Background
This study aimed to develop and validate nomograms for predicting long-term overall survival (OS) and cancer-specific survival (CSS) in gastrointestinal stromal tumours (GISTs).Methods
Patients diagnosed with GISTs between 2004 and 2015 were selected for the study from the Surveillance, Epidemiology, and End Results (SEER) database. Patients were randomly separated into the training set and the validation set. Multivariate analysis was used on the training set to obtain independent prognostic factors to build nomograms for predicting 3- and 5-year OS and CSS. The discrimination and calibration plots were used to evaluate the predictive accuracy of the nomograms.Results
Data for a total of 5622 patients with GISTs were collected from the SEER database. Nomograms were established based on variables that were significantly associated with OS and CSS identified by the Cox regression model. The nomograms for predicting OS and CSS displayed better discrimination power than did the SEER stage and Tumour-Node-Metastasis (TNM) staging systems (7th edition) in the training set and validation set. Calibration plots of the nomograms indicated that OS and CSS closely corresponded to actual observation.Conclusions
The nomograms were able to more accurately predict 3- and 5-year OS and CSS of patients with GISTs than were existing models. 相似文献2.

Background
Almost half of patients with metastatic renal-cell carcinoma (mRCC) are classified as intermediate risk by the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) model. The aim of this study was to evaluate whether baseline C-reactive protein (CRP) levels predict overall survival (OS) in intermediate-risk group mRCC patients.Patients and Methods
Data from 107 intermediate-risk group mRCC patients receiving first-line targeted therapy were retrospectively reviewed. We evaluated the correlation between baseline CRP levels as well as other indices and OS.Results
Of the 107 patients with intermediate-risk disease, 46 patients (43%) were classified as having elevated CRP levels. The elevation of pretreatment serum CRP levels was the independent prognostic factor of OS in patients with intermediate risk (hazard ratio, 4.609; P = .001). The 1- and 3-year survival rates of patients with intermediate–nonelevated CRP were 90.0% and 64.7% compared to the favorable-risk group, at 92.1% and 68.5%, respectively. In contrast, the 1- and 3-year survival rates of patients with intermediate–elevated CRP were 80.5% and 37.4% compared to the poor-risk group, at 65.2% and 24.2%, respectively.Conclusion
Baseline CRP levels could divide mRCC patients in the intermediate-risk group into 2 prognostic subgroups. 相似文献3.

Introduction
The positive-to-resected lymph node ratio (LNR) predicts survival in many cancers, but little information is available on its value for patients with N2 NSCLC who receive postoperative radiotherapy (PORT) after resection. We tested the applicability of prognostic scoring models and heat mapping to predict overall survival (OS) and cancer-specific survival (CSS) in patients with resected N2 NSCLC and PORT.Methods
Our test cohort comprised patients identified from the Surveillance, Epidemiology, and End Results database with N2 NSCLC who received resection and PORT in 2000–2014. Prognostic scoring models were developed to predict OS and CSS using Cox regression; heat maps were constructed with corresponding survival probabilities. Recursive partitioning analysis was applied to the Surveillance, Epidemiology, and End Results data to identify the optimal LNR cutoff point. Models and cutoff points were further tested in 183 similar patients treated at The University of Texas M. D. Anderson Cancer Center in 2000–2015.Results
Multivariate analyses revealed that low LNR independently predicted better OS and CSS in patients with resected N2 NSCLC who received PORT.Conclusions
LNR can be used to predict survival of patients with resected N2 NSCLC followed by PORT. This approach, which to our knowledge is the first application of heat mapping of positive and negative lymph nodes, was effective in estimating 3-, 5-, and 10-year OS probabilities. 相似文献4.

