Abstract

Context.—: Although fine-needle aspiration (FNA) practice by pathologists is now well established, it has been primarily performed by manual palpation. In recent years, pathologists have begun to venture into ultrasound-guided FNAs (UGFNAs). Reports on experiences with this relatively new technique for pathologists have shown promising results. However to date, there have been few studies in the literature comparing pathologist-performed UGFNA with the more traditional pathologist-performed palpation-guided FNA (PGFNA). Objective.—: To compare UGFNA to PGFNA by cytopathologists at an academic medical center. Design.—: A retrospective study of FNAs performed by cytopathologists within the University of California, Los Angeles (UCLA) pathology departmental FNA clinic was performed. Data collected included performance technique (UGFNA versus PGFNA), lesion site and size, adequacy status (nondiagnostic rate), and number of passes per procedure. Corresponding surgical pathology/flow cytometric/cytogenetic result follow-up was compared to FNA results. Findings between UGFNA and PGFNA cases were compared. Results.—: Of 1029 FNA cases during the study period, there were 449 UGFNA cases (43.6%) and 580 PGFNA cases (56.4%). Nondiagnostic rates with UGFNA and PGFNA were 6.7% (30 of 449 cases) and 20.7% (120 of 580 cases), respectively. Nondiagnostic rate was also significantly lower with UGFNA than with PGFNA for lesions within the thyroid (6.0% versus 33.3%), head and neck (6.6% versus 21.2%), and salivary gland (6.2% versus 17.1%), and across all nodule sizes. A total of 495 of 1029 FNA cases (48.1%) had follow-up. Discordance rate was significantly lower with UGFNA than with PGFNA (5.4% versus 12.8%). Conclusions.—: This study shows improved performance characteristics of cytopathologist-performed UGFNA versus PGFNA.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Addition of ultrasound guidance to FNAB allows visualization of targeted lesions and improves accuracy of sample collection by providing information about adjacent anatomy, vascularity, and heterogeneity of lesions.

    “The addition of ultrasound guidance to FNAB not only allows for the visualization of targeted lesions but also improves the accuracy of sample collection by providing information about the adjacent anatomy, vascularity, and heterogeneity of lesions, which helps determine the approach for the biopsy.”
  • When performed specifically by a pathologist, USFNA may yield a higher amount of diagnostic material and lower discordance rates compared to cytopathologist-performed palpation-guided FNAB across various anatomical sites.

    “In addition to the general advantages of ultrasoundguided FNAB (USFNA), studies have indicated that when performed specifically by a pathologist, it may yield a higher amount of diagnostic material and lower discordance rates compared to cytopathologistperformed palpation-guided FNAB across various anatomical sites.46”
  • Ultrasound guidance extends the capability to biopsy deeper lesions that may not be easily palpable, expanding the range of lesions that can be sampled.

    “Ultrasound guidance also extends the capability to biopsy deeper lesions that may not be easily palpable, thereby expanding the range of lesions that can be sampled for diagnostic purposes.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
