Description:
A system-generated number that, together with Patient ID Number [20], can be used to uniquely identify a tumor over time. Tumor Record Number is assigned to each of a patient’s tumors sequentially in the order in which the tumor record is created by the central registry. A patient’s first tumor record is assigned Tumor Record Number 01. Tumor Record Number is assigned to each of a patient’s tumors sequentially in the order in which the tumor record is created by the central registry and may not match timing based on Diagnosis Date.
For example, the first tumor created in the database is diagnosed 12/2022 and is assigned Tumor Record Number = 01; the registry later learns the patient had a separate tumor diagnosed 5/2020, this is the second tumor created in the database and assigned Tumor Record Number = 02.
If a tumor is deleted or replaced, the Tumor Record Number associated with the deleted case is not reused.
For example, Patient has three cancers, Tumor Record Numbers = 01, 02 and 03. Upon review, it is determined that the cancer assigned Tumor Record Number 02 is actually a recurrence of 01 and it is deleted.
Patient now has two cancers, Tumor Record Numbers = 01 and 03. If a new tumor is created for this patient, 02 will never be reused and Tumor Record Number will be assigned as 04.
Unlike Sequence Number, behavior code has no effect on how Tumor Record Number is assigned.
Rationale:
It is important to be able to track a specific de-identified tumor over time for linkage purposes. Sequence Number—Central [380] and Sequence Number—Hospital [560] can change as more information becomes available about a case (i.e., diagnosis of a second primary changes sequence number 00 to 01, or discovery of a prior diagnosis may change sequence number 02 to 03). Sequence numbers are also reused if a tumor is deleted. Therefore, sequence number cannot be used to uniquely link a specific tumor. Tumor Record Number, together with Patient ID Number, provide the continuity to uniquely identify a specific tumor over time.
