Cytogenetics Oncology at Bristol Genetics Laboratory

Bristol Genetics Laboratory (BGL) offers a comprehensive service for cytogenetic testing of oncology samples; primarily for haematological malignancy but also for a range of solid tumour and other referrals.

 

What is Cytogenetics?

 

Cytogenetics is the study of the structure and function of chromosomes. We analyse chromosomes by G-banded metaphase karyotyping, comparing the unique banding pattern of each chromosome pair. Changes in the number or structure of chromosomes can lead to serious problems, such as cancer. A normal cytogenetic result does not exclude the presence of an undetected or cryptic disease related clone.

 

Chromosome analysis is frequently supplemented by:

  • FISH (Fluorescence in situ Hybridisation) 
  • Molecular pathology investigations

 

When do we analyse chromosomes?

 

  • Diagnosis
  • for new patients
  • classification of the disease 
  • Prognosis 
  • diseases where specific disease related chromosome rearrangements are known 
  • for risk stratification
  • Monitoring
  • follow-up studies for cases of relapse
  • where previous cytogenetic abnormalities have been documented
  • transplant and treatment success
  • Patients in clinical trials
