New PLCO Data: Biliary cancers, Questionnaires (DHQ, DQX, HSQ), Ancillary Studies and Lab Data
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

The total PLCO population now has 154,898 participants. Over the course of the trial this number decreases due to participants withdrawing, improper consent at randomization or duplication at randomization.
