07/30/10 - Revised Specifications for Converting CSv1 to CSv2 Released
Specifications for converting from version 1 to version 2 of Collaborative Stage have been revised to accommodate Site-Specific Factors 1 through 6 for which blank was an acceptable value but which are now required to derive staging information.
After the first release of the conversion specifications, a problem was discovered that resulted in cases failing to derive either TNM, 6th ed., or Summary Stage 77 and Summary Stage 2000, although the cases had derived all stage information in version 1. The problem occurred when site-specific factors which were either not defined or not required in the past became required for staging in version 2, and only when the newly required site-specific factor had been left blank. The specifications have been revised to rectify this problem, which only affected five of over 150 schemas. There are changes in both components of the specifications, the Word document and the Excel spreadsheet.
The revisions to the conversion of Collaborative Stage will be incorporated into the next release of CDC’s general program for converting cancer registry records from the NAACCR 11 layout to the NAACCR 12 layout. The new version of the CDC program, released as NCONV12.DLL, will be version 1.0.2.
Users who have not already converted from NAACCR 11 to NAACCR 12 should use the new specifications and the new version of NCONV12.DLL, version 1.0.2, which will also include a change to the conversion of Class of Case described in a revised implementation document published by NAACCR. Users who have already converted can use the revised specifications to program corrections to any CS data they may have with the problem.
Modification of the CS Testis Schema - updated July 9, 2010
Since the publication of the AJCC 7th edition, important information related to the capture of serum tumor markers has been brought forward to the AJCC chapter authors. Read More
Schema ID Names/Sites/Histology Groups- updated July 8, 2010 - This listing identifies the AJCC 6th and 7th Edition chapters and the corresponding CSv2 schema. It also includes ICD-O-3 primary site codes and histology codes. The last column indicates the primary site and histology codes that generate stage.
Program to Convert from Collaborative Stage Version 1 to Version 2
CDC has released Northcon12, a freestanding Windows-based utility program that converts a file of cancer registry records in NAACCR11 record layout format to the NAACCR 12 record layout. Conversion of Collaborative Stage (CS) data from version 1 to version 2 is embedded in this program. The CS conversion is based on the published specifications and has been extensively tested. When the conversion is run, the user has the option to derive the Collaborative Stage version 2 stage outputs on appropriate records. For more information or to download the program, see the CDC-NPCR Web page at:
Instructions for accessing the program’s underlying dynamic link libraries (DLLs) are also available on this Web page. These can be used by anyone who wishes to perform the conversions using another program.
