Treatment

  • Treatment Treatment for acute erythroblastic leukemia depends on the features of the cancer cells present and on the extent of the disease, as well as on the age of the patient, his symptoms, and general health condition.[encyclopedia.com]
  • Treatment The treatment for this type of leukemia would largely depend of the cancer cell features presented as well as the extent or severity of the disease, the patient's age, symptoms along with general health condition.[medigest.uk]
  • Medical professionals think that prolonged exposure to ionizing radiation or previous chemotherapy treatments can increase a patient’s risk of contracting erythroleukemia.[knowcancer.com]
  • Treatment . The treatment of choice is systemic combination chemotherapy with a variety of antineoplastic drug regimens. The disease can also be treated by a bone marrow transplant after a remission is achieved with chemotherapy. Patient Care .[medical-dictionary.thefreedictionary.com]
  • Utilize new, clinically important molecular genetic data and updated classification schemes to help guide treatment and targeted therapy.[books.google.com]

Prognosis

  • Although der(1;7) has been reported as a cytogenetic factor for poor prognosis in t-MDS/AML, our patient showed a good response to chemotherapy and obtained complete remission, although longer observation is required to evaluate the prognosis.[ncbi.nlm.nih.gov]
  • Of note was the finding that the percentage of myeloblasts, which may account for only a small fraction of the total marrow elements when the revised FAB criteria are applied, had no bearing on prognosis.[ncbi.nlm.nih.gov]
  • Staging, Diagnosis, Prognosis, and summaries of Pitfalls in working with these pathologies are presented along with ample figures.[books.google.com]
  • Prognosis The prognosis for patients with erythroleukemia is typically poor—on average, the patient is given a 6-month survival period.[knowcancer.com]

Etiology

  • Etiology Genetic and chromosomal aberrations, such as are found in other leukemias, are characteristic.[medical-dictionary.thefreedictionary.com]
  • They are organised into groups, and further divided into clinical, etiological or histopathological sub-types.[orpha.net]
  • The etiology of erythroleukemia remains elusive, but the likelihood that it develops secondary to chemotherapeutic treatment or exposure to mutagenic agents is significant.[academic.oup.com]
  • However, these abnormalities are not specific for erythroleukemia and can present in other dyserythropoiesis etiologies such as myelodysplastic syndrome. The bone marrow is usually hypercellular and shows major dysplasia in the red cells.[hematologyandoncology.net]

Prevention

  • Prevention Since this form of cancer is very rare and its causes are largely unknown, no specific preventive measures can be recommended.[encyclopedia.com]
  • […] national prevention strategies.[ceub.it]
  • They eventually crowd out normal, healthy blood cells and prevent them from being produced. AML can accumulate in the blood stream and organs such as the lymph nodes, brain, liver, kidneys, ovaries, testicles, and skin.[seattlecca.org]

  • Therefore, the p53 pathway may play an important role in the erythroid lineage, improving the efficiency of erythropoiesis and preventing malignant transformation [ 14 , 15 ].[hoajonline.com]
