Abstract
Anticancer drug resistance invariably emerges and poses a significant barrier to curative therapy for various breast cancers. This results in a lack of satisfactory therapeutic medicine for cancer treatment. Herein, a universal vector system for drug-resistance breast cancer was designed to meet the needs of reversed multidrug resistance, thermo-chemotherapy, and long-term drug release behavior. The vector system comprises polycaprolactone (PCL) nanofiber mesh and magnetic nanoparticles (MNPs). PCL has excellent biocompatibility and electrospinning performance. In this study, MNPs were tailored to be thermogenic in response to an alternating magnetic field (AMF). PCL nanofiber can deliver various chemotherapy drugs, and suitable MNPs encapsulated in the nanofiber can generate hyperthermia and synergistic effect with those chemotherapy drugs. Therefore, a more personalized treatment system can be developed for different breast malignancies. In addition, the PCL nanofiber mesh (NFM) enables sustained release of the drugs for up two months, avoiding the burden on patients caused by repeated administration. Through model drugs doxorubicin (DOX) and chemosensitizers curcumin (CUR), we systematically verified the therapeutic effect of DOX-resistance breast cancer and inhibition of tumor generation in vivo. These findings represent a multifaceted platform of importance for validating strategic reversed MDR in pursuit of promoted thermo-chemotherapeutic outcomes. More importantly, the low cost and excellent safety and efficacy of this nanofiber mesh demonstrate that this can be customized multi-function vector system may be a promising candidate for refractory cancer therapy in clinical.

Abstract
Biofunctional surface-modification surpassed critical limitation of graphene oxide (GO) in biocompatibility and drug delivery efficiency, contributing to versatile biomedical applications. Here, a protein corona-bridged GO nanoplatform with high drug loading, longstanding hyperthermia, and controllable drug release, was engineered for amplified tumor therapeutic benefits. Structurally, GO surface was installed with phenylboronic acid (PBA) layer, on which iRGD conjugated apolipoprotein A-I (iRGD-apoA-I) was coordinated via boron electron-deficiency, to form the sandwich-like GO nanosheet (iAPG). The GO camouflaging by iRGD-apoA-I corona provided multimodal high doxorubicin (DOX) loading by π-π stacking and coordination, and generated a higher photothermal transformation efficiency simultaneously. In vitro studies demonstrated that iAPG significantly improved drug penetration and internalization, then achieved tumor-targeted DOX release through near-infrared (NIR) controlled endo/lysosome disruption. Moreover, iAPG mediated site-specific drug shuttling to produce a 3.53-fold enhancement of tumor drug-accumulation compared to the free DOX in vivo, and induced deep tumor penetration dramatically. Primary tumor ablation and spontaneous metastasis inhibition were further demonstrated with negligible side effects under optimal NIR. Taken together, our work provided multifunctional protein corona strategy to inorganic nanomaterials toward advantageous biomedical applications.

Abstract
It remains a major challenge to develop an effective therapeutic system based on gold nanorods (GNRs) for cancer therapy. Herein, we developed a redox-responsive, in-situ polymerized polyplatinum(IV)-coated gold nanorod (GNR@polyPt(IV)) with coupling of the near-infrared (NIR)-induced hyperthermal effect and redox-triggered drug release in one therapeutic platform as an amplifier of tumor accumulation through mild hyperthermia for enhanced synergistical thermo-chemotherapy. After in-situ polymerized with 2-methacryloyloxy ethyl phosphorylcholine (MPC) and Pt(IV) complex-based prodrug monomer (PPM) onto the surface of GNRs, the nanosized GNR@polyPt(IV) exhibited the advantages of high drug encapsulation efficiency, triggered drug release, and reduced side effect. As demonstrated by thermal imaging and photoacoustic imaging in vitro and in vivo, this GNR@polyPt(IV) exhibited an excellent NIR-associated hyperthermal effect and outstanding capacity of tumor accumulation. Importantly, under a mild hyperthermia process, the vascular endothelial growth factor (VEGF) and hypoxia-inducible factor-1α (HIF-1α) were upregulation, resulting in angiogenic vessel around the tumor. Combination with accelerated blood flow and angiogenesis by mild hyperthermia, a dramatic increase of drug accumulation in tumor could be realized after systematic administration. As a result, this amplification fashion of tumor accumulation would contribute the GNR@polyPt(IV) to inhibit tumor progression effectively. Such a facile and simple methodology for enhanced therapeutic effect based on GNRs holds great promises for cancer therapy with further development.

