Background
Fluorouracil-based preoperative chemoradiotherapy has become the standard treatment for stage II/III rectal cancer. In order to improve the overall survival (OS) and disease-free survival (DFS), we added oxaliplatin to the standard treatment, and compared the effectiveness of these two treatment patterns.Methods
A total of 206 patients enrolled in the prospective study had histologically confirmed rectal cancer of clinical stage II/III during July 2007 to July 2010. They were randomized into the experimental group received oxaliplatin and capecitabine in combination with radiotherapy, and the control group received capecitabine in combination with radiotherapy. All patients received surgery in 6−10 weeks after chemoradiotherapy and adjuvant chemotherapy with mFOLFOX6. The primary endpoints were DFS and OS, and the secondary endpoints included toxicity, compliance, and histopathological response.Results
The 3-year OS in the experimental group and the control group was 90.29% vs. 86.41% (P>0.05), and the 3-year DFS was 80.58% vs. 69.90% (P>0.05). The pathological complete remission (pCR) rates were 23.30% and 19.42%, respectively (P=0.497). The 3-year local recurrence rates were 4.85% vs. 5.83% (P=0.694), and the 3-year distant metastasis rates were 16.50% and 28.16%, respectively (P=0.045). There were no significant differences in most grade 3−4 toxicities between two groups, however, grade 3−4 diarrhea occurred in 16.50% (17/103) of the experimental group, compared with 6.80% (7/103) of the control group (P=0.030). Also, the total grade 3−4 acute toxicity showed a significant difference (10.68% vs. 21.36%, P=0.037).Conclusions
The experimental treatment did not lead significantly improved OS and DFS, and thus longer follow-up is warranted for our patient cohort. Adding oxaliplatin to capecitabine-based preoperative chemoradiotherapy can significantly reduce metastasis, but has only minimal impact on local recurrence. Although grade 3−4 toxicity rate increased (primarily gastrointestinal toxicity), patients can stand to be followed up with allopathic treatment. 相似文献2.

Purpose
This pilot study aimed to evaluate prognostic factors of postmastectomy radiotherapy (PMRT) for breast cancer patients undergoing systemic therapy in either preoperative or postoperative setting.Methods
Between 2003 and 2009, 113 patients received PMRT: 61 underwent preoperative systemic therapy (PST subgroup) and 52 received postoperative systemic therapy (non-PST subgroup).Results
The median follow-up time was 72.3 months (range, 34.0-109.4 months) for surviving patients. In univariate analysis of all patients, disease-free survival (DFS) was associated with age, nodal ratio (NR), and Ki-67 expression; overall survival (OS) was associated with NR and Ki-67 expression. Pathologic N stage and HER2 expression were marginally associated with DFS and OS. In the non-PST subgroup, DFS was associated with age, NR, venous invasion, and Ki-67 expression; OS was associated with age. In the PST subgroup, DFS was associated with ypN stage and NR; OS was associated with ypN, histologic grade, HER2 expression, and p53 expression. In multivariate analysis of all patients, DFS and OS were significantly associated with NR (p=0.003 and p=0.019, respectively) and Ki-67 expression (p=0.002 and p=0.015, respectively). Patients were classified into low-risk (NR ≤0.2 and Ki-67 ≤20%; n=34), intermediate-risk (NR >0.2 or Ki-67 >20%; n=63), and high-risk (NR >0.2 and Ki-67 >20%; n=16) subgroups. All low-risk patients were alive at the time of analysis. High-risk (p<0.001 and p=0.001, respectively) and intermediate-risk (p=0.022 and p=0.008, respectively) patients had significantly shorter DFS and OS than low-risk patients. This prognostic model was statistically significant for DFS when applied to the PST (p=0.001) and non-PST (p=0.016) subgroups separately.Conclusion
For breast cancer patients undergoing PMRT, NR and Ki-67 are potential prognostic factors. A model using these factors might help predict a poor prognosis. Whether NR and Ki-67 are also prognostic for different setting of systemic therapy, preoperative or postoperative, warrants further study. 相似文献3.
Background:
Haemoptysis is a common symptom of lung cancer. Its prognostic role and mechanisms are still poorly understood.Methods:
We retrospectively reviewed 666 consecutive patients with primary lung adenocarcinoma who underwent complete resection. The prognostic value of haemoptysis with respect to overall survival (OS), disease-specific survival (DSS) and disease-free survival (DFS) was analysed. To further explore the possible mechanisms of haemoptysis, we evaluated vascular endothelial growth factor (VEGF) expression, tumour necrosis, vascular invasion and extratumoural microvessel density (MVD) in 112 randomly selected patients.Results:
Haemoptysis predicted poor OS, DSS and DFS in operable lung adenocarcinoma (all P<0.001). In addition, haemoptysis was associated with high white blood cell (WBC) count (P=0.032), high fibrinogen (Fib; P<0.001), high tumour greatest dimension (P<0.001), severe vascular invasion (P=0.002) and central tumour location (P<0.001). We obtained no statistically significant differences of VEGF expression, tumour necrosis and extratumoural MVD in haemoptysis and non-haemoptysis groups.Conclusion:
Our study demonstrates that haemoptysis predicts poor OS, DSS and DFS in lung adenocarcinoma after curative resection. Vascular invasion rather than angiogenesis or tumour necrosis could be the most important mechanism of haemoptysis in lung adenocarcinoma. 相似文献4.

