Introduction
The purpose of this study was to explore whether the practice of postoperative renal cell carcinoma (RCC) surveillance affords a survival benefit by investigating whether detection of RCC recurrences in an asymptomatic versus symptomatic manner influences mortality.Patients and Methods
We identified 737 patients who underwent partial or radical nephrectomy for M0 RCC between 1998 and 2016. Overall survival and disease-specific survival stratified by the type of recurrence detection (asymptomatic vs. symptomatic) was estimated using Kaplan-Meier probabilities both from the time of surgery and from the time of recurrence. Cox proportional hazard regression models were used to evaluate the impact of the type of recurrence detection on mortality.Results
A total of 78 patients (10.6%) experienced recurrence after surgery, of whom 63 (80.8%) were asymptomatic (detected using routine surveillance) and 15 (19.2%) were symptomatic. The median postoperative follow-up was 47.2 months (interquartile range, 26.3-89.4 months). Five- and 10-year overall survival, from time of surgery, among patients with asymptomatic versus symptomatic recurrences was 57% and 39% versus 24% and 8%, respectively (P = .0002). As compared with asymptomatic recurrences, patients with symptomatic recurrences had an increased risk of overall (OD) and disease-specific death (DSD) both when examined from the time of surgery (OD: hazard ratio [HR], 3.16; 95% confidence interval [CI], 1.33-7.49; P = .0091 and DSD: HR, 3.44; 95% CI, 1.38-8.57; P = .0079) and from the time of recurrence (OD: HR, 2.93; 95% CI, 1.24-6.93; P = .0143 and DSD: HR, 3.62; 95% CI, 1.45-9.01; P = .0058).Conclusions
Capturing RCC recurrences in an asymptomatic manner during routine surveillance is associated with improved patient survival. 相似文献2.

Background
The role of positive surgical margins (PSMs) on the recurrence of renal cell carcinoma (RCC) after partial nephrectomy (PN) is debated, and available evidence lacks long-term data. The aim of this study was to evaluate the predictive role of PSMs on progression-free survival (PFS) in a large cohort followed for at least 5 years.Methods
This study was a retrospective analysis of a prospectively compiled single-institution database collecting complete information on more than 2700 patients who had undergone surgery for renal tumor. The data of all the patients submitted to PN for RCC and with least 5 years follow-up were extracted. Surgical specimens were examined at the time of surgery only by 2 expert uro-pathologists. A PSM was defined as the presence of cancer cells at the inked surface of the specimen. The role of PSMs on survival was estimated by Cox regression models adjusted for influent covariates.Results
A total of 459 patients fulfilled the inclusion criteria and were evaluated. PSMs were observed in 27 (5.9%) cases. No differences in preoperative and pathologic data were found comparing patients with and without PSMs. At a median follow-up of 96 months (interquartile range, 74-131 months), a clinically evident relapse of RCC was diagnosed in 36 (7.8%) patients at a median interval of 36 months from PN. Among these, 6 had a PSM for an incidence of relapse of 22.2% in the PSM group, whereas 30 had negative margins, for an incidence of 6.9% (P = .013). The sites of relapse were distant organs in 18 cases, and the kidney underwent PN in 21. The patients with PSMs showed a borderline significantly higher incidence of distant metastasis (11.1% vs. 3.5%; P = .071) and a significantly higher incidence of renal relapses (14.8% vs. 3.9%; P = .029). Multivariable Cox models confirmed that the presence of PSMs was an independent predictor of PFS (odds ratio, 3.127; P = .013).Conclusions
PSMs are an independent predictor of PFS in patients who underwent PN for RCC, owing to a higher incidence of distant and local relapses. Surveillance in presence of PSMs should be intensified and extended for a long time. 相似文献3.

