title: Treatment systems guidelines for primary rectal cancer from the 1996 Patterns of Care Study.
abstract: OBJECTIVE
  The Patterns of Care Rectal Cancer Committee was formed to develop consensus recommendations for patients with adenocarcinoma of the rectum limited to the pelvis.
  
  
  METHODS
  The Committee was composed of a multidisciplinary group of oncologists, and clinical scenarios were chosen to address most of the major treatment controversies in the combined modality treatment of rectal cancer. A literature search was then conducted and the major articles were identified. A modified Delphi technique was used to arrive at consensus. Serial surveys were conducted by distributing questionnaires to the Committee members to consolidate expert opinion. Voting was conducted using a scoring system and opinions were unified to the highest degree possible.
  
  
  RESULTS
  Consensus voting was performed for 4 clinical scenarios. Acceptability ratings for treatment were grouped into 3 broad categories: not acceptable, acceptable, and most acceptable. Based on the treatment options, a decision tree was developed that reflects the consensus of the committee.
  
  
  CONCLUSIONS
  These options may help guide treatment decisions in rectal cancer.
