Estimating and modelling relative survival
Relative survival, the survival analogue of excess mortality, is the method of choice for estimating patient survival using data collected by populationbased cancer registries. The relative survival ratio is typically estimated from life tables as the ratio of the observed survival of the patients (where all deaths are considered events) to the expected survival of a comparable group from the g...
متن کاملEstimating the Net Survival of Patients with Gastric Cancer in Iran in a Relative Survival Framework
Background: Iran is an Eastern Mediterranean region country with the highest rate of gastric cancer. The present study aimed to evaluate the 5-year net survival of patients with gastric cancer in Iran using a relative survival framework.Methods: In a cross-sectional study, using life-table estimation of relative survival, we reported 1- to 5-year relative survival regarding age, sex, disease st...

متن کاملOn standardized relative survival
Cancer survival comparisons between cohorts are often assessed by estimates of relative or net survival. These measure the difference in mortality between those diagnosed with the disease and the general population. For such comparisons methods are needed to standardize cohort structure (including age at diagnosis) and all-cause mortality rates in the general population. Standardized non-parame...
متن کاملEstimating haplotype relative risks on human survival in population-based association studies.
Association-based linkage disequilibrium (LD) mapping is an increasingly important tool for localizing genes that show potential influence on human aging and longevity. As haplotypes contain more LD information than single markers, a haplotype-based LD approach can have increased power in detecting associations as well as increased robustness in statistical testing. In this paper, we develop a ...
