Chi Square Analysis

Objective To study the feasibility, safety, and learning curve of ultrasound-guided fine-needle biopsy (USGFNB) performed by a newly trained otolaryngologist in a community office in a setting. Study Design Collect USGFNB data of all thyroid nodules in a prospective manner. Setting A dedicated ultrasound clinic in a large community-based practice, operated by a single surgeon with the purpose of providing office-based point-of-care diagnostic ultrasonography and USGFNB. Subjects and Methods Data on the first 1000 unselected consecutive thyroid nodules that underwent USGFNB over a 3-year period were analyzed. Chi-square analysis was used to assess the statistical significance of characteristics of diagnostic vs nondiagnostic nodules. A multivariate regression analysis was conducted to determine nodule characteristics predictive of adequate sampling. Diagnostic yield and time efficiency data were plotted over a 3-year period to study the learning curve for the USGFNB procedure performed by an operator with no previous experience. Results A total of 1000 nodules in 734 patients including 142 males and 592 females (age range, 17-87 years) were studied. Of the patients, 188 of 734 had more than 1 nodule biopsied, with a maximum of 4 nodules biopsied in 1 setting. The procedure was successfully completed in all patients, with no major complications. A steep learning curve was observed, and adequate samples were obtained in 91.9% of the patients on the first attempt. The cystic nature of the nodule was the biggest predictor of a nondiagnostic yield. Conclusions Otolaryngologist-performed USGFNB of the thyroid is safe, effective, and desirable.

Ancillary Studies

Based on the option that ultrasound-guided core needle biopsy (US-CNB) of the enhanced portion of anterior mediastinal masses (AMMs) identified by contrast-enhanced ultrasound (CEUS) would harvest viable tissue and benefit the histological diagnoses, a retrospective study was performed to elucidate the correlation between the prebiopsy CEUS and diagnostic yield of AMMs and found that CEUS potentially improved the diagnostic yield of AMMs compared with conventional US with a significant increase in the cellularity of samples. Furthermore, the marginal blood flow signals and absence of necrosis can predict the diagnostic yield of AMM. It was concluded that US-CNB of the viable part of AMMs, as verified by CEUS, was able to harvest sufficient tissue with more cellularity that could be used for ancillary studies and improve the diagnostic yield. And CEUS was recommended to those patients with AMMs undergoing repeated US-CNB, with the absence of marginal blood signals or presence of necrosis.

OBJECTIVE Recent articles have identified the poor diagnostic yield of percutaneous needle biopsy for vertebral osteomyelitis. The current study aimed to confirm the higher accuracy of CT-guided spinal biopsy for vertebral neoplasms and to identify which biopsy technique provides the highest yield. METHODS Over a 9-year period, the radiology department at University Hospitals Case Medical Center performed 222 CT-guided biopsies of vertebral lesions, of which clinicians indicated a concern for vertebral neoplasms in 122 patients. A retrospective chart review was performed to confirm the higher sensitivity of the percutaneous intervention for vertebral neoplasms. RESULTS A core sample was obtained for all 122 biopsies of concern (100.0%). Only 6 cases (4.9%) were reported as nondiagnostic per histological sampling, and 12 cases (9.8%) were negative for disease. The question of vertebral neoplastic involvement warrants follow-up, and the current study was able to determine the subsequent diagnosis of each lesion. Of the 122 total, 94 (77.0%) core samples provided true-positive results, and the sensitivity of core biopsy measured 87.9%. The technical approach did not demonstrate any significant difference in diagnostic yield. However, when the vertebral cortex was initially pierced with a coaxial bone biopsy system and subsequently a 14-gauge spring-loaded cutting biopsy needle was coaxially advanced into lytic lesions, 14 true positives were obtained with a corresponding sensitivity of 100.0%. CONCLUSIONS This study confirms the higher sensitivity of image-guided percutaneous needle biopsy for vertebral neoplasms. In addition, it demonstrates how the use of a novel cutting needle biopsy approach, performed coaxially through a core biopsy track, provides the highest yield.
