, and para-aortal nodes up to the inferior mesenteric artery).Outcome measurements and statistical analysis
The primary endpoint was RFS. Secondary endpoints included cancer-specific survival (CSS), overall survival (OS), and complications. The trial was designed to show 15% advantage of 5-yr RFS by extended LND.Results and limitations
In total, 401 patients were randomized from February 2006 to August 2010 (203 limited, 198 extended). The median number of dissected nodes was 19 in the limited and 31 in the extended arm. Extended LND failed to show superiority over limited LND with regard to RFS (5-yr RFS 65% vs 59%; hazard ratio [HR] = 0.84 [95% confidence interval 0.58–1.22]; p = 0.36), CSS (5-yr CSS 76% vs 65%; HR = 0.70; p = 0.10), and OS (5-yr OS 59% vs 50%; HR = 0.78; p = 0.12). Clavien grade ≥3 lymphoceles were more frequently reported in the extended LND group within 90 d after surgery. Inclusion of T1G3 tumors may have contributed to the negative study result.Conclusions
Extended LND failed to show a significant advantage over limited LND in RFS, CSS, and OS. A larger trial is required to determine whether extended compared with limited LND leads to a small, but clinically relevant, survival difference (ClinicalTrials.gov NCT01215071).Patient summary
In this study, we investigated the outcome in bladder cancer patients undergoing cystectomy based on the anatomic extent of lymph node resection. We found that extended removal of lymph nodes did not reduce the rate of tumor recurrence in the expected range. 相似文献9.

Background
A role for local therapies including radical prostatectomy (RP) in prostate cancer (PCa) patients with clinical lymphadenopathies has been proposed. However, no data are available to identify men who would benefit from RP in this setting.Objective
To identify predictors of clinical recurrence (CR) in surgically managed PCa patients with clinical lymphadenopathies.Design, setting, and participants
We identified 162 patients with lymphadenopathies treated with RP and lymph node dissection at three referral centers.Outcome measures and statistical analyses
CR was defined as the onset of metastases detected by conventional imaging. Kaplan-Maier analyses assessed time to CR after stratifying patients according to the site of lymphadenopathies and nodal burden. Regression tree analysis stratified patients into risk groups on the basis of their preoperative characteristics.Results and limitations
Overall, 80% of patients had lymphadenopathies in the pelvis alone and 20% in the retroperitoneum ± pelvis. The median size of positive nodes was 13 mm. A total of 84 patients (52%) received neoadjuvant androgen deprivation therapy and 127 (78%) had pathological lymph node invasion. The median follow-up for survivors was 64 mo. The 8-yr CR-free and CSM-free survival rates were 59% and 80%, respectively. Biopsy grade group and preoperative nodal burden should identify patients more likely to experience CR. While <10% of men with biopsy grade group 1–3 and two or fewer clinical lymphadenopathies developed CR, up to 60% of patients with biopsy grade group 4–5 and retroperitoneal node involvement ultimately experienced CR at 8 yr after RP. The discrimination of the regression tree was 76% according to the area under the receiver operating characteristic curve. Our study is limited by potential unmeasured confounders and the relatively small sample size.Conclusions
Surgery in a multimodal setting might play a role in PCa patients with biopsy grade group 1–3 and/or enlarged nodes in the pelvis. Conversely, grade group 4–5 PCa and lymphadenopathies in the retroperitoneum are associated with worse oncologic outcomes.Patient summary
Approximately half of prostate cancer patients with clinical lymphadenopathies treated with radical prostatectomy are free from metastases at 8-yr follow-up. Radical prostatectomy with or without systemic therapies might play a role in selected patients with biopsy grade group 1–3 disease and/or enlarged nodes in the pelvis. Conversely, a higher grade group and the presence of lymphadenopathies in the retroperitoneum should identify candidates for systemic therapies upfront. 相似文献10.

