New PLCO cancer data added. Data version: may13.d051713
- Biliary Cancer was identified as a cancer of interest. A new dataset is included for biliary cancer. The biliary dataset has the same structure as the existing cancer of interest datasets with the addition of variables bili_type and bili_type2nd, describing the specific nature of the biliary cancer.
- Added to all cancer datasets:
- dcf_unddeath_ccode - What is Cause of Death Cancer Code from Death Certificate?
- f_unddeath_ccode - What is Final Underlying Cause of Death Cancer Code? These provide the 3 digit cancer code to describe cancers for which an ICD code has not yet been determined (e.g. reported cancers not yet confirmed).
- Added to UPGI (upper GI) dataset (differentiates between stomach and esophagus):
- dcf_dthupgi - Is UPGI Cancer The Underlying Cause Of Death (From The Death Certificate)?
- f_dthupgi - Is UPGI Cancer The Underlying Cause Of Death?
- Added to the endoscopy dataset (advanced):
- de_prompt - Was the DEC prompted by a positive screen or by a cancer diagnosis?
- screen_fsg - Was the Endoscopy a Screening FSG?
- Larynx was added to the definition of head-and-neck cancer.
- Colon tumor location variables were renamed :
- colo_tumrloc_side becomes colon_location_side
- colo_tumrloc_summary becomes colon_location_summary
- Colon tumor location variables no longer tablulate insitu colon cancers
