10 More CT More PET Same Lesion

11 SUV on a Fusion Image - anywhere you point the mouse All areas of tumor not alike: heterogeneity of edges of tumor vs middle of tumorAll areas of tumor not alike: heterogeneity of edges of tumor vs middle of tumor Areas near or in vital structures (e.g. spine, mediastinum, liver, chest wall)Areas near or in vital structures (e.g. spine, mediastinum, liver, chest wall) Ossified lesions may have small “islands” of intense FDG uptake (incomplete response to chemotherapy, focal relapse)Ossified lesions may have small “islands” of intense FDG uptake (incomplete response to chemotherapy, focal relapse) All areas of tumor not alike: heterogeneity of edges of tumor vs middle of tumorAll areas of tumor not alike: heterogeneity of edges of tumor vs middle of tumor Areas near or in vital structures (e.g. spine, mediastinum, liver, chest wall)Areas near or in vital structures (e.g. spine, mediastinum, liver, chest wall) Ossified lesions may have small “islands” of intense FDG uptake (incomplete response to chemotherapy, focal relapse)Ossified lesions may have small “islands” of intense FDG uptake (incomplete response to chemotherapy, focal relapse)

13 MIMvista PET-CT Fusion Examples OsteosarcomaOsteosarcoma EwingsEwings OsteosarcomaOsteosarcoma EwingsEwings

14 Chest Wall Osteosarcoma: Progression after HD-Ifosfamide L pleural/chest wall disease unresectable

15 CT after Doxil +Avastin: Ossification Was 7 Now 4 (pleural Effusion better)

16 PET: Avid Hmmmm……

17

18 PET-CT Fusion: SUV less SUV was >5

19 Local Control: Samarium + RT Samarium scan and RT plan

20 After Samarium +RT (SUV less; No new lesions)

21 No longer next to heart s/p RT Continues on L-MTP-PE (Junovan) CIND “stable” by RECIST Better on PET-CT

22 Osteosarcoma of Ilium + Sacrum Excellent function, no pain 8 months s/p Proton RT now NED s/p staged thorocotomies:? “CR” on PET-CT

23 Osteosarcoma: Pelvic sidewall RFA- pain gone, no progression at this site; attends High School - Will follow with bone scan and PET-CT

24 Metastatic Osteosarcoma: Identification of Active Primary SUV 5.9 Bone scan not avid Where PET was avid

25 PET- “avid” +bone scan, too PET-CT showed local recurrence (posterior-lateral SUV 8.1= tumor) Artifact on MRI and CT s/p limb salvage

26 Local Recurrence: Fusion Image

27 Right Hilar Osteosarcoma (RT w/o chemo, then chemo-- not enough : now needs surgery)

28 Osteosarcoma s/p Pneumonectomy Stable – Low SUV in R thorax; continues off all therapy

29 Response Quality: 1 Year after Samarium- Tumor Islands Active “islands” also seen in primary extremity lesions

30 Osteosarcoma of Sacrum Clinical Response S/P HD-Ifos and RT (pain gone and NO symptoms x1 yr)

31 Osteosarcoma Relapse- Sacrum (SUV 5.4 at start of HDIFOS )

32 Sacral Osteosarcoma (SUV 1.9 s/p IFOS) NO change in size on CT; slightly less avid on bone scan Pain gone + clinical response to HD-IFOS

33 EWS- s/p 3 cycles TMZ + Irinotecan Began short of breath with massive disease- clinically much better

34 Stopped TMZ + Irinotecan : Relapse Given RT, this lesion ok. Stopped Rx again. Increase LUL nodule

35 EWS: Clinical Response Now Off TMZ + irinotecan X 5 months