Context
The Prostate Imaging-Reporting and Data System (PI-RADS) v2 analysis system for multiparametric magnetic resonance imaging (mpMRI) detection of prostate cancer (PCa) is based on PI-RADS v1, accumulated scientific evidence, and expert consensus opinion.Objective
To summarize the accuracy, strengths and weaknesses of PI-RADS v2, discuss pathway implications of its use and outline opportunities for improvements and future developments.Evidence acquisition
For this consensus expert opinion from the PI-RADS steering committee, clinical studies, systematic reviews, and professional guidelines for mpMRI PCa detection were evaluated. We focused on the performance characteristics of PI-RADS v2, comparing data to systems based on clinicoradiologic Likert scales and non–PI-RADS v2 imaging only. Evidence selections were based on high-quality, prospective, histologically verified data, with minimal patient selection and verifications biases.Evidence synthesis
It has been shown that the test performance of PI-RADS v2 in research and clinical practice retains higher accuracy over systematic transrectal ultrasound (TRUS) biopsies for PCa diagnosis. PI-RADS v2 fails to detect all cancers but does detect the majority of tumors capable of causing patient harm, which should not be missed. Test performance depends on the definition and prevalence of clinically significant disease. Good performance can be attained in practice when the quality of the diagnostic process can be assured, together with joint working of robustly trained radiologists and urologists, conducting biopsy procedures within multidisciplinary teams.Conclusions
It has been shown that the test performance of PI-RADS v2 in research and clinical practice is improved, retaining higher accuracy over systematic TRUS biopsies for PCa diagnosis.Patient summary
Multiparametric magnetic resonance imaging (MRI) and MRI-directed biopsies using the Prostate Imaging-Reporting and Data System improves the detection of prostate cancers likely to cause harm, and at the same time decreases the detection of disease that does not lead to harms if left untreated. The keys to success are high-quality imaging, reporting, and biopsies by radiologists and urologists working together in multidisciplinary teams. 相似文献11.

Purpose
The purpose of this study was to build and evaluate a high-performance algorithm to detect and characterize the presence of a meniscus tear on magnetic resonance imaging examination (MRI) of the knee.Material and methods
An algorithm was trained on a dataset of 1123 MR images of the knee. We separated the main task into three sub-tasks: first to detect the position of both horns, second to detect the presence of a tear, and last to determine the orientation of the tear. An algorithm based on fast-region convolutional neural network (CNN) and faster-region CNN, was developed to classify the tasks. The algorithm was thus used on a test dataset composed of 700 images for external validation. The performance metric was based on area under the curve (AUC) analysis for each task and a final weighted AUC encompassing the three tasks was calculated.Results
The use of our algorithm yielded an AUC of 0.92 for the detection of the position of the two meniscal horns, of 0.94 for the presence of a meniscal tear and of 083 for determining the orientation of the tear, resulting in a final weighted AUC of 0.90.Conclusion
We demonstrate that our algorithm based on fast-region CNN is able to detect meniscal tears and is a first step towards developing more end-to-end artificial intelligence-powered diagnostic tools. 相似文献12.

Purpose
This work presents our contribution to a data challenge organized by the French Radiology Society during the Journées Francophones de Radiologie in October 2018. This challenge consisted in classifying MR images of the knee with respect to the presence of tears in the knee menisci, on meniscal tear location, and meniscal tear orientation.Materials and methods
We trained a mask region-based convolutional neural network (R-CNN) to explicitly localize normal and torn menisci, made it more robust with ensemble aggregation, and cascaded it into a shallow ConvNet to classify the orientation of the tear.Results
Our approach predicted accurately tears in the database provided for the challenge. This strategy yielded a weighted AUC score of 0.906 for all three tasks, ranking first in this challenge.Conclusion
The extension of the database or the use of 3D data could contribute to further improve the performances especially for non-typical cases of extensively damaged menisci or multiple tears. 相似文献13.

