Conclusion
In conclusion, the results of our study demonstrate that ALDH1 positivity was associated with disease-related survival and RT sensitivity. CD44 positivity did not differ between patients with and without recurrence after RT. In our study, sample size is small and needs to be done larger cohort studies for the powered the predictive effects of these markers. For ALDH1 positivity to be used as a biomarker when making treatment decisions, it is necessary to conduct studies with a larger patient series and determine its correlation with other biomarkers.
