Our patient was advised to undergo radioactive iodine therapy after our institute's multidisciplinary tumor board consensus. She completed her first postoperative follow-up at one month, during which serum calcitonin and carcinoembryonic antigen (CEA) levels were within normal limits, and the unstimulated serum thyroglobulin (Tg) was less than 0.2 ng/mL (Table 3). The gene discussed is CALCA; the disease is neoplasm.
