Quality of Life of Patients after Colorectal Cancer Surgery as Assessed Using EQ-5D-5L Scores

This study aimed to evaluate the health-related quality of life(QOL)using EQ-5D-5L scores for patients who underwent surgery for colorectal cancer. A total of 30 consecutive patients(14 men and 16 women; median age: 67.5 years)from the outpatient clinic of our institute in January 2017 were eligible for this study. The primary tumor was located in the colon(n= 18)or rectum/anu(s n=12). Twelve patient(s 40.0%)had cancer recurrence, and 3 patient(s 10.0%)had a stoma. In addition, 11 patients(36.7%)underwent chemotherapy. The median EQ-5D-5L score for all the patients was 0.867(range, 0.324- 1.000). The EQ-5D-5L score of patients with recurrence was significantly lower(0.820)than that of patients without recurrence( 0.948)(p=0.002). Furthermore, the EQ-5D-5L score of women(0.834)was significantly lower than that of men (0.942)(p=0.015). No significant difference was noted between the EQ-5D-5L score and other factors, such as age, cancer stage, location of primary tumor, absence/presence of chemotherapy, and absence/presence of stoma. In conclusion, using EQ-5D-5L scores, female gender and cancer recurrence were found to be associated with low QOL of patients after surgery for colorectal cancer.
