Objectives
Narrative objectives1
Our objective is to investigate the dynamics of plasma cytokines in patients undergoing cardiac surgery using cardiopulmonary ventilation before and after the use of cardiopulmonary ventilation, and to examine their effects on cancer cells (proliferative capacity, invasive capacity, metastatic capacity) in vitro.

Results
One case was excluded from analysis (failed blood sample collection), and analysis was performed on 8 cases.
Following cardiac surgery under cardiopulmonary bypass, multiple blood growth factors were elevated, suggesting that this effect enhanced the proliferative capacity of pancreatic cancer cell lines. Activation of the VEGF-A/VEGFR2 axis and increased M-CSF levels were presumed to be primarily involved.

Baseline Characteristics
One case of consent withdrawal and one case of unusable blood sample resulted in four males and four females being analyzed. The average age was 61 years.
Participant flow
Informed consent was obtained from the patient the day before surgery. Blood was collected from the patient's arterial line prior to cardiopulmonary bypass. Blood was collected from residual blood in the pump after cardiopulmonary bypass was discontinued.
Centrifugation was then performed to separate the patient's blood into plasma and serum.
Patient plasma was analyzed using a cytokine array. Human pancreatic cancer cells were cultured in patient serum, and proliferation rates were analyzed using an MTS assay.
Adverse events
None
Outcome measures
Growth factors in plasma before and after cardiopulmonary bypass. Proliferation rate of human pancreatic cancer cells cultured in serum before and after cardiopulmonary bypass.
