Background
Guidelines advise multiparametric magnetic resonance imaging (mpMRI) before repeat biopsy in patients with negative systematic biopsy (SB) and a suspicion of prostate cancer (PCa), enabling MRI targeted biopsy (TB). No consensus exists regarding which of the three available techniques of TB should be preferred.Objective
To compare detection rates of overall PCa and clinically significant PCa (csPCa) for the three MRI-based TB techniques.Design, setting, and participants
Multicenter randomised controlled trial, including 665 men with prior negative SB and a persistent suspicion of PCa, conducted between 2014 and 2017 in two nonacademic teaching hospitals and an academic hospital.Intervention
All patients underwent 3-T mpMRI evaluated with Prostate Imaging Reporting and Data System (PIRADS) version 2. If imaging demonstrated PIRADS ≥3 lesions, patients were randomised 1:1:1 for one TB technique: MRI-transrectal ultrasound (TRUS) fusion TB (FUS-TB), cognitive registration TRUS TB (COG-TB), or in-bore MRI TB (MRI-TB).Outcome measurements and statistical analysis
Primary (overall PCa detection) and secondary (csPCa detection [Gleason score ≥3 + 4]) outcomes were compared using Pearson chi-square test.Results and limitations
On mpMRI, 234/665 (35%) patients had PIRADS ≥3 lesions and underwent TB. There were no significant differences in the detection rates of overall PCa (FUS-TB 49%, COG-TB 44%, MRI-TB 55%, p = 0.4). PCa detection rate differences were ?5% between FUS-TB and MRI-TB (p = 0.5, 95% confidence interval [CI] ?21% to 11%), 6% between FUS-TB and COG-TB (p = 0.5, 95% CI ?10% to 21%), and ?11% between COG-TB and MRI-TB (p = 0.17, 95% CI ?26% to 5%). There were no significant differences in the detection rates of csPCa (FUS-TB 34%, COG-TB 33%, MRI-TB 33%, p > 0.9). Differences in csPCa detection rates were 2% between FUS-TB and MRI-TB (p = 0.8, 95% CI ?13% to 16%), 1% between FUS-TB and COG-TB (p > 0.9, 95% CI ?14% to 16%), and 1% between COG-TB and MRI-TB (p > 0.9, 95% CI ?14% to 16%). The main study limitation was a low rate of PIRADS ≥3 lesions on mpMRI, causing underpowering for primary outcome.Conclusions
We found no significant differences in the detection rates of (cs)PCa among the three MRI-based TB techniques.Patient summary
In this study, we compared the detection rates of (aggressive) prostate cancer among men with prior negative biopsies and a persistent suspicion of cancer using three different techniques of targeted biopsy based on magnetic resonance imaging. We found no significant differences in the detection rates of (aggressive) prostate cancer among the three techniques. 相似文献2.

Background
Multiparametric magnetic resonance imaging (mpMRI)-targeted prostate biopsies can improve detection of clinically significant prostate cancer and decrease the overdetection of insignificant cancers. It is unknown whether visual-registration targeting is sufficient or augmentation with image-fusion software is needed.Objective
To assess concordance between the two methods.Design, setting, and participants
We conducted a blinded, within-person randomised, paired validating clinical trial. From 2014 to 2016, 141 men who had undergone a prior (positive or negative) transrectal ultrasound biopsy and had a discrete lesion on mpMRI (score 3–5) requiring targeted transperineal biopsy were enrolled at a UK academic hospital; 129 underwent both biopsy strategies and completed the study.Intervention
The order of performing biopsies using visual registration and a computer-assisted MRI/ultrasound image-fusion system (SmartTarget) on each patient was randomised. The equipment was reset between biopsy strategies to mitigate incorporation bias.Outcome measurements and statistical analysis
The proportion of clinically significant prostate cancer (primary outcome: Gleason pattern ≥3 + 4 = 7, maximum cancer core length ≥4 mm; secondary outcome: Gleason pattern ≥4 + 3 = 7, maximum cancer core length ≥6 mm) detected by each method was compared using McNemar's test of paired proportions.Results and limitations
The two strategies combined detected 93 clinically significant prostate cancers (72% of the cohort). Each strategy detected 80/93 (86%) of these cancers; each strategy identified 13 cases missed by the other. Three patients experienced adverse events related to biopsy (urinary retention, urinary tract infection, nausea, and vomiting). No difference in urinary symptoms, erectile function, or quality of life between baseline and follow-up (median 10.5 wk) was observed. The key limitations were lack of parallel-group randomisation and a limit on the number of targeted cores.Conclusions
Visual-registration and image-fusion targeting strategies combined had the highest detection rate for clinically significant cancers. Targeted prostate biopsy should be performed using both strategies together.Patient summary
We compared two prostate cancer biopsy strategies: visual registration and image fusion. A combination of the two strategies found the most clinically important cancers and should be used together whenever targeted biopsy is being performed. 相似文献3.

