Neoadjuvant transcatheter arterial chemoembolization and systemic chemotherapy for the treatment of undifferentiated embryonal sarcoma of the liver in children

Figure 1 Transcatheter arterial chemoembolization procedure of case 6. A: The catheter was introduced into the tumor-feeding artery and performed angiography, showing the stereoscopic configuration of "holding ball"; B: After injection of anticarcinogen and lipiodol, the outline of the entire tumor was revealed.

Figure 2 The imaging manifestation of case 6. A and B: Computed tomography scans showed a giant mass of the right liver (diameter 14.8 cm); C and D: One month after neoadjuvant therapy: The tumor volumes shrunk by 48.8%, lipiodol deposits in the tumor with a clear boundary; E and F: One month after tumor resection.

Figure 3 These are conducive to complete resection, reducing the rate of positive surgical margins, and diminishing intraoperative bleeding. A: The gross of tumor appears as border clear with about 10 cm in diameter; B: The cut surface is red, brown or yellow and has soft qualitative with focal necrosis.
