Comparison of Duke Activity Status Index with cardiopulmonary exercise testing in cancer patients

ConclusionIn summary, both the limits of agreement and bias between the measured and DASI-predicted pVO2 were substantial. The DASI-predicted pVO2 based on patient ’s assessment of their functional status could not be considered a reliable surrogate of measured pVO2 during CPET for the population of patients pending major cancer surgery and cannot, therefore, be used as a triage tool for referral to CPET centres for objective risk assessment.
