Application of a Novel Model Based on Plasma cfDNA Assay and MRl Lmaging in the Detection of Prostate Cancer

The goal of this diagnostic test is to obtain multiple cell-free DNA （cfDNA） fragment profiles of subjects by whole genome sequencing based on plasma cfDNA, build a prostate cancer prediction model by machine learning, and to validate the efficacy of this model in patients who need to undergo needle prostate biopsy base on their prostate-specific antigen（PSA） or clinical or imaging evidence. Therefore, this study aims to explore the efficacy of this prostate cancer prediction model in distinguishing between patients with PSA "gray zone" (4-10 ng/ml) in the diagnosis of prostate cancer and patients with clinically significant prostate cancer.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Inclusion Criteria:

  1. Male, 18-80 years old;
  2. PSA: 4-10ng/ml;

  3. Patients scheduled for prostate biopsy：

    • fPSA（free PSA）/PSA < 0.16 or PSAD（PSA density） > 0.15 (ng/mL/cm³) or PSAV（PSA velocity） > 0.75 (ng/mL/year) ② positive DRE （digital rectal examination） ③suspicious positive lesions on ultrasound/MRI).

Exclusion Criteria:

  1. Patients with a prior diagnosis of any malignancy within 5 years;
  2. Patients who have undergone prior transurethral resection or enucleation of the prostate;
  3. Patients who have received prior treatment for prostate cancer, including but not limited to endocrine therapy, targeted therapy, and immunotherapy;
  4. Patients with long-term use of anticoagulant and antiplatelet aggregation drugs (anticoagulant discontinued for less than 1 week);
  5. Received any form of oncological treatment, including surgery, radiotherapy/chemotherapy, endocrine therapy, targeted therapy, and immunotherapy prior to enrollment for blood sampling;
  6. concurrently suffering from other serious systemic diseases that, in the opinion of the investigator, may interfere with the treatment, evaluation and compliance of this trial, including serious respiratory, circulatory, neurological, psychiatric, gastrointestinal, endocrine, immune, urinary and other systemic diseases;
  7. Organ transplant recipients or prior non-autologous (allogeneic) bone marrow or stem cell transplant population;
  8. Subjects who have had a blood transfusion 1 month prior to the blood draw;

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Patients with elevated PSA test results (4-10ng/ml)
Diagnostic test: Blood draw and MRI scans

Before undergoing a prostate biopsy, participants will have about 10 mLs of venous blood drawn. Blood will be sent to Geneseeq Technology Inc. for whole genome high-throughput sequencing of plasma cfDNA.

MRI scans obtained prior to prostate biopsy will be collected following informed consent.
