A thyroid cancer previously known as “encapsulated follicular variant of papillary thyroid carcinoma” is no longer classified as a cancer at all. It is now known as “noninvasive follicular thyroid neoplasm with papillary-like nuclear features”, or NIFTP for short.
This type of lesion is diagnosed through a thyroid lobectomy. Historically, the treatment would have been a completion thyroidectomy followed by radioactive iodine, but in studies of large volumes of patients, it turns out that additional treatment for these types of lesions is unnecessary.
Moving forward, patients previously diagnosed with these lesions no longer need routine cancer follow-up visits or scans, and patients who are diagnosed with these lesions do not get additional surgery or radioactive iodine indicated for cancerous lesions.