Background
Radical cystectomy (RC) may occasionally be performed in individuals with metastatic urothelial carcinoma of the bladder (mUCB). However, the role of lymph node dissection (LND) for such cases is unknown. Thus, we tested the effect of RC on cancer-specific mortality (CSM) and overall mortality in mUCB patients and the effect of LND and its extent on CSM.Patients and Methods
Within the Surveillance, Epidemiology, and End Results (SEER) database (2004-2013), we identified patients with mUCB who underwent RC with or without LND or non-RC management. Kaplan-Meier analyses and multivariable Cox regression models (CRMs) were used, after propensity score matching. The number of removed nodes best predicting CSM was identified using cubic splines and then was tested in multivariable CRMs.Results
Of 2314 patients, 319 (13.8%) underwent RC. After 2:1 propensity score matching, CSM-free survival was 14 versus 8 months (P < .001), and overall mortality–free survival was 12 versus 7 months (P < .001) for, respectively, RC and non-RC patients. In multivariable CRMs, lower CSM (hazard ratio = 0.48; P < .001) and lower overall mortality (hazard ratio = 0.49; P < .001) rates were recorded in RC patients. LND status did not affect CSM-free survival (13 vs. 10 months; P = .1). Cubic splines-derived cutoff of ≥ 13 number of removed nodes showed better CSM-free survival (20 vs. 11 months; P = .02) and reduced CSM in CRMs (hazard ratio = 0.67; P = .02).Conclusion
Our study validates the survival benefit of RC in mUCB and highlights the importance of more extensive LND. These findings may corroborate the hypothesis of potential cytoreductive effect of surgery in the context of metastatic disease. 相似文献4.

Background
The prognostic value of tumor sidedness in metastatic colorectal cancer (CRC) has been established, but its impact on nonmetastatic disease remains unclear. Our study aimed to explore the prognostic effect of tumor sidedness by subgroup survival analyses, according to histology and tumor grade in stage I-IV CRCs.Methods
A retrospective population-based study was conducted based on Surveillance, Epidemiology and End Results (SEER) data. Population data in the SEER 9 registry (1975-2014) were used to determine survival trends of CRCs, and associated population data in the SEER 18 registry (2000 to 2014) were used to assess the prognostic impact of tumor sidedness on CRCs.Results
The 5-year cause-specific survival for all subgroups of CRCs improved from 1975 to 2014. Of 238,826 patients, 44.2% had right-sided cancer. Patients with right-sided cancer were more likely to be older, to be women, to have disease of mucinous or signet-ring cell histology, to have more poorly differentiated tumors, and to be diagnosed with a more advanced disease stage. Multivariate Cox regression showed stage I-II right-sided cancers had better cause-specific survival than the left-sided cancers (left colon: hazard ratio [HR] = 1.091, 95% confidence interval [CI], 1.052-1.132; rectum: HR = 1.363; 95% CI, 1.304-1.425; P < .001), while stage III and IV right-sided cancers had worse cause-specific survival. In subgroup analyses by histology and tumor grade within stage III CRCs, right-sided poorly differentiated mucinous adenocarcinoma showed significantly better survival (left colon: HR = 1.352; 95% CI, 1.145-1.596; rectum: HR = 1.125; 95% CI, 0.916-1.381; P = .002).Conclusion
The relationship between sidedness and prognosis in CRCs depends on stage and histopathologic characteristics, especially for stage III disease. 相似文献5.

Background
The rate of noninterventional treatment (NIT) in prostate cancer (PCa) active surveillance (AS) candidates is on the rise. However, contemporary data are unavailable. We described community-based NIT rates within 16 Surveillance Epidemiology and End Results (SEER) registries between 2010 and 2014.Patients and Methods
We identified 23,360 PCa patients who fulfilled the University of California San Francisco AS criteria (prostate-specific antigen [PSA] < 10 ng/mL, clinical T stage ≤ T2a, Gleason score ≤ 6, and positive cores < 33%). Annual NIT rates as well as patient distribution according to PSA, age, number of positive cores, and clinical T stage were studied. Multivariable logistic regression analysis tested NIT predictors.Results
Between 2010 and 2014, the NIT rate increased from 30.2% to 57.5% (P = .004). Within 16 SEER registries, NIT rates ranged from 25.9% to 62%. NIT rate increased uniformly within all examined registries. Of patient and tumor characteristics (PSA > 4 ng/mL, cT2a and > 1 positive core) only the proportion of NIT patients aged < 65 years increased over time from 47.3% to 53.2% (P = .03). By multivariable logistic regression analysis predicting NIT rate, older age (odd ratio [OR] = 1.05), more contemporary year of diagnosis (OR = 1.41), and being unmarried (OR = 1.45) and uninsured (OR = 2.41) were independent predictors.Conclusion
The NIT rate has markedly increased across all examined SEER registries. Nonetheless, important differences distinguish those who received high-end NIT from low-end NIT. PCa characteristics of NIT patients remained unchanged over time. However, in addition to geographical differences in NIT rates, patient characteristics such as age, marital status, and insurance status represent potential NIT access barriers. 相似文献6.