Objective
To verify whether it can be justified to classify patients to stage IIIC epithelial ovarian cancer based on nodal involvement only.Methods
This study included all consecutive patients with stage IIIC epithelial ovarian cancer who underwent upfront cytoreductive surgery according to the FIGO guideline followed by platinum based chemotherapy from September 1989 to September 2006 at Asan Medical Center.Results
During the study period, a total of 272 patients met the inclusion criteria. Optimal cytoreduction was achieved in 213 patients, and complete cytoreduction was achieved in 85 patients. Median follow-up time was 37 months (range, 6-181 months). The 5-year disease free survival (DFS) and overall survival (OS) rate of all patients were 23% and 57%, respectively. Forty-one patients were allocated to stage IIIC by positive nodes only. Patients with stage IIIC disease due to positive nodes only had significantly longer DFS and OS compared to other stage IIIC patients (p<0.001 and p<0.001). The DFS and OS of these patients was significantly better than those of other stage IIIC patients who achieved complete or optimal cytoreduction (p<0.001 and p<0.001). The outcome was even better than that of stage IIIA and IIIB patients (p<0.05 and p<0.05).Conclusion
Patients with stage IIIC epithelial ovarian cancer due to positive nodes only had a more favorable prognosis compared to other stage IIIC patients. Therefore, reevaluation of the current FIGO staging system for stage IIIC epithelial ovarian cancer is required. 相似文献6.

Background:
Previous investigations in pancreatic cancer suggest a prognostic role for α-smooth muscle actin (α-SMA) expression and stromal density in the peritumoural stroma. The aim of this study was to further validate the impact of α-SMA expression and stromal density in resectable pancreatic cancer patients treated with adjuvant gemcitabine compared with untreated patients.Methods:
CONKO-001 was a prospective randomised phase III study investigating the role of adjuvant gemcitabine as compared with observation. Tissue samples of 162 patients were available for immunohistochemistry on tissue microarrays to evaluate the impact of α-SMA expression and stromal density impact on patient outcome.Results:
High α-SMA expression in tumour stroma was associated with worse patient outcome (DFS: P=0.05, OS: P=0.047). A dense stroma reaction was associated with improved disease-free survival (DFS) and overall survival (OS) in the overall study population (DFS: P=0.001, OS: P=0.001). This positive prognostic impact was restricted to patients with no adjuvant treatment (DFS: P<0.001, OS: P<0.001). In multivariable analysis, α-SMA and stromal density expression were independently predictive factors for survival.Conclusions:
Our data confirm the negative prognostic impact of high α-SMA expression in pancreatic cancer patients after curatively intended resection. In contrast to former investigations, we found a positive prognostic impact for a dense stroma. This significant influence was restricted to patients who received no adjuvant therapy. 相似文献7.

