Abstract
- Surgical excision is the first choice for clinical cancer therapy. However, major challenges, such as postoperative tumor recurrence and unsatisfactory wound healing after surgery, remain. In this study, an adhesive hydrogel is developed as a multifunctional platform for antitumor chemoimmunotherapy and postoperative wound treatment. The hydrogel adheres firmly to diverse tissues and degrades within 4 weeks in vivo with good histocompatibility. The immune‐stimulating hydrogel ((DOX+R837@HN)@Gel) is fabricated by encapsulating doxorubicin (DOX) and imiquimod‐loaded HSA nanoparticles (R837@HNs) into the hydrogel. When combined with immune checkpoint blockade (ICB) therapy, intratumorally administering (DOX+R837@HN)@Gel exhibits markedly enhanced systemic antitumor efficacy and strengthened antitumor immunity. For tumor surgical resection, (DOX+R837@HN)@Gel can adhere to the wounds and effectively prevents tumor recurrence and achieves long‐term immune memory with ICB therapy. Moreover, the hydrogel achieves rapid hemostasis and promotes wound healing after treating surgical wound models. Therefore, this multifunctional hydrogel has great significance for clinical postsurgical cancer treatment. [ABSTRACT FROM AUTHOR]
