Abstract
To assess the association between psychological status and prognosis of patients with digestive system cancer, epidemiological investigations were conducted in 2 periods to obtain information about the patients' psychological status, survival time, and quality of life. Adjusted relative risks (95% confidence interval) of 1-year survival rate for anxiety and depression were 8.43 (1.18-60.20) and 9.62 (1.76-52.63), respectively. Relations between quality of life and depression and social support were statistically significant (P <.05). This study offers evidences that psychological status in a short-term postoperative period may affect 1-year survival rate, and poor psychological status and social support after being discharged from hospitals are associated with poor quality of life.
