A Trial to Evaluate the Effect of Applying Leukapheresis to Enrich CTCs in mPCa Patients
China50 participantsStarted 2024-06-25
Plain-language summary
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.

Inclusion criteria
ā. male, aged 18-75 years; and
ā. 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;
ā. Good general condition, ECOG score 0-1, able to tolerate leukapheresis;
ā. Normal haematological analysis, liver and renal function tests at screening;
ā. Subjects (or their legal representatives) can understand the informed consent form.
Exclusion criteria
ā. those who have received systemic combination therapy for tumours within 5 years;
ā. those with poor general condition, severe haemodynamic instability, malignant arrhythmias, cachexia and infections
ā. those with coagulation disorders, DIC or reduced platelets;
What they're measuring
1
Number of circulating tumor cells
Timeframe: The leukapheresis takes about 2 hours, and CTCs number will be measured in 24 hours after sampling.