Background
An anastomotic leak (AL) after colorectal surgery is one major reason for postoperative morbidity and mortality. There is growing evidence that AL affects short and long term outcome. This prospective German multicentre study aims to identify risk factors for AL and quantify effects on short and long term course after rectal cancer surgery.Methods
From 1 January 2000 to 31 December 2010 381 hospitals attributed patients to the prospective multicentre study Quality Assurance in Colorectal Cancer managed by the Otto-von-Guericke-University Magdeburg (Germany). Included were 17 867 patients with histopathologically confirmed rectal carcinoma and primary anastomosis. Risk factor analysis included 13 items of demographic patient data, surgical course, hospital volume und tumour stage.Results
In 2 134 (11.9%) patients an AL was diagnosed. Overall hospital mortality was 2.1% (with AL 7.5%, without AL 1.4%; p < 0.0001). In multivariate analysis male gender, ASA-classification ≥III, smoking history, alcohol history, intraoperative blood transfusion, no protective ileostomy, UICC-stage and height of tumour were independent risk factors. Overall survival (OS) was significantly shorter for patients with AL (UICC I-III; UICC I, II or III - each p < 0.0001). Disease free survival (DFS) was significantly shorter for patients with AL in UICC I-III; UICC II or UICC III (each p < 0.001). Rate of local relapse was not significantly affected by occurrence of AL.Conclusion
In this study patients with AL had a significantly worse OS. This was mainly due to an increased in hospital mortality. DFS was also negatively affected by AL whereas local relapse was not. This emphasizes the importance of successful treatment of AL related problems during the initial hospital stay. 相似文献8.

Background
Evidence from dated and moderate quality trials supports a modest survival benefit for intensive surveillance in resected colon cancer (CC). This study evaluates surveillance in a modern population-based cohort of stage III CC patients (pts).Methods
Records of pts who initiated oxaliplatin-based adjuvant chemotherapy (AC) for stage III CC between 2006-2011 at the British Columbia Cancer Agency (BCCA) were reviewed. Kaplan-Meier and log rank test were generated to investigate whether diagnosis of recurrence based on symptoms was associated with worse overall survival (OS). OS1 and OS2 were measured from date of recurrence or date of initial surgery, respectively.Results
Of 635 pts who received AC for stage III CC, 175 pts (27.5%) recurred and 118 (18.6%) died at a median follow-up of 67.7 months. Recurrences were detected by surveillance in 149 pts (41% by CEA elevation and 44% by abnormal imaging), and symptoms in 26 pts (15%). Patients with surveillance-detected recurrences had a shorter median relapse-free survival (RFS) (18.5 vs. 25.3 months, HR 1.82, P<0.001), and longer median OS1 (28.5 vs. 6.5 months, HR 0.37, P<0.001). However, median OS2 was not significantly different (50.9 vs. 39.1 months, HR 0.66, P=0.091). Pts with surveillance-detected recurrence received more potentially curative metastasectomy (39% vs. 7%, P=0.002) and chemotherapy (70% vs. 50%, P=0.03).Conclusions
In this modern population-based cohort study, the OS impact of detecting asymptomatic recurrences in stage III CC is unclear. However, pts with asymptomatic recurrences were more likely to receive potentially curative metastasectomy and chemotherapy. 相似文献9.

