PurposeThe purpose of present study was to calculate utility values in colorectal cancer (CRC) patients by EQ-5D-5L and cTTO.
MethodsThe EQ-5D-5L and cTTO were used to calculate utility values in the patients. A total of 105 patients with CRC were consecutively selected from chemotherapy ward of the Oncology Center of Omid in the second most population province, Isfahan, in Iran. The difference between mean utility values in each factor examined by the t-test and ANOWA. Finally, The BetaMix was used to identify predictors of the utility.
ResultsThe mean EQ-5D-5L index and cTTO values were 0.45 ±0.03 and 0.51±0.02, respectively. The anxiety and pain were the most common problems reported by the patients. Univariate analyses showed that the difference between the mean EQ-5D-5L index values were signi cant for age, education status, income level, stage of cancer, and comorbidity number; also, showed that the difference between the mean cTTO values were signi cant for age, income level, employment status, stage of cancer, and comorbidity number. The BetaMix showed that lower mean utility values were signi cantly associated with female, aging, a low level of income, a greater number of comorbidities and advanced stage of cancer.
ConclusionThe factors of female, aging, a low level of income, advanced stage of cancer, and a greater number of comorbidities should be considered for improving values of utility. In addition, focusing on anxiety/depression through nancial and social supports can be critical for the improvement in the quality of life in the patients.
