What this Trial Is About

Bladder cancer is the most common malignant tumor in the urinary system, and determining whether it has invaded the muscle layer is important for choosing the right treatment. This research focuses on using advanced artificial intelligence methods, including deep learning and transfer learning, to improve the accuracy of bladder cancer staging before surgery and to predict how well patients might respond to new chemotherapy treatments. The goal is to reduce overtreatment and help doctors make better decisions based on a multi-omics diagnostic model combining imaging and pathology data. The study involves collecting ultrasound images, magnetic resonance images, pathology slides, and clinical data from patients diagnosed with bladder cancer. These data will be processed using AI algorithms to build models that can accurately identify muscle invasion and predict prognosis. Participants will be grouped into training, internal validation, and external validation sets to develop and test these AI systems. The project also includes creating immune cell maps from ultrasound images and pathology to explore tumor microenvironment features. Participants will undergo contrast-enhanced ultrasound within two weeks before surgery and have follow-up visits at three months postoperatively. Researchers will collect baseline clinical information and imaging data for AI analysis, with tissue samples stained for immune cell study. The study's main measure is the detection of muscle invasion through ultrasound imaging, and outcomes include evaluating the AI system's diagnostic performance. The research aims to provide a helpful tool for clinical treatment decisions and improve diagnostic efficiency in bladder cancer care.

Eligibility Criteria

Eligible

You may qualify if you...

  • Imaging tests such as ultrasound, CT, or MRI suggest bladder masses suspicious for bladder cancer
  • Bladder is well filled with no allergic reactions to ultrasound contrast agents
  • No prior surgery, chemotherapy, or radiation therapy for bladder cancer
  • Planned for surgical treatment due to clinical symptoms like visible blood in urine, confirmed bladder cancer by cystoscopic biopsy, or urine cytology suggesting malignancy
Not Eligible

You will not qualify if you...

  • Unable to tolerate surgery
  • Allergy to ultrasound contrast agents preventing contrast examination
  • Unsuccessful or non-compliant ultrasound contrast examinations before surgery
  • Postoperative pathology does not confirm bladder cancer
  • Previous chemotherapy or radiation therapy for bladder cancer

Your Study Journey

Screening

Duration - 2 to 4 weeks

Participants are screened for eligibility to participate in the trial.

1 visit (in-person)

Diagnostic Evaluation

Duration - Within 2 weeks before surgery

Participants undergo imaging tests including ultrasound, contrast-enhanced ultrasound (CEUS), magnetic resonance imaging, and pathology evaluations to assess bladder cancer staging and muscle invasion status.

1 to 2 visits depending on imaging and pathology procedures

Long-term Monitoring

Duration - 3 months post surgery

Participants are followed postoperatively to evaluate the diagnostic performance of the deep learning models in predicting muscle-invasive status of bladder cancer.

1 follow-up visit at 3 months postoperatively