Purpose
Medullary breast carcinomas (MBC) have been known to represent a rare breast cancer subtype associated with a more favorable prognosis than invasive ductal carcinomas (IDC). The purpose of this study was to compare the clinicopathologic characteristics and outcomes of MBC with those of IDC.Methods
We retrospectively reviewed medical records of patients with invasive breast cancer who were managed surgically from August 1995 to June 2010.Results
Fifty-two patients were identified with MBC and 5,716 patients were identified with IDC. The clinicopathologic features, disease-free survival (DFS), and overall survival (OS) of patients with MBC were compared with those of patients with IDC. The MBC group presented at a younger age (p=0.005) and had a significant association with a higher histological grade (p=0.003) and nuclear grade (p<0.001) as well as negative estrogen receptor (p<0.001) and progesterone receptor (p<0.001) status. Lymphatic invasion was absent (p<0.001) and lymph node metastasis was rare (p<0.001). The DFS and OS did not differ significantly between the two groups (5-year DFS: 88.0% vs. 89.2%, p=0.920; 5-year OS: 93.4% vs. 94.4%, p=0.503). In multivariate analysis, the factors associated with DFS and OS were nuclear grade, histological grade, tumor size, lymph node metastasis, estrogen receptor status, progesterone receptor status, and human epidermal growth factor receptor 2 status, chemotherapy, and hormone therapy. However, DFS and OS were not significantly different between IDC and MBC according to histological type itself (DFS: hazard ratio 0.85, 95% confidence interval 0.12-6.05, p=0.866; OS: hazard ratio 1.49, 95% confidence interval 0.21-10.77, p=0.692).Conclusion
Although MBC has specific clinicopathologic features, its prognosis does not differ from IDC and is determined by prognostic factors such as tumor size and lymph node metastasis. Therefore, patients with MBC also require the same intensive treatment provided for IDC. 相似文献10.

Purpose
Cancer tissue may display a wide spectrum of expression phenotypes of epithelial-mesenchymal transition (EMT)-related proteins. The purpose of this study was to investigate the clinical significance of EMT phenotypes in breast cancer.Methods
We evaluated the expression pattern of the EMT-related proteins E-cadherin and fibronectin in samples from 1,495 patients with invasive breast carcinoma (IBC) on tissue microarrays using immunohistochemistry to investigate the clinical significance of EMT phenotypes in IBC. EMT phenotypes were divided into complete type (E-cadherin-negative/fibronectin-positive), incomplete type (hybrid type, E-cadherinpositive/fibronectin-positive; null type, E-cadherin-negative/fibronectin-negative), and wild-type (E-cadherin-positive/fibronectin-negative). We analyzed the correlation of EMT phenotype with clinicopathological factors and patient survival.Results
Loss of E-cadherin was observed in 302 patients (20.2%), and fibronectin was expressed in the cancer cells of 354 patients (23.7%). In total, 64 (4.3%), 290 (19.4%), 238 (15.9%), and 903 (60.4%) samples were categorized as complete, hybrid, null, and wild-type, respectively. The complete EMT phenotype exhibited significant associations with young age (p=0.017), advanced pT (p<0.001) and pN (p<0.001) stages, higher histological grade (p<0.001), lymphovascular invasion (p<0.001), and triple negativity (p<0.001). Patients with complete and hybrid EMT phenotypes had poorer overall survival (OS) and disease-free survival (DFS) than those with the wild-type phenotype (OS, p=0.001; DFS, p<0.001). In multivariate analysis, the hybrid EMT phenotype was an independent prognostic factor for DFS in patients with IBC (p=0.032).Conclusion
EMT phenotypes exhibited significant associations with clinicopathological factors indicating aggressive biologic behavior and poor outcome in patients with IBC. 相似文献11.

Purpose
The aim of this retrospective study was to identify the reliable long term prognostic factors in patients with stage II/III breast cancer who were treated with an adjuvant extension of neoadjuvant chemotherapy (NC).Methods
Women under the age of 70-years, with previously untreated clinical stage II and III breast cancer, were treated with NC, which was comprised of three cycles of FEC (5-FU, epirubicin, and cyclophosphamide every 3 weeks) or MMM (methotrexate, mitoxantrone, and mitomycin-C every 3 weeks) with an adjuvant extension of three cycles of the same regimen.Results
Cumulative 10-years disease-free survival (DFS) was 87.3% for patients with a good response and 55.5% for patients with no response (p=0.032); 92.9% for node negative patients, 75.0% for 1-3 positive nodes, 50.0% for 4-9 positive nodes and no survival for 10 or more positive nodes (p<0.001). Cumulative 10-years overall survival (OS) was 89.1% for patients with good response and 55.5% for patients with no response (p=0.024); 95.2% for node negative patients, 80.0% for 1-3 positive nodes, 50.0% for 4-9 positive nodes and no survival for 10 or more positive nodes (p<0.001). No significant difference was observed in DFS and OS between the FEC and MMM treated groups.Conclusion
Based on a review of data with a long follow-up, only the clinical response to NC and the absolute number of metastatic axillary lymph node identified at surgical staging were independent predictors of both DFS and OS in patients with stage II/III breast cancer patients treated with adjuvant extension of NC. 相似文献12.

