  • The vast majority of published cytogenetic studies of malignancy have been of leukemias and related hematologic disorders (see Fig. 1), even though these constitute only about 20% of all cancers. It follows that most of what is known about the clinical applications of cytogenetic studies has been derived from hematologic malignancies.

  • Applications of FISH The majority of FISH applications involve hybridization of one or two probes of interest as an adjunctive procedure to conventional chromosomal banding techniques. In this regard, FISH can be utilized to identify specific chromosomes, characterize de novo duplications or deletions, and clarify subtle chromosomal rearrangements. Its greatest utilization, however, is in the detection of microdeletions (see below). Though conventional cytogenetic studies can detect some microdeletions, initial detection and/or confirmation with FISH is essential.

  • The speciality of medical genetics is concerned with the study of human biological variation and its relationship to health and disease. It encompasses mechanisms of inheritance, cytogenetics, molecular genetics and biochemical genetics as well as formal, statistical and population genetics. Clinical genetics is the branch of the specialty involved with the diagnosis and management of genetic disorders affecting individuals and their families.

  • Further development of banding techniques and study of prometaphase chromosomes facilitated better identification of these variations with high resolution. Culturing of free amniocytes was another breakthrough that allowed the identification of chromosomal abnormalities associated with birth defects. These classical cytogenetic techniques became mandatory for several clinical conditions and were adopted by many laboratories as a routine.

  • The relative biological effectiveness of radiations of different quality is examined in detail in this report. The analyses were performed by Scientific Committee 40 of the NCRP which is charged with the responsibility for analysis and evaluation of radiobiological data relevant to radiation protection recommendations. This report is a follow-on to the previous report of Scientific Committee 40 on its evaluation of the effects of dose rate which was published in 1980 as NCRP Report No.

  • Cytogenetic Testing in Prenatal Diagnosis The vast majority of prenatal diagnostic studies are performed to rule out a chromosomal abnormality, but cells may also be propagated for biochemical studies or molecular analyses of DNA. Three procedures are used to obtain samples for prenatal diagnosis: amniocentesis, chorionic villus sampling (CVS), and fetal blood sampling. Amniocentesis is the most common procedure and is routinely performed at 15–17 weeks of gestation.

  • Posttransplantation Treatment BCR/ABL transcript levels have served as early predictors for hematologic relapse following transplantation. These should facilitate risk-adapted approaches with immunosuppression or TK inhibitor(s), or a combination of the two. Donor leukocyte infusions (without any preparative chemotherapy or GVHD prophylaxis) can induce hematologic and cytogenetic remissions in patients with CML who have relapsed after allogeneic SCT.
