Background
We studied the relationship between intermediate criteria and overall survival (OS) in metastatic colorectal cancer (mCRC) patients who received first-line chemotherapy with bevacizumab.Patients and Methods
We assessed OS, progression-free survival (PFS), duration of disease control (DDC), the sum of the periods in which the disease did not progress, and the time to failure of strategy (TFS), which was defined as the entire period before the introduction of a second-line treatment. Linear correlation and regression models were used, and Prentice criteria were investigated.Results
With a median follow-up of 57.6 months for 216 patients, the median OS was 24.5 months (95% confidence interval [CI], 21.3-29.7). The median PFS, DDC, and TFS were 8.9 (95% CI, 8.4-9.7), 11.0 (95% CI, 9.8-12.4), and 11.1 (95% CI, 10.0-13.0) months, respectively. The correlations between OS and DDC (Pearson coefficient, 0.79 [95% CI, 0.73-0.83], determination coefficient, 0.62) and OS and TFS (Pearson coefficient, 0.79 [95% CI, 0.73-0.84], determination coefficient, 0.63) were satisfactory. Linear regression analysis showed a significant association between OS and DDC, and between OS and TFS. Prentice criteria were verified for TFS as well as DDC.Conclusion
DDC and TFS correlated with OS and are relevant as intermediate criteria in the setting of patients with mCRC treated with a first-line bevacizumab-based regimen. 相似文献2.
Background
Progression-free survival (PFS) and time to progression (TTP) have been reported to correlate with overall survival (OS) in several cancer types. To our knowledge, however, the correlation between them is unclear.Methods
A literature-based meta-analysis was performed to assess whether PFS and TTP can be considered reliable surrogate end points for OS in a phase 3 clinical trial of advanced breast cancer (ABC). The median hazard ratios of PFS/TTP and OS were analyzed by determining their nonparametric Spearman rank correlation coefficients (Rs).Results
A total of 37 trials with 38 treatment arms and 14,966 patients were selected for analysis. The Rs between the median PFS/TTP and OS was 0.405 (95% confidence interval [CI], 0.191-0.582; P = .003), and the correlation coefficient between the hazard ratios of PFS/TTP and OS was 0.555 (95% CI, 0.277-0.748; P = .003). PFS/TTP was closely correlated with OS in the trials of targeted therapy-based treatment (Rs = 0.872; 95% CI, 0.619-0.962; P = .0001) and of PFS/TTP or OS benefit (Rs = 0.753 and Rs = 0.821, respectively) for ABC.Conclusions
Both PFS and TTP can be considered valid surrogate end points for OS in the trials of targeted therapy-based treatments and clinical benefits for ABC. Further research is necessary to clarify the surrogacy of PFS/TTP for OS in other trials of targeted therapy-based treatments for ABC. 相似文献3.

Background
For patients who qualify for perioperative chemotherapy and gastrectomy for gastric cancer, the optimal timing of the postoperative chemotherapy (PC) seems equivocal. The aim of this study was to evaluate the influence of timing of PC on overall survival (OS) in patients receiving perioperative chemotherapy.Methods
Patients undergoing perioperative chemotherapy and gastrectomy with curative intent (2010–2014) were extracted from the nationwide population-based Netherlands Cancer Registry. Timing of PC was analyzed as a linear and categorical variable (<6 weeks, 6–8 weeks, and >8 weeks). Risk factors for a late start of PC (≥6 weeks), and the association between timing of PC and OS were assessed by multivariable regression analyses.Results
Among 1066 patients who underwent perioperative chemotherapy and gastrectomy, 463 (43%) patients started PC. PC was administered within 6 weeks in 208 (45%) patients, within 6–8 weeks in 155 (33%) patients, and after 8 weeks in 100 (22%) patients. A total of 419 (91%) and 351 (76%) patients finished all cycles of preoperative and PC, respectively. A late start of PC was associated with a longer hospital stay (+1 hospital day: OR 1.15, 95% CI [1.08–1.23], p < 0.001). Timing of PC was not associated with OS (6–8 weeks vs. <6 weeks, HR 1.14, 95% CI [0.79–1.65], p?=?0.471; >8 weeks vs. <6 weeks, HR 1.04, 95% CI [0.79–1.65], p?=?0.872).Conclusion
Timing of postoperative chemotherapy does not influence survival in patients receiving perioperative chemotherapy for gastric cancer. The results suggest that the early postoperative period may be safely used for recovery and optimizing patients for the start of PC. 相似文献4.

