Accurate recurrence risk assessment in hormone receptor positive, HER2/neu negative breast cancer is critical to plan precise therapy. CanAssist Breast (CAB) assesses recurrence risk based on tumor biology using artificial intelligence-based approach. We report CAB risk assessment correlating with disease outcomes in multiple clinically high- and low-risk subgroups. In this retrospective cohort of 925 patients [median age-54 (22–86)] CAB had hazard ratio (HR) of 3 (1.83–5.21) and 2.5 (1.45–4.29), P = 0.0009) in univariate and multivariate analysis. CAB's HR in sub-groups with the other determinants of outcome, T2 (HR: 2.79 (1.49–5.25), P = 0.0001); age [< 50 (HR: 3.14 (1.39–7), P = 0.0008)]. Besides application in node-negative patients, CAB's HR was 2.45 (1.34–4.47), P = 0.0023) in node-positive patients. In clinically low-risk patients (N0 tumors up to 5 cms) (HR: 2.48 (0.79–7.8), P = 0.03) and with luminal-A characteristics (HR: 4.54 (1–19.75), P = 0.004), CAB identified >16% as high-risk with recurrence rates of up to 12%. In clinically high-risk patients (T2N1 tumors (HR: 2.65 (1.31–5.36), P = 0.003; low-risk DMFS: 92.66 ± 1.88) and in women with luminal-B characteristics (HR: 3.24; (1.69–6.22), P < 0.0001; low-risk DMFS: 93.34 ± 1.34)), CAB identified >64% as low-risk. Thus, CAB prognostication was significant in women with clinically low- and high-risk disease. The data imply the use of CAB for providing helpful information to stratify tumors based on biology incorporated with clinical features for Indian patients, which can be extrapolated to regions with similarly characterized patients, South-East Asia. 相似文献

AimThis study aimed to evaluate the course of bone and mineral metabolism after liver transplantation (LT) in patients with chronic liver disease.MethodsOne hundred four patients who had undergone LT and had a minimum of 6 months of follow-up after LT were included in this prospective cohort study. The following parameters were evaluated for each patient: preoperative and postoperative (postoperative day [POD]30, POD90, POD180) osteocalcin, bone-specific alkaline phosphatase (BALP), type 1 collagen, beta-C-terminal end telopeptide (β-CTx), vitamin D, parathyroid hormone (PTH), ALP, calcium, phosphate, sedimentation, and bone mineral densitometer scores (L2, L4, L total, and F total). The parameters were compared in terms of sex, presence of liver tumor (hepatocellular carcinoma [HCC; n = 19] vs non-HCC [n = 85]), and presence of autoimmune liver disease (autoimmune liver disease [ALD; n = 8] vs non-ALD [n = 96]).ResultsThe median age of the patients (n = 81 men and n = 23 women) was 52 years (95% CI, 50-56). There was a significant change in the defined time intervals in parameters such as osteocalcin (P < .001), BALP (P < .001), β-CTx (P < .001), vitamin D (P < .001), PTH (P < .001), ALP (P = .001), calcium (P < .001), phosphate (P = .001), L2 (P = .038), L total (P = .026), and F total (P < .001) scores. There was a significant difference in POD90 ALP (P = .033), POD180 calcium (P = .011), POD180 phosphate (P = .011), preoperative sedimentation (P = .032), and POD180 F total (P = .013) scores between both sexes. There was a significant difference in POD180 osteocalcin (P = .023), POD180 β-CTx (P = .017), and preOP calcium (P = .003) among the HCC and non-HCC groups. Furthermore, we found significant differences in preoperative ALP (P = .008), preoperative sedimentation (P = .019), POD90 (P = .037) and POD180 L2 (P = .005) scores, preoperative (P = .049) and POD180 L4 (P = .017), and POD180 L total (P = .010) and F total (P = .022) scores between the patients with and without ALD.ConclusionThis study shows that the bone and mineral metabolism of the LT recipients was negatively affected after LT. In addition, we showed that bone and mineral metabolism was more prominent in patients with HCC, and bone mineral density scores were higher in patients with ALD. 相似文献

