Summary
Intratumoral heterogeneity in cervical cancer impacts treatment. Theranostic imaging and dose mapping improve treatment planning and predict patient response, outperforming conventional methods.
Area of Science:
- Nuclear medicine
- Radiotherapy
- Oncology
Background:
- Intratumoral heterogeneity in cervical carcinoma affects treatment outcomes.
- Conventional uniform planning inadequately addresses this heterogeneity.
- Theranostic imaging offers a potential solution.
Purpose of the Study:
- To investigate the link between intratumoral heterogeneity, dosimetry, and treatment response in cervical cancer.
- To compare conventional planning with theranostic-guided spatial optimization.
- To develop an integrated theranostic score for response prediction.
Main Methods:
- 35 cervical cancer patients underwent baseline theranostic imaging.
- Voxel-wise tumor uptake analysis and dose estimation.
- Comparison of conventional uniform planning with theranostic-guided optimization.
Main Results:
- Nonresponders exhibited higher uptake intensity and heterogeneity.
- Theranostic-guided optimization improved target coverage and conformity.
- Integrated theranostic score showed strong predictive performance (AUC 0.95).
Conclusions:
- Radionuclide theranostic mapping quantitatively links heterogeneity to dosimetry and response.
- Theranostic-guided planning offers benefits over conventional methods.
- An integrated theranostic score aids response prediction and risk stratification.
