Evaluation of anaplastic thyroid carcinoma in the Kurdistan region of Iraq

Background Anaplastic thyroid carcinoma is a rare and lethal disease that accounts for 1-2% of thyroid malignancies. It is an aggressive locoregional disease with a high rate of distant metastasis, a poor prognosis, and a mean survival rate of 3-6 months after diagnosis. This retrospective study aimed to analyse the clinical and pathological features of ATC to assess treatment procedures and its outcome. Methods We analysed data from 22 patients diagnosed with ATC from 2018 to 2021, using the Kaplan-Meier method and log-rank test to determine overall survival. Results Patients' median age was 64.3 +/- 17.1 years. Females were more affected (male/female ratio: 1:1.7); 14 cases occurred in females (63.6.4%), and eight in males (36.4%). The most common manifestations were neck enlargement (81.8%) and dyspnoea (72.27%), and the tumour size was > 4 cm in 17 (77.3%) patients. The percentage of cases that presented in clinical-stage IVA was 36.4%, with 31.8% presenting in clinical-stage IVB and 31.8% presenting in clinical-stage VIB. Among 22 cases, 14 (63.6%) were operable, and 8 (36.4) were inoperable (p = 0.015). Multimodal therapies were associated with better survival (surgery plus radiotherapy without systemic treatment, P = 0.063). The median overall survival was three months (IC 95%, 0.078-5.922). One-year and two-year survival rates were 9% and 4.5%, respectively. Conclusion ATC is a rapidly growing cancer that, fortunately, is rare. Early diagnosis and multimodality treatment may provide a better quality of life and survival time for this group of patients.
