Objective: The aim of the work described here was to explore the predictive value of multimodal ultrasound combined with the BRAF gene in cervical lymph node metastasis (CLNM) of papillary thyroid microcarcinoma (PTMC).
Methods: One hundred six patients (114 lesions) with PTMC confirmed by surgery and pathology at Yantai Yuhuangding Hospital from July 2021 to August 2022 were analyzed retrospectively. Routine ultrasound, contrast-enhanced ultrasound, shear wave elastography examination and BRAF V600E gene detection were performed before surgery. Patients were divided into two groups on the basis of post-operative pathology: non-metastasis group and metastasis group. Univariate and multivariate analyses were used to analyze the risk factors of cervical lymph node metastasis in PTMC.
Results: Univariate analysis revealed that there were significant differences in gender, high echo in lesions, enhancement level, peak intensity (PI) and average modulus of elasticity (E) between the two groups (p < 0.05), but there was no significant difference in BRAF gene mutation (p = 0.855). Multivariate analysis revealed that male gender, microcalcification and hyper- or iso-enhancing parametric increased the risk of CLNM in PTMC (p < 0.05), and that sensitivity (92.3%) and accuracy (73.9%) were higher for combined diagnosis than for single diagnosis; the differences were statistically significant (p < 0.05).
Conclusion: Male gender, microcalcification and hyper- or iso-enhancing parametrics of CEUS are independent risk factors for CLNM in PTMC patients. Combined diagnosis is more effective.

Introduction: BRAFV600E mutation (BRAF) is common in papillary thyroid cancer (PTC), and most patients have an excellent outcome. However, a TERT-promoter mutation (pTERT) in the presence of BRAF (BRAFpTERT) has been demonstrated to confer a more aggressive behavior to PTC. Lymphocytic infiltration is often present in PTC.

Pilocytic astrocytomas (PAs) are benign grade 1 gliomas according to the World Health Organization (WHO). They are common in children but rare in adults in whom they may have a worse prognosis. Pediatric PAs are usually associated with dysregulation of the mitogen-activated protein kinase (MAPK) pathway, often involving BRAF alterations such as the KIAA1549::BRAF (K-B) fusion or V600E mutation.

Background: Oligo-metastatic disease (OMD) in colon cancer patients exhibits distinct clinical behavior compared to poly-metastatic disease (PMD), with a more responsive and indolent course. This study aims to identify clinical and biological factors uniquely associated with oligo-metastatic behavior.
Methods: Metastatic colon cancer patients from an academic center underwent genetic characterization.

Isolated gastric Langerhans cell histiocytosis (LCH) occurs extremely rarely in adults. We characterized the clinicopathological and molecular genetics of this rare entity. We retrospectively analyzed the clinicopathologic and prognostic features of 3 patients with isolated gastric LCH during the past 10 years, with a review of an additional 20 patients from the literature.

Background: Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, accounting for about 85% of all lung cancer cases. While some cases of NSCLC with actionable genomic alterations in the tumour cells may respond to standard therapies, they often show greater improvement with targeted therapies. The current standard of care in Ontario involves testing for actionable genomic alterations using both DNA and RNA panels via tissue testing alone.