Background
Assessment of patient factors is essential for selecting later-line chemotherapy in patients with metastatic colorectal cancer (mCRC). The efficacy, prognosis, and safety of each treatment regimen according to nutritional and inflammatory status still remain to be elucidated.Patients and Methods
A total of 550 patients with mCRC who were registered in the REGOTAS study (Regorafenib versus TAS-102 as Salvage-line in patients with colorectal cancer refractory to standard chemotherapies: a multicenter observational study, UMIN 000020416) and treated with trifluridine/tipiracil (TFTD) or regorafenib as a later-line therapy were retrospectively stratified according to the modified Glasgow Prognostic Score (mGPS), which divided patients into mGPS 0 to 2 by serum albumin and C-reactive protein, and compared.Results
The median overall survival (OS) of patients with mGPS 0, 1, and 2 was 10.0 months (95% confidence interval [CI], 9.2-11.6 months), 6.5 months (95% CI, 5.3-7.1 months), and 3.9 months (95% CI, 3.3-4.9 months), respectively. The median progression-free survival (PFS) with mGPS 0, 1, and 2 was 2.5 months (95% CI, 2.1-3.0 months), 2.0 months (95% CI, 1.9-2.3 months), and 1.7 months (95% CI, 1.4-1.9 months), respectively. There were significant differences by mGPS in both OS and PFS (all P < .001). No significant differences in OS and PFS were observed between the patient groups treated with TFTD and regorafenib in each mGPS group. In patients aged ≥ 65 years with mGPS 2, the OS and PFS were worse with regorafenib than with TFTD (OS: hazard ratio, 1.45; 95% CI, 0.93-2.25; P = .097; PFS: hazard ratio, 1.57, 95% CI, 1.01-2.44; P = .047), but there were no consistent trends observed as mGPS increased. The frequency of grade 3 and more adverse events was generally similar in each mGPS group. The multivariate analyses showed that mGPS was the strongest predictive factor for OS.Conclusions
The mGPS before later-line chemotherapy is strongly correlated with survival in patients with mCRC. 相似文献5.

Introduction
Complete molecular response (CMR) and 2- and 3-year overall survival (OS) were compared for patients with newly diagnosed Philadelphia-positive acute lymphoblastic leukemia (Ph+ ALL) who had undergone front-line combination chemotherapy plus ponatinib versus combination therapy plus earlier generation tyrosine kinase inhibitors (TKIs; imatinib, dasatinib, and nilotinib).Patients and Methods
We identified 26 Ph+ ALL studies: 25 of earlier generation TKIs and 1 of ponatinib. The outcomes from studies of combination chemotherapy plus earlier generation TKIs were summarized using pooled estimates with 95% confidence intervals (CIs) from a random-effects meta-analysis. A binomial distribution was assumed to calculate the 95% CIs for the results from the single-arm combination chemotherapy plus ponatinib trial. Adjusted logistic meta-regression analyses were used to compare the outcomes between the TKI groups.Results
The percentage of patients achieving a CMR was greater with combination chemotherapy plus ponatinib (79%) than the pooled percentage of patients achieving a CMR with combination chemotherapy plus earlier generation TKIs (34%). Greater OS was observed with ponatinib compared with the pooled OS for earlier generation TKIs (2-year, 83% vs. 58%; 3-year, 79% vs. 50%). Odds ratios for ponatinib versus earlier generation TKIs were 6.09 (95% CI, 1.16-31.90; P = .034) for CMR, 3.70 (95% CI, 0.93-14.73; P = .062) for 2-year OS, and 4.49 (95% CI, 1.00-20.13; P = .050) for 3-year OS.Conclusion
Ponatinib plus chemotherapy might be associated with better outcomes than chemotherapy with earlier generation TKIs in patients with newly diagnosed Ph+ ALL. 相似文献6.

