Compared to the group with a single BRAF mutation, the group with combined double/multiple BRAF mutations had a higher recurrence rate (p = 0.019, OR = 10.687, OR (95%CI) = 2.468–46.282), and a higher incidence of thyroid cancer breaking through the thyroid capsule (p < 0.001, OR = 16.562, OR (95%CI) = 4.178–65.662), as shown in Table 6. Here, BRAF is linked to thyroid cancer.
