Survival Analysis in Colon Cancer Patients

Abstract

Introduction: The aim of this study is to investigate the degree of risk and significance of prognostic and demographic factors affecting the survival of patients diagnosed with colon cancer (CC). Material and Method: This was a retrospective study conducted by reviweing the medical records of 80 patients diagnosed with metastatic CC at the Oncology Clinic at the Mustafa Kemal University between 01/2018 – 01/2021. Cox regression analysis was performed to determine the prognostic and demographic factors affecting the CC and Kaplan-Meier method was used to estimate the overall survival (OS). Difference between the variable levels in terms of survival probabilities was investigated using the log-rank test. Results: The average age of the patients was 56.72 ± 12.42. The median survival time of patients with colon cancer was 48.42 months (95% confidence interval (CI) = 41.97-54.87). Cox regression analysis showed that age, incident type 2 diabetes mellitus (DB), and family history of CC were significantly associated with OS (p lt;0.005). Patients with CC aged 50 years; patients with DB and patients with a family history of CC were approximately 3 times more at risk compared to patients lt;50 years; patients without DB and patients without CC in the family, consecutively. Discussion and Conclusion: The effect of prognostic and demographic factors affecting the survival of patients with CC was evaluated. Our findings showed that age, DB and family history of CC can be used to estimate the survial of patients with CC. We believe that our results will help guide practitioners for the treatment of patients diagnosed with metastatic CC.
