Establishment and Clinical Assessment of a Prostate Cancer (PCa) Risk Model Based on the Updated Circulating Tumor Cell (CTC) Detection Technique

  1. To elucidate the role of CTC detection in the evaluation of risk level in PCa patients, and establish a mathematic model for predicting the pathological status.
  2. To explore the possible subtle change in CTC condition after radical prostatectomy.

Study Overview

Status

Unknown

Intervention / Treatment

Detailed Description

  1. Detect and evaluate the CTC status (a total of 3 times: 1 day before sugery, 3/12 months after surgery) for all of the PCa patients enrolled. Analyze the CTC result with PSA level, needle biopsy and radiological imaging information.
  2. Analyze the difference in CTC amount/Epithelial-Mesenchymal ratio between patients in different D'Amico risk level(low/intermediate/high).
  3. Establish a mathematic model based on the CTC results and pathological condition observed in operation (OC, organ confined; EPE, extraprostatic extension; SVI, seminal vesicle invasion; LNI, lymph node invasion), and compare this model with the latest version of Partin table.
  4. Detect and compare the CTC and PSA level 3/12 months after surgery. Evaluate the radiological condition in 12 months after blood draw.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Prostate cancer patients
Patients diagnosed with prostate cancer, confirmed with needle biopsy, and suitable for radical prostatectomy, and have not received any treatments before.
Blood draws, from peripheral veins, each time 2 tubes, each 5 ml.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Circulating tumor cell (CTC) total number and epithelial-intermediate-mesenchymal ratio detected by CTC enrichment and FISH technique
Time Frame: 1 day before operation
This step should be completed within the day when the peripheral venous blood is drawn.
1 day before operation
Pathological findings (whether the patient has: 1.OC, organ confined; 2.EPE, extraprostatic extension; 3. SVI, seminal vesicle invasion; 4. LNI, lymph node invasion) during the radical prostectomy, confirmed by pathology section result
Time Frame: On the day of operation
The pathology section evaluation will be done by two pathologists independently. A third pathology expert will join to make a final decision if opposite results are given by the two pathologists.
On the day of operation
CTC total number and epithelial-intermediate-mesenchymal ratio detected by CTC enrichment and FISH technique
Time Frame: 3 months after operation
This step should be completed within the day when the peripheral venous blood is drawn.
3 months after operation
CTC total number and epithelial-intermediate-mesenchymal ratio detected by CTC enrichment and FISH technique
Time Frame: 12 months after operation
This step should be completed within the day when the peripheral venous blood is drawn.
12 months after operation

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Prostate specific antigen (PSA) level measurement using peripheral venous blood
Time Frame: 3 months after operation
The blood should be drawn together with that for CTC detection
3 months after operation
Prostate specific antigen (PSA) level measurement using peripheral venous blood
Time Frame: 6 months after operation
The blood should be drawn together with that for CTC detection
6 months after operation
PSA level measurement using peripheral venous blood
Time Frame: 9 months after operation
The blood should be drawn together with that for CTC detection
9 months after operation
Radiological evaluation including isotope bone scanning and pelvic magnetic resonance imaging (MRI) scan
Time Frame: 12 months after operation
Radiological evaluation should be conducted after the blood is drawn for CTC and PSA detection.
12 months after operation
