Abstract
Colorectal cancer (CRC) is the third most commonly diagnosed cancer among both men and women worldwide. New therapeutic strategies involving cytoreductive surgery and intra-peritoneal chemotherapy could lead to a definitive cure in some cases. However, postoperative intra-abdominal adhesion can cause further complications. In this study, hyaluronic acid (HA)- and carboxymethyl cellulose sodium (CMCNa)-based novel cross-linked hydrogels (HC hydrogels) were synthesized and fully characterized. We demonstrated that varied compositions of HA and CMCNa altered the microstructure, rheology, and degradation behavior of hydrogels. Pre-constructed hydrogels were further loaded with oxaliplatin to prevent intra-abdominal adhesion following chemotherapy. Sustained release of oxaliplatin was observed from hydrogels compared that from solutions, which release drugs through diffusion, following the Higuchi and Korsmeyer-Peppas models. Moreover, low adhesion scores in an in vivo SD rat model demonstrated inhibition of intra-peritoneal adhesion in response to HC hydrogels. Therefore, HC hydrogels offer a novel formulation strategy for providing an intra-abdominal anti-adhesion barrier after cytoreductive surgery and intra-peritoneal chemotherapy for CRC treatment.
