ClinicalDate of diagnosis of multiple tumors Cancer
Definition
This data item is used to identify the month, day and year the patient is diagnosed with multiple or subsequent reportable tumor(s) reported as a single primary using the SEER, IARC, or Canadian Cancer Registry multiple primary rules. Multiple tumors must have the same histology as the original tumor and must be located in the same organ or primary site as the original tumor, using primary site and histology coding rules. See page 81 for date format. Record the Date of Diagnosis as the Date of Multiple Tumors when multiple reportable tumors are abstracted and reported as a single primary at the time of initial diagnosis. Record the date the first subsequent reportable tumor was diagnosed (same histology and same site as the original tumor, using the primary site and histology coding rules). The Date of Multiple Tumors must occur within one year following the initial/first diagnosis of the reported tumor. 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. The Date of Multiple Tumors will allow separation of cases with multiple reportable tumors present at the time of initial diagnosis from cases with subsequent reportable tumors. The date will allow tracking of the time interval between the date of original diagnosis and the first date of subsequent tumor(s) for specific primary sites and tumor histologies. ..
