Brief summary

This is a proof of concept study with the purpose of examining the anti-tumour immune response after local irreversible electroporation (IRE) in patients with prostate cancer. Who is it for? You may be eligible for this study if you are male, aged 18 years or over, have prostate cancer, and scheduled for either IRE or radical prostatectomy. Study details There will be two groups of participants: patients scheduled for IRE, and patients scheduled for radical prostatectomy. Both groups of participants will undergo their scheduled treatment as usual. In addition, both groups will have blood samples collected before treatment, and on days 3, 14 and 30 after treatment. It is hoped that this research will improve understanding of systemic anti-tumour immune response after IRE, and thus offer insight for future cancer treatment strategies.

Interventions

This project is a single-centre proof of concept study conducted at St Vincent’s Private Hospital, Sydney (Patient recruitment and treatment centre). Patients that are planned for focal irreversible electroporation (IRE) also known as NanoKnife procedure will undergo venous blood collection prior to treatment (baseline) and 3, 14 and 30 days post IRE. The immunological response following IRE will be compared to patients that are treated by radical prostatectomy and have had blood collected at th

Patients that are planned for focal irreversible electroporation (IRE) also known as NanoKnife procedure will undergo venous blood collection prior to treatment (baseline) and 3, 14 and 30 days post IRE. The immunological response following IRE will be compared to patients that are treated by radical prostatectomy and have had blood collected at the same time points, to assess whether there is an ongoing systemic anti-tumour response. Blood tests will only be used for the purpose of the study analysis and will not affect patient treatment