Background
There is growing interest to implement multiparametric magnetic resonance imaging (mpMRI) and MR-guided biopsy (MRGB) for biopsy-naïve men with suspected prostate cancer.Objective
Primary objective was to compare and evaluate an MRI pathway and a transrectal ultrasound-guided biopsy (TRUSGB) pathway in biopsy-naïve men with prostate-specific antigen levels of ≥3 ng/ml.Design, setting, and population
A prospective, multicenter, powered, comparative effectiveness study included 626 biopsy-naïve patients (from February 2015 to February 2018).Intervention
All patients underwent prebiopsy mpMRI followed by systematic TRUSGB. Men with suspicious lesions on mpMRI also underwent MRGB prior to TRUSGB. MRGB was performed using the in-bore approach.Outcome measurements and statistical analysis
Clinically significant prostate cancer (csPCa) was defined as grade group ≥2 (Gleason score ≥3 + 4) in any core. The main secondary objectives were the number of men who could avoid biopsy after nonsuspicious mpMRI, the number of biopsy cores taken, and oncologic follow-up. Differences in proportions were tested using McNemar's test with adjusted Wald confidence intervals for differences of proportions with matched pairs.Results and limitations
The MRI pathway detected csPCa in 159/626 (25%) patients and insignificant prostate cancer (insignPCa) in 88/626 patients (14%). TRUSGB detected csPCa in 146/626 patients (23%) and insignPCa in 155/626 patients (25%). Relative sensitivity of the MRI pathway versus the TRUSGB pathway was 1.09 for csPCa (p = 0.17) and 0.57 for insignPCa (p < 0.0001). The total number of biopsy cores reduced from 7512 to 849 (–89%). The MRI pathway enabled biopsy avoidance in 309/626 (49%) patients due to nonsuspicious mpMRI. Immediate TRUSGB detected csPCa in only 3% (10/309) of these patients, increasing to 4% (13/309) with 1-yr follow-up. At the same time, TRUSGB would overdetect insignPCa in 20% (63/309). “Focal saturation” by four additional perilesional cores to MRGB improved the detection of csPCa in 21/317 (7%) patients. Compared with the literature, our proportion of nonsuspicious mpMRI cases is significantly higher (27–36% vs 49%) and that of equivocal cases is lower (15–28% vs 6%). This is probably due to the high-quality standard in this study. Therefore, a limitation is the duplication of these results in less experienced centers.Conclusions
In biopsy-naïve men, the MRI pathway compared with the TRUSGB pathway results in an identical detection rate of csPCa, with significantly fewer insignPCa cases. In this high-quality standard study, almost half of men have nonsuspicious MRI, which is higher compared with other studies. Not performing TRUS biopsy is at the cost of missing csPCa only in 4%.Patient summary
We compared magnetic resonance imaging (MRI) with MRI-guided biopsy against standard transrectal ultrasound biopsy for the diagnosis of prostate cancer in biopsy-naïve men. Our results show that patients can benefit from MRI because biopsy may be omitted in half of men, and fewer indolent cancers are detected, without compromising the detection of harmful disease. Men also need fewer needles to make a diagnosis. 相似文献4.

