biopsy (removing a small piece of tissue using surgery or a needle with imaging guidance)
Doctors study the biopsy sample to see if the tissue is a . If it is, the biopsy also can show the type of liver tumor. Knowing the tumor type helps them know which treatments are most likely to work well.
How Is Undifferentiated Embryonal Sarcoma of the Liver (UESL) Treated?
Doctors usually use a combination of different treatments for UESL, such as:
Surgery is the most important part of treatment, but many UESL tumors can't be removed easily. A liver transplant may be considered because the whole liver needs to be removed to get the entire tumor out.
Chemotherapy is often used but doesn't always shrink UESL.
Radioembolization (or Y90) is a type of therapy that delivers high-dose radiation directly to the liver tumor through the bloodstream. The radiologist inserts a tiny catheter (plastic tube) in the groin and passes it to the artery closest to the tumor. This procedure protects much of the normal liver tissue from the effects of Y90.
Y90 can be used as primary therapy in liver tumors that don't respond well to chemotherapy. It's also used when the tumors come back or don't shrink enough for surgery.
Transarterial chemoembolization (TACE), which sends chemotherapy particles directly to the tumor.
Tumor ablation, which is when doctors destroy tumors by using small needles to heat or cool them.
