Accurate estimates of cancer survival are important for assessing optimal patient care and prognosis. Evaluation these via relative (a ratio observed expected rates) requires a population life table that is matched to the by age, sex, race and/or ethnicity, socioeconomic status, ideally risk factors under examination. Because tables all subgroups in study may be unavailable, we investigated whether cause-specific could used as an alternative survival.We data from Surveillance, Epidemiology,...

Selected molecular biomarkers were incorporated into the US cancer registry reporting for patients with brain tumors beginning in 2018. We investigated completeness and validity of these variables described epidemiology molecularly defined tumor types.

The incidence of gastrointestinal stromal tumors (GISTs) increased after the implementation GIST-specific histology coding in 2001, but updated data on trends and survival are lacking.

There are over 100 histologically distinct types of primary malignant and nonmalignant brain other central nervous system (CNS) tumors. Our study presents recent trends in the incidence these tumors using an updated histology recode that incorporates major diagnostic categories listed 2016 World Health Organization Classification Tumours CNS.We used data from SEER-21 registries for patients all ages diagnosed 2000-2017. We calculated age-adjusted rates fitted a joinpoint regression to...

Abstract Background: Stage is the most important prognostic factor for understanding cancer survival trends. Summary stage (SS) classifies based on extent of spread: In situ, Localized, Regional, or Distant. Continual updating staging systems poses challenges to comparisons over time. We use a consistent summary classification and present trends 25 sites using joinpoint (JPSurv) model. Methods: developed modified variable, Long-Term Site-Specific Stage, as definition possible applied it...

Although incidence rates of hepatocellular carcinoma (HCC) began to decline in the United States past decade, disparities among racial/ethnic groups have persisted. Whether stage at diagnosis remained over time, however, is unclear.National Cancer Institute's Surveillance, Epidemiology and End Results (SEER) program has created a new staging-over-time variable that facilitates examination trends HCC stage. Thus, proportions HCCs diagnosed by between 1992 2019 were examined non-Hispanic...
