About this trial
A pre-metastatic target organ/primary lesion fusion radiomics model was developed based on the "soil-seed" theory to predict comman tumor metastasis in retrospective settings. To prospectively verify the performance of the target organ/primary lesion fusion radiomics model in predicting tumor metastasis patterns (brain metastasis in lung cancer, liver metastasis in colorectal cancer, lung metastasis in breast cancer), we designed this prospective observational trial.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
ECOG performance status score 0-2;
Histologically or cytologically confirmed stage III-IV NSCLC;
If the baseline pathology is adenocarcinoma, driver gene testing (at least EGFR/ALK/ROS1/KRAS/MET) should be performed;
Complete imaging data of baseline stage (contrast-enhanced MR For lung cancer, contrast-enhanced MR/CT for colorectal cancer, and chest CT for breast cancer);
Disqualifiers
Patients with indeterminate pathological type;
Patients without baseline imaging data before treatment;
Baseline imaging examination showed that the corresponding target organ had metastasis (lung cancer/colorectal cancer/breast cancer corresponding to brain/liver/lung metastasis);
patients who cannot or refuse to receive regular imaging follow-up;
Trial population
This study was a prospective observational study. According to the inclusion and exclusion criteria, patients with stage III-IV lung cancer without brain metastasis, colorectal cancer without liver metastasis, and breast cancer without lung metastasis were enrolled. The baseline imaging data and other clinical information were systematically collected, and the enrolled patients were assigned to the high-risk group and the low-risk group according to the radiomics prediction model. The radiomics prediction performance of the previously established metastatic target organ/primary lesion fusion radiomics model for tumor metastasis was regularly followed up and prospectively verified.

Trial outcomes
Primary outcomes
brain metastasis-free survival, BMFS
All patients were followed up regularly for at least 3 years. brain metastasis-free survival (BMFS) between the high-risk group and the low-risk group during follow-up was the primary endpoint. log-rank method was used to calculate the hazard ratio (HR) and 95% confidence interval (CI) of brain metastases between the two groups. If the hazard ratio was less than 0.75 and the upper limit of the 95% confidence interval was less than 1, the study was considered to have met the prespecified end point.
Secondary outcomes
1-year/2-year/3-year BMFS rate
1-year/2-year/3-year brain metastasis-free survival rate
progression free survival
From date of treatment start until the date of progression or the date of death due to any cause, evaluated according to RECIST 1.1 criteria,
overall survival
From date of treatment start to any cause death or last follow-up.
