WebThis FISH test detects an abnormal clone in approximately 70% of patients with indolent disease and in greater than 80% of patients who require treatment. At least 5% of patients referred for CLL FISH testing have translocations involving the IGH locus. WebIntroduction. Cancers develop and progress because of genetic instability and the accumulation of mutations. A high frequency of chromosomal aberrations in human peripheral blood lymphocytes (HPBL) has been shown to be a risk factor for the cancer initiation process. 1,2 The frequency of chromosome aberrations increases with radiation …
