Outline of Final Research Achievements |
18F-fluoromisonizazole (F-MISO) PET/CT is a non-invasive method of depicting tumor hypoxia. A prospective clinical trial of F-MISO PET/CT for patients scheduled for radiotherapy (RT) was conducted. F-MISO above a value of 1.60 SUV was regarded as indicating a hypoxic area based on our previous study. Of the 22 tumors examinied, 18 tumors had hypoxic area before RT. For 17 patients, F-MISO PET/CT was performed twice before and during fractionated RT. Except for one nasopharyngeal cancer, 16 of the 17 tumors showed a decrease in hypoxic indicators, indicating reoxygenation. Local control rate of patients with SUVmax <2.0 was significantly better than that of patients with SUVmax =>2.0 (p=0.03). Also, overall survival rate of patients with SUVmax <2.0 was significantly better than that of patients with SUVmax =>2.0 (p=0.004). In conclusion, most human tumors contain hypoxic areas before treatment. F-MISO SUVmax =>2.0 before treatment may predict poor prognosis by RT.
