TFC Star Tsubasa Endoh Announces Retirement After Leukemia Battle

<span>TFC</span> player Tsubasa <span>Endoh</span>, 31, who was diagnosed with <span>acute undifferentiated leukemia</span> in December 2021, has retired as a Toronto FC player. 

On Friday, Toronto announced that it had signed Endoh to a one-day contract to officially retire as a TFC player. He had also been honored before Saturday's game against Atlanta United. Toronto GM Jason Hernandez in a state said, "It is truly a special moment for Toronto FC to have Tsubasa come back and officially retire as a Red. The club wanted to give him this recognition for all his contributions over six years and celebrate his career."

His contract with TFC had expired following the 2021 season, after that he signed Melbourne City FC in Australia's A-League in early 2022. It was later the same year when he joined Los Angeles Galaxy reserve side. It was when he was in LA that his body was malfunctioning. 

Blood work showed an alarming white blood cell count. A trip to ER then turned into an 8-day hospital stay, it was there when he was told that he may have <span><a href="https://www.healthandme.com/health/cancer">cancer</a></span>. He returned to Japan to be with his family and was diagnosed with the rare form of leukemia. 

He is also battling a lot of other things on the side, like it is said that cancer does not come alone. His battle also includes chronic GvHDs (graft-versus-host disease), a systemic disorder occurring when immune cells from transplanted tissue recognize the recipient's body as foreign and attack its cells.

He has also been through four rounds of chemotherapy until now, radiation and also a bone marrow transplant. However, during his last round of chemotherapy, which lasted for 8 weeks, no visitor was allowed. 

"You spend so much time alone … It's not easy," he said. "The silver lining was to get all the support from TFC fans and the Galaxy, the guys from Maryland."

He is also suffering from debilitating body cramps and is currently on 15 different medications. He also is suffering from fascia inflammation (fascia is the thin cover of tissue that holds muscles in place), which means picking something up on the floor can be difficult because his muscles tighten so much. He sometimes has to stop typing when his fingers cramp. Putting on socks is painfully hard, reports TSN. 

"Those are the little things that add up. But this is my life now. I try not to focus on negative things in life. It's what it is. You just have to adapt and accept it," he says. 

<h2>What Is Acute Undifferentiated Leukemia?</h2>

As per the National Cancer Institute, USA, leukemia is a broad term for cancers of the blood cells. The type of leukemia depends on the type of blood cell that becomes cancer and whether it grows quickly or slowly. Leukemia occurs most often in adults older than 55, but it is also the most common cancer in children younger than 15.

However, acute undifferentiated leukemia is different, notes the American Society of Hematology (ASH). The ASH publication from 2019, notes that it is a rare and by definition, has neither lymphoid nor myeloid lineage specific markers. Given its rarity, little is known about its incidence, survival, and optimal management. 

National Cancer Institute's Surveillance, Epidemiology, and End Result Program (SEER), notes that this cancer affects the bone marrow and peripheral blood. There are too few cases to know whether there is a predilection for other sites. These leukemias are very rare and nothing substantial is known about their frequency. While anecdotal experience generally considers these leukemias to be of poor prognosis, information is too scanty to make any definitive statements.

The National Institute of Health (NIH), USA also notes that there are no established treatment for this condition. However, chemotherapy, allogenic hematopoietic stem cell transplantation, radiation, etc. could work, but an optimal strategy remains undefined due to rarity of this cancer.