Abstract
Rationale: The development of a highly effective and tumor-specific therapeutic strategy, which can act against the primary tumor and also condition the host immune system to eliminate distant tumors, remains a clinical challenge. Methods: Herein, we demonstrate a facile yet versatile ZnO-capping and Doxorubicin (DOX)-loaded multifunctional nanocomposite (AuNP@mSiO2@DOX-ZnO) that integrates photothermal properties of gold nanoparticles (NPs), pH-responsive properties and preferential selectivity to tumor cells of ZnO QDs and chemotherapeutic agent into a single NP. The photothermal performance, pH-triggered release and preferential phagocytic ability were assessed. The induced anti-tumor immunity was determined by analyzing immune cell profile in tumor in vivo and molecular mechanism were identified by detecting expression of immunogenic cell death (ICD) markers in vitro. Moreover, mice models of unilateral and bilateral subcutaneous melanoma and lung metastasis were established to evaluate the antitumor effects. Results: As an efficient drug carrier, ZnO-capped NPs guarantee a high DOX payload and an in vitro, efficient release of at pH 5.0. In murine melanoma models, the nanocomposite can significantly inhibit tumor growth for a short period upon low-power laser irradiation. Importantly, ZnO NPs not only demonstrate preferential selectivity for melanoma cells but can also induce ICD. Meanwhile, AuNP@mSiO2-based photothermal therapy (PTT) and DOX are directly cytotoxic towards cancer cells and demonstrate an elevated ICD effect. The induced ICD promotes maturation of dendritic cells, further stimulating the infiltration of effector T cells into tumor sites, preventing tumor growth and distant lung metastases. Conclusions: This study highlights the novel mechanism of ZnO-triggered anti-tumor immunity via inducing ICD. Additionally, we shed light on the multifunctionality of nanocomposites in delivering localized skin tumor therapy as well as inhibiting metastatic growth, which holds great promise in clinical applications.

Abstract
Liver cancer is an aggressive malignancy associated with high levels of mortality and morbidity. Doxorubicin (Dox) is often used to slow down liver cancer progression; however its efficacy is limited, and its severe side effects prevent its routine use at therapeutic concentrations. We present a biomimetic peptide that coacervates into micro-droplets, within which both Dox and magnetic nanoparticles (MNPs) can be sequestered. These Dox-loaded Magnetic Coacervates (DMCs) can be used for thermo-chemotherapy, with the controlled release of Dox triggered by an external Alternating Magnetic Field (AMF). The DMCs are internalized by the cells via an energy-independent mechanism which is not based on endocytosis. Application of AMF generates a temperature of 45 °C within the DMCs, triggering their disassembly and the simultaneous release of Dox, thereby resulting in dual hyperthermia and chemotherapy for more efficient cancer therapy. In vitro studies conducted under AMF reveal that DMCs are cytocompatible and effective in inducing HepG2 liver cancer cell death. Thermo-chemotherapy treatment against HepG2 cells is also shown to be more effective compared to either hyperthermia or chemotherapy treatments alone. Thus, our novel peptide DMCs can open avenues in theranostic strategies against liver cancer through programmable, wireless, and remote control of Dox release. STATEMENT OF SIGNIFICANCE: Simultaneous administration of chemical and thermal therapy (thermo-chemotherapy) is more effective in inducing liver cancer cell death and improving survival rate. Thus, there is a keen interest in developing suitable carriers for thermo-chemotherapy. Coacervate micro-droplets display significant advantages, including high loading capacity, fast self-assembly in aqueous environments, and liquid-like behavior. However, they have not yet been explored as carriers for thermo-chemotherapy. Here, we demonstrate that peptide coacervate micro-droplets can co-encapsulate Dox and magnetic nanoparticles and cross the cell membrane. Applying an alternating magnetic field to cells containing drug-loaded coacervates triggers the release of Dox as well as the localized heating by magnetic hyperthermia, resulting in efficient liver cancer cell death by dual thermo-chemotherapy.

Abstract
INTRODUCTION There is increasing evidence that Hyperthermic Intravesical Chemotherapy is an effective treatment for non-muscle invasive bladder cancer (NMIBC). HIVEC (COMBAT BRS system) is an innovative hyperthermia delivering device. The aim of our study is to evaluate tolerance and safety of HIVEC in patients with BCG-refractory NMIBC. MATERIALS AND METHODS In this study, we included 22 patients between January 2017 and April 2018. The treatment consisted in a weekly instillation of Hyperthermic Mitomycin for a total of 6 weeks, with a follow-up every 3 months. In order to evaluate the tolerance, patients filled a questionnaire before each instillation. We analyzed collected data to evaluate safety and efficiency of the treatment after one year. RESULTS Among 22 patients included, no patient suffered from severe side effects. The minor side effects reported were : urinary urgency (40,1 %), urinary pain (40,1%), macroscopic hematuria (4,5%). The IPSS score didn't significantly varied before and after instillations (mean IPSS: 10.8 versus 10.1, p=0.77). The mean follow-up was 11.2 months. The recurrence rate was 27,3% with an average time to recurrence of 7.36 months. Two patients (9.1%) presented a progression to muscle-invasive disease. Four patients (18,2%) had a radical cystectomy. CONCLUSION Hyperthermic Mitomycin using the HIVEC® device is a rather safe and well tolerated treatment. Efficiency remains partial as 27.3% of patients experienced recurrence during the first year. These data should be confirmed by prospective multicentric studies.