Background
Biomarkers to guide treatment in metastatic renal-cell carcinoma (mRCC) are lacking. We aimed to investigate the association between pretreatment neutrophil-to-lymphocyte ratio (NLR) and outcome of patients with mRCC receiving nivolumab.Patients and Methods
Through retrospective chart review, we identified 38 patients with mRCC treated with standard-of-care nivolumab between 2015 and 2016 at Winship Cancer Institute of Emory University. NLR was determined from complete blood count collected before starting treatment, and imaging was performed to assess progression. The NLR cutoff value of 5.5 was determined by log-rank test, and the univariate association with overall survival (OS) or progression-free survival (PFS) was assessed by the Cox proportional hazard model and Kaplan-Meier method.Results
The 38 patients had a median age of 69 years. The PFS and OS for all patients at 12 months was 54% and 69%, respectively. The median PFS was 2.6 months in the high NLR group but not reached in the low NLR group. Low NLR was strongly associated with increased PFS with hazard ratio of 0.20 (95% confidence interval, 0.07-0.64; P = .006). The median OS was 2.7 months in the high NLR group but not reached in the low NLR group. Low NLR was significantly associated with a prolonged OS with hazard ratio of 0.06 (95% confidence interval, 0.01-0.55; P = .012).Conclusion
Pretreatment NLR < 5.5 is associated with superior PFS and OS. NLR is a biomarker that can inform prognosis for patients with mRCC and should be further validated in larger cohorts and in prospective studies. 相似文献5.
Introduction
The introduction of active new agents, such as small molecules and checkpoint inhibitors, for the treatment of metastatic renal-cell cancer (mRCC) is associated with a relevant increase in costs, and it is therefore important to strike a balance between the costs of treatment and the added value represented by the improvement of the clinical parameters of interest such as progression-free survival (PFS) and overall survival (OS).Methods
This analysis was conducted to assess the pharmacologic costs of second-line treatments for mRCC and was restricted to pivotal phase 3 randomized controlled trials (RCTs) used as second-line therapy.Results
Our analysis evaluated 4 phase 3 RCTs including a total of 2454 patients. The European Society for Medical Oncology Magnitude of Clinical Benefit Scale (ESMO-MCBS) reached high scores (grade 5) for the CheckMate 025 trial, medium scores (grade 3) for the RECORD-1 and AXIS trials, and low scores (grade 2) for the INTORSECT trial. When we combined the costs of therapy with the measure of efficacy represented by the PFS and OS, we found that the most relevant increase of costs was associated with the use of nivolumab but that it differed according to the difference in costs in terms of life gained, with the highest costs per week of PFS gained (€11,960) but the lowest cost for month of OS gain (€1772).Conclusion
When pharmacologic costs of drugs are combined with the measure of efficacy represented by the OS, nivolumab is a cost-effective second-line treatment for patients with mRCC. 相似文献6.

Background
The International mRCC (metastatic renal cell carcinoma) Database Consortium (IMDC) is the standard classification for mRCC. We aimed to evaluate the outcomes of a large cohort of patients with an intermediate or a poor prognosis treated with sunitinib using a different cutoff point for IMDC to improve the classification.Patients and Methods
Patients with an intermediate or a poor prognosis according to the IMDC criteria and treated with sunitinib were included in the present study. A new cutoff point was used to categorize the patients. The new score was validated in an independent cohort of patients.Results
A total of 457 patients were included in the present study. Significant differences in overall survival (OS) were highlighted regarding the number of prognostic factors. Three categories were identified according to the presence of 1 (ie, favorable-intermediate group), 2 (ie, real-intermediate group), and > 2 (ie, poor group) factors. The corresponding median OS periods were 32.9, 20.0, and 8.9 months, with significant differences among the groups. The validation cohort included 389 patients. The median OS period for the favorable-intermediate group, real-intermediate group, and poor group was 34.3, 19.4, and 9.0 months, respectively, with confirmed significant differences among the groups.Conclusion
Our analysis revealed significant differences among patients with an intermediate prognosis using the IMDC prognostic factors. Further investigations to optimize the use of available and upcoming therapies are required. 相似文献7.

