Platelet Activation‐Induced In Situ Trapping Metastatic Tumor Cells Strategy for Post‐Surgery Tumor Recurrence Immunochemotherapy

The reasons for the high recurrence and metastasis after triple-negative breast cancer (TNBC) surgery are the potential presence of micrometastases and disseminated tumor cells in the circulation, as well as the immunosuppressive microenvironment caused by the surgery. To address these issues, this work proposed a platelets (PLTs) based hydrogel delivery system for immuno-chemotherapy, (IL-12+NP