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5.

Background
Understanding physician-level discrepancies is increasingly a target of US healthcare reform for the delivery of quality-focused patient care.Objective
To estimate the relative contributions of patient and surgeon characteristics to the variability in key outcomes after partial nephrectomy (PN).Design, setting, and participants
Retrospective review of 1461 patients undergoing PN performed by 19 surgeons between 2011 and 2016 at a tertiary care referral center.Intervention
PN for a renal mass.Outcomes measurements and statistical analysis
Hierarchical linear and logistic regression models were built to determine the percentage variability contributed by fixed patient and surgeon factors on peri- and postoperative outcomes. Residual between- and within-surgeon variability was calculated while adjusting for fixed factors.Results and limitations
On null hierarchical models, there was significant between-surgeon variability in operative time, estimated blood loss (EBL), ischemia time, excisional volume loss, length of stay, positive margins, Clavien complications, and 30-d readmission rate (all p < 0.001), but not chronic kidney disease upstaging (p = 0.47) or percentage preservation of glomerular filtration rate (p = 0.49). Patient factors explained 82% of the variability in excisional volume loss and 0–32% of the variability in the remainder of outcomes. Quantifiable surgeon factors explained modest amounts (10–40%) of variability in intraoperative outcomes, and noteworthy amounts of variability (90–100%) in margin rates and patient morbidity outcomes. Immeasurable surgeon factors explained the residual variability in operative time (27%), EBL (6%), and ischemia time (31%).Conclusions
There is significant between-surgeon variability in outcomes after PN, even after adjusting for patient characteristics. While renal functional outcomes are consistent across surgeons, measured and unmeasured surgeon factors account for 18–100% of variability of the remaining peri- and postoperative variables. With the increasing utilization of value-based medicine, this has important implications for the goal of optimizing patient care.Patient summary
We reviewed our institutional database on partial nephrectomy performed for renal cancer. We found significant variability between surgeons for key outcomes after the intervention, even after adjusting for patient characteristics. 相似文献6.

Background
Some studies suggest that gonadotropin-releasing hormone (GnRH) agonists are associated with higher risk of adverse events than antiandrogens (AAs) monotherapy. However, it has been unclear whether this is due to indication bias.Objective
To investigate rates of change in comorbidity for men on GnRH agonists versus AA monotherapy in a population-based register study.Design, setting, and participants
Men with advanced nonmetastatic prostate cancer (PCa) who received primary AA (n = 2078) or GnRH agonists (n = 4878) and age- and area-matched PCa-free men were selected from Prostate Cancer Database Sweden 3.0. Increases in comorbidity were measured using the Charlson Comorbidity Index (CCI), from 5 yr before through to 5 yr after starting androgen deprivation therapy (ADT).Outcome measures and statistical methods
Multivariable linear regression was used to determine differences in excess rate of CCI change before and after ADT initiation. Risk of any incremental change in CCI following ADT was assessed using multivariable Cox regression analyses.Results and limitations
Men on GnRH agonists experienced a greater difference in excess rate of CCI change after starting ADT than men on AA monotherapy (5.6% per yr, p < 0.001). Risk of any new CCI change after ADT was greater for GnRH agonists than for AA (hazard ratio, 1.32; 95% confidence interval, 1.20–1.44).Conclusions
Impact on comorbidity was lower for men on AA monotherapy than for men on GnRH agonists. Our results should be confirmed through randomised trials of effectiveness and adverse effects, comparing AA monotherapy and GnRH agonists in men with advanced nonmetastatic PCa who are unsuitable for curative treatment.Patient summary
Hormone therapies for advanced prostate cancer can increase the risk of other diseases (eg, heart disease, diabetes). This study compared two common forms of hormone therapy and found that the risk of another serious disease was higher for those on gonadotropin-releasing hormone agonists than for those on antiandrogen monotherapy. 相似文献7.

