CanCORS Research Aims

The CanCORS Consortium had three primary research aims:

  1. assess the quality of care received by cancer patients and survivors;
  2. explore the relationship between quality of care and patient health outcomes; and
  3. evaluate how characteristics of patients, providers, caregivers, and delivery systems affect quality of care and outcomes.

Although many studies have documented disparities in care, few have explored the reasons for these disparities. Few data are available about relationships between quality of care and outcomes among patients who would not meet criteria for enrollment in many clinical trials; these include elderly patients and patients with substantial co-morbidity. For these reasons, it is important to generate scientifically rigorous insights that can improve the care and outcomes among patients with lung cancer and colorectal cancer, the two leading causes of cancer incidence and mortality in the US.

To achieve these aims, CanCORS investigators examined questions including the following:

  • Are there racial, ethnic, and socioeconomic differences in use of effective therapies for colorectal cancer and lung cancer?
  • Are there racial, ethnic, and socioeconomic differences in patients' assessments of the quality of cancer care?
  • How do patients and physicians decide about therapies for colorectal cancer and lung cancer?
  • Why do outcomes of lung cancer surgery and colorectal cancer surgery vary by hospital and surgeon volume?
  • What factors explain participation in clinical trials for lung cancer and colorectal cancer?
  • Are patients' symptoms recognized and treated effectively at different stages of illness?