Introduction
Despite the risk of morbidity and mortality associated with autologous hematopoietic cell transplantation (ASCT), there are no clear guidelines as to how to screen for these risks. This study sought to determine the utility of pulmonary function tests (PFTs) prior to ASCT on predicting posttransplant clinical outcomes.Patients and Methods
Patients undergoing ASCT between 2010 and 2012 at the Ottawa Hospital (n = 172) were reviewed. PFT results prior to ASCT were retrieved. The primary outcomes were incidence of intensive care unit (ICU) admission, Seattle Criteria for pulmonary toxicities, and transplant-related mortality (TRM).Results
PFTs were performed for 91 (53%) patients prior to ASCT. There were more smokers in the PFT cohort than the non-PFT cohort (41.8% vs. 19.8%, respectively; P < .0001). Pulmonary toxicity as measured by the Seattle Criteria did not correlate with PFT results (normal vs. abnormal, 8.1% and 6.1%, respectively; P = 1.00). There were no differences in incidence of ICU admission by PFT result (normal vs. abnormal, 2.7% vs. 8.2%, respectively; P = .61) and no difference in TRM by PFT result (normal vs. abnormal, 0% vs. 2.0%, respectively; P = 1.00).Conclusion
Despite testing patients deemed higher risk for pulmonary toxicity, abnormal PFTs did not predict for an increased risk of pulmonary toxicity, ICU admission, or TRM at our center. 相似文献7.

Background
Smoking increases the risk of developing renal cell carcinoma (RCC) but the effect of tobacco consumption on survival outcome of patients with metastatic RCC (mRCC) treated with targeted therapies has not been well characterized.Patients and Methods
The primary outcome was overall survival (OS) and secondary outcome was progression-free survival (PFS). Patients with mRCC were categorized as current, former, and nonsmokers at the time of starting targeted therapy. Smoking data from 1980 patients with mRCC treated with targeted therapy were collected through the International mRCC Database Consortium (IMDC) from 12 international cancer centers.Results
Although former and nonsmokers had comparable OS times (23.8 vs. 23.4 months; P = .898), current smokers had significantly shorter OS (16.1 months; P < .001) than nonsmokers. Current but not former smoking status was an independent poor prognosis factor (hazard ratio [HR], 1.3; P = .002) when adjusted for the IMDC risk criteria. Each pack-year increased the risk of death by 1% (HR, 1.01; P = .036). The duration of first-line therapy response was not different and was 7.7 months versus 7.5 months versus 6.4 months in never, former (P = .609), and current smokers (P = .839), respectively.Conclusion
Active smoking is associated with diminished OS in mRCC patients treated with targeted therapy agents. However, patients who quit smoking returned to a similar risk of death from RCC compared with patients who never smoked. Smoking cessation should be a counseling priority among mRCC patients receiving targeted agents and smoking should be considered as a confounding factor in major clinical trials. 相似文献8.

Background
Objections have been raised to performing risk-reducing salpingo-oophorectomy (RRSO) to reduce disease incidence and mortality of women with BRCA mutations. We aimed to examine the relationship between RRSO and breast cancer (BC) risk and mortality with a meta-analysis.Materials and Methods
We conducted a comprehensive literature search using the PubMed and Embase databases for literature published from these databases' creation to September 2017. Hazard ratio (HR) estimates were identified directly from the original articles. Pooled results were calculated on the basis of nonoverlapping studies by fixed-effect meta-analysis.Results
RRSO was associated with a significant reduction in the incidence of BC in women with BRCA1/2 mutations who had no history of BC (HR = 0.58; 95% confidence interval [CI], 0.37 to 0.78). Even in women with a history of BC, RRSO could reduce the risk of recurrence (HR = 0.50; 95% CI, 0.31 to 0.69). We further found that publication year was a critical interaction factor from a corresponding subgroup analyses in BC risk (Pheterogeneity = .024). In addition, we found that RRSO could improve the survival of women with BC (HR = 0.33; 95% CI, 0.28 to 0.38).Conclusion
Summary estimates presented here indicate that RRSO was closely related to the reduced risk of BC caused by BRCA mutations, but publication year was a critical interaction factor and it should be noted that more recent studies have failed to find a significant reduction in BC risk associated with RRSO. 相似文献9.

