A Trial to Evaluate the Effect of Applying Leukapheresis to Enrich CTCs in Patients With Metastatic Prostate Cancer

The goal of this observational study is to compare the number of CTCs enriched by both sampling methods, leukapheresis and collection of peripheral blood in metastatic prostate cancer patients. The main questions it aims to answer are:

  1. The advantages and disadvantages of two sampling methods for further diagnosis and treatment;
  2. How to obtain further information on the tumour biology of CTC;
  3. The mechanisms of prostate cancer invasion and metastasis Participants will have 7.5mL of peripheral blood taken as well as undergo leukapheresis.

  5. Previous medical history and treatment history.

Description

Inclusion Criteria:

Evidence of metastasis (positive finding of metastasis on one of the following tests: CT and MRI; whole-body nuclear bone imaging, fluoride PET and PET-CT, cholinergic PET-CT and MRI; prostate-specific membrane antigen-targeted PET-CT); or clinical diagnosis of metastatic prostate cancer (tumour stage of T3 and above) by pathology of aspiration/surgical biopsy;
  3. Good general condition, ECOG score 0-1, able to tolerate leukapheresis;
  4. Normal haematological analysis, liver and renal function tests at screening;
  5. Subjects (or their legal representatives) can understand the informed consent form.

Exclusion Criteria:
