유두상 갑상선암의 대부분은 서서히 진행하는 양호한 임상경과를 보이나, 일부는 저등급 혹은 미분화 갑상선암으로 전환되는 생물학적 특성을 보인다. 저자는 유두상 갑상선암 환자 358예를 적용된 치료방법과 치료결과를 분석하여 논란이 되고 있는 치료방법들 중에서 적절한 치료방법을 찾고자 본 연구를 시도하였다.% 568예중 동측엽절제술 및 협부 절제술 혹은 갑상선 아전 절제술 220예, 갑상선 전 절제술 혹은 근전절제술 143예, 종양적출술 5예였고, 이중 115예는 여러가지 형태의 경부 곽청술이 추가되었고, 150예는 수술후 방사성 동위원소 치료까지 추가되었다. 또 전 환자에서 TSH 억제를 위한 갑상선 호르몬 투여를 하였다. 추적 기간은 5년에서 12년까지 평균 8.5년이었다. Cady와 Rossia AMES Scoring system에 따라 저위험군과 고위험군으로 나누어 재발율과 사망율을 산출한 결과 저위험군 255예중 재발율 11.0%, 사망율 0.4%, 고위험군 65예중 재발율 36.9%, 사망율 20.0%을 보여 고위험군에서 현격히 불량한 예후를 나타내었다. 따라서 저자들은 유두상 갑상선암의 치료방법 선택은 일률적인 치료방법 보다는 환자 개인의 임상적 특성, 병기 등을 고려하여 저위험군에서는 소극적 수술을, 고위험군에서는 적극적인 수술과 수술후 보조치료를 시행하는 것이 바람직하다고 사료되었다.

Objectives: Three classic treatment modalities have been used to treat Graves' disease: antithyroid medication, radioiodine ablation, and subtotal thyroidectomy. Postoperative thyroid functions were studied in patients with Graves' disease treated by subtotal thyroidectomy to evaluate the superiority of surgical treatment. Materials and Methods: One hundred fourty patients of Graves' disease were analysed retrospectively in follow-up for more than three years following subtotal thyroidectomy. Postoperative serum levels of $T_3,\;T_4, TSH, TSH-R Ab, free $T_4$, were evaluated to watch hypo- or hyperthyroidsm. Results: In the evaluation of preop- and postoperative thyroid function after three years of subtotal thyroidectomy, $T_3$ was changed from $464.10{\pm}196.16ng/dl$ to $140.41{\pm}76.56ng/dl$ in mean value, $T_4$ was changed from $20.76{\pm}7.98{\mu}g/dl$ to $9.54{\pm}4.02{\mu}g/dl$, $TSHT_3$ was changed from $0.55{\pm}4.42{\mu}u/ml$ to $4.96{\pm}7.20{\mu}u/ml$, TSH-R Ab was changed from $41.6{\pm}28.27%$ to $28.7{\pm}28.79%$ and free $T_4$ was changed from $4.45{\pm}2.33ng/dl$ to $1.44{\pm}0.69ng/dl$ in mean value. Euthyroidism was noted in 118 patients(84.3%), overt hyperthyroidism in 6 patiens(4.3%), latent hyperthyroidism in 8 patients(5.7%), overt hypothyroidism in 2 patint(1.4%), and latent hypothyroidism in 6 patients(4.3%). Of surgical complications, permanant hypoparathyroidism was found in one patient, recurrent laryngeal nerve injury in two patients, postoprative bleeding with reoperation in two patients, and death in one patient. Conclusion: The thyroid function after subtotal thyroidectomy in diffuse toxic goiter is normal level (euthyroidism) in 84.3% and low recurrence rate of hyperthyroidism is showed with rare surgical complication. Therefore, subtotal thyroidectomy in diffuse toxic goiter is more effective and safe than RI or longterm ATD treatment, if the operation is performed by skillful surgeon.