Background
We investigated whether the microsatellite instability (MSI) status affects the survival outcomes in patients with stage II/III rectal cancer who have undergone an upfront curative resection.Patients and Methods
A total of 1103 patients with curatively resected stage II/III rectal cancer who had available polymerase chain reaction-based MSI results were included in the final analysis.Results
Twenty-four (2.2%) patients in the total cohort were found to be MSI-high (MSI-H). In univariate analysis, neither disease-free survival (DFS) nor overall survival (OS) demonstrated significant differences between patients with MSI-H tumors and those with MSI-low (MSI-L) or microsatellite stable (MSS) tumors. The 5-year DFS rate was 78.0% in MSI-H patients and 69.9% in MSI-L/MSS patients (hazard ratio [HR], 0.84; 95% confidence interval [CI], 0.35-2.02; P = .689). The 5-year OS rates for MSI-H and MSI-L/MSS patients were 84.0% and 83.1%, respectively (HR, 0.86; 95% CI, 0.27-2.69; P = .790). By multivariate analysis, the MSI status did not affect either the DFS (HR, 1.00; 95% CI, 0.40-2.47; P = .994) or OS (HR, 0.85; 95% CI, 0.26-2.73; P = .778).Conclusions
MSI-H tumors are rarely observed in rectal adenocarcinoma, and the MSI status may not affect the survival outcome in patients with a resected rectal cancer. 相似文献7.

Background
Pemetrexed and bevacizumab as single agents have been approved for maintenance therapy after platinum-based induction in patients with advanced nonsquamous non–small-cell lung cancer. It is currently unknown whether bevacizumab plus pemetrexed is superior to pemetrexed alone.Patients and Methods
We conducted a nonrandomized phase II trial with 2 sequential cohorts. In the first cohort, 77 patients were treated with 4 cycles of cisplatin, bevacizumab, and pemetrexed every 3 weeks, followed by bevacizumab plus pemetrexed maintenance until progression. In the second cohort, we treated 52 patients without bevacizumab, using maintenance with pemetrexed alone. Progression-free survival (PFS), overall survival (OS), overall response rate (ORR), adverse events, and the treatment costs of the 2 cohorts were compared.Results
The median PFS from the time of registration was 6.9 months in cohort 1 and 5.6 months in cohort 2. The ORR was 62.3% in cohort 1% and 44.2% in cohort 2. The PFS (hazard ratio, 0.7; 95% confidence interval [CI], 0.5-1.0; P = .041) and ORR (odds ratio, 2.1; 95% CI, 1.0-4.3; P = .049) were better in cohort 1 than in cohort 2. No OS difference was found (hazard ratio, 1.0; 95% CI, 0.7-1.6; P = .890) after a median follow-up period of 47 months for cohort 1 and 27 months for cohort 2. The rate of grade ≥ 3 adverse events was greater in cohort 1. The treatment costs per patient were on average 1.4 times greater for cohort 1.Conclusion
The addition of bevacizumab increased the ORR and PFS, but not OS, in our nonrandomized trial. Furthermore, the addition of bevacizumab was associated with greater toxicity and higher costs. 相似文献8.

