Anaplastic lymphoma kinase (ALK) rearrangement is a predictive factor of response to ALK inhibitors in non small cell lung cancer (NSCLC). The prevalence of ALK rearrangements is well known in Whites and Asians. However, data identifying the frequency of this rearrangement in Moroccan and North African population are lacking. The objective of this study is to report the frequency of ALK rearrangement in a group of Moroccan patients with NSCLC. A retrospective study was performed enrolling 120 Moroccan patients with NSCLC whose biopsy samples were tested for ALK rearrangement in order to identify the frequency of ALK rearrangement and its potential association with selected variables. The ALK testing was established using fluorescent in situ hybridization (FISH) or immunohistochemistry (IHC). The frequency of ALK rearrangement was 4.2% (5/120). All positive cases were males with advanced adenocarcinoma. ALK rearrangements prevalence was significantly higher in older patients. The frequency of ALK rearrangements among the Moroccan population tends to correlate with the average frequency reported worldwide, with some specific features. Further prospective studies with larger patients' numbers are needed to verify these findings.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.