Purpose
Male breast cancer (MBC) represents < 1% of breast cancer patients, and limited data exists regarding metastatic MBC. To better characterize this patient subset, we performed a population-based study examining prognostic factors among patients with stage IV MBC.Methods
Patients with stage IV MBC diagnosed between 1988 and 2012 were selected from the Surveillance, Epidemiology, and End Results database. Prognostic factors for overall survival (OS) and cause-specific survival (CSS) were evaluated.Results
Overall, 394 patients had metastatic disease meeting inclusion criteria. The median follow-up was 21 months. The 5-year OS and CSS rates were 21.1% and 38.3%, respectively. Of those with known progesterone receptor (PR) status, 52% were PR-positive, which was associated with better OS (P < .001) and CSS (P = .003). Overall, 197 patients (50%) received surgery for the primary tumor, and 197 (50%) did not. Patients undergoing surgery had longer median CSS than those who did not (36 vs. 21 months; P < .001). Additional factors that correlated with prolonged OS and CSS were smaller tumor size (≤ 2 cm; P < .05) and younger age (≤ 65 years; P < .05). In multivariate analysis, smaller tumor size, PR-positivity, younger age, and resection of the primary tumor were associated with longer OS and CSS (P < .05).Conclusions
Although stage IV MBC has poor OS and CSS, patients with PR-positive disease, younger age (≤ 65 years), tumor size ≤ 2 cm, or who undergo surgery of the primary tumor have better OS and CSS. This is the largest study of stage IV MBC to date, and these findings address some of the questions regarding this rare presentation of breast cancer. 相似文献8.

Background
Recent studies have revealed significant relationships between the lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) and survival in various cancers. The purpose of this study was to confirm whether the LMR, NLR, and PLR have prognostic values, independent of clinicopathological criteria, in patients undergoing curative resection for esophageal cancer.Methods
The LMR, NLR and PLR were calculated in 147 consecutive patients who underwent curative esophagectomy between January 2006 and December 2014. Receiver operating characteristics (ROC) curve analysis was conducted to identify the optimal cutoff values of each biomarkers.Results
In multivariate analysis for cancer-specific survival (CSS), pTNM stage (p < 0.0001) and low LMR (p = 0.0081) were selected as independent prognostic factor. Similarly, pTNM stage(p < 0.0001) and low LMR (p = 0.0225) were found to be independent prognostic factor for overall survival (OS). There was no significant relationship between LMR, NLR and PLR and survival in patients with stage I or II, however, significant relationships between LMR and CSS or OS were observed in patients with stage III esophageal cancer.Conclusions
LMR can be used as a novel predictor of postoperative CSS and OS in patients with esophageal cancer and that it may be useful in identifying patients with a poor prognosis even after radical esophagectomy. 相似文献9.

Purpose
To investigate the short- and long-term outcomes of liver first approach (LFA) in patients with synchronous colorectal liver metastases (CRLM), evaluating the predictive factors of survival.Methods
Sixty-two out of 301 patients presenting with synchronous CRLM underwent LFA between 2007 and 2016. All patients underwent neoadjuvant chemotherapy. After neoadjuvant treatment patients were re-evaluated according to the Response Evaluation Criteria in Solid Tumors (RECIST). Liver resection was scheduled after 4–6 weeks. Changes in non-tumoral parenchyma and the tumor response according to the Tumor Regression Grade score (TRG) were assessed on surgical specimens. Primary tumor resection was scheduled 4–8 weeks following hepatectomy.Results
Five patients out of 62 (8.1%) showed “Progressive Disease” at re-evaluation after neoadjuvant chemotherapy, 22 (35.5%) showed “Stable Disease” and 35 (56.5%) “Partial Response”; of these latter, 29 (82%) showed histopathologic downstaging. The 5-year survival (OS) rate was 55%, while the 5-year disease-free survival (DFS) rate was 16%. RECIST criteria, T-stage, N-stage and TRG were independently associated with OS. Bilobar presentation of disease, RECIST criteria, R1 margin and TRG were independently associated with DFS. Patients with response to neoadjuvant chemotherapy had better survival than those with stable or progressive disease (radiological response 5-y OS: 65% vs. 50%; 5-y DFS: 20% vs. 10%; pathological response 5-y OS: 75% vs. 56%; 5-y DFS: 45% vs. 11%).Conclusions
LFA is an oncologically safe strategy. Selection is a critical point, and the best results in terms of OS and DFS are observed in patients having radiological and pathological response to neoadjuvant chemotherapy. 相似文献10.

