Has anyone had a fine needle biopsy of a nodule?

Yes: It is a relatively painless technique for diagnosing a nodule. Depending upon the location of the nodule, it is often combined with a radiologic method to confirm correct needle placement, ie, ultrasound, ct. The main drawback is that it only yields cells for evaluation; core needle biopsy will obtain tissue but some nodules are too vascular to permit a core biopsy, ie, thyroid nodules.

A fine needle aspiration (FNA) obtains cellular material for cytologic evaluation. A core needle biopsy (esp. vacuum assisted) obtains pieces of tissue for histologic evaluation.

Benign or malignant: An fna of a thyroid nodule can tell with great accuracy whether the nodule is cancerous and what type of cancer it is.

Very Accurate: An article from baylor in 2000 looked at more than 6000 patients who underwent thyroid fna biopsy. Sensitivity and specificity values of thyroid fna were 93% and 96%. The current nci classification: 1) nondiagnostic fna samples, 2) benign lesions, 3) malignant lesions, 4 atypia/follicular lesion of undetermined significance, 5) suspicious for a follicular lesion. Most common result benign.
