Anaplastic Thyroid Carcinoma Research Consortium of Japan (ATCCJ) was established in 2009 aiming to a) accumulate clinical data of ATC nationwide and to form authentic large database, b) conduct nationwide clinical trials, c) collaborate with basic scientists. The precise clinical data, including the therapeutic methods and outcome, of over 1,000 cases from 55 institutes had been accumulated in January 2015 to form the world largest database of ATC.
By analyzing the data, the 6 months disease specific survival was calculated as 60, 45, and 19% in stage IVA, B, and C disease, respectively. Age over 70, acute symptoms, leukocytosis, and tumor diameter over 5 cm, extrathyroidal invasion, and distant metastasis were revealed to be significantly poorer prognostic factors [1]. Survival after surgery was significantly better when curative resection was accomplished [2], or when the disease was observed incidentally during pathological examination after surgery [3]. Extra-beam radiation therapy contributed longer survival. At the same time we found that there were considerable numbers of cases misdiagnosed and treated as ATC. Those cases commonly survived long after treatments [4]. The information should be important for conducting therapeutic strategy. Still, the meaning of chemotherapy was controversial. Therefore, a nationwide prospective clinical study to evaluate the feasibility of weekly paclitaxel administration was conducted [5]. The entrée ended on March 2014, and the data was presented in ITC 2015 at Orlando [6].
We are planning for new clinical trials, and for establishing tissue bank at this moment.
