Colorectal cancer survival in Thailand

Abstract

Background: Colorectal cancers are third among the world's most common cancers. Among the top five most common malignancies in Thailand, colorectal cancer primarily affects the elderly but affects persons of all ages as well. In addition, its incidence is rising yearly. Objectives: This retrospective cohort study aimed to describe the survival rate of Colorectal cancer patients in Thailand. Methods: The study used secondary data from the Ministry of Public Health between 2013 and 2020, a total of 57,321 cases were enrolled. Descriptive statistical analysis and inferential statistical analysis were performed by Cox regression analysis to observe survival rate estimate, Kaplan-Meier Survival estimate with 95% CI. Results: Among the total participants, 51.28% were male. Female survival rate was 9% higher than male Colorectal cancer patients (HR = 0.91, 95% CI: 0.86-0.94). The Colorectal cancer patients who were aged 61-70 years were more likely to pass away than patients aged £ 60 years (HR= 1.25, 95% CI:1.17- 1.34). Similarly, Colorectal cancer patients aged ≥70 years were more likely to have demise 1.58 times earlier than patients aged £ 60 years (HR= 1.58, 95% CI: 1.49-1.68). Conclusion: The survival rate of patients with colorectal cancer was significantly affected by gender. In addition, age was one of the variables which is also statistically significant that impacted on the colorectal cancer patient survival rate. Therefore, the formulation of screening policies for colorectal cancer in targeted populations, particularly in elderly should be established to support colorectal cancer prevention and reduce the risk to achieve a greater health impact among them.
