Knowing the tumor type helps them know which treatments are most likely to work well.</p> <h3>How Is Undifferentiated Embryonal Sarcoma of the Liver (UESL) Treated?</h3> <p>Doctors usually use a combination of different treatments for UESL, such as:</p> <ul> <li>surgery to remove the tumor from the liver</li> <li>a <strong><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/liver-transplant.html/">liver transplant</a></strong> if the tumor cannot be removed with surgery</li> <li><strong><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/chemotherapy.html/">chemotherapy</a></strong> (treatment with medicines to shrink the tumor)</li> <li><strong><a href="https://kidshealth.org/en/parents/radioembolization.html" onclick="window.open(this.href, 'windyWindow', 'width=800,height=600,status=no,scrollbars=yes,toolbar=no,resizable=yes,location=yes'); return false;">transarterial radioembolization with Yttrium-90 (TARE-Y90)</a></strong>, which delivers a high dose of <strong><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/radiation.html/">radiation therapy</a></strong> directly into the tumor(s)</li> <li>bland embolization, which uses small particles to shut off the blood supply to the tumor</li> <li>tumor ablation , which kills tumors using small needles to heat or cool them</li> </ul> <h3>Who Treats Undifferentiated Embryonal Sarcoma of the Liver (UESL)?</h3> <p>Undifferentiated embryonal sarcoma of the liver is treated by a health care team, including specialists in:</p> <ul> <li>oncology (cancer)/hematology (blood diseases)</li> <li>surgery</li> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/intvnl-radiology.html/">interventional radiology</a> (image-guided <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/endoscopic.html/">minimally invasive</a> procedures)</li> <li>gastroenterology (digestive tract) and hepatology (liver)</li> <li>pathology (diagnosing diseases by examining body tissues, fluids, and organs )</li> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/about-genetics.html/">genetics</a> (genetic counseling and <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/genetics.html/">genetic testing</a>)</li> <li>radiology (medical imaging)</li> <li>nutrition</li> </ul> <h3>What Else Should I Know?</h3> <p>UESL tends to grow quickly, but treatment for this cancer is improving.&nbsp;</p> <p>If your child has UESL, work with the care team to get the best treatment.
