The surgical procedure. A Tumor resection and hydrogel platform injection procedure. a Surgery was performed; b Mimicked incomplete tumor removal; c The hydrogel platform was injected into the tumor cavity;d The wound was closed. Strategies to control resected tumor size: B Tumor volume was accurately recorded before surgery, and mice with similar tumor volume were selected for randomly grouping; C A single experimenter performed the surgery to remove about 90% of the tumor volume; D Resected tumors were weighed and photographed to ensure the size of the residual tumors in each group are relatively uniform