Background
Few data examined the potential survival benefit of chemotherapy (CHT) in the setting of metastatic upper urinary tract urothelial carcinoma (mUTUC). We hypothesized that a survival benefit might be associated with the use of CHT in nonsurgically treated primary mUTUC and tested this hypothesis within a large population-based cohort.Patients and Methods
Within the Surveillance, Epidemiology, and End Results database (2004-2014), we identified 539 patients with nonsurgically treated primary mUTUC. Inverse probability of treatment weighting (IPTW)-adjusted Kaplan-Meier plots, as well as multivariable Cox regression models relying on IPTW and landmark analyses, were used to test the effect of CHT versus no CHT on overall mortality and cancer-specific mortality.Results
Of 539 patients with metastatic UTUC, 277 (51.4%) underwent CHT. In nonadjusted and IPTW-adjusted Kaplan-Meier plots, CHT was associated with better overall survival (9 vs. 2 months; P < .001 in both analyses). In multivariable Cox regression models, CHT administration independently predicted lower overall mortality before IPTW (hazard ratio [HR], 0.31; 95% confidence interval [CI], 0.25-0.39; P < .001), as well as after IPTW adjustment (HR, 0.31; 95% CI, 0.25-0.38; P < .001). Similar results were recorded in landmark analyses (HR, 0.52; 95% CI, 0.38-0.70; P < .001). Finally, virtually the same results were obtained for cancer-specific mortality.Conclusions
Our analyses suggest a survival benefit after CHT in the setting of nonsurgically treated primary mUTUC. 相似文献10.

Background
The objective of this study was to investigate positive surgical margin (PSM) rates in patients with prostate cancer treated with radical prostatectomy (RP) and assess PSM impact on cancer-specific mortality (CSM).Patients and Methods
Within the Surveillance, Epidemiology, and End Results (SEER) database (2004-2015), we identified men who underwent RP with pathologic T2 or T3a stage. Annual trends of PSM rates were plotted. Subgroups focused on geographic regions, namely the North Central, Northeast, South, and West. Cumulative incidence plots depicted other-cause mortality-adjusted CSM rates. Multivariable competing risks regression models tested the relationship between PSM and CSM. Subgroup analyses focused on pathologic stage, Gleason score, and geographic region.Results
Of 153,329 patients treated with RP, 12.3% (n = 18,935) exhibited PSM. Overall, in pathologic T2 stage and pathologic T3a stage, PSM rates decreased during the study period from 18.7% to 9.7% (P < .001), 15.7% to 7.3% (P < .001), and 39.0% to 18.0% (P < .001), respectively. In subgroup analyses focusing on geographic regions, PSM rates universally decreased. However, the magnitude differed. In multivariable competing risks regression models, PSM rates were associated with higher CSM (hazard ratio, 1.45; P < .001). However, geographic regions failed to reach independent predictor status. Insufficient information about PSM focality, length, and associated Gleason score represent important limitations.Conclusion
It is encouraging that PSM rates decreased during the study period, even after stratification according to tumor stage. PSM decreased within the 4 examined geographic regions. However, the rate of decrease varied in magnitude, but geographic regions did not represent an independent predictor of PSM. 相似文献11.

Background
Cardiovascular events (CVEs) have been observed in patients with chronic myeloid leukemia treated with second-generation tyrosine kinase inhibitors.Patients and Methods
We retrospectively evaluated the incidence of CVEs on 233 consecutive patients with chronic myeloid leukemia, of which 116 were treated with imatinib, 75 with dasatinib, and 42 with nilotinib. The median follow-up was 2047, 1712, and 1773 days, respectively.Results
The cumulative incidence of CVEs was 4.29%. Three events occurred during dasatinib treatment, 6 during nilotinib treatment, and none during imatinib treatment (P ≤ .001). Arterial occlusive events occurred in 2 (2.6%) of 75 patients treated with dasatinib and in 6 (14.2%) of 42 patients treated with nilotinib (P ≤ .001). Furthermore, all of them occurred in patients with high-risk (n = 2) and very high-risk (n = 6) cardiovascular risk, contributing to 4.3% of mortality.Conclusion
CVEs were more frequent in patients treated with second-generation tyrosine kinase inhibitors. Arterial occlusive events were more frequent in patients treated with nilotinib, with high and very high cardiovascular risk. 相似文献12.