Purpose
To determine the therapeutic value of lymph node dissection (LND) during cytoreductive nephrectomy (CN) and assess predictors of cancer-specific survival (CSS) in metastatic renal-cell carcinoma.Patients and Methods
We identified 293 consecutive patients treated with CN at 4 academic institutions from March 2000 to May 2015. LND was performed in 187 patients (63.8%). CSS was estimated by the Kaplan-Meier method for the entire cohort and for a propensity score–matched cohort. Cox proportional hazards regression was used to evaluate CSS in a multivariate model and in an inverse probability weighting–adjusted model for patients who underwent dissection.Results
Median follow-up was 12.6 months (interquartile range, 4.47, 30.3), and median survival was 15.9 months. Of the 293 patients, 187 (63.8%) underwent LND. One hundred six patients had nodal involvement (pN+) with a median CSS of 11.3 months (95% confidence interval [CI], 6.6, 15.9) versus 24.2 months (95% confidence interval, 14.1, 34.3) for pN? patients (log-rank P = .002). The hazard ratio for LND was 1.325 (95% CI, 1.002, 1.75) for the whole cohort and 1.024 (95% CI, 0.682, 1.537) in the propensity score–matched cohort. Multivariate analysis revealed that number of positive lymph nodes (P < .001) was a significant predictor of worse CSS.Conclusion
For patients with metastatic renal-cell carcinoma undergoing CN with lymphadenectomy, the number of nodes positive was predictive of survival at short-term follow-up. However, nonstandardized lymphadenectomy only provided prognostic information without therapeutic benefit. Prospective studies with standardized templates are required to further ascertain the therapeutic value of LND. 相似文献11.

Background
Major resection (MR) is recommended for cases with T2 finding after local excision (LE) of early rectal cancer, but the revision procedure is accompanied with high morbidity. We evaluated the oncological safety of LE followed by adjuvant radiotherapy as a rectum-preserving alternative to MR for T2 early rectal cancer.Methods
A total of 3786 patients with T2N0M0 rectal adenocarcinoma between 1998 and 2013 were included from the SEER database. Survival rates were compared using the Kaplan-Meier method with a log-rank test, and multivariate analyses were performed using Cox proportional regression models.Results
Of these patients included, 429 (11.3%) treated with LE alone (LE group), 3067 (81.0%) treated with MR (MR group), and 290 (7.7%) treated with LE followed by adjuvant radiotherapy (LE + adjuvant RT group). The 5-year cancer specific survival (CSS) rate and 5-year overall survival (OS) rate were significantly lower in LE patients group than those in MR patients group (70.5% vs. 81.8%, P < 0.001; 57.3% vs. 72.3%, P < 0.001). The 5-year CSS rate and 5-year OS rate were similar between LE + adjuvant RT and MR groups (78.4% vs. 81.8%, P = 0.975, and 70.7% vs. 72.3%, P = 0.311, respectively). Multivariate Cox regression revealed that treatment strategies, age and CEA status were independently associated with CSS and OS. After age adjustment, LE was associated with reduced CSS (using MR as a reference, HR, 1.784; P < 0.001) and reduced OS (HR, 1.739; P < 0.001). However, CSS and OS related to LE + adjuvant RT of T2 rectal cancer group weren't be affected (HR, 0.994; P = 0.962 and HR, 0.904; P = 0.302, respectively).Conclusions
When MR is inappropriate for T2 early rectal cancer patients because of patients refusal or co-morbidities, LE + adjuvant RT can provide acceptable levels of long-term survival. 相似文献12.

