A Pan-cancer Screening and Diagnosis Model Based on Abdominal CT Was Established
Zhejiang Cancer Hospital · NCT06614179
This study is testing a new way to use CT scans to help find and diagnose abdominal tumors in patients who have them and those who don’t.

What this trial studies
This observational study aims to establish a screening and diagnostic model for abdominal tumors utilizing both non-contrast and contrast-enhanced abdominal CT scans. The study will include patients with pathologically diagnosed abdominal tumors and a non-tumor population to validate the model's accuracy. The secondary objective is to develop a grading model based on clinical indicators, enhancing the understanding and detection of abdominal neoplasms. The study will also ensure comprehensive follow-up data is collected for all participants.
Who should consider this trial
Good fit: Ideal candidates include patients with pathologically confirmed abdominal tumors and those from a non-tumor population with complete clinical data.
Not a fit: Patients with unclear lesions on CT images or those with active abdominal bleeding or serious infections may not benefit from this study.
Why it matters
Potential benefit: If successful, this model could significantly improve early detection and diagnosis of abdominal tumors, leading to better patient outcomes.
How similar studies have performed: While similar approaches have been explored, this specific model for abdominal tumors using CT scans is novel and untested.
Eligibility criteria
Show full inclusion / exclusion criteria
Inclusion Criteria: * Patients with abdominal tumors: * all patients were pathologically diagnosed with abdominal tumors; * The clinical case data of all patients were complete, and complete follow-up was obtained, with clear information on medical visits, operation time and survival status within 2 years. If the cause of death is unknown, it will be recorded as censored data; * All patients had no history of active abdominal bleeding, no serious infection or other abdominal diseases that affected the observation of CT imaging within 3 months before surgery. * Non-tumor population: * all patients have complete clinical case data, complete abdominal CT, no history of malignant tumors, no serious infections or other abdominal diseases that affect the diagnosis and observation of CT imaging. Exclusion Criteria: * Cases in which contrast-enhanced or noncontrast CT images show unclear lesions, with significant noise and artifacts;
