LOINC description : This data item is used to identify cases with multiple tumors that are abstracted
and reported as a single primary using the SEER, IARC, or Canadian Cancer Registry
multiple primary rules. Multiple tumors may individually exhibit in situ, invasive,
or any combination of in situ and invasive behaviors. Multiple intracranial and central
nervous system tumors may individually exhibit benign, borderline, malignant, or any
combination of these behaviors. Multiple tumors found in the same organ or in a single
primary site may occur at the time of initial diagnosis or within one year of the
initial diagnosis. The data item does not apply to metastatic tumors. Data will be
collected at the time of initial case abstract or within one year of the initial diagnosis.
This data item is also used when a physician states that there are two or more primaries,
but for surveillance purposes, the case is reported as a single primary. Patients
with multiple tumors that are currently reported as a single primary for surveillance
purposes may have a worse prognosis or more extensive treatment than patients with
a single tumor. This data item will make it possible to identify important information
about these cases for data analysis. Data collected under this item will be used to
assess the number, type, and anatomic location of multiple tumors currently abstracted
as a single primary using the SEER, IARC, or Canadian Cancer Registry rules for determining
multiple primary cancers and the impact of these cases on cancer case counts and incidence
rates. Data will also serve as a basis for measuring the impact and feasibility of
future modifications to the multiple primary rules. This data item will make it possible
to compare individually reported cancer cases with historical data if the rules are
changed. .. NAACCR Data Standards and Data Dictionary Version 11;