Background
The study aims at comparing the bony anatomy of the syndesmosis in patients who sustained a high fibular fracture with syndesmosis disruption and that of the non-injured population. We hypothesised that there are certain anatomical features making the syndesmosis susceptible to injury.Methods
The CT examinations of 75 patients who sustained a high fibular fracture with syndesmosis disruption and control group of 75 patients with unrelated foot problems were compared. The depth, fibular engagement and rotational orientation of the tibial incisura were analyzed.Results
With the median values of the control group as cutoff there were 71% shallow, 71% disengaged and 77% retroverted syndesmoses in the injury group. The differences between the groups were statistically significant for every measure (P < .002 to P > .0001).Conclusions
Patients with a shallow, disengaged and retroverted bony configuration of the syndesmosis are overrepresented among patients with syndesmosis disruption. 相似文献8.

Background
There are limited data examining the risk of prostate cancer (PCa) in patients with inflammatory bowel disease (IBD).Objective
To compare the incidence of PCa between men with and those without IBD.Design, setting, and participants
This was a retrospective, matched-cohort study involving a single academic medical center and conducted from 1996 to 2017. Male patients with IBD (cases = 1033) were randomly matched 1:9 by age and race to men without IBD (controls = 9306). All patients had undergone at least one prostate-specific antigen (PSA) screening test.Outcome measurements and statistical analysis
Kaplan-Meier and multivariable Cox proportional hazard models, stratified by age and race, evaluated the relationship between IBD and the incidence of any PCa and clinically significant PCa (Gleason grade group ≥2). A mixed-effect regression model assessed the association of IBD with PSA level.Results and limitations
PCa incidence at 10 yr was 4.4% among men with IBD and 0.65% among controls (hazard ratio [HR] 4.84 [3.34–7.02] [3.19–6.69], p < 0.001). Clinically significant PCa incidence at 10 yr was 2.4% for men with IBD and 0.42% for controls (HR 4.04 [2.52–6.48], p < 0.001). After approximately age 60, PSA values were higher among patients with IBD (fixed-effect interaction of age and patient group: p = 0.004). Results are limited by the retrospective nature of the analysis and lack of external validity.Conclusions
Men with IBD had higher rates of clinically significant PCa when compared with age- and race-matched controls.Patient summary
This study of over 10 000 men treated at a large medical center suggests that men with inflammatory bowel disease may be at a higher risk of prostate cancer than the general population. 相似文献9.

Background
The number of screws used for sliding calcaneal osteotomy fixation has not been examined in the literature. The purpose of this paper is to examine this topic.Methods
Retrospective chart review was performed on 190 patients who met selection criteria. We compared complication risk for single versus double screw, headed versus headless screw, and short versus longitudinal incision cases.Results
The mean age was 48.4 (18–83) years and average follow up was 28 (12–150) weeks. All cases achieved radiographic union. Overall complication rate was 19.5% (37/190). Risk of complication did not differ significantly between single and double screw (RR: 1.170; 95% CI: 0.66–2.09; p = 0.594) or short and extended incision groups (RR: 0.868; 95% CI: 0.42–1.80; p = 0.704). Risk of complication differed significantly between headed and headless screw fixation (RR: 5.558; 95% CI: 2.69–11.50; p < 0.0001).Conclusions
Single screw fixation of sliding calcaneal osteotomy achieves similar outcomes as double screw fixation. Headless screws are advantageous for minimizing hardware pain and subsequent hardware removal. 相似文献10.

Background
This study was performed to evaluate the intermediate-term clinical outcomes after proximal chevron osteotomy for hallux valgus in patients with generalized ligamentous laxity, and to determine the effect on postoperative recurrence of deformity.Methods
There were 23 cases in laxity group (Beighton score ≥5 points) and 175 in non-laxity group with a mean followup of 46.3 months. Clinical evaluation consisted of the AOFAS score, Foot and Ankle Ability Measure (FAAM), and radiographic measurement of hallux alignment. Risk factors associated with postoperative recurrence were evaluated using univariate analysis.Results
Recurrence rates were 21.7% in the laxity group and 17.1% in non-laxity group (P = .218). There were no significant differences in clinical and radiographic measurements at final followup between the 2 groups. Preoperative HVA and IMA were found to be predictive factors of recurrence (OR = 6.3, 4.2; P = .001, .018, respectively).Conclusion
There were no statistical differences in the clinical and radiographic outcomes between hallux valgus with and without generalized ligamentous laxity. Generalized ligamentous laxity demonstrated no definitive effects on postoperative recurrence of hallux valgus deformity. 相似文献11.

