About this study

In this study, investigators plan to conduct the 3D in vitro culture PTC drug sensitivity testing of fresh tumor specimen which obtained by endoscopic biopsy or other methods. Through assessing the consistency between the testing results and the patients' neoadjuvant treatment outcomes, they would evaluate the accuracy of PTC drug sensitivity testing and its application value in the individualized precision medicine for muscle-invasive bladder carcinoma.

Read the detailed description

This is a prospective observational study. In this study, researchers propose to enroll 40 participants above 18 years of age with muscle-invasive bladder carcinoma, who are going to receive the neoadjuvant therapy before surgery. Collecting fresh tumor samples for PTC drug sensitivity testing, conducting neoadjuvant therapy for the subjects simultaneously. By combining PTC prediction results with the patients' clinical treatment process and medication feedback, researchers could estimate the accuracy of PTC drug sensitivity testing. Completion of this research would provide real-world figures to support for the clinical application for PTC drug sensitivity testing, and a method is going to be established to guide the clinical treatment regimen for patients with muscle-invasive bladder carcinoma.

Being tested

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Complete Response (CR)

    Disappearance of all target lesions. Any pathological lymph nodes(whether target or non-target)must have reduction in short axis to <10 mm. Length is measured in millimeters, refers to RECIST 1.1.

    Measured: 3 months

  2. Partial Response (PR)

    At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Length is measured in millimeters, refers to RECIST 1.1.

    Measured: 3 months

  3. Progressive Disease (PD)

    At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study(this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm.(the appearance of one or more new lesions is also considered progression). Length is measured in millimeters, refers to RECIST 1.1.

    Measured: 3 months

  4. Stable Disease (SD)

    Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study. Length is measured in millimeters, refers to RECIST 1.1.

    Measured: 3 months
