PROSPECTIVE STUDY TO INVESTIGATE THE USE OF FINE NEEDLE ASPIRATION (FNA) TECHNIQUES IN UK VETERINARY PRACTICE
In our current ageing canine population, neoplasia is increasingly common and affects around 15 in every 1000 dogs annually. Diagnosis of the tumour may be achieved by cytology of fine needle aspirates (FNA) or histopathology of incisional or excisional biopsy samples. FNA is a fast and inexpensive technique which is well tolerated, does not require general anaesthesia and is not associated with significant side effects.
FNA cytology can detect malignancy in approximately two-thirds of malignant tumours and the cellular origin of the lesion can be determined in approximately three-quarters of cases, permitting an early diagnosis and determination of prognosis. Veterinary surgeons are taught to perform FNA as undergraduates, but recommendations regarding technique appear to be extremely variable and no research has been conducted in either veterinary or human medicine to determine the optimal method of acquiring a cell harvest for diagnostic and prognostic purposes. Variations in FNA collection method include differences in needle size, the use and degree of suction applied and details of the slide smearing technique.
Kelly Bowlt, a Clinician in Small Animal Surgery, is investigating FNAs as part of her PhD research. She wishes to determine how commonly FNAs is performed by UK veterinary practitioners and to describe details of methods used by practitioners to collect FNAs.
To help with her study, please complete this questionnaire.
Kelly also plans to conduct a parallel study, measuring cell yields which are achieved with different needle sizes/syringes etc, in order to provide guidelines on the best method for use in practice to optimise collection of a representative and diagnostic cell population.
All completed questionnaires will remain absolutely confidential.
As with all our research at the AHT, we hope our results will directly benefit day to day veterinary work and the welfare of all our patients.
