Study population: The Surveillance, Epidemiology, and End Results (SEER) database is a comprehensive source of population - based cancer incidence and survival data in the United States. The population covered by the SEER database is diverse and representative of the broader U.S. population. It includes individuals from various racial and ethnic backgrounds, age groups, and geographic regions. The data are collected from 17 population - based cancer registries, which cover approximately 28% of the U.S. population. This allows for the analysis of cancer - related outcomes and trends across different demographic and socioeconomic groups, providing valuable insights into the burden of cancer and the effectiveness of cancer - related interventions in a population - based setting.
Who may be able to join
- Patients diagnosed with Gastric - type Endocervical Adenocarcinoma were identified using the SEER database and SEER*Stat 8.4.2 software. The search scope was the "SEER Research Plus Data, 17 Registries, Nov 2021 sub (2000 - 2019)" database. The screening criteria included "Site and Morphology, Analytic Behavior Recode = Malignant" and "Site and Morphology, ICD - O - 3 / WHO 2008 Recode Site = Cervix". Patients with Gastric - type Endocervical Adenocarcinoma in the database were selected.
Who cannot join
- Patients with a survival time of 0 or unknown.
