Featured product: LifePearl™ Drug Elutable Microspheres
Despite the introduction of new chemotherapeutic agents and the development of locoregional therapies, there is still a lack of standardized evidence-based protocols for optimal Colorectal cancer with Liver metastases (CRC-LM) management
To evaluate prospectively the efficacy and safety profile of chemo embolization with drug eluting microspheres alone (DEM-TACE) vs DEM-TACE followed by bevacizumab in patients with mCRC (DEM-TACE-B).
Single center study.
Patients groups were divided per patient decision to DEM-TACE alone vs DEM-TACE + bevacizumab (DEM-TACE-B)
Treatment was performed using 2 ml of 100µm LifePearl™ microspheres loaded with irinotecan (100 mg)
For the DEM-TACE-B group, bevacizumab therapy was started 15 days after the first TACE at a concentration of 5 mg/kg and was repeated every 2 weeks for a total of eight cycles.
Tumor response was evaluated with RECIST1.1
A total of 30 patients with CRC-LM were included. TACE alone (17), and TACE-B (13)
DEM-TACE-B 12 months (range 7-22)
DEM-TACE 5.8 months (range 1.5-7.7) (p<0.01)
Progression Free Survival (PFS):
DEM-TACE-B: 6 months (range 3-18
DEM-TACE: 4 months (1.5-7.7) (p<0.01)
Time to progression (TTP):
DEM-TACE-N:4.5 (3-9) months
DEM-TACE: 2.9 (1.5-6.4) months (P=ns)
DEM-TACE-B was well tolerated
Reported adverse events were mostly related to post-embolization syndrome and grade 1-2
The main limitations of this report were the small number of patients enrolled and the number of centers involved. Further randomized multicentric studies with a larger number of patients are necessary to confirm these data on the association of TACE with angiogenesis inhibitors in for the treatment of refractory CRC-LM.
Fiorentini et al concluded that the results of the study suggest that the combination of TACE with intravenous bevacizumab is effective, feasible, and well-tolerated by patients with CRC-LM and may potentially have more benefits concerning tumor response and survival than TACE alone.
According to Fiorentini et al, the preliminary results of the study showed that the transarterial treatment with LifePearl microspheres loaded with irinotecan in combination with Bevacizumab is feasible and tolerable treatment with good efficacy results.

European Economic Area Indications for use
LifePearl™ microspheres are indicated for embolization of blood vessels supplying primary hypervascular tumours or metastases in the liver. Note: LifePearl™ microspheres can be loaded with chemotherapeutic drugs. When used for drug loading, drug loading should be done under a physician's direction, choice and responsibility, based on type and dose of drug most beneficial to the patient. LifePearl™ microspheres are compatible with doxorubicin, epirubicin idarubicin and irinotecan. LifePearl™ microspheres can be drug loaded prior to embolization and then, as a secondary action, elute a local, controlled, and sustained dose to the targeted tumour sites after embolization. LifePearl™ microspheres are not available for sale in all countries. This information is provided only in respect to markets where this product is approved or cleared.
