A sandwich?like fibers/sponge composite combining chemotherapy and hemostasis is constructed as a postoperative supplement. The implantable cisplatin?loaded fibers/sponge composite (CFSC) is able to simultaneously stop bleeding and absorb disseminated cancer cells after tumor resection. More importantly, sustained released cisplatin can kill residual tumor cells as well as those concentrated in the CFSC, which significantly enhances the antirecurrence and antimetastasis efficiency with low toxicity.Intraoperative bleeding is an essential factor leading to the earliest recurrence and tumor metastasis frequently seen after resection of solid tumors. Local drug delivery implants show the unique advantages on postoperative cancer therapy. Herein, a sandwich?like cisplatin?loaded fibers/sponge composite (CFSC) combining chemotherapy and hemostasis is constructed. The obtained implantable CFSC is able to simultaneously stop bleeding and absorb disseminated tumor cells after tumor resection. More importantly, sustained released cisplatin can kill local residual tumor cells as well as those concentrated in the CFSC, which significantly inhibits local tumor recurrence and distant tumor metastasis on the subcutaneous postoperative recurrence model and metastasis models. This dual functional implant strategy with low toxicity to healthy organs may inspire new aspects for efficient postoperative cancer therapy.
