NCOA4::RET rearrangements were statistically significantly associated with the tall cell subtype (p = 0.019) and angioinvasion (p = 0.001), lymphatic invasion (p = 0.003), lymph node metastasis (p= <0.001), extrathyroidal extension (p = 0.001) and extranodal extension (p = 0.013). The gene discussed is RET; the disease is metastatic malignant neoplasm in the lymph nodes.
