A review and outlook in the treatment of osteosarcoma and other deep tumors with photodynamic therapy: from basic to deep.Photodynamic therapy, one of the most promising minimally invasive treatments, has received increasing focus in tumor therapy research, which has been widely applied in treating superficial tumors.  However, due to insufficient luminous flux and peripheral tissue damage, the utilization of photodynamic therapy is facing a huge limitation in deep tumor therapy.  In this review, we summarize recent developments in the field of photodynamic therapy and specifically PDT research in OS treatment modalities.

In this review, we summarize recent developments in the field of photodynamic therapy and specifically PDT research in OS treatment modalities.  In addition, we also provide some novel suggestions, which could potentially be a breakthrough in PDT-induced OS therapies.  PDT has the potential to become an effective therapy while the its limitations still present when applied on the treatment of OS or other types of deep tumors.
