Study on Adaptive Radiotherapy and Multimodal Information of Cervical Cancer Assisted by Artificial Intelligence

Summary

The standard treatment for non-operative cervical cancer is concurrent external radiation therapy and chemotherapy followed by brachytherapy. During the period of radiotherapy, organ movement and tumor shrinkage may lead to insufficient or excessive radiation dose for the tumor and organs at risk. Adaptive radiotherapy can use images information acquired during treatment as feedback to reduce errors.

Total 122 cases of cervical cancer with stage IB2-IVA will be randomly enrolled. Concurrent external volumetric rotational intensity modulated radiotherapy and chemotherapy followed by image-guided adaptive brachytherapy is the treatment strategies of control group patients.

Concurrent adaptive external volumetric rotational intensity modulated radiotherapy and chemotherapy followed by image-guided adaptive brachytherapy is the treatment strategies of experimental group patients. CT repositioning will be performed after 15fractions of external radiotherapy, then new target volume will be contoured and new radiotherapy plan will be formulated with the assistance of artificial intelligence program. New radiotherapy plan will be performed from the 17th fraction external radiotherapy. Information on side effects, survival, dosimetry, imaging, clinical features, and cost-effectiveness will be collected. The statistical analysis is as follows, First is the difference in grade 3 side effects between the two groups. Second is 2-year PFS and OS differences between the two groups. Third is relationship between dosimetric differences and prognosis. Fourth one is to analyze the prognostic and predictive factors of adaptive radiotherapy from the patient's clinical characteristics, Positron emission tomography-computed tomography(PET/CT), Magnetic Resonance Imaging(MRI) and other multimodal information. Fifth is cost-benefit analysis of Artificial Intelligence(AI).