Aims
Delaying progression, ameliorating symptoms and maintaining quality of life (QoL) are primary aims of treatment for metastatic castrate-resistant prostate cancer (mCRPC). Real-world rather than clinical trial data about symptoms and side-effects are sparse. In EXTREQOL, patients' QoL, pain and information needs were recorded during treatment.Material and methods
Men with mCRPC from 20 UK cancer centres starting various systemic mCRPC treatments completed QoL, pain and information needs questionnaires at baseline, 3 and 6 months.Results
In total, 132 patients were recruited. Overall QoL declined significantly by 6 months (Functional Assessment of Cancer Therapy-Prostate [FACT-P] mean = –3.89, 95% confidence interval –6.7 to –1.05, P = 0.007; Trial Outcome Index [TOI] analysis mean = –3.10, 95% confidence interval –5.34 to –0.83, P = 0.007). Those who came off novel therapy and remained on luteinising hormone-releasing hormone agonist therapy alone had worse scores than patients receiving concomitant chemotherapy (Prostate Concerns Subscale mean difference = –4.45, 95% confidence interval –7.06 to –1.83, P = 0.001; TOI mean difference = –5.62, 95% confidence interval –10.97 to –0.26, P = 0.040). At 3 and 6 months, men who reported pain at baseline improved (43%, 40%), but for others pain levels remained the same (45%, 42%) or worsened (13%, 18%). Information regarding supportive care was lacking throughout the period of time on the study.Conclusion
Most mCRPC treated patients experience reduced QoL and inadequate pain control. More help with pain management and better information provision regarding supportive care is warranted. 相似文献13.

Background
Anal squamous cell carcinoma (ASCC) is a rare, human papilloma virus-associated cancer. The purpose was to investigate the population-based incidence rates, age and gender distribution, and survival of ASCC.Materials and Methods
All primary ASCC in 1987 to 2016 were identified in the Cancer Registry of Norway (N = 1548), with information on age, gender, stage, county of residence, radiotherapy, and survival.Results
Median age was 66 years; 71% were females. World age-standardized incidence rates increased (1987-2016) from 0.79 (95% confidence interval [CI], 0.69-0.90) to 1.10 (95% CI, 1.00-1.22) per 100,000 person-years in females and, from 0.34 (95% CI, 0.28-0.42) to 0.47 (95% CI, 0.40-0.54) in males. Estimated annual percentage change was 1.7 (95% CI, 0.9-2.6) for females and 1.3 (95% CI, ?0.1 to 2.7) for males. Incidence rates increased with age; the relative risk was higher in major cities. Five-year net survival increased from 63.4% to 72.7% (1987-2016), but for age ≥ 70 years remained ～57%. Net survival was dependant on stage, age, and gender. Five-year net survival (1997-2016) was 76.4% after curative radiotherapy, and 18.0% after palliative radiotherapy.Conclusion
ASCC incidence rates increased from 1987 to 2016, and survival improved for patients < 70 years. Five-year net survival was 76% after curative radiotherapy in Norway. 相似文献14.

Purpose
To assess the prognostic value of PI3K-AKT-mTOR signaling pathway up-regulation in a contemporary cohort of penile squamous-cell carcinoma (PSCC) patients.Patients and Methods
Tissue microarrays were constructed for 57 patients with invasive PSCC treated at our institution between 2000 and 2013. Immunohistochemical staining was performed for PTEN, AKT, and S6. Human papillomavirus (HPV) in-situ hybridization for high-risk subtypes was also performed. Biomarker expression was evaluated by a semiquantitative H score. Overall survival, disease-specific survival and recurrence-free survival stratified by biomarker expression (low vs. high) were estimated by the Kaplan-Meier method. Multivariable Cox regression models were used to determine predictors of mortality and recurrence.Results
HPV in-situ hybridization was positive in 23 patients (40%). PTEN was down-regulated in 43 patients (75%), while phosphorylated-AKT (p-AKT) and phosphorylated-S6 (p-S6) were up-regulated in 27 (47%) and 12 patients (21%), respectively. In multivariable Cox regression models, patients with low expression of p-AKT had an increased risk of recurrence (hazard ratio [HR] = 3.95; 95% confidence interval [CI], 1.47-10.59; P = .02), while those with low expression of p-S6 had an increased risk of overall mortality (HR = 6.15; 95% CI, 1.55-24.36; P = .01). HPV status was an independent predictor of overall survival (HR = 6.99; 95% CI, 2.42-20.16; P < .001) and disease-specific survival (HR = 6.74; 95% CI, 2.02-22.48; P = .002).Conclusion
PI3K-AKT-mTOR signaling pathway up-regulation and HPV coinfection in PSCC are associated with favorable disease. mTOR pathway biomarkers along with HPV status may represent novel prognosticators for risk stratification of PSCC patients and may help guide treatment decisions and follow-up strategies. These findings require further investigation. 相似文献15.

