Thyroid cancer diagnosis with transdermal probe 22G U/S versus EBUS-convex probe TBNA-B 22G and 19G: pros and cons

ABSTRACT

Introduction

Thyroid cancer is usually diagnosed both with imaging techniques and transdermal biopsy. Laboratory tests are also included in the initial work-up.

Patients and Methods

One hundred and thirty patients were included in our study with pathological imaging findings in the thyroid region. Biopsies were performed with 22 G with transdermal convex probe, EBUS 22 G Mediglobe® needle and 19 G Olympus® needle. We investigated the efficiency and safety of both techniques and identified the best candidates for each method.

Discussion

19 G needle identified cancer types such as; Lymphoma, Medullary thyroid cancer, and Hurthle cell cancer, which we know from previous pathology studies that a larger sample is necessary for diagnosis. No safety issues were observed for both techniques and the EBUS technique produced more cell block material when 22 G needle was compared to transdermal biopsy in peritracheal lesions.

Conclusion

The method of biopsy should be made based on the size and accessibility of the lesion.