Background
Non–muscle-invasive bladder cancer (NMIBC) has a significant risk of recurrence despite adjuvant intravesical therapy.Objective
To determine whether celecoxib, a cyclo-oxygenase 2 inhibitor, reduces the risk of recurrence in NMIBC patients receiving standard treatment.Design, setting, and participants
BOXIT (CRUK/07/004, ISRCTN84681538) is a double-blinded, phase III, randomised controlled trial. Patients aged ≥18 yr with intermediate- or high-risk NMIBC were accrued across 51 UK centres between 1 November 2007 and 23 July 2012.Intervention
Patients were randomised (1:1) to celecoxib 200 mg twice daily or placebo for 2 yr. Patients with intermediate-risk NMIBC were recommended to receive six weekly mitomycin C instillations; high-risk NMIBC cases received six weekly bacillus Calmette-Guérin and maintenance therapy.Outcome measurements and statistical analysis
The primary endpoint was time to disease recurrence. Analysis was by intention to treat.Results and limitations
A total of 472 patients were randomised (236:236). With median follow-up of 44 mo (interquartile range: 36–57), 3-yr recurrence-free rate (95% confidence interval) was as follows: celecoxib 68% (61–74%) versus placebo 64% (57–70%; hazard ratio [HR] 0.82 [0.60–1.12], p = 0.2). There was no difference in high-risk (HR 0.77 [0.52–1.15], p = 0.2) or intermediate-risk (HR 0.90 [0.55–1.48], p = 0.7) NMIBC. Subgroup analysis suggested that time to recurrence was longer in pT1 NMIBC patients treated with celecoxib compared with those receiving placebo (HR 0.53 [0.30–0.94], interaction test p = 0.04). The 3-yr progression rates in high-risk patients were low: 10% (6.5–17%) and 9.7% (6.0–15%) in celecoxib and placebo arms, respectively. Incidence of serious cardiovascular events was higher in celecoxib (5.2%) than in placebo (1.7%) group (difference +3.4% [–0.3% to 7.2%], p = 0.07).Conclusions
BOXIT did not show that celecoxib reduces the risk of recurrence in intermediate- or high-risk NMIBC, although celecoxib was associated with delayed time to recurrence in pT1 NMIBC patients. The increased risk of cardiovascular events does not support the use of celecoxib.Patient summary
Celecoxib was not shown to reduce the risk of recurrence in intermediate- or high-risk non–muscle-invasive bladder cancer (NMIBC), although celecoxib was associated with delayed time to recurrence in pT1 NMIBC patients. The increased risk of cardiovascular events does not support the use of celecoxib. 相似文献12.

Background
Periprosthetic cystic osteolysis is a well-known complication of total ankle replacement. Several theories have been proposed for its aetiology, based on individual biomechanical, radiological, histopathology and outcome studies.Methods
Studies that met predefined inclusion/exclusion criteria were analysed to identify literature describing the presence of peri-prosthetic ankle cystic osteolysis. Quantitative data from the selected articles were combined and statistically tested in order to analyse possible relations between ankle peri-prosthetic bone cysts and specific implant characteristics.Results
Twenty-one articles were elected, totalizing 2430 total ankle replacements, where 430 developed peri-prosthetic cystic osteolysis.A statistically significant association (P < .001) was found between the presence of bone cysts and non-anatomic implant configuration, hydroxyapatite-coating, mobile-bearing and non tibial-stemmed implants. No significant association existed between the type of constraining and the presence of cysts (P > .05).Conclusions
Non-anatomic, mobile-bearing, hydroxyapatite-coated and non tibial-stemmed total ankle replacements are positively associated with more periprosthetic bone cysts. 相似文献13.

