a Polyphenol Whole Tumor Cell Vaccine in Patients With Advanced Malignant Solid Tumors

3 patients enrolled in each dose group, and planned dose groups of 5 x 10\*6, 2 x 10\*7, and 5 x 10\*7 cells/dose. The dosing regimen consisted of 5 doses of basal immunization and subsequent individualized treatment. In the basal immunization, the administration times were D0, D14, D28, D42, and D56. After completion of the 5 doses of basal immunization, the subsequent individualized treatment was decided by the investigator based on the subject's tumor assessment, i.e., 1 vaccination per month for a total of 4 doses.