OBJECTIVE
To compare the performance and discriminant properties of two instruments (a tree‐structured regression model and a logistic regression‐based nomogram), recently developed to predict lymph node invasion (LNI) at radical prostatectomy (RP), in a contemporary cohort of European patients.PATIENTS AND METHODS
The cohort comprised 1525 consecutive men treated with RP and bilateral pelvic LN dissection (PLND) in two tertiary academic centres in Europe. Clinical stage, pretreatment prostate‐specific antigen (PSA) level and biopsy Gleason sum were used to test the ability of the regression tree and the nomogram to predict LNI. Accuracy was quantified by the area under the receiver operating characteristic curve (AUC). All analyses were repeated for each participating institution.RESULTS
The AUC for the nomogram was 81%, vs 77% for the regression tree (P = 0.007). When data were stratified according to institution, the nomogram invariably had a higher AUC than the regression tree (Hamburg cohort: nomogram 82.1% vs regression tree 77.0%, P = 0.002; Milan cohort: 82.4% vs 75.9%, respectively; P = 0.03).CONCLUSIONS
Nomogram‐based predictions of LNI were more accurate than those derived from a regression tree; therefore, we recommend the use of nomogram‐derived predictions. 相似文献14.

Introduction
Horse racing is a hazardous sport. We analyzed the incidence and characteristics of jockey injuries in a typical horse race.Methods
We analyzed all injuries sustained by 224 jockeys in the last 72 years.Results
It was found that in 96.1% of the races there was at least one fall and in 28.6% of the races 50% or more of the jockeys fell. In 43.4% of the falls, the jockey was taken to the emergency room. Comparing the Palio with traditional races in other countries, a higher injury incidence rate was observed for every 100 falls (109.884 vs 27–59) and a lower concussion rate/100 falls (0.97 vs 1.8-7.4).Conclusion
The Palio is one of the most threatening races that continues today. Jockeys are at greater risk for a fall than any other race in the world. 相似文献15.

Background
There are little data regarding the morbidity of lymph node dissection (LND) for renal cell carcinoma (RCC) to assess its risk–benefit ratio.Objective
To evaluate the association of LND with 30-d complications among patients undergoing radical nephrectomy (RN) for RCC.Design, setting, and participants
A total of 2066 patients underwent RN for M0 or M1 RCC between 1990 and 2010, of whom 774 (37%) underwent LND.Intervention
RN with or without LND.Outcome measurements and statistical analysis
Associations of LND with 30-d complications were examined using logistic regression with several propensity score techniques. Extended LND, defined as removal of ≥13 lymph nodes, was examined in a sensitivity analysis.Results and limitations
A total of 184 (9%) patients were pN1 and 302 (15%) were M1. Thirty-day complications occurred in 194 (9%) patients, including Clavien grade ≥3 complications in 81 (4%) patients. Clinicopathologic features were well balanced after propensity score adjustment. In the overall cohort, LND was not statistically significantly associated with Clavien grade ≥3 complications, although there was an approximately 40% increased risk of any Clavien grade complication that did not reach statistical significance. Likewise, LND was not significantly associated with any Clavien grade or Clavien grade ≥3 complications when separately evaluated among M0 or M1 patients. Extended LND was not significantly associated with any Clavien grade or Clavien grade ≥3 complications. LND was not associated with length of stay or estimated blood loss. Limitations include a retrospective design.Conclusions
LND is not significantly associated with an increased risk of Clavien grade ≥3 complications, although it may be associated with a modestly increased risk of minor complications. In the absence of increased morbidity, LND may be justified in a predominantly staging role in the management of RCC.Patient summary
Lymph node dissection for renal cell carcinoma is not associated with increased rates of major complications. 相似文献16.

Objective
To assess whether even in the group of localized renal cell carcinoma (RCC), some patients might harbor a disease with a predilection for lymph node invasion (LNI) and/or lymph node (LN) progression and might deserve lymph node dissection (LND) at the time of surgery.Materials and methods
Between 1990 and 2014, 2,010 patients with clinically defined T1-T2N0M0 RCC were treated with nephrectomy and standardized LND at a single tertiary care referral center. The endpoint consists of the presence of LNI and/or nodal progression, defined as the onset of a new clinically detected lymphadenopathy (>10 mm) in the retroperitoneal lymphatic area with associated systemic progression or histological confirmation or both. We tested the association between clinical characteristics and the endpoint of interest. Predictors consisted of age at surgery, clinical tumor size, preoperative hemoglobin, and platelets levels. Multivariable logistic regression model and smoothed Lowess method were used.Results
LNI was recorded in 14 cases (2.2%). The median follow-up after surgery was 68 months. During the study period, 23 patients (1.1%) experienced LN progression; 91% of those patients experienced LN progression within 3 years after surgery. Combining the 2 endpoints, 36 patients (1.8%) had LNI and/or LN progression. Clinical tumor size was the only independent predictors of LNI and/or LN progression (OR = 1.25). A significant increase of the risk of LNI and/or LN progression was observed in RCC larger than 7 cm (cT2a or higher).Conclusions
LNI and/or LN progression is a rare entity in patients with localized RCC. Nonetheless, patients with larger tumors might still benefit from LND because of a non-negligible risk of LNI and/or LN progression. 相似文献17.