Introduction
Elderly patients account for the majority of lung cancer diagnoses but are poorly represented in clinical trials. We evaluated the overall survival (OS) of elderly patients with stage III NSCLC treated with definitive radiation compared with that of patients treated with definitive chemoradiation.Methods
We conducted a comparative effectiveness study of radiation therapy versus chemoradiation in elderly (≥70 years old) patients with stage III NSCLC not treated surgically diagnosed from 2003 to 2014; the patients were identified by using the National Cancer Database. Two cohorts were evaluated: patients (n = 5023) treated with definitive radiation (≥59.4 Gy) and patients (n = 18,206) treated with definitive chemoradiation. Chemoradiation was further defined as concurrent (radiation and chemotherapy started within 30 days of each other) or sequential (radiation started >30 days after chemotherapy). We compared OS between the treatment groups by using the Kaplan-Meier method and Cox proportional hazards regression before and after propensity score matching (PSM).Results
Treatment with chemoradiation was associated with improved OS versus that with radiation both before PSM (hazard ratio [HR] = 0.66, 95% confidence interval [CI]: 0.64–0.68, p < 0.001) and after PSM (HR = 0.67, 95% CI: 0.64–0.70, p < 0.001). Relative to concurrent chemoradiation, sequential chemoradiation was associated with a 9% reduction in the risk for death (HR = 0.91, 95% CI: 0.85–0.96, p = 0.002).Conclusions
We found that definitive chemoradiation resulted in a survival advantage compared with definitive radiation in elderly patients. Sequential chemotherapy and radiation was superior to concurrent chemoradiation. Although prospective trials are needed, this analysis suggests that chemoradiation should be strongly considered for elderly patients and the optimal sequencing of chemotherapy and radiation remains an unanswered question for this patient population. 相似文献9.

Introduction
Optimal end points in phase 2 trials evaluating salvage therapy for metastatic urothelial carcinoma are necessary to identify promising drugs, particularly immunotherapeutics, where response and progression-free survival may be unreliable. We developed a nomogram using data from phase 2 trials of historical agents to estimate the 12-month overall survival (OS) for patients to which observed survival of nonrandomized data sets receiving immunotherapies could be compared.Patients and Methods
Survival and data for major prognostic factors were obtained from phase 2 trials: hemoglobin, performance status, liver metastasis, treatment-free interval, and albumin. A nomogram was developed to estimate 12-month OS. Patients were randomly allotted to discovery:validation data sets in a 2:1 ratio. Calibration plots were constructed in the validation data set and data bootstrapped to assess performance. The nomogram was tested on external nonrandomized cohorts of patients receiving pemetrexed and atezolizumab.Results
Data were available from 340 patients receiving sunitinib, everolimus, docetaxel + vandetanib, docetaxel + placebo, pazopanib, paclitaxel, or docetaxel. Calibration and prognostic ability were acceptable (c index = 0.634; 95% confidence interval [CI], 0.596-0.652). Observed 12-month survival for patients receiving pemetrexed (n = 127, 23.5%; 95% CI, 16.2-31.7) was similar to nomogram-predicted survival (19%; 95% CI, 16.5-21.5; P > .05), while observed results with atezolizumab (n = 403, 39.0%; 95% CI, 34.1-43.9) exceeded predicted results (24.6%; 95% CI, 23.4-25.8; P < .001).Conclusion
This nomogram may be a useful tool to interpret results of nonrandomized phase 2 trials of salvage therapy for metastatic urothelial carcinoma by assessing the OS contributions of drug intervention independent of prognostic variables. 相似文献10.

