39 Preliminary Conclusions  High-grade uptake of M1/CM also occurs in metastases with low- grade vascularization.

40 Preliminary Conclusions  High-grade uptake of M1/CM also occurs in metastases with low- grade vascularization.

41 Preliminary Conclusions  Singular arterial supply of metastases is associated with high- grade uptake of M1/CM. S4

42 Preliminary Conclusions  Singular arterial supply of metastases is associated with high- grade uptake of M1/CM. S4

43 Preliminary Conclusions  Multiple arterial supply of metastases is associated with low- grade uptake of M1/CM.

44 Preliminary Conclusions  Multiple arterial supply of metastases is associated with low- grade uptake of M1/CM.

45 Preliminary Conclusions  Multiple arterial supply of metastases is associated with low- grade uptake of M1/CM.

46 Preliminary Conclusions  Multiple arterial supply of metastases is associated with low- grade uptake of M1/CM.

47 Preliminary Conclusions  Multiple arterial supply of metastases is associated with low- grade uptake of M1/CM. S4 multiple feeders

48 Preliminary Conclusions  Preliminary results are encuraging in terms of uptake of Beads® and local tumor response.  Treatment intervals are shorter compared to TACE in HCC.  Median TTP in a salvage situation was 3.0 months.  No complications, tolerable side effects.  Continuation of the studies necessary.

49 Drug eluting Microspheres in CRC Mts.- Questions to answer:  Selective vs. non-selective TACE?  Optimal treatment interval 2…..6 weeks?  Combination with systemic biological Trx. (activation of VEGF and HIF-1)
