| 内容記述 | Poupose: To determine if Cu-62 labeled diacetyl-bis (N (4)-methylthiosemicarbazone); (Cu-62-ATSM) imaging of tumor hypoxia is associated with C-11-methionine(MET) imaging of amino acid metabolism in cervical cancer. \nMethod: PET/CT was performed in ten patients with cervical cancer for evaluation of both tumor hypoxia using Cu-62-ATSM and amino acid metabolism using MET. Histologically confirmed eight squamous cell carcinoma, four adenocarcima, two adenosquamous carcinoma and melanoma were enrolled in this study. Distribution of Cu-62-ATSM in tumor was compared with that of MET. The two-group system was evaluated the distribution of uptake as Matched (mostly matched with each other) and Mismatched (with each other). Tumor uptake of each tracer was also analyzed semi-quantitatively by Tumor-to-Normal-Tissue-Ratio (TNR). \nResult: Matched and Mismatched-groups were 1 case (6.7%) and 14 cases (93.3%), respectively. In Mismatched-group, Cu-62-ATSM tend to accumulate around the distal margin of high MET uptake area in the tumor. Mean TNR was 9.5 in MET and 4.0 in Cu-62-ATSM, and thus image contrast between tumor and surrounding normal tissue was higher in MET PET/CT image than Cu-62-ATSM PET/CT image. \nConclusion: Cu-62-ATSM and MET showed different distribution in most cases of cervical cancer. Cervical cancer had a greater tendency for the uptake of MET than Cu-62-ATSM. |
