Systematic review and meta-analysis of the efficacy of dabrafenib and trametinib in the multi-modal treatment of anaplastic thyroid cancer
Published online by Cambridge University Press: 11 December 2024
Abstract
This study analyses the current literature to evaluate the effectiveness of dabrafenib and trametinib in the multi-modal treatment of anaplastic thyroid cancer (ATC).
A systematic review and meta-analysis of the literature were undertaken. The primary endpoint measured was overall response rate (ORR) defined by the RECIST v1.1 guidelines. Secondary endpoints were 12-month overall survival (OS), median OS and progression-free survival (PFS).
Of 656 identified reports, 8 studies were included which featured 95 patients (median age 68.5 years, 46 per cent male). Median follow-up period was 11.8 months with a 12-month OS of 51 per cent. Median OS was 10.4 months. Progression-free survival (PFS) was 6.5 months. The ORR was 71 per cent. A total of 65 patients exhibited a partial or complete response in radiological tumour size. Side effects compared favourably to other kinase inhibitors.
Dabrafenib and trametinib exhibit a promising tumour response with a tolerable side profile. BRAF/MEK inhibitors continue to provide robust responses in BRAF-mutated ATC. The heterogeneity and lack of controls in included studies limits the confidence in the conclusions drawn.
