Predictive, Diagnostic, Prognostic, Oncogenic evidence:
Predictive: The study discusses the efficacy of dabrafenib and trametinib combination therapy specifically in patients with BRAF V600E-mutated anaplastic thyroid cancer, indicating a correlation between the presence of the V600E mutation and the response to this therapy. The mention of a 69% overall response rate further supports the predictive nature of this evidence regarding treatment response.
Diagnostic: The variant BRAF V600E is used to define and classify the specific subtype of anaplastic thyroid cancer being studied, as the therapy was administered to patients with predefined BRAF V600E-mutated malignancies. This indicates that the presence of the V600E mutation is integral to the diagnosis and classification of this cancer type.
Prognostic: The study reports on overall survival and progression-free survival estimates for patients with BRAF V600E-mutated anaplastic thyroid cancer, independent of therapy, suggesting that the presence of this variant may correlate with these disease outcomes. The 12-month estimates of survival rates provide prognostic information related to the variant.
Oncogenic: The BRAF V600E mutation is known to contribute to tumor development and progression, and its presence in anaplastic thyroid cancer suggests an oncogenic role. The study's focus on this specific mutation in the context of a cancer type further supports its classification as oncogenic.
