Summary

To fill in the "Brief Summary" field, you need to provide clear, easy-to-understand information about the study for patients, families, and healthcare providers. Here's a suggested summary: This study compares the dosimetric features and clinical effects of body gamma knife and VMAT radiotherapy for locally advanced primary liver cancer. We retrospectively analyze 20 patients from Chifeng Tumor Hospital who cannot or refuse surgery. For each patient, we will develop both body gamma knife and VMAT radiotherapy plans. Then, we'll compare the dose distribution in the tumor target (including conformity index and homogeneity index) and the radiation exposure to organs at risk (such as the spinal cord, stomach, and liver). The goal is to find out which radiotherapy approach is more beneficial, so patients, families, and healthcare teams can better understand how this research supports treatment decisions.
