microRNA (miRNA) Profiling Differentiates Noninvasive Follicular Thyroid Neoplasm with Papillary-like Nuclear Features (NIFTP) from Invasive Encapsulated Follicular Variant of PTC (iEFVPTC)

ATA 2018 Washington DC

Follicular patterned thyroid neoplasms with papillary carcinoma nuclear features, with or without invasion, are increasingly recognized as a diverse group of neoplastic processes.

NIFTP is unlikely to undergo metastatic spread and thus treated by lobectomy
iEFVPTC, reflecting neoplastic progression with microscopic evidence of capsular invasion, is regarded as malignant

Mutational findings between these two closely related states does not discriminate between them.
Using well-characterized cohorts of these two entities, we show in microdissected tissue that microRNA (miRNA) profiling can effectively differentiate these entities.

Patient management decisions are based on the independent medical judgment of the physician and molecular test results should be taken into consideration in conjunction with all relevant imaging, clinical findings, patient and family history, as well as patient preference.
