Abstract
Background: This study was conducted to determine a hypothetical model for the factors affecting the quality of life of postoperative colorectal cancer patients. Methods: We collected data from 209 patients that was analyzed using SPSS 22.0 and AMOS 25. Results: Predictive variables of the hypothesis model included an exogenous variable, social support, as well as endogenous variables self-efficacy, symptoms, health promotion behavior, and quality of life. Testing of the correction model showed that significant paths directly affecting quality of life of patients after colorectal cancer surgery included health promotion behavior, symptoms, and self-efficacy and also showed an explanation power of 58.7%. Social support was found to have a significant impact on the quality of life indirectly through self-efficiency. Conclusions: To improve the quality of life of colorectal cancer patients, it is necessary to develop a nursing intervention program that strengthens patients’ health promotion behaviors to alleviate their symptoms and improve their social support and self-efficacy.
Highlights
Colorectal cancer is the second most common cancer among men and women in Korea as lifestyles become more westernized, and the incidence rate is increasing every year. the 5-year survival rate increased to 71.8% [1]
To develop a structural model for the quality of life of patients undergoing colorectal cancer surgery, a hypothesis model was constructed based on the quality of life model of Wilson and Cleary [4] and a literature review, and a modified model was presented after validating the significance
The subject’s social support and symptom experience were set as exogenous variables, and the subject’s self-efficacy, symptom experience, health promotion behavior, and quality of life were set as endogenous variables to verify the fit of the model and the significance of direct and indirect pathways
Summary
Colorectal cancer is the second most common cancer among men and women in Korea as lifestyles become more westernized, and the incidence rate is increasing every year. The 5-year survival rate increased to 71.8% [1]. The principle of treatment for colorectal cancer is to achieve a histologically disease-free state through radical resection, and after surgery, adjuvant treatment with chemotherapy is used for high-risk stage 2 or higher depending on the histological stage. In the case of rectal cancer, chemotherapy and radiotherapy are administered before or after surgery as adjuvant treatment to reduce recurrence in the pelvis [2]. In addition to increasing the survival rate of cancer patients, the final treatment goal for colorectal cancer patients is to improve the quality of life of the subjects [2]
