| 内容記述 | PURPOSE:C-11 methionine is a tracer for PET that can be used to assess metabolism of amino acid in tumor cells. The purpose of this study is to assess the ability of C-11 methionine PET (MET-PET) to predict prognosis of patient with adenocarcinoma in head and neck treated by carbon ion radiotherapy (CIRT). METHOD AND MATERIALS:We studied consecutive 23 patients with proven adenocarcinoma in head and neck who had been referred to our hospital for CIRT. 15 patients were male and 8 patients were female. The average patient age was 61.9 years (range 40 to 82). Patients were followed for 5.1 to 89.8 months (mean: 31.9 months) after CIRT. We evaluated the lesion semi-quantitatively on the basis of the Tumor-to-Normal-tissue Ratio (TNR). We statistically analyzed the relationship between tumor MET uptake level at pre and post CIRT, recurrence or metastasis rate, and patient prognosis using Kaplan-Meier analysis method. RESULTS:There were significant relationships between the level of tumor activity before CIRT and patients prognosis, recurrence and metastasis rate (p=0.029, 0.043, and 0.014) from Kaplan-Meier analysis. The level of tumor activity after CIRT also significantly related to patients prognosis, recurrence and metastasis rate (p=0.049, 0.043, and 0.014). No statistically significant relationship was observed between tumor uptake change after CIRT and survival rate. CONCLUSIONS:MET-PET is useful to predict patients survival rate, recurrence and metastasis rate in patients with head and neck adenocarcinoma treated by CIRT. |