Background
Sunitinib malate, a targeted tyrosine kinase inhibitor, is standard of care for metastatic renal cell carcinoma (mRCC) and serves as the active comparator in several ongoing mRCC clinical trials. In this analysis we report benchmarks for clinical outcomes on the basis of International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) risk groups for patients treated with sunitinib for mRCC in a first-line setting.Materials and Methods
A retrospective analysis was performed on data from sunitinib-treated patients (n = 375) in the pivotal phase III trial of sunitinib versus interferon-α as first-line treatment for mRCC. Objective response rates (ORRs) were determined from independently reviewed radiologic assessments. The Kaplan–Meier method was used to estimate median progression-free survival (PFS) and median overall survival (OS) according to patient risk group.Results
Median PFS (95% confidence interval [CI]) was 14.1 (13.4-17.1), 10.7 (10.5-12.5), 2.4 (1.1-4.7), and 10.6 (8.1-10.9) months in sunitinib-treated patients in the IMDC favorable (n = 134), intermediate (n = 205), poor (n = 34), and intermediate + poor (n = 239) risk groups, respectively. Median OS (95% CI) was 23.0 (19.8-27.8), 5.1 (4.3-9.9), and 20.3 (16.8-23.0) months in sunitinib-treated patients in IMDC intermediate, poor, and intermediate + poor risk groups, respectively, and was not reached in the favorable risk group (>50% of patients were alive at data cutoff). ORRs (95% CI) was 53.0% (44.2%-61.7%), 33.7% (27.2%-40.6%), 11.8% (3.3%-27.5%), and 30.5% (24.8%-36.8%) in sunitinib-treated patients in IMDC favorable, intermediate, poor, and intermediate + poor risk groups, respectively.Conclusion
Results of this retrospective analysis show differences in patient outcomes for PFS, OS, and ORR on the basis of IMDC prognostic risk group assignment for patients with mRCC. 相似文献13.

Background
We characterized clinical outcomes of patients with metastatic renal cell carcinoma (mRCC) treated with sunitinib who were long-term responders (LTRs), defined as patients having progression-free survival (PFS) > 18 months.Patients and Methods
A retrospective analysis of data from 5714 patients with mRCC treated with sunitinib in 8 phase II/III clinical trials and the expanded access program. Duration on-study and objective response rate (ORR) were compared between LTRs and patients with PFS ≤ 18 months (“others”). PFS and overall survival (OS) were summarized using Kaplan–Meier methodology.Results
Overall, 898 (15.7%) patients achieved a long-term response and 4816 (84.3%) patients did not achieve long-term response. The median (range) duration on-study was 28.6 (16.8-70.7) months in LTRs and 5.5 (0-68.8) months in others. ORR was 51% in LTRs versus 14% in others (P < .0001). Median PFS in LTRs was 32.11 months and median OS was not reached. LTRs had higher percentage of early tumor shrinkage ≥ 10% at the first scan (67.1% vs. 51.2%; P = .0018) and greater median maximum on-study tumor shrinkage from baseline (?56.9 vs. ?27.1; P < .0001) versus others. White race, Eastern Cooperative Oncology Group performance status 0, time from diagnosis to treatment ≥ 1 year, clear cell histology, no liver metastasis, lactate dehydrogenase ≤ 1.5 upper limit of normal (ULN), corrected calcium ≤ 10 mg/dL, hemoglobin greater than the lower limit of normal, platelets less than or equal to ULN, body mass index ≥ 25 kg/m2, and low neutrophil-to-lymphocyte ratio were associated with LTR.Conclusion
A subset of patients with mRCC treated with sunitinib achieved long-term response. LTRs had improved ORR, PFS, and OS. 相似文献14.

