甲状腺未分化癌の1例—非伸展例の取り扱いについて

Giant Anaplastic Carcinoma of the Thyroid:A Case Report

　はじめに

　甲状腺未分化癌の予後は極めて悪く，全悪性腫瘍の中でも最悪とされている^1）。腫瘍の発育が極めて速いため診断確定に手間取ると，初診時に手術可能と考えられた症例でも手術不能となることも多い。

　今回われわれは，生検後5日で手術を行い，術後に外照射，化学療法を追加し良好な経過をたどった例を経験したので報告する。

A 71-year-old man with anaplastic carcinoma of the thyroid was complaining of a swelling of his neck. MRI and CT revealed a tumor pressing thetrachea and the larynx. An open biopsy was per-formed and pathological diagnosis was anaplastic carcinoma of the thyroid. Left thyroidectomy and modified neck dissection were performed. After the operation, radiotherapy (40 Gy) and combined chemotherapy (EAP) were done. Multimodal ther-apy including tumor resection was effective in this case. The patient's general condition has remained satisfactory for one year.
