- Number of tumors at diagnosis Cancer
- Number of tumors at diagnosis
- This data item is used to count the number of individual reportable tumors (multiplicity) that are present at the time of diagnosis or the number of reportable tumors that occur within one year of the original diagnosis reported as a single primary using the SEER, IARC, or Canadian Cancer Registry multiple primary rules. Patients with multiple tumors 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 reportable 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 also 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