Background
Obesity has historically been a positive predictor of surgical morbidity, especially in the morbidly obese. The purpose of our study was to compare outcomes of obese patients undergoing laparoscopic cholecystectomy (LC).Methods
We reviewed 1382 consecutive patients retrospectively who underwent LC for various pathologies from January 2008 to August 2011. Patients were stratified based on the World Health Organization definitions of obesity: nonobese (body mass index [BMI] < 30 kg/m2), obesity class I (BMI 30–34.9 kg/m2), obesity class II (BMI 35–39.9 kg/m2), and obesity class III (BMI ≥ 40 kg/m2). The primary end points were conversion rates and surgical morbidity. The secondary end point was length of stay.Results
There were significantly more females in the obesity II and III groups (P = 0.0002). American Society of Anesthesiologists scores were significantly higher in the obesity I, II, and III groups compared with the nonobese (P < 0.05; P < 0.01; and P < 0.0001, respectively). Independent predictors of conversion on multivariate analysis (MVA) included age (P = 0.01), acute cholecystitis (P = 0.03), operative time (P < 0.0001), blood loss (P < 0.0001), and fellowship-trained surgeons (P < 0.0001). Independent predictors of intraoperative complications on MVA included age (P = 0.009), white patients (P = 0.009), previous surgery (P = 0.001), operative time (P < 0.0001), and blood loss (P = 0.01). Independent predictors of postoperative complications on MVA included American Society of Anesthesiologists score (P < 0.0001), acute cholecystitis (P < 0.0001), and a postoperative complication (P < 0.0001). BMI was not a predictor of conversions or surgical morbidity. Length of stay was not significantly different between the four groups.Conclusions
This study demonstrates that overall conversion rates and surgical morbidity are relatively low following LC, even in obese and morbidly obese patients. 相似文献4.

BackgroundLiterature regarding total knee arthroplasty (TKA) outcomes in sickle cell disease (SCD) is limited. Moreover, 10-year survivorship of SCD implants is unknown. This study aimed to observe 10-year cumulative incidence and indications for revision TKA in patients who did and did not have SCD.MethodsPatients who underwent primary TKA were identified using a large national database. The SCD patients were matched by age, sex, and a comorbidity index to a control cohort in a 1:4 ratio. The 10-year cumulative incidence rates were determined using Kaplan–Meier survival analyses. Multivariable analyses were conducted using Cox proportional hazard modeling. Chi-squared analyses were conducted to compare indications for revision between cohorts. In total, 1,010 SCD patients were identified, 100,000 patients included in the unmatched control, and 4,020 patients included in the matched control.ResultsCompared to the unmatched control cohort, SCD patients exhibited higher 10-year all-cause revision (HR: 1.86; P < .001) with higher proportions of revisions for periprosthetic joint infection (PJI) (P < .001), aseptic loosening (P < .001), and hematoma (P < .001). Compared to the matched control, SCD patients had higher 10-year all-cause revision (Hazard Ratio (HR): 1.39; P = .034) with a higher proportion of revisions for PJI (P = .044), aseptic loosening (P = .003), and hematoma (P = .019).ConclusionIndependent of other comorbidities, SCD patients are more likely to undergo revisions for PJI, aseptic loosening, and hematoma compared to patients who do not have SCD. Due to the high-risk of these complications, perioperative and postoperative surgical optimization should be enforced in SCD patients. 相似文献

