Objective: To evaluate the association between BRAF(V) 600E mutation and pathological features in papillary thyroid carcinoma (PTC).
Methods: The raleted studies were searched through Medline, PubMed, and Web of Science, and meta-analysis was used to calculate the OR and 95%CI of the study results.
Results: A total of 52 studies including 12 029 PTC patients was identified. The prevalence of BRAF(V) 600E mutation in PTC was 57.85%. There was a closed association between the BRAF(V) 600E mutation and pathological features, including advanced TNM stage (OR = 1.89, 95%CI 1.58-2.27), lymph node metastasis (OR = 1.74, 95%CI 1.42-2.14), multifocality (OR = 1.25, 95%CI 1.07-1.46), and recurrence (OR = 2.26, 95%CI 1.25-4.09) of PTC. For Asians with PTC, the association between the BRAF(V) 600E mutation and pathological features was indicated for advanced TNM stage (OR = 1.56, 95%CI 1.24-1.96) and lymph node metastasis (OR = 1.57, 95%CI 1.25-1.99). For Europeans with PTC, the association between the BRAF(V) 600E mutation and pathological features was indicated for advanced TNM stage (OR = 2.63, 95%CI 2.10-3.30), lymph node metastasis(OR = 1.97, 95%CI 1.19-3.25), and multifocality (OR = 1.35, 95%CI 1.01-1.80).
Conclusion: There were associations between the BRAF(V) 600E utation and advanced TNM stage, lymph node metastasis, multifocality, and recurrence of PTC.

Papillary microcarcinomas (PMCs) are papillary carcinomas ≤1 cm in size, with an increasing incidence. Although generally indolent, some cases exhibit aggressive behavior. Recently, active surveillance has been recommended to avoid surgical treatment.

Introduction: One of the most robust global challenges and difficulties in the 21st century is cancer. Treating cancer is a goal which continues to motivate researchers to innovate in design and development of new treatments to help battle the disease.
Objectives: Our objective was developing new antiapoptotic hybrids based on biologically active heterocyclic motifs "benzimidazole?oxadiazole-chalcone hybrids'' that had shown promising ability to inhibit EGFR and induce apoptosis.
Ovarian serous borderline tumors (SBTs) harboring the BRAFV600E mutation are associated with decreased risk of progression to low-grade serous carcinoma, and often prominently feature tumor cells with abundant eosinophilic cytoplasm. Since eosinophilic cells (ECs) may be a marker of the underlying genetic driver, we proposed morphologic criteria and evaluated the interobserver reproducibility for assessing this histologic feature. Following the completion of an online training module, representative tumor slides from 40 SBTs ( BRAFV600E -mutated, n=18, BRAF -wildtype, n=22) were independently reviewed by 5 pathologists.

Papillary thyroid carcinoma (PTC) is the most common malignancy of the thyroid gland and early stages are curable. However, a subset of PTCs shows an unusually aggressive phenotype with extensive lymph node metastasis and higher incidence of locoregional recurrence. In this study, we investigated a large cohort of PTC cases with an unusual aggressive phenotype using a high-throughput RNA sequencing (RNA-Seq) to identify differentially regulated genes associated with metastatic PTC.
