Background: Papillary thyroid cancer (PTC) is the most common epithelial thyroid tumor, accounting for more than 80% of all thyroid cancers. Though the fine needle aspiration biopsy (FNAB) represents as the golden standard for the diagnostics of thyroid nodules, there is a ∼25% risk of indeterminate cytological features. TMPRSS4 is a newly found transmembrane serine protease which was overexpressed in papillary thyroid cancer (PTC). Read More

Purpose: The second International Consensus Conference on B3 lesions was held in Zurich, Switzerland, in March 2018, organized by the International Breast Ultrasound School to re-evaluate the consensus recommendations.
Methods: This study (1) evaluated how management recommendations of the first Zurich Consensus Conference of 2016 on B3 lesions had influenced daily practice and (2) reviewed current literature towards recommendations to biopsy.
Results: In 2018, the consensus recommendations for management of B3 lesions remained almost unchanged: For flat epithelial atypia (FEA), classical lobular neoplasia (LN), papillary lesions (PL) and radial scars (RS) diagnosed on core-needle biopsy (CNB) or vacuum-assisted biopsy (VAB), excision by VAB in preference to open surgery, and for atypical ductal hyperplasia (ADH) and phyllodes tumors (PT) diagnosed at VAB or CNB, first-line open surgical excision (OE) with follow-up surveillance imaging for 5 years.

Background: The utilization of cancer-linked genetic alterations for categorizing patients against optimal treatment is becoming increasingly popular, especially in non-small cell lung cancer (NSCLC). However, disadvantages of the conventional techniques, such as the low throughput and limited detectable alteration types, lead to the demand of large-scale parallel sequencing for different forms of genetic variants.
Methods: We evaluated the potential of performing next-generation sequencing (NGS)-based methods in a cohort of 61 treatment-naive NSCLC patients to profile their driver mutations, using a panel consisting of 8 well-established driver genes of lung cancer. Read More

The standard therapy for thyroid cancer is total or near total thyroidectomy, followed by the administration of radioactive iodine for remnant ablation or residual disease. Patients with radioiodine therapy are predisposed to second malignant neoplasms in organs such as central nervous system (CNS), breast, prostate, kidney, bone marrow, salivary gland, and digestive tract. Exposure to carcinogen including occupational and therapy related hazard, aging and genetic susceptibility are other causes of second primary cancers. Read More

Papillary thyroid carcinoma (PTC), a common form of thyroid malignancy, displays significant variations in clinical features and outcome. The malignant transformation of the thyroid is driven by altered expression of many matrix-modulating enzymes, including matrix metalloproteinase-9 (MMP-9). A single nucleotide polymorphism in its promotor (-1562 C/T) is suspected to cause overexpression of MMP-9, which in turn contributes to development of a tumour unfavourable phenotype. Read More