PurposeTo use pathologic indicators to determine which patients benefit from postmastectomy radiation therapy (PMRT) for breast cancer after neoadjuvant chemotherapy (NACT) and total mastectomy (TM).Patients and methodsWe enrolled 4236 patients with breast invasive ductal carcinoma who received NACT followed by TM. Cox regression analysis was used to calculate hazard ratios (HRs) and confidence intervals; independent predictors were controlled for or stratified in the analysis.ResultsAfter multivariate Cox regression analyses, the adjusted HRs derived for PMRT for all-cause mortality were 0.65 (0.52–0.81, P < 0.0001) and 0.58 (0.47–0.71, P < 0.0001) in postchemotherapy pathologic tumor stages T2–4 (ypT3–4) and postchemotherapy pathologic nodal stages N2–3 (ypN2–3), respectively. Moreover, adjusted HRs derived for PMRT with all-cause mortality were 0.51 (0.38–0.69, P < 0.0001), 0.60 (0.40–0.88, P = 0.0096), and 0.64 (0.48–0.86, P = 0.0024) in pathological stages IIIA, IIIB, and IIIC, respectively. Additionally, the PMRT group showed significant locoregional control irrespective of the pathologic response, even ypT0, ypN0, or pathological complete response (pCR), compared with the No-PMRT group. The multivariate analysis showed no statistical differences between the PMRT and No-PMRT groups for distant metastasis-free survival in any pathologic response of ypT0–4, ypN0–3, and pathologic American Joint Committee on Cancer stages pCR to IIIC.ConclusionFor patients with breast cancer ypT3–4, ypN2–3, or pathologic stages IIIA–IIIC receiving NACT and TM, benefit from PMRT if it is associated with OS benefits, regardless of the clinical stage of the disease. Compared with No-PMRT, PMRT improved locoregional recurrence-free survival, even pCR, in patients with breast cancer receiving NACT and TM. 相似文献

BackgroundThe common causes of subaortic left ventricular outflow tract obstruction (LVOTO) are hypertrophic cardiomyopathy (HCM) and membranous/tunnel subaortic stenosis (SAS). Reoperation after corrective surgery may be due to recurrent disease, associated congenital defects, or complications of the initial procedure. This study compares the late outcomes of young patients with HCM and SAS.MethodsWe studied clinical, echocardiographic, and operative data of patients ≤21 years of age at the time of surgery for LVOTO between August 1963 and August 2018. We stratified patients into HCM (n = 152) and congenital SAS (n = 63) groups and compared survival and cumulative incidence of reoperation.ResultsAt initial repair, patients with HCM were older than patients with SAS (median [interquartile range] age, 15 [10-19] years vs 8 [5-13] years; P < .001), and patients with HCM were more symptomatic with dyspnea (P < .001), chest pain (P = .002), and presyncope/syncope (P = .005). Thirty-day mortality was 1.3% vs 0% for HCM and SAS groups. During a median follow-up of 13.1 years, survival was similar through the first 10 years; but during the second decade, patients with HCM had poorer survival (survival at 20 years, 80% vs 91% for patients with SAS; P = .007). Ten years after repair, reoperation for recurrent LVOTO was performed in 5% of patients with HCM vs 31% in those with SAS (P < .001).ConclusionsIn this surgical cohort, patients with HCM were more symptomatic preoperatively than those with SAS. Late survival of patients with SAS was superior to that of patients with HCM despite a greater need for reoperation. 相似文献

AimThis study aims to validate Japanese diagnostic criteria for acute-on-chronic liver failure (ACLF) and confirm the feasibility of performing transplantation.MethodsWe included 60 patients with acute liver injury. Demographic and clinical features were retrospectively collected, and the primary outcome was compared among 4 types: acute liver failure (ALF) with hepatic coma (n = 23), ALF without hepatic coma (n = 12), acute liver injury (n = 20), and ACLF (n = 5). Moreover, 80 transplanted patients were enrolled to compare the difficulty of transplantation between ALF (n = 8) vs non-ALF (n = 72) patients.ResultsSeven patients in the ALF with hepatic coma group and 1 patient in the ACLF with hepatic coma group were transplanted. Ten patients who could not be registered for transplantation died. In univariate analysis, liver failure type (P < .0001), total bilirubin level (P = .05), and prothrombin time internationalized ratio (P < .0001) were associated with patient survival. In multivariate analysis, liver failure type was associated with patient survival (P < .0001). The respective 1-, 3-, and 5-year patient survival rates were 45.9%, 45.9%, and 45.9% for ALF patients with hepatic coma; 100.0%, 100.0%, and 100.0% for ALF patients without hepatic coma and acute liver injury; and 80.0%, 80.0%, and 80.0% for ACLF patients (P < .0001). Chronic liver disease did not affect operation time (P = .46) and bleeding volume (P = .49).ConclusionPatients diagnosed with ACLF via Japanese criteria presented significantly higher survival rates than ALF patients with hepatic coma. 相似文献

