Do immediate cytology and specialist radiologists improve the adequacy of ultrasound-guided fine-needle aspiration cytology?

Objective: To assess whether a dedicated "1-stop" neck lump clinic has improved the percentage of adequate fine-needle aspiration cytology (FNAC) samples and reduced the need for repeat FNAC.

Study design: Retrospective review.

Setting: District General Hospital in the United Kingdom.

Subjects and methods: Patients attending for ultrasound-guided FNAC over a 6-month period from August 2012 to February 2013. Patients were placed in 4 groups: group 1, FNAC performed by any of the subspecialist radiologists with cytology support (n = 100); group 2, FNAC performed by general radiologists without cytology support (n = 112); group 3, FNAC performed by a particular subspecialist radiologist with cytology support (n = 61); and group 4, FNAC performed by the same subspecialist radiologist without cytology support (n = 125).

Results: There was a significantly higher rate of adequacy of FNAC in the presence of a subspecialist radiologist with immediate cytology (group 1) versus a general radiologist without cytology support (group 2; 87/100 vs 63/112, P = .0001), a significantly higher rate of adequacy of FNAC in the presence of cytology support with the same radiologist (group 3 vs group 4, 55/61 vs 97/125, P = .04), and a significantly higher rate of adequacy of FNAC in the presence of a subspecialist radiologist versus a general radiologist without cytology support (group 4 vs group 2, 97/125 vs 63/112, P = .0005).

Conclusion: Immediate cytology and the presence of a subspecialist radiologist increase the adequacy of FNAC. The adequacy rate of non-cytology-supported FNAC or nonsubspecialist FNAC is below the adequate rate expected from the literature or as recommended in national guidelines.
