ABSTRACT:

Background

The number of cancer survivors has steadily increased due to earlier detection and more effective therapies. Do all types of cancer survivors have an increased risk of developing subsequent cancers compared with the general population?

Methods

Patients diagnosed with malignant cancer between January 2000 and December 2021 were included from the SEER 17 Registries (excl AK) database. Events were defined as subsequent cancer at any site according to ICD-O-3/WHO 2008. The observed and expected numbers of subsequent cancers were retrieved, and observed/expected (O/E) ratios and excess risks were calculated to assess the risk of developing subsequent cancers in cancer survivors compared with the United States general population within the same period.