ObjectivesTo examine the effect of extragonadal tumor site on the risk for cardiovascular, hematopoietic malignancies, and solid cancer-related causes of death.Patients and methodsMale patients diagnosed with germ cell tumors (GCTs) between 1973 and 2008 were identified from the Surveillance, Epidemiology and End Results database, and stratified by the site of primary cancer (mediastinal and nonmediastinal extragonadal vs. gonadal). Using competing risk analysis restricted to events that happened at least 5 years after diagnosis, we examined the possible effect of primary tumor site on the risk for death related to hematopoietic malignancies, cardiovascular disorders, and solid cancers in the study cohort.ResultsOf 37,283 patients included in our analysis, 17,715 were diagnosed with nonseminomas and 19,568 with seminomas. Eight hundred and twenty four patients (2%) were diagnosed with primary mediastinal GCTs and 1,469 (4%) with nonmediastinal extragonadal tumors. Patients with mediastinal GCTs had an increased risk for death related to hematopoietic malignancies (hazard ratio [HR] = 8.84; 95% confidence interval [CI]: 3.16–24; P<0.0001) and cardiovascular disorders (HR = 4.45; 95% CI: 2.52–8.0; P<0.0001), but no significant difference in risk of dying of solid cancers (HR = 1.46; 95% CI: 0.36–5.9; P = 0.59) compared to patients with gonadal GCTs. Patients with nonmediastinal extragonadal GCTs had a significantly increased risk for dying of cardiovascular disorders (HR = 2.75; 95% CI: 1.67–4.51; P<0.0001), but not a significantly different risk for dying of hematopoietic malignancies (HR = 0.93; 95% CI: 0.13–6.84; P = 0.94) or solid cancers (HR = 1.45; 95% CI: 0.68–5.0; P = 0.23) compared with patients with gonadal GCTs.ConclusionsPatients with GCTs and extragonadal primary sites have an increased risk for death from cardiovascular disease and hematopoietic malignancies compared to those with gonadal GCTs, and could benefit from more intense preventive measures to decrease the risk of death related to these disorders. 相似文献

ObjectiveThe aim of this study was to evaluate comparative outcomes for percutaneous coronary intervention (PCI) versus coronary artery bypass grafting (CABG) in patients with reduced ejection fraction.MethodsAll patients from the University of Pittsburgh Medical Center from 2011 to 2018 who had reduced preoperative ejection fraction (<50%) and underwent CABG or PCI for coronary revascularization were included in this study. Patients were risk-adjusted with propensity matching (1:1) and primary outcomes included long-term survival, readmission, and major adverse cardiac and cerebrovascular events (MACCE).ResultsA total of 2000 patients were included in the current study, consisting of CABG (n = 1553) and PCI (n = 447) cohorts with a mean ejection fraction of 35% ± 9.53%. Propensity matching yielded a 1:1 match with 324 patients in each cohort, controlling for all baseline characteristics. Thirty-day mortality was similar for PCI versus CABG (6.2% vs 4.9%; P = .49). Overall mortality over the study follow-up period (median, 3.23 years; range, 1.83-4.98 years) was significantly higher for the PCI cohort (37.4% vs 21.3%; P < .001). Total hospital readmissions (24.1% vs 12.9%; P = .001), cardiac readmissions (20.4% vs 11.1%; P = .001), myocardial infarction event (7.7% vs 1.8%; P = .001), MACCE (41.4% vs 23.8%; P < .001), and repeat revascularization (6.5% vs 2.6%; P = .02) occurred more frequently in the PCI cohort. Freedom from MACCE at 1 year (74.4% vs 87.0%; P < .001) and 5 years (54.5% vs 74.0%; P < .001) was significantly lower for the PCI cohort. On multivariable cox regression analysis, CABG (hazard ratio, 0.57; 95% confidence interval, 0.44-0.73; P < .001) was significantly associated with improved survival. Prior liver disease, dialysis, diabetes, and peripheral artery disease were the most significant predictors of mortality. The cumulative incidence of hospital readmission was lower for the CABG cohort (hazard ratio, 0.51; 95% confidence interval, 0.37-0.71; P < .001). Multivariable cox regression for MACCE (hazard ratio, 0.48; 95% confidence interval, 0.39-0.58; P < .001) showed significantly fewer events for the CABG cohort.ConclusionsPatients with reduced ejection fraction who underwent CABG had significantly improved survival, lower MACCE, and fewer repeat revascularization procedures compared with patients who underwent PCI. 相似文献

