ABSTRACT
Objective:
To investigate the efficacy and safety of anlotinib in distant metastatic radioactive iodine-refractory differentiated thyroid cancer (RAIR-DTC).Methods:
Retrospective analysis was performed on 17 patients with distant metastatic RAIR-DTC (6 males, 11 females, age 57.0(45.5, 63.0) years) from Affiliated Hospital of Qingdao University between October 2018 and February 2023, including 13 patients receiving first-line treatment and 4 patients receiving second-line treatment with anlotinib. The changes of serum thyroglobulin (Tg) during the treatment of anlotinib, the changes of maximum diameter of the target lesion at the last follow-up compared with the diameter at baseline, the imaging efficacy, and treatment-related adverse events were analyzed. The serological and imaging effects of the first-line treatment group and the second-line treatment group were compared. The Fisher exact test was used to analyze the differences between groups.Results:
The follow-up time of 17 patients was 17.3(9.5, 21.4) months, and the objective response rate (ORR) and disease control rate (DCR) were 7/17 and 16/17, respectively. There were no significant differences of ORR (6/13 vs 1/4; P=0.603) and DCR (13/13 vs 3/4; P=0.235) between the first-line and second-line treatment groups. The change rates of serum Tg at 3, 6 weeks and the last follow-up were -30.2%(-61.2%, -15.5%), -64.8%(-90.6%, -32.3%), and -85.8%(-96.1%, -50.7%), respectively. At the last follow-up, the change rate of maximum diameter of target lesions was -20.0%(-45.0%, -5.2%). The incidence of treatment-related adverse reactions was 14/17, and 2 patients (2/17) had grade 3 or above adverse reactions.Conclusion:
Anlotinib shows superior efficacy with tolerable toxicity in the first-line treatment of distant metastatic RAIR-DTC, and hopefully plays an important role in second-line treatment for RAIR-DTC resistant to sorafenib.
