Colorectal

If a participant was diagnosed with colorectal cancer during the trial, medical records of treatment for that cancer are obtained. Records were obtained only for treatments that occurred within one year of the cancer diagnosis, and include resections, chemotherapy, radiation and other procedures.

For most purposes, cancer treatment data can be obtained within the Colorectal dataset. Additional details can be found in the Colorectal Treatments dataset (one record per treatment per person).

Summary Available Data

  • Collected on TIC (Treatment Information - Colorectum) forms:
