Details and patient eligibility

About

To evaluate the remission effect and safety of intravenous injection of METR-NK cells as adjuvant therapy on bone marrow suppression in patients with ovarian cancer after chemotherapy

Full description

100 mL METR-NK cells were diluted in 500 mL 0.9% sodium chloride normal saline at 37℃, and the infusion volume of METR-NK cells was not less than 2×107 cells/kg for 1 day as a course of treatment, and the infusion time was maintained for 30 minutes on the 10th day before chemotherapy.
