Evolving Concepts in Myelodysplastic Syndromes

  • Chapter

Part of the book series: Cancer Treatment and Research ((CTAR,volume 108))

Abstract

Increasingly in the United States, older individuals between 60 to 75 years of age are discovered as having a variable cytopenia, most commonly detected during a routine visit to the doctor. The clinician's instinctive sense that such low-grade abnormalities would passively loiter coupled with limited therapeutic options led to the non-interventional practice of following these patients with no more than periodic blood counts. In the last two decades, this habit has been replaced by bolder attempts at more precise definitions with the result that the vast majority of such individuals are winding up with a diagnosis of Myelodysplastic Syndrome or MDS. The best proof of this statement is provided by the fact that only 143 patients were recorded as having MDS until 1973 ([Saami & Linman, 1973]), while as many as 10,000 cases are being documented annually at the present time in the United States alone. This dramatic increase in incidence is the result of a combination of factors including an increase in the number of older individuals, aggressive attempts towards a specific diagnosis and probably an increase in the actual incidence of MDS due to toxic and chemical exposure. The exigent imperative for an accurate diagnosis comes first and foremost from an appreciation that MDS is not always a harmless pastiche of benign, poorly defined malaise in hematopoietic cells, but rather can be a deadly, exceedingly pernicious disease capable of killing swiftly.
