Evaluating and improving methods for measuring cancer outcomes is critically important for NCI's initiatives to enhance
the quality of cancer care, reduce cancer-related health disparities, and better understand the burden of disease on individuals
and populations. To assess the current state of the science and to identify priorities for future research and practice, the Applied
Research Program (ARP) created the Cancer Outcomes Measurement Working Group (COMWG) to evaluate existing endpoint measures and
formulate alternative strategies for valid, reliable, sensitive, and feasible clinical and patient-centered endpoint measures.
These measures include health-related quality of life, satisfaction with patient care and health system performance, and the economic
burden of cancer. COMWG focuses on the four major disease sites (breast, prostate, colorectal, and lung) across the entire continuum of care.
Another focus of COMWG is improving outcomes measurement through the use of improved statistical methods for identifying clinical meaningful
differences and accounting for missing data, and through the tools provided by the field of psychometrics. To that effort, the Applied Research
Program has created tutorials and provided references for researchers to learn about psychometric tools and other tools to aid in assessing and
developing outcomes measures. Questionnaire Design and Testing provides more information on psychometric tools. To better understand the impact
of prostate cancer and its treatment on patient outcomes, the Prostate Cancer Outcomes Study
was initiated in 1994 to study practice patterns and
health-related quality of life in a large sample of patients in diverse health care settings.
