Braf Mutation Thyroid Cancer, Oct 14, 2024 · Activating mutations in the BRAF oncogene occur in 45% of papillary thyroid carcinomas (PTCs). We conducted a retrospective analysis of 1160 PTC patients treated with RAI therapy. Previously, D+T showed clinically meaningful results in patients (pts) with BRAF V600E mutation–positive DTC, anaplastic thyroid cancer, non–small cell lung cancer, melanoma, and pediatric glioma. Dec 18, 2025 · The incidence of thyroid cancer has increased worldwide over last few decades and it accounts for the most common endocrine tumor. This increased incidence of thyroid cancer is attributed to radiological detection of small thyroid lesions. Moreover, BRAF mutations can predict response to targeted therapies, such as BRAF inhibitors. DICER1 mutations are associated with patients’ age and the size of thyroid nodules. 6 days ago · A Randomized Phase III Study of BRAF-Targeted Therapy vs Cabozantinib in RAI-Refractory Differentiated Thyroid Cancer with BRAF V600E By Lova Sun, MD, MSCE @LovaSunMD Supporting: 23, Contrasting: 1, Mentioning: 272 - Thyroid cancer poses a significant clinical challenge, and our understanding of its pathogenesis is incomplete. The effect of BRAFV600E mutation on PTC-associated LN metastasis has not been clearly established. BRAF V600E and telomerase reverse transcriptase (TERT) promoter mutations synergistically drive recurrence and mortality in papillary thyroid cancer. BRAF encodes a serine/threonine protein kinase downstream of the epidermal growth factor receptor (EGFR) and the RAS family of small G-proteins (KRAS, HRAS and NRAS) in the MAPK pathway. Gemcitabine Recruiting Phase 1 Trials for Solid Tumors / KRAS G12R / Thyroid Neoplasm / Brain Neoplasm / KRAS G12F / BRAF / BRAF V600 mutation / BRAF Gene Mutation / KRAS G13C / Thyroid Cancer / KRAS G12A / Thyroid Carcinoma / Acquired Resistance to KRAS G12C Inhibitor / Refractory Histiocytic and Dendritic Cell Neoplasm / Histiocytic Neoplasms 3 days ago · This study aimed to evaluate the predictive role of peripheral blood lymphocyte subsets in therapeutic efficacy for papillary thyroid cancer (PTC) patients BRAF Ventana VE1 IHC assay revealed strong expression in BRAF mutation positive patients and no expression in BRAF mutation negative patients in colorectal carcinoma (A–D), papillary thyroid carcinoma (E–H) and melanoma (I–L), respectively. Summary Papillary thyroid cancer (PTC) is the most common well-differentiated thyroid cancer. See test Thyroid cancer is the most common endocrine malignancy, with rising resistance to radioactive iodine therapy in differentiated thyroid cancer (DTC). BRAF is mutated in a variety of human tumors, most frequently in melanoma and in papillary thyroid cancer. Genetic mutation of BRAF V600E usually hint poor prognosis for PTC, and the research of BRAF V600E is mature in colorectal cancer, thyroid cancer and melanoma, and BRAF mutation is very significant for proliferation, invasion and metastasis of these tumors. Sep 24, 2025 · To evaluate whether BRAF V600E mutation status enhances the value of age in predicting clinical outcomes for papillary thyroid carcinoma (PTC) patients receiving radioactive iodide (RAI) therapy. The thyroid mutation panel assesses for all 8 of the most common mutations or rearrangements associated with thyroid neoplasia. BRAF V600E mutation–positive DTC is a prevalent malignant tumor of the endocrine system in the CMS population. Dabrafenib Active Not Recruiting Phase 2 Trials for BRAF Gene Mutation / Anaplastic Thyroid Cancer / Thyroid Cancer / Anaplastic Thyroid Carcinoma / B-Raf Mutation-Related Tumors / Thyroid Neoplasm Treatment BRAF V600E mutation–positive DTC is a prevalent malignant tumor of the endocrine system in the CMS population. The BRAF codon 600 mutation, and RET/PTC1 and RET/PTC3 rearrangements are highly associated with papillary thyroid cancer, the PAX8-PPAR {gamma} with follicular carcinomas and RAS mutations (in either HRAS, KRAS and NRAS) usually with follicular neoplasms. Lymph node (LN) metastasis is frequently seen in PTC. Jul 3, 2025 · DICER1-mutant nodules are unlikely to be BRAF-mutant thyroid carcinomas. Objective: BRAF V600E mutation is the most common and clinically significant genetic alteration in advanced thyroid cancers. A greater percentage of BRAF V600E patients had higher stages of cancer, suggesting a faster and more aggressive growth pattern compared to the mutation negative patients. BRAF V600E-driven tumors exhibit high Extracellular signal-regulated kinase phosphorylation, leading to unregulated cell proliferation and inhibition of the required genes for radioiodine responsiveness in thyroid cancer. Targeted therapy may be a part of the treatment for thyroid cancers with BRAF mutations. Despite the unfavorable course associated with PTCs harboring BRAF V600E mutation, its prognostic role remains debated. Gemcitabine Recruiting Phase 1 Trials for Carcinoma / Solid Tumors / KRAS G12R / Thyroid Neoplasm / Brain Neoplasm / KRAS G12F / BRAF / BRAF V600 mutation / BRAF Gene Mutation / KRAS G13C / Thyroid Cancer / KRAS G12A / Clear Cell Renal Cell Carcinoma / Thyroid Carcinoma / Acquired Resistance to KRAS G12C Inhibitor / Refractory Histiocytic and Classical point mutations of RET, BRAF and RAS oncogenes are not shared in papillary and medullary thyroid cancer occurring simultaneously in the same gland The BRAF Genetic Alteration Cell Panel (ATCC TCP-1032) is composed of eight selected human tumor cell lines from various common cancer types that carry BRAF hotspot mutations in codon 600. BRAF mutations are also found in lower frequency in colorectal cancer, non-small cell lung cancer For example, Quest Diagnostics offers a Thyroid Cancer Mutation Panel, which includes BRAF and RAS variant analysis and testing for RET/PTC and PAX8/PPAR rearrangements. Recent findings: Despite the unfavorable course associated with PTCs harboring BRAF V600E mutation, its prognostic role remains debated. A bioinformatics assessment was conducted using the COSMIC database and in silico data analysis. Prescribed by, or in consultation with an oncologist; AND Dabrafenib (Tafinlar) will be used in combination with trametinib (Mekinist), but will not be used with any other oncolytic medication; AND Diagnosis of anaplastic thyroid cancer; AND Both of the following are met: Jun 19, 2025 · BRAF mutations can be used as diagnostic biomarkers to identify patients with specific cancer types, such as melanoma and thyroid cancer. Though less studied, K601E may identify a clinically distinct subset of thyroid neoplasms. The BRAF mutation status of each cell line has been sequenced and validated by ATCC. In the last decade, there has been an unprecedented advancement in the molecular information of thyroid neo-plasms, which has revolutionized the Some types of thyroid cancers have mutations in the gene coding for the BRAF protein. Jan 1, 2022 · The aim of this review is to discuss the impact of BRAF mutations on clinical features and treatment of patients with thyroid cancer. To gain insight into the pathogenesis of papillary thyroid carcinoma, transcriptional profiles of four normal thyroids and 51 papillary carcinomas (PCs) were generated using DNA microarrays. This study provides real-world experience with BRAF and MEK inhibitors other than dabrafenib and trametinib in the treatment of advanced thyroid cancers harboring this mutation.