Background
Given the wide adoption of human epidermal growth factor receptor 2 (HER2)-targeted therapies for advanced HER2–positive breast cancer, we studied the natural history of patients with HER2–positive breast cancer brain metastases (BCBM) over time.Patients and Methods
Patients with HER2–positive BCBM identified from a prospectively maintained database at the University of North Carolina were divided into 3 cohorts by year of BCBM diagnosis. Cohorts were selected by year of HER2–targeted therapy US Food and Drug Administration approval. Overall survival (OS), time to first metastasis, time to BCBM, and BCBM survival were estimated by the Kaplan-Meier method. Associations between OS after BCBM and clinical variables were assessed by Cox proportional hazards regression models.Results
One hundred twenty-three patients were identified. Median age was 51 years, and 58% were white and 31% African American. OS from initial breast cancer diagnosis improved over time: 3.6 years (95% confidence interval [CI], 2.8-6.1) in the 1998-2007 cohort, 6.6 years (95% CI, 4.5-8.6) in the 2008-2012 cohort, and 7.6 years (95% CI, 4.4-9.6) in the 2013-2015 cohort (P = .05). While time from initial diagnosis to first metastasis did not differ (P = .12), time to BCBM increased over time (2.6 years [95% CI, 1.3-3.5] for 1998-2007; 2.6 years [95% CI, 2.1-4.3] for 2008-2012, and 3.3 years [95% CI, 2.2-6] for 2013-2015; P = .05). Although OS from BCBM did not significantly differ by cohort, patients who received HER2–targeted therapy after BCBM had a prolonged OS (2.1 years [95% CI, 1.6-2.6] vs. 0.65 years [95% CI, 0.4-1.3]; P = .001).Conclusion
OS from initial breast cancer diagnosis significantly improved over time for patients with HER2–positive breast cancer who develop BCBM, now exceeding 7 years; survival from BCBM diagnosis may now exceed 2 years. 相似文献11.

Introduction
The expression of the CD20 on adult B-cell acute lymphoblastic leukemia (ALL-B) has generally been associated with a poor prognosis, and several studies have explored the incorporation of rituximab into the therapeutic regimen for adult ALL-B patients, with a positive effect on event-free survival (EFS).Patients and Methods
We analyzed the prognostic value of CD20 expression and the effect of rituximab for the treatment of Hispanic adult ALL-B patients. We performed a retrospective study of 152 ALL-B patients treated from 2009 to 2016. The patient characteristics and treatment outcomes were analyzed according to CD20 expression (CD20+ vs. CD20?), age group, and treatment with rituximab.Results
CD20 expression was positive for 47.7% of patients (n = 72). Excluding the patients who had received rituximab, the overall survival (OS) was greater for the CD20? patient subgroup than for the CD20+ subgroup (11.2 vs. 6.9 months; 95% confidence interval [CI], 7.43-14.9; P = .008). In the CD20+ subgroup, 10 patients (7.2%) received treatment with rituximab, with 100% reaching complete remission (CR) 4 weeks after treatment. In the 18- to 39-year age group, CD20+ patients treated with rituximab had EFS and OS that was not reached. In addition, for CD20+ patients who received with chemotherapy, EFS was 3.9 months (95% CI, 0.6-7.2 months; P = .025) and OS was 7.2 months (95% CI, 3.37-11.0; P = .013). Multivariate analysis showed that the use of rituximab was independently associated with OS and CR at 4 weeks after induction.Conclusion
CD20 expression in adult ALL-B is associated with decreased OS. Treatment with rituximab can increase OS, EFS, and CR in the 18- to 39-year age group. 相似文献12.

Background
With improved survival and longer duration of treatment, clinicians managing metastatic colorectal cancer (mCRC) increasingly consider intermittent (IC) or maintenance chemotherapy (MC), but the effect of these treatment modifications on real-world outcomes is unclear.Patients and Methods
Using a population-based cohort of mCRC patients who received combination chemotherapy, we aimed to describe the use of IC/MC and their effect on overall survival (OS).Results
Among 617 patients, 120 (19%) had periods of IC, 67 (11%) had periods of MC, and 53 (9%) had periods of both. Most (85.5%) modifications occurred in the first-line setting. The receipt of IC (median OS [mOS], 37 vs. 21 months; P < .0001) or MC (mOS, 36 vs. 24 months; P = .0015) was associated with improved mOS compared with continuous combination therapy. In multivariate analysis adjusting for age, sex, and regimen used at the time of treatment modification, IC (hazard ratio [HR], 0.52; 95% confidence interval [CI], 0.42-0.65; P < .0001), MC (HR, 0.71; 95% CI, 0.58-0.88; P = .002), and the combination (HR, 0.45; 95% CI, 0.33-0.63; P < .0001) were all associated with improved mOS. Among patients receiving MC, individuals with (HR, 0.69; 95% CI, 0.53-0.90; P = .005) and without (HR, 0.74; 95% CI, 0.55-1.00; P = .048) re-escalation to their original cytotoxic regimen had improved mOS compared with continuous therapy. The use of IC was associated with an improved OS compared with MC (HR, 0.65; 95% CI, 0.47-0.90; P = .009).Conclusion
In patients with mCRC, IC and MC are reasonable options to maintain quality of life and do not appear to negatively affect OS in carefully selected patients. 相似文献13.

