Objective:
To improve recognition of thyroid carcinoma in rapid consultation on Diff-Quik-stained (Fisher Diagnostics, Middletown, Virginia, USA.) fine-needle aspiration (FNA) and rapid hematoxylin-eosin (H-E)-stained intraoperative scrape preparation (ISP) specimens by assessing 3 variables (anisokaryosis, nuclear overlap [NO] and scant/absent colloid) in cases of cellular follicular lesions (CFL), an indeterminate diagnostic category.
Study Design:
Thirty-seven FNAs and 28 ISPs diagnosed as CFL, with histologic follow-up, were evaluated in blinded fashion by 3 cytopathologists assessing the 3 variables.
Results:
Over 90% of the malignant cases showed NO in both FNA and ISP, while only 22% of the benign cases did; positive and negative predictive values (PPV and NPV) were 82% and 100%. All malignant cases showed significant anisokaryosis in both FNA and ISP in contrast to 24% of benign cases; PPV and NPV were 74% and 100%. Scant/absent colloid was seen in 87% and 39% of malignancies in FNA and ISP, respectively, as compared to 55% and 20% of the benign cases. PPV and NPV were 52% and 83% in FNA and 63% and 60% in ISP, respectively.
Conclusion:
Application of these variables improves recognition of thyroid carcinoma, particularly in fine needle aspirates, while additional material may be requested. With ISP, their absence supports recommending against further surgery. Together, optimal surgical planning and outcome may be obtained.
