SK-NK Injection in Patients With Advanced Solid Tumors Accompanied by Malignant Ascites

In this stage, two dose groups are preset, namely 20×108 cells and 30×108 cells. Subjects who meet the inclusion criteria will receive intravenous infusion of SK-NK injection once a week for six consecutive times. After completing six consecutive infusions of SK-NK injection, the researchers evaluated that the patient benefited and could continue to receive six consecutive infusions of SK-NK injection. After completing twelve infusions, the decision on whether to continue the treatment subsequently could be made based on the patient's condition
