| description | Code indicates the sequence of all malignant and non-malignant neoplasms over the lifetime of the patient. This item differs from the Sequence Number--Central [380] because the definitions of reportable neoplasms often vary between a hospital and a central registry. Each neoplasm is assigned a different number. Sequence Number 00 indicates that the person has only one malignant neoplasm in his lifetime (regardless of hospital registry reference date). Sequence Number 01 indicates the first of two or more malignant neoplasms, while 02 indicates the second of two or more malignant neoplasms, and so on. Because the time period of Sequence Number is a person's lifetime, reportable neoplasms not included in the hospital registry are also allotted a sequence number. For example, a registry may contain a single record for a patient with a sequence number of 02 because the first reportable neoplasm occurred before the hospital registry's reference date. Similarly, Sequence Number 60 indicates the patient has only one non-malignant neoplasm, and Sequence Number 61 represents the first of multiple non-malignant neoplasms. Reporting Requirements: COC, State/Province, and The Hospital Cancer Committee The COC standard defining which neoplasms are reportable is described in Chapter III, Standards For Case Inclusion and Reportability; it is assumed that this standard is the "minimum" definition of reportability. In addition to the COC-required reportable neoplasms, hospital cancer registries have to meet the reporting requirements of the central cancer registry and the hospital cancer committee. These neoplasms often are called "reportable by agreement" in COC publications. Any tumor in the patient's past that is reportable or reportable-by-agreement must be taken into account when sequencing subsequently accessioned tumors. Sequence numbers should be reassigned if the facility subsequently learns of an unaccessioned tumor that affects sequencing. Sequence Number-Central [380] does not affect Sequence Number-Hospital. The two notational systems are independent. Timing Rule If two or more malignant tumors are diagnosed at the same time, the lowest sequence number will be assigned to the diagnosis with the worst prognosis. Likewise, if two or more non-malignant tumors are diagnosed at the same time, the lowest sequence number is assigned to the diagnosis with the worse prognosis. If no difference in prognosis is evident, the decision is arbitrary... NAACCR Data Standards and Data Dictionary Version 11 | ||||
