Research on Improving Radiotherapy Accuracy Based on Image-Guided Radiotherapy.

Area of Science:

• Oncology
• Medical Imaging
• Radiation Therapy

Background:

• Increasing incidence of abdominal malignant tumors due to lifestyle changes.
• Need for enhanced accuracy in radiotherapy for abdominal cancers.
• Limitations of conventional imaging in precise tumor targeting.

Purpose of the Study:

• To evaluate the effectiveness of cone-beam CT (CBCT) enhancement in improving radiotherapy accuracy for abdominal malignant tumors.
• To assess the impact of CBCT-guided radiotherapy on patient outcomes.
• To analyze the influence on immune function and complication rates.

Main Methods:

• A study involving 92 patients with abdominal malignant tumors.
• Patients were divided into a control group and a CBCT radiotherapy group.
• Comparison of treatment outcomes, immune function markers, and complication incidence between groups.

Main Results:

• CBCT enhancement technology significantly improved radiotherapy accuracy.
• Patients receiving CBCT-guided radiotherapy showed enhanced immune function recovery.
• Improved overall treatment effectiveness was observed in the CBCT group.
• A notable decrease in the incidence of treatment-related complications.

Conclusions:

• Cone-beam CT enhancement is effective in improving radiotherapy accuracy for abdominal malignant tumors.
• Precise radiotherapy guided by CBCT positively impacts patient immune function and treatment outcomes.
• CBCT-guided radiotherapy offers a promising approach to reduce complications in cancer treatment.