Background
Afatinib is approved in the US, Europe, and several other regions for first-line treatment for epidermal growth factor receptor mutation-positive (EGFRm+) non-small-cell lung cancer (NSCLC).Patients and Methods
Treatment-naive patients with advanced EGFRm+ NSCLC were randomized to afatinib (40 mg/d) versus cisplatin/pemetrexed (LUX-Lung 3 [LL3]) or cisplatin/gemcitabine (LUX-Lung 6 [LL6]), or versus gefitinib (250 mg/d; LUX-Lung 7 [LL7]). We report subgroup analyses according to age, including 65 years or older versus younger than 65 years (preplanned; LL3/LL6) and additional cutoffs up to 75 years and older (exploratory; LL7). Progression-free survival (PFS), overall survival (OS), and adverse events (AEs) were evaluated.Results
Among the 134 of 345 (39%) and 86 of 364 (24%) patients aged 65 years and older in LL3 and LL6, median PFS was improved with afatinib versus chemotherapy (LL3: hazard ratio [HR], 0.64 [95% confidence interval (CI), 0.39-1.03]; LL6: HR, 0.16 [95% CI, 0.07-0.39]). Afatinib significantly improved OS versus chemotherapy in elderly patients with Del19+ NSCLC in LL3 (HR, 0.39 [95% CI, 0.19-0.80]). Among the 40 of 319 patients (13%) aged 75 years or older in LL7, median PFS (HR, 0.69 [95% CI, 0.33-1.44]) favored afatinib, consistent with the overall population. Afatinib-associated AEs in older patients were consistent with the overall populations.Conclusions
Subgroup analyses of the LL3, LL6, and LL7 trials show that afatinib is an effective and tolerable treatment for patients with EGFRm+ NSCLC, independent of age. 相似文献14.

Background
Invasive triple negative apocrine carcinoma (TNAC) of the breast is a rare type of triple negative breast cancer. Several studies reported significantly distinct prognosis for TNAC when compared with most of the non-apocrine triple negative (NATN) tumors. This is a case-control study reporting onoutcomes from our long-term single-center experience.Patients and Methods
We analyzed the clinicopathologic features of a series of 46 TNAC tumors treated in a 15-year period. Tumor characteristics and outcomes have been compared with a homogeneous control series of 43 NATN tumors treated during the same follow-up period. Local relapse-free survival (LRFS), distant metastases-free survival (DMFS), and overall survival (OS) have been evaluated.Results
LRFS in the TNAC group was 85% and 78% at 5 and 10 years, respectively. LRFS in the NATN group was 90% and 79% at 5 and 10 years, respectively (hazard ratio [HR], 1.14; 95% confidence interval [CI], 0.41-3.19; P = .80). DMFS in the TNAC group was 85% and 85% at 5 and 10 years, respectively. DMFS in the NATN group was 85% and 75% at 5 and 10 years, respectively (HR, 0.39; 95% CI, 0.14-1.08; P = .071). OS in the TNAC group was 86% and 83% at 5 and 10 years, respectively. OS in the NATN group was 86% and 63% at 5 and 10 years, respectively. OS was significantly better in the TNAC group (HR, 0.45; 95% CI, 0.20-0.99; P = .049).Conclusions
TNAC seems to represent a distinct group of triple negative breast cancer, characterized by a favorable long-term outcome when compared with NATN tumors. 相似文献15.

