5. Conclusions
digestive tract cancers, CRC
Overall, our findings underscore the importance of serum sCD40L levels as a prognostic marker in CRC, and suggest that vitamin D supplementation might hold promise in improving outcomes in CRC patients with elevated sCD40L levels. However, it is essential to acknowledge the limitations of our study, including its exploratory nature, sample size constraints, and the specific population under investigation. Further research with larger cohorts and diverse populations is warranted to validate and expand upon these findings, potentially paving the way for personalized treatment strategies in digestive tract cancers.
