, and Mutational Profile of Colorectal Cancer in a Series of Moroccan Patients.

Objectives: The present study aimed to evaluate the frequencies of , and mutations and their possible associations with clinicopathological features in 249 Moroccan patients with colorectal cancer (CRC).

Methods: A retrospective investigation of a cohort of formalin-fixed paraffin-embedded tissues of 249 patients with CRC was screened for // mutations using Idylla™ technology and pyrosequencing.

Results: , and mutations were revealed in 46.

Advanced Non-small Cell Lung Cancer: EGFR Mutation Analysis Using Pyrosequencing and the Fully Automated qPCR-Based Idylla System.

Background: Epidermal growth factor receptor (EGFR) mutation status is of a major clinical significance in non-small cell lung cancer (NSCLC) management, as it guides therapeutic decision making to target patients for a better response to therapy. This implicates the introduction of EGFR mutation analysis as the standard of care for Moroccan NSCLC patients, which in itself entails the implementation of targeted methods for routine EGFR mutation analysis in our laboratories. In this study, we aimed to present 2 targeted methods for EGFR mutation identification and to determine the prevalence and spectrum of EGFR mutations in NSCLC Moroccan patients.

Open window thoracostomy for a chronic calcified pleural empyema in the setting of a closed chest trauma.

This case report is a chronic calcified pleural empyema in a patient who suffered a closed chest trauma 30 years ago. The first goal is to demonstrate how the closed chest trauma caused a bronchopleural fistula of the calcified pleural empyema, since the patient began to report continued purulent sputum after his trauma with weight loss and the appearance of an air-fluid level in the chest CT scan (no pleurocutaneous fistula in the clinical examination). The second goal is to reveal the rule and the interest of an open window thoracostomy in the management of chronic calcified pleural empyema, since a decortication remains difficult to perform in cases like this one.

Frequency and types of mutations in Moroccan patients with non-small cell lung cancer.

Background: Mutations in the epidermal growth factor receptor () gene are commonly observed in non-small cell lung cancer (NSCLC), particularly in adenocarcinoma histology. The frequency of mutations is ethnicity-dependent, with a higher proportion reported in Asian populations than Caucasian populations. There is a lack of data on these mutations in north Africa.