Background
Total ankle replacement (TAR) represents an alternative to fusion for the treatment of end-stage ankle osteoarthritis. The aim of the present study was to retrospectively assess the frequency of infections between TARs with anterior and lateral transfibular approach at 12-months follow-up.Methods
81 TARs through an anterior approach and 69 TARs through a lateral approach were performed between May 2011 and July 2015. We compared surgical time and tourniquet time, as well as superficial and deep infections frequency during the first 12 postoperative months.Results
In the anterior approach group, there were 3 (3.7%) deep infections and 4 (4.9%) superficial wound infections. In the lateral approach group, there were 1 (1.4%) deep infection and 2 superficial wound infections (2.9%). There were not statistically significant differences between the groups. There was a significant difference between anterior approach (115 minutes) and lateral approach group (179 minutes) in terms of surgical time (P < 0.001).Conclusions
The frequency of superficial and deep periprosthetic infections during the first postoperative year was not significantly different in the lateral approach group compared to the anterior approach group, despite the significantly longer surgical time in the lateral transfibular approach group. 相似文献14.

Background
Mutations in DNA repair genes are associated with aggressive prostate cancer (PCa).Objective
To assess whether germline mutations are associated with grade reclassification (GR) in patients undergoing active surveillance (AS).Design, setting, and participants
Two independent cohorts of PCa patients undergoing AS; 882 and 329 patients from Johns Hopkins and North Shore, respectively.Outcome measurements and statistical analysis
Germline DNA was sequenced for DNA repair genes, including BRCA1/2 and ATM (three-gene panel). Pathogenicity of mutations was defined according to the American College of Medical Genetics guidelines. Association of mutation carrier status and GR was evaluated by a competing risk analysis.Results and limitations
Of 1211, 289 patients experienced GR; 11 of 26 with mutations in a three-gene panel and 278 of 1185 noncarriers; adjusted hazard ratio (HR) = 1.96 (95% confidence interval [CI] = 1.004–3.84, p = 0.04). Reclassification occurred in six of 11 carriers of BRCA2 mutations and 283 of 1200 noncarriers; adjusted HR = 2.74 (95% CI = 1.26–5.96, p = 0.01). The carrier rates of pathogenic mutations in the three-gene panel, and BRCA2 alone, were significantly higher in those reclassified (3.8% and 2.1%, respectively) than in those not reclassified (1.6% and 0.5%, respectively; p = 0.04 and 0.03, respectively). Carrier rates for BRCA2 were greater for those reclassified from Gleason score (GS) 3 + 3 at diagnosis to GS ≥4 + 3 (4.1% vs 0.7%, p = 0.01) versus GS 3 + 4 (2.1% vs 0.6%; p = 0.03). Results are limited by the small number of mutation carriers and an intermediate end point.Conclusions
Mutation status of BRCA1/2 and ATM is associated with GR among men undergoing AS.Patient summary
Men on active surveillance with inherited mutations in BRCA1/2 and ATM are more likely to harbor aggressive prostate cancer. 相似文献15.

Introduction and objective
One of the inherent features of kidney tumours is the capacity to spread inside the venous system as tumour thrombi. The aim of this study was to assess in patients with stage pT3apN0cM0 kidney cancer whether venous tumour involvement influenced tumour recurrence.Materials and methods
A retrospective analysis of patients with stage pT3apN0cM0 kidney cancer treated with radical nephrectomy between 1990-2015. Univariate and multivariate Cox regression analysis to identify predictive variables and independent predictive variables relating to recurrence.Results
The results of 153 patients were studied. The median follow-up was 82 (IQR 36-117) months. Recurrence-free survival at 5 years was 58.9% with a median of 97 (95% CI 49.9-144.1) months. Seventy-seven (50.3%) patients recurred. Seventy cases 70 (90.9%) had distant metastases, 17 (14.2%) of these patients had local recurrence in the bed of nephrectomy. Tumour necrosis (p = .0001), and microvascular invasion (p = .001) were identified as independent predictors of tumour recurrence in the multivariable analysis.Conclusions
In our series, after multivariable analysis, venous tumour extension was not related to recurrence. Tumour necrosis and microvascular infiltration did behave as independent predictive factors of tumour recurrence. 相似文献16.