Introduction
In metastatic renal-cell carcinoma (mRCC), physicians have a plethora of therapeutic choices, with the latest addition of checkpoint inhibitors. However, many questions regarding the best use of the respective drugs remain unanswered. Therefore, it is important to examine and summarize the outcome of real-world experiences to understand the practical value of the various drugs in daily use and foster optimal treatment algorithms for patients with renal-cell carcinoma. We sought to describe the pattern of care in mRCC under circumstances with access to all therapeutic options for patients.Patients and Methods
We examined the outcome of patients with mRCC who were treated at 8 major centers in Switzerland, mainly with vascular endothelial growth factor–targeted therapy and mammalian target of rapamycin inhibitors. Data from 110 patients with mRCC who had undergone more than one systemic therapy were collected and analyzed. We assessed the pattern of care for patients with mRCC in an unrestricted health care system and outcomes with regard to the respective treatment sequences. We also studied the compliance of individual therapies with published guidelines and correlated the adherence to outcome. Finally, immediate versus deferred treatment and the number of received therapeutic drug lines were analyzed.Results
Median survival of patients treated with targeted agents for mRCC was 2.0 years.Conclusion
Exposure to more than 2 lines of systemic drugs did not improve outcome of patients with mRCC. 相似文献15.

Purpose
To identify the impact of albumin–globulin ratio (AGR) on pathologic and survival outcomes in patients with upper tract urothelial carcinoma (UTUC) after radical nephroureterectomy (RNU).Patients and Methods
We retrospectively reviewed medical records of 620 patients treated with RNU for UTUC at our institution. Logistic regression analysis was used to evaluate the relation between low AGR (<1.45) and adverse pathologic features. Kaplan-Meier curves were used to estimate recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS) probabilities between 2 groups. Univariable and multivariable Cox regression models were performed to address prognostic factors related to RFS, CSS, and OS.Results
Of the 620 patients, 323 (52.1%) had AGR < 1.45. During a median follow-up of 50.0 months (interquartile range, 28-78 months), 277 (44.7%) experienced disease recurrence and 194 (31.3%) died of disease. The results showed that low AGR was significantly associated with adverse pathologic features (all P < .05). Kaplan-Meier analysis showed that compared to those with high AGR (≥1.45), patients with low AGR had poorer RFS, CSS, and OS (P < .001). After adjusting for the confounding clinicopathologic factors, multivariate analyses showed that AGR < 1.45 independently predicted poor RFS (hazard ratio [HR] = 1.321, P = .029), CSS (HR = 1.503, P = .010) and OS (HR = 1.403, P = .015).Conclusion
Low preoperative AGR is an independent predictor of worse pathologic and oncologic outcomes in patients with UTUC after RNU. The application of AGR as an easily assessed blood-based biomarker in predicting the prognosis of patients with UTUC is promising. 相似文献16.
Purpose
To assess the pharmacologic costs of second-line treatments for metastatic renal-cell cancer (mRCC).Methods
The present evaluation was restricted to pivotal phase 3 randomized controlled trials in second-line for mRCC. We calculated the pharmacologic costs necessary to get the benefit in progression-free survival and overall survival (OS) for each trial. The costs of drugs are at the pharmacy of our hospital and are expressed in euros.Results
Our analysis evaluated 5 phase 3 randomized controlled trials including 3112 patients. The lowest cost per month of progression-free survival and OS gained was associated with the use of cabozantinib (€2006 and €1473, respectively), while everolimus had the highest cost per month of OS gained (€28,590).Conclusion
Combining pharmacologic costs of drugs with the measure of efficacy represented by OS, cabozantinib is a cost-effective second-line treatments for patients with mRCC. 相似文献17.

