Definitive Surgical Procedure, Days from Dx

DD_category: 
PUF Data Item Name: 
DX_DEFSURG_STARTED_DAYS
length: 
4
Allowable values: 
0 – 9999
Description: 
The number of days between the date of diagnosis (NAACCR Item #390) and the date on which the most definitive surgical procedure was performed on the primary site (NAACCR Item #3170).
Registry Coding Instructions: 

None.

Analytic Note: 

The Date of the Most Definitive Surgical Procedure of the Primary Site was added to FORDS in 2003, so this item is not defined prior to that year.  It refers to the last date that first course surgery of the primary site was performed for the patient.  For example, a breast cancer patient may have been treated with an excisional biopsy, followed by a lumpectomy, followed by a mastectomy.  This item identifies the time period between the Date of Initial Diagnosis and the date of the mastectomy.  The Surgical Procedure of the Primary Site will record the mastectomy.
 
CoC cancer programs are required to identify treatment their patients received from all sources.  Surgical treatment may have occurred at any facility, or at multiple facilities, not limited to the one whose report is included in this file.  This refers to the final surgery of the primary site, cumulative for all procedures, for the cancer by any facility.
