Comparison of 18FDG-PET-CT images before and 3 months after treatment with 3 cycles of trabectedin. There is expansion of the mass in the pelvis, with reduced 18FDG uptake and formation of a larger cystic/necrotic cavity within the mass. Note the left rib lesion. The PET images and fused PET-CT images are on an identical SUV 0-6 scale.

After 3 cycles of trabectedin, a further 18FDG-PET-CT scan was performed to assess initial response to therapy (fig. 1, right panel). However, on 18FDG-PET-CT there was clear evidence of ongoing disease improvement after 7 months of treatment with trabectedin (fig. 1).