Purpose
We aimed to investigate the prognostic effect of primary tumor resection (PTR) prior to bevacizumab-based treatments in unresectable metastatic colorectal cancer (mCRC).Methods
We retrospectively collected 341 mCRC cases with unresectable metastases at diagnosis. PTR was performed in 210 cases (the surgery group) and the other patients (n?=?131) were followed without PTR (the no-surgery group). All the patients were treated with bevacizumab combined chemotherapy regimens.Results
The median progression free survival (PFS) of the surgery group was 10.4 months (95% CI: 8.9–11.9), which was significantly better than that of the no-surgery group (7.6 months, 95% CI: 6.4–8.8, P=0.000). The median overall survival (OS) of the surgery group was longer than that of the no-surgery group (27.4 months vs. 18.3 months, respectively, P=0.000). The median PFS and OS of the surgery group were 10.4 months and 28.2 months, which were significantly longer than that of the no-surgery group in Kras-mutant patients (7.8 months and 18.3 months; P=0.004, P=0.028, respectively). There was no difference in terms of PFS and OS between the surgery and the no-surgery groups in Kras-wild type patients.Conclusion
Palliative PTR may improve the survival outcomes for unresectable mCRC patients. PTR may be preferred, particularly in Kras-mutant patients. 相似文献16.

Introduction
Optimal post-remission therapy (PRT) for intermediate risk acute myeloid leukemia remains an area of ongoing research. We aimed to retrospectively compare outcomes following autologous stem cell transplantation (autoSCT) with allogeneic SCT (alloSCT) and consolidation chemotherapy (CMT) in patients with intermediate-risk karyotype AML in first complete remission.Patients and Methods
We compared overall survival (OS) and leukemia-free survival (LFS) using propensity score (PS)-adjusted analysis of patients receiving PRT with autoSCT, matched sibling (MSD) alloSCT, unrelated/mismatch (UD/MM) alloSCT, and CMT. We included patients diagnosed between 1984 and 2003 (period of autoSCT at our center) in CR1 following induction CMT and received at least 2 consolidative cycles.Results
We identified 190 patients (62 MSD-alloSCT, 18 UD/MM-alloSCT, 30 autoSCT, and 80 CMT). Baseline characteristics were used for PS calculation and were well-balanced after weight adjustment. The median follow-up for patients surviving beyond 1 year was 8.7 years. We excluded 55 patients based on PS calculation. Adjusted multivariate hazard ratio (HR), 95% confidence interval (CI) and P-value for OS, considering CMT as reference, were: MSD-alloSCT (HR, 0.4; 95% CI, 0.2-0.8; P = .009), UD/MM-alloSCT (HR, 1.5; 95% CI, 0.6-3.9; P = .363), and autoSCT (HR, 1.2; 95% CI, 0.5-3.1; P = .666), respectively. Adjusted multivariate HR, 95% CI and P-value for LFS were MSD-alloSCT (HR, 0.3; 95% CI, 0.2-0.6; P < .001), UD/MM-alloSCT (HR, 1.1; 95% CI, 0.4-2.7; P = .854), and autoSCT (HR, 0.8; 95% CI, 0.3-2.2; P = .697), respectively.Conclusion
Patients with intermediate risk-karyotype acute myeloid leukemia who underwent MSD-alloSCT in first complete remission had the best outcomes. There were no survival differences between autoSCT, UD/MM-alloSCT, and CMT. Further study incorporating molecular changes and minimal residual disease status is warranted to select appropriate patients for autoSCT. 相似文献17.

