Kaplan-Meier survival analysis between ARMS expression and the overall survival in melanoma patients. Patients with negative-, weak-, or moderate-ARMS express
As I understand from a comment, the OP didnt realize that the Kaplan-Meier estimate is nothing but the empirical estimate of the survival function in case when there is no censoring.. Let me tell a word about that. Consider two independent random variables $X$ and $Y$ with continuous distributions, and independent replicated observations $x_i$ and $y_i$, $i=1, \ldots, n$. In the context of the Kaplan-Meier estimate, $Y$ is considered as the censoring variable and one observes the minima $t_i=\min(x_i,y_i)$ together with the indicators $\delta_i={\boldsymbol 1}_{x_i \leq y_i}$, independent replicated observations of $T=\min(X,Y)$ and $\Delta={\boldsymbol 1}_{X \leq Y}$ respectively.. Note that $\Pr(T ,t)=\Pr(X,t)\Pr(Y,t)$, that is to say $\boxed{S^T(t)=S^X(t)S^Y(t)}$ by denoting $S^T$, $S^X$ and $S^Y$ the survival functions of $T$, $X$ and $Y$ respectively.. The usual empirical survival function $\hat{S}^T$ of $T$ is available from the data. When seeking estimates $\hat{S}^X$ and $\hat{S}^Y$ of ...

A plot of the Kaplan-Meier estimator is a series of declining horizontal steps which, with a large enough sample size, approaches the true survival function for that population. The value of the survival function between successive distinct sampled observations (clicks) is assumed to be constant. An important advantage of the Kaplan-Meier curve is that the method can take into account some types of censored data, particularly right-censoring, which occurs if a patient withdraws from a study, is lost to follow-up, or is alive without event occurrence at last follow-up. On the plot, small vertical tick-marks indicate individual patients whose survival times have been right-censored. When no truncation or censoring occurs, the Kaplan-Meier curve is the complement of the empirical distribution function. In medical statistics, a typical application might involve grouping patients into categories, for instance, those with Gene A profile and those with Gene B profile. In the graph, patients with Gene ...

This prospective cohort study was designed to examine the prognostic role of ambulatory peripheral and central SBP, PP, PWV, and AIx recordings for cardiovascular events and mortality in hemodialysis patients. The main finding was that cumulative freedom from primary end point was significantly shorter with higher quartiles of ambulatory PWV and AIx(75), but was not different for quartiles of predialysis SBP, 48-hour peripheral SBP, and 48-hour central SBP. Similarly, the HR for all-cause mortality, cardiovascular mortality and the combined outcome of cardiovascular events were similar for quartiles of predialysis SBP, 48-hour peripheral SBP and 48-hour central SBP, but were progressively increasing with higher quartiles of ambulatory PWV and ambulatory AIx(75). Increasing quartiles of 48-hour central PP displayed higher HR for primary end point, but nonsignificant trends toward increased cardiovascular events and mortality. In multivariate Cox-regression analysis 48h-ambulatory-PWV was the only ...

Figure 4. TNFR1 expression inversely correlates with survival over the full range of the survival curve over all 143 samples including all primary tumor groups. In all 4 graphs, survival is defined as the number of months each patient survived following the first diagnosis of bone metastasis. A, the total set of 143 samples with known survival data was subdivided into 4 quartiles based on survival time. The mean and median TNFR1 expression in the 4 quartiles descends over the shortest to the longest survivors. The Mann-Whitney test was applied to medians of the lowest (x ≤ 5) and highest (x ≥ 38) survival quartiles. The Kruskal-Wallis test was conducted on the medians of 4 groups of samples. B, this graph depicts the Kaplan-Meier survival curves in the total set of 143 samples, using the median of TNFR1 expressions as the cut point to create the high expressing (high) and the low expressing (low) patients groups.

