Abstract
Personalized medicine is an important treatment approach for diseases like cancer with high intrasubject variability. In this framework, printing is one of the most promising methods since it permits dose and geometry adjustment of the final product. With this study, a combination product consisting of anticancer (paclitaxel) and antiviral (cidofovir) drugs was manufactured by inkjet printing onto adhesive film for local treatment of cervical cancers as a result of HPV infection. Furthermore, solubility problem of paclitaxel was overcome by maintaining this poorly soluble drug in a cyclodextrin inclusion complex and release of cidofovir was controlled by encapsulation in polycaprolactone nanoparticles. In vitro characterization studies of printed film formulations were performed and cell culture studies showed that drug loaded film formulation was effective on human cervical adenocarcinoma cells. Our study suggests that inkjet printing technology can be utilized in the development of antiviral/anticancer combination dosage forms for mucosal application. The drug amount in the delivery system can be accurately controlled and modified. Moreover, prolonged drug release time can be obtained. Printing of anticancer and antiviral drugs on film seem to be a potential approach for HPV-related cervical cancer treatment and a good candidate for further studies.

Abstract
The use of nanomaterials as drug delivery systems shows good effects in treating tumors. However, the effective dose of drugs targeted to tumor tissues is very low because of the effect of the reticuloendothelial system (RES) in removing such foreign substances. In order to eliminate the RES effect, we developed mPEG-PLGA@ZrO2@(DOX + ILS) (mPEG-PLGA@ZrO2@[DOX + ILS]) drug-loaded microspheres. These microwave (MW)-sensitized microspheres directly embolized the blood-supply vessels of tumors to induce tumor ischemia and hypoxia, as well as to aggregate drugs within tumor tissues in a long-lasting manner. Additionally, combination with MW ablation can triple the effects for the inhibition of tumor growth. The MW sensitive ionic liquid (ILS) in microspheres can rapidly produce a high temperature in a MW field on the basis of MW sensitization, thus accelerating the degradation of microspheres to release DOX-loaded ZrO2 into the lesions to kill tumors. Microspheres can also prolong the pharmacological time and effect of drugs through the enhanced permeability and retention (EPR) effect of nanocarriers, as well as the sustained release of nanomaterials. Studies performed in vivo revealed that mPEG-PLGA@ZrO2@(DOX + ILS) showed good biosafety. We undertook sensitized microsphere embolism therapy using novel mPEG-PLGA@ZrO2@(DOX + ILS) microspheres in a rabbit VX2 liver tumor model. Three, 6 and 9 d after treatment, computed tomography indicated no significant change in tumor size, and diffusion weighted imaging showed a marked decrease of residual tumor tissues. With the multiple functions of inducing embolisms, sensitization, and the sustained release of chemotherapeutics, novel mPEG-PLGA@ZrO2@(DOX + ILS) microspheres can achieve good therapeutic efficacy, in combination with MW ablation and chemotherapy, while embolizing the blood vessels of arterial tumors.
