How many months after the close of the diagnosis year should expected cases of reportable cancer be reported?

The correct answer indicates that expected cases of reportable cancer must be reported 23 months after the close of the diagnosis year. This timeline reflects the standards set forth by the Commission on Cancer for reporting purposes. The 23-month period allows for adequate time to collect, validate, and finalize data pertaining to new cancer cases diagnosed in the previous year.

This timeframe is essential because it ensures that cancer registry staff can perform comprehensive quality checks and confirm the accuracy of the data before submission. It provides a buffer for necessary follow-ups on incomplete or pending cases and allows for any necessary corrections based on additional treatments or outcomes that may emerge in those months. By adhering to this timeline, facilities maintain compliance with CoC standards, which ultimately aids in effective cancer surveillance and research efforts.
