چکیده مقاله:
Introduction: Although radiation is recognized as the most effective nonsurgical treatment, the outcomes and control rates are generally poor. However, a combination of radiation therapy with hyperthermia and chemotherapy can improve the efficacy of treatment. The aim was to explore the potential of morphological and gradient-based features on microscopic images in improving the identification accuracy of subtle differences in cell structure during different treatments. Materials and Methods: Fifty single-cell images were used for each group and treatment regimen. The groups were individually subjected to: ۱) hyperthermia at ۴۳°C; ۲) temozolomide (TMZ) chemotherapy at ۱۰% inhibitory concentration; ۳) radiotherapy at ۲Gy; ۴) combination of TMZ chemotherapy and hyperthermia; ۵) combination of radiotherapy and hyperthermia; ۶) combination of TMZ chemotherapy and radiotherapy; and ۷) combination of TMZ chemotherapy, radiotherapy, and hyperthermia. Morphological and gradient-based features were extracted from each cell. The area under the receiver operating characteristic curve (AUC) was calculated for each significant feature to evaluate the performance of cell change detection. Results: According to AUCs, gradient-based features showed superior performance to morphological features in identifying cell changes during all treatment regimens in all groups. In this regard, the AUC of the gradient-mean feature exceeded ۰.۵۹۹ for all groups. The ratio of maximum to minimum cell diameter was the best morphological feature, with an AUC above ۰.۵۸۸ for all groups. Conclusions: Quantitative analysis of features is a reliable indicator of damage, with the potential to characterize cell changes during treatment regimens.
