The common seen treatment of oral cancer are surgery, radiation and chemical drugs. In order to achieve the postoperative wound healing and prevent the recurrence of oral cancer, we used anti-cancer drugs coating in our base material as a non-invasive oral cancer treatment patch. In this study, we used gellan gum (GG) and hyaluronic acid (HA) compound (GH) as a base material to prepare a degradability film, furthermore based on the anti-cancer mechanism of clioquinol (CQ) and 5-fluorouracil (5-FU) from literatures, which can applied on oral cancer treatment, then we will investigated the mechanical properties, drug release kinetic, inhibitory concentration (IC50), in vitro and in vivo studies. The gel content results of GG film and GH film are 87.35% and 84.5%, respectively; water content results are 82.78% and 88.54%, respectively. FTIR shown the signal have discrepancy between before and after cross-linking, but the drugs did not have an effect on cross-linking. The mechanical properties shown GH films more stronger than GG films，are 3.1±0.1kgf and 2.8±0.07kgf, respectively. The accumulative release of GG/CQ and GH/CQ film are 40%, whereas GG/5FU and GH/5FU films are 17% and 12%, respectively. Finally, we evaluate the film by set up animal model.結冷膠透明質酸Clioquinol5-FluorouracilGellan gumHyaluronic acid5-Flurouracilthesis
