Molecular patterns of egyptian patients with non-squamous non-small-cell lung cancers: a clinicopathological study.

Background: Driver molecular aberrations, such as epidermal growth factor receptor (EGFR) mutation and anaplastic lymphoma kinase (ALK) gene rearrangement, play an important role in the oncogenesis and progression of non-squamous non-small-cell lung cancers (NSCLC). Therefore, this study aimed to detect the incidence of driver mutations among non-squamous NSCLC.

Patients And Methods: This was a retrospective-prospective cohort study on 131 patients with non-squamous NSCLC.

Occurrence of pulmonary residuals as one of the sequelae of COVID-19 and it's predictors among moderate and severe cases.

Background: Moderate and severe COVID-19 patients typically present with pneumonia. In this study we aimed to detect the occurrence of pulmonary residuals as a late sequela of COVID-19 and to identify it's predictors among moderate and severe cases.

Methods: This observational prospective study involved 85 COVID-19 patients confirmed by real time polymerase chain reaction (RT-PCR) nasopharyngeal swab, patients were recruited in the period of 1 st of June to 1 st of July.