The success of direct-acting antiviral (DAA) therapy has led to near-universal cure for patients chronically infected with hepatitis C virus (HCV) and improved post–liver transplant (LT) outcomes. We investigated the trends and outcomes of retransplantation in HCV and non-HCV patients before and after the introduction of DAA. Adult patients who underwent re-LT were identified in the Organ Procurement and Transplantation Network/United Network for Organ Sharing database. Multiorgan transplants and patients with >2 total LTs were excluded. Two eras were defined: pre-DAA (2009-2012) and post-DAA (2014-2017). A total of 2112 re-LT patients were eligible (HCV: n = 499 pre-DAA and n = 322 post-DAA; non-HCV: n = 547 pre-DAA and n = 744 post-DAA). HCV patients had both improved graft and patient survival after re-LT in the post-DAA era. One-year graft survival was 69.8% pre-DAA and 83.8% post-DAA (P < .001). One-year patient survival was 73.1% pre-DAA and 86.2% post-DAA (P < .001). Graft and patient survival was similar between eras for non-HCV patients. When adjusted, the post-DAA era represented an independent positive predictive factor for graft and patient survival (hazard ratio [HR]: 0.67; P = .005, and HR: 0.65; P = .004) only in HCV patients. The positive post-DAA era effect was observed only in HCV patients with first graft loss due to disease recurrence (HR: 0.31; P = .002, HR 0.32; P = .003, respectively). Among HCV patients, receiving a re-LT in the post-DAA era was associated with improved patient and graft survival. 相似文献

IntroductionDonor nephrectomy (DN) is a procedure performed to provide recipients with a kidney to treat end-stage renal disease. The following analysis evaluated depression diagnosis in DN patients compared to controls.MethodsDN patients and matched controls were identified between 2000 and 2009 from the Statewide Planning and Research Cooperative System database. Cohorts were tracked for depression incidence. Multivariable logistic regression was used to determine independent predictors of a postoperative depression diagnosis.ResultsThe total study cohort included 2108 DN cases and 2108 controls. In both donors and controls, the baseline rate of depression was 0.95% (n = 20). The 5-year incidence of depression diagnosis after exposure increased in both cohorts (donors: 2.5%, n = 53; controls: 7.2%, n = 152; P < .001). The 5-year relative risk for developing depression was 2.65 (CI 1.59-4.42, P = .0002) in donors and 7.60 (CI 4.79-12.07, P < .001) in controls. On multivariable regression, being a donor was associated with reduced risk of developing postoperative depression (OR = 0.322, CI 0.233-0.445, P < .001), and the greatest risk factor for postoperative depression was a prior depressive diagnosis (OR = 7.811, CI 3.814-15.997, P < .001).ConclusionOur analysis shows that the strongest risk factor for depression was a prior diagnosis of depression. However, willingness to undergo donor nephrectomy is associated with less subsequent depression than the control population, suggesting that kidney donors may be a more resilient cohort. 相似文献