Introduction
Acute respiratory distress syndrome (ARDS) is a complication that affects approximately 40% of burn patients and is associated with high mortality rates. Extracorporeal membrane oxygenation (ECMO) therapy is a management option for severe refractory hypoxemic respiratory failure; however, there is little literature reporting the effectiveness of this therapy in burns. Our study objective was to review patient outcomes in burns following severe ARDS treated with ECMO.Methods
We retrospectively reviewed all patients treated with ECMO for ARDS who received their burn care at a single regional burn center between 9/1/2006 and 8/31/2016. Primary patient outcome examined was discharge disposition.Results
We identified 8 patients who had ARDS secondary to burn who were placed onto ECMO during this 10-year period. The average APACHE score, SOFA score, and P/F ratio were 21 ± 3, 9 ± 2, and 59 ± 8, respectively, at the time of decision for ECMO. No ECMO-related complications were identified. Out of the 8 patients reviewed, 1 died, 4 were discharged to acute rehabilitation or a long-term acute care facility, and 3 were discharged to home.Conclusion
Mortality in burn patients with ARDS who are managed with ECMO is extremely low. Careful selection and timely intervention with ECMO contributed to good clinical outcomes. 相似文献17.

Background
Anatomic graft reconstruction of the anterior talo-fibular ligament is an alternative for patients who are bad candidates for standard procedures such as a Broström–Gould reconstruction (high-demand athletes, obesity, hyperlaxity or collagen disorders, capsular insufficiency or talar avulsions). The purpose of this study is to describe an all-inside arthroscopic technique for ATFL reconstruction, and the results in a series of patients with chronic ankle instability.Methods
We reviewed patients with chronic ATFL ruptures treated with an all-inside arthroscopic allograft reconstruction of the ATFL, with a minimum 2-year follow-up. Twenty-two patients with lateral ankle instability were included. Mean follow-up was 34 ± 2.5 months.Results
The mean AOFAS score improved from 62.3 ± 6.7 points preoperatively to 97.2 ± 3.2 points at final follow-up. Three patients suffered complications: one case each of ankle rigidity, superficial peroneal nerve injury and fibular fracture.Conclusions
Chronic ATFL injuries are amenable to all-inside arthroscopic allograft reconstruction fixed with tenodesis screws. This procedure simplifies other reported techniques in that it facilitates identification and bone tunnel placement of the talar ATFL insertion. 相似文献18.

Background
We report our experience with the Minimally Invasive Chevron Akin (MICA) technique for correcting hallux valgus, and evaluate its effectiveness and associated complications.Methods
Case series of 13 feet with mild to moderate symptomatic hallux valgus treated surgically from July 2013 to December 2014, with at least 48-months follow-up. Patients were assessed pre-operatively and post-operatively with radiographical measurements (Hallux Valgus Angle (HVA) and Intermetatarsal Angle (IMA)) and clinical scores (American Orthopaedic Foot and Ankle Society (AOFAS), 36-Item Short Form Health Survery (SF-36), Visual Analog Scale (VAS)).Results
Mean HVA and IMA decreased from 30.4° and 13.9°–10.9° and 10.2° respectively (p < 0.05). The mean AOFAS score improved from an average of 59.0–93.7 (p < 0.05). All patients reported a VAS score of 0 post-operatively, and the 4 SF-36 domains improved significantly (p < 0.05).Conclusions
The MICA technique is a safe and effective method in the surgical correction of mild to moderate hallux valgus deformity, and continued use is justified. 相似文献19.
