Advanced GEP-NET Survival Trends from SEER Data, 2004-2022

Omar Abdel-Rahman's dataset analyzes changes in overall and cancer-specific survival for patients with advanced gastroenteropancreatic neuroendocrine tumors (GEP-NETs). The data, sourced from the Surveillance, Epidemiology and End Results (SEER) database, compares outcomes between patients diagnosed from 2004-2013 and those diagnosed from 2014-2022. It was last updated on April 15, 2026.

Use Cases

• Modeling survival probability over time based on Kaplan-Meier estimates described in the study.
• Analyzing factors associated with survival outcomes using multivariable Cox regression methods mentioned.
• Comparing cancer-specific survival (CSS) between different diagnostic periods (2004-2013 vs. 2014-2022).
• Investigating differences in survival based on primary tumor location (gastrointestinal tract vs. pancreas).

Strengths

• Data is sourced from the authoritative SEER (Surveillance, Epidemiology and End Results) database.
• Analysis covers a substantial 18-year time range (2004-2022).
• Results include specific statistical measures, such as hazard ratios (HR: 1.149) and median survival times (67 vs. 70 months).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (288.2 KB), indicating limited scope, likely containing summary statistics rather than raw patient records.