BackgroundSimultaneous bilateral total knee arthroplasty (BTKA) is associated with a higher risk but can be perceived to afford faster improvement and mitigated costs versus staged BTKA. We aimed to explore (1) health care utilization, (2) surgical supply costs of simultaneous BTKA; and (3) 1-year improvement in patient-reported pain, function, and quality of life (QOL) versus staged BTKA.MethodsA prospective cohort of 198 simultaneous and 625 staged BTKAs was obtained (2016-2020). Simultaneous BTKA cohort was propensity score-matched (1:2) to a similar group of staged patients (simultaneous = 198 versus staged = 396). Outcomes included length of stay, discharge disposition, 90-day readmission, 1-year reoperation, surgical episode supply cost, Knee Injury and Osteoarthritis Outcome Score (KOOS)-pain, KOOS-Physical Function Short Form, and KOOS-QOL. Rates of attaining minimal clinically important difference and Patient Acceptable Symptomatic State were calculated.ResultsCompared to both staged BTKA surgeries combined, simultaneous BTKA demonstrated shorter median net length of stay (2.00 [2.00, 3.00] days versus 2.00 [2.00, 4.00] days; P < .001) but higher rates of nonhome discharge (n = 56 [28.3%] versus n = 32 [4.04%]; P < .001), 90-day readmission (n = 20 [10.1%] versus n = 48 [6.06%]; P = .047) and similar reoperation rates (P = .44). Simultaneous BTKA afforded slight reduction in net surgical cost compared to that of both staged BTKAs combined ($643; P = .028). There was no significant difference in 1-year improvement and minimal clinically important difference attainment rates with simultaneous versus staged BTKA for KOOS-pain (P = .137 and P = .99), KOOS-QOL (P = .095 and P = .81), or KOOS-Physical Function Short Form (P = .75 and P = .49, respectively) or Patient Acceptable Symptomatic State (P = .12).ConclusionStaged BTKA is associated with similar 1-year pain, function, and QOL at a better safety profile and minimal surgical supply cost increase compared to simultaneous BTKA. 相似文献

BackgroundIt is unclear how epilepsy may affect total joint arthroplasty outcomes. The purpose of this study is to analyze the impact of epilepsy on prosthesis-related complications following primary total hip arthroplasty (THA) and total knee arthroplasty (TKA).MethodsA retrospective cohort study was conducted using a national database. Patients who have epilepsy underwent a primary THA (n = 6,981) and TKA (n = 4,987) and were matched 1:4 (THA, n = 27,924; TKA, n = 19,948). Rates of low-energy falls and prosthesis-related complications within 2 years postoperatively were compared for patients who did and did not have epilepsy with multivariable logistic regression.ResultsAfter primary TKA, patients who have epilepsy exhibited significantly higher rates of aseptic revision (4.3% versus 3.5%, odds ratio [OR] 1.21, P = .017) and revision for prosthetic joint infection (1.8% versus 1.3%, OR 1.29, P = .041). THA patients who have epilepsy exhibited significantly higher rates of prosthetic dislocation (3.2% versus 1.9%, OR 1.54, P < .001), periprosthetic fracture (2.2% versus 0.8%, OR 2.39, P < .001), and aseptic loosening (1.7% versus 1.1%, OR 1.40, P = .002). Rates of low-energy falls within 2 years after TKA (14.1% versus 6.4%, OR 2.19, P < .001) and THA (33.6% versus 7.5%, OR 5.95, P < .001) were also significantly higher for patients who have epilepsy.ConclusionEpilepsy was associated with significantly higher rates of falls (P < .001) and prosthesis-related complications after primary THA (P < .05) and TKA (P < .05). Precautions should be implemented in this population during intraoperative and perioperative decision-making to reduce complication risk.Level of EvidenceLevel III. 相似文献

BackgroundSingle-center studies support benefits of venoarterial extracorporeal membrane oxygenation (VA-ECMO) as a method of intraoperative support. Propensity-matched data from a large cohort, however, are currently lacking. Therefore, our goal was to compare outcomes of intraoperative VA-ECMO and cardiopulmonary bypass (CPB) during bilateral lung transplantation (LTx) with a propensity analysis.MethodsWe performed a retrospective analysis of 795 consecutive primary adult LTx patients (June 1, 2011-December 26, 2020) using no intraoperative support (n = 210), VA-ECMO (n = 150), or CPB (n = 197). Exclusion criteria included LTx on venovenous-ECMO, single/redo LTx, ex vivo lung perfusion, and concomitant solid-organ transplantation or cardiac procedure. Propensity analysis was performed comparing patients who underwent intraoperative CPB or VA-ECMO.ResultsThe propensity CPB group required more blood products at 72 hours (P = .02) and longer intensive care unit length of stay (P < .001) and ventilator dependence days (P < .001). There were no differences in cerebrovascular accident (P = 1), reintubation (P = .4), dialysis (P = .068), in-hospital mortality (P = .33), and 1-year (P = .67) and 3-year (P = .32) survival. The CPB group had a higher incidence of grade 3 primary graft dysfunction at 72 hours (P < .001). Neither support strategy was a predictor of 1- and 3-year mortality in our multivariable model (VA-ECMO, P = .72 and P = .57; CPB, P = .45 and P = .91, respectively).ConclusionsIntraoperative VA-ECMO during lung transplantation was associated with fewer postoperative blood transfusions, shorter length of mechanical ventilation, and lower incidence of a grade 3 primary graft dysfunction at 72 hours. Although there were some differences in the postoperative course between the VA-ECMO and CPB groups, support type was not associated with differences in survival. 相似文献

