Long-Term Survival in Patients with Cancers: Surveillance, epidemiology and end results-based analysis.

Objectives: This study aimed to explore real-world data on the long-term survival of cancer patients using historical records from the Surveillance, Epidemiology, and End Results (SEER) Programme. Long-term survival is an important endpoint in the management of different malignancies. It is rarely assessed due to the unfeasibility of follow-up for a long duration of time.
