This study presents the relationship between Carcinoembryonic Antigen (CEA) levels and median overall survival (OS) in cancer patients during weeks 3 to 5. Logrank tests indicated significant differences in OS based on CEA levels. For CEA < 0.25 ng/mL, the median OS was 24.9 months, while for CEA > 0.25 ng/mL, it was only 12.5 months, highlighting the prognostic value of CEA. Additionally, reductions in CEA levels showed a correlation with improved median OS, emphasizing the importance of monitoring CEA for treatment outcomes.