Objectives:
To compare the clinical outcome of patients with stage I epithelial ovarian cancer (EOC) who received with fertility-sparing surgery (FSS) with those who underwent radical surgery (RS).Methods:
After a central pathological review and search of the medical records from multiple institutions, a total of 572 patients were retrospectively evaluated. All patients were divided into three groups: group A {FSS (n=74); age, ⩽40} groups B and C [RS; age, 40⩾{(B), n=52} 40<{(C), n=446}].Results:
Five-year overall survival (OS) and disease-free survival (DFS) rates of patients in the groups were as follows: group A, 90.8% (OS)/87.9% (DFS); group B, 88.3% (OS)/84.4% (DFS); group C, 90.6% (OS)/85.3% (DFS), respectively (OS, P=0.802; DFS, P=0.765). Additionally, there was no significant difference in OS and DFS among the three groups stratified to stage IA or IC (OS (IA), P=0.387; DFS (IA), P=0.314; OS (IC), P=0.993; DFS (IC), P=0.990, respectively). Furthermore, patients with a grade 1–2 or 3 tumours in the FSS group did not have a poorer prognosis than those in the RS group.Conclusions:
Stage I EOC patients treated with FSS showed an acceptable prognosis compared with those who underwent RS. 相似文献13.

Background:
The optimum multimodal treatment for oesophageal cancer, and the prognostic significance of histopathological tumour involvement of the circumferential resection margin (CRM+) are uncertain. The aims of this study were to determine the prognostic significance of CRM+ after oesophagectomy and to identify endosonographic (endoluminal ultrasonography (EUS)) features that predict a threatened CRM+.Methods:
Two hundred and sixty-nine consecutive patients underwent potentially curative oesophagectomy (103 surgery alone, 124 neoadjuvant chemotherapy (CS) and 42 chemoradiotherapy (CRTS)). Primary outcome measures were disease-free survival (DFS) and overall survival (OS).Results:
CRM+ was reported in 98 (38.0%) of all, and in 90 (62.5%) of pT3 patients. Multivariate analysis of pathological factors revealed: lymphovascular invasion (HR 2.087, 95% CI 1.396–3.122, P<0.0001), CRM+ (HR 1.762, 95% CI 1.201–2.586, P=0.004) and lymph node metastasis count (HR 1.563, 95% CI 1.018–2.400, P=0.041) to be independently and significantly associated with DFS. Lymphovascular invasion (HR 2.160, 95% CI 1.432–3.259, P<0.001) and CRM+ (HR 1.514, 95% CI 1.000–2.292, P=0.050) were also independently and significantly associated with OS. Multivariate analysis revealed EUS T stage (T3 or T4, OR 24.313, 95% CI 7.438–79.476, P<0.0001) and use or not of CRTS (OR 0.116, 95% CI 0.035–0.382, P<0.0001) were independently and significantly associated with CRM+.Conclusion:
A positive CRM was a better predictor of DFS and OS than standard pTNM stage. 相似文献14.