IntroductionInflammatory breast cancer (IBC) is an uncommon, but aggressive form of breast cancer that accounts for a disproportionally high fraction of breast cancer related mortality. The aim of this study was to explore the peripheral immune response and the prognostic value of blood-based biomarkers, such as the neutrophil-to-lymphocyte ratio (NLR), in a large IBC cohort.Patients & methodsWe retrospectively identified 127 IBC patients and collected lab results from in-hospital medical records. The differential count of leukocytes was determined at the moment of diagnosis, before any therapeutic intervention. A cohort of early stage (n = 108), locally advanced (n = 74) and metastatic breast cancer patients (n = 41) served as a control population.ResultsThe NLR was significantly higher in IBC compared to an early stage breast cancer cohort, but no difference between IBC patients and locally advanced breast cancer patients was noted. In the metastatic setting, there was also no significant difference between IBC and nIBC. However, a high NLR (>4.0) remained a significant predictor of worse outcome in IBC patients (HR: 0.49; 95% CI: 0.24–1.00; P = .05) and a lower platelet-lymphocyte ratio (PLR) (≤210) correlated with a better disease-free survival (DFS) (HR: 0.51; 95% CI: 0.28–0.93; P = .03).ConclusionPatients with a high NLR (>4.0) have a worse overall prognosis in IBC, while the PLR correlated with relapse free survival (RFS). Since NLR and PLR were not specifically associated with IBC disease, they can be seen as markers of more extensive disease. 相似文献

PurposeLymph node involvement is the most important prognostic factor in breast cancer. It is a multifactorial event determined by patient and tumour characteristics. The purpose of this study was to determine clinical and pathological factors predictive for axillary lymph node metastasis (ALNM) in patients with early breast cancer and to build a model to portend lymph node involvement.MethodsWe evaluated 1300 consecutive patients surgically treated in our institution (2007–2009) for cT1-T2 invasive breast cancer. The patient and tumour characteristics evaluated included: age at diagnosis, number of foci, histologic grade, location, tumour size, histologic subtype, lymphovascular invasion (LVI), estrogen-receptor (ER), progesterone-receptor (PR) and Her-2 status. Univariate and multivariate analyses were performed. Factors significantly associated with ALNM by univariate analysis plus histologic subtype were included in the multivariate analysis.ResultsBy univariate analysis, the incidence of ALNM was significantly associated with the presence of LVI (P < 0.0001), larger tumour size (P < 0.0001), higher histologic grade (P < 0.0001), retroareolar or lateral location in the breast (P < 0.0001), multiple foci (P = 0.0002) and in patients who underwent an axillary lymph node dissection. We found no effect of age, ER?PR nor HER-2 status. By multivariate analysis, ALNM was significantly associated with the presence of LVI (P < 0.0001), larger tumour size (P < 0.0001), axillary lymph node dissection (P = 0.0003), retroareolar and lateral tumour location in the breast (P = 0.0019) and the presence of multiple foci (P = 0.0155).ConclusionsLVI and tumour size emerged as the most powerful independent predictors of ALNM, followed by the location of the tumour in the breast and the presence of multiple foci. 相似文献

