Photon-counting computed tomography in esophageal cancer: correlation of iodine concentration with histopathology and treatment response to neoadjuvant radiochemotherapy
To investigate the association between iodine concentration (IC) obtained via photon-counting computed tomography (PCCT) and key histopathological features in esophageal cancer (EC), and to evaluate the role of IC in predicting tumor response to neoadjuvant radiochemotherapy (NARC), highlighting its potential impact on clinical practice.
Key Findings:
Iodine concentration values correlated with tumor characteristics such as grade and lymphovascular invasion.
Normalized iodine concentration (NIC) was predictive of treatment response to NARC.
Higher NIC values were associated with better tumor regression grades.
Interpretation:
The findings suggest that IC measured by PCCT can serve as a valuable biomarker for assessing tumor characteristics and predicting treatment response in esophageal cancer.
Limitations:
Retrospective design may introduce selection bias, potentially affecting the reliability of the findings.
Limited sample size may affect generalizability to broader populations.
Potential variability in imaging techniques and interpretation could influence results.
Conclusion:
PCCT-derived iodine concentration is a promising tool for characterizing esophageal cancer and predicting treatment response to neoadjuvant radiochemotherapy, suggesting a need for further research to validate these findings in larger cohorts.