Background
The role of histology subtype on the prognosis of T1-2 breast cancer patients receiving breast-conserving surgery (BCS) is not clear.Methods
The Surveillance, Epidemiology, and End Results (SEER) Program was used to compare overall survival, second primary cancer-free survival (CFS), and local recurrence risk (LR) for patients with invasive lobular carcinoma (ILC) and invasive ductal carcinoma (IDC), both receiving BCS.Results
The study enrolled 196,688 patients with T1-2 disease receiving BCS, including 12,906 with ILC and 183,782 with IDC. Patients with IDC showed higher unadjusted annual rates of BCS than ILC. Five- and 10-year estimated survival rates were, respectively, 92.06% and 86.14% in ILC, compared to 90.50% and 85.26% in IDC (P = .12). In multivariable Cox regression, ILC patients showed advantage over IDC in overall survival (hazard ratio [HR] = 0.93, P = .001), whereas no significant differences in CFS (HR = 1.03, P = .33) and LR (HR = 1.17, P = .06) were found, which were consistent with results from matched cohort. In subgroup analyses, patients with grade III ILC had poorer CFS (HR = 1.23, P = .009) and higher LR (HR = 1.59, P = .01) than IDC.Conclusion
Histologic type is of prognostic importance in T1-2 patients receiving BCS, and surgeons should be cautious in performing BCS for individuals with grade III ILC. 相似文献16.

Background
The aim of this study is to investigate trends in the incidence and survival of patients with gastric neuroendocrine neoplasms (g-NENs).Methods
and methods: Patients diagnosed with g-NENs (n = 3523) were identified from the Surveillance, Epidemiology and End Results (SEER) database. Patients diagnosed with g-NENs (n = 199) in our department were designated as a validation dataset. Nomograms were adopted to predict disease-specific survival (DSS) and overall survival (OS).Results
The incidence of g-NENs is steadily increasing over time at a rate higher than any other cancer [annual percentage change (APC) = 6.3%, 95% confidence interval (CI) 5.6–7.0]. The 1-, 3-, and 5-year DSS rates were 87%, 78.6% and 70.6%, respectively, and the corresponding OS rates were 84.3%, 71.9%, and 53.7%, respectively. The multivariate analysis identified age, sex, T stage, M stage, and histological type as independent prognostic factors for both DSS and OS (all P < .05). The concordance indexes of the nomograms for DSS and OS in the training dataset were superior to those of the traditional tumor-node-metastasis (TNM) staging system [0.899 and 0.849 versus 0.864 and 0.783]. Calibration plots of the nomograms showed that the probability of DSS and OS closely corresponded to the actual observations in both the SEER-based training dataset and our inpatient validation dataset.Conclusion
The incidence of g-NENs has been steadily increasing at a rapid rate over the past four decades. The nomograms based on the analysis of the SEER database were superior to the TNM staging system in predicting the clinical outcomes for g-NEN patients. 相似文献17.