Objective: APBB1IP is a Rap1-binding protein that mainly acts as a regulator of leukocyte recruitment and pathogen clearance through complement-mediated phagocytosis. However, the role of APBB1IP in tumor immunity remains unclear. This study was carried out to evaluate the prognostic landscape of APBB1IP in pan-cancer analysis and investigate the relationship between APBB1IP expression and immune infiltration.. Methods: We explored the expression pattern and prognostic value of APBB1IP in pan-cancer analysis through Kaplan-Meier Plotter and multiple databases, including TCGA, Oncomine. We then assessed the correlation between APBB1IP expression and immune cell infiltration using the TIMER database. Furthermore, we identified the proteins that interact with APBB1IP and performed epigenetic and transcriptional analyses. Multivariate Cox regression analyses were applied to construct a prognostic model, which consisted of APBB1IP and its interacting proteins, based on the lung cancer cohorts from ...
Introduction: For patients with nonfunctioning pNET ≥20 mm in size without distant metastasis, complete surgical resection is recommended as the primary curative strategy. Effective follow‐up programs are designed to detect recurrence at an early stage, given that treatment of limited disease has the most favorable outcome. However, data on post‐curative surgical recurrence remains limited, making it challenging to determine the best follow‐up strategy and to detect the best treatment options as an adjuvant therapy for selected patients ...
Kaplan-Meier curves from RCTs exhibiting non-proportional hazards are seen in the literature,101516 but relatively few investigators tackle this problem in their reports, and fewer still take it into account when estimating treatment effects. Non-proportionality could be caused by the mechanism of action of a treatment, supported by biological evidence; a biomarker, where the Kaplan-Meier curves do have proportional hazards when analysed separately according to concentrations of the marker2; or treatments with long term benefits but high early mortality. In other cases, it might simply be a chance finding in a small trial or influenced by the trial design.. In some immunotherapy trials for advanced cancer, no difference is seen in median PFS.1 On closer inspection, the timing of the first radiological assessment scan for progression coincides with the median PFS, indicating that progression actually occurred before this time in many patients; the timing of the first scan is too late. ...
I am dealing with survey data from firms to conduct survival analysis. I am going to estimate with Kaplan - Meier and a Cox Regression. I face rigth censored data as usual but I have to deal with the different starting operation year of each firm. The survey covers 2006 - 2015. Some firms start operations on 2006 and survive until end or close before they get censored. But then some others starts on 2007, 2008 or even 2014. An easy way to deal with would be to just consider firms that started on 2006 and followed them until 2015. But then I would lose 80% of data. The literature I says it shouldnt be a problem if I take in consideration the less exposed time to risk. As happens with medical survival analysis when you have patients information. I wonder if I should also control in my model the effect of the year they started operations. Or that wouldn´t be rigth at all. Thanks in advance!. ...
Endpoints:. - Response Rate, Disease control rate, The duration of overall response, Overall survival, PFS, Time to treatment failure, Quality of Life, Incidence of AEs, Frequency and nature of serious adverse reactions (SADRs), Premature withdrawals. Statistical methods:. Assuming a randomization ratio of 1:1, 282 deaths are required in order to achieve a power of 80% of detecting a hazard ratio of 0.72 in favour of one of the two sequences, translating in an increase of median survival time from 10 to 14 months, with a type I error of 5%, two-sided, using the Mantel-Cox version of the log-rank test. With a uniform accrual period of 3 years and a follow-up of 18 months, about 350 patients will be needed to reach the target number of events.. All statistical analyses will be based on an intention-to-treat approach. CONSORT rules will be applied to describe study flow and protocol deviations.. All OS and PFS curves will be drawn with the Kaplan-Meier method. Results will be presented as Hazard ...
In biomedical research, especially in the fields of epidemiology or oncology, one of the most common outcome under assessment is the time to an event of interest (also called failure), namely survival time. The considered event is often death, but could be anything else such as cancer relapse or progression instead. The vast majority of survival analyses have extensively been using Kaplan-Meier (KM) estimates, log-rank tests and Cox proportional hazards (CoxPH) models, all of which we will describe shortly.

Aim: To evaluate if baseline serum lipids are associated with islet graft survival in type 1 diabetes mellitus islet transplant (ITx) recipients.. Research design and methods: Baseline fasting lipid profile was collected from 44 ITx recipients. Comparisons were performed between subjects below and above the median values of each lipid fraction. Differences in outcomes were compared by Kaplan-Meier curves and Cox-regression analysis.. Results: Subjects with baseline fasting plasma triglycerides and VLDL-cholesterol above median had shorter islet graft survival (triglycerides: 39.7±6.1 vs. 61.3±6.6 months, P=0.029 and VLDL: 41.5±5.7 vs. 62.8±7.3 months, P=0.032). Total, LDL and HDL-cholesterol didnt influence islet function. Triglycerides (OR=2.97, 95%CI=1.03-8.52, P=0.044) maintained its association with graft failure after adjustments for confounders.. Conclusions: Higher baseline triglycerides are associated with earlier decline in islet graft function. Prospective clinical trials should ...

Purpose: To optimize neuroblastoma treatment stratification, we aimed at developing a novel risk estimation system by integrating gene expression-based classification and established prognostic markers.. Experimental Design: Gene expression profiles were generated from 709 neuroblastoma specimens using customized 4 × 44 K microarrays. Classification models were built using 75 tumors with contrasting courses of disease. Validation was performed in an independent test set (n = 634) by Kaplan-Meier estimates and Cox regression analyses.. Results: The best-performing classifier predicted patient outcome with an accuracy of 0.95 (sensitivity, 0.93; specificity, 0.97) in the validation cohort. The highest potential clinical value of this predictor was observed for current low-risk patients [5-year event-free survival (EFS), 0.84 ± 0.02 vs. 0.29 ± 0.10; 5-year overall survival (OS), 0.99 ± 0.01 vs. 0.76 ± 0.11; both P , 0.001] and intermediate-risk patients (5-year EFS, 0.88 ± 0.06 vs. 0.41 ± ...