Background
The optimal timing of targeted therapy (TT) initiation for metastatic renal-cell carcinoma (mRCC) is not clear. We used a nationwide cancer registry to determine clinical and social factors associated with delayed TT and to evaluate the association of a delayed approach with overall survival (OS).Patients and Methods
We performed a retrospective observational study utilizing the National Cancer Data Base from 2006 to 2012 for patients diagnosed with mRCC (clear-cell histology) treated with cytoreductive nephrectomy and TT. Time to initiation of TT was defined as early (within 2 months), moderately delayed (2-4 months), delayed (4-6 months), and late (> 6 months).Results
Of the 2716 patients included in the analysis, the median (interquartile range) time from diagnosis to initiation of TT was 2.1 (1.3-3.23) months. A total of 1255 patients (46.2%) had early TT, 1072 patients (39.5%) had moderately delayed TT, 284 patients (10.5%) had delayed TT, and 105 patients (3.9%) had late TT. Delay in TT initiation was not independently associated with OS in multivariable analysis. The time interval from diagnosis to TT initiation was not correlated with time from initiation of TT to death (r = 0.04, P = .08).Conclusion
We found that delayed initiation of TT was not an independent predictor of worse OS. Although this study is subject to limitations of observation study design and selection bias, the results are consistent with the notion that in carefully selected patients, outcomes might not be compromised with initial observation. 相似文献18.

Background
The purpose of the present retrospective analysis was to describe the trends in exposure to multiple lines of treatment and overall survival (OS) in patients with metastatic renal cell carcinoma (mRCC) who started therapy in 2 different periods (period 1, 2004-2010; and period 2, 2011-2017).Patients and Methods
The proportion of patients who received subsequent lines of treatment after disease progression was compared between the 2 groups. OS was measured from the start of first-line treatment for metastatic disease to death or the last follow-up examination. Both univariate and multivariate analyses were performed.Results
A total of 500 patients were included in the study; 274 started treatment in period 1 and 226 in period 2. Of those patients who stopped first-line treatment because of disease progression, the patients in period 2 had a greater conditional probability to receive second- and third-line treatment compared with patients in period 1 (77.2% vs. 63.7%; odds ratio [OR], 1.93; 95% confidence interval [CI], 1.20-3.11; P = .0065; and 69.6% vs. 48.1%; OR, 2.48; 95% CI, 1.40-4.40; P = .002, respectively). The median OS improved from 22.8 months for patients in period 1 to 38.2 months for patients in period 2 (univariate analysis: hazard ratio, 0.65; 95% CI, 0.50-0.83; P = .001).Conclusion
Patients who started treatment during the past 5 years were exposed to a greater number of treatment lines compared with patients treated before 2011. Our data suggest that the increase of treatment options available and clinician expertise could be associated with better outcomes. 相似文献19.

Background
Current guidelines recommend that metastatic gastric cancer should not be treated with surgery unless this is required for symptom control. We hypothesized that patients with mismatch repair deficiency (MMRd) gastric cancer and metastatic disease detected at the timepoint of surgical resection would have superior survival compared to patients with MMRd cancers in the same setting.Methods
Clinicopathological details and survival data were collected from prospective databases at two large European centers on patients who had undergone surgery and were diagnosed with synchronous stage IV gastric cancer (distant lymph nodes, positive peritoneal cytology, peritoneal, and distant metastases) at the timepoint of surgery. Resection specimens were tested for the presence of microsatellite instability using a standard 5 mononucleotide repeat panel.Results
One hundred and seventy six patients with resected stage IV gastric cancer were identified. 14/176 (8.0%) had MSI-H (high) disease. There was no significant difference between the clinical and pathological characteristics of MSI and microsatellite stable (MSS) patients. No differences in the type of metastases were observed between MSI and MSS groups. Patients who were MSI-H had superior OS compared to MSS patients (median OS 15.9 vs. 8 months, p = 0.023). However, in Cox regression multivariate analysis only liver and peritoneal metastases were independent predictors of survival.Conclusions
Surgically treated patients with MSI-H stage IV gastric cancer have a better survival than patients with MSS gastric cancer. Further analysis of the role of surgery in MSI stage IV GC is required. 相似文献20.