The 2018 Revised United Network for Organ Sharing Heart Allocation System (HAS) was proposed to reclassify status 1A candidates into groups of decreasing acuity; however, it does not take into account factors such as body mass index (BMI) and blood group which influence waitlist (WL) outcomes. We sought to validate patient prioritization in the new HAS at our center. We retrospectively evaluated patients listed for heart transplantation (n = 214) at Emory University Hospital from 2011 to 2017. Patients were reclassified into the 6-tier HAS. Multistate modeling and competing risk analysis were used to compare outcomes of transplantation and WL death/deterioration between new tiers. Additionally, a stratified sensitivity analysis by BMI and blood group was performed. Compared with tier 4 patients, there was progressively increasing hazard of WL death/deterioration in tier 3 (HR: 2.52, 95% CI: 1.37-4.63, P = .003) and tier 2 (HR: 5.03, 95% CI: 1.99-12.70, P < .001), without a difference in transplantation outcome. When stratified by BMI and blood group, this hierarchical association was not valid in patients with BMI ≥30 kg/m2 and non-O blood groups in our cohort. Therefore, the 2018 HAS accurately prioritizes the sickest patients in our cohort. Factors such as BMI and blood group influence this relationship and iterate that the system can be further refined. 相似文献

BackgroundWith the introduction of investigational human epidermal growth factor receptor 2 (HER2) targeting treatments, thorough understanding of breast cancer with different HER2 expression levels is critical. The aim of this study was to compare clinicopathologic characteristics and survival of patients with metastatic breast cancer according to the level of HER2 expression.MethodsWomen with distant metastatic breast cancer during 2008–2016 were selected from PALGA, the Dutch Pathology Registry, and linked to the PHARMO Database Network. Breast cancer samples were categorised as HER2 immunohistochemistry score 0 (IHC0), HER2-low or HER2+.ResultsAmong women with hormone receptor (HR) positive metastatic breast cancer (n = 989), 373 (38%) cancers were HER2 IHC0, 472 (48%) were HER2-low and 144 (15%) were HER2+. Among HR negative patients (n = 272), the proportion of HER2 IHC0, HER2-low and HER2+ was 110 (40%), 104 (38%) and 58 (21%) respectively.Within the HR + cohort, patients with HER2 IHC0 or HER2-low cancer were significantly older compared to HER2+ patients. This age difference was not seen in the HR-cohort. The localisation of distant metastases differed significantly between HER2 IHC0 or HER2-low versus HER2+ cases. Survival rates did not differ markedly by subtypes.ConclusionSubstantial proportion of patients had a HER2-low breast cancer. No clear differences in survival were found when comparing HER2 and HR status. Getting more granular insights in the level of HER2 expression and addressing HER2-low as a separate category could help to assess the impact of emerging treatment strategies. Therefore, more detailed information on HER2 expression should be routinely reported. 相似文献

ObjectiveMany clinical studies have been carried out to investigate the relationship between periodontitis and rheumatoid arthritis (RA). Owing to limited evidence and inconsistent findings among these studies, it is unclear whether periodontitis would increase the risk for RA. This meta-analysis was performed to evaluate whether periodontitis represents a risk factor for RA.MethodsPubMed, Cochrane Library, Embase, Web of Science, and Wanfang were searched for eligible studies that compared periodontitis patients with controls. A pooled odds ratio (OR) and 95% confidence interval (CI) were calculated to assess the association between periodontitis and RA.ResultsThirteen studies including a total of 706611 periodontitis patients and 349983 control subjects were included. The pooled OR of RA risk between periodontitis and controls was (OR: 1.69; 95% CI: 1.31–2.17; P < 0.0001), indicating that the patients in periodontitis group had a 69% greater risk for RA than people in control group. When stratified by disease type, the pooled results showed periodontitis represents a risk factor for incident RA (OR = 1.70, 95%CI: 0.75–3.85, P < 0.001) and mixed RA (OR = 1.61, 95%CI: 1.26–2.06; P < 0.001). When stratified by disease duration, the pooled results showed periodontitis represents a risk factor for RA disease duration > 5 years (OR = 2.88, 95%CI: 0.66–12.62, P = 0.018), disease duration < 5 years (OR = 2.59, 95%CI: 0.83–8.11, P < 0.001), mixed disease duration (OR = 1.53; 95%CI: 1.05–2.22, P < 0.001).ConclusionOur meta-analysis revealed an increased risk of RA in patients with periodontitis compared to healthy controls. Moreover, when stratified by disease type, there was a higher risk between incident RA and periodontitis. When stratified by disease duration, the patients with periodontitis might be more closely associated with the RA patients with disease duration >5 years. 相似文献
