혈청 카르시토닌과 CEA 농도는 갑상선 수질암 진단을 받은 환자로 측정되어야 합니다.이 검사는 암이 호르몬을 과분비하는지 평가할 수 있으며, 이 경우는 수술 후 값과 비교되어야 합니다. 수술 후 값은 예후 또는 생화학적 치유(biochemical cure)를 나타냅니다.In a study of 226 patients with MTC (50 percent sporadic MTC, 33 percent multiple endocrine neoplasia [MEN] type 2A [MEN2A], 1 percent MEN type 2B [MEN2B], and 16 percent familial MTC [FMTC]), preoperative serum calcitonin concentrations were significantly correlated with tumor size in both the sporadic and familial cases. In addition, among 45 patients who had a preoperative serum calcitonin concentration of 50 pg/mL or less, 44 had normal concentrations after surgery. In contrast, only 50 of 120 patients with preoperative serum calcitonin concentrations higher than 50 pg/mL had normal concentrations after surgery. In a second study of 224 patients with MTC, 28 of 45 patients (62 percent) wwithoutnodalmetastaseshadnormalcalcitoninpostoperatively、whileonly18of177(10percent)ofnodepositivepatientshadnormal postoperative calcitoninlevels 수술 후 카르시트닌과 CEA 수치가 2배가 되는 시간 평가는 질병의 진행과 전이성 갑상선 수질암의 공격성에 대한 민감한 표시인자입니다.Asan example, postoperative calcitonin doubling time was a prognostic factor for survival in a study of 65patients followed for 3 to 30 years. Ten-year survival was 8,37, and 100percent for doubling times under six months, between survival was, and greater thant for doubling timespector