Purpose
To describe treatment patterns and clinical outcomes among postmenopausal women with metastatic ER+/HER-2? breast cancer treated with ≥ 2 lines of endocrine therapy or chemotherapy in the metastatic setting.Patients and Methods
Retrospective medical record review was conducted in Canada, the United Kingdom, Belgium, the Netherlands, Germany, Spain, and France. Baseline characteristics were assessed at the date of metastatic diagnosis. Time to progression (TTP) and overall survival (OS) were estimated by Kaplan-Meier analyses. Multivariable models were used to evaluate factors associated with disease progression.Results
Among 901 patients, the mean (standard deviation) age at metastatic diagnosis was 62.7 (9.7) years; 67.26% were initially diagnosed with metastatic disease, 66.37% had visceral disease, and 25.86% had bone metastasis only. Two-thirds of patients received endocrine therapy for first-line treatment. Fifty-nine percent received endocrine therapy, and 37.18% received chemotherapy for second-line treatment. The most common reason for stopping treatment was disease progression. Median (95% confidence interval [CI]) TTP on first-line endocrine treatment was 11.3 (10.7-12.2) months and 7.0 (6.3-7.9) months on chemotherapy. Median (95% CI) TTP on second-line endocrine therapy was 8.1 (7.5-9.1) months and 6.1 (5.4-6.8) months on chemotherapy. Median (95% CI) OS was 68.6 (52.2-83.7) months after first-line endocrine therapy and 39.7 (34.5-48.7) months after chemotherapy.Conclusion
Patients prescribed endocrine therapy had longer TTP and OS than patients prescribed chemotherapy in the first- and second-line settings. Disease progression was less than a year regardless of treatment type and line of therapy, indicating a need for treatments that delay progression without affecting quality of life among these patients. 相似文献18.

Purpose
To evaluate the prognostic role of cytoreductive nephrectomy (CN) in patients with synchronous metastatic renal-cell carcinoma (mRCC).Patients and Methods
We analyzed the electronic medical records of 294 patients with synchronous mRCC treated at Samsung Medical Center from January 2005 to December 2015. Primary and secondary end points were overall survival (OS) and cancer-specific survival (CSS), respectively. OS and CSS were estimated by the Kaplan-Meier method and compared between patients with and without CN, particularly by performing 1:1 propensity score matching. Multivariate Cox regression analysis was used to identify independent predictors of survival outcomes.Results
Among the overall population of synchronous mRCC patients, 189 patients (64.3%) underwent CN. Compared to mRCC patients without CN, those who underwent CN have a higher proportion of single metastasis (63.0% vs. 32.4%) and clear-cell histology (87.8% vs. 72.4%). In the matched cohort, the patients who underwent CN had better OS and CSS outcomes compared to those who did not undergo CN (median OS, 23.0 months vs. 11.0 months; P < .001; median CSS, 34.0 months vs. 14.0 months; P < .001). On multivariable analysis, undergoing CN, body mass index, and Heng risk score were found as significant predictive factors of both OS and CSS. In subgroup analyses stratified by Heng risk criteria, the patients who received CN had better OS and CSS in all risk groups.Conclusion
CN significantly improved survival outcomes in synchronous mRCC patients treated with targeted therapies and independently associated with prolonged survival, regardless of Heng risk criteria. 相似文献19.

Background
Elderly patients with acute myeloid leukemia (AML) have a poorer prognosis than younger ones. Several factors contribute to the poor outcomes for this patient group.Patients and Methods
This study investigated the epidemiology, clinical characteristics, treatment, and clinical outcomes of elderly Thai patients with AML. This 3-year, prospective, multicenter study was focused on Thai patients with AML aged over 60 years who were diagnosed between 2014 and 2016.Results
Of 680 patients with AML, 235 elderly patients with AML (34.6%) were identified, with a mean age of 70 ± 8 years. Using a 3-group cytogenetic risk classification (favorable, intermediate, and adverse risk), the proportions of patients in each category were 3.6%, 73.8%, and 22.6%, respectively. The median follow-up time for surviving patients was 846 days. The median overall survival (OS) of the patients was 128.2 days (range, 0-1205 days), with a 1-year OS of 13%. From a multivariate analysis, the significant factors associated with an improved long-term OS were patients with an Eastern Cooperative Oncology Group performance status 0 to 2 and those receiving intensive therapy.Conclusion
Our study confirms the high prevalence of AML in elderly patients with generally poor outcomes. Selected patients with a good performance status and those who received intensive induction treatment could have a long-term survival. 相似文献20.
