Our Answer

We have identified the following information that we hope you find helpful. If you still have questions, please contact us.

What causes myelodysplastic/myeloproliferative disease?

In most cases, the cause of myelodysplastic/myeloproliferative disease is unknown, and there is limited information regarding potential causes. No specific genetic defects have been identified for any of the diseases. The specific cause of chronic myelomonocytic leukemia (CMML) is unknown, but exposure to occupational and environmental carcinogens (agents that can cause cancer), ionizing radiation, and cytotoxic agents (agents that are toxic to cells) have been associated in some cases. The cause of juvenile myelomonocytic leukemia (JMML) is not known; however, children with neurofibromatosis type 1 (NF1) are at increased risk for developing JMML, and up to 14% of cases of JMML occur in children with NF1. Atypical chronic myelogenous leukemia (aCML) has been associated with cytogenetic (chromosomal) abnormalities in as many as 80% of individuals with the disease; however, no cytogenetic abnormality is specific. Myelodysplastic/myeloproliferative neoplasm, unclassifiable (MDS/ MPN-UC) (also known as mixed myeloproliferative/ myelodysplastic syndrome) also has no known cause.[1]

Are there any current research studies regarding myelodysplastic/myeloproliferative disease?

The U.S. National Institutes of Health, through the National Library of Medicine, developed ClinicalTrials.gov to provide patients, family members, and members of the public with current information on clinical research studies. To find these trials, click on the link above and use "myelodysplastic/myeloproliferative" as your search term. After you click on a study, review its "eligibility" criteria to determine its appropriateness. Use the study’s contact information to learn more. Check this site often for regular updates.

You can also find relevant articles on myelodysplastic/myeloproliferative disease through PubMed, a searchable database of biomedical journal articles. Although not all of the articles are available for free online, most articles listed in PubMed have a summary available. To obtain the full article, contact a medical/university library or your local library for interlibrary loan. You can also order articles online through the publisher’s Web site. Using "myelodysplastic/myeloproliferative" as your search term (or one of the individual diseases) should help to locate articles. Use the "advanced" or "limits" feature to narrow your search results. Click here to view a search.

The National Library of Medicine (NLM) Web site has a page for locating libraries in your area that can provide direct access to these journals (print or online). The Web page also describes how you can get these articles through interlibrary loan and Loansome Doc (an NLM document-ordering service). You can access this page at the following link http://nnlm.gov/members/. You can also contact the NLM toll-free at 888-346-3656 to locate libraries in your area.