Purpose
To perform a retrospective analysis of the prognostic relevance of clinicopathologic parameters in a well-documented cohort of patients treated with all-trans-retinoic acid (ATRA)-based induction regimens in order to discover which indicators can predict a high risk of early death (ED) and patient survival.Patients and Methods
We analyzed data of 288 newly diagnosed adult acute promyelocytic leukemia patients in Hangzhou, China. The median follow-up time was 32 months (range, 6-78 months).Results
The 3-year disease-free and overall survival rates were 90.83% and 91.69%, respectively. In the multivariable analysis, older age (≥ 60 years) was the only independent risk factor for ED (hazard ratio [HR] = 15.057; P = .004). High white blood cell count was not a risk factor for ED (P = .055), but it was for relapse (HR = 2.7; P = .009). FLT3 mutation (HR = 3.9; 95% confidence interval, 1.4 to 10; P = .007) and older age (≥ 60 years) (HR = 5.3; 95% confidence interval, 2.4 to 11; P < .001) were prognostic factors for poorer disease-free and overall survival. Interestingly, CD15 negativity (HR = 0.23; P = .049) was a prognostic factor for relapse. The ED rate was 5.9% (17/288 patients).Conclusion
The perceived impact of the identification of these high-risk factors should be described in order to decide whether any modifications to treatment strategy should be entertained. 相似文献18.

Introduction
Minimally invasive approaches are increasingly being used for the conduct of complex surgical procedures. Whether the benefits of minimally invasive approaches compared to thoracotomy for sublobar and lobar lung resection for NSCLC are realized for patients undergoing pneumonectomy is not clear.Methods
The National Cancer Database was queried for patients who underwent pneumonectomy for NSCLC from 2010 to 2014. Case data from patients who underwent resection by minimally invasive surgery (MIS) were compared with those from patients who received thoracotomy (open) in an intention-to-treat analysis. Associations between potential covariates and treatment were analyzed using the Pearson chi-square test for categorical variables and Wilcoxon rank sum test for continuous variables. Univariable and multivariable logistic models and proportional hazards model were used to assess the effect of surgical approach on 30-day and 90-day mortality and overall survival. Relative prognosis was summarized using odds ratios and hazards ratios estimates and 95% confidence limits.Results
A total of 4,938 patients underwent pneumonectomy during the study period, of which 755 (15.3%) were completed by MIS. No difference was noted in 30- and 90-day mortality rates for MIS compared to open approaches (6.8% and 12.3% versus 6.7% and 11.9%, respectively; p = 0.9 and 0.86, respectively). Tumor histology and stage characteristics were similar between the two groups. The mean number of lymph nodes examined was higher in the MIS group compared to the open thoracotomy group (17.1 ± 0.4 versus 16.1 ± 0.2, p = 0.034). The conversion rate for the MIS cohort was 36.7%. Surgical approach was not associated with any difference in perioperative mortality with univariable or multivariable analysis. MIS was associated with improved overall survival on univariable analysis, but this was not evident with multivariable analysis.Conclusions
Pneumonectomy performed by minimally invasive approaches does not compromise perioperative mortality or long-term outcomes. Further investigation into the impact of minimally invasive approaches on perioperative outcomes for whole-lung resection is warranted. 相似文献19.

Background
Controversy exists regarding the appropriateness of immediate breast reconstruction (IBR) in patients with metastatic breast cancer (MBC).Patients and Methods
By using the Surveillance, Epidemiology, and End Results (SEER) database, data of patients with de novo MBC undergoing mastectomy with or without IBR were assessed. The trend of IBR in de novo MBC was explored. Comparisons of the distribution of clinicopathologic characteristics were evaluated by chi-square and Fisher exact tests. The predictors of IBR in de novo MBC were evaluated by multivariate logistic regression. The survival outcomes were compared by Cox hazards models adjusting for known clinicopathologic variables in both the entire population and in the matched cohorts.Results
Between 1998 and 2015, 5.2% of patients with de novo MBC undergoing mastectomy received IBR. The rate of IBR increased significantly, from 6.3% in 1998 to 16.8% in 2015. Patients undergoing IBR were younger and had smaller tumor size, fewer positive lymph nodes, lower proportion of hormone receptor–negative disease and lung metastasis, and better economic status. They were also more likely to receive radiotherapy and chemotherapy. Although IBR was an independent favorable prognostic factor for breast cancer–specific survival and overall survival in the whole population, there were no statistically significant differences between IBR and mastectomy for breast cancer–specific survival (P = .892) and overall survival (P = .708) in the well-matched analysis.Conclusion
IBR in selected de novo MBC could be an acceptable practice when balancing quality of life, underlying health care burden, and oncologic risks. 相似文献20.