Introduction
The aim of this study is to assess the diagnostic value of the magnetic resonance imaging (MRI) in differentiating metastasic from non-metastatic lymph nodes in NSCLC patients compared with computed tomography (CT) and fluorodeoxyglucose (FDG) - positron emission tomography (PET) or both combined.Methods
Twenty-three studies (19 studies and 4 meta-analysis) with sample size ranging between 22 and 250 patients were included in this analysis. MRI, regardless of the sequence obtained, where used for the evaluation of N-staging of NSCLC. Histopathology results and clinical or imaging follow-up were used as the reference standard. Studies were excluded if the sample size was less than 20 cases, if less than 10 lymph nodes assessment were presented or studies where standard reference was not used. Papers not reporting sufficient data were also excluded.Results
As compared to CT and PET, MRI demonstrated a higher sensitivity, specificity and diagnostic accuracy in the diagnosis of metastatic or non-metastatic lymph nodes in N-staging in NSCLC patients. No study considered MRI inferior than conventional techniques (CT, PET or PET/CT). Other outstanding results of this review are fewer false positives with MRI in comparison with PET, their superiority over PET/CT to detect non-resectable lung cancer, to diagnosing infiltration of adjacent structures or brain metastasis and detecting small nodules.Conclusion
MRI has shown at least similar or better results in diagnostic accuracy to differentiate metastatic from non-metastatic mediastinal lymph nodes. This suggests that MRI could play a significant role in mediastinal NSCLC staging. 相似文献19.

Background
A fast, noninvasive test with high sensitivity (SN) and a negative predictive value (NPV), which is able to detect recurrences in bladder cancer (BC) patients, is needed. A newly developed urine assay, Xpert Bladder Cancer Monitor (Xpert), measures five mRNA targets (ABL1, CRH, IGF2, UPK1B, and ANXA10) that are frequently overexpressed in BC.Objective
To validate Xpert characteristics in patients previously diagnosed with non-muscle-invasive BC.Design, setting, and participants
Voided precystoscopy urine samples were prospectively collected at 22 sites. Xpert, cytology, and UroVysion were performed. If cystoscopy was suspicious for BC, a histologic examination was performed. Additionally, technical validation was performed and specificity was determined in patients without a history or clinical evidence of BC.Outcome measurements and statistical analysis
Test characteristics were calculated based on cystoscopy and histology results, and compared between Xpert, cytology, and UroVysion.Results and limitations
Of the eligible patients, 239 with a history of BC had results for all assays. The mean age was 71 yr; 190 patients were male, 53 never smoked, and 64% had previous intravesical immunotherapy (35%) or chemotherapy (29%). Forty-three cases of recurrences occurred. Xpert had overall SN of 74% (95% confidence interval [CI]: 60–85) and 83% (95% CI: 64–93) for high-grade (HG) tumors. The NPV was 93% (95% CI: 89–96) overall and 98% (95% CI: 94–99) for HG tumors. Specificity was 80% (95% CI: 73–85). Xpert SN and NPV were superior to those of cytology and UroVysion. Specificity in non-BC individuals (n = 508) was 95% (95% CI: 93–97).Conclusions
Xpert has an improved NPV compared with UroVysion and cytology in patients under follow-up for BC. It represents a promising tool for excluding BC in these patients, reducing the need for cystoscopy.Patient summary
Xpert is an easy-to-perform urine test with good performance compared with standard urine tests. It should help optimize the follow-up of recurrent bladder cancer patients. 相似文献20.
