Patients are categorized depending on their white blood cell count into low, intermediate, and high risk. Depending on their category, the treatment may vary.
The most important non chemo drug given is ATRA (all-trans retinoic acid), a vitamin A derivative that is administered orally. ATRA targets and eliminates the PML/RARα abnormality. It could be combined with:
- Arsenic trioxide (ATO), another non-chemo drug, that is given intravenously. Studies found out that a combination of ATRA and ATO stays superior to classic chemotherapy, especially for children. Therefore, APL can be cured without the use of chemotherapy, making it gentler for the body and thus less risky for side effects. A majority of doctors considers it the most effective therapy. This treatment is mostly used on low and intermediate risk patients.
- Chemotherapy with an anthracycline drug. These chemotherapy agents interact directly with the DNA in the nucleus of leukemic cells, interfering with cancer cell survival. It is mostly used on high risk patients.
- Chemotherapy (an anthracycline) and ATO
An allogeneic bone marrow transplant, like Kate Fritzgerald received from her sister Anna, means she couldn’t provide the bone marrow for herself and thus relied on another person to donate. The recovery expectancies for allogeneic transplants are quite high, so Kate marks one of the few cases that relapse. Additionally, APL is considered the most curable form of adult leukemia since the discovery of ATRA. Hence it can be concluded that Kate Fritzgerald marks a unique case, especially since APL is one of the rarest subforms of cancer.
Have you ever thought about suing your parents? You would think such a thought would never actually become reality, no way how you would twist it. However, a girl called Anna Fitzgerald did. She was born with the only purpose to sacrifice herself to save her sister: And now she’s taking her chances.
Pre-implantation Genetic Diagnosis (PGD) is one of the best procedures to diagnose any sort of genetic defects or chromosomal issues within embryos. Besides sorting the genetic issues, the process further allows you to diagnose and determine the embryo’s quality during its developmental stages. The primary goal is to distinguish those embryos that are reproductively competent and are capable of producing a healthy child from those that cannot. Due to the advancement of medical technology, saviour siblings, as a further use of PGD, transformed from a mere idea to a feasible alternative in 2000 when the first baby, Adam Nash, was engineered or designed to save his older sister from a rare form of anaemia. When Adam was born a stem cell transplantation was done immediately and infused into his sisters Molly’s circulatory system. Molly showed improvement in 4 weeks and in three years her immune system was normal.
The 13-year-old Anna Fitzgerald coined headlines of all kind of newspapers worldwide over the last weeks by suing her parents to fight for her rights. She was genetically created to save her from cancer suffering sister Kate Fitzgerald. Anna endured the pain her whole life that comes with the for Kate life-saving donations. She doesn’t want to aid with this anymore, since the next donation could be life-changing and has fatal potential. That’s why Anna sues her parents in cooperation with the celebrity lawyer Campbell Alexander. In court, they’re fighting for Anna’s right to decide over her own body. In legal terms, this is called medical emancipation.
Anna Fitzgerald is a savior sibling specifically born to aid her sister Kate who suffers from leukaemia. After the young Anna decided to sue her parent over the right to her own body, we decided to speak with the parents of Anna and hear out their opinion.
Yesterday morning I had the chance to ask a few questions to Kate Fitzgerald, who suffers from Leukemia. As the sister of Anna, a savior sibling, she has got some interesting point of views regarding different topics, for instance the relationship with her parents. The following interview will prove that Kate has a breathtaking mindset and a heart of gold.
A savior sibling refers to the creation of a genetically matched human being, in order to be the savior of a sick child in need of a donor. This requires creating human embryos in vitro, which literally means “in glass”, using the egg from the mother and fertilizing the egg with the father’s sperm. Then, using pre-implantation technology, the embryos are tested, and the one who is genetically compatible is implanted into the mother’s womb where the embryo can grow and develop. As soon as that baby is born, the cord blood is often collected because it matches perfectly for the sick sibling. In the embryos further development, bone marrow, blood, or even organs, can also be taken and used for transplantation for the affected sibling. The consequences on the new born and created child are controversial and seen from multiple different perspectives, as the case of the Fitzgerald family shows.
