Study of Predicting Lymph Node Metastasis of High-risk Prostate Cancer by Artificial Intelligence Multi-omics Analysis

Prior treatment

• Patients with contraindications to MRI examination, such as metal implants in the body, claustrophobia, etc.

Other illness

• Patients with a clear history of neurological and psychiatric disorders, such as dementia, epilepsy, or seizures

Lab values

• In the judgment of the investigator, there are serious concomitant diseases that endanger the safety of the subjects or affect the subjects' completion of this study (such as severe diabetes, thyroid disease, and mental illness, etc.), or factors that affect the safety of the patients or affect the patients' provision of informed consent (including laboratory abnormalities), or any psychological, family, sociological or geographical conditions that affect the study plan and follow-up plan

Other

• Patients with any missing baseline clinical and pathological information
• The investigator believes that it is not suitable to participate in this clinical trial for any reason
• Unable to provide informed consent