Background:
Surgical–pathological risk factors were evaluated by weighting the magnitude of significance of multiple risk factors correlating to survival and treatment response in cervical cancer.Methods:
Multivariate analysis was performed for survival outcomes entering seven pathological factors obtained from 540 radical hysterectomy specimens in stage IA2-IIB cervical cancer cases. Hazard ratio (HR) in each risk factor was determined, and the sum of HR scores for the corresponding risk factors was determined per case. Survival curves and postoperative treatment response (concurrent chemoradiotherapy (CCRT) vs radiotherapy alone) were evaluated based on the extent of HR-weighted scores.Results:
Hazard ratios for risk factors relating to disease-free survival (DFS) was: lympho-vascular space invasion 3.95, nodal metastasis 3.88, adenocarcinoma 3.40, large tumour 2.36, positive margin 1.99, deep stromal invasion 1.29, and parametria invasion 1.21. The HR-weighted scoring method showed a high predictive value for recurrence (area-under-curve 0.836, P<0.001). Hazard ratio-weighted scores were negatively correlated to DFS, and the cases with score ⩾12.5 showed 5-year DFS rate of 23.8%. Tumours with larger score offset the benefits of CCRT over radiotherapy alone for postoperative adjuvant treatment (P<0.001).Conclusion:
Surgical–pathological risk factors provide valuable information for survival and management of early-stage cervical cancer when number and significance of risks are weighted. 相似文献15.

Background
Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have shown variability in survival outcomes when used to treat peritoneal surface disease (PSD) from appendiceal and colorectal cancers. The primary goal of this study was to examine outcomes for high-grade appendiceal (HGA) and high-grade colonic primaries after CRS-HIPEC to determine if a significant difference exists between the two groups.Methods
A retrospective analysis of patients with peritoneal dissemination from appendiceal and colonic primaries were identified in a prospectively maintained database of 1,223 CRS-HIPEC procedures performed between 1991 and 2015. Patient demographics, performance status resection status, tumor grade, nodal status, morbidity, mortality, and survival were reviewed with biopsy-proven PSD being classified according to primary site. Univariate and multivariate analyses were performed, and outcomes compared.Results
The study identified 171 CRS-HIPEC procedures for 165 patients: 110 (66.7%) for HGA and 55 (33.3%) for high-grade colonic lesions. Observed median disease-free survival (DFS) and overall survival (OS) for both groups were the same at14.4 and 18 months, respectively. Median survival according to resection status for R0/R1, R2a, and R2b/c were 36, 15.6, and 8.4 months (P<0.0001). Median OS for those who received preoperative chemotherapy versus those who did not were 14.4 and 20.4 months, respectively (P=0.01). For those who received preoperative chemotherapy, no difference was apparent in the DFS interval (P=0.34). Multivariate predictors of OS included resection status (P<0.0001) and lymph node involvement (P=0.0005).Conclusions
Preoperative chemotherapy offered no clear DFS or OS benefit, for HGA or high-grade colon cancer patients. Complete cytoreduction offered the greatest survival benefit to both groups with a correlating drop in survival to resection status. Outcomes for high grade appendiceal cancer are remarkably similar to colon cancer. 相似文献16.

Background
The purpose of the study was to evaluate the correlation between the maximum standardized uptake value (SUVmax), size of primary lung lesion, disease-free survival (DFS) and overall survival (OS) in patients with stage I and II non-small cell lung cancer (NSCLC) in 2 years follow-up.Patients and methods.
Forty-nine patients with stage I–II NSCLC were included in this study. Pre-surgical 2-deoxy-2-[18F]fluoro-D-glucose positron-emission tomography (18F-FDG PET/CT) study was performed for all patients. The relationship between SUVmax, tumour size and clinical outcome was measured. The cut-off value for SUVmax and tumour size with the best prognostic significance, probability of DFS and the correlation between SUVmax and the response to therapy were calculated.Results
There was a statistically significant correlation between SUVmax and DFS (p = 0.029). The optimal cut-offs were 9.00 for SUVmax (p = 0.0013) and 30mm for tumour size (p = 0.0028). Patients with SUVmax > 9 and primary lesion size > 30 mm had an expected 2years-DFS of 37.5%, while this rose to 90% if the tumour was <30 mm and/or SUVmax was <9.Conclusions
In stage I-II, SUVmax and tumour size might be helpful to identify the subgroup of patients with high chance for recurrence. 相似文献17.

