An injectable ten percent solution of rose bengal disodium, an iodinated fluorescein derivative, with potential antineoplastic and radiosensitizing activities. When injected into tumor tissue, PV-10 specifically targets and concentrates in tumor cells, producing cytotoxic singlet oxygen when exposed to ionizing radiation. In addition, PV-10 may stimulate an anti-tumor immune response. Check for active clinical trials using this agent. (NCI Thesaurus)
