As noted by the author in this publication, the reported toxicities are known and anticipated as part of the tace procedure using deb.The events may be related to the doxorubicin, or the resulting necrosis of the tumor treated.The abnormal laboratory values of hyperglycemia, increased alt are sequelae of abnormal liver function, and in addition are not serious injuries.Biloma and liver abscess are known complications associated with the tace procedure.As stated in the literature, the author believed patient selection to be a factor, noting that patients with multiple lesions had a smaller rate of biloma formation than patients with a single lesion.One patient had pre-existing biliary enteric anastomosis which increases the risk of hepatic abscess formation.The authors also believed the injection technique to be a contributing factor to the increased rate of biloma , and adjusted their patient selection criteria and method of administration accordingly.Lot numbers for the devices used were not reported, therefore a quality investigation into the lots cannot be performed.Disease progression occurs in patients with incurable liver cancer and some patients only have partial response to tace, thus the company considered disease progression and therapeutic response decreased not related to lc bead.The use of lc bead loaded with doxorubicin is considered off label use of the device.There was no report of deficiency or malfunction.