Abstract
In this work, a multi-stimuli responsive drug delivery system (MCHP) was designed for combinational chemotherapy and photothermal therapy (PTT). Mesoporous carbon nanoparticles (MCN) with a high loading efficiency were used as near-infrared (NIR)-responsive drug carriers. Human serum albumin (HSA) was attached to the pore openings of MCN via disulfide bonds to serve as a gatekeeper due to its biocompatibility and appropriate molecular size. To improve the dispersity and biocompatibility, the surface of the MCN was modified with polyethylene glycol (PEG). In vitro photothermal effect results showed that MCHP exhibited a power and concentration-dependent photothermal conversion capacity and a good photothermal stability. The doxorubicin (DOX) release from the MCHP/DOX system exhibited NIR/pH/reduction-responsive release properties. A cytotoxicity assay demonstrated that, under NIR irradiation, the MCHP/DOX exhibited chemo-photothermal synergistic effects with a combination index (CI) of 0.643. The biodistribution of DOX in vivo indicated that an NIR laser can prolong the retardation time of DOX in tumor sites. In vivo antitumor experiments showed that MCHP/DOX with NIR irradiation had the highest tumor inhibition rate against 4T1 tumors in mice. This work suggested that MCHP could be explored as a multi-responsive drug release platform for combinational photothermo-chemotherapy.

Abstract
The current chemotherapy method demonstrates the need for improvement in terms of efficacy and safety. Given the beneficiary effect of heat in combination with chemotherapy, the purpose of this study is to develop a multifunctional nanoplatform by co-incorporating gold nanoparticles (AuNPs) as photothermal agent and cisplatin as anticancer drug into alginate hydrogel (named as ACA) to enable concurrent thermo-chemotherapy. The in vitro cytotoxicity experiment showed that the as-developed nanocomplex was able to induce greater cytotoxicity in KB human nasopharyngeal cancer cells compared to free cisplatin at the same concentration. Moreover, the interaction of ACA and laser irradiation acted synergistically and resulted in higher cell death rate compared to separate application of photothermal therapy and chemotherapy. The micrograph of KB cells also revealed that ACA was able to selectively accumulate into the mitochondria, so that laser irradiation of KB cells pre-treated with ACA resulted in intensive morphological damages such as plasma membrane disruption, chromatin condensation, autophagic vacuoles formation and organelle degeneration. Moreover, the sign and magnitude of optical nonlinear refractive index measured by Z-scan technique was shown to be significantly altered in cells exposed to ACA with and without laser irradiation. Consequently, the nanocomplex developed herein could be a promising platform to combine photothermal therapy and chemotherapy effectively, thereby achieving synergistic therapeutic outcome.

Abstract
Locoregional recurrence of breast cancer after tumor resection represents several clinical challenges. Here, we demonstrate that co-delivery of chemotherapy and thermotherapeutic agents by a magnetic supramolecular hydrogel (MSH) following tumor resection prevents tumor recurrence in a breast cancer mouse model. The self-assembled MSH was designed through the partial inclusion complexation associated with the threading of α-CD on the copolymer moieties on the surface of the PEGylated iron oxide (Fe3O4) nanoparticles, which enables shear-thinning injection and controllable thermoreversible gel-sol transition. MSH was injected to the postoperative wound uniformly, which became mobile and perfect match with irregular cavity without blind angle due to the magnetocaloric gel-sol transition when exposed to alternating current magnetic field (ACMF). The magnetic nanoparticle-mediated induction heat during the gel-sol transition process caused the triggered release of dual-encapsulated chemotherapeutic drugs and provided an effect of thermally induced cell damage. The hierarchical structure of the MSH ensured that both hydrophobic and hydrophilic drugs can be loaded and consecutively delivered with different release curves. The hydrogel nanocomposite might provide a potential locally therapeutic approach for the precise treatment of locoregional recurrence of cancer. STATEMENT OF SIGNIFICANCE Tumor recurrence after resection represents several clinical challenges. In this study, we prepared shear-thinning injectable magnetic supramolecular hydrogel (MSH) and demonstrated their therapeutic applications in preventing the post-operative recurrence of breast cancer with facile synthesis and minimally invasive implantation in vivo. MSH was injected to the postoperative wound uniformly, which become mobile and perfect match with irregular cavity without blind angle through magnetocaloric gel-sol transition when exposed to ACMF. The magnetic nanoparticles mediated induction heat during the gel-sol transition process caused the triggered release of dual-encapsulated chemotherapeutic drugs as well as thermally induced cell damage. This study demonstrates that MSH with the controlled administration of combined thermo-chemotherapy exhibit great superiority in terms of preventing post-operation cancer relapse.

Abstract
We report on a 4-year progression-free survival of a 54-year-old female first diagnosed in December 2007 with advanced bilateral ovarian cancer FIGO IIIc, disseminated peritoneal carcinosis and malignant diaphragm invasion. Treatment started in January 2008 with 6 cycles of Taxol 175 mg/m(2)/carboplatin AUC 5 in 3-week intervals. Twenty-four hours following each chemotherapy session, fever-range long-duration whole-body hyperthermia (WBH) was performed at the temperature plateau of 40°C body core temperature for 6 h. Three months after completion of chemotherapy, 4 more long-duration WBH procedures were performed in monthly intervals. Importantly, long-duration WBH was paralleled with intradermal vaccination of autologous dendritic cells. No other treatment was given to the patient. Four years following the first diagnosis, the patient is still in complete remission with no evidence of disease.