Background.
For patients with resected pathological stage IIIA–N2 non-small cell lung cancer (NSCLC), the role of postoperative radiotherapy (PORT) is not well defined. In this single-institutional study, we re-evaluated the effect of PORT on overall survival (OS) as well as tumor control in this subgroup of patients.Methods.
In 2003–2005, 221 consecutive patients with resected pathological stage IIIA–N2 NSCLC at our institution were retrospectively analyzed in an institutional review board–approved study. The effect of PORT on OS, cancer-specific survival (CSS), and disease-free survival (DFS) was evaluated using the Kaplan–Meier method and log-rank tests. The impact of PORT on locoregional control and distant metastasis was also analyzed.Results.
Compared with the control, patients treated with PORT had a significantly longer OS time (χ2, 3.966; p = .046) and DFS interval (χ2, 6.891; p = .009), as well as a trend toward a longer CSS duration (χ2, 3.486; p = .062). Patients treated with PORT also had a significantly higher locoregional recurrence-free survival rate (χ2, 5.048; p = .025) as well as distant metastasis-free survival rate (χ2, 11.248; p = .001). Multivariate analyses showed that PORT was significantly associated with a longer OS duration (p = .000).Conclusions.
PORT can significantly improve the survival of patients with resected pathological stage IIIA–N2 NSCLC. A prospective randomized multicenter clinical trial is ongoing. 相似文献18.

Background
The aim of this study was to describe the epidemiological and survival features of patients with glioblastoma multiforme treated in 2 health care scenarios—public and private—in Brazil.Methods
We retrospectively analyzed clinical, treatment, and outcome characteristics of glioblastoma multiforme patients from 2003 to 2011 at 2 institutions.Results
The median age of the 171 patients (117 public and 54 private) was 59.3 years (range, 18–84). The median survival for patients treated in private institutions was 17.4 months (95% confidence interval, 11.1–23.7) compared with 7.1 months (95% confidence interval, 3.8–10.4) for patients treated in public institutions (P < .001). The time from the first symptom to surgery was longer in the public setting (median of 64 days for the public hospital and 31 days for the private institution; P = .003). The patients at the private hospital received radiotherapy concurrent with chemotherapy in 59.3% of cases; at the public hospital, only 21.4% (P < .001). Despite these differences, the institution of treatment was not found to be an independent predictor of outcome (hazard ratio, 1.675; 95% confidence interval, 0.951–2.949; P = .074). The Karnofsky performance status and any additional treatment after surgery were predictors of survival. A hazard ratio of 0.010 (95% confidence interval, 0.003–0.033; P < .001) was observed for gross total tumor resection followed by radiotherapy concurrent with chemotherapy.Conclusions
Despite obvious disparities between the hospitals, the medical assistance scenario was not an independent predictor of survival. However, survival was directly influenced by additional treatment after surgery. Therefore, increasing access to resources in developing countries like Brazil is critical. 相似文献19.

Objective
The purpose of this study was to evaluate the patterns of failure, overall survival (OS), disease-free survival (DFS) and factors influencing outcome in endometrial cancer patients who presented with metastatic lymph nodes and were treated with curative intent.Methods
One hundred and twenty-six patients treated between January 1996 to December 2008 with surgery and adjuvant radiotherapy were identified from our service''s prospective database. Radiotherapy consisted of 45 Gy in 1.8 Gy fractions to the whole pelvis. The involved nodal sites were boosted to a total dose of 50.4 to 54 Gy.Results
The 5-year OS rate was 61% and the 5-year DFS rate was 59%. Grade 3 endometrioid, serous, and clear cell histologies and involvement of upper para-aortic nodes had lower OS and DFS. The number of positive nodes did not influence survival. Among the histological groups, serous histology had the worst survival. Among the 54 patients relapsed, only three (6%) failed exclusively in the pelvis and the rest of the 94% failed in extrapelvic nodal or distant sites. Patients with grade 3 endometrioid, serous and clear cell histologies did not influence pelvic failure but had significant extrapelvic failures (p<0.001).Conclusion
Majority of node positive endometrial cancer patients fail at extrapelvic sites. The most important factors influencing survival and extrapelvic failure are grade 3 endometrioid, clear cell and serous histologies and involvement of upper para-aortic nodes. 相似文献20.
