Outline of Final Research Achievements

Improvements in surgical technique, chemotherapy, and radiotherapy have enhanced the prognosis of patients with malignant bone and soft tissue tumors, but have since reached a plateau in recent years. Novel approaches have been sought but with limited results. On the other hand, several varieties of nanoparticles, including multifunctional nanoparticles, are available that localize the biodistribution of conventional chemotherapeutics to the tumor site. Also, nanoparticles loaded with chemotherapeutic drugs have the ability to overcome drug resistance which is a major obstacle impeding the progress of the treatment. Multifunctional nanoparticles, which have the potential to further augment the bioavailability of drugs, are being actively investigated. The purpose of this study is to investigate in vitro and in vivo therapeutic effects of multifunctional nanoparticles in malignant bone and soft tissue tumors with drug resistance for current chemotherapy.