A novel finding with potential prognostic impact relates to the observation that 45/149 (30%) of M-CLL cases exhibited high expression of UGT2B17 and displayed poor clinical outcome (P,0.001, Online Supplementary Figure S1). Since the majority of these cases were negative for CD38 expression (134/149, 90%), carried only favorable genomic lesions (del(13q) or no recurrent aberrations (133/145, 92%) and did not display mutations in TP53 (145/149, 97%), NOTCH1 (139/142, 98%) or SF3B1 (140/143, 98%), quantification of UGT2B17 mRNA expression identified a subgroup of progressive M-CLL cases (31/120, 26%) for which, to date, no established prognostic marker has been successful in identifying (Figure 1C). Notably, within M-CLL, high UGT2B17 expression remained as the strongest independent molecular prognostic marker for OS in multivariate analysis (Online Supplementary Table S2). Further evaluation of UGT2B17 expression on clinical outcome in subgroups of CLL with favorable prognosis revealed high ...
We read with great interest a recent article by Dhooghe et al. (1) on long-term effects of childbirth on MS. Unfortunately, the study appears to have been subject to important biases (in addition to those discussed by the authors themselves, including, notably, confounding). The first bias - namely, the left-truncation bias (2) - has to do with the fact that to be included in the analyses, patients had to be under regular care at the referral centre in 2005-2007. Thus, patients who had the onset of MS in 1975, for example, would only be included in the study sample if they survived at least until 2005. Because MS survival is correlated with the rate of disease progression, those who were included represent a subpopulation with a slower rate of progression than among all MS patients (if they were followed from the onset of MS). As a result of the left truncation, the estimated Kaplan-Meier survival curves are upwardly biased. The second bias - namely, the immortal-time bias (3,4) - has to do ...

Objective: To report prognostic factors and follow-up data for an unselected group of patients with carcinoma in situ (CIS) of the urinary bladder treated with bacille Calmette-Guérin (BCG). Material and Methods: The clinical records of patients with CIS treated with BCG were reviewed. All 173 patients treated between 1986 and 1997 in four hospitals in two Swedish cities were included. The median follow-up period was 72 months (range 6-154 months). The impact of 18 variables on the times to recurrence and progression was studied using multivariate Cox proportional hazard regression and Kaplan-Meier analyses. Results: No pre-treatment variables, including type of CIS and T1G3 tumour, had prognostic value in terms of time to progression. The result of the first cystoscopy had a very strong prognostic importance: 44% of patients with a positive first cystoscopy progressed in stage, 59% were BCG failures and 35% died from urothelial cancer.

Results: The median overall and progression-free survivals of cohort were 13.3 and 7.8 months, respectively. On multivariate Cox proportional hazard regression analysis, presence of ...
The profiles of patients with fulminant hepatic failure (FHF) from developing countries have not been reported earlier. The current study was conducted prospectively, at a single tertiary care center in India, to document the demographic and clinical characteristics, natural course, and causative profile of patients with FHF as well as to define simple prognostic markers in these patients. Four hundred twenty-three consecutive patients with FHF admitted from January 1987 to June 1993 were included in the study. Each patients serum was tested for various hepatotropic viruses. Univariate Coxs regression for 28 variables, multivariate Coxs proportional hazard regression, stepwise logistic regression, and Kaplan-Meier survival analysis were done to identify independent predictors of outcome at admission. All patients presented with encephalopathy within 4 weeks of onset of symptoms. Hepatotropic viruses were the likely cause in most of these patients. Hepatitis A (HAV), hepatitis B (HBV), ...

Background: Gene expression profiling has made considerable contributions to our understanding of cancer biology and clinical care. This study describes a novel gene expression signature for breast cancer-specific survival that was validated using external datasets. Methods: Gene expression signatures for invasive breast carcinomas (mainly Luminal B subtype) corresponding to 136 patients were analysed using Cox regression and the effect of each gene on disease-specific survival (DSS) was estimated. Iterative Bayesian Model Averaging was applied on multivariable Cox regression models resulting in an 18-marker panel, which was validated using three external validation datasets. The 18 genes were analysed for common pathways and functions using the Ingenuity Pathway Analysis software. This study complied with the REMARK criteria. Results: The 18-gene multivariable model showed a high predictive power for DSS in the training and validation cohort and a clear stratification between high- and low-risk ...

Background The identification of additional prognostic markers to improve risk stratification and to avoid overtreatment is one of the most urgent clinical needs in prostate cancer (PCa). MicroRNAs, being important regulators of gene expression, are promising biomarkers in various cancer entities, though the impact as prognostic predictors in PCa is poorly understood. The aim of this study was to identify specific miRNAs as potential prognostic markers in high-risk PCa and to validate their clinical impact. Methodology and Principal Findings We performed miRNA-microarray analysis in a high-risk PCa study group selected by their clinical outcome (clinical progression free survival (CPFS) vs. clinical failure (CF)). We identified seven candidate miRNAs (let-7a/b/c, miR-515-3p/5p, -181b, -146b, and -361) that showed differential expression between both groups. Further qRT-PCR analysis revealed down-regulation of members of the let-7 family in the majority of a large, well-characterized high-risk ...
