FIGURE 1. (A) Normal cervical specimen from patient with uterine myoma, in which little Glut-1 was found in basal layer. (B) Patient with CIN-III and cervical specimen showed minimal expression of Glut-1 in its dysplastic cells. (C) Patient with stage IIB bulky cervical cancer. Overexpression of Glut-1 in cervical cancer tumor was observed, mainly in cervical cancer cell membrane. (D) Patient with cervical cancer who had previous radiation therapy and central recurrence. 18F-FDG PET scan was false-negative and only minimal Glut-1 expression was observed in specimen.

FIGURE 2. Results of comparative analysis of primary and recurrent or persistent tumor from dual-phase 18F-FDG PET scans. Highly positive correlation between SUV1 and SUV2 was observed for primary tumor (r = 0.832, P < 0.001) and recurrent or persistent tumor (r = 0.973, P < 0.001).

FIGURE 3. Results of comparative analysis of maximum SUV from dual-phase 18F-FDG PET scans and results of immunohistochemical staining. There is significant positive relationship of SUVs with Glut-1 expression (r = 0.74, P < 0.001 for SUV1; r = 0.65, P < 0.001 for SUV2).

FIGURE 4. Comparison of results from work of Higashi et al. ( ) and our data (); slope of relation between Glut-1 expression and maximum SUV from dual-phase 18F-FDG PET scans is steeper for lung cancer than that for cervical cancer and correlation coefficients are larger (r = 0.74, P < 0.001 vs. r = 0.55, P < 0.001).

FIGURE 5. If results for SUL are used in place of maximum SUV, our data () for cervical cancer show more significant correlation than data of Brown et al. ( ) for lung cancer (r = 0.504, P < 0.001 vs. r = 0.007, P < 0.976).
